Most taxpayers assume that – if they disagree with the IRS – they can simply take the dispute to court. In some situations, that assumption is correct. The US Tax Court allows taxpayers to challenge certain IRS determinations before paying the disputed tax.
But that option is not always available. In many tax disputes, the law requires the taxpayer to pay the tax first and litigate later. These cases are known as refund suits. They are filed in either the US District Court or the US Court of Federal Claims, and they follow a very different procedural path than US Tax Court litigation.
For taxpayers who discover that the US Tax Court deadline has passed—or whose disputes arise after tax has already been assessed—the refund suit process may become one of the many ways to challenge the IRS’s determination.

The Full Payment Rule
One of the most important aspects of refund litigation is the full payment rule. In Flora v. United States, 357 U.S. 63 (1958), the US Supreme Court ruled that taxpayers must pay the entire assessed tax liability before filing a refund suit. This principle is often referred to as the “pay first, litigate later” rule. Certain exceptions, however, exists. Understanding whether the full payment rule applies is critical to evaluating refund litigation options.

The Administrative Refund Claim Requirement
Before filing a refund lawsuit, taxpayers must first submit an administrative refund claim to the IRS. Specifically, section 7422 requires taxpayers to file a formal administrative claim for a refund with the IRS before they file a lawsuit in either the US District Court or the US Court of Federal Claims. This requirement is critical. The US District Court or the US Court of Federal Claims may not hear refund cases unless the taxpayer has met this requirement.
Once the administrative refund claim is filed, the IRS may review it, request additional information, or deny the claim. If the IRS denies the claim—or fails to act within the statutory period—the taxpayer may proceed to court.

The Two Federal Courts That Hear Refund Suits
Refund litigation may be filed in one of two federal courts. Section 1346(a)(1) grants Federal District Courts, concurrently with the US Court of Federal Claims, original jurisdiction over civil actions against the United States for the recovery of erroneously or illegally assessed or collected internal revenue taxes, penalties, or sums.
1️⃣ US District Court
The US District Court is the federal trial court located in each judicial district across the country. Cases filed here may be heard by a judge and, in some circumstances, by a jury.
2️⃣ US Court of Federal Claims
The US Court of Federal Claims is a specialized court in Washington, D.C. that hears monetary claims against the federal government.

Differences Between US Tax Court and Refund Litigation
The most significant difference is timing of payment. The US Tax Court allows disputes before paying the tax, while refund suits in either the US District Court or the US Court of Federal Claims require payment first.
Another difference is the government’s representation. In US Tax Court cases, the IRS Office of Chief Counsel represents the government. In refund litigation in either the US District Court or the US Court of Federal Claims, the Department of Justice handles the defense.
These distinctions can affect negotiation dynamics and litigation strategy.
When to Hire a Tax Litigation Attorney?
Refund litigation is federal court litigation. Procedural rules, evidentiary standards, and legal strategy differ significantly from audit-stage discussions with the IRS. An experienced tax litigation attorney can evaluate whether refund litigation is appropriate, assess the strength of potential claims, and determine the best forum for filing suit. Legal counsel also ensures compliance with strict procedural requirements that govern refund claims and federal court filings.
