Short answer: ISS is Brazil’s municipal tax on services listed in Complementary Law 116/2003. The national framework sets a general 2% minimum and 5% maximum, but the actual rate, service code, payment process and due date depend on the service and the relevant municipality. Imported services can be taxed at the Brazilian recipient’s location. ISS does not apply to qualifying exports of services when the result of the service occurs abroad. [Source: Complementary Law 116/2003, arts. 1–3, 8 and 8-A.]
For a cross-border contract, ISS is only one layer. Review it separately from withholding tax, CIDE, PIS/Cofins-Import, IOF and the IBS/CBS transition. The presence of one tax does not prove that another applies.
What ISS taxes
ISS applies to services in the annex to Complementary Law 116/2003. The name used in a contract does not decide the classification: the law states that the tax can apply regardless of the label assigned to the service. The taxable item must be mapped to the statutory list and the applicable municipal rule. [Source: Complementary Law 116/2003, art. 1 and §4.]
The service price is the general tax base. The provider is generally the taxpayer, while municipal law can assign collection responsibility to another party within the national rules. [Source: Complementary Law 116/2003, arts. 5–7.]
Domestic, imported and exported services
| Scenario | National ISS starting point | Who/location | What must be checked |
|---|---|---|---|
| Domestic service | Taxable if it fits the statutory service list | Generally the provider’s establishment, subject to the exceptions in art. 3 | Service-list item, art. 3 exception, municipal rate and invoice rule |
| Service imported into Brazil | Can fall within ISS when supplied from abroad or begun abroad | Brazilian recipient/intermediary location; the recipient/intermediary is responsible under the national rule | Local registration, invoice/payment process and contractual tax allocation |
| Service exported from Brazil | Exempt when the result occurs abroad | Fact-specific | Evidence showing where the service result occurs; a foreign customer or payment alone is not a complete test |
[Source: Complementary Law 116/2003, arts. 1–3 and 6 §2 I.]
Imported services
The national law covers services from abroad or whose performance began abroad. For the place-of-taxation rule, imported services are connected to the establishment or domicile of the Brazilian recipient or intermediary. The law also makes that recipient or intermediary responsible for the tax. [Source: Complementary Law 116/2003, art. 1 §1, art. 3 I and art. 6 §2 I.]
That national rule does not supply every operational answer. TO_CONFIRM for the relevant municipality: service-list item, local rate, registration, invoice or electronic declaration, payment code and due date.
Exported services
ISS does not apply to qualifying exports of services when the result occurs abroad. The rule does not cover a service developed in Brazil whose result occurs in Brazil. That makes the place of the result the critical evidence question. [Source: Complementary Law 116/2003, art. 2 I and sole paragraph.]
A foreign customer, foreign-law agreement or payment from abroad does not by itself resolve where the result occurred. TO_CONFIRM: complex export cases may require municipal guidance and case-law analysis in addition to the contract and delivery evidence.
How the STJ interprets the “result” of a service
Brazil’s Superior Court of Justice (STJ) applies a case-specific analysis. Its decisions consider the objective of the contract, where the contracted result is produced and where the customer effectively enjoys the service’s utility. Physical performance in Brazil is relevant, but it is not always decisive on its own. [Source: STJ Informativo 719 — REsp 1,805,226/SP.]
- REsp 831,124/RJ (2006): repairs and overhaul of aircraft engines were carried out and completed in Brazil. The STJ held that the service did not qualify as an export. [Source: official STJ judgment.]
- AREsp 587,403/RS (2016): engineering plans prepared in Brazil for works to be executed in France received different treatment because the contractual purpose and intended utility were tied to the foreign project. [Source: STJ Informativo 719.]
- AgInt no AREsp 1,446,639/SP (2019): the STJ expressly discussed result-consummation and result-utility and found that the logistics services at issue were predominantly performed and enjoyed in Brazil. [Source: official STJ judgment.]
- REsp 1,974,556/SP (2025): international-tourism intermediation performed entirely in Brazil did not qualify because the intermediation itself produced its result in Brazil, even though the underlying travel services were abroad. [Source: STJ Informativo 873.]
These precedents do not create a universal safe harbour. Classify the service actually contracted and document where its intended utility is produced and enjoyed.
What is the ISS rate?
Complementary Law 116/2003 sets a 5% national maximum and, as a general statutory rule, a 2% minimum. The applicable rate within that range depends on the listed service and the municipality. [Source: Complementary Law 116/2003, arts. 8 II and 8-A.]
Do not insert a generic percentage into a cross-border contract. First identify the service item and municipality, then verify the current local law. The tax base is generally the service price, subject to statutory rules and any applicable exceptions. [Source: Complementary Law 116/2003, art. 7.]
ISS is not the whole remittance tax stack
For a payment to a nonresident, analyse each tax independently:
- ISS: municipal tax on listed services, including imported-service rules.
- IRRF: federal withholding tax on specified payments to nonresidents.
- CIDE: a federal contribution that may affect specified technology and technical-service arrangements.
- PIS/Cofins-Import: federal contributions with their own import rules.
- IOF: a federal tax that can affect foreign-exchange and other defined transactions.
This list is an issue map, not a statement that all five taxes apply to every payment. Contract wording should separate tax ownership, withholding, gross-up and supporting-document obligations for each relevant item.
When will IBS replace ISS?
The IBS/CBS transition is already underway in 2026; these taxes should not be described merely as future concepts. ISS nevertheless remains in force during the transition. Relative to each municipality’s 2028 rate, the statute reduces ISS by 10% in 2029, 20% in 2030, 30% in 2031 and 40% in 2032. ISS is extinguished from 2033, when the new model becomes fully effective. [Sources: Receita Federal — 2026 transition guidance, Complementary Law 116/2003, art. 8-B and Constitutional Amendment 132/2023, ADCT art. 129.]
The practical point is not that ISS has already ended. Contracts spanning the transition should address the legacy ISS treatment and the future IBS/CBS treatment without double-counting or leaving pricing adjustments undefined. See our tax compliance guide for the broader reporting context.
Contract and evidence checklist
- Describe each service component and map it to the national service list.
- Identify the provider, recipient, intermediary and relevant establishments.
- Test the general place rule and every applicable art. 3 exception.
- For an import, confirm local recipient responsibility and municipal filing steps.
- For an export, retain evidence of delivery, use and the location of the service result.
- Verify the municipality’s current rate, invoice rule, payment code and due date.
- Separate ISS from IRRF, CIDE, PIS/Cofins-Import and IOF in the tax clause.
- Define whether prices are tax-inclusive and whether any gross-up applies.
- Address how pricing and documentation will adapt during the ISS-to-IBS transition.
FAQ
What is ISS in Brazil?
ISS is a municipal tax on services listed in Complementary Law 116/2003. Municipalities administer it within national rules on scope, location, responsibility and rate limits. [Source: Complementary Law 116/2003.]
Who pays ISS on an imported service?
The national law assigns responsibility to the Brazilian recipient or intermediary for a service from abroad, with the place rule tied to that party’s establishment or domicile. Local filing and payment mechanics must still be checked. [Source: Complementary Law 116/2003, art. 3 I and art. 6 §2 I.]
When does ISS not apply to an export of services?
ISS does not apply to a qualifying export when the service result occurs abroad. This treatment does not apply when a service developed in Brazil produces its result in Brazil. STJ case law requires a fact-specific analysis of the contracted objective and where the utility is produced and enjoyed. [Sources: Complementary Law 116/2003, art. 2 I and sole paragraph and STJ Informativo 719.]
What is the ISS rate?
The national statutory range is generally 2% to 5%, but the actual rate depends on the service and municipality. [Source: Complementary Law 116/2003, arts. 8 II and 8-A.]
Has IBS already replaced ISS?
No. The IBS/CBS transition began in 2026, but ISS remains relevant. Its statutory rate reductions relative to 2028 run from 2029 through 2032, and ISS is extinguished from 2033. [Sources: Receita Federal — reform transition and Constitutional Amendment 132/2023, ADCT art. 129.]
