401(k), IRA and Roth IRA for a resident in Spain
Last updated 22 September 2026 · Reviewed by Jaime Piñeira Pardo, lawyer registered with the ICAM bar, no. 138826 · English version of our Spanish guide.
The short answer
If you are a tax resident in Spain, your 401(k), IRA and Roth IRA are taxed here, even if the money does not leave the United States and was exempt there. Spain does not equate them to a Spanish pension plan. The withdrawal goes into your income tax return, filed from April to 30 June of the following year. Managora calculates and files it for you.

What is new, and the law that applies
- Income tax savings scale: from 1 January 2025, the bracket exceeding €300,000 is taxed at 30%, compared to the previous 28%. This fully affects the withdrawal of a Roth IRA, which goes precisely to that base.
- The 2013 protocol of the treaty with the United States, in force since 27 November 2019, is what allows transferring funds between US retirement plans without Spain taxing the transfer, and what defines what is understood by a pension fund for the purposes of the treaty, including Roth-type plans.
- As of 22 September 2026, there is no reform that changes the treatment of these plans in Spain. What dictates is still the criterion of the Directorate-General for Taxes, with binding responses from 2022, 2024 and 2025 along the same lines: no equating them to a Spanish pension plan.
- The solidarity tax on large fortunes remains in force and is declared on form 718, from 1 to 31 July of the year following the financial year. The order approving the form for each campaign is published in the Boletín Oficial del Estado (Official State Gazette) shortly before the deadline opens, so it is advisable to look at the current version at the AEAT electronic headquarters before filing.
I live in Spain and have a 401(k) in the United States: do I have to declare it?
If you are a tax resident in Spain, you are taxed here on your worldwide income, regardless of where the money is and who pays it to you. You are considered a resident if you spend more than 183 days of the calendar year in Spanish territory, if the main centre of your economic interests is located in Spain, or if your legally non-separated spouse and minor children habitually reside here. Sporadic absences count as days of stay unless you prove your tax residence in another country with an official certificate.
Having the plan is not, in itself, a taxable event. As long as you do not withdraw money, there is no income to declare in your income tax return. What may exist from the first year of residence are reporting and wealth tax obligations, which are explained below, and that is the order in which problems usually arrive: first a reporting obligation that nobody filed, then the income tax.
If the United States also considers you a resident in the same year, a common situation for US citizens and green card holders, there is a residence conflict that is resolved with the tie-breaker rules of the treaty: permanent home available to you, centre of vital interests, habitual abode and, ultimately, nationality. It is not a matter to be resolved from memory or by counting days on a napkin. Before an administration, residence is only proven with the tax residence certificate issued by the competent authority, the AEAT (the Spanish tax agency) in Spain and the IRS in the United States: no private report replaces it. Managora analyses your situation, tells you which tie-breaker rule works in your favour, gathers the evidence and requests the tax residence certificate mentioning the treaty from the AEAT.
When does the income arise: when contributing, while the plan grows or upon withdrawal?
The annual revaluation of the fund is not taxed in Spain as long as you do not receive anything. The criterion of the Directorate-General for Taxes places the income at the time of collection, whether it is a single withdrawal or periodic payments. The fact that your management company sends you a statement with unrealised capital gains does not mean that anything has to be included in that year's income tax return.
The direct transfer from one US plan to another, for example from a 401(k) to an IRA, without you receiving any amount, is not taxed in Spain. The treaty, following the 2013 protocol, defers taxation until the money actually reaches the participant or the beneficiary. The condition is twofold: both must be pension funds for the purposes of the treaty and the transfer must be direct between entities. If the money passes through your current account, or if you move it to a Spanish pension plan, the administrative criterion is that income already exists there.
The contributions you continue to make from Spain do not reduce your taxable base. The Ley del IRPF (Personal Income Tax Law) reserves this reduction for plans regulated in Spain and European occupational pension funds, and a US plan falls outside both categories. In other words: you contribute with money already taxed in Spain and then you are taxed again upon withdrawal, except for the part that the law recognises as a non-taxable contribution.
Is my withdrawal employment income or investment income?
It depends on whether the plan is linked to employment. If it is, as in the case of an employer's 401(k), a 403(b) or an IRA funded from previous employment, the amount collected is employment income: it enters the general base in full and is taxed at your progressive scale, which adds the state part and that of your autonomous region.
If it is not linked to employment, as is the case with a Roth IRA funded by personal savings, the Administration equates it to a life insurance policy. Then it is investment income, it goes to the savings base and only the difference between what is received and the contributions you made is taxed. The difference between one classification and another can be worth several thousand euros in the same operation.
The 40% reduction that capital withdrawals from Spanish pension plans have does not apply: it is a regime designed for plans regulated here, and yours is not. And the classification is decided on the specific contract, not on the commercial name of the product, so it is advisable to have the plan document at hand and not just the statement. Managora reviews it before classifying the income.
Why does a Roth IRA, which is tax-free in the United States, pay taxes here?
Because Spain does not import the US exemption. There is no equivalent exempt figure in the Spanish income tax, and the treaty does not protect it either: as it does not derive from employment, the withdrawal falls under the other income article, which attributes taxation exclusively to the State where the recipient resides. If that State is Spain, you pay in Spain.
The good part is in the calculation base. As it is treated the same as a life insurance policy, the gain is taxed and not the capital: if you withdraw €30,000 from a Roth IRA to which you contributed €20,000, the income to declare is €10,000, not €30,000.
That is why the contribution history is the most valuable document in the folder. It is the proof of what is not taxed, and US management companies do not always issue it with the detail that the Spanish Administration requests. Request it before giving the withdrawal order, not afterwards.
I am a US citizen: can the United States still tax me?
Yes. The treaty includes a nationality clause, the saving clause, by which each State can tax its residents and, by reason of citizenship, its citizens, as if the treaty had not entered into force. A US citizen resident in Spain continues to file their return with the IRS for that withdrawal.
The practical effect surprises almost everyone: when the United States taxes based on that clause, Spain does not apply the international double taxation deduction in the income tax return. It is the United States that has to eliminate the double taxation, with the foreign tax credit on your American return. Whoever does it the other way around, subtracting in Spain what was paid there, exposes themselves to a tax assessment.
There are two nuances that change the result. The first: pensions paid for services rendered to the US State, the case of the federal civil servant, can only be subject to taxation in the United States, unless the person receiving them resides in Spain and also has Spanish nationality, because then the treaty attributes taxation exclusively to Spain. This is exactly the case of the Spaniard who worked for the US Administration and has returned. The second: if you are neither a US citizen nor a US resident, for example a returning Spaniard, the nationality clause does not affect you, your withdrawal is taxed only in Spain and you must submit form W-8BEN to the plan's management company so that they do not apply the 30% withholding tax at source.
Do I have to include the 401(k) or the IRA in form 720?
The starting rule of the AEAT is that the consolidated rights of a foreign pension plan are not reported as long as the contingency that gives the right to collect does not occur, that is, retirement, disability or death. Once the contingency has occurred, it is reported, for the withdrawal value or as an income established in your favour.
The exception eats up a good part of the rule: if the contract conditions allow withdrawal in terms similar to those of a life insurance policy, there is an obligation to report from the moment that right of withdrawal exists, without waiting to retire. The Directorate-General for Taxes applied this criterion to an IRA and a Roth IRA of a resident in Spain and concluded that both must be declared. It makes sense: an IRA and a Roth IRA usually allow you to withdraw the money at any time, even if the United States penalises withdrawal before the age of 59 and a half. A 401(k) opened with an active employer, on the other hand, normally does not allow it.
The threshold is €50,000 per block, and this fits into the block of securities, rights, insurance and income. Once filed one year, it is only filed again if that block increases by more than €20,000 compared to the last declaration or if you cease to be the owner of something that was included. The deadline runs from 1 January to 31 March of the following year and does not allow for extensions. Managora checks if you are obliged with your actual balances and files form 720 for you.
What about wealth tax?
The balance of a 401(k), an IRA or a Roth IRA does not enjoy the exemption that the Ley del Impuesto sobre el Patrimonio (Wealth Tax Law) recognises for the consolidated rights of Spanish pension plans. The Directorate-General for Taxes has expressly stated this: they enter your wealth and are calculated by their withdrawal value as of 31 December.
Whether or not this translates into a tax quota depends on the exempt minimum and the allowances of your autonomous region, which are not the same throughout Spain, and on the specific regulations of the Basque Country and Navarre, which have their own tax and not a subsidised version of the state one. Above 3 million euros of net wealth, the temporary solidarity tax on large fortunes also applies, which is state-wide and is filed in July.
This is the point that generates the most unexpected bills for the American who settles in Spain with a large retirement plan: a balance that in their country does not appear in any wealth tax does count here. It is advisable to calculate it before moving your residence, not during the first income tax campaign. Managora reviews your complete case, classifies each product, calculates the income tax and files the corresponding forms. You can see the updated amount of each service on its file.
Step by step
- 1
Determine your tax residence for the financial year(Before withdrawing anything)
Days of stay, where the core of your economic interests is and where your family lives. If the United States also considers you a resident, the tie-breaker rules of the treaty apply. This step decides everything else, so it is done before moving a single dollar.
- 2
Ask the US management company for the plan documents(As soon as possible: it is what takes the longest to arrive)
Plan document or contract, balance as of 31 December, withdrawal value, contribution history and, for the year you collect, form 1099-R. Without the contract the income cannot be classified, and without the contribution history you will be overtaxed on a Roth IRA withdrawal.
- 3
Submit form W-8BEN if you are not a US person(Before the first collection. It is valid, as a general rule, until the last day of the third calendar year following its signature)
It is submitted to the plan's management company, not to the IRS, and proves that you reside in Spain to apply the treaty and avoid the 30% withholding tax at source. To benefit from the treaty, it is enough to state your Spanish tax identification number in the foreign tax identification number box: you do not need to process an ITIN or any other US number.
- 4
Plan the withdrawal calendar(In the financial year prior to collection)
A capital withdrawal from an employment-linked plan enters the general base of a single financial year in full and triggers the marginal rate. Spreading it over several years, or combining it with the collection of the Roth IRA that goes to the savings base, legitimately changes the bill.
- 5
Classify the income and calculate the income tax(When preparing the return)
Employment income or investment income according to the contract, conversion to euros at the exchange rate on the date of collection and, if applicable, international double taxation deduction. If the United States taxed under the nationality clause, the correction is not made in Spain.
- 6
File form 100(From April to 30 June of the year following the financial year; the exact date is set by the annual order)
The annual income tax return, with the withdrawal already integrated into the corresponding base and with foreign withholdings and taxes documented.
- 7
Review form 720 and, if applicable, wealth tax(Form 720: from 1 January to 31 March. Wealth tax: the same deadline as the income tax return)
Check if the plan allows withdrawal or if the contingency has already occurred and if the block of securities, insurance and income exceeds €50,000. Add the withdrawal value to your wealth as of 31 December and look at the exempt minimum of your autonomous region.
A worked example
You are a tax resident in Spain in 2026, you do not have US citizenship or a green card and you are retired. You withdraw €40,000 at once from your former employer's 401(k) and €30,000 from your Roth IRA, to which you had contributed €20,000 over the years. You submitted form W-8BEN on time, so the United States does not withhold anything at source.
- 401(k): the €40,000 is employment income and goes in full to the general base. The 40% reduction for Spanish plans does not apply, so it is added to your other income for the year and taxed at your progressive scale, which depends on your autonomous region.
- Roth IRA: income = €30,000 collected minus €20,000 contributed = €10,000, which is investment income.
- Savings base, first bracket: €6,000 at 19% = €1,140.
- Savings base, second bracket: the remaining €4,000 at 21% = €840.
- Savings quota: €1,140 + €840 = €1,980.
For the Roth IRA you pay €1,980, although that same withdrawal in the United States would have paid nothing. The €20,000 of contributions are not taxed, provided you can prove them. The €40,000 from the 401(k) is integrated in full into the general base and taxed at your marginal rate, so withdrawing that part over two or three financial years is usually much cheaper than doing it all at once.

Official forms and where it is filed
Frequently asked questions
Is it advisable to withdraw it all at once?
Almost never, if the plan is linked to employment. Everything collected enters the general base of a single financial year and pushes your marginal rate upwards, without any reduction to cushion it. Spreading the withdrawal over several years is legitimate and usually lowers the bill. Managora simulates the calendar before you give the order to the management company.
I have had 30% withheld in the United States, do I recover it in the Spanish income tax return?
If the treaty attributed taxation only to Spain, that withholding is not corrected here with the double taxation deduction: it is claimed from the US tax authorities by filing the corresponding return there. That is why the W-8BEN, submitted before the first collection, saves a year of paperwork and money sitting idle on the other side of the Atlantic.
I did not file form 720 at the time, what can happen to me?
It is an informative return, with no quota to pay, but failing to file it is penalised. Following the ruling of the European court that struck down the previous regime, the general penalty regime for informative returns applies and undeclared income is no longer imprescriptible. Regularising on your own initiative, before the requirement arrives, is still much cheaper than waiting. Managora prepares the filing and, if necessary, that of the pending years.
Do I have to declare the plan even if I have not withdrawn anything?
Not in the income tax return: without collection there is no income. In form 720 yes, if the plan allows you to withdraw it or the contingency has already occurred and the block of securities, insurance and income exceeds €50,000. And in the wealth tax as well, for the withdrawal value as of 31 December, if you are obliged to declare it according to the rules of your autonomous region.
What happens to my 401(k) when I pass away?
If the 401(k) is still linked to your employment, what your beneficiaries collect upon your death does not go to inheritance and gift tax: benefits from pension plans and their alternative systems are expressly not subject to that tax when they are integrated into the recipient's income, so each beneficiary declares them in their income tax return as employment income, in the year they collect them and at the rate of their general scale. A product not linked to employment and comparable to a life insurance policy, such as an IRA contracted privately, is different: inheritance and gift tax may apply there, whose tariff, reductions and allowances depend on the competent autonomous region and are not the same throughout Spain. The classification depends on the plan contract, so it is advisable to review it before accepting one route or the other. Furthermore, the US management company usually requires specific and translated documentation to release the balance. Managora classifies the product, calculates the corresponding taxation and coordinates both parties.
I am under the impatriate regime, am I exempt?
Probably yes, but it is advisable to check it before moving anything. Under the special regime you are taxed by the rules of the non-resident income tax, and the criterion of the Directorate-General for Taxes is that a pension or a withdrawal from a foreign plan that remunerates past work does not fall within the rule that considers all the impatriate's employment income to be obtained in Spain. As it is not understood to be obtained in Spain, that collection is not taxed here during the regime. It is a criterion that depends on the plan contract and how the income is classified, so Managora reviews it case by case before you apply for the regime or give the withdrawal order.
