Owning a holiday home between Alvor and Sagres and letting it to visitors has become a more formal exercise over the past two years. The rules around registration, VAT and income tax have shifted, and several of the changes land squarely on non-resident owners who may not follow Portuguese legislation day to day. This is a practical read of where things stand in 2026 for a let property in the western Algarve, written from the perspective of a management agency that handles the paperwork for owners across Lagos, Praia da Luz and the surrounding villages.
None of this is tax advice, and the detail of any individual return sits with your own accountant. What follows is the framework most owners need to understand before the first guest arrives.
Registration Has To Come First
Any property let to tourists in Portugal operates under the Alojamento Local regime, and it has to be registered before it takes a booking. Registration runs through the Registo Nacional de Turismo, the national register maintained by Turismo de Portugal, and it generates the AL number that platforms and the tax authority expect to see. A property without a valid number is operating outside the rules, and that exposure falls on the owner rather than the guest.
For a villa in Odiaxere or an apartment near Meia Praia the process is the same. The registration ties to the specific unit, the responsible person and the permitted capacity, and it has to be kept current if any of those details change.
- The AL number must be displayed on listings and is checked against the register
- Registration sits with the property, so a sale does not simply transfer it
- Local councils can limit new AL registrations in certain zones, which is worth checking before you buy to let
The VAT Change Most Owners Missed
The change with the widest reach in recent months concerns VAT. Under Decreto-Lei 35/2025, the small-business exemption that historically let low-turnover operators avoid charging VAT no longer works the same way for taxable persons who are not established in Portugal. In practice a non-resident owner letting a property here is now expected to register for and charge VAT from the first Euro of turnover, with the transitional rules taking effect from 1 July 2025.
Accommodation on the Portuguese mainland carries a reduced IVA rate of 6%, so the figure itself is modest, but the obligation to register and file is the part that catches owners out. A resident operator below the threshold can still fall within the older exemption. A non-resident letting the same villa cannot assume they do.
- Non-resident owners should expect to register for VAT rather than rely on the small-business exemption
- The reduced rate on accommodation is 6% on the mainland
- Filing is periodic, so the administration continues through the year rather than once at the end
How The Rental Income Is Taxed
Rental income from an AL property is taxable in Portugal because the property sits here, regardless of where the owner lives. For a non-resident individual the income is generally taxed at a flat IRS rate of 25%. Under the simplified regime that most smaller operators use, the taxable base is not the full receipts. A coefficient of 0.35 is applied to the gross income, so only around a third of turnover is treated as taxable, with the balance treated as deemed costs.
That combination tends to produce a lower effective burden than the headline 25% suggests, though it depends on the property, the occupancy and whether you run simplified or organised accounts. The figures move, so the position should be reviewed each year rather than assumed to hold.
The Costs That Sit Alongside The Tax
Beyond income tax there are the ownership costs that apply whether or not the property lets well. Municipal property tax, the IMI, runs in the region of 0.3 to 0.45% of the rateable value for urban property and is paid in instalments through the year. On purchase there is transfer tax plus stamp duty at 0.8%, and the all-in acquisition costs for an overseas buyer tend to land somewhere around 7 to 10% once legal and registration fees are counted.
Insurance is worth a separate note. Fire cover is compulsory for apartments within a condominium under the Civil Code, but a standalone villa in Burgau or Salema is not caught by that specific obligation, even though cover remains sensible. Owners sometimes assume the rules are identical for every property, and they are not.
What This Means For A Western Algarve Owner
The western Algarve remains a strong letting market, and demand across Lagos, Praia da Luz and the coast towards Vila do Bispo has held up. The tightening of the rules does not change that, but it does raise the administrative floor. An owner who treated letting as a light-touch sideline a few years ago now has registration, VAT and income filing to keep in order, and the penalties for getting them wrong are real.
This is where day-to-day management earns its place. Keeping the AL registration current, handling the VAT position, pricing the property through the season and filing the income correctly is a continuous task rather than a one-off. Owners who market their property within a managed pool of Algarve rentals tend to find the compliance side is simply absorbed into the operation.
Summary
For 2026 the shape is clear enough. Register the property through the national system before letting, expect to deal with VAT as a non-resident from the first Euro, account for income at the flat 25% rate with the 0.35 coefficient under the simplified regime, and budget for the ongoing ownership costs. None of it is prohibitive, but all of it needs doing properly.
If you own a holiday property between Alvor and Sagres and would rather the registration, pricing and compliance ran quietly in the background, our managed holiday letting service handles exactly that, and we are happy to talk through where your property sits.
