A Tax Court case allows a taxpayer to challenge an IRS determination without paying the disputed tax first. For many disputes, it is the primary judicial forum for resolving tax issues before collection occurs.
The United States Tax Court is a specialized federal court that hears disputes between taxpayers and the Internal Revenue Service. Its judges focus exclusively on federal tax law, making it a central venue for litigating complex tax matters.
Most Tax Court cases begin after the IRS issues a Notice of Deficiency (commonly called a “90-day letter”). The taxpayer must file a petition within the statutory deadline, typically 90 days, or the right to challenge the assessment in Tax Court is lost.
Other matters, such as certain collection disputes, may also be eligible for Tax Court review depending on the notice issued.
Taxpayers can litigate without first paying the tax, penalties, or interest in dispute.
Cases are decided by judges experienced in federal tax law.
Cases may proceed under regular rules or, for smaller disputes, simplified procedures.
Trials are held in locations across the country, reducing logistical burden.
Tax Court cases often involve:
Tax Court litigation can halt IRS collection activity and place the dispute before an independent judicial forum before payment is required. For many taxpayers, it is the most practical and cost-effective way to challenge an IRS position.
Choosing the correct forum, meeting statutory deadlines, and developing the evidentiary record are critical. A tax attorney evaluates these factors early, as missed deadlines or procedural errors can eliminate the ability to contest the assessment.
“ 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.”
