The Mais Habitação law reshaped registration, contracts, and tax rules for Portuguese rentals. Staying compliant from abroad means knowing exactly what changed.
The problem
Compliance is hard enough for locals; from abroad, in another language, it’s a minefield. The rules shifted, and many overseas owners are still operating under the old framework without realizing it.
What matters most for a foreign landlord
- Mandatory AT lease registration within the legal window.
- Rent update rules tied to the official annual coefficient.
- Electronic rent receipts via the Finanças portal.
- Changes to short-term and affordable rental regimes.
The cost of non-compliance
Operating outside the current rules risks penalties and weakens any future eviction — stacking regulatory cost on top of the already steep cost of a default.
Frequently asked questions
Where can I confirm the current rules?
Always verify against the Portuguese tax authority and current legislation, ideally with a local lawyer, as the rules continue to evolve.
