The mismatch

Why crypto holders get flagged.

The IRS may see proceeds or income without the cost basis and transfer history needed to calculate the actual tax. A notice often begins in that gap. The same mismatch can drive a CP2000 or become an issue in an IRS crypto audit, so the record has to be rebuilt and explained.

Common Crypto IRS Notices We Help Resolve

Crypto IRS notices do not carry the same deadline or response requirement. Choose the number printed on your letter to see what it means, what date controls, whether a reply is required, and the records that typically resolve the mismatch.

CP2000

What is a crypto CP2000 notice and how do I respond?

A CP2000 is a proposed change, not a bill or a formal audit notice. It usually means information reported to the IRS does not match the return. Respond within 30 days of the notice date, or 60 days if you live outside the United States, and state whether you agree or disagree. Effective crypto CP2000 help often requires a transaction reconciliation that replaces gross-proceeds-only assumptions with documented cost basis.

IRS Matching Data

What information does the IRS receive about crypto?

The IRS can compare broker forms, other information returns, third-party exchange records, and the taxpayer's own return. Those sources may identify a mismatch, but they do not determine the correct tax without supported basis, transfer tracing, and the right classification of ordinary income.

1099-DA

Broker sales

Gross proceeds for covered transactions beginning in 2025. Basis reporting phases in for certain transactions beginning in 2026.

1099-B / MISC

Other sales and income

Information returns can report proceeds or ordinary income that the IRS compares with the filed return.

1040

Your own answer

Every filer answers the digital asset question. A Yes answer does not report the underlying transactions.

SUMMONS

Third-party records

Court-approved John Doe summonses can provide exchange activity and identifying information.

Crypto Tax Audit

How does a crypto tax audit work?

A crypto tax audit starts when the IRS selects issues on a filed return and asks for records supporting the reported amounts. The response connects exchange data, wallet activity, and reconstructed cost basis to the forms under review. A CPA can communicate under Form 2848, organize the production, explain tax positions, and protect response or appeal deadlines.

RIGHTS PRESERVED
Our Process

Four steps to resolution.

A defensible response starts with the deadline, then connects the filed return to complete transaction evidence. Each stage creates a named output, so the work moves from letter to ledger to response without treating every notice like a full audit.

Notice, amount, issuing unit, and every date are logged before drafting.

What not to do

Three moves that make a crypto notice harder.

Do not call the IRS unprepared, amend the return blindly, or send raw exchange files without a reconciled ledger and explanation.

Response control memo
Hold before sending
01
Uncontrolled instinct

Call the IRS unprepared

What it costsSpeculating about unreconciled transactions can create a second problem before the first one is understood.
Do this insteadLog the notice, response date, tax year, and amount. Reconcile the transactions before discussing facts or figures.
02
Uncontrolled instinct

Amend the return blindly

What it costsA CP2000 response often follows a different process. An unnecessary amendment can complicate the record.
Do this insteadFollow the notice response path first. Amend only when the reconciled record and procedure show a correction is required.
03
Uncontrolled instinct

Send raw exchange CSVs

What it costsUnexplained files do not connect wallet transfers, basis, proceeds, and tax treatment to the amount under review.
Do this insteadSend a reconciled ledger, schedules, and a concise explanation that ties each exhibit to the disputed amount.
Licensed review chain

The response passes through two licensed checkpoints.

Garrett leads the notice position, deadline plan, and authorized IRS communication. Leanne reviews the supporting record and checks that any correction remains consistent with the reconciled ledger. This named review chain is part of our crypto CPA services for complex digital asset matters, with both credentials independently verifiable.

Record Reconstruction

Rebuilding the Records Behind an IRS Notice

Many notices begin with an incomplete history. We use Digital Asset Reconciliation to trace transfers, rebuild basis under FIFO, LIFO, HIFO, or specific identification where supported, and connect the corrected ledger to the notice. If a filing must change, tax return preparation keeps the amended return consistent with the response.

Who It Is For

Sound like your situation?

Open the route that matches where you are now. Each starts with a different problem, but all require the same discipline: preserve the date, rebuild the record, and answer only with supported facts. The route then shows the evidence and response path that fit that stage.

01The First-Time FilerCP2000 mismatchRebuild the missing historyRespond with supported basis

You received a CP2000 for unreported crypto transactions. The rules were unclear or an information form arrived later. The job is to explain the mismatch accurately, not assume gross proceeds equal taxable gain.

02The Delinquent TaxpayerMultiple unfiled yearsMap every platform and yearReturn to compliance

You have unfiled years with trading, staking, NFTs, or DeFi. Notices have started, and you need one structured record that keeps each year and correction consistent.

03The Audit TargetExamination or IDRProduce indexed evidenceResolve or preserve appeal rights

The IRS wants support for trades, transfers, basis, and DeFi positions. You need a representative who can connect source records to each issue under review.

Response Timing

Responding Before IRS Deadlines Expire

The safest deadline is the date printed on the notice. Start reconstruction immediately if records are incomplete, and follow the letter's instructions if an extension request is available. Missing a date can turn an information request into an assessment, collection action, or lost appeal right.

30 DAYS

Generally from the notice date. 60 days if you live outside the United States.

Response Checklist

What should I gather for a crypto IRS notice response?

Start with the full notice, the return under review, every information form, and complete transaction records for the relevant years. Preserve raw exports before changing files. Then build a reconciliation that explains transfers, basis, disposals, and ordinary income. Send only organized records that answer the IRS request.

IRS Notice FAQ

Common questions.

Each answer is visible in full so you can scan the issue without opening an accordion.

Q01What types of IRS notices do you handle for crypto?

We handle CP2000 and CP2501 underreporter matters, Letters 6173, 6174, and 6174-A, examination notices, and collections notices involving digital assets.

Q02How quickly do I need to respond to an IRS notice?

The deadline is printed on the notice and varies by notice type. Review it immediately so records can be gathered and a complete response prepared before the deadline.

Q03Can you get penalties reduced or removed?

Penalty abatement may be available through reasonable cause, first-time abatement, or other statutory provisions. Eligibility depends on the facts and supporting documentation.

Q04What happens if I get selected for a full audit?

With a valid Form 2848, we can represent you before the IRS, organize the supporting records, handle correspondence, and attend meetings within the scope of our authorization.

Q05Should I consider voluntary disclosure if I have unreported crypto?

That decision depends on the amount, years involved, conduct, and whether the IRS has already contacted you. We evaluate the available compliance paths before recommending a response.

Q06Will the IRS always accept the cost basis I reconstruct after receiving a notice?

Not automatically. Reconstructed basis should be supported by blockchain records, exchange histories, pricing data, and transfer documentation that explains how each figure was calculated.

Q07Should I respond to an IRS crypto notice before gathering all of my records?

Review the notice immediately, but a substantive response should generally address the issue with complete supporting documentation when the deadline allows. An incomplete response can make resolution harder.

Q08Does a CP2000 mean I am being audited?

No. A CP2000 is an automated underreporter notice proposing changes because third-party information does not match the return. It is not a formal audit notice. You should still respond by the deadline because an unresolved CP2000 can lead to a statutory notice of deficiency.

Q09Can a CPA represent me in a crypto tax audit?

Yes. A CPA who is eligible to practice before the IRS can represent you within the authority granted on Form 2848. The CPA can communicate with the examiner, organize records, prepare explanations, and attend meetings, while some documents may still require your signature.

Q10What penalties apply to unreported crypto?

The result depends on why the income or gain was omitted. Tax, interest, and an accuracy-related penalty may apply, and late filing or late payment penalties may also apply. More serious conduct can carry additional civil or criminal consequences. Penalty relief depends on the facts, filing history, and supporting evidence.

Q11How long does a crypto IRS notice take to resolve?

There is no fixed resolution time. A documented information-matching response may take several months, while an examination involving missing records, multiple tax years, or disputed positions can take longer. The immediate priority is preserving the response and appeal deadlines even when the IRS review continues beyond them.
