Anyone buying a home in the Algarve meets IMT fairly early in the process, usually once the purchase price is agreed and the paperwork moves towards completion. It is the municipal transfer tax that a buyer pays on the acquisition, and it is the single largest of the one off purchase costs on most Algarve homes. This guide sets out how the tax works in 2026, what it is likely to cost at a few price points and where it fits within the wider budget.
The rules are national, so the same schedule applies whether the home is in Lagos, Carvoeiro or Tavira. IMT is calculated on the higher of the purchase price and the property’s rateable value, the valor patrimonial tributário, which for most market priced homes means the price. What follows is a general guide rather than tax advice, and your own lawyer or accountant should confirm the figure for a specific purchase.
How IMT Is Structured
IMT runs on a progressive schedule set out in the Código do IMT, the tax authority’s own code. Rather than a single flat percentage, the rate rises in bands as the value climbs, and a deduction known as the parcela a abater is applied within the progressive brackets so the higher rate does not hit the whole price at once. The same schedule applies regardless of whether the buyer is resident in Portugal or not.
There is a common misconception that overseas buyers pay a flat penalty rate. That is not accurate. A non resident buying a second home follows the standard secondary housing table, with the marginal rate stepping up through the bands and only the top slice taxed at the highest percentage.
The 2026 Rate Bands
For a home that is not the buyer’s own permanent residence, which covers most holiday and second home purchases, the 2026 secondary housing bands work along these lines.
- Up to about €106,346 the rate is 1 per cent
- From there to roughly €198,347 the marginal rate moves through 2 and 5 per cent
- The band up to about €330,539 is taxed at 7 per cent
- The band up to about €633,931 is taxed at 8 per cent
- Values from about €633,931 to €1,150,853 carry a flat 6 per cent
- Anything above about €1,150,853 is taxed at a flat 7.5 per cent on the whole value
The thresholds rose by around 2 per cent for 2026 under the state budget, so the exact Euro figures shift a little each year. The headline point is that the 7.5 per cent rate only reaches homes above roughly €1.15 million, and even then it applies as a flat rate rather than an extra penalty on foreign buyers.
What It Works Out At
A few worked examples give a clearer sense of the numbers. These use the 2026 secondary housing schedule and assume the price is higher than the rateable value.
- On a €500,000 villa the IMT comes to about €27,300, once the bracket deduction is applied
- On a €750,000 home the flat 6 per cent band gives roughly €45,000
- On a €1.5 million villa the flat 7.5 per cent produces about €112,500
- On a €4 million villa the same 7.5 per cent works out at €300,000
On top of IMT sits Imposto do Selo, the stamp duty, at 0.8 per cent of the price, so a €500,000 purchase adds a further €4,000 or so. Buyers looking at luxury villas in the Algarve at the upper end of the market should budget carefully here, since the transfer tax on a seven figure home is a substantial sum in its own right.
Where IMT Fits in the Total Budget
IMT is the largest single line, but it is not the only acquisition cost. Notary and land registry fees, legal fees and stamp duty all add to the total, and taken together the one off costs of buying commonly land somewhere around 8 to 10 per cent of the price.
Buyers arranging finance should note that IMT and the other purchase costs generally have to be met from a buyer’s own funds rather than the loan, since a Portuguese mortgage is set against the property value. Non resident mortgages typically run to around 60 to 70 per cent of the price, and a broker such as Inspired Mortgages can talk through how the tax and the deposit sit alongside the loan.
A Note on Timing and Value
IMT is paid before completion, and the notary will not proceed with the deed until it has been settled, so the funds need to be in place ahead of the signing. The tax is assessed on the declared price, which is why an accurate valuation matters. With Algarve prices rising, and idealista’s regional price data showing an asking level of about €4,165 per square metre in July 2026, the value on which the tax is calculated tends to climb with the market.
Summary
IMT is the main tax a buyer meets when purchasing an Algarve home, and it follows a progressive national schedule that is the same for residents and non residents alike. The flat 7.5 per cent band only applies to homes above roughly €1.15 million, while mid range purchases sit in the 6 per cent band and cheaper homes considerably lower. Building the transfer tax, stamp duty and the other costs into the budget from the outset avoids an unwelcome surprise near completion.
