Buying property in Portugal involves more than agreeing on a purchase price. One of the most important additional costs buyers need to understand is Municipal Property Transfer Tax, known in Portugal as IMT (Imposto Municipal sobre as Transmissões Onerosas de Imóveis).
For foreign buyers, IMT is a key part of the purchasing process and can significantly affect the overall cost of acquiring property. The amount payable depends on factors such as the property price, location, intended use and residency status.
What is IMT in Portugal?
IMT is a one-off property transfer tax paid when purchasing real estate in Portugal. It applies to most property transactions, including apartments, villas, townhouses and land.
The tax is paid by the buyer and must usually be settled before the final deed (escritura) is signed.
Historically, IMT used a progressive scale based on factors such as:
- The property value
- Whether the property was a main residence or second home
- The type of property being purchased
- The buyer’s residency status
However, changes introduced through Portugal’s 2026 housing reforms have altered how residential purchases by non-residents are taxed.
Who pays IMT?
Historically, non-resident buyers in Portugal were taxed using the same progressive IMT system as residents. However, Portugal has introduced changes aimed at increasing acquisition costs for certain non-resident residential buyers.
Under the updated framework, many non-resident buyers purchasing residential property may now be subject to a flat IMT rate, depending on their tax residency status and the intended use of the property. Some exemptions or adjustments may still apply for buyers who later become Portuguese tax residents or place the property into qualifying long-term rental schemes.
The new 7.5% IMT rate for non-resident buyers
One of the most significant changes to Portugal’s property tax system is the introduction of a flat 7.5% IMT rate for many non-resident buyers purchasing residential property.
Under the updated framework, non-tax residents buying urban residential property may no longer benefit from the traditional progressive IMT scale used by Portuguese residents purchasing a primary residence.
Instead, a flat 7.5% rate is applied based on the property value. This means international buyers purchasing holiday homes, second homes or investment properties may face noticeably higher upfront acquisition costs than in previous years.
For example:
- A €400,000 residential property could now generate an IMT bill of €30,000 before stamp duty and legal fees.
- A €1 million property could result in €75,000 in IMT alone.
Other costs buyers should expect
IMT is only one part of the total cost of buying property in Portugal. Buyers should also budget for:
- Stamp Duty (Imposto do Selo)
- Notary and registration fees
- Legal costs
- Mortgage-related fees (if applicable)
Combined, these additional costs can significantly increase the total amount required at completion.

How foreign buyers usually handle the process
Most international buyers work with Portuguese lawyers or property advisors to manage IMT calculations and payment. This helps ensure the tax is calculated correctly and avoids delays at completion.
Legal representatives can also verify whether any exemptions apply and explain how the property’s intended use affects the rate.
Because Portuguese property transactions involve several administrative stages, professional guidance is common, particularly among non-resident buyers unfamiliar with the system.
Why professional advice matters when buying a home in Portugal
The 2026 changes have made Portugal’s property tax system more complex for international buyers.
Buyers now face questions around:
- Tax residency timing
- Property usage
- Rental commitments
- Eligibility for exemptions
- Future refunds
All of which can affect the final IMT bill significantly.
As a result, many foreign buyers now work closely with Portuguese lawyers, accountants and tax advisors before completing a purchase.
Common mistakes to avoid
One of the biggest mistakes foreign buyers make is focusing solely on the property price without properly accounting for acquisition costs.
IMT can represent a substantial upfront expense, particularly under the updated rules affecting non-resident buyers, and it must usually be paid before completion. When combined with Stamp Duty, legal fees and registration costs, the total amount required at purchase can be significantly higher than expected.
Another common misunderstanding involves how the traditional progressive IMT system works. Some buyers assume that once a property reaches a certain tax bracket, the highest percentage applies to the entire purchase price. In reality, the system historically worked in bands, meaning different portions of the property value were taxed at different rates.
Although many non-resident buyers may now fall under the newer flat-rate framework, confusion between the two systems remains common, especially when researching older online guides.
Buyers also frequently confuse IMT with IMI (Imposto Municipal sobre Imóveis), Portugal’s annual property ownership tax.

Why IMT matters in Portugal’s property market
IMT plays an important role in Portugal’s housing market because it directly affects acquisition costs and buyer affordability. In higher-value markets such as Lisbon, Porto and parts of the Algarve, the tax can represent a substantial upfront expense.
Despite this, Portugal continues to attract international buyers due to its strong lifestyle appeal, residency options and relatively accessible property market compared to some other European destinations.
