As we head toward 2025, Portugal’s tax responsibilities must remain current. This page will review Portugal’s essential tax dates, including valuable tips on when taxes are due and strategies for avoiding last-minute shocks.

Understanding the Tax System in Portugal
Before delving into particular dates, one must first grasp how the Portuguese tax system operates. Portugal’s tax system divides itself into many groups based on the kind of revenue or transaction. Among the central taxes are:
- IRS (Imposto sobre o Rendimento das Pessoas Singulares): This is the personal income tax for individuals.
- IRC (Imposto sobre o Rendimento das Pessoas Coletivas): This is the corporate income tax for companies.
- IVA (Imposto sobre o Valor Acrescentado): The value-added tax (VAT) on goods and services.
- IMI (Imposto Municipal sobre Imóveis): The property tax on real estate.
- IUC (Imposto Único de Circulação): The road tax for vehicles.
Critical Deadlines for Income Taxes (IRS) in 2025
1. Annual IRS Filing Period
One of the most essential tax deadlines is the IRS filing. The IRS submission window for 2025 will span from April 1 to June 30. Those who make money in Portugal—from work, self-employment, or other sources like rental income—should find this filing window meaningful. During this period, people have to turn in their IRS returns (Modelo 3) online using the official tax system.
- Deadline: April 1, 2025, to June 30, 2025.
If you miss this deadline, you may face penalties, so mark your calendar and set reminders.
2. Payment of IRS Tax Due
Should the amount you owe surpass your prepayments and withholdings, you might be liable for taxes after turning in your IRS return. Usually falling on August 31, the deadline for IRS tax payments varies somewhat depending on personal situation.
- Deadline: August 31, 2025.
Corporate Taxes (IRC) Deadlines in 2025
3. Submission of Annual IRC Return
Business tax responsibilities include a vital component called the IRC. Companies must submit their annual IRC returns for the year before May 31, 2025. This applies to every local or international company operating from Portugal.
- Deadline: July 31, 2025.
4. Payment of IRC Tax Due
Like personal income tax, businesses may need to pay any taxes due once the IRC return is submitted. The payment deadline for IRC taxes in 2025 is typically by July 31.
- Deadline: July 31, 2025.
Property Taxes (IMI) Deadlines in 2025
5. Payment of IMI (Property Tax)
For homeowners and property investors, the IMI is an annual tax on the value of your property. The IMI can be paid in instalments or as a lump sum. The specific deadlines for IMI are generally:
- Single payment: In May 2025, for amounts under €100.
- Two instalments: May and November 2025, for between €100 and €500.
- Three instalments: May, August, and November 2025, for over €500.
It’s worth noting that the IMI amount is determined based on the fiscal value of your property, which tax authorities recalculate periodically.
Vehicle Taxes (IUC) Deadlines in 2025
6. Annual IUC (Vehicle Tax) Payment
For those who own a car, motorcycle, or other vehicle in Portugal, the IUC must be paid annually. The deadline for paying your IUC depends on the month of your vehicle’s registration, with the tax due on the last day of the vehicle’s registration month.
- Deadline: Variable based on the vehicle’s registration month, but it falls on the last day of that month.
Important Caveat on Deadlines
Although these figures offer a broad road map for Portugal’s 2025 tax deadlines, it is still important to be alert to any developments. Legislative developments, crises, or economic situations may all affect the dates the Portuguese government sets. For this reason, it’s always a good idea to speak with a qualified accountant who can provide tailored advice depending on the newest rules and your situation.
Tips for Staying on Top of Tax Deadlines
- Set calendar reminders: Use a digital calendar to keep track of tax deadlines so you never miss an important date.
- Work with a tax professional: If you’re unsure about your obligations, it’s always wise to consult an accountant who can guide you through the process.
- Submit early: Filing taxes early gives you ample time to correct errors and ensures you don’t face penalties.
