Sesimbra Tourist Tax: What Alojamento Local Hosts Need to Know
Sesimbra is a municipality in the district of Setúbal, on the Setúbal Peninsula south of Lisbon, and one of the most-visited stretches of coastline in the region. As of 2 July 2026 it charges a municipal tourist tax. If you run an Alojamento Local in Sesimbra, Quinta do Conde or Santana, this applies to you now.
Most guides still have Sesimbra wrong. Some list it at €1 per night, some list exemptions that were dropped or added between the consultation draft and the approved text. This guide works from the final Regulamento da Taxa Turística de Sesimbra, approved by the Assembleia Municipal on 7 May 2026 and in force since 2 July 2026.
How much is the Sesimbra tourist tax
Rate: €2.00 per person per overnight stay Minimum age: 13 years and over Maximum: 7 consecutive nights per person, per stay Applies to: tourist developments and Alojamento Local establishments in the municipality Seasonality: none, the same rate applies all year
The €2.00 figure comes from the economic justification annexed to the regulation. The Câmara takes its direct tourism expenditure for 2024, €461,460.16, and divides it by estimated taxable overnight stays. Sesimbra recorded 242,701 overnight stays in 2023. Since no data exists at municipal or NUTS III level on the share of tourists aged 13 or under, the Câmara applies the national average of 16 per cent aged 15 or under, giving 203,869 estimated taxable nights and a cost per night of €2.26. The tax was set below that at €2.00. Note that the cost basis uses a 15-year threshold while the tax applies from 13, so the true cost per taxable night is somewhat lower.
For scale, the regulation records 756 registered Alojamento Local establishments in the municipality as at 31 December 2024.
Who pays and who is exempt
The taxable person is any individual aged 13 or over who spends a paid night in a tourist development or Alojamento Local establishment in the concelho of Sesimbra. Age is proven by identity document or equivalent showing date of birth.
Four exemptions apply under Article 7:
Guests whose stay is motivated by any medical procedure, extended to one companion, even where the patient does not spend the night at the establishment for health reasons. Proof of appointment or provision of medical services, or equivalent document, is required.
Guests with a disability of 60 per cent or more, on presentation of supporting documentation.
Guests with tax residence in the Municipality of Sesimbra.
Guests whose stay is motivated by serious social situations, through the social emergency line, including among others domestic violence and homelessness, and temporary rehousing in cases of catastrophe or severe weather.
That fourth exemption was added between the public consultation draft and the approved text, so any guide relying on the consultation version will be missing it.
Note what is not on the list. There is no exemption for stays offered free of charge by the establishment, and no pilgrim exemption. The disability exemption does not extend to a companion, unlike the medical exemption.
Sesimbra is not covered by Setúbal's tourist tax
Sesimbra sits in the district of Setúbal, and hosts sometimes assume the Setúbal tourist tax applies to them. It does not.
In Portugal the taxa municipal turística is always created at municipal level, by the individual câmara, through its own regulation approved by its own assembleia municipal. There is no district-level or regional tourist tax on the mainland. The district of Setúbal contains thirteen municipalities and each decides separately whether to have a tax, at what rate, with what cap and with what exemptions.
A property in Sesimbra follows the Sesimbra regulation only. Setúbal, Almada and Palmela are neighbouring concelhos with their own separate rules. What determines your obligation is the concelho on your RNAL registration, not the district or the postal region.
How the 7-night cap works
The tax is due per night up to a maximum of seven consecutive nights per person per stay, regardless of whether the booking was made in person, by phone or online.
If the stay is interrupted within the geographic area of the concelho, the count restarts. If a guest checks out, leaves Sesimbra and returns later, that is a new stay and the seven-night clock starts again.
Worked examples
Two adults, four nights 2 guests × 4 nights × €2.00 = €16.00
Two adults and two children aged 15 and 10, seven nights Three taxable guests, since the 10-year-old is below the age threshold 3 × 7 × €2.00 = €42.00
Two adults, twelve-night stay The cap applies from night eight onwards 2 × 7 × €2.00 = €28.00
Two adults, four nights in July, then a separate three-night booking in September Two separate stays, each counted from zero 2 × 4 × €2.00 = €16.00 plus 2 × 3 × €2.00 = €12.00, total €28.00
One adult with a 60 per cent disability certificate plus one companion, five nights The certificate holder is exempt, the companion is not, because the disability exemption does not extend to companions 1 × 5 × €2.00 = €10.00
Who settles it, and how Sesimbra differs from other municipalities
Read this carefully, because Sesimbra is drafted differently from most municipal regulations.
Under Article 8, settlement is the responsibility of the taxable person, that is the guest, and is made through the electronic platform provided by the Câmara. Payment is due in a single instalment, either at the time of booking or at the start of the stay. Where the guest is a minor aged 13 or over, the rules on supplying the incapacity of minors under Article 124 of the Civil Code apply.
Your obligation as operator is to verify, at the moment of booking or check-in, that the tax has been correctly settled and duly paid.
That is a different model from Lisbon, Porto or the Algarve municipalities, where the host settles and remits on the guest's behalf. It also matters for penalties: failure to verify sits in the heaviest fine bracket, alongside failure to settle.
The practical position right now is that the regulation is in force but the electronic platform it depends on may not yet be published. Check the municipality's online services portal at servicosonline.cm-sesimbra.pt for a Taxa Municipal Turística or Alojamento Local section. If nothing is live, contact the Câmara directly before your next check-in rather than assuming the obligation is suspended.
Registration obligations for AL operators
Within 30 days of being assigned an RNAL number, or of obtaining a valid title to open a tourist development, you must register the establishment on the municipal tourist tax platform.
If you already hold registered establishments and open a new one, you have 15 days from obtaining the RNAL number or opening title to add it.
Cessation of activity must be communicated on the platform within 15 days. Ceasing activity does not release you from obligations that arose while the establishment was operating.
Any change or update to your data must be made within 15 days.
The transitional rule in Article 16 is the one to watch. Everyone already holding an RNAL number or already operating when the platform becomes available has 30 days from that date to complete registration. That deadline runs from platform availability, not from the 2 July entry into force, so it may still be ahead of you.
Where to register and pay
Registration, settlement and payment run through the electronic platform provided by the Câmara Municipal de Sesimbra. The municipality's online services portal is servicosonline.cm-sesimbra.pt.
For anything the portal does not cover:
Câmara Municipal de Sesimbra, Rua da República n.º 3, 2970-741 Sesimbra Balcão Único de Serviços, Sesimbra and Quinta do Conde Balcão Único Móvel, which travels around the concelho
Invoicing the tourist tax
Where the tourist tax is charged through the accommodation, standard practice across Portuguese municipalities is to show it as a separate line on the invoice, distinct from the accommodation price and outside the scope of VAT. Many hosts and accounting packages use the M99 exemption reason code.
Because Sesimbra assigns settlement to the guest rather than the operator, the invoicing treatment may work differently here. Confirm the approach with your accountant.
Penalties
Under Article 12, applying the administrative offence regime in Article 90.º-B of the Local Authority Financial Regime:
Failure to register on the platform, or inaccurate or false information provided when settling the tax: €500 to €1,000 for individuals, €1,000 to €2,000 for companies.
Failure to settle the tax, or failure by the operator to verify that the tax has been correctly settled and paid: €1,000 to €8,000 for individuals, €2,000 to €20,000 for companies.
Failure to comply with obligations on cessation of activity and data updates: €100 to €500 for individuals, €200 to €600 for companies.
Negligence is punishable. Unpaid amounts are subject to enforced collection through tax execution proceedings.
Note that the verification obligation sits in the heaviest bracket. An operator who does not check that a guest has paid faces the same penalty band as a guest who did not pay at all.
Annual review
Article 15 of the approved regulation, which was not in the consultation draft, requires the Câmara to evaluate the results of the regulation annually and send a report to the Assembleia Municipal. That is the mechanism through which the rate or the exemptions would most likely be revisited, so expect the first review during 2027.
What to do now
The tax has been in force since 2 July 2026. Three practical steps.
Check whether the municipal platform is live and, if it is, register your establishments. The 30-day transitional window runs from platform availability.
Make sure your guest registration process captures dates of birth reliably. The 13-year threshold and the documentary proof requirement mean age data has to be accurate.
Decide how you will handle the verification obligation at check-in, and keep a record. Under the Sesimbra model, that is where your exposure sits.
Frequently asked questions
Is the tourist tax being charged in Sesimbra? Yes. The Regulamento da Taxa Turística de Sesimbra came into force on 2 July 2026.
How much is the Sesimbra tourist tax? €2.00 per person per night, for guests aged 13 and over, capped at seven consecutive nights per stay.
Is there a low season and high season rate? No. Unlike several Algarve municipalities, Sesimbra applies a single year-round rate.
Do children pay? Guests under 13 do not. Guests aged 13 and over do, and age must be verifiable from an identity document.
Are Sesimbra residents exempt? Guests with tax residence in the Municipality of Sesimbra are exempt.
Sesimbra is in the Setúbal district, does the Setúbal tourist tax apply? No. The tax is set at municipal level and Sesimbra has its own regulation. What determines your obligation is the concelho on your RNAL registration.
What happens if a guest stays longer than seven nights? Only the first seven consecutive nights are taxable. If the guest interrupts the stay and leaves the concelho, the count restarts on return.
Will Airbnb or Booking.com collect it for me? There is no agreement in place for Sesimbra. Assume you handle it yourself unless the Câmara announces otherwise.
Who is legally responsible for paying, the guest or the host? So one of two things will happen once the platform appears:
(1) The platform is host-facing, like every other municipal TMT platform. You declare nights and pay, and the "guest settles" wording becomes a formality describing who bears the cost. This is what I'd expect.
(2)The platform is genuinely guest-facing, and your job is to send guests a link before arrival and confirm payment at check-in.
Nothing in the regulation stops you collecting the €2 per night from the guest and settling on their behalf. It just means that if a guest doesn't pay, the fine for non-settlement is theirs, while the fine for you not having checked is yours.
