Tax Mistakes Freelancers Make in Brazil (and How to Avoid Them)

Freelancing in Brazil gives you freedom, but it also gives you full responsibility for your taxes. The Receita Federal do Brasil (RFB) (Receita Federal) expects freelancers to manage their own ICMS/IPI/ISS and income tax — and mistakes can be costly.

Here are the most common tax errors Brazilian freelancers make and how to avoid them.

1. Not Registering for ICMS/IPI/ISS on Time

Once your taxable turnover exceeds No threshold — all businesses must issue NF-e for goods, NFS-e for services, you must register for ICMS/IPI/ISS. Delaying registration means you owe ICMS/IPI/ISS from the date you should have registered, plus penalties.

4. Mixing Personal and Business Finances
