Businesses and individuals who paid taxes with no legal basis are entitled to a refund, but few know how to get back what they overpaid. Identifying the undue payment, choosing between offsetting and a cash refund, and meeting the five-year deadline determine whether you recover your money.

How to identify an undue payment

Every recovery starts with recognizing that a payment had no legal basis. Article 165 of Brazil’s National Tax Code (Código Tributário Nacional) guarantees a full or partial refund of a tax whenever the charge was undue or excessive, regardless of whether the taxpayer first objected.

The reasons vary. There may be a calculation error, the wrong rate may have been applied, amounts that should not have been in the tax base may have been included, or a tax may have been paid and later declared unconstitutional. Duplicate payments and withholding at source above what was owed also count.

For a business, the review usually begins with the tax records of the past five years. You compare the payments actually made against what the law required in each tax period. Recurring discrepancies point to an accumulated credit that can be recovered, as long as it is precisely documented.

For individuals, the most common cases involve income tax withheld beyond what was owed, social security contributions on amounts that are compensatory in nature, and municipal taxes assessed on a property whose size or use was recorded incorrectly. In every one of these cases, the proof of payment is the key evidence of your right.

The administrative route: refund requests and electronic offsetting

The administrative route is generally the fastest and least costly. At the federal level, the taxpayer files the request directly with the Receita Federal (Brazil’s federal tax authority) through the program for Refund, Reimbursement and Offset Declaration Requests, an electronic system that brings together the request and the supporting documents.

At this stage, you demonstrate the origin of the credit, state the amount updated by the Selic rate (Brazil’s benchmark interest rate), and choose between receiving cash or offsetting the credit against your own debts. The tax authority reviews the request and may approve the offset expressly or by default, when the legal deadline passes without a response.

States and municipalities have their own procedures, almost always started by filing a request with the competent treasury department. The forms differ, but the logic is the same: prove the payment, state the grounds for the refund, and request either a refund or an offset of the amount calculated.

The advantage of the administrative route is that it avoids the cost and delay of a lawsuit. Its limit appears when the tax authorities refuse to recognize the undue payment, especially in claims that depend on a declaration of unconstitutionality or on a disputed interpretation of the law.

If the request is denied, you can still appeal within the administrative tax tribunals before taking the dispute to the courts. This appeal preserves the deadline and organizes the arguments that will serve, if necessary, in the next stage.

There may be a calculation error, the wrong rate may have been applied, amounts that should not have been in the tax base may have been included, or a tax may have been paid and later declared unconstitutional.

The judicial route: the action for recovery of undue payments

When the administrative solution is exhausted or proves unworkable, recovery proceeds through the action for recovery of undue payments (ação de repetição de indébito). This is the classic tool for getting back, through the courts, taxes that were paid improperly, with inflation adjustment and interest from the date of payment.

In this action, the taxpayer asks the court to order the public entity to return the amount. Once the right is recognized by a final judgment, payment is made through a precatório (a court-ordered payment owed by the government, paid in a queue) or through a small-value payment requisition, depending on the amount and the debtor entity.

In Súmula 461 (the court’s summary of its settled case law), the Superior Court of Justice (Superior Tribunal de Justiça) established that the taxpayer may choose whether to collect an undue payment, recognized by a final declaratory judgment, through a precatório or through offsetting. This freedom of choice makes recovery more efficient, since offsetting usually brings the economic benefit sooner.

There is also the mandado de segurança (a fast-track constitutional writ), available to declare the right to offset when the dispute is purely legal and the evidence is documentary. Súmula 213 of the same Superior Court of Justice recognizes this route as appropriate for declaring the right to tax offsetting.

Choosing between the action for recovery and the mandado de segurança depends on the specific case. The mandado de segurança is quick and requires no evidentiary phase, but it cannot be used to collect past amounts in cash. The ordinary action reaches the entire past period, although through a slower procedure.

Offsetting: using the credit to pay off debts

Tax offsetting lets you set a taxpayer’s credits against that same taxpayer’s debts, extinguishing obligations without any cash outlay. Article 170 of the National Tax Code authorizes the law of each government entity to set the conditions and guarantees under which offsetting takes place, which makes it essential to check the applicable rule.

At the federal level, offsetting is done through the electronic declaration mentioned above, in which the taxpayer reports the credit and the debts it intends to pay off. The declaration extinguishes the debt, subject to later approval by the Receita Federal, which has a set period to verify that everything is in order.

For a business, offsetting is often more advantageous than a cash refund. It turns the credit into immediate liquidity, reducing current taxes and improving cash flow without waiting in the precatório queue.

Caution is needed, however. An improper offset, made without a liquid and certain credit, exposes the taxpayer to a fine and to collection of the debt that was supposedly extinguished. That is why the calculation must be solid, with a consistent calculation worksheet and documentation able to withstand an audit.

The five-year deadline and how not to lose your right

The right to recover a tax paid in error is not unlimited. Article 168 of the National Tax Code sets the deadline for requesting a refund at five years, counted, as a general rule, from the extinction of the tax debt, that is, from the date of the undue payment.

This deadline is decisive. Each passing month causes the oldest tax periods to expire, reducing the amount you can recover. A credit that is significant today can shrink considerably if action is postponed, because the five-year window moves forward continuously.

In practice, anyone who periodically reviews their own tax burden preserves their right and avoids losses. This advice applies both to businesses, which should audit their tax calculations regularly, and to individuals, who need to keep receipts and returns to support a possible request.

Gathering organized documentation, calculating the amount with proper adjustment, and choosing the right route, administrative or judicial, are the steps that separate a theoretical credit from an actual recovery. A tax paid without a legal basis belongs to the person who paid it, and getting it back depends only on acting within the deadline.

Frequently Asked Questions

What is the deadline to request a refund of an overpaid tax?

The general deadline is five years, set by Article 168 of the National Tax Code and counted from the date of the undue payment. After that period, the right to a refund expires for the oldest tax periods, which makes periodic review essential if you do not want to lose recoverable amounts.

Is it better to request a cash refund or to offset the credit?

It depends on the taxpayer’s situation. Offsetting is usually more advantageous for those with current tax debts, because it creates immediate liquidity and avoids the precatório queue. A cash refund makes sense for those with no taxes to pay. The Superior Court of Justice recognizes the taxpayer’s freedom to choose between the two.

Do I have to go to court to recover a tax paid in error?

Not always. Many cases are resolved administratively, through a refund request or an offset declaration, with no lawsuit. A court action becomes necessary when the tax authorities refuse to recognize the credit, especially in claims that depend on a declaration of unconstitutionality or on a disputed interpretation of the law.
