Facing an IRS crypto audit, notice, or letter?
CountDeFi's crypto tax audit accountants provide IRS crypto audit help: we reconstruct your records, establish what you actually owe and prepare the response to a CP2000, a 6174 letter or a full audit, working alongside your CPA or tax attorney where representation is needed. The IRS figure is often wrong. The deadline on the notice is not.
// IRS CRYPTO AUDIT SPECIALISTS
CountDeFi, specialists in IRS crypto audits and notice resolution.
If the IRS is knocking on your door, you need to act. CountDeFi provides specialized tax accounting for US crypto investors under audit or holding an IRS notice. We're not just accountants, we're data scientists who reconstruct your full transaction history to answer the IRS with evidence, not guesswork. If you've had a letter, a CP2000, or a full examination, and the numbers don't match what you actually made, CountDeFi can help with affordable plans.
We operate online and in your time zone.
A Letter With a Deadline Is Scary.
An IRS notice comes with a clock, and ignoring it only makes things worse. We read exactly what they're asking, tell you what it really means, and respond before the deadline. Count on us to back you up.
The IRS Number Is Usually Too High.
A CP2000 is often auto-generated with no idea of your actual cost basis. The IRS can claim that you owe tax on money you never made. We rebuild your real numbers and push back with evidence.
Worried about CPA fees?
Fighting the IRS has a reputation for runaway bills. We don't bill by the hour. Our plans scale with your volume and complexity, and every plan includes the reconstruction, the response, and the finished report.
// who we are
"An IRS crypto letter lands and people panic, but most of the time the notice is built on incomplete data. The exchange reported what you sold and told the IRS nothing about what you paid. We built CountDeFi for exactly this: rebuild the history, prove the real numbers, and deal with the IRS professionally."

The IRS number is a starting point, not the final word
We've been reconstructing complex crypto and on-chain activity since 2017, and we've seen the same pattern over and over. A notice quotes a frightening figure, and it falls apart the moment someone rebuilds the actual cost basis behind it. The hard part is rarely the argument. It's the evidence and the deadline. Exchanges report gross proceeds to the IRS with no record of what you paid, so the system assumes your cost was zero and bills you on the full amount. And every notice runs on a clock, so a strong position is worth nothing if your response misses the window.
This is the reality of crypto in 2026, not an edge case. Millions of 1099s now flow to the IRS, and the mismatches they create are landing are triggering letters, notices and audits. Without rebuilt records and a response filed on time, you can't show what you really owe, and a wrong number can stand simply because nobody answered it properly.
CountDeFi reconstructs the transaction history behind the notice, calculates what you actually owe, and prepares the response the IRS needs to see. Getting an audit handled doesn't have to cost a fortune. We do not bill by the hour. Our pricing scales with transaction volume and complexity, and every plan includes the reconstruction, the response, and a complete supporting report.

Why crypto investors under audit hire CountDeFi
Nobody wants to face the IRS alone, least of all over a crypto history they can barely reconstruct themselves. People come to us for a few simple reasons. They want the letter to stop being a threat, handled by someone who has answered hundreds of them. They want the real number instead of the inflated one, because paying tax on proceeds you never profited from is money straight out of pocket. They want to stay out of deeper trouble, since an unanswered notice can escalate into a full examination. And they want all of it resolved without a bill that rivals the tax itself. That is what we do. We take the notice off your desk, rebuild the records that prove your actual position, respond to the IRS on your behalf, and price the work so it never costs more than it saves. You hand over the letter and the mess, and you get back a clear answer and a response the IRS can accept.

Why tax software can't answer an IRS audit
Tax software is a great starting point, but an IRS notice is not a data-entry problem. Software is not the issue. Koinly, for example, is a genuinely good engine, which is exactly why we use it and why we're Koinly's #1 Global Accounting Partner. But no app or software can read a 6174 letter, rebuild a cost basis that was never recorded, or file a response the IRS will accept. Those calls decide whether the notice goes away or grows. So we handle that part ourselves: we reconstruct the history, establish what you actually owe, and prepare the reply. Then Koinly runs the numbers. If you already have a Koinly portfolio, we can work directly from it.

CountDefi did a great job at reconciliation and I recommended them for their dedication to detail. The IRS schedule forms they provided in their reports were pivotal to filing my taxes smoothly.

Given the complex nature of cryptocurrency transactions, calculating taxes is extremely difficult. This has been a major problem for me in previous years and CountDeFI is a life changing solution for me! The entire process is extremely surprisingly smooth.

Frequently asked questions
Can CountDeFi help with an IRS crypto audit?
How much does IRS crypto audit support cost?
Yes. CountDeFi provides specialist IRS crypto audit support for investors whose cryptocurrency transactions, cost basis or tax reporting are being examined. We reconstruct the transaction history, reconcile exchanges and wallets, calculate the correct tax position and prepare the supporting crypto accounting records needed for the examination. We can also work with your CPA, tax attorney or other authorised representative where required.
CountDeFi prices crypto accounting work according to transaction volume and complexity rather than open-ended hourly billing. The amount of work required depends on the size of the portfolio, number of tax years involved, quality of the existing records and the issues raised by the IRS. Our published crypto accounting plans start at $695 for up to 500 transactions, with Standard at $1,695 for up to 3,000, Premium at $2,995 for up to 5,000, Expert at $4,495 for up to 10,000, and Degen at $5,995 for up to 15,000 transactions. An IRS audit or notice may require additional work depending on its scope, so we confirm the appropriate engagement before starting. See our Pricing page for more.
I received a CP2000 or IRS letter about crypto. What should I do?
Can CountDeFi help if my existing crypto tax reports are wrong?
Start by checking what the IRS is actually questioning before agreeing with the amount shown. A crypto notice can arise because information reported to the IRS does not match your return, cost basis is missing, or transactions have been reported without enough context. CountDeFi can review the notice, reconcile the underlying crypto activity and prepare the calculations and supporting records needed to respond. Do not ignore the response deadline shown on the notice.
Yes. An IRS examination sometimes exposes problems that began with the original crypto accounting rather than the tax return itself. Missing transactions, incorrect cost basis, unmatched wallet transfers, duplicate imports and misclassified DeFi activity can all affect the reported figures. CountDeFi can review the existing accounting, reconstruct the portfolio where necessary and produce corrected calculations and supporting records. We can work from an existing Koinly, CoinTracking or other crypto tax software portfolio where the underlying data is usable.
Why does the IRS say I owe much more crypto tax than I expected?
Can CountDeFi work with my CPA or tax attorney during an IRS crypto audit?
One common reason is missing cost basis. If the IRS has proceeds information for a crypto disposal but does not have the corresponding acquisition cost, the apparent taxable gain can be much higher than the real gain. Other problems can include transfers between your own wallets being misread, incomplete exchange records or transactions being classified incorrectly. Our IRS crypto audit support starts by rebuilding the underlying accounting so the figures can be checked against what was originally reported.
Yes. You do not need to replace your existing CPA or tax attorney to use CountDeFi's IRS crypto audit support services. We can handle the specialist crypto accounting behind the examination while your existing adviser manages the wider tax matter or formal IRS representation. We provide the reconciled transaction history, cost basis calculations, tax reports and supporting records they need to understand and defend the crypto figures. If you do have an existing CPA or attorney, we can work with them too.
Can CountDeFi reconstruct missing cost basis for an IRS crypto audit?
Does CountDeFi provide IRS crypto audit support for DeFi and complex portfolios?
Yes. Cost basis reconstruction is a core part of our IRS crypto audit support. We can trace acquisition and disposal history across exchanges, self-custody wallets and blockchains to establish cost basis where the available evidence allows it. This is particularly important when the IRS has transaction or proceeds data but your original tax return did not contain complete basis information. Rather than estimating the answer, we rebuild the transaction history and document the calculations supporting the corrected position.
Yes. CountDeFi specialises in complex crypto accounting involving DeFi, staking, lending, NFTs, crypto mining, derivatives, prediction markets, self-custody wallets and multi-chain activity. These portfolios can be difficult to explain during an IRS examination because blockchain records show transactions without necessarily showing their tax meaning. We reconstruct crypto activity and apply the relevant tax treatment before producing the supporting accounting records.
I haven't filed crypto taxes for some years. Can CountDeFi help me catch up?
Can CountDeFi handle my ongoing crypto tax reporting after an IRS audit?
Yes. As specialised crypto tax accountants we can reconstruct historical crypto activity across multiple tax years, calculate gains, losses and income, and prepare the crypto tax reports needed to bring your IRS records up to date. Earlier years often need to be dealt with in sequence because the cost basis of crypto sold today may originate with an acquisition several years ago. CountDeFi can rebuild that history before preparing the relevant reporting for your CPA or tax professional.
Yes. Once the historical records have been reconciled, CountDeFi can continue handling your annual crypto tax accounting and reporting. This can be particularly useful after an audit or IRS notice because the corrected cost basis and transaction history can be carried forward rather than allowing the same problems to reappear in the next tax year. We can handle the complete crypto accounting engagement or provide the finished calculations and reports to your existing CPA.
What does a crypto tax audit accountant do?
Where can I get IRS crypto audit help?
A crypto tax audit accountant rebuilds the transaction history behind the year under examination, matches it to what the IRS holds from exchanges and brokers, documents cost basis for every disposal and prepares the schedules and written response. CountDeFi does that work. Your CPA, enrolled agent or tax attorney represents you before the IRS.

We reconstruct the records, work out what you actually owe and prepare the response package for you or your representative. Contact us as soon as the letter arrives. IRS notices carry a fixed response deadline.
