How to Choose a Crypto Tax Accountant in Japan (2026 Guide)

Are you facing serious obstacles when it comes to filing your annual tax return — things like: “I kept trading on overseas exchanges and decentralized apps, and my gain/loss calculation tool started throwing so many unidentified-transaction errors that I couldn’t keep up on my own,” or “My regular tax accountant turned me down, saying that crypto assets (also known as virtual currencies) are outside their area of expertise”?

Crypto tax rules are updated on an ongoing basis, and it is extremely difficult — both mentally and technically — for individual investors or general accounting firms to determine an accurate taxable income figure entirely on their own. Filing an inaccurate return based on vague treatment of the many gray areas in crypto taxation carries the risk of a subsequent tax audit resulting in a harsh penalty in the form of a substantial additional tax assessment.

This article walks you through the tax pitfalls investors commonly run into and the right moment to switch to professional help. We provide a clear, easy-to-follow guide to identifying a trustworthy, specialized tax accounting firm — one that can be a strong ally for investors struggling with high transaction volumes and complex bookkeeping, and that can seamlessly support everything from reliable tax-saving strategies to simulations for incorporating as a company.

Why Filing Crypto Taxes Requires a Specialized Tax Accountant

The tax filing framework for crypto assets differs structurally from both ordinary business-income tax filing and other financial products subject to separate self-assessment taxation.

When investors attempt the calculations entirely on their own, the risk of incorrect tax treatment resulting in a substantial additional tax assessment is far from negligible. Engaging a tax accountant with specialized expertise is considered essential for the following two reasons.

① Strict regulatory framework

② Practical complexity of the calculations

Crypto Gains Are Classified as “Miscellaneous Income” Under Aggregate Taxation

Under the Income Tax Act, profits (income) generated from selling or exchanging crypto assets are, in principle, classified as miscellaneous income and treated as subject to aggregate taxation (comprehensive taxation).

Its defining feature is that the applicable tax rate is determined after combining this income with other income subject to aggregate taxation, such as employment income and business income. Because Japan’s income tax uses a progressive tax rate structure, the rate rises in stages as taxable income increases, reaching a maximum of approximately 55% when combined with the flat 10% resident tax.

Gains or losses arising from crypto asset transactions are recognized as gains or losses in relation to the Japanese yen or a foreign currency, and are therefore, in principle, classified as miscellaneous income (other miscellaneous income).

As shown above, listed stock trading conducted through a securities firm, or FX trading under the Act on Special Measures Concerning Taxation, is taxed at a flat rate of roughly 20% no matter how large the profit. Crypto asset trading, by contrast, means that larger profits translate directly into a higher tax rate, so the financial impact on investors can be extremely heavy. This difference in taxation structure is the single most important point to keep in mind when managing crypto-related taxes.

Note for readers (as of July 2026): Under the currently applicable law, gains from selling crypto assets are treated as miscellaneous income under aggregate taxation, as described above. On July 15, 2026, however, an amended Financial Instruments and Exchange Act (FIEA) was passed by Japan’s House of Councillors, which will move crypto assets under the FIEA’s definition of financial instruments. Once the amended law takes effect — expected from January 2028 — a flat 20% separate self-assessment tax rate is expected to apply to crypto gains, similar to the treatment of stocks and FX described above.

No Offsetting of Gains and Losses, and Complicated Calculations

The tax system governing crypto assets does not extend the various tax benefits available to other investment products. When building an investment strategy, the following two points impose extremely serious constraints.

• No offsetting of gains and losses: Except for offsetting within the same category (i.e., within miscellaneous income), losses from crypto asset transactions cannot be deducted from other income, such as employment income, real estate income, or gains from the sale of stocks.
• No carry-forward deduction: For investments in listed stocks and similar products, a loss incurred in a given year can be carried forward for up to three years and offset against future gains. Losses on crypto assets, however, cannot be carried forward to subsequent years at all and are simply forfeited at year-end.

Under the Income Tax Act, losses that can be offset against other income are limited to losses arising in the calculation of real estate income, business income, forest income, or capital gains. Miscellaneous income does not fall into any of these categories, so even if a loss arises in the calculation of miscellaneous income, it cannot be deducted from (offset against) other income.

In addition to these structural disadvantages, the sheer complexity of calculating gains and losses from day-to-day trading is itself a major obstacle.

In particular, if you use multiple crypto exchanges, you must gather every purchase, sale, and transfer record from each account and sort them all in chronological order. Calculating the accurate acquisition cost per coin using whichever valuation method you have chosen — the total average method or the moving average method — becomes effectively impossible to do by hand in a standard spreadsheet once the number of transactions reaches the hundreds, thousands, or even tens of thousands.

Unlike securities firms, which issue an annual trading report that automatically completes the calculation process, no equivalent system exists for crypto, making it extremely difficult for individual investors to determine an accurate taxable income figure on their own.

Cases Where a General Tax Accountant Struggles to Help

The assumption that “I already have a regular tax accountant, so I’m covered” does not necessarily hold true when it comes to crypto tax. Crypto trading practices have grown increasingly sophisticated alongside advances in technology, and tax firms whose core business is corporate financial statements and standard income tax filings frequently find themselves unable to proceed.

In particular, investors engaged in the following types of Web3 transactions are not uncommonly turned away by their regular tax accountant, who cites it as being outside their area of expertise.

• Token swaps on DeFi (decentralized finance) protocols, liquidity provision (yield farming), and rewards earned through staking
• Primary sales and secondary trading of NFTs (non-fungible tokens), and receipt of proprietary tokens within blockchain games (BCG)
• Extracting transaction history (CSV data, etc.) with the complex, exchange-specific formats unique to overseas exchanges, and scrutinizing on-chain data

Accurately recording these transactions requires more than just reading the text of the tax code — it requires a structural understanding of how smart contracts and various protocols behave. Without in-depth knowledge of blockchain technology, it is impossible to make sound tax judgments about exactly when a right vests and at what fair market value taxable income arises. As a result, investors are often left needing to seek a second opinion from a tax accountant who specializes in crypto, or to overhaul their relationship with their regular tax accountant entirely.

How to Choose a Tax Accountant Who Specializes in Crypto: 5 Key Checkpoints

To eliminate the risk of mismatched expertise or missed filings and to complete the process safely, you need to rigorously evaluate any tax accounting firm before hiring it. Here are five criteria you should always check when selecting a tax accountant to handle your crypto tax filing.

① Track Record and Volume of Crypto Tax Filings

The most important objective indicator is the firm’s concrete track record in crypto-related tax filings and its annual case volume to date. Even a firm that claims “crypto asset support is available” may still make errors when handling complex transactions if it has actually only handled a handful of cases per year. A firm that clearly maintains a dedicated “crypto-focused” service line or a dedicated “virtual currency desk” on its website is more likely to respond quickly to the latest tax reforms, NTA guidelines, and blockchain trends, and is worth trusting on that basis. Whether the firm discloses past case examples or its cumulative filing count is also an important factor in your decision.

② Support for Gain/Loss Calculation Tools (cryptact / Gtax)

Using a widely recognized dedicated gain/loss calculation tool has effectively become the standard practice for accurately computing crypto tax figures. When choosing a firm, you should confirm whether the assigned tax accountant is genuinely proficient in operating leading calculation tools such as cryptact or Gtax.

A firm equipped to handle these systems can take the transaction history (CSV data, etc.) exported from each exchange you use and handle everything from importing it into the tool to detecting and correcting error data on your behalf. Whether or not a firm has an established integration with these calculation tools is a major dividing line in how dramatically it can reduce your own workload.

③ Ability to Handle DeFi, NFTs, and Staking

If your own trading involves DeFi (decentralized finance), NFT purchases and sales, or staking, how deeply your tax accountant understands these mechanisms will determine whether the engagement succeeds. During your initial meeting or inquiry, you should present the specific on-chain transactions you have carried out and ask directly whether the firm can substantiate them and prepare your return accordingly.

Whether the firm has the practical capability to scrutinize on-chain transaction history from a non-custodial personal crypto wallet (such as MetaMask) and post the corresponding journal entries is an extremely important criterion for investors engaged in advanced trading.

④ Clarity of the Fee Structure

Fee structures for tax accountants vary widely from firm to firm. For crypto tax filing support, unlike ordinary tax filing, it is common for fees to be added in stages depending on factors such as the annual number of transactions, the number of exchanges used, and whether overseas exchanges or DeFi are involved.

Before signing a contract, you need to be completely clear on exactly what scope of work is included in the base fee and under what circumstances additional charges apply. Choosing a transparent firm that presents a detailed fee table at the quotation stage is essential for preventing money disputes down the line.

⑤ Responsiveness and Ease of Communication

The tax filing period is tightly limited, running from mid-February to March 15 each year, and firms become increasingly busy as the deadline approaches. Whether a firm responds quickly in day-to-day communication is therefore a quietly powerful factor in managing the process without unnecessary stress.

You should confirm whether the firm can flexibly accommodate online meetings and consultations via chat tools (Slack, LINE, Chatwork, etc.), and whether it has a system in place to respond quickly whenever an urgent question comes up.

Recommended Firms That Specialize Exclusively in Crypto

Navio Tax Corporation

Founded in 2017, Navio Tax Corporation is a team of specialists that has worked on crypto tax matters since an early stage. It employs tax accountants holding the JCTA-certified Crypto Tax Advisor qualification, and provides precise tax judgments in line with the NTA’s latest views and tax reforms even amid the fast-changing crypto tax landscape.

The firm’s greatest strength is its high level of analytical capability for complex on-chain data and specially formatted transaction records that existing calculation tools cannot fully handle. Its coverage extends well beyond ordinary spot trading to advanced transaction types such as staking, lending, mining, DeFi (decentralized finance), and NFT trading. Even if you find yourself in a situation where transaction data is incomplete or missing because you use multiple overseas exchanges or personal wallets, the firm is set up to support you consistently through additional detailed interviews and supplementary information to produce as accurate a gain/loss calculation and tax return as possible.

It is also reassuring for investors that the fee structure is published clearly on the firm’s website. Its “Crypto Plan,” which includes crypto income calculation, starts at JPY 110,000 (approx. USD 730) per year for the Light Plan, aimed at annual turnover under JPY 10 million (approx. USD 66,700), with a graduated fee table based on turnover. The firm also offers comprehensive backup beyond just filing support, including attendance at tax audits should one occur (JPY 88,000, approx. USD 590, per day) and a tax consultation hotline for everyday questions.

Tamaranzaka Tax Accountant Corporation

Tamaranzaka Tax Accountant Corporation is a firm registered as a member of the Japan Crypto-asset Business Association (JCBA), a general incorporated association. Its standout feature is that all three of its tax accountants, along with its office staff, are former tax officials who previously worked at the National Tax Agency or a local tax office. Because these former NTA officials — who know the realities of tax audits inside and out — directly oversee the practical work, the firm can prepare extremely precise returns that comply with NTA administrative guidelines. Client work is never handed off to unqualified staff or part-timers; every case is handled directly by a qualified professional.

In practice, the firm has been fully engaged in crypto tax work since its tax accountant registration in 2018, with expertise notable enough that it runs crypto tax seminars for other tax accountants. Its coverage goes beyond spot trading to include analysis of overseas exchange records and complex profit calculations for staking, lending, and various DeFi protocols. On the calculation side, it has a business partnership with pafin Inc., which operates the automated gain/loss calculation system cryptact, giving it a strength in high-precision data review.

As a further forward-looking touch worth noting, the firm accepts Bitcoin (BTC) payments for its fees. It has also built a fully remote online consultation system using tools such as Zoom, allowing clients anywhere in Japan to receive top-tier tax audit preparation and filing support regardless of location.

Whitetec Accounting Office

Based in Minami-Ikebukuro, Toshima Ward, Tokyo, and offering remote support via web conferencing to clients across Japan, Whitetec Accounting Office is a specialist firm that has been on the front line of crypto tax practice since 2017. Its greatest strength lies in the unusually deep industry background of its lead tax accountant (a JCTA-certified Crypto Asset Advisor), who has direct experience conducting financial statement audits and segregated-custody audits at crypto exchange operators. The firm has also served as a court-appointed assistant in what is said to be Japan’s first crypto-related tax litigation case, and has a track record of giving seminars for other tax accountants and writing for specialist publications — depth of knowledge that earns it respect from peers in the field.

In practice, the firm goes well beyond simple spot-trading gain/loss calculations to fully handle cutting-edge, specialized transaction analysis for corporate-individual transactions, gifts, over-the-counter trades, ICOs, DeFi, NFTs, and blockchain games (BCG). It has official business partnerships with leading gain/loss calculation system vendors such as cryptact and Cryptolinc, and combines system checks with a rigorous multi-person internal cross-check process to thoroughly prevent the kind of calculation errors or data omissions that could shift reported profits by tens of millions of yen.

Its fee structure is also transparent: crypto gain/loss calculation starts at a guideline price of JPY 275,000 (approx. USD 1,830) including tax for exchange-only trading, or JPY 495,000 (approx. USD 3,300) if DEX and DeFi activity is included (with an additional JPY 55,000, approx. USD 370, per fiscal year if a tax return also needs to be filed). The firm has been certified as an “Approved Support Organization for Business Innovation, etc.” by a regional Bureau of Economy, Trade and Industry, and its appeal lies in its all-around capability: beyond individual filing representation, it can handle everything from building various crypto tax-saving schemes and simulating incorporation, to preparing for a tax audit covering past returns.

SKIP Tax Corporation

Headquartered in Nibancho, Chiyoda Ward, Tokyo, SKIP Tax Corporation is a forward-looking firm with strength in supporting IT companies and startups, as well as expertise in crypto assets, NFTs, and blockchain games (BCG). It has extensive practical know-how for handling complex transactions involving overseas exchanges, decentralized exchanges (DEXs), and DeFi, as well as NFT purchases and sales. In its data processing and profit calculation workflow, it maintains a tight system integration with the leading gain/loss calculation tool Gtax, providing a foundation for aggregating and reviewing even massive transaction histories quickly and with a high degree of accuracy.

One characteristic of the firm is its finely segmented fee plans, tailored to an investor’s needs and trading scale. Plans are staged according to transaction volume and content — ranging from a plan for clients who calculate their own crypto gains and losses but want data verification and return preparation outsourced, up to a full “leave-it-all-to-us” plan that hands over all data aggregation (detailed pricing is quoted individually based on transaction content).

The firm also operates a fully online setup, letting clients seamlessly get everyday tax advice via chat tools and conduct web-based meetings from anywhere in Japan, regardless of location. Beyond supporting individual tax filings, one of its major strengths is its ability to comprehensively support corporate financial statements for companies holding crypto assets and to simulate incorporation involving crypto assets.

Omi Tax Accountant Office

Omi Tax Accountant Office is a firm whose principal, tax accountant Mitsuo Omi, was an early mover in focusing on crypto tax and has built a strong track record supporting individual investors and Web3 businesses. Omi himself is the author of a specialist book that reached the No. 1 bestseller ranking in Amazon’s accounting category, and is known for actively appearing in media and lecturing at crypto tax-saving seminars. The firm’s defining feature is that it puts practical tax-saving consulting front and center — aimed at maximizing what investors actually keep — rather than limiting itself to after-the-fact filing representation based solely on processing past transaction data.

In practice, the firm has extensive support experience not only in individual tax filing but also in reducing the tax burden for investors whose profits have grown large, through incorporation (setting up a company to hold crypto assets). It has built a system that can handle everything consistently, from the incorporation process itself through to ongoing monthly advisory tax work after the company is set up, making it capable of comprehensive support as a long-term tax partner. It is also skilled at helping clients build an efficient back-office system using cloud accounting software, and offers a reasonable advisory fee starting at JPY 9,800 (approx. USD 65) per month including tax — meeting the needs of clients who want thorough support while keeping costs down.

The firm also closely tracks changes in legal interpretation by the National Tax Agency and trends in tax audits, and is thorough about preparing extremely robust returns with a tax-office perspective in mind. This gives it the defensive capability to make sound, legally grounded arguments should a tax audit ever occur — a major reason it is chosen by many large-scale investors. For investors seeking reliable filing and proactive tax planning while minimizing risk within the bounds of the law, it stands out as a highly trustworthy option.

Kaoria Accounting Office

Fujimoto has published several books on crypto assets and has a track record of numerous lectures and seminars, including at Toyo University and bitbank. His depth of knowledge and credibility within the industry are held in extremely high regard.

For its practical gain/loss calculation process, the firm’s strength lies in data analysis using its own in-house-developed calculation system, Cryptorch. It really proves its worth in areas where general-purpose aggregation software tends to generate frequent errors, such as tracking arbitrage trades across overseas exchanges or complex transactions occurring across various DeFi protocols. It also builds accurate journal entries in line with the NTA’s latest administrative notices for processes requiring advanced legal scrutiny, such as acquisitions of new coins from a hard fork or fair-value assessments of unidentified tokens.

Beyond filing representation for individual investors, the firm is also well regarded for handling year-end fair-value assessment of crypto assets held by corporations and for its highly specialized consulting for Web3 businesses and startups. Its defining feature is comprehensive backup that reflects the latest developments in tax practice at every stage, from the initial consultation through data review and actual return preparation to preparation for a future tax audit.

Tax Corporations That Also Handle Crypto-Related Work

The table below compares capable tax accounting firms that offer crypto tax filing and consultation services. Use the location, level of support, tool integration, and approximate fees of each firm to help narrow down the office that best fits your situation.

• *1: Regarding “Tsuji Sogo Kaikei Tax Corporation” — This is a completely separate, independent firm from Tsuji-Hongo Tax Corporation, one of the largest firms in the industry. Because the names are extremely easy to confuse, please take care not to mix them up when making an inquiry. The operating entity behind it is m-assets, and it has been confirmed that the information is published directly by Mitsuaki Tsuji, a certified public accountant and tax accountant.
• *2: Regarding the domain of “Yell Tax Corporation” — The URL for the firm’s dedicated crypto page uses the unusual domain name “sugoigundam.jp.” This is, however, an official, verified website operated by the firm itself. As a tax corporation with five offices nationwide centered on its Nagoya head office, you can access it with confidence.

All four firms listed above are reliable options that have been confirmed to either explicitly state crypto support on their websites or maintain a dedicated consultation desk. If you feel you have reached the limits of calculating gains and losses on your own, or are struggling with the journal entries for complex overseas transactions, we recommend using these firms’ free consultations or quote services before it’s too late.

Large General Firms for Investors Who Value Scale and Stability

For investors who would rather prioritize a firm’s overall organizational scale and the reassurance of a nationwide network of offices over a crypto-specialist boutique, here are some of Japan’s largest tax corporations. Their approach differs from that of specialist firms in terms of flexibility and Web3-specific transaction analysis capability, but they are a strong option for anyone who values a well-organized institutional backup structure.

*A note regarding “Tsuji-Hongo Tax Corporation”

This is a completely different firm from the previously mentioned “Tsuji Sogo Kaikei Tax Corporation.” Tsuji-Hongo Tax Corporation is one of Japan’s largest tax corporations, with more than 80 offices nationwide. Please be careful not to confuse the two.

Large general tax corporations with a nationwide footprint have overwhelming stability as their strength, backed by strong organizational capacity and an extensive track record of handling tax audits. They may lack some of the on-chain analysis flexibility of specialist boutiques, but they produce extremely robust returns that comply with NTA administrative notices. Because of their organizational continuity, which allows them to respond consistently even to a tax audit years down the line, they are a highly reliable option for corporations and large-scale investors (“oku-ri-bito,” or crypto millionaires) who prioritize rigorous legal compliance above all else.

The Filing Process and Required Documents

To ensure a smooth engagement with your tax accountant, it’s important to understand the overall workflow and what advance preparation looks like.

Timeline From Engagement to Filing

The standard schedule for crypto tax filing is as follows. Rather than waiting until just before the filing deadline (in principle, March 15), it’s recommended that you start early, between December and February.

1. December–February | Initial consultation and contract
   • Inquire with tax accounting firms and receive quotes
   • Sign the contract and share required documents (transaction history, etc.)
2. February–early March | Gain/loss calculation and document preparation
   • Aggregate profits using dedicated tools and on-chain data
   • Correct error data and prepare the tax return
3. Up to the filing deadline | Filing and payment
   • Final review by the tax accountant, electronic filing (e-Tax) with the tax office
   • Completion of income tax payment procedures

Compared with ordinary business income, calculating gains and losses on crypto tends to require significantly more time for detecting error data and scrutinizing unclear transactions. Because tax accounting firms also have limited capacity, it’s safest to complete your initial consultation before the year is out, or by January at the latest. Note that while the filing deadline is, in principle, March 15, it moves to the next business day if that date falls on a weekend or public holiday.

What to Gather in Advance

To get a smooth start on consulting with a tax accountant and beginning the gain/loss calculation work, the accuracy of your advance data preparation is what makes or breaks the process. The most time-consuming part of crypto tax work is identifying gaps or missing pieces in the data, so having accurate documentation ready in advance reduces the accountant’s workload and helps prevent delivery delays or additional fees.

The specific documents you should prepare are as follows, and listing all of them without omission is an absolute prerequisite for calculating an accurate tax amount.

• Transaction history data (CSV, etc.) from every crypto exchange you use
  • Beyond the “annual trading report” issued by domestic exchanges, you’ll also need the “CSV-format transaction history (Trade History)” and “deposit/withdrawal history” exported from overseas exchanges. Because some overseas exchanges cannot retroactively export data from several months prior, backing this up early is essential.
• Transfer and transaction history from personal wallets (on-chain data)
  • If you use a personal wallet such as MetaMask, provide the address (public key) for every wallet you’ve used. All transactions — including DeFi swaps and NFT purchases and sales — need to be traceable.
• Income/expense records from mining, lending, and similar activities
  • These are records of crypto acquired outside an exchange, through mining, staking, lending, affiliate rewards, and the like. Because you need to determine the fair value (converted to Japanese yen) at the time each reward was received on an individual basis, you’ll need to submit logs that clearly record the date, time, and quantity.
• A copy of last year’s tax return
  • If you have filed before, a copy of the prior year’s return is essential. This document is indispensable in practice for confirming the continuity of the valuation method you previously chose (moving average method or total average method) and for correctly carrying forward the opening book value (the valuation of carried-over assets).

Calculating crypto gains and losses breaks down unless the acquisition cost is properly linked all the way back through every asset you’ve ever held. If you’ve imported your data into an aggregation tool yourself and are seeing errors (such as unidentified tokens), preparing a screenshot of that screen along with notes on the unusual transactions that caused the error (hard forks, airdrops, etc.) will make your tax accountant’s legal review dramatically smoother.

If You Want to Calculate Your Own Gains and Losses

If you’d rather not hand everything over to a tax accountant and instead want to keep costs down by filing on your own first, the usual approach is to use a dedicated crypto gain/loss calculation tool (a SaaS product) rather than calculating by hand. However, depending on the complexity and volume of your transactions, aggregating the data yourself can become difficult even with a tool, so it’s important to understand the characteristics of each tool correctly.

Differences Between the Major Tools

Below is a comparison of the number of supported exchanges and level of automation for the three leading gain/loss calculation tools widely used by investors in Japan: cryptact, Gtax, and Cryptolinc.

Crypto gain/loss calculation tools basically work by having you upload a CSV-format transaction history file downloaded from each exchange, or by linking an API, after which they automatically calculate profit and loss based on either the moving average method or the total average method.

cryptact supports an especially large number of exchanges and Web3 protocols, and enjoys overwhelming support from intermediate-to-advanced traders who frequently use overseas exchanges. On the other hand, if your trading is mainly spot trading on domestic exchanges, Gtax, with its intuitive interface, or Cryptolinc, with its strength in system integration, are also strong options.

Regardless of which tool you use, however, be aware that when “transfer cost mismatches” occur from moving coins between exchanges, or “unidentified errors” arise from failing to fetch the price of a minor memecoin, you will ultimately have to correct the data one entry at a time yourself (via correcting journal entries).

When to Switch to a Tax Accountant

Gain/loss calculation tools are convenient, but they can’t automatically calculate every single transaction. When your tool’s screen shows an “unidentified error,” there is a limit to how much you can fix on your own. If any of the following applies to you, it’s time to switch to a professional.

• Your transaction count is high and data inconsistencies (mismatches) are appearing
  • Repeatedly transferring funds and trading across numerous domestic and overseas exchanges makes acquisition-cost calculations prone to going off track. If the volume has grown to the point where checking the data yourself is taking an enormous amount of time, that’s a sign you should outsource it.
• You have complex transactions involving DeFi, NFTs, memecoins, and the like
  • Swaps on minor DEXs (decentralized exchanges), NFT purchases and sales, staking, and similar activity often can’t be automatically analyzed by these tools. Manually recording journal entries for these in compliance with NTA administrative notices is extremely difficult for an individual to do.
• You’re simply unsure whether your calculation results are correct
  • Crypto taxation is still a work in progress legally, and gray areas that are genuinely hard to judge do exist. If you have even the slightest doubt about your own processing, handing it over to a tax accountant can eliminate both the risk of a future additional tax assessment and the mental burden.

Once you feel you’ve hit the limit of what you can aggregate on your own, we recommend consulting a tax accountant who specializes in crypto early on, rather than scrambling right before the filing deadline.

Conclusion: Eliminate Tax Risk and File with Confidence

Crypto taxation is extremely strict, with aggregate taxation reaching up to approximately 55% and no offsetting of gains and losses allowed, and manually journaling “unidentified errors” stemming from DeFi and NFT transactions requires advanced specialized knowledge. Leaving these issues unresolved is a potentially fatal risk that could invite a harsh additional tax assessment, including a heavy additional tax penalty (juka-santo), in a future tax audit.

That said, only a handful of tax accountants on the market are capable of on-chain data analysis in the Web3 space, and once the tax filing season gets into full swing, every firm’s capacity fills up in no time. The moment you feel you’ve hit the limit of calculating gains and losses on your own, or the moment your existing tax accountant turns you away, is exactly the turning point at which you should consider switching to a specialized firm.
