Brazil and Singapore: double tax agreement, explained
A practical guide for Singapore-based businesses, investors and advisers dealing with Brazil. What the treaty covers, what it does not, and what Brazilian taxes still apply.
Request a Tax Analysis
Brazil and Singapore have a double taxation agreement in force, but it does not eliminate all Brazilian taxes.
The treaty allocates taxing rights on income such as dividends, interest, royalties and capital gains, and sets fixed source-state rate caps for each category. It may reduce Brazilian withholding below the domestic 15% or 25% rate for qualifying recipients. However, CIDE, ISS and IOF are generally outside the treaty’s scope and continue to apply.
The treaty has two separate articles for service-type payments. Article 12 (royalties) covers technical assistance specifically, by operation of the Protocol, and is capped at 10%. Article 13 is a standalone article for technical service fees more broadly, also capped at 10%. The two should not be conflated: the applicable article depends on the nature of the payment.
The treaty also contains a Most Favoured Nation (MFN) clause in its Protocol, but it is narrower than sometimes assumed: it applies only to interest under article 11. If Brazil later agrees a lower interest rate with another non-Latin American country, that lower rate may become available to Singapore recipients.
Brazil signed the OECD’s Multilateral Instrument (MLI) on 20 October 2025, but it has not yet been ratified by Brazil’s National Congress. Singapore has ratified the MLI. Until Brazil ratifies, anti-abuse analysis under this treaty is governed by article 28, not the MLI.
Brazil has promulgated, by Decree 13,005/2026 (published 10 June 2026), the Protocol amending the Brazil-Singapore treaty, signed 17 April 2023 and in force internationally for Brazil since 12 November 2025. This is a targeted correction, not a renegotiation.
The amendment principally corrects the Portuguese wording of article 11(4), on interest beneficially owned by government bodies and wholly owned government agencies, and amends the Protocol’s Portuguese wording on annuities under article 19.
As clarified, interest arising in one State and beneficially owned by the other State’s Government, a political subdivision, or a wholly owned agency (including a financial institution), is taxable only in that other State, but only where the agency receives it in connection with public functions. This is a targeted exemption for qualifying sovereign and public-sector recipients, not a general exemption for private-sector lending.
What the treaty does not do
The treaty does not eliminate Brazilian indirect taxes such as CIDE, ISS, PIS/COFINS-Import or IOF. These apply regardless of the treaty position and are typically borne by the Brazilian payer, adding roughly 15% to 20% beyond the IRRF component.
It does not automatically grant reduced rates. Benefits depend on beneficial ownership, residence, substance and structure, and can be denied under article 28’s limitation-on-benefits and principal-purpose rules where a structure was established principally to obtain treaty benefits.
What the Brazil-Singapore treaty covers
The treaty sets reduced withholding rates and allocates taxing rights between Singapore and Brazil.

What Singapore businesses need to know
Treaty position by payment type
| Payment type | Treaty position | Domestic taxes still to check |
|---|---|---|
| Dividends | 10% cap for ≥25% corporate shareholders (365-day holding test); 15% otherwise | Treaty access, beneficial ownership, Article 28 |
| Interest | 10% cap for qualifying bank / 5-year+ equipment or project finance; 15% otherwise; exemption for qualifying government/public-sector beneficial owners under art. 11(4) | IOF, thin capitalisation, transfer pricing, JCP treatment |
| Royalties (trademarks) | 15% cap | CIDE (if applicable), IOF |
| Royalties (other) | 10% cap | CIDE (if applicable), IOF |
| Technical assistance | 10% cap under art. 12 (Protocol) | CIDE, possible PIS/COFINS-Import / ISS, IOF |
| Technical service fees | 10% cap under art. 13 (standalone, own exclusions) | ISS, PIS/COFINS-Import, CIDE where applicable, IOF |
| Capital gains | Brazil generally retains source-state taxing rights | Domestic non-resident CGT rules |
Rates above are the treaty’s source-state caps; they do not include CIDE, ISS, PIS/COFINS-Import or IOF, which sit outside the treaty and are typically borne by the Brazilian payer, often adding a further 15% to 20% to the total transaction cost beyond IRRF alone.
