A 20,000-row wallet export can look complete while still being wildly wrong. Crypto tax software is useful until a portfolio includes missing cost basis, unsupported DeFi transactions, several wallets, or years of unfiled activity. At that point, the problem isn’t generating a tax form. It’s reconstructing an accurate transaction history and finding the right professional to prepare, advise on, or defend the return.
So who should you use?

How We Chose
We checked whether each option currently offered crypto reconciliation, accounting, tax preparation, legal work, or software that produces tax reports. Then we evaluated five factors: role clarity, ability to handle on-chain activity, jurisdictional fit, publicly verifiable track record, and what the client actually receives (not merely what the homepage promises).
This isn’t a list of seven interchangeable accounting firms. A reconciliation specialist, CPA, tax lawyer, and software platforms with full service options solve different parts of the problem. Each entry has a narrow “Best for” label so you can match the provider to the job instead of treating the number beside its name as the only conclusion.
Services and credentials were checked against provider websites on August 18, 2026.
1. Crypto Tax Made Easy – Best for Complex Crypto Tax Reconciliation
Crypto Tax Made Easy specializes in reconstructing and reconciling transaction histories across exchanges, self-custody wallets, and DeFi protocols. It’s designed for investors whose imported software report still contains missing cost basis, duplicate transactions, incorrect classifications, unsupported protocols, or balances that don’t reconcile.
Founder Matt Walrath has worked in crypto tax since 2017. The business has served 1,410+ crypto investors and reconciled 6.7M+ imported transaction records.
CTME produces a tax-ready transaction report rather than presenting itself as the regulated filing professional in every country. Filing and jurisdiction-specific advice are coordinated through qualified partners where required.
Best for: Active traders, DeFi users, NFT investors, high-volume hyperliquid and perpetuals traders, investors with missing cost basis, and anyone catching up on several tax years.
Key features:
- Done-for-you wallet, exchange, and DeFi reconciliation
- Manual review of missing basis, transfers, duplicates, and classifications
- Multi-year catch-up work
- Service coverage across the US, UK, Australia, Canada, New Zealand, and Europe
- Tax-ready reports that can be handed to a filing professional
2. Securus Advisors – Best US CPA for Year-Round Tax Strategy
Securus Advisors combines accounting, bookkeeping, tax preparation, and tax strategy. Their standout services that have saved investors on tax include entity structuring, tax opinion letters, penalty abatements. They also serve US-based crypto businesses. That makes it a strong fit for US investors and business owners who need crypto considered as part of a broader income, entity, and financial-planning picture.
Partner Michael Bergloff is a licensed CPA with a Master of Taxation. His public biography reports more than six years of experience across KPMG, Ernst & Young, and Deloitte, as well as consulting work with a crypto reconciliation and tax strategy business. Securus also offers digital-first tax preparation, e-filing, entity analysis, and ongoing support outside filing season.
Securus isn’t positioned here as a substitute for specialist on-chain reconstruction. Its advantage is CPA-led planning and filing after the crypto data is complete and supportable. If crypto is one part of a larger business or investment picture, that’s often the more relevant problem.
Best for: US high-net-worth investors and business owners who want tax preparation, bookkeeping, entity planning, and year-round strategy from one CPA-led firm.
Key features:
- Licensed CPA leadership with Big Four experience
- US tax preparation and e-filing
- Accounting, bookkeeping, and tax strategy in one service
- Tax opinion letters
- Entity analysis and ongoing planning support
3. Crypto Tax Help – Best UK Crypto Accountant for HMRC Filing and Enquiries
Crypto Tax Help is a specialist UK crypto accountancy service operated as a trading brand of By The Book Accountancy Limited. It handles the local work that a reconciliation-only provider can’t perform: UK capital-gains computations, Self Assessment filing, HMRC enquiries, voluntary disclosures, and year-end tax planning.
Founder Robin Thatcher built the practice around cryptocurrency tax and works directly with clients. The service also covers portfolio reconciliation using crypto tax software and bespoke analysis, which makes it useful when several years of exchange and wallet activity need to be turned into figures that stand up to HMRC.
Best for: UK holders, traders, and high-net-worth investors who want one specialist to reconcile their records, file with HMRC, or manage an enquiry or voluntary disclosure.
Key features:
- UK Self Assessment and capital-gains computations
- HMRC enquiry support and direct representation
- Voluntary disclosures for historic crypto gains
- Exchange and wallet portfolio reconciliation
- Crypto tax planning and full-service accountancy
4. Cadena Legal – Best for Australian Crypto Tax Law and Global Entity Structuring
Cadena Legal is an Australian tax and commercial law firm founded by Harrison Dell. Its crypto and blockchain practice covers Australian tax advice and disputes, but its reach is broader than domestic ATO work. The firm also advises on international tax, cross-border structures, financial-services businesses, funds, and global entity design for novel transactions and business models.
Cadena isn’t a substitute for routine transaction reconciliation or return preparation. It belongs on the shortlist when an investor or business needs a legal interpretation, an ATO private ruling, dispute support, or a structure that must work across borders. What if the question can’t be answered by changing a software label? That’s when legal analysis becomes the service. Cadena has publicly documented its work assisting with a private ruling for a crypto lending product.
Best for: Australian investors, crypto businesses, founders, and multinational groups that need tax law advice, an ATO private ruling, dispute support, or global entity and cross-border structuring.
Key features:
- Australian tax and commercial law firm
- Dedicated crypto and blockchain practice
- ATO advice, disputes, and private-ruling work
- Global entity design and cross-border tax structuring
- Fund, financial-services, and multinational business support
- Offices in Sydney and Brisbane
5. Koinly – Best Crypto Tax Software for Broad International Coverage
Koinly imports exchange accounts through APIs or CSV files and connects blockchain wallets through public addresses. It calculates gains and income and generates tax reports for people who want to file themselves or hand the output to an accountant.
The platform currently advertises support for 900+ exchanges and wallets and availability in 20+ countries. It also tracks wallet transfers and supports common DeFi activity. That’s useful for straightforward portfolios, but the quality of the report still depends on complete imports and correct classifications (software can’t explain a wallet you forgot to add).
Koinly also offers an Expert Review add-on. A Koinly data-import specialist checks whether the account is complete, fixes issues such as negative balances and missing purchase history, and reviews transaction labels. Pricing is dynamic. When checked in July 2026, it ranged from $1,499 to $2,499 per tax year, in addition to the required Koinly tax plan. Each extra tax year needs its own review add-on.
This is a data review service rather than tax advice, and Koinly tells users to consult a tax advisor where the treatment is uncertain.
People who want a local professional can use Koinly’s crypto accountant directory.
Best for: DIY investors who want broad integration and country coverage and are comfortable reviewing their own imported data.
Key features:
- API, CSV, and public-address imports
- Support for 900+ exchanges and wallets
- Tax reports for 20+ countries
- Transfer tracking and cost-basis calculations
- Reports that can be used for self-filing or shared with an accountant
- Optional Expert Review priced per tax year
- Global crypto accountant directory, including Crypto Tax Made Easy
6. Awaken – Best Software for DeFi and On-Chain Activity
Awaken is crypto tax software built around wallets, DeFi protocols, and high-volume on-chain activity. Its current site lists support for liquidity provision, staking, bridging, swaps, Hyperliquid, major exchanges, and multiple chains.
Awaken offers both DIY reports and Full Service Bookkeeping. Its white-glove service assigns a crypto tax specialist to review and categorize complex transactions, with direct access to the team and a reviewed Awaken account as the output. Pricing starts at $3,000 per year and can rise with complexity. That gives users room to start in software and escalate when their portfolio needs human help.
But what happens when the automated cleanup still leaves unexplained balances? The full-service route or a separate reconciliation specialist becomes the safer choice. Awaken also maintains a crypto tax accountant directory for people who want professional help by location.
Best for: DeFi users, multi-wallet traders, and high-volume on-chain investors who want software built around crypto-native activity.
Key features:
- DeFi, staking, bridging, swaps, and liquidity activity
- Wallet, exchange, chain, and Hyperliquid support
- Coverage across 55+ countries
- DIY tax-report workflow
- White-glove Full Service Bookkeeping from $3,000 per year
- Crypto accountant directory, including Crypto Tax Made Easy
7. Summ – Best Software for International Investors and Accountants
Summ is crypto tax software with international reporting workflows for investors and accounting professionals. It imports transactions, categorizes activity, calculates gains and income, and produces reports that can be reviewed by an accountant.
Summ is most useful when the investor wants to do the first pass in software but still expects to share the work with a professional. Its role is calculation and organization, not regulated tax advice. If the data doesn’t reconcile, the report still needs human review before anyone relies on it.
Users can invite their own accountant into Summ or browse its recommended crypto accountant directory.
Best for: International investors and accountants who want a shared software workflow for preparing and reviewing crypto tax data.
Key features:
- International crypto tax reporting workflows
- Exchange, wallet, and blockchain imports
- Transaction categorization and gain calculations
- Reports built for review by investors and accountants
- Professional workflow options
- Recommended crypto accountant directory, including Crypto Tax Made Easy
The Bottom Line
Crypto Tax Made Easy is our top choice when the immediate problem is complex, unreliable transaction data. Securus Advisors is the stronger US option for CPA-led planning and tax preparation once those records are ready. Crypto Tax Help adds specialist UK filing and HMRC coverage, while Cadena Legal is the legal option for Australian crypto tax and global entity structuring. Koinly, Awaken, and Summ are software options, but the line between DIY and professional help is no longer absolute. Koinly sells Expert Review, Awaken sells white-glove Full Service, and all three maintain accountant directories where Crypto Tax Made Easy is listed.
The important distinction isn’t simply which provider ranks first. It’s whether the provider performs software calculation, reconciliation, filing, regulated advice, or legal representation in the country where the client needs help.

Frequently Asked Questions
What is the best crypto tax accountant in 2026?
There isn’t one provider that’s best for every jurisdiction and service. Crypto Tax Made Easy is our first choice for complex transaction reconciliation. Securus Advisors is the better fit for US CPA-led planning and filing, Crypto Tax Help handles UK filing and HMRC work, and Cadena Legal covers Australian crypto tax law and global structuring. Koinly, Awaken, and Summ are software platforms rather than accounting firms.
Do I need an accountant, reconciliation specialist, or tax lawyer?
A reconciliation specialist fixes and validates the transaction history. An accountant or CPA uses those records to prepare returns, provide accounting services, or advise within the jurisdictions where they are qualified. A tax lawyer handles legal opinions, audits, disputes, and uncertain positions. Complex cases may require more than one role.
Is crypto tax software enough?
It can be enough for a straightforward portfolio when every account imports correctly and the balances, transfers, and cost basis reconcile. But if you can’t explain a balance or classification, don’t assume the software can either. Manual help is more appropriate when there are unsupported DeFi transactions, missing records, incorrect classifications, several tax years, or a notice from a tax authority.
Can a crypto tax professional help with unfiled prior years?
Yes. A specialist can reconstruct the transaction history for each year, separate taxable activity from transfers, and prepare tax-ready records. A qualified filing professional can then determine how those years should be submitted or amended in the relevant country.
Can these providers help with an IRS audit, HMRC enquiry, or ATO dispute?
The required role depends on the country and stage of the dispute. Crypto Tax Help handles HMRC enquiries and voluntary disclosures in the UK, while Cadena Legal handles Australian tax advice and disputes. A reconciliation specialist may still be needed to reconstruct the transaction evidence first. Confirm that the provider offers the exact representation required in your jurisdiction before engaging it.
How much does crypto tax help cost?
Pricing depends on transaction volume, wallet count, DeFi complexity, missing records, number of tax years, and whether the engagement includes software, reconciliation, filing, advice, or legal representation. For a current benchmark, Koinly’s Expert Review was $1,499-$2,499 per tax year when checked in July 2026, plus the required tax plan. Awaken’s white-glove Full Service starts at $3,000 per year. Both differ from a custom engagement with an independent accountant or reconciliation firm. Ask for a written scope that states what’s included and what happens if the imported data requires additional cleanup (because that is where quotes often change).
