Portugal's 2026 property-tax change matters to a foreign buyer because it can move cash forward. The final tax result may later be corrected, but the amount required before the deed can still be based on your status on the acquisition date.
First, what is IMT?
IMT is Portugal's municipal tax on transfers of real estate. It is normally assessed before completion. The paid tax document is needed for the deed and registration, which makes it a closing requirement rather than a bill that arrives months later.
IMT is separate from stamp duty, registration, professional fees, condominium costs and any mortgage taxes or charges. The tax base and rate depend on the property, value, use and buyer circumstances.
What changed in 2026
Decree-Law 97/2026 changed Article 17 of the IMT Code. For the acquisition of an urban property or autonomous unit intended exclusively for housing, the rate is 7.5% when the acquiring individual is not Portuguese tax resident.
This is not simply a higher top band in the ordinary progressive table. It is a status-based rule aimed at acquisitions by non-residents. That is why two buyers purchasing the same apartment on the same day can need different IMT analyses.
The two stated exceptions
- Becoming Portuguese tax resident: the buyer becomes tax resident in Portugal within two years from the acquisition date.
- Qualifying residential rental: the home begins a qualifying residential tenancy within six months, with monthly rent no higher than €2,300, and the statutory duration requirements are met.
For a person relocating into the home, the first exception is the relevant one. The rental exception has its own start date, rent ceiling and continuity conditions and should not be treated as a flexible backup.
Why people call it a residency refund
The legislation does not mean that a buyer can tick “I plan to move” and automatically pay the resident amount at completion. The practical explanation published after the law says that when an exception is later satisfied, the buyer submits a request to the Portuguese Tax Authority for reimbursement of the difference between the tax paid and the amount under the general rates.
Three distinctions matter:
- Tax residence is a legal status. It is not identical to owning a Portuguese address, holding a D7 or D8 visa, or spending a holiday in the country.
- The window is two years from acquisition. Preserve the deed, tax payment, residence evidence and dates.
- The reimbursement is not self-executing. The buyer must make the appropriate request and support it.
Do not spend the refund before it exists.
Fund the completion on the basis of the amount your Portuguese adviser and closing professional confirm. Treat a future reimbursement as a receivable, not as money available for the deed.
A €799,000 cash-flow illustration
At a 7.5% rate, €799,000 produces €59,925 of IMT. Stamp duty at 0.8% of the same illustrative value would be €6,392. Together, those two lines would require €66,317 before considering registration, professional fees, mortgage-related costs or any later IMT reimbursement.
| Illustrative line | Amount |
|---|---|
| Purchase price | €799,000 |
| IMT at 7.5% | €59,925 |
| Stamp duty at 0.8% | €6,392 |
| IMT + stamp duty before any refund | €66,317 |
This is arithmetic, not a closing statement. The taxable base may require comparison values, the general-rate amount depends on the facts, and financing adds its own lines. Obtain a written calculation linked to the exact buyer and property.
A safer buying sequence after the change
- Decide who is buying. Individual names, shares, marital regime and any entity structure affect documents and potentially tax.
- Establish status on the expected deed date. Do not assume that a residence application equals tax residence.
- Request two calculations. Ask for the completion-day tax and the potential general-rate outcome if the two-year residence exception is met.
- Model the bridge. Make sure the higher amount can be funded without relying on a refund date.
- Write the promissory contract around real conditions. Finance, due diligence, document delivery and completion dates need clear treatment before a material deposit is exposed.
- Complete technical and legal due diligence. Confirm title, licensing, plans, condominium records, debts, rights of first refusal where applicable and the match between the property and official documents.
- Keep a residence and refund file. Save proof of tax residence, acquisition tax, deed and communications in one place.
- Apply rather than assume. Make the reimbursement request through the correct Portuguese Tax Authority process with professional help where needed.
Questions to ask before reserving a home
- Am I Portuguese tax resident on the intended acquisition date?
- If not, does the 7.5% rule apply to this buyer and this property?
- What amount must be paid before the deed?
- What would the general IMT calculation be on current facts?
- Which evidence will prove that I became resident within two years?
- Who will submit the reimbursement request and monitor it?
- Could a later change of use or residence affect the result?
- How much euro liquidity should remain after completion?
What did not change
Good buying discipline is still the same. A buyer should independently verify the title and property records, inspect the physical condition, understand the condominium, read the promissory contract and keep tax advice separate from sales material.
A direct private sale does not remove those protections. It simply removes one sales intermediary. At Seaview Mós, buyers can review the floor plan, high-resolution photographs, property details and live video before deciding whether to begin formal due diligence.
