What should I do about unfiled tax returns from past years?

First, do not panic — but do act

Unfiled returns get worse with time because penalties and interest accrue, and because the IRS can eventually file a return for you that leaves out your deductions. The good news is that the path forward is routine, and most people have far more of the information they need than they think.

Step 1: Figure out which years are missing

List the years you did not file. If you are not sure, an IRS account transcript for each year shows whether a return was processed and what the IRS has done on the account.

Step 2: Pull your transcripts

Two transcripts do most of the work:

• Wage and income transcript — shows W-2s, 1099s, and other income statements reported to the IRS under your SSN for that year. This lets you reconstruct income even if you lost the paperwork.
• Account transcript — shows filings, payments, penalties, and whether the IRS filed a Substitute for Return.

Bank statements and, for gig workers, the app annual summaries fill in anything the transcripts miss (transcripts often lag the most recent year or two).

Step 3: Prepare the returns in order

Prepare the oldest missing year first and work forward. Numbers move between years — capital loss carryovers, prior-year estimated payments, net operating losses, and prior balances — so doing them out of order produces wrong results.

Each missing year needs an original return for that year, on that year's forms and rules. A year that was filed but is wrong needs a Form 1040-X amendment instead.

Step 4: Deal with a substitute return

If the IRS filed a Substitute for Return, it used only the income it had and gave you no deductions, no dependents, and the least favorable filing status, then billed you. Filing your own accurate return for that year usually lowers the amount owed, sometimes substantially.

Step 5: Handle the balance

File even if you cannot pay. Filing on time (or as soon as possible) stops the failure-to-file penalty, which is much larger than the failure-to-pay penalty. Once the returns are in, the IRS offers payment options: short-term plans, monthly installment agreements, and in limited cases an Offer in Compromise. Ross can explain which may fit and prepare the request forms for you to submit.

How far back do you have to go?

There is no limit on preparing old returns, but the IRS generally considers the last six years enough to treat someone as compliant. A refund can usually only be claimed within three years of the original due date — after that the refund is lost, though filing still matters to close out the year.
