The IRS operates under time limits. They cannot audit you forever or collect from you indefinitely. Understanding these statutes of limitations — and the exceptions that extend them — is critical for any crypto taxpayer with current or potential IRS issues.

Assessment Statute (ASED)

The IRS generally has three years from the date you filed your return to assess additional tax. If you filed your 2021 return on April 15, 2022, the IRS must assess any additional tax by April 15, 2025. After that date, the year is closed — they cannot go back and add more tax. This is the Assessment Statute Expiration Date (ASED).

Six-Year Extension

If you omitted more than 25% of gross income from your return, the statute extends to six years. For crypto taxpayers who failed to report significant gains, this extension applies. If you reported $100,000 in total income but actually had $200,000 (with $100,000 in unreported crypto gains), the six-year statute applies because the omission exceeds 25% of reported gross income.

No Statute for Fraud or Non-Filing

There is no statute of limitations for fraudulent returns or for years in which no return was filed. If you filed a return that fraudulently omitted crypto income, the IRS can assess additional tax at any time — forever. If you did not file a return at all, the statute never starts running. This is why filing — even if late — is always better than not filing.

Collection Statute (CSED)

Once the IRS assesses a tax, they have 10 years to collect it. This is the Collection Statute Expiration Date (CSED). After 10 years, the debt is legally extinguished — the IRS cannot collect and the debt disappears. However, certain actions toll (pause) the CSED: filing an OIC, filing bankruptcy, requesting a CDP hearing, and living outside the United States. Each tolling event extends the 10-year period.

Strategic Implications

Knowing your ASED and CSED dates is essential for making informed decisions about how to resolve crypto tax problems. In some cases, running out the CSED through CNC status is more advantageous than an OIC. In other cases, the six-year ASED means the IRS has more time to audit than you expected. Attorney Darrin T.
