The essentials
Practical guide to opening a vacation rental in Portugal: registering with the Tax Authority under Category B with CAE code 55201 or 55204 and activating VIES, RNAL registration with required documents, inspection and safety requirements (fire extinguisher, information book, identification plate, insurance), regular obligations (municipal tourist tax, UCFE guest reporting), and tax obligations (IRS income tax, VAT, Modelo 30, Social Security, IMI). Each obligation is summarised with links to specialist guides.
Renting your property as a vacation rental in Portugal can be a profitable activity, but understanding all the required steps before starting is essential. This guide covers the full process: registering with the Tax Authority, RNAL registration, inspection requirements, regular obligations, and tax obligations.
Before working through the process, it may be worth calculating whether short-term rental pays off for your specific property — a data-driven analysis helps you make the decision with concrete numbers.
Registering with the Tax Authority (Finanças)
The first step is to notify the Portuguese Tax Authority (Autoridade Tributária — AT) of the start of your activity. You will need a Portuguese NIF (tax identification number) and an updated tax address. There are no costs associated with this process.
You will need to fill in the following information in the activity start declaration:
- Activity start date
- Property address (if different from your tax address)
- Type of income: Category B — Business and Professional Income
- CAE code: 55201 (Furnished accommodation for tourists) or 55204 (Other short-term accommodation)
- Estimated revenue for the rest of the year
- Activate intra-community acquisitions of services (VIES)
If expected annual revenue exceeds €200,000 gross, organized accounting with a certified accountant is mandatory. Below that threshold, you can opt for the simplified regime.
Activating VIES should be communicated to online booking platforms (Airbnb, Booking, Vrbo) so that commission invoices are issued without VAT. For more detail on activity codes: CAE code guide for vacation rental in Portugal.
RNAL Registration (Portal or City Hall)
After opening your activity with the Tax Authority, the next step is to register your property in the National Vacation Rental Registry (RNAL — Registo Nacional de Alojamento Local). The application is submitted online through the Public Services Portal. Without digital authentication (Citizen Card, Digital Mobile Key, or a lawyer’s digital certificate), registration must be completed in person at the city hall.
The application is considered approved if the city hall does not raise an objection within 60 days (90 days in containment areas). Objections may arise from errors in the application, lack of appropriate building permits, or violations of established restrictions.
Before applying, verify whether the parish where the property is located has containment zones or a temporary ban on new registrations. In areas where vacation rentals exceed 25% of available housing, new registrations are suspended. If the property is in a building under a horizontal property regime (condominium), check what the owners’ association can require: short-term rentals in condominium buildings.
Required documents:
- Identification document (for individuals) or commercial registration certificate (for legal entities)
- Term of responsibility signed by the property holder
- Property registration certificate if you are the owner
- Proof of multi-risk insurance with civil liability
- Lease contract or enabling document (if you are not the owner)
- Activity start declaration submitted to the Tax Authority
- Condominium meeting minutes with authorization for installation (for hostels only)
- Building use authorization number (for buildings constructed after 1951)
Once approved, the establishment receives an RNAL registration number, which is mandatory on all advertising, commercial documentation, and booking platforms.

Inspection and Mandatory Requirements
After the license application, the city hall has 60 days (90 days in containment areas) to carry out the first inspection of the property and confirm compliance with legal and safety requirements.
The property must:
- Present adequate conditions for the conservation and operation of facilities and equipment
- Be connected to the public water supply network or have a private system with a properly controlled source
- Be connected to the public sewage network or equipped with adequately sized septic tanks
- Have running hot and cold water
- Have windows or balconies with direct access to the outside for ventilation and aeration
- Be equipped with appropriate furniture, utensils, and equipment
- Have a system to block external light
- Have doors with a security system that ensures guest privacy
- Have sanitary facilities with a system that guarantees privacy
Information Book
You must provide an information book about the establishment’s rules and operation, available in Portuguese, English, and at least two other foreign languages. It must include:
- Rules for urban waste collection and separation
- Instructions for using household appliances
- Noise standards and guidelines to avoid disturbing neighbors
- Telephone contact of the person responsible for the establishment
Safety Requirements
For vacation rentals with capacity equal to or less than 10 guests, the following are mandatory:
- A fire extinguisher and fire blanket accessible to guests
- A first aid kit available to guests
- The national emergency number (112) displayed in a visible location
For the full requirements by property type (studio/T1, T2/T3 and T4+) and where to purchase a certified safety kit, see the guide on the short-term rental safety kit in Portugal.
Other Requirements
- A complaints book (available from Imprensa Nacional Casa da Moeda), with a cover page posted in a visible location, indicating: Competent Entity: ASAE — Rua Rodrigo da Fonseca n.º 73, 1269-274 Lisboa
- Multi-risk civil liability insurance covering property damage and claims from guests and third parties resulting from the provision of accommodation services
Identification Plate
Except for registrations in the Housing modality, all establishments must affix the approved identification plate to the main entrance. For full specifications and where to purchase: complete guide to vacation rental signage in Portugal.
Inspection by Other Authorities
Vacation rental establishments may be visited by ASAE (Food and Economic Security Authority) and the city hall for inspections to verify compliance with Decree-Law No. 128/2014 of 29 August. Turismo de Portugal may also inspect the property at ASAE’s request.
Regular Obligations
Municipal Tourist Tax
All vacation rental establishments are required to charge the Municipal Tourist Tax (TMT) to guests. The TMT is exempt from VAT and its collection is mandatory — all establishments must implement it. Tax amounts and conditions vary by municipality — see our complete guide to tourist tax in Portugal for the rates in each municipality. Some platforms (such as Airbnb in Porto and Lisbon) collect the tax directly within their platform.
Host Wise handles tourist tax collection on behalf of all properties it manages.
Guest Reporting to UCFE (former SEF)
All establishments providing paid accommodation to foreign guests must report their stay to the Unidade de Coordenação de Fronteiras e Estrangeiros (UCFE), within three working days of arrival and departure. This is done through the SIBA Portal.
To register guests with SIBA, create an account on the portal and wait 48 hours to receive your activation key. Required data for each guest:
- Full name
- Date of birth
- Nationality
- Passport number or identification document
- Country of origin
- Arrival and departure dates
Host Wise manages all guest reporting to government authorities on behalf of the owners it represents.

Tax Obligations
Vacation rental in Portugal comes with a specific set of tax obligations. For a complete overview of all applicable taxes — categories, rates, deductible expenses, and deadlines — see the article on taxes on short-term rental in Portugal. In summary:
Issuing Receipts
Under the simplified regime, you must issue an invoice for each reservation within 5 days of receiving payment or within 5 days of check-in. Invoices are issued through the Tax Authority Portal (Portal das Finanças), or you can submit the SAF-T file by the 20th of each month.
Income Tax (IRS)
Vacation rental income is declared under Category B of the personal income tax return (IRS). Under the simplified regime, a coefficient of 0.35 applies — meaning only 35% of income is taxed, with the remaining 65% treated as operating costs. There is also the option to declare under Category F (property income), allowing deduction of actual expenses such as condominium fees, renovations, IMI, and utility bills. For full detail on categories, deductible expenses, and filing deadlines: income tax on short-term rental in Portugal.
VAT (IVA)
Property owners with annual turnover below €15,000 (2025 threshold) are exempt from VAT under Article 53 of the IVA Code. Above that threshold, accommodation services are taxed at the reduced rate of 6%. For all information on exemptions, thresholds, periodic declarations, and VAT recovery on expenses: VAT on short-term rental in Portugal.
Modelo 30
If you advertise on non-resident platforms (Airbnb, Booking.com, Vrbo), you are required to declare the commissions paid through the Modelo 30 — even when the withholding tax rate is zero. This is one of the most frequently overlooked tax obligations for vacation rental hosts in Portugal. For full detail: Modelo 30 for short-term rental in Portugal.
Social Security
When you start providing vacation rental services, you are automatically enrolled in Social Security. If your only Category B activity is vacation rental, income is exempt from Social Security contributions. The exemption ends as soon as you earn other Category B income. If not exempt, you must submit quarterly and annual declarations; contributions are paid by the 20th of each month.
IMI (Urban Property Tax)
The IMI rate is set by each municipality within government-defined limits. The 2023 State Budget introduced the possibility of a surcharge of up to 100% on IMI for vacation rental properties, at each municipality’s discretion. Properties in urban pressure zones may face an additional surcharge of up to 25%.

Frequently Asked Questions
Under the simplified regime with annual turnover below €200,000, hiring an accountant is not mandatory for day-to-day management.
