Moving to Spain: complete tax guide for new residents 2026
At a glance — key tax facts for new residents in Spain
Moving to Spain involves far more tax planning than most people anticipate. The Spanish tax system taxes worldwide income and assets once you become resident, and tax-advantaged vehicles from your home country — savings wrappers such as ISAs (UK) or Roth IRAs (US), pension arrangements, investment portfolios — lose their tax-free or tax-deferred status the moment Spanish residency is established. Add to this the absence of split-year treatment, the Modelo 720 overseas assets declaration, and the wealth tax implications of holding significant assets, and it becomes clear why pre-move tax planning is not optional.
This guide covers the key tax issues for anyone moving to Spain: when residency is triggered, what happens to your foreign financial assets, the critical timing issue around property sales, what you need to declare and when, and how double taxation treaties interact with all of it. Where relevant, we use UK and US examples to illustrate points that apply across most countries.
Several of the issues covered in this guide can be managed effectively with advance planning but are very difficult or impossible to resolve once Spanish residency has been established. The year before the move is the most important window for action. Our Moving to Spain consultation is designed specifically for this pre-move planning stage.
When do you become a Spanish tax resident?
Spanish tax residency is established when any one of three conditions is met: you spend more than 183 days in Spain during a calendar year; your main centre of economic interests is based in Spain; or your spouse and dependent children are resident in Spain (in which case residency is presumed unless you can demonstrate otherwise).
The most important feature of Spanish residency rules for new residents is that Spain does not recognise split-year treatment. In the UK, the year of departure or arrival is split into a resident and a non-resident period. Spanish law does not work this way. If you cross the 183-day threshold in a calendar year, you are treated as a Spanish tax resident for the entire year — from 1 January, regardless of when you actually arrived.
This has profound consequences. Income earned in your home country before you moved — salary, rental income, pension withdrawals, dividends, capital gains on foreign assets — may all be included in your Spanish IRPF return for that year. The trigger is crossing 183 days in the calendar year, and the effect is retrospective. This is not a theoretical risk: it is the most common unexpected liability that new Spanish residents face.
If you arrive in Spain in May and spend the rest of the year there, you will likely cross 183 days by November. At that point, Spain treats you as resident from 1 January — and your home country income from January to May is potentially in the Spanish tax base. Bonuses paid in January, pension withdrawals taken in February, a property sale completed in March — all potentially taxable in Spain. Timing your move carefully relative to these events is essential.
Selling your home abroad: the timing issue that catches people out
This is one of the most financially significant planning points for anyone moving to Spain — and one of the most frequently overlooked.
If you sell your home abroad in the same calendar year in which you become a Spanish tax resident, the gain on that sale is potentially subject to Spanish capital gains tax. The Spain-UK double taxation treaty generally allocates taxing rights over gains on immovable property to the country where the property is located — meaning the UK has primary taxing rights on UK property gains.
However, the treaty interaction does not always produce the outcome people expect. In many countries, gains on the sale of a principal private residence are exempt from domestic capital gains tax — for example, Principal Private Residence Relief (PPR) in the UK, or the primary residence exclusion in the US. In Spain, a comparable exemption exists for the sale of the habitual residence (vivienda habitual), but the conditions are significantly more restrictive: the exemption only applies to Spanish residents who reinvest the entire net proceeds in the purchase of a new Spanish habitual residence within two years. Partial reinvestment produces only partial exemption.
The consequence of this asymmetry is important. If the gain is fully exempt in your home country — which is common for primary residences — there is no home country tax against which Spain can give credit under the applicable treaty. If Spain has taxing rights on the same gain (because you are a Spanish resident in the year of sale), and you do not meet the strict reinvestment conditions for the Spanish exemption, the entire gain is taxable in Spain with no offsetting relief. Far from being protected by the treaty, the seller ends up with full Spanish CGT on a gain that was completely tax-free in the home country.
The cleanest solution remains the same: complete the sale of your foreign property in a different calendar year from the year in which you establish Spanish residency. If you sell in one year and move the next, the sale falls entirely outside the Spanish tax year in which residency begins and the issue does not arise.
If your home country exempts the gain on your principal residence — such as PPR relief in the UK or the primary residence exclusion in the US — there is no home country tax for Spain to credit against. If Spain has taxing rights on the same gain and you do not reinvest the full proceeds in a new Spanish habitual residence within two years, the entire gain is taxable in Spain with no offsetting relief. Selling in a different calendar year from the year you become Spanish resident avoids this completely.
Tax-advantaged savings wrappers: what Spain does not recognise
Many countries offer tax-advantaged savings wrappers — accounts where interest, dividends and capital gains accumulate tax-free under domestic law. Examples include ISAs in the UK, Roth IRAs and 401(k) plans in the US, and similar vehicles in other jurisdictions. These wrappers are one of the most common sources of surprise for new Spanish residents.
Spain does not recognise any of these wrappers. From the moment you become a Spanish tax resident, any income or gains generated within a tax-advantaged savings account from another country must be declared in your annual IRPF return and taxed at the Spanish savings income rates — 19% on the first €6,000, 21% between €6,000 and €50,000, 23% between €50,000 and €200,000, 27% between €200,000 and €300,000, and 30% above €300,000.
This applies from the first day of Spanish tax residency. There is no grace period, no transitional arrangement and no Spanish equivalent of these wrappers. The accounts themselves do not need to be closed — you can continue to hold them — but the tax-free status is lost for Spanish purposes from the point residency is established.
The practical implication is that, before moving to Spain, it is worth considering whether to crystallise gains within a tax-advantaged wrapper while still resident in your home country — taking advantage of the domestic exemption before it ceases to apply. Once you are a Spanish resident, disposing of holdings in these accounts generates a taxable event in Spain. The decision depends on the unrealised gains and the expected Spanish tax liability on future income or disposals.
Tax-advantaged savings wrappers held at foreign institutions may be reportable under Modelo 720 — but whether a specific account needs to be declared, and under which category, depends on how Spain classifies its legal nature: as a bank account, as a securities holding, or otherwise. This is not a straightforward determination and varies case by case. If you hold ISAs, Roth IRAs, 401(k)s or equivalent vehicles, the Modelo 720 treatment of each should be assessed specifically for your situation before filing.
Foreign pensions in Spain: income, capital and wealth tax
Pension arrangements from your home country — whether a SIPP or workplace pension (UK), a 401(k) or IRA (US), or an equivalent structure from any other country — all have Spanish tax implications once you are resident in Spain. The treatment varies depending on the type of arrangement.
Pension income and withdrawals
Income received from a foreign pension — whether as a regular drawdown or a lump sum withdrawal — must be declared in the annual IRPF return and is taxed at progressive IRPF rates on the general income base (not the savings base). Most double taxation treaties allocate primary taxing rights over private pension income to Spain as the country of residence. Tax withheld at source in your home country can generally be credited against the Spanish liability, but the Spanish rate determines the final bill.
State or social security pensions are generally taxable in Spain under applicable treaties, though the precise treatment depends on the specific treaty provisions between Spain and your home country. At lower total income levels, the progressive rates may result in a modest or zero Spanish liability on state pension income alone.
Foreign pension capital and the wealth tax problem
This is the issue that surprises most people moving to Spain with significant pension savings. Under Spanish law, recognised pension plans are exempt from wealth tax. However, most foreign pension structures — SIPPs and workplace pensions (UK), 401(k)s and IRAs (US), and equivalents from other non-EU countries — are not recognised as pension plans under Spanish law.
The consequence has two distinct aspects. First, the full capital value of these unrecognised pension arrangements must be declared annually in the wealth tax return (Modelo 714) — generating an ongoing IP liability based on the total value of the fund, even while the capital remains untouched inside the pension. Second, the accumulated value within the fund does not itself trigger IRPF while it stays invested — income tax only arises when funds are actually withdrawn or disposed of. Moving pension capital between funds outside the recognised Spanish or EU system, however, is treated as a full withdrawal and does trigger IRPF on the entire amount in the year of the transfer. For someone with a substantial pension pot, the annual IP liability alone can be material and ongoing.
This is one of the most compelling arguments for considering the Beckham Law for qualifying individuals — under the Beckham regime, the holder is treated as a non-resident for wealth tax purposes and only declares Spanish assets. A SIPP held in the UK falls entirely outside the Spanish wealth tax base for the duration of the Beckham period. See our dedicated guide on the Beckham Law Spain 2026 for full eligibility details.
The full capital value of unrecognised foreign pension arrangements — SIPPs (UK), 401(k)s and IRAs (US), and equivalents from non-EU countries — must be declared annually in the Spanish wealth tax return (Modelo 714). The capital inside the fund does not trigger IRPF while it remains invested — only actual withdrawals or transfers outside the recognised system do. But the annual IP charge on the total fund value can be material. The Beckham Law, where applicable, protects against this IP exposure for up to six years.
Foreign investments and portfolios: income, gains and reporting
Shares, funds, bonds and other investment assets held abroad do not lose their value when you move to Spain — but their tax treatment changes completely.
Income from foreign investments
Dividends, interest and other income generated by foreign investments must be declared in the annual IRPF return and are taxed at savings income rates. This applies regardless of whether the income is reinvested or paid out, and regardless of whether it has been taxed in the source country. Where the UK has withheld tax at source, credit can be claimed against the Spanish liability under the treaty — but the Spanish rate is the ceiling.
There is no equivalent to home country dividend allowances or personal savings allowances in the Spanish system. All investment income above the basic threshold is taxable from the first euro.
Capital gains on foreign assets
Capital gains on the disposal of foreign shares, funds or other assets are taxable in Spain as part of the savings income base. Unrealised gains — increases in value that remain within the portfolio without being sold — do not trigger IRPF: the tax only arises when the asset is actually disposed of. However, the gain is calculated as the difference between the sale price and the original acquisition cost. Spain does not generally step up the cost base to the value at the date of becoming resident, which means gains accumulated before the move are also included in the taxable amount on eventual disposal.
This is another important pre-move planning point: crystallising gains in assets with large unrealised profits before establishing Spanish residency — while still benefiting from UK capital gains tax treatment, including the annual exempt amount — can significantly reduce the Spanish tax exposure on those assets.
Modelo 720: the overseas assets declaration
Modelo 720 is the annual declaration of overseas assets that all Spanish tax residents must file if they hold foreign assets above certain thresholds. It is one of the most important compliance obligations for anyone moving to Spain, and the penalties for non-compliance are among the most severe in the Spanish tax system.
The declaration covers three categories of foreign assets:
- Bank accounts held at foreign financial institutions — declared if the balance exceeds €50,000
- Securities, shares, funds and other investments held through foreign institutions — declared if the total value exceeds €50,000
- Real estate located outside Spain — declared if the acquisition value exceeds €50,000
In the first year of Spanish tax residency, Modelo 720 must be filed for all three categories where the threshold is exceeded, regardless of when the assets were acquired. In subsequent years, a new filing is only required if the value of assets in any category has increased by more than €20,000 compared to the last declaration, or if new assets above the threshold are acquired.
Assets that must typically be declared include: bank and savings accounts held abroad, tax-advantaged savings wrappers (ISAs, Roth IRAs, 401(k)s), foreign pension funds, investment portfolios held outside Spain, foreign property (other than the primary residence if it qualifies for exemption), and any other overseas financial accounts or assets. The deadline for filing Modelo 720 is 31 March of the year following the tax year.
Failure to file Modelo 720, or filing with material errors or omissions, can result in penalties of €5,000 per item of information not declared, with a minimum of €10,000. While recent European Court of Justice rulings have reduced some of the more extreme aspects of the penalty regime, the obligation to file and the consequences of non-filing remain significant. First-year Spanish residents with foreign assets above the thresholds should treat this as a priority filing obligation.
Wealth tax for new Spanish residents with foreign assets
Once you are a Spanish tax resident, you are subject to wealth tax on your worldwide assets — not just Spanish ones. Foreign property, overseas bank accounts, investment portfolios held abroad, and unrecognised pension arrangements are all potentially in the wealth tax base.
The national exemption threshold is €700,000 per person, and Spain’s primary residence is exempt up to €300,000. The regional rules of your autonomous community may provide further relief — in some regions the effective threshold is considerably higher. Recognised pension plans are exempt from wealth tax, but SIPPs, as noted above, are not recognised and must be included at their full capital value.
For people moving with significant assets — a pension pot, an investment portfolio, property retained abroad, and a Spanish home — the combined wealth tax base can be substantial and the annual liability material. Pre-move planning that accounts for the wealth tax position alongside income tax is essential for a complete picture.

Double taxation treaties with Spain
Spain has double taxation treaties with most countries from which expats typically relocate — including the UK, US, Germany, France, the Netherlands and many others. These treaties are the primary mechanism for preventing the same income or gain from being taxed in full in both countries. Each treaty allocates taxing rights between Spain and the other country depending on the type of income and the residency of the recipient.
The general pattern across most treaties is consistent: employment income is taxable in Spain as the country of residence; private pension income is taxable in Spain; gains on immovable property are primarily taxable in the country where the property is located; dividends and interest have shared taxing rights with maximum withholding rates specified in each treaty. Specific provisions vary — the Spain-UK treaty, for example, contains a specific exemption for UK government service pensions (civil servants, NHS, armed forces) (civil servants, NHS, armed forces) which remain taxable only in the UK.
An important practical point: treaty benefits are not automatic. To invoke treaty provisions and benefit from reduced withholding rates or exemptions, you must actively claim the treaty and provide a certificado de residencia fiscal a efectos del convenio — a certificate of fiscal residence for treaty purposes — issued by the AEAT. Without this certificate, foreign institutions may apply standard domestic withholding rates rather than the reduced treaty rates.
The Beckham Law: a tax regime worth considering before you move
For anyone moving to Spain for qualifying employment reasons — regardless of nationality — the Beckham Law offers a flat 24% income tax rate — instead of progressive IRPF rates up to 49% — for up to six years. It also excludes foreign-source income from Spanish taxation altogether, which for those with foreign rental income, dividends, pension income or investment returns can be extremely valuable.
The Beckham Law is particularly relevant for people with significant foreign pension savings, as it also provides non-resident treatment for wealth tax purposes — meaning only Spanish assets are included, and unrecognised foreign pension capital falls entirely outside the Spanish wealth tax base for the duration of the regime.
The application must be filed within six months of registering with Spanish Social Security, and eligibility must be confirmed before applying. See our complete guide: Beckham Law Spain 2026: who qualifies, how to apply and what can go wrong.
Pre-move tax checklist
The following actions should be considered before establishing Spanish tax residency, regardless of which country you are moving from. The window for most of these is the calendar year before the move — once residency is established, several options are no longer available.
- Time the sale of your home abroad carefully. Complete the sale in a different calendar year from the year you establish Spanish residency. Selling in the same year draws the gain into your Spanish IRPF.
- Review unrealised gains in your savings wrappers and investment portfolio. Consider crystallising gains before becoming Spanish resident — while your home country exemptions (ISA wrapper, Roth IRA, etc.) still apply.
- Assess your pension position. Understand the wealth tax exposure on unrecognised foreign pension arrangements once you become a Spanish resident. If eligible, consider whether the Beckham Law protects against this for the first six years.
- Prepare for Modelo 720. Identify all foreign assets above €50,000 in each category. Gather valuations and account details — the first-year filing covers everything regardless of acquisition date.
- Check Beckham Law eligibility. If your move is employment-related, assess whether you qualify and apply within six months of Social Security registration.
- Review any planned pension withdrawals or large income events. If you intend to take a pension lump sum, make large investment disposals or receive a bonus, timing these before the year of residency avoids drawing them into the Spanish tax base.
- Obtain a fiscal residence certificate from your home country tax authority. Required to invoke the applicable double taxation treaty. Request it before leaving — it confirms your tax residency status for treaty purposes and is needed by Spanish institutions.
- Get a NIE number. Required for virtually all tax and financial transactions in Spain. Can be obtained through a Spanish consulate in your home country before the move.
