The Mais Habitação law changed the rules for rental registration, contracts, and taxation. Knowing the changes prevents fines and outdated contracts.
The problem
Legislation has changed, and many landlords continue to operate based on the old rules. The result is exposure to fines and contracts that no longer comply with the law.
Key points for the landlord
- Mandatory contract registration with the Tax Authority (AT) within the legal deadline.
- Rent update rules aligned with the official coefficient.
- Reinforced tax obligations, including electronic receipts.
- Changes to short-term contracts and affordable renting.
The cost of operating with outdated rules
Operating outside the current rules risks fines and weakens any future eviction — adding regulatory costs to the already high cost of a default.
Frequently asked questions
Do the old rules still apply to previous contracts?
There are transitional regimes; each contract must be evaluated based on its signing date and the applicable changes. Always consult an updated official source.
