A federal tax refund suit is a lawsuit brought against the Internal Revenue Service and the United States to recover taxes, penalties, or interest that were wrongfully or illegally collected. These cases are typically used when the IRS has denied a refund claim, failed to act on it, or refused to correct an improper assessment through administrative channels.
Before a refund suit may be filed, the taxpayer must generally pay the disputed tax and submit a formal refund claim to the IRS. That claim must clearly state the legal and factual basis for the refund. If the IRS denies the claim—or does not act within the required time—the taxpayer may proceed to federal court.
Refund suits are filed in either the United States District Court or the U.S. Court of Federal Claims, depending on jurisdictional and strategic considerations. These cases are decided by federal judges and involve formal litigation procedures, including legal briefing, discovery, and evidentiary presentation.
Refund suits are often used to challenge:
A refund suit forces the IRS to defend its position in court and places the dispute before an independent federal judge. For taxpayers facing substantial exposure or entrenched IRS positions, refund litigation can be the most effective way to obtain meaningful review and recovery.
Whether a refund suit is viable depends on strict procedural rules, jurisdictional requirements, and timing considerations. A tax attorney evaluates these factors before litigation begins, as missteps can permanently bar relief.
“ 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.”
