Brazil’s Supreme Federal Court (STF) has declared unconstitutional the additional ICMS (state value-added tax on goods and services) charged on telecommunications services in Sergipe to fund the State Fund for Combating and Eradicating Poverty. Under the Court’s modulation of effects, the surcharge may not be collected from January 1, 2027, and amounts already paid are preserved.

What the Supreme Federal Court decided

The full Court of the STF held unconstitutional the additional ICMS rate applied to telecommunications services in the state of Sergipe, the proceeds of which went to the State Fund for Combating and Eradicating Poverty. The dispute turned on whether telecommunications qualify as an essential service and, if so, whether they can be subjected to a higher tax burden through this surcharge.

The Court held that because telecommunications are essential, an aggravated tax rate is not allowed, even when it is tied to a legitimate social purpose. Since Complementary Law 194/2022, telecommunications have been classified among essential goods and services. That classification bars stacking an additional rate on top of the standard rate that applies to other essential services within the state.

The decision confirms a line of case law the STF has followed since its ruling on Topic 745 of general repercussion (the Court’s binding-precedent mechanism). That ruling held that electricity and telecommunications cannot bear an ICMS rate higher than the state’s general rate, given how essential they are to contemporary life.

Modulation of effects and the 2027 cutoff

Although the Court recognized the surcharge as unconstitutional, it modulated the effects of its decision to protect state revenue during the transition. Under the approach it adopted, the surcharge remains payable through December 31, 2026, and may not be collected from January 1, 2027. The modulation serves legal certainty and takes into account the fiscal impact on the state of Sergipe, which must now rearrange the budget tied to its poverty-relief fund.

The approach also protects taxpayers, because it sets a definite date for the end of the levy. Telecommunications carriers and end users can now predict when the tax will stop applying. That lets them adjust contracts, review commercial plans and rework the related ancillary tax compliance obligations.

Pending lawsuits and administrative requests for refunds of tax paid before the decision are likely to be foreclosed by the modulation. The exception is disputes already in progress on the date of the ruling, which will be handled as the Court itself has directed in similar cases.

The prospective effect of the decision balances taxpayer protection against the fiscal sustainability of the state government. That is a model increasingly seen in tax rulings with a large budgetary impact.

What this means for taxpayers and fiscal federalism

The decision directly affects phone, internet and other telecommunications providers operating in the state of Sergipe. From the date set by the Court, these companies’ tax burden returns to the general rate that applies to essential services. That may open the door to revisiting how taxes are passed on to end consumers.

The ruling also sends a signal to the other states that keep an additional ICMS charge on telecommunications tied to poverty-relief funds. The decision formally concerns only Sergipe’s legislation, but its ratio (the legal reasoning behind it) applies equally to similar rules in other states. Those states should reexamine whether their charges are legitimate and amend their laws in advance to avoid mass litigation.

At the federal level, the issue renews the debate over the limits of the states’ power to tax when they create earmarked surcharges, especially on goods and services that Congress, through complementary legislation, has recognized as essential. The trend is toward progressively restricting surcharges on electricity and telecommunications, with states shifting revenue collection to other tax bases.

Frequently Asked Questions

Exactly when does the surcharge in Sergipe end?

The surcharge remains valid through December 31, 2026, and may not be collected from January 1, 2027, under the modulation set by the STF. Until then, the tax remains payable and taxpayers must keep paying it as usual, with no right to a refund of amounts paid during the transition period.

Who can ask for a refund of amounts paid before the decision?

The modulation of effects significantly narrows the situations in which a refund of unduly paid tax is available. As a rule, only taxpayers who filed a lawsuit or an administrative request before the ruling can seek a refund, in line with the Court’s guidance in similar precedents. Each case requires an individual analysis of the filing date and the procedural status of the claim.

Does the ruling apply to states other than Sergipe?

Formally, the ruling concerns only Sergipe’s legislation, but its legal reasoning also reaches additional ICMS charges that other states have imposed on telecommunications services. Taxpayers in states with similar legislation can seek recognition of their situation based on the ratio decidendi (the Court’s core legal reasoning), even though a specific decision on each challenged state law is still pending.
