Behind on filing or owe back taxes? Your options, in order

Unfiled returns tend to snowball. One year gets skipped because the books weren't ready, then the next year feels impossible without the first. Meanwhile penalties and interest grow quietly. The way out is more straightforward than most people expect — and it starts with filing, not paying.

Step one: file, even if you can't pay

Two separate penalties apply when you're late:

• Failure to file: 5% of the unpaid tax for each month or partial month the return is late, up to 25%. If the return is more than 60 days late, a minimum penalty applies.
• Failure to pay: 0.5% of the unpaid tax per month, up to 25%. The rate drops to 0.25% per month while an approved installment agreement is in place.

Filing stops the larger penalty immediately. Even if you can't pay a dollar, filing on time — or as soon as possible — is the single most valuable move.

If you don't file, the IRS may eventually file a substitute for return for you. It uses the income reported to it and none of your deductions, so the resulting bill is usually much higher than your real liability. You can still file your own return to replace it.

And if you're owed a refund for an old year, don't wait: you generally lose the right to claim a refund three years after the original due date.

How penalties and interest add up

Interest accrues on unpaid tax from the original due date, and on most penalties too, compounding daily at a rate the IRS sets each quarter (the federal short-term rate plus 3 percentage points). Unlike penalties, interest generally can't be waived. That's why getting a payment plan in place quickly matters, even if the monthly amount is small.

Your payment options

An offer in compromise is often advertised as a way to "settle for pennies on the dollar." In practice, the IRS calculates what it believes it can collect from your assets and future income, and accepts offers only when that figure is less than what you owe. Many people who apply don't qualify. It's worth an honest evaluation before paying for an application.

Reducing the penalties

First-time abatement is an administrative waiver of failure-to-file, failure-to-pay and failure-to-deposit penalties for one tax year, available if you have a clean penalty history for the previous three years and you've filed all currently required returns (or have valid extensions). It's often granted over the phone or by letter.

Reasonable cause relief is available if you can show you acted with ordinary care and still couldn't comply — for example, serious illness, a disaster, or being unable to obtain records. It requires a written explanation with support.

A realistic plan for getting current

1. Request your IRS transcripts for the missing years. They show the income reported to the IRS and any payments or notices on file.
2. Rebuild the books from bank and card statements for each year.
3. Prioritize. The IRS generally expects the most recent six years to be filed to consider you in good standing, and returns showing refunds may have a closing window.
4. Get this year right — file on time and make estimated payments, so the problem doesn't grow while you fix the past.
5. Set up a payment plan and request abatement once the returns are in.

States have their own penalties and payment plans, and they share information with the IRS, so include state returns in the plan. We handle catch-up engagements regularly — without judgment, and with the aim of getting you to a single, predictable monthly payment.
