If you are moving to Portugal or earning income in the country, understanding Personal Income Tax in Portugal (IRS) is essential. The Portuguese tax system applies different rules depending on your residency status and the type of income you receive.
For expats and foreign residents, the IRS system may include income from employment, investments, rental property, or business activities. Knowing how these categories are taxed can help you plan your finances and stay compliant with Portuguese tax regulations.
This guide explains how Portugal’s personal income tax system works, the main IRS tax brackets, and the types of income that may be taxed.
Tax Residency and Income Tax in Portugal
Your obligation to pay personal income tax in Portugal depends primarily on your tax residency status.
In general, individuals are considered tax residents in Portugal if they:
- Spend more than 183 days in the country during a 12-month period, or
- Maintain a habitual residence in Portugal suggesting it is their main home.
Portuguese tax residents must declare their worldwide income, including income earned abroad. Non-residents are taxed only on income generated in Portugal, such as employment or rental income in the country.
To understand how residency status is determined, see our guide on Tax Residency in Portugal: The 183-Day Rule Explained for Expats.
IRS Tax Rates in Portugal
Portugal uses a progressive personal income tax system, meaning tax rates increase as income rises.
In recent years, IRS tax rates have generally ranged from about 13% to 48% depending on the taxpayer’s income bracket.
Taxable income is calculated after applying deductions and allowances that may reduce the final tax bill. Examples include certain healthcare, education, and family-related expenses.
Married couples and civil partners can also choose to file a joint tax return, which may reduce the effective tax rate depending on household income.

IRS Income Categories in Portugal

- Category G – Capital gains
A full overview of the Portuguese tax framework can be found in our article Taxes in Portugal for Foreigners.
Types of Income Taxed in Portugal
The Portuguese tax system groups income into several categories. Understanding these categories is important because each one may follow different tax rules.
The six main types of income taxed in Portugal include:
- Employment income
- Business or professional income
- Dividend income
- Interest income
- Rental income
- Capital gains
Below is a brief explanation of each category.
1. Employment Income
Employment income includes salaries, bonuses, and other compensation earned through work in Portugal.
This type of income is taxed under the progressive IRS tax brackets, meaning the applicable tax rate depends on your overall annual income.
Employers usually withhold income tax directly from salaries each month and transfer it to the Portuguese tax authority.
2. Business and Self-Employment Income
Freelancers, sole traders, and self-employed professionals pay income tax on their business earnings through the IRS system.
Some professionals may qualify for the simplified regime, where tax is calculated based on turnover rather than actual profit, simplifying accounting and reporting obligations.
If business activities are conducted through a company, profits are generally taxed under corporate income tax (IRC) instead. You can learn more in our guide to Portugal Corporate Income Tax (IRC).
3. Dividend Income
Dividend income refers to profits distributed by companies to their shareholders.
In Portugal, dividends received by individuals are typically taxed at a flat rate of 28%. However, taxpayers may choose to include dividend income within the progressive IRS system if that results in a lower overall tax rate.
In some cases, double taxation agreements may reduce the tax burden when dividends originate from foreign companies.
See our article on Portugal Double Taxation Agreements for more details.
4. Interest Income
Interest income includes earnings from savings accounts, fixed-term deposits, bonds, and other financial investments.
This income is generally taxed at a flat rate of 28%, although taxpayers can choose to include it within the progressive IRS tax brackets if this results in a lower tax liability.
5. Rental Income
Many foreigners invest in Portuguese real estate and earn income by renting out property.
Rental income is usually taxed at a flat rate of 28%, although landlords may deduct certain expenses related to the rental activity before calculating taxable income.
Common deductible expenses include:
- Property management fees
- Maintenance and repairs
- Insurance costs
- Municipal property tax (IMI)
- Interest on property loans
For a broader overview of real estate taxation, see our guide on Property Taxes in Portugal.
6. Capital Gains Tax
Capital gains tax applies when assets such as real estate, shares, or other investments are sold at a profit.
In many cases, individuals are taxed at 28% on capital gains. However, certain situations allow tax relief.
For example, selling a primary residence may qualify for capital gains tax exemption if the proceeds are reinvested into another main residence within Portugal or the European Union.

Filing Your Income Tax Return in Portugal
