NIF, AT & Bureaucracy: The Expat Landlord Setup Checklist

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.

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.
