With the IOF tax rate rising to 3.5%, understanding how to protect your margins and optimise FX costs has never been more critical. Here’s what every cross-border seller should know and the strategies that can help you stay ahead.
A Tax Rollercoaster That’s Shaking Up Cross-Border Trade
If you’ve seen your Brazilian order costs surge recently or noticed profits quietly eaten away by a line item called IOF,you’re not alone.
2025 has been a turbulent year for merchants selling into Brazil. In May, the government announced a sudden hike in the Tax on Financial Operations (IOF) from 0.38% to 3.5%, triggering confusion and uncertainty across the eCommerce ecosystem.
Within weeks, Congress repealed the move only for the Supreme Federal Court to reinstate the tax again in July.
The result: a rollercoaster few saw coming, and a clear reminder that policy volatility is now part of doing business in Brazil.
What Is IOF, and Why It Matters
The IOF (Imposto sobre Operações Financeiras) is a tax applied to a wide range of financial transactions-credit, insurance, securities, and foreign exchange.
For cross-border sellers, it’s essentially a tax on currency conversion.
Every time a Brazilian customer pays using a credit card or digital wallet that converts BRL into USD (or another foreign currency), IOF is charged on that transaction.
At 3.5%, the impact can be substantial,especially for high-volume merchants managing large monthly inflows.
Behind the Policy: What’s Driving Brazil’s Decision
This IOF hike isn’t arbitrary.It reflects Brazil’s wider fiscal strategy. Facing rising budget pressures, the government has been tightening spending while seeking new revenue sources.
The Ministry of Finance estimates the new rate could add BRL 20.5 billion in revenue for 2025, and double that in 2026. At the same time, BRL 31.3 billion in non-essential public spending has been frozen.
In short: Brazil is walking a fine line,balancing fiscal control with economic growth. For global businesses, this means one thing: expect continued policy shifts and prepare for flexibility.
The Real Impact on Cross-Border Sellers
For merchants, IOF increases translate directly into higher transaction costs and thinner margins.
A merchant processing USD 500,000 in monthly sales to Brazilian customers could now pay an extra BRL 78,000 annually in IOF.
That’s a material hit especially when competition and logistics costs are already high. So how can businesses respond smartly?
Strategies to Navigate Brazil’s IOF Challenge
1. Manage Costs Proactively
Treat IOF as part of your financial model,not a surprise expense.
Build it transparently into your pricing or margin strategy to preserve profitability.
Practical example:
If your monthly IOF exposure is estimated at BRL 1,000 across 5,000 transactions, you could add a small BRL 0.20 “FX adjustment fee” per order, or apply a dynamic margin (e.g. +1%) to cover the cost.
This keeps pricing stable and margins predictable without shocking the end customer.
2. Optimise Payment Pathways
While IOF applies uniformly across payment types, your choice of transaction route can still make a difference.
Local processing paths and locally popular payment methods tend to minimise hidden FX and gateway fees.
Best practices:
- Route payments locally where possible to avoid unnecessary cross-border processing.
- Adopt mainstream local payment methods such as Pix, Pagaleve, or Buy Now Pay Later to improve conversion and reduce costs.
- Communicate clearly to customers that IOF fees are already included.This boosts confidence and checkout completion.
- Regularly audit settlement data to track real vs. expected costs and detect inefficiencies early.
3. Leverage Brazil’s Local Payment Ecosystem
Brazil’s digital payment scene is evolving fast.
- Pix, launched by the Central Bank in 2020, now handles nearly half of all payment volume in Brazil, used by over 140 million consumers.
Its advantages-real-time speed, near-zero fees, and 24/7 availability make it a game-changer for merchants. - Boleto Bancário, a barcode-based cash payment method, remains vital for consumers without cards, covering about 19% of eCommerce spend.
Together, they highlight one key insight: localisation is not optional.It’s a competitive advantage.
At Antom, we enable merchants to integrate Pix and major local wallets such as Mercado Pago and PicPay, helping businesses accept payments securely and efficiently in Brazil’s preferred formats.
4. Mitigate FX and Settlement Risks
Multi-currency settlements can amplify FX exposure and IOF costs especially between BRL and USD.
Whenever possible, settle directly in BRL.
This reduces IOF exposure, simplifies reconciliation, and enhances cost visibility.
During volatile periods, consider FX hedging or forward contracts to protect profits from sharp currency swings.
Antom’s AI-driven FX models can help merchants forecast exposure more accurately and support locked-in settlement rates, keeping risks contained.
5. Think Mid to Long Term
For established players, the goal is resilience,not reaction.
Adopt a phased strategy to stay agile in a shifting regulatory landscape:
- Short term: Explore tax reliefs and alternate payment routes to ease immediate cost pressures.
- Medium term: Transition towards localised settlement models for greater stability.
- Long term: Build flexible business structures and policy response systems to adapt swiftly to new government or fiscal directions.
Reading Between the Lines: Policy as a Power Play
What began as a technical tax issue has evolved into a broader display of political and fiscal balancing.
For international sellers, this is a timely reminder: in emerging markets like Brazil, growth opportunities are vast but so are regulatory complexities.
As tax and trade policies evolve, businesses that can anticipate, adapt, and act decisively will be the ones that thrive.
