Dividend and interest tax in Spain for expats is one of the first surprises for British people who move there, because the UK allowances and ISA protection they are used to stop helping once they become Spanish tax resident. Spain generally taxes residents on their worldwide investment income, so dividends from UK shares and funds, interest on UK and offshore savings, and income arising inside an ISA can all fall within Spanish tax. This income goes into the savings base and is taxed at rates from 19% to 30%, with no tax-free allowance equivalent to the UK ones. This guide explains how Spain taxes dividends and interest for residents, which costs can be deducted, how UK income is treated under the UK to Spain double taxation convention, how offshore accounts and life insurance contracts fit in, the Modelo 720 overseas assets return, the Beckham regime and what to check before you move. It is general information, not personal tax advice. Spanish figures are for the 2025 and 2026 tax years (Spain's tax year is the calendar year) and UK figures for 2026 to 2027, and the information is correct as at October 2026; rates, treaty interpretation and filing practice can change, so recheck them before you rely on them.
Spanish tax residents pay personal income tax (IRPF) on worldwide income. Dividends, interest on bank deposits and bonds, and other income from investing capital are generally treated as income from movable capital (rendimientos del capital mobiliario) under article 25 of the IRPF law, and most of it is included in the savings base (base imponible del ahorro), alongside capital gains from selling assets. For 2025, and unchanged for 2026 at the time of writing, the combined state and regional savings scale is 19% on the first 6,000 euros, 21% from 6,000 to 50,000 euros, 23% from 50,000 to 200,000 euros, 27% from 200,000 to 300,000 euros and 30% above 300,000 euros, following the increase in the top rate from 28% to 30% from 1 January 2025 under Ley 7/2024. Unlike the scale for earnings and pensions, the savings scale is the same in most of Spain, although the foral systems of the Basque Country and Navarre have their own rules. There is no annual tax-free allowance for dividends or interest equivalent to the UK dividend allowance or personal savings allowance, and the former 1,500 euro dividend exemption was abolished from 2015. Spanish banks and companies generally withhold 19% on interest and dividends they pay to residents, which is a payment on account against the final bill; foreign payers do not normally operate Spanish withholding, although this depends on the payer and the holding. Foreign income, such as UK dividends or interest from a UK bank, is generally declared on the annual return (Renta), normally filed during the annual campaign that runs from spring to 30 June of the following year (confirm each year's dates with the Spanish tax authority), so 2026 income is reported in 2027. Our guide to tax in Spain for expats explains when Spanish residence starts and how the wider system works.
Spain allows very few deductions against dividends and interest. Under article 26 of the IRPF law, the main deductible costs are the administration and custody charges for securities, where they are directly connected with the securities and properly documented, while fees for discretionary or individualised portfolio management are generally not deductible. Within the savings base, income from capital (such as interest and dividends) and gains and losses from selling assets are first netted separately. Under the statutory ordering rules in article 49, a negative balance in one component can generally be set against a positive balance in the other up to 25% of that positive balance, and any remaining loss can be carried forward for the next four years. This matters if you hold bonds or funds that produce both income and capital losses. Any personal and family minimum not used against the general base can reduce the savings base, which can help people whose income is mainly from investments. Our guide to capital gains tax in Spain explains how gains, losses and the main home reliefs work.
The UK to Spain double taxation convention, signed in 2013, entered into force on 12 June 2014 and has effect for income tax in the UK from 6 April 2015 and for Spanish taxes other than withholding taxes from 1 January 2015; it has since been modified by the Multilateral Instrument. Under Article 10, dividends paid by a UK company to a Spanish resident may be taxed in Spain, and any UK tax is generally limited to 10% of the gross amount, or 15% for certain dividends paid out of property income or gains by an investment vehicle that distributes most of that income annually, such as some property income distributions from UK REITs, subject to the treaty conditions and beneficial ownership. Under Article 11, UK interest beneficially owned by a Spanish resident is taxable only in Spain. In practice, the UK does not generally withhold tax on ordinary dividends, and UK banks and building societies generally pay interest without deduction of tax, so in many common cases there is little or no UK tax to credit and Spanish tax may be the principal tax on this income, although this depends on the holding and your circumstances. As a non-resident, UK tax on UK savings and dividend income may be restricted or absent, for example under the disregarded income rules in section 811 of the Income Tax Act 2007, depending on your circumstances, as our guide to UK income tax for expats abroad explains. ISAs are a UK wrapper and Spain does not provide an equivalent exemption, so interest and dividends arising inside an ISA may be taxable to a Spanish resident and need to be reported. Where foreign tax has actually been paid, article 80 of the IRPF law gives a deduction for international double taxation, generally limited to the lower of the foreign tax paid and the Spanish tax attributable to that income, and, where a treaty applies, to the tax the treaty allows the other country to charge.

Interest on an ordinary savings account held with a provider in Jersey, Guernsey or the Isle of Man is generally taxed in the savings base at the normal savings rates. Spain also keeps its own list of non-cooperative jurisdictions, which can trigger other rules, so the treatment can depend on the paying entity, the jurisdiction and the exact arrangement, and these should be checked for each holding. Distributions from investment funds are generally taxed as savings income when paid, while growth in accumulation units is generally taxed as a gain when the units are sold or redeemed; Spain also allows tax-deferred switches between qualifying collective investment schemes, but the conditions are strict and depend on each fund's legal form and registration, so eligibility should be checked for each holding rather than assumed. Life insurance contracts have their own rules: the gain on surrender, partial surrender or maturity, broadly the amount received less the premiums paid, is generally capital income in the savings base. For contracts where the policyholder bears the investment risk, article 14.2.h of the IRPF law can tax the annual growth each year unless the contract meets conditions that limit the policyholder's choice of investments. These rules depend on the contract terms, the issuer and how the contract is classified in Spain, so an existing policy's treatment should be confirmed with a Spanish tax specialist. The value of investments can fall as well as rise and you may get back less than you put in. Charges, surrender or early exit penalties, currency risk and how the contract is serviced across borders matter as much as tax, any change to an existing contract can itself trigger tax and costs, and no contract should be taken out, kept or surrendered for tax reasons alone or without a suitability assessment.
Spanish residents who hold assets abroad generally have to file an information return, Modelo 720, where the total in a category exceeds 50,000 euros. The three categories are accounts held with financial institutions abroad, securities, funds and insurance or annuity contracts held abroad, and property abroad. The return is generally due between 1 January and 31 March of the following year, and a further return is generally needed when the value of a category has increased by more than 20,000 euros compared with the last return filed for it, or when assets reported are sold or accounts closed. The former specific penalty regime was abolished by Ley 5/2022 after the Court of Justice of the European Union ruled against it in case C-788/19, but failures can still be penalised under the general tax rules, so the obligation should not be ignored. A separate return, Modelo 721, covers virtual currencies held abroad. Investment assets can also count towards Spanish wealth tax and the temporary solidarity tax on large fortunes, depending on their value and your region, as our guide to wealth tax in Spain explains, and they are relevant to Spanish inheritance and gift tax, covered in our guide to inheritance tax in Spain.
The special regime under article 93 of the IRPF law, often called the Beckham Law, since 2023 covers certain employees, remote workers, company directors, entrepreneurs and highly qualified professionals who move to Spain in qualifying circumstances, and some family members; holding investments alone does not qualify. Among other conditions, you must generally not have been Spanish tax resident in the five tax years before the move, and you must opt in within the deadline. People within the regime remain Spanish tax residents, but for the year of arrival and the following five tax years they are taxed under rules based on those for non-residents. Only where the person qualifies and opts in on time, and subject to the regime's detailed rules and the source and characterisation of the income, foreign-source dividends and interest are generally outside Spanish tax, while Spanish-source savings income is taxed at the savings rates set out in article 93. Retirees and people with only investment income will often not meet the qualifying-activity conditions, so eligibility needs an individual assessment. 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, subject to the detailed statutory conditions in section 401C of the Income Tax (Trading and Other Income) Act 2005 as amended, the anti-avoidance provisions and a new relief for some double taxation. This is particularly relevant to owners of UK family companies; our guide to returning to the UK explains the rules.
People arriving in Spain from the UK are often surprised that their ISA income and their offshore savings interest are now within Spanish tax, and that UK tax rarely offsets it because so little is deducted at source. The reporting side matters too: Modelo 720 is easy to overlook in the first year. 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 dividend allowance and personal savings allowance do not apply in Spain. Once you are Spanish resident, dividends and interest are generally taxable in the savings base from the first euro, at rates starting at 19%.
Spain does not provide an exemption equivalent to the UK ISA exemption. Interest and dividends arising inside an ISA may be taxable in Spain and need to be reported on your Spanish return.
The UK does not generally withhold tax on ordinary dividends, and UK bank interest is generally paid gross to non-residents, so there is often no UK tax to credit. In many common cases Spanish tax is then the principal tax on that income.
Accounts, securities, funds and insurance contracts held abroad above 50,000 euros per category generally need to be reported by 31 March of the following year. The old fixed penalties have gone, but failures can still be penalised under the general rules.
Only administration and custody charges for securities are generally deductible. Fees for discretionary portfolio management are generally not, so claiming them can lead to an adjustment.
The regime depends on a qualifying employment, directorship, entrepreneurial or professional activity in Spain, generally requires that you were not Spanish resident in the previous five tax years, and has strict conditions. Retirees and people with only investment income will often not qualify, and their foreign investment income is then taxed under the normal rules.
A portfolio built for a UK resident often relies on allowances and wrappers that Spain 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 what needs to go on the first Spanish return.
Illustrative example only, not a real client. This example is simplified and fictional, applies 2026 Spanish rules and 2026 to 2027 UK rules purely as stated assumptions, ignores currency movements and costs, and is not a guarantee of any outcome. Mark and Susan plan to become Spanish tax resident in 2027. Between them they hold UK shares and funds producing about 14,000 euros a year in dividends, ISAs producing about 5,000 euros a year, and a savings account with a provider in Jersey paying about 3,000 euros of interest a year. Their accounts and investments held outside Spain are worth well over 50,000 euros in each of the first two Modelo 720 categories. They assumed their ISAs would stay outside tax, as they had in the UK, and that UK tax already paid would cover any Spanish bill.
In a review with a regulated financial adviser, working alongside a Spanish tax specialist, the analysis indicated that, on these assumed facts, the ISA income, the UK dividends and the Jersey interest would all fall within the Spanish savings base, and that there would be little or no UK tax to credit. As a simplified, non-advised illustration only, not a tax calculation or an expected liability, the illustrative tax on 22,000 euros using only the stated 2026 savings bands is 19% of 6,000 euros (1,140 euros) plus 21% of 16,000 euros (3,360 euros), or 4,500 euros in total, before any personal minimum, deductible custody charges or other income; this excludes credits, surcharges, currency, timing and their individual circumstances, and it is an arithmetic illustration of the stated rate bands only, not a projection, a calculation of liability or an indication of the tax payable by anyone. The review also flagged that their overseas holdings would need to be reported on Modelo 720 by 31 March 2028 for their first year of residence, and set out the costs, risks and other tax consequences of changing how their savings and investments were held, 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. Mark and Susan understood that their ISAs and offshore savings would not be outside tax in Spain, and that the reporting obligations mattered as much as the tax. 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 Spain, or already living there, understand how Spanish 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, how UK dividends, UK interest and ISAs are treated under the treaty, which costs may be deductible, what needs to be reported on Modelo 720, 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. The introduction is free; any subsequent advice or implementation may be chargeable, and any charges would be disclosed before you agree to 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. Filing Spanish and UK returns is tax-compliance work, so where that is needed we coordinate with qualified tax specialists.

Dividends are generally income from movable capital and are taxed in the savings base at 19% on the first 6,000 euros, 21% up to 50,000 euros, 23% up to 200,000 euros, 27% up to 300,000 euros and 30% above that. Spanish companies generally withhold 19% on account, and foreign dividends are declared on your annual return. Recheck rates each year.
Yes. Interest on bank deposits and bonds is generally taxed in the savings base at the same rates as dividends. Spanish banks generally withhold 19% on account, and interest from UK or offshore accounts is declared on your annual return.
Generally not. Spain does not provide an exemption equivalent to the UK ISA exemption, so interest and dividends arising inside an ISA may be taxable to a Spanish resident and need to be reported.
Under the treaty, UK interest is taxable only in Spain and any UK tax on dividends is generally capped at 10%, or 15% for certain property investment vehicle dividends, subject to the treaty conditions and beneficial ownership. In practice the UK does not generally withhold tax on ordinary dividends and UK bank interest is generally paid gross, so in many common cases Spain collects most of the tax, although this depends on the holding and your circumstances.
Generally yes, if the total in a category, such as accounts held abroad or securities, funds and insurance contracts held abroad, exceeds 50,000 euros. The return is generally due by 31 March of the following year, and a further return is generally needed if a category's value rises by more than 20,000 euros compared with the last return filed for it.
Only for people who qualify and opt in on time. Subject to the regime's detailed rules, foreign-source dividends and interest are generally outside Spanish tax for the year of arrival and the following five tax years. Eligibility depends on a qualifying employment, directorship, entrepreneurial or professional activity in Spain and generally requires that you were not Spanish resident in the previous five tax years, so retirees and people with only investment income will often not qualify.
