Haven't filed in years? Start here.
The IRS does not forget a missing return. It writes one for you, and it is never in your favor. These guides explain how many years you need to file, how a substitute for return works, how to rebuild missing records, and where the criminal line actually is.
The non-filer's first-week checklist
- Stop guessing. Find out which years the IRS shows as unfiled.
- Pull wage and income transcripts for every missing year.
- Read every IRS letter and note any 30-day or 90-day deadline.
- Gather bank statements to rebuild income and expenses.
- Talk to a tax attorney before you talk to an IRS agent.
How a non-filer case usually unfolds
Every case is different, but the IRS follows written procedures. Knowing the sequence tells you how much time you have.
Notices
The IRS matches W-2s and 1099s against filed returns and sends notices asking for the missing ones.
Substitute for return
If you do not file, the IRS can prepare a return from third-party data under IRC 6020(b).
90-day letter
A statutory notice of deficiency gives you 90 days to file or petition the Tax Court.
Assessment and collection
Once the tax is assessed, liens and levies become possible. Filing your own returns is still the fix.
