Unfiled Tax Returns
Unfiled Tax Returns
Last updated November 5, 2026
When tax returns remain unfiled, the IRS may prepare a Substitute for Return based on income reported by employers and financial institutions. That assessment does not include deductions, exemptions, or credits you may claim, so it is often significantly higher than what you owe. Collection efforts, penalties, and interest can follow, and in most cases six years must be filed.
Failing to file tax returns can quickly turn into a serious problem. The IRS does not forget about missing returns. The longer they remain unfiled, the greater the financial and legal consequences may become.
Many individuals and business owners fall behind due to financial hardship, disorganization, illness, or overwhelming tax balances. Regardless of the reason, unfiled returns can trigger substitute returns by the IRS, aggressive collection actions, and escalating penalties.
Bringing your filings current is often the first and most important step toward resolving tax debt.
What Happens If You Don’t File?
When a required tax return is not filed, the IRS may prepare a Substitute for Return (SFR) for you. An SFR is based on income that employers and financial institutions reported to the IRS. It does not include deductions, exemptions, or credits you may be entitled to claim.
As a result, the tax assessed through an SFR is often significantly higher than what you may actually owe.
Once the IRS assesses the balance, it can begin collection efforts such as:
- Wage garnishments
- Bank levies
- Federal tax liens
- Seizure of refunds
- Ongoing penalties and interest
Unfiled returns also prevent you from entering into most IRS resolution programs. The IRS generally requires full filing compliance before approving installment agreements or settlement options.
Penalties for Failure to File
The failure-to-file penalty is typically more severe than the failure-to-pay penalty. It accrues monthly and can reach up to 25% of the unpaid tax balance. Interest also continues to accumulate on both the tax and penalties.
In more serious cases, prolonged non-filing may expose a taxpayer to potential criminal investigation, particularly if there is evidence of willful avoidance.
Addressing unfiled returns proactively reduces these risks and demonstrates good-faith compliance.
How Many Years Must Be Filed?
In most cases, the IRS requires the last six years of tax returns to be filed to restore compliance. Still, each situation is different. The exact number of required filings depends on your income history. It also depends on prior IRS assessments. It depends, too, on whether substitute returns were prepared.
Obtaining and reviewing IRS transcripts is often necessary to determine what is missing and what has already been assessed.
Bringing Your Tax Record Current
Resolving unfiled returns involves more than simply submitting paperwork. A strategic approach may include:
- Securing wage and income transcripts from the IRS
- Identifying deductions and credits that reduce liability
- Replacing inaccurate Substitute for Returns
- Coordinating filings to minimize collection exposure
- Developing a resolution plan for any resulting balance
Filing returns that are properly prepared can greatly lower assessed balances. It can also open the door to structured payment arrangements or settlement options.

TESTIMONIALS
“ Andrew Margolies did a great job for my mom who had paid her taxes, but the IRS failed to associate the payment with her account. She kept getting letters demanding payment with accrued interest and fees even though they had cashed her check.
After Andrew started working on it, the letters stopped. We were notified there had been a credit to my mom’s account, and finally the payment was properly applied with a zero balance. She is even receiving a refund.
We’re very happy with Andrew and would highly recommend him.”

“I came to Andrew Margolies with a significant IRS issue that I had been losing sleep over for months. I spoke with Jennifer on the phone, got in the same day for a consultation, and had a full resolution within 2 business days for a reasonable price. Andrew did exactly what he said he was going to do and provided me with a thorough resolution.
Being 9 months pregnant, Andrew was extremely sensitive to my timeline urgency and was on the phone with me at 5pm on a Friday helping me with my case.
Before meeting with Andrew, I called around to 10 different offices. All of those interactions felt like a sales funnel and a money grab. I can’t explain the relief I have having chosen to work with Andrew and having a resolution within days. We’re absolutely thrilled with the value and the experience.”

“100% recommended. I had a problem regarding my tax return since the beginning of 2023 and had been trying to follow up myself until 2025 with no progress. I decided to work with Attorney Andrew and Jennifer and in less than a month my problem was solved.
Attorney Andrew is very knowledgeable with reasonable fees and Jennifer is very responsive to all requests and questions. Most importantly they have business ethics. I will not look further if I have any more tax problems.”
