- Some IRS crypto audits now request disclosure of every wallet and exchange used
- Taxpayers must confirm activity across platforms under penalty of perjury
- New reporting rules like Form 1099-DA give the IRS deeper visibility into crypto trading
The IRS is tightening its grip on cryptocurrency taxation, and recent audit practices suggest the agency is becoming far more aggressive in tracking digital asset activity. According to reports shared among tax professionals, some crypto investors under audit are now receiving detailed questionnaires asking them to disclose every exchange and wallet they have ever used.
The documents reportedly include long lists of platforms, ranging from major centralized exchanges to hardware wallets and decentralized services. Taxpayers are asked to mark “yes” or “no” next to each platform and then sign the form confirming their answers are accurate under penalty of perjury.
Audits Now Demand a Full Crypto Activity Map
For many investors, the questionnaire effectively demands a full record of their crypto history. Traders who have moved funds across multiple exchanges, wallets, and DeFi platforms over several years could face significant challenges reconstructing their activity.
Tax attorneys warn that signing such documents without verifying every detail can create serious legal risks. If any information is missing or incorrect, the signed statement could expose taxpayers to further penalties or enforcement actions.
Because blockchain transactions can be traced publicly, the IRS may already have partial records that it can compare against the disclosures provided in these questionnaires.
The IRS Already Has More Crypto Data Than Expected
The new audit approach comes as the IRS expands its ability to track digital asset transactions. Beginning with the 2025 tax year, U.S. crypto brokers must issue Form 1099-DA, a reporting document that sends transaction data directly to both taxpayers and the IRS.
The form will include details such as proceeds from digital asset sales, allowing the IRS to compare exchange records with individual tax filings. This reporting framework significantly increases the agency’s visibility into crypto trading activity.
Over the past several years, the IRS has also gathered records from exchanges through legal subpoenas and regulatory data requests, building a growing database linking wallet activity to verified identities.
Why Crypto Audits Are Becoming More Aggressive
From the IRS perspective, cryptocurrency created a major reporting gap within the tax system. Unlike traditional brokerage accounts, crypto trading often occurs across multiple platforms and self-custody wallets without standardized reporting.
The new audit questionnaires appear designed to close that gap. By requiring taxpayers to identify every platform they have used, investigators can combine those disclosures with exchange records and blockchain analytics.
Once those data points are connected, the IRS can reconstruct transaction histories and verify whether gains or losses were reported correctly on tax returns.
Crypto Tax Enforcement Is Entering a New Phase
For years, many crypto traders assumed that spreading transactions across multiple wallets or exchanges made oversight difficult. That assumption is becoming outdated.
With exchange reporting requirements expanding and audit procedures becoming more detailed, regulators are steadily building the infrastructure needed to track digital asset activity more closely.
Tax professionals say anyone facing a crypto-related audit request should review their records carefully before signing any statements. As enforcement tools grow more sophisticated, accuracy and documentation are becoming increasingly important for crypto investors navigating the U.S. tax system.
