What happens if I have unfiled tax returns?

Updated October 8, 20262 sourcesTaxTruce teamFact checked
The short answer

The IRS may file a substitute return for you, which can miss deductions. That leads to a tax bill and, if unpaid, liens and levies. Penalties grow while you wait. People who repeatedly don't file can face more penalties and criminal prosecution.

Filing your own return is still better, even after a substitute return.
