Unfiled returns are a solvable problem — and the solution is almost always better than the fear. The IRS generally looks for the last six years of returns to consider a non-filer back in compliance, and filing before the IRS finds you preserves options that disappear afterward.

What happens if you do not file
The IRS can prepare a substitute for return on your behalf under IRC § 6020(b) — using only the income it knows about, with none of your deductions, exemptions, or basis. The resulting assessment is nearly always worse than what you would owe on a real return, and it starts the collection process on inflated numbers. The failure-to-file penalty runs 5% per month up to 25%, on top of failure-to-pay and interest.
The path back
Reconstruct the records, file the missing years — accurately, in the right order — and resolve the resulting balance through the normal tools: installment agreements, penalty relief where the facts support it, and offers in compromise where the numbers do. If a substitute return has already been filed, an original return can generally replace its inflated assessment.
What we do
We pull your IRS transcripts to see exactly what the IRS knows, reconstruct the years that need filing, and manage the sequence so compliance does not trigger enforcement. Fees quoted upfront, hourly or flat-fee.
