Obligations For Yearly IRS Reporting In The Portuguese Tax System

Once you become a tax resident in Portugal, you are required to file an annual tax return, which applies to all sources of income, including any capital gains tax, regardless of their origin.

For the tax year 2025, the deadline for submitting your tax return is set between 1 April and 30 June 2025.

During this period, you have the option to report your income either by yourself or by hiring a qualified accountant to assist you. However, it is important to note that all tax-related procedures must be completed through the Portal das Finanças, the official finance portal in Portugal.

Finance Portal Portugal: Types Of Income To Be Declared

The IRS in Portugal categorises various types of income earned to streamline the reporting process for residents and foreign earners alike. These categories include Category A, which pertains to earned income from dependent employment for those who live in Portugal. Category B covers business and professional income, allowing individuals to report earnings from self-employment or freelance work as part of their annual income in Portugal. Additionally, Category E is designated for capital income, encompassing profits from investments and financial assets, which may include income from property in Portugal. Real estate income falls under Category F, which is associated with a specific tax rate applicable to property earnings. Furthermore, Category G relates to increases in wealth, capturing any appreciation in assets, while Category H is reserved for pensions, ensuring that retirees can report their taxable income accurately. For detailed information on these categories and guidance on reporting your foreign income, it is advisable to visit the Portal das Finanças or consult your accountant for personalised assistance.

Failing To Report?

Failing to report your income may lead to an irregular tax position, which can complicate your residency status under the newly formed AIMA.
If you do not address this issue, attempts to regularise your tax situation could result in back taxes that you owe, compounded interest on those amounts and potential fines.
While it is not common, there is a possibility that you may be flagged by the Portuguese tax authorities, which could further complicate your financial and legal standing in the country, especially if you are an expat in Portugal.
Foreigners living in Portugal must understand the tax system in Portugal to avoid penalties and ensure compliance with the marginal tax rates applicable to their income.

Case Study: Mr. Johns From The UK, His Tax Situation And Residency Renewal

Mr. Johns moved to Portugal before Brexit and was granted automatic residency for five years. He believed that, since all his income was from abroad, he was not required to file taxes in Portugal. However,  he must comply with Portuguese tax laws and report his worldwide income — including any rental income from property in Portugal — as part of his tax obligations.

After the initial five-year residency period, Mr. Johns will need to attend an appointment with AIMA to renew his residency. During this appointment, he will be asked to provide details about his tax records and current tax situation.

If Mr. Johns is unable to demonstrate compliance with Portuguese tax requirements, his application for renewed residency may be at risk.

Conclusion

In conclusion, it is essential for tax residents in Portugal to report their income (including foreign income) every year to the Portuguese IRS.

Accessing the financial portal, the ‘portal das finanças’ is a crucial step in organising expats’ financial affairs.

Keeping up to date with Portuguese regulations can help expats to avoid further problems with renewing their visas/residency rights or the possibility of being flagged by financial authorities.
