Dividend and interest tax in Portugal for expats catches many British arrivals off guard, because UK allowances, ISAs and the way the UK treats non-residents stop helping once you become Portuguese tax resident. Portugal generally taxes residents on worldwide investment income, so dividends from UK shares and funds, interest on UK and offshore savings, and income inside an ISA can all fall within Portuguese tax. Most of this income is taxed at a flat 28%, with an option to aggregate it with your other income at progressive rates, but income paid by entities in jurisdictions on Portugal's official list of clearly more favourable tax regimes, often called the tax haven list, which includes Jersey, Guernsey, the Isle of Man, Gibraltar and the UAE, can be taxed at 35%. This guide explains how Portugal taxes dividends and interest for residents, when aggregation can help, how UK income is treated under the new UK to Portugal treaty, the 35% rule, life insurance contracts, IFICI and what to check before you move. It is general information, not personal tax advice. Portuguese figures are for the 2026 tax year (Portugal's tax year is the calendar year) and UK figures for 2026 to 2027, and the information is correct as at October 2026; rates, the jurisdiction list, treaty interpretation and filing practice can change, so recheck them before you rely on them.
Portuguese tax residents pay personal income tax (IRS) on worldwide income. Dividends, interest and other investment income are capital income (rendimentos de capitais), category E, defined in article 5 of the IRS Code. That covers interest on bank deposits and loans, dividends and other profit distributions, and income distributed by investment funds. For Portuguese-source income, the paying bank or company usually withholds tax at a final rate of 28% under article 71, so in most cases nothing more is due. Income from abroad, such as dividends on UK shares or interest from a UK bank, is not subject to Portuguese withholding, so under article 72 it is taxed at the same special rate of 28% through your annual return. There is no annual tax-free allowance for dividends or interest equivalent to the UK personal savings allowance or dividend allowance, and aggregation, described below, is the main way a lower effective rate can arise. Foreign income is reported on the annual return (Modelo 3), generally on Annex J, which is normally filed between 1 April and 30 June of the following year, so 2026 income is reported in 2027. Our guide to tax in Portugal for expats explains when Portuguese residence starts and how the wider income tax system works.
Instead of the flat 28%, residents can opt to aggregate category E income with their other income (englobamento) under article 72(13), so it is taxed at the progressive rates. For 2026, after the 2026 State Budget (Lei 73-A/2025), the mainland Portugal rates run from 12.5% up to 48% on taxable income above 86,634 euros, and a solidarity surcharge can apply to high incomes. The option generally has to cover all income of the same category for that year, so you cannot pick only the items that suit you, and any Portuguese tax withheld is then treated as a payment on account. Aggregation can increase tax as well as reduce it. It tends to help where total income is modest, for example in the early years of retirement before pensions start, and tends to cost more where income is already in the higher bands. Under article 40-A, where aggregation is chosen, dividends from companies resident in Portugal, and from companies in other EU or EEA states that meet the conditions of the EU Parent-Subsidiary Directive, count at only 50% of their value; for EU or EEA companies you must show the Directive's conditions are met, normally with a certificate from that country's tax authority. Dividends from UK companies do not meet that EU or EEA condition, so they would be included in full. Because the effect depends on your whole income for the year, including any pension, the choice should be modelled before it is made; it is made on each year's return, so it can differ from one year to the next. Restructuring holdings to change how income is taxed can itself create costs, surrender or exit charges, currency risk, other tax charges and extra reporting, and can leave you worse off.
A new UK to Portugal double taxation convention entered into force on 29 December 2025. It has effect for withholding taxes on amounts arising from 1 January 2026, for other Portuguese taxes for taxable periods beginning on or after 1 January 2026, and in the UK for income tax from 6 April 2026, replacing the 1968 convention for later income. Under Articles 10 and 11, dividends and interest paid from the UK to a Portuguese resident may be taxed in Portugal, and, where the treaty conditions are met and you are the beneficial owner, any UK tax is generally limited to 10% of the gross amount, although, subject to the conditions in Article 10, a 15% limit applies to certain dividends paid by property investment vehicles out of income or gains from immovable property. In practice, the UK does not generally withhold tax on dividends, and UK banks and building societies generally pay interest without deduction of tax, so there is often little or no UK tax to credit, and Portuguese tax at 28% or progressive rates may be the principal tax in many cases, depending on the income, payer, treaty position and any UK tax suffered, although some UK tax can still arise, for example on certain property investment vehicle distributions. As a non-resident, your UK income tax on UK savings and dividend income can often be limited under the disregarded income rules, depending on your circumstances, including whether you are entitled to and claim the UK personal allowance, which many non-residents are not; the rules do not make UK savings and dividend income tax-free in Portugal, as our guide to UK income tax for expats abroad explains. ISAs are a UK wrapper: Portugal does not provide an exemption equivalent to the UK ISA exemption, so interest and dividends arising inside an ISA may be taxable to a Portuguese resident and need to be reported. Where foreign tax has actually been paid, article 81 of the IRS Code gives a credit limited to the lower of the foreign tax paid and the Portuguese tax attributable to that income and, where a treaty applies, to the tax the treaty allows the other country to charge; there is no credit where no foreign tax was paid.

Under article 72(18)(a) of the IRS Code, capital income paid by entities without a permanent establishment in Portugal that are domiciled in a jurisdiction on Portugal's official list of countries, territories and regions with clearly more favourable tax regimes, often called the tax haven list, is taxed at 35% rather than 28%. The list is in Portaria 150/2004, as amended, and in 2026 it includes the Channel Islands, including Jersey and Guernsey, the Isle of Man, Gibraltar, the Cayman Islands, Bermuda, the British Virgin Islands and the United Arab Emirates. Hong Kong, Liechtenstein and Uruguay were removed with effect from 1 January 2026 by Portaria 292/2025. This matters for many people arriving from the UK or the Gulf, because offshore savings accounts, funds and other arrangements are often held with providers based in those places. What counts is generally the legal entity that pays the income and where it is domiciled, not the location of a platform, the currency or where an account is marketed, so a provider's exact legal entity needs checking, and not every payment connected with a listed jurisdiction is automatically taxed at 35%. The aggregation option in article 72(13) covers only the income listed in article 72(1), so it does not extend to this 35% income. Our guide to Portugal's tax haven blacklist explains how the list works and how it may change. Knowing where your savings and investments are held, and with which entity, may help identify Portuguese tax and reporting points, but any change should be considered on its own merits and only with suitability and tax advice: whether it is appropriate depends on cost, risk, the other tax consequences and suitability, and for some people the answer will be to make no changes.
Income distributed by investment funds is category E income under article 5(2)(j), so distributions from UK or offshore funds are generally taxed at 28%, subject to the fund's classification, or 35% where the paying entity is domiciled in a listed jurisdiction. Accumulation units do not pay out income, and growth is generally taxed when units are sold or redeemed, but classification can depend on the fund's legal form, the type of arrangement, the identity and domicile of the payer and whether the capital gains or capital income rules apply, so it should be confirmed for your own holdings; our guide to capital gains tax in Portugal covers gains on shares and funds. Life insurance and capitalisation contracts have their own rules. Under article 5(3), the positive difference between what is paid out on surrender, partial surrender or maturity and the premiums paid is capital income, provided premiums paid in the first half of the contract represent at least 35% of the total. One fifth of that income is excluded from tax where the payment is made after five and before eight years of the contract, and three fifths after the first eight years. These rules depend on the contract terms, the date premiums were paid, the identity and domicile of the issuer and how the contract is classified in Portugal, so an existing policy's treatment should be confirmed with a Portuguese tax specialist. A contract issued by an insurer domiciled in a listed jurisdiction may fall under the 35% rate. The value of investments can fall as well as rise, product charges, surrender terms and investment risk matter as much as tax, and no contract should be taken out or kept for tax reasons alone.
People who qualify for the IFICI regime under article 58-A of the Tax Benefits Statute, sometimes called NHR 2.0, may, subject to the IFICI conditions, benefit under article 81(4) of the IRS Code from the exemption method on certain foreign-source income, including category E income, for up to 10 years; this is not an automatic exemption for all foreign investment income. The exempt income must still be taken into account to set the rate on other income, and income from entities in listed jurisdictions is taxed at 35% under article 81(5). IFICI is aimed at specific professional activities, such as research, innovation and certain highly qualified roles, and it is not a general exemption for investment income: eligibility depends on the activity, not on being a retiree or investor, and many retirees and passive investors are unlikely to qualify. People still within the old NHR regime under transitional rules have different rules for some foreign income, which need specific advice. On the UK side, if you had sole UK residence for all or part of at least four of the seven tax years before the year you left and return to the UK after a period of non-residence of five years or less, the temporary non-residence rules can tax certain income on your return. For individuals returning to the UK on or after 6 April 2026, the concept of post-departure trade profits has been removed, so dividends and distributions received while temporarily non-resident from a close company (broadly, a company controlled by five or fewer participators or by its directors, including an overseas company that would be close if UK resident), where you were a material participator, or an associate of one, in the tax year of departure or the three previous tax years, can be brought into UK tax in the year of return whether they were paid from profits made before or after you left, subject to the detailed statutory conditions and a new relief for some double taxation. This is particularly relevant to owners of UK family companies, who should take specific advice before relying on any plan to extract profits while abroad; our guide to returning to the UK explains the rules.
Many people arriving in Portugal from the UK are surprised that their ISA income and their offshore savings interest are not outside tax any more. The 35% rate on income paid by entities in places like Jersey or the Isle of Man is a point to check, because it depends on the domicile of the legal entity paying the income rather than where the account seems to be. No change should be made without suitability and tax advice, and for some people the answer will be to make no changes at all.

The UK personal savings allowance and dividend allowance do not apply in Portugal. Once you are Portuguese resident, dividends and interest are generally taxable from the first euro at 28% or, if you opt for aggregation, at progressive rates.
Portugal does not provide an exemption equivalent to the UK ISA exemption. Interest and dividends arising inside an ISA may be taxable in Portugal and need to be reported on your Portuguese return.
Income paid by entities domiciled in Jersey, Guernsey, the Isle of Man, Gibraltar, the UAE and other listed jurisdictions can be taxed at 35%, and cannot be aggregated under the general option. Check which legal entity pays your income, not just where the account is managed.
Aggregation can lower tax where income is modest, but it generally has to cover all income of the same category for the year and UK dividends count in full. The result depends on your total income, including pensions.
The UK does not generally withhold tax on dividends, and UK bank interest is generally paid gross, so there is often no UK tax to credit. Portugal's charge is then often the main tax on that income.
IFICI is aimed at specific professional activities and many retirees and passive investors are unlikely to qualify, and the old NHR regime is closed to new applicants. Without a special regime, foreign investment income is taxed under the normal rules.
A portfolio set up for a UK resident often relies on allowances and wrappers that Portugal does not recognise. Whether anything should change depends on each person's objectives, attitude to risk, costs, tax position and suitability, and often no changes are needed. Knowing how each holding is likely to be treated may help identify the points to report on the first Portuguese tax return.
Illustrative example only, not a real client. This example is simplified and fictional, applies 2026 Portuguese rules and 2026 to 2027 UK rules purely as stated assumptions, ignores currency movements and costs, and is not a guarantee of any outcome. Helen and Paul plan to become Portuguese tax resident in 2027. Between them they hold UK shares and funds producing about 12,000 euros a year in dividends, ISAs producing about 6,000 euros a year, and a savings account with a provider whose legal entity is domiciled in the Isle of Man, paying about 4,000 euros of interest a year. Their other taxable income in Portugal would be modest until Paul's pensions start. They assumed their ISAs and offshore savings would stay outside tax, as they had in the UK.
In a review with a regulated financial adviser, working alongside a Portuguese tax specialist, the analysis indicated that, on these assumed facts, the ISA income and the UK dividends would be within Portuguese tax, and that the interest from the Isle of Man entity could be taxed at 35%. As a simplified, non-advised illustration only, not a tax calculation or an expected liability, 28% of 18,000 euros is 5,040 euros and 35% of 4,000 euros is 1,400 euros; this excludes foreign tax credits, treaty effects, aggregation, surcharges, currency, timing and their individual circumstances. The review explained that aggregation might reduce the tax on the 18,000 euros in years when their other income was low, that the 35% income could not be aggregated, and that the answer could change once the pensions started. It also looked at where their cash and investments were held and with which legal entity, and set out the costs, risks and other tax consequences of changing anything, compared with making no changes.
The outcome is specific to these assumed figures and is not a tax calculation, forecast or recommendation for anyone else. Helen and Paul understood that where their savings were held, and with which entity, would affect their Portuguese tax as much as the amounts, and that whether any change to how their savings and investments were held would be appropriate was a separate question, needing its own suitability assessment and tax advice. Advice in a case like this may equally conclude that no changes are suitable, and it cannot guarantee a tax treatment or investment outcome. Different facts, rates or timing could produce a different or worse result.

Clarity Global Wealth helps people moving to Portugal, or already living there, understand how Portuguese tax could affect the income from their savings and investments before they act. That includes which of your accounts and holdings would produce taxable income, whether any income is paid by entities in listed jurisdictions and could face the 35% rate, how UK dividends, UK interest and ISAs are treated under the new treaty, whether aggregation may be worth modelling, and how any existing life insurance contract would be treated. We can arrange a free introduction to regulated financial planning, which places you under no obligation to proceed with advice or any product, so you can review your position with a regulated financial adviser before making changes to savings or investments, where advice is appropriate. Any charges for advice would be explained to you before you proceed. The value of investments can fall as well as rise, tax treatment depends on individual circumstances and can change, and advice may conclude that no changes are suitable. Clarity Global Wealth does not provide tax, legal or accounting advice, and adviser comments in this guide are general information, not personal recommendations.

Dividends are capital income and are generally taxed at a flat 28%, either by withholding on Portuguese dividends or through your return for foreign dividends. You can opt to aggregate them with other income at progressive rates from 12.5% to 48% for 2026 in mainland Portugal, in which case Portuguese and qualifying EU or EEA company dividends count at 50%. Recheck rates each year.
Yes. Interest on bank deposits is capital income taxed at 28% for residents, withheld at source by Portuguese banks and declared on your return for foreign accounts. Interest paid by entities domiciled in listed jurisdictions, such as Jersey, Guernsey or the Isle of Man, can be taxed at 35%.
Generally not. Portugal does not provide an exemption equivalent to the UK ISA exemption, so interest and dividends arising inside an ISA may be taxable to a Portuguese resident and need to be reported.
The treaty generally allows the UK to tax them at up to 10% of the gross amount, or 15% for certain property investment vehicle dividends, but the UK does not generally withhold tax on dividends, UK bank interest is generally paid gross, and a non-resident's UK tax on this income is generally limited under the disregarded income rules. In many ordinary cases Portugal is the country that collects most of the tax, but this depends on the facts, limited UK tax can still arise and any Portuguese credit depends on the UK tax actually paid.
Portugal taxes capital income paid by entities domiciled in jurisdictions on its official list of clearly more favourable tax regimes, often called the tax haven list, at 35%. In 2026 the list includes Jersey, Guernsey, the Isle of Man, Gibraltar and the UAE. What matters is generally the legal entity that pays the income, so check the provider's details.
Only for people who qualify. Subject to its conditions, IFICI can apply the exemption method to certain foreign-source investment income for up to 10 years, but it is aimed at specific professional activities and many retirees and passive investors are unlikely to qualify. Income from listed jurisdictions is still taxed at 35%.
