A Guide to Mais-Valias in Portugal: Understanding Capital Gains Tax

Portugal, known for its picturesque landscapes, rich culture, and pleasant climate, has become an increasingly popular destination for expatriates and investors. While Portugal offers many advantages, including its Non-Habitual Resident tax regime, it's crucial for anyone considering investments in the country to understand the tax implications. One significant aspect of taxation in Portugal is "mais-valias," which refers to capital gains tax. In this blog, we'll explore what mais-valias is, how it works, and some essential considerations for investors in Portugal.


What are Mais-Valias?


Mais-valias is the Portuguese term for capital gains tax, which is levied on the profits earned from the sale of assets, such as real estate, stocks, and other investments. Understanding how this tax is calculated and applied is vital for anyone who intends to buy, sell, or invest in Portugal.


Types of Assets Subject to Mais-Valias

  1. Real Estate: One of the most common applications of mais-valias is on the sale of property. If you sell a property in Portugal, you may be subject to capital gains tax on the profit made from the sale.

  2. Stocks and Securities: Capital gains from the sale of stocks and securities are also subject to mais-valias in Portugal. This includes gains from the sale of shares, bonds, and other financial instruments.

  3. Business Assets: If you own a business in Portugal and sell its assets, any capital gains from the sale may be subject to mais-valias.


Calculating Mais-Valias


The calculation of mais-valias depends on various factors, including the type of asset, the holding period, and the taxpayer's residency status. Here is a basic outline of how mais-valias is calculated for real estate:

  1. Purchase Price: Start with the purchase price of the asset.

  2. Selling Price: Subtract the selling price of the asset.

  3. Costs and Expenses: Deduct any costs and expenses related to the acquisition and sale of the asset. This can include real estate agent fees, legal fees, and property transfer taxes.

  4. Indexation: If you've held the asset for a significant period, you may benefit from indexation. This means that the purchase price is adjusted for inflation to reduce the taxable gain.

  5. Tax Rate: Apply the applicable capital gains tax rate. The rate can vary based on the type of asset and the taxpayer's residency status.

  6. Exemptions and Deductions: Portugal offers various exemptions and deductions, such as the exemption on the sale of a primary residence if certain conditions are met.


Residency Status and Taxation


Your tax liability for mais-valias in Portugal may be influenced by your residency status:

  1. Resident: If you are a tax resident in Portugal, you are generally subject to capital gains tax on both domestic and foreign assets.

  2. Non-Resident: Non-residents are typically subject to capital gains tax only on gains from Portuguese assets. However, tax treaties between Portugal and your home country may affect your liability.



Understanding mais-valias is crucial for investors and property owners in Portugal. Proper tax planning, including taking advantage of exemptions and deductions, can help minimize your tax liability. It's also essential to stay updated on Portuguese tax laws and seek advice from tax professionals or financial advisors who specialize in international taxation to ensure compliance with local regulations. By doing so, you can navigate the Portuguese tax system more effectively while enjoying the many benefits the country has to offer to residents and investors alike.
