Two buyers walk into a notary's office in Lagos in the same week. Both are buying a €250,000 apartment. One pays around €8,000 in transfer tax. The other pays €18,750.
The difference between them isn't the property. It's where they live.
That gap is new, and it's the most important thing to understand about property tax in Portugal right now. The rules changed in 2026, and most guides online haven't caught up. If you're buying, already own, or are thinking about selling from abroad, here's the plain-English version of what you'll actually pay.
When it comes to tax in Portugal for expats, property is where the surprises live. Income tax you can plan for. A €10,000 swing you only discover at the notary's desk is harder to swallow.
The taxes you'll meet, at a glance
Owning Portuguese property touches you at three moments: when you buy, every year you hold it, and when you sell or let it. Here's the whole landscape on one page:

IMT: the transfer tax, and the 2026 change that catches people out
IMT (Imposto Municipal sobre as Transmissões Onerosas de Imóveis) is the biggest single tax you'll pay when you buy, due before you can sign the final deed (the escritura); without proof of payment, the notary won't proceed. It's calculated on the higher of the price you agreed or the property's official tax value (the VPT). For most purchases, that will be the agreed price.
Here's what changed. Under the Construir Portugal housing package (Decree-Law No. 97/2026, in force since May 2026), non-resident buyers of residential property now pay a flat 7.5% IMT, regardless of what the property itself costs. That replaced the progressive second-home scale, under which a non-resident buying a modest flat paid an effective rate of around 2% to 4%.
For a €250,000 holiday flat, that's roughly €10,600 more than under the old scale. On a €1 million villa it's €75,000, which works out to about €15,000 above the old scale. In relative terms, the increase hits cheaper and mid-priced properties hardest. Above €1,150,853, the old scale already applied a flat 7.5%, so nothing changes.
Now the part the headlines leave out: there are three legitimate ways out of the 7.5%. The first applies at the outset: if you have been a Portuguese tax resident at any point in the past, the standard rates apply. The other two work by refund:
- Become a Portuguese tax resident within two years of buying, and you can reclaim the difference between the flat rate and the normal resident scale.
- Put the property on the long-term rental market at a "moderate" rent (the 2026 ceiling is €2,300/month) within six months, and keep it let for at least 36 months, consecutive or not, in the first five years.
In both cases you pay the full 7.5% at completion, then claim a refund from the Autoridade Tributária within six months of becoming resident or signing the lease. So the flat rate stings most on a pure second home you'll never live in or let long-term. If Portugal is going to become your base, the extra cost may well be avoided, but only if you trigger the relief correctly and on time.
What residents and other buyers pay
If you are a Portuguese tax resident buying your primary residence, the old progressive system still applies and it's kind at the bottom. Purchases up to €106,346 in 2026 (the threshold is updated every year) are exempt from IMT entirely. Marginal rates then climb to 8%, with flat rates of 6% and 7.5% at the top of the market. A resident buying a €300,000 main home pays around €10,540, an effective rate of about 3.5% rather than the headline figure.
A few other rates worth knowing:
- Second homes for residents follow a similar scale but tax starts from the first euro with no entry-level exemption.
- Under-35 first-time buyers (IMT Jovem) pay no IMT or stamp duty up to €330,539 in 2026. Between that amount and €660,982, only the excess is taxed, at 8%. The home must be their first and their permanent residence.
- Rural land is taxed at a flat 5%, and commercial property and building plots at 6.5%, whatever your residency.
- Buy through a company in a blacklisted "tax haven" jurisdiction and the rate jumps to a punitive 10%. That blacklist is longer than most people expect, so check before structuring anything clever.
Stamp duty: small, but don't forget it
On top of IMT, every purchase carries stamp duty (Imposto do Selo) at a flat 0.8% of the price or VPT, whichever is higher. With a Portuguese mortgage, a further sliver applies to the loan: 0.5% to 0.6% depending on the term.
It's small, but it belongs in your budget alongside IMT, legal fees (1–2%), notary and registry costs. All in, a non-resident should plan for total acquisition costs of roughly 9–10% of the price. Make sure to budget for that at the offer stage, not when the bill lands.
IMI: the annual one
Once you own, you pay IMI (Imposto Municipal sobre Imóveis) every year. Think of it as the rough equivalent of UK council tax, except it's charged to the owner, not the occupier, and based on the property's official tax value, known as the VPT (Valor Patrimonial Tributário), rather than what you paid.
That matters, because VPTs are often well below market value (sometimes by a factor of three or four on older properties), so the annual bill is usually modest. Rates are set by each municipality (câmara municipal) within a national band:
- 0.3% to 0.45% for urban properties
- 0.8% for rural properties
Because the rate is set locally, two near-identical villas in neighbouring councils can carry different IMI bills, which is worth checking during your due diligence.
A practical wrinkle: IMI is owed by whoever held the property on 31 December of each year. This means that if you complete on 30 December, you pay the IMI for the whole of that year, billed the following spring. You pay it either in one go or in instalments across May, August and November, depending on the amount.
There's a temporary three-year IMI exemption for a primary residence where the VPT is below €125,000 and household income below €153,300. The criteria are narrow, but useful if they apply to you.
AIMI: the quiet wealth tax on bigger portfolios
AIMI (the Adicional ao IMI) is the tax most owners never have to worry about. But if you're buying at the higher end, pay attention.
It's an additional annual tax based on the combined VPT of all your Portuguese residential property. For individuals it kicks in only above €600,000 of VPT (€1.2 million for a couple filing jointly), with tiered rates from 0.7% to 1.5% on the excess. Since that's VPT, not market value, most single-home owners never reach it.
Companies are treated differently, and deliberately so: a company holding Portuguese residential property pays AIMI at 0.4% from the first euro, with no exemption threshold. The tax is assessed in June and paid in September.
When you sell: capital gains tax (mais-valias)
Here's where outdated advice does the most damage. If you've read a guide that says non-residents pay a flat 28% on the whole gain, bin it. That stopped being true in 2023.
After a run of European Court of Justice and Portuguese Constitutional Court rulings, the rules were equalised. Since January 2023, both residents and non-residents are taxed on only 50% of the gain. That half is added to your income and taxed at progressive rates, up to 48% plus a solidarity surcharge on very high incomes. For most sellers the effective rate on the full gain lands between 6% and 24%.
Say a non-resident sells with a €100,000 gain: only €50,000 enters the calculation. The catch is that Portugal looks at your worldwide income to decide which rate band that €50,000 falls into. It doesn't tax your foreign income, but a UK seller on a large salary pays a higher marginal rate than someone with modest earnings.
Three things to bank:
- The gain isn't simply sale price minus purchase price. You apply an inflation coefficient to your original cost (helpful on long-held property) and deduct documented costs: purchase IMT and stamp duty, legal and agent fees, qualifying renovations. Keep every receipt; it's the best way to shrink a future bill.
- Reinvestment relief can wipe out the tax if you sell your main home and reinvest in another permanent home in Portugal or elsewhere in the EU/EEA, from 24 months before to 36 months after the sale. It applies only to your own permanent home, so not to second homes, and in practice not to non-residents.
- Property acquired before 1989 is generally exempt (the cut-off date is 1 January 1989). At the other end, non-resident companies based in blacklisted jurisdictions pay 35% on the gain.
For British owners, a new UK–Portugal double taxation treaty applies from 1 January 2026, replacing the 1968 convention. Portugal keeps the right to tax gains on Portuguese property, and UK residents credit the Portuguese tax against their UK liability, so a sale means filing on both sides of the Channel. Get cross-border advice before you list.
If you rent it out: rental income tax
Letting your property has its own rules. For individuals, net rental income is generally taxed at a flat 28%, but 25% applies to residential leases signed or renewed since October 2023. Longer contracts are taxed progressively less (15%, 10% or 5% for leases of 5, 10 or 20 years or more), and rents within the "moderate rent" ceiling (€2,300/month in 2026) qualify for a 10% rate on income earned until the end of 2029.
The word that matters is net: you can deduct IMI, condominium fees, insurance, maintenance and repairs, and the energy certificate, although mortgage interest, unhelpfully, isn't deductible. You can also opt for progressive rates instead of the flat rate, which occasionally works out better.
Passing it on: inheritance and gifts
Portugal abolished inheritance tax in 2004 and never brought it back. When property passes to close family (a spouse or partner in a legally recognised de facto union, children, grandchildren, parents or grandparents), there's no inheritance or gift tax at all, just a token 0.8% stamp duty on the transfer. Leave it to anyone outside that circle (a friend, a sibling, a niece or nephew) and they pay 10% instead.
The sharper issue for foreign owners isn't the tax, it's forced heirship. Portuguese law reserves a fixed share of your estate (the legítima) for close relatives, which can override what your will says. The fix is to elect, under the EU Succession Regulation, to have the law of your own nationality govern your estate. It’s a clause in your will, not a tax form, but one of the most overlooked steps for foreigners who own a home here.
The practical traps foreigners actually fall into
The taxes are only half the battle. These trip people up in practice:
Get your NIF first. You can't buy, connect utilities or sign the deed without a Portuguese tax number (número de identificação fiscal, or NIF). It's a quick and cheap process, so sort it before you start house-hunting. Residents outside the EU/EEA will need either a fiscal representative or to opt in to the Tax Authority's electronic notifications.
Fiscal representation. Non-residents from outside the EU/EEA (including UK residents) must either opt in to electronic notifications from the Tax Authority or appoint a fiscal representative (representante fiscal) to receive tax-authority correspondence on their behalf. Skip it and you risk missing IMI notes and deadlines you didn’t even know existed.
Go digital on the Portal das Finanças. Register for e-notifications and set up a direct debit (débito direto) for IMI. Post to an overseas address is unreliable, and missed deadlines mean interest and enforcement, so opting for digital updates may be the cheapest insurance you'll ever buy.
Check your VPT. Your caderneta predial shows the official tax value. If it looks high, request a reassessment to lower future IMI and AIMI; if it's suspiciously low, expect the tax authority to revisit it eventually.
Keep your invoices. Purchase costs and renovation receipts come straight off your capital gain when you eventually sell. A shoebox full of organised invoices can be worth thousands.
Mind your home-country filing. Americans file with the IRS wherever they live and Britons now have obligations under the 2026 treaty. Portuguese compliance doesn't switch off your obligations back home.
Key takeaways
If you remember three things from this Portugal tax guide, make them these:
- Non-residents now pay a flat 7.5% IMT to buy, but can reclaim the difference by becoming resident within two years or letting the property long-term. IMI, AIMI and capital gains rules carry no foreign surcharge.
- Capital gains: 50% of the gain is taxable for everyone since 2023. The old 28%-on-everything figure for non-residents is no longer correct.
- The Portugal tax rules around property shifted meaningfully in 2026, and the admin steps (fiscal representation, direct debit, keeping invoices) matter as much as the headline rates.
Frequently asked questions
Do foreigners pay more property tax than locals in Portugal?
Only on the purchase transfer tax (IMT), and only if they are not Portuguese tax residents: non-residents pay a flat 7.5% from 2026. For annual taxes (IMI, AIMI) and capital gains, foreigners pay exactly the same as Portuguese nationals.
How much are total costs to buy property in Portugal as a foreigner?
Budget roughly 9–10% of the purchase price for a non-resident in 2026, covering IMT, 0.8% stamp duty, legal fees (1–2%), and notary and registry costs.
Can I avoid the 7.5% IMT rate for non-residents?
Potentially. The standard rates apply if you have been a Portuguese tax resident at any time in the past. Otherwise, if you become a Portuguese tax resident within two years of buying, or place the property on the long-term rental market at a moderate rent for at least 36 months, you can reclaim the difference between the flat rate and the standard scale.
What is IMI in Portugal and how much is it?
IMI is the annual municipal property tax, charged on the property's official tax value (VPT), not its market price. Urban properties are taxed at 0.3%–0.45% and rural properties at 0.8%, with the exact rate set by each municipality.
Do non-residents pay capital gains tax when selling property in Portugal?
Yes, but since January 2023 only 50% of the gain is taxable, just as it is for residents. The taxable half is taxed at progressive rates, with the band determined by reference to your worldwide income.
Does Portugal charge inheritance tax on property?
No. Portugal abolished inheritance tax in 2004. Property inherited by a spouse or recognised de facto partner, descendants or ascendants is exempt, with only a 0.8% stamp duty on the transfer. Beneficiaries outside that close family pay 10% stamp duty. Separately, forced-heirship rules may apply unless you elect your home-country law in your will.
Do I need a fiscal representative to own property in Portugal?
Only if you live outside the EU/EEA (including the UK), and even then you can opt in to the Tax Authority's electronic notifications instead. Either way, make sure you receive tax correspondence and do not miss deadlines.
