STF Decides: ICMS Charged on Electricity Bills Was Illegal and Millions of Brazilians Have 10 Years to Claim Refund of Overpaid Amounts
The ICMS charged on electricity bills was deemed illegal by the Supreme Federal Court (STF) in a landmark decision made on August 14, 2025. The measure affects millions of Brazilians and requires energy companies to refund amounts overpaid by consumers over the years.
According to labor and social security law specialist, Professor Valter dos Santos, the decision sets a strong precedent for citizens to claim refunds, with a period of up to 10 years to submit refund requests. The ruling also reinforced the understanding that the charge constituted tax overpayment, meaning tax collected without legal support.
How the Improper Charge Worked
For years, energy distributors — such as Neoenergia, Coelba, and others — included the ICMS amount, passed on by the states, in the bills. The problem is that, according to the STF’s interpretation, this pass-through should not apply to all components of the bill, constituting an irregular charge.

In practice, millions of consumers overpaid on their electricity bills without even realizing it. Now, with the decision, these amounts can be recovered through administrative requests or lawsuits, based on Law 14.385/2022, which regulates the refund process.
Rights Guaranteed to Consumers
The STF established three central points that define the next steps for consumers:
- Mandatory Refund – Utilities are responsible for refunding the amounts charged improperly.
- 10-Year Period – Consumers have up to a decade to request a refund, counted from the payment or the approval of any compensation.
- Good Faith Protection – If someone received excess amounts by mistake, they will not be required to refund, as long as they acted in good faith.
This understanding strengthens the actions of consumer protection agencies and creates legal certainty for claims to be recognized throughout the country.
How to Calculate and Request a Refund
To request a refund, the consumer can demand from the utility detailed spreadsheets with the amounts charged as ICMS. Accounting firms and specialized lawyers already offer tools capable of accurately calculating how much was overpaid over the years.
The action can be taken individually or collectively, through associations or public defenders. The amount to be recovered depends on the consumption history of each household or business, but in many cases, it can reach significant figures.
Economic and Legal Impact
The STF’s decision represents not only a victory for consumers but also a milestone in Brazilian tax law. The refund of the ICMS charged on electricity bills could move billions of reais and pressure utilities and states to reorganize their revenue collection flows.
Experts warn that this is a fertile ground for litigation, and the number of actions is likely to grow rapidly. For the public, this is a concrete opportunity to recover amounts overpaid for an essential service.
