What is IOF Brazil?

Що таке Imposto sobre Operações Financeiras, or IOF, is a Brazilian federal tax for a wide array of operations involving financial, foreign exchange, credit, insurance, and securities. Effective May 2025, alterations to tax regulations and specific government initiatives in Brazil, pertaining to cross-border transactions, credit operations, and supplier financing, are relevant to payment costs and compliance for SaaS and other B2B businesses conducting operations in or with the country.

Decree No. 12,466/2025 (effective May 23, 2025) standardized most foreign exchange operations at a flat 3.5% IOF rate.

The decree also introduced a tiered credit IOF structure based on business type:

Certain types of business transactions will not fall under the new regulations. Examples of business transactions that are still fully tax-exempt are:

•     Personal (individual) loans
•     Student financing and housing loans
•     The return of foreign capital is presently 0%, implying the tax is not currently a factor
•     Certain financed operations limited to specific exempt categories

Any міжнародні транзакції involving payments out of Brazil to foreign suppliers or vendors are taxed at 3.5%.
Direct impacts are:
· Margins: Net profit generated within the country takes into account transaction costs for an entity, along with a 3.5% increment in international fund receipt fees.
· Customer pricing: Costs incurred by Brazilian customers for платежів карткою або банківські перекази influence conversion rate and subscription continuity.
· Supplier expenses: For businesses sourcing B2B goods/services from Brazil that utilize forfait or risco sacado financing, there is now additional IOF on these financing arrangements.
