By Daniel Rolph, Century 21 Team Rolph Properties — IMT is the number that surprises international buyers most, and 2026 changed it more than most years, so here it is properly explained rather than glossed over.
Accurate as of September 2026. Figures reflect the 2026 State Budget (OE 2026) brackets and the non-resident IMT surcharge introduced by Decreto-Lei n.º 97/2026 (in force since 25 May 2026). Both can change; confirm current figures with your lawyer before budgeting.
Our existing guide to the costs of buying property in Portugal covers the full picture of what you'll pay. IMT specifically deserves its own explanation, because it's usually the single largest cost on top of the purchase price — and because a significant change took effect in May 2026 that most generic guides still haven't caught up with.
What is IMT?
IMT (Imposto Municipal sobre as Transmissões Onerosas de Imóveis) is Portugal's property transfer tax — a one-off tax paid by the buyer, calculated on the higher of the purchase price or the property's official taxable value (VPT), and settled before you sign the deed of purchase (escritura). For residents, it's a progressive tax on urban residential property, with different portions of the price taxed at different rates. For non-residents, since May 2026, it works differently — see below, because this is the rate that actually applies to most of our buyers.
Do non-residents pay a different IMT rate?
Yes, and this is the single most important update for anyone buying from abroad. Since 25 May 2026, under Decreto-Lei n.º 97/2026, non-tax-resident buyers of urban residential property in Portugal pay a flat 7.5% IMT rate — regardless of price, and without access to the progressive brackets, discounts, or primary-residence relief that resident buyers get. This applies based on tax residency, not nationality, so it catches EU and non-EU buyers alike if you're not a Portuguese tax resident at the time of purchase. Since the large majority of our Western Algarve clients are buying as non-residents, this flat rate — not the progressive tables below — is the one that will actually apply to most people reading this.
How much does the non-resident flat rate actually cost, in practice?
Take a €300,000 property. A non-resident buyer pays a flat 7.5% — €22,500. A resident buyer of the same property, under the standard progressive brackets, would pay roughly €11,600. That's an extra €10,900 purely because of non-resident status — a genuinely significant difference, and one that catches buyers off guard when they've budgeted from an older guide or a generic percentage they remembered from a friend's purchase a few years ago.
Is there any way to avoid the non-resident rate?
Yes, in two specific circumstances, both structured as a refund rather than an upfront discount — you pay the 7.5% at completion, then reclaim the difference if you qualify:
You become a Portuguese tax resident within two years of the purchase. If you do, you can apply to have the difference between the flat rate and the standard progressive rate refunded.
You put the property into long-term rental at a moderate rent within six months of buying it, and keep it rented for at least 36 months within the first five years. "Moderate rent" is currently capped at around €2,300 a month. This route exists specifically to encourage non-resident-owned property into the long-term rental market rather than sitting empty or on short-term lets, and it lines up with the government's wider housing-supply goals for this package.
Either route requires a formal application to the tax authority, generally within six months of meeting the condition, and neither is automatic — you pay the 7.5% at completion regardless, and the refund follows separately once you've qualified and applied.
What if I'm buying as a resident, or might become one?
If you're already a Portuguese tax resident, or your purchase genuinely will be your primary home (própria e permanente) from day one, the standard progressive brackets apply instead of the flat non-resident rate:
These are also the tables used to calculate your refund if you qualify under either exemption route above — the tax authority works out what you'd have paid as a resident and refunds the difference from the 7.5% you actually paid at completion.
Is IMT the only tax I pay when buying?
No — alongside IMT, you'll also pay Imposto do Selo (stamp duty) at 0.8% of the purchase price or taxable value, whichever is higher, regardless of residency status. On that same €300,000 example, that's a further €2,400. If you're financing part of the purchase, there's a separate, smaller stamp duty on the mortgage itself — typically 0.6% of the loan amount for mortgages of five years or more, or 0.5% for shorter terms.
Are there any other exemptions or reductions?
Rural (rústico) land is taxed differently, at a flat 5%, and urban non-residential property (commercial, for example) at 6.5% — both unaffected by the non-resident surcharge, which applies specifically to urban residential property. There are separate rules for certain first-time buyer schemes and urban rehabilitation projects, which change periodically — if either might apply to you, it's worth a specific conversation with your lawyer rather than assuming a rate from this general guide.
When exactly does IMT get paid?
Before completion, not after. Your lawyer or notary will confirm the exact amount — including whether the resident or non-resident rate applies to you — based on the final purchase price, VPT, and your tax residency status, and payment is typically arranged in the days immediately before the deed is signed, since proof of payment is required at the signing itself. This is one more reason budgeting for your total purchase costs early in the process matters, which our broader guide to the real cost of buying property in the Algarve walks through alongside legal and notary fees.
FAQ
Do non-residents really pay more IMT than residents in Portugal? Yes, since 25 May 2026, under Decreto-Lei n.º 97/2026. Non-tax-resident buyers pay a flat 7.5% IMT rate regardless of price, while residents pay progressive rates starting much lower — on a €300,000 property, that's roughly €22,500 for a non-resident versus €11,600 for a resident, a difference of nearly €10,900.
Can I avoid the non-resident IMT rate if I plan to rent the property out long-term? Yes — if you place the property into long-term rental at a moderate rent (capped at roughly €2,300/month) within six months of purchase and keep it rented for at least 36 months within the first five years, you can apply to reclaim the difference between the 7.5% flat rate and the standard progressive rate. You still pay the 7.5% upfront at completion; the refund follows once you've met and applied under the condition.
What counts as "moderate rent" for the IMT rental exemption? Currently capped at approximately €2,300 a month, roughly 2.5 times the national minimum wage. Confirm the exact current threshold with your lawyer, since this figure is index-linked and can be updated.
Does becoming a Portuguese tax resident later get my extra IMT back? It can — if you become a Portuguese tax resident within two years of your purchase, you can apply to have the difference between the 7.5% flat rate you paid and the standard progressive rate refunded. This needs a formal application; it isn't automatic.
Does the non-resident IMT rate apply to EU citizens too, or just non-EU buyers? It applies based on tax residency, not nationality or EU status — an EU citizen who isn't a Portuguese tax resident at the time of purchase pays the same flat 7.5% rate as a non-EU buyer in the same position.
Is stamp duty included in the IMT rates above? No — stamp duty (Imposto do Selo) is a separate tax, charged at 0.8% of the purchase price or VPT on top of IMT, regardless of residency status. Budget for both together, along with notary, registration, and legal fees, for your true all-in purchase cost.
