If you're buying property in Portugal in 2026, IMT is the single biggest cost you'll face at the notary — bigger than stamp duty, bigger than legal fees, sometimes bigger than the deposit itself. And the rules just changed. Here's what actually happens, who pays what, and how to avoid overpaying.
What is IMT?
IMT — Imposto Municipal sobre as Transmissões Onerosas de Imóveis — is a one-off municipal tax charged on the transfer of real estate. It's paid by the buyer, calculated on whichever is higher: the price you actually paid or the property's official tax value (the Valor Patrimonial Tributário, or VPT). You settle it through Portal das Finanças before the deed is signed — the notary won't proceed without proof of payment.
Don't confuse it with IMT-IP (Instituto da Mobilidade e dos Transportes), the separate authority that handles vehicle registration and driving licences. Same three letters, completely different institution — this guide is about the property tax.
The big 2026 change: a flat 7.5% for non-residents
For years, everyone — resident or not — paid the same progressive scale. That changed with Decreto-Lei n.º 97/2026, part of the government's wider housing reform package.
A flat 7.5% IMT property transfer tax now applies to buyers who are not tax residents in Portugal, replacing the old tiered brackets for this category of buyer entirely. Several sources give slightly different rollout dates — some cite May 2026, others point to a flat 7.5% IMT rate on the acquisition of urban residential property by buyers who are not tax-resident in Portugal, taking effect on 1 September 2026. Given the moving target, verify the exact effective date and any transitional provisions with a lawyer or accountant before you sign a promissory contract.
The practical effect is real money. On a mid-range purchase, the new rule has the biggest impact in the €200k-€700k range, adding roughly €10,000-€11,000 regardless of exact price within this band. Above roughly €1.15 million, the gap widens to €10k-€17k, and above €1.15M there's no difference at all — because the top resident bracket already sits near 7.5%.
Who counts as a "non-resident" here
The rule is based on tax residency, not nationality — EU and non-EU buyers are treated the same way. Spend 183+ days a year in Portugal and you're generally a tax resident regardless of passport; spend less and buy a holiday home, and the flat rate applies.
Exemptions and refunds
The reform isn't a blanket penalty — there are two escape routes:
- Become a tax resident within two years of the purchase. You can ask the Tax Authority to cancel the difference between the 7.5% paid and the standard progressive rates if you become a Portuguese tax resident within two years of the acquisition.
- Put the property into moderate-rent long-term housing — sign a residential lease with rent capped at €2,300/month within 6 months and keep it for at least 36 months during the first 5 years.
Both routes mean paying the higher amount upfront and reclaiming the difference later, so budget for the full 7.5% at completion regardless of your plans.
Resident vs non-resident: what you'll actually pay
Residents still use the old progressive scale, which starts at 0% and climbs with property value.
| Portuguese tax resident | Non-resident (2026) | |
|---|---|---|
| Rate structure | Progressive, roughly 0–8% by bracket | Flat 7.5% |
| Primary residence relief | Yes, 0% up to ~€106,346 | Not available |
| €300,000 apartment (approx.) | ~€10,000–€12,000 | €22,500 |
| Stamp duty (Imposto do Selo) | 0.8% | 0.8% |
| Refund route if circumstances change | N/A | Become resident within 2 years, or qualifying long-term rental |
These figures are illustrative ranges, not quotes — property value bands, VPT quirks and municipal variations all move the final number. Run your own numbers through our IMT calculator before you commit to a purchase price.
The other costs stacked on top
IMT is the headline, but it's not the only line on your closing statement:
- Stamp duty (Imposto do Selo): a flat 0.8% of the purchase price or VPT, whichever is higher.
- IMI — the annual municipal property tax, typically around 0.3%–0.45% of the VPT, billed every year you own the property.
- AIMI — an additional wealth-style surcharge that kicks in on higher-value holdings; check current thresholds with Finanças before assuming it applies to you.
- Notary, registration and legal fees — usually a smaller slice but still worth budgeting several hundred to a few thousand euros.
Add it up and a non-resident buyer should realistically plan for around 8–9% of the purchase price in acquisition costs, versus roughly 5–6% for a resident buying the same property.
The buying process, step by step
- Reservation/offer — informal, sometimes backed by a small holding deposit.
- CPCV (promissory contract) — the binding preliminary agreement; a deposit (commonly 10–30%) is paid here.
- IMT and stamp duty settled — via Portal das Finanças, before the deed. No payment, no deed.
- Escritura (deed) — signed at the notary, ownership transfers, and the property is registered.
You'll need a NIF (Portuguese tax number) and a Portuguese bank account before any of this can happen — most non-resident buyers arrange both remotely through a fiscal representative. If you haven't sorted your NIF yet, it's worth getting professional help early rather than discovering the gap mid-transaction; see our tax consultation service if you want someone to walk the numbers and paperwork with you before you sign anything.
One thing worth stating plainly: buying property no longer grants a Golden Visa. The real-estate route was removed some time ago, so don't structure a purchase around residency expectations — check our visas pillar if residency by investment is actually your goal.
Common mistakes
- Assuming the resident rate applies because you plan to move here eventually. Unless you're already tax resident at the time of the deed, you pay the non-resident rate and reclaim later — cash flow matters.
- Ignoring the VPT. If the official tax value is higher than your purchase price, IMT is calculated on the VPT, not what you paid.
- Missing the payment window. IMT must be settled before the deed; leave this to the last minute and you risk delaying completion.
- Forgetting IMI and AIMI exist. Buyers budget for IMT and forget the annual bills that follow.
Frequently asked questions
Nationality doesn't matter — only tax residency does. The rule is based on tax residency, not nationality — EU and non-EU buyers are treated the same. An EU citizen who isn't tax resident in Portugal pays the same flat 7.5% as anyone else.
Yes, within limits. If you become a Portuguese tax resident within two years of the purchase, you can apply to the Tax Authority to reclaim the difference between the 7.5% you paid and the standard progressive rate you'd have paid as a resident.
No — they're often confused because the names are so similar. IMT is a one-off tax paid once, at purchase; IMI is an annual municipal property tax you pay every year you own the home.
Finanças uses the VPT, a value it assigns to the property based on location, size, age and other factors, and compares it with your declared purchase price — IMT is charged on whichever figure is higher.
No. The real-estate investment route for the Golden Visa was removed, so a property purchase on its own doesn't create a residency pathway. If residency is the goal, look at routes like the D7 or D8 instead — our visas guide breaks these down.
Property taxes and residency rules are moving fast in Portugal right now, and the gap between "resident" and "non-resident" pricing has never mattered more. Before you sign a CPCV, it's worth having someone check your residency status, your NIF setup and your numbers.
