Before you can legally rent out a property in Portugal, you need a NIF, AT lease registration within 30 days, and a compliant NRAU contract. Miss a step and you’re exposed.
The problem
The Portuguese system assumes you’re local and Portuguese-speaking. For an expat, each acronym — NIF, AT, NRAU, IMI — is a small wall, and the AT registration window is just 30 days.
Your setup checklist
- NIF — your Portuguese tax number, required for everything.
- Portuguese bank account — for rent, taxes, and utilities.
- NRAU-compliant lease — signed before move-in.
- AT registration — within 30 days of signing.
- Electronic rent receipts — via the Finanças portal.
- Annual obligations — IRS on income, IMI on the property.
If you live outside Portugal, an accountant for landlords in your region can handle the yearly tax obligations and, in some cases, fiscal representation.
The cost of missing the deadline
Miss the 30-day AT registration and you risk penalties and a weaker hand in any future eviction — the difference between a clean recovery and a messy one.
Frequently asked questions
How do I get a NIF as a non-resident?
Through the Portuguese tax authority, usually via a fiscal representative or lawyer if you’re outside the EU.
