A Rule That Changes the Maths — But Not the Opportunity

If you're a non-resident considering buying property in the Algarve, there's a number you need to know: 7.5%. That's the new flat IMT (Imposto Municipal sobre as Transmissões Onerosas de Imóveis) rate applied to all residential property purchases by non-residents in Portugal, introduced under the Construir Portugal housing package approved by Parliament in February 2026.

For many international buyers — particularly those purchasing a holiday home or investment property in Lagos, Luz, Burgau, or Salema — this change roughly doubles the IMT bill compared to the old progressive scale. But here's the key insight: it doesn't have to apply to you.

What Changed — and Why It Matters

Under the previous system, IMT was calculated on a progressive scale based on property value and intended use. A non-resident buying a €400,000 property as a second home would have paid approximately €18,990 in IMT.

Under the new flat 7.5% rule, that same buyer now pays €30,000 — an increase of over €11,000.

Here's how the numbers compare across typical Algarve price points:

• €300,000 property: Old IMT ~€11,790 → New IMT €22,500 (+€10,710)
• €400,000 property: Old IMT ~€18,990 → New IMT €30,000 (+€11,010)
• €500,000 property: Old IMT ~€26,190 → New IMT €37,500 (+€11,310)
• €750,000 property: Old IMT ~€43,440 → New IMT €56,250 (+€12,810)

Add 0.8% stamp duty on top, and non-residents should now budget 8.3–9% of the purchase price in taxes at completion — up from the previous 6–7%.

Three Legal Ways to Avoid the Flat Rate

The legislation is not a blanket penalty — it's a policy tool designed to encourage either residency or long-term rental supply. Three exemptions exist, and smart investors are already structuring their purchases around them.

1. Become a Portuguese Tax Resident Within 2 Years

If you register as a Portuguese tax resident within 24 months of completing your purchase, you can apply to the Autoridade Tributária (Portuguese Tax Authority) for a refund of the difference between the 7.5% you paid and the amount owed under the standard progressive scale. For buyers planning a permanent or semi-permanent move to the West Algarve, this is the most straightforward route — and the savings can exceed €10,000.

2. Commit the Property to Long-Term Rental

If you place the property on the residential rental market within 6 months of purchase, at a monthly rent of no more than €2,300, and keep it rented for at least 36 months within the first 5 years, the standard progressive IMT rates apply. You pay 7.5% upfront and claim the refund once the rental conditions are met. This route is particularly relevant for buy-to-let investors in Lagos and the surrounding villages.

3. Urban Rehabilitation Areas (ARUs)

Properties in designated urban rehabilitation zones — including parts of Lagos town centre — may qualify for full IMT exemption on the first sale after rehabilitation. This is a compelling angle for investors looking at renovation projects in the historic core of Lagos or older village properties in Burgau and Salema.

What This Means for West Algarve Investors

The West Algarve remains one of Portugal's most resilient and sought-after property markets. Lagos is currently averaging €4,449/m² (Idealista, February 2026), up 8.8% year-on-year, with demand from American, British, German, and Israeli buyers continuing to grow.

The IMT change adds a layer of complexity — but not a barrier. For investors who plan ahead, the exemption routes are real and accessible. The key is structuring the purchase correctly from day one, with the right legal and tax advice in place before signing the promissory contract (CPCV).

At VerLuz.Homes, we work with buyers who are serious about the West Algarve — whether through direct purchase, group investment, or off-market opportunities. Understanding the full cost picture, including IMT, is part of how we help investors make smarter decisions.
