Haven't Filed Taxes in Years? How to Get Back on Track
What happens when returns go unfiled, how far back you usually need to go, and how to catch up step by step.

Falling behind on tax returns happens more often than people think. A business struggles, a family member gets sick, or one missed year turns into three. The longer it goes, the harder it feels to start. Here is the path back.
What happens when you don’t file
- Penalties grow every month. The failure-to-file penalty is generally 5% of the unpaid tax for each month a return is late, up to 25%. A separate failure-to-pay penalty and interest are added on top.
- The IRS may file for you. It can prepare a “substitute for return” using only the income it knows about, without your deductions or credits, which usually means a higher bill.
- You can lose refunds. If you were owed a refund, you generally have three years from the original due date to claim it.
- California acts too. The Franchise Tax Board can issue its own estimated assessments for unfiled state returns.
How far back do you need to go?
In many cases, the IRS asks for the last six years of returns to consider you back in good standing. The right number depends on your situation, so it is worth confirming before you start.
Step-by-step: getting current
- Get your IRS transcripts. Wage and income transcripts show the W-2s and 1099s the IRS has on file for each year. You can request them online through Get Transcript.
- Gather what you have. Bank statements, receipts, and business records help support deductions the IRS doesn’t know about.
- File the missing returns. Filing stops the failure-to-file penalty from growing for that year and often lowers the balance compared to an IRS substitute return.
- Deal with any balance. Options include payment plans, penalty relief such as first-time abatement, and in some cases an offer in compromise.
- Stay current. Set up withholding or quarterly estimated payments so the problem doesn’t come back.

Common questions
Will I get in trouble for filing late?
Filing late usually means penalties and interest, not criminal charges. Coming forward and filing is the best way to limit the damage.
Do I need all my receipts to file past-due returns?
Not always. Transcripts, bank statements, and other records can be used to rebuild income and expenses.
Can you help with unfiled California returns too?
Yes. We help clients file past-due returns with both the IRS and the Franchise Tax Board.
