A large and often overlooked slice of US applicants for the non-lucrative visa are not private-sector savers — they are retired federal civil servants, foreign-service officers and career military. They come to Spain with a familiar set of accounts: a FERS or CSRS annuity, perhaps military retired pay, Social Security, and the Thrift Savings Plan (TSP), the federal government's own defined-contribution retirement plan. Because everything in that list came from government service, the natural assumption is that all of it is "US money" the US taxes and Spain leaves alone. For the annuity and the retired pay, that assumption is broadly right. For the TSP, it is the single most expensive thing a federal retiree can get wrong.
This page is deliberately narrow. Our note on the US–Spain tax treaty for retirees maps the whole treaty; our page on how US retirement income is taxed in Spain covers the general picture; our note on US public pensions and the Social Security Fairness Act handles the government-service annuity itself; and our page on 401(k) and IRA as proof of income covers the private defined-contribution cousins. If your public-employer account is instead a state or local 457(b) deferred-compensation plan, the evidence is similar but not identical, especially when comparing governmental and non-governmental plans. This page answers one specific question: how the TSP is treated when a federal retiree moves to Spain — both as visa means and as taxable income — and why its "government" label misleads on both. It is general orientation, not legal, tax or investment advice.

"Federal retirees arrive very sure of one thing: 'my pension is only taxed in America.' For the FERS annuity, fine — that is broadly how the treaty works. Then they say the same sentence about the TSP, and that is where I stop them. The TSP is not a service pension; it is an account you filled up, like a 401(k) with a government wrapper. Spain looks at what an account is, not what it is called, and a defined-contribution account it usually taxes. The visa side has the mirror-image trap: people leave the whole TSP as a lump sum and are surprised it reads as savings, not income. Set up the monthly installment and it reads like a pension. The name fools you both times."

The short answer
The Thrift Savings Plan is a defined-contribution retirement account — the federal equivalent of a 401(k) — not a government-service pension. That single fact drives everything on this page. For the visa, it means a static TSP balance reads as savings, not income, until you turn it into recurring installment payments; do that, and it becomes solid means. For tax, it means you should not assume the treaty rule that shields your FERS annuity from Spanish tax also shields the TSP. The annuity is a government-service pension the treaty generally lets the US tax alone; the TSP is far more likely to be a pension "in consideration of past employment" that Spain, as your country of residence, taxes — giving you a credit for the US tax rather than staying out of it.
None of this makes the TSP a problem. It makes it an account that needs a plan before you move: how you will draw it so it works as means, and who will tax those draws once you are resident. The federal retirees who struggle are the ones who assumed "it's government money" answered both questions. It answers neither.
What the TSP is — and is not
The TSP is the retirement savings plan for federal civilian employees under FERS and CSRS and for members of the uniformed services, administered by the Federal Retirement Thrift Investment Board. You choose how much of your salary to defer, the government adds contributions for most FERS employees, and the balance grows in a handful of index-style funds. It has a traditional (pre-tax) side and a Roth (after-tax) side, exactly like a private 401(k). At retirement you can leave it invested, take single withdrawals, set up installment payments, or buy a life annuity through the plan's annuity provider.
What the TSP is not is a defined-benefit pension. Your FERS or CSRS annuity is a promise the government pays you for life based on your years of service and salary — that is a government-service pension in the classic sense. The TSP is a pot you filled and now draw down; its value depends on your contributions and the market, not on a service formula. That difference is invisible in daily life, because both land in the same bank account. But it is exactly the difference Spain's tax system, and the tax treaty, care about — and it is why the two are treated differently once you are a Spanish resident.
The account-based character also explains why the rollover question deserves its own file. Moving the TSP into an IRA may improve account access, withdrawal flexibility and beneficiary planning, but it does not turn future distributions into income Spain ignores. If you are considering that move, read the dedicated guide to rolling a TSP into an IRA before moving to Spain before treating consolidation as automatic. If the TSP reached you as a surviving spouse rather than from your own federal service, use the separate note on inherited TSP beneficiary participant accounts in Spain, because the death-benefit wrapper and second-death rules change the planning question.
The two moments it surprises a federal retiree
The TSP catches federal retirees out at two separate points in the move, and the same misconception drives both. The first is the visa. A retiree with a healthy six-figure TSP feels wealthy and assumes the balance itself proves they can live in Spain. But the non-lucrative visa tests stable means, not net worth, and a lump-sum account with no draw reads like savings — deep but shapeless. The FERS annuity and Social Security read as income effortlessly because they arrive monthly; the untouched TSP does not, until you make it.
The second is the tax bill, usually in the first Spanish filing season. Having correctly learned that the US taxes their FERS annuity alone, the retiree assumes the TSP is in the same box and reports nothing to Spain on it. Then an asesor explains that Spain considers the TSP an ordinary defined-contribution pension and taxes the withdrawals as residence-state income, with credit for the US tax rather than a pass. The relief that applied to the annuity did not travel to the TSP. Getting ahead of both moments — structuring the draw for the visa and settling the tax characterisation before the first filing — is the whole value of planning the TSP rather than assuming it.
Using TSP installments as visa means
The good news for the visa is that the fix is simple and entirely in your hands. The TSP lets you elect installment payments — a fixed dollar amount paid monthly, quarterly or annually, or an amount recalculated each year from life expectancy. A fixed monthly installment, credited to your bank account on a regular date, produces exactly the evidence a means file wants: a bank statement showing a set sum arriving every month, visually indistinguishable from a pension deposit. Set that up before you apply, let a few statement cycles run, and the TSP stops being savings and starts being documented income.
Size the installment comfortably above the household requirement — broadly around 400% of the IPREM for the main applicant plus roughly 100% for each dependent — and remember the payment is in dollars while the threshold is in euros, so build in a margin and document the conversion using the approach in our note on which exchange rate proves your income. Prefer a fixed-dollar installment over a life-expectancy one for the file, because the amount stays identical each month rather than moving with your balance. Many federal retirees do not even need the TSP to carry the means test alone — the FERS annuity and Social Security often clear it — in which case the TSP installment is welcome extra depth rather than the anchor. Either way, the mechanics mirror our page on using a 401(k) or IRA as proof of income.
Article 20 or Article 21? Who taxes the withdrawals
This is the heart of the page. The US–Spain income tax treaty splits retirement money across two articles, and which one your TSP falls under decides who taxes it first. Article 21 (Government Service) covers pensions paid by a state in respect of services rendered to it — the FERS and CSRS annuities and military retired pay — and generally lets the paying state, the US, tax them alone, unless the recipient is both a resident and a national of the other state. That is the rule federal retirees know and rely on. Article 20 (Pensions) covers pensions and similar remuneration in consideration of past employment, and gives the taxing right to the state of residence — Spain, once you live there.
The TSP sits in the uncomfortable gap between the two, and the better-supported reading is that it belongs in Article 20, not Article 21. It is not a service pension the government pays from its own promise; it is a personal defined-contribution account you funded and now draw, closer in substance to a private pension than to the FERS annuity. Spanish practice tends to treat foreign defined-contribution retirement distributions as residence-state pension income, which means Spain would tax your TSP withdrawals and give you a credit for the US tax paid on the same money — not leave the TSP untaxed the way it effectively leaves the government annuity. The characterisation is genuinely contestable, and it can turn on the exact composition of your account and how each payment is structured, which is precisely why it is worth settling with advice rather than by analogy to the annuity.
The TSP versus your FERS or military annuity
It is worth drawing the line cleanly, because the two live side by side in every federal retiree's paperwork and are taxed differently in Spain. Your FERS or CSRS annuity, and military retired pay, are defined-benefit government-service pensions. Under the treaty they are the strong candidates for US-only taxation, and our note on US public pensions in Spain and on military retirement and VA disability covers how they land once you are resident. The TSP, sitting right next to them on the same benefits portal, is a different animal: a defined-contribution account whose Spanish treatment follows the 401(k) logic, not the annuity logic.
The practical takeaway is to stop thinking of your federal retirement as one block and start splitting it: the annuity in one basket (likely US-taxed, Spain relieves), the TSP in another (likely Spain-taxed, US relieves under the credit and saving-clause mechanics), and Social Security in a third with its own treaty rule. A federal retiree who maps the three separately can plan the draw and the credits properly; one who treats them as a single "government pension" will misjudge the Spanish bill on the largest and most flexible of the three. If any part of the picture is a genuinely uniform government pension question, keep it with the annuity pages; the TSP belongs with the account-based retirement pages, and this is the one to plan hardest.
The Roth TSP twist
Many federal employees built a Roth TSP balance, attracted by the promise of tax-free retirement withdrawals. On the US side that promise holds — you paid the tax going in. But Spain is not bound by the American label, and this is the same trap that catches holders of a Roth IRA: a Spanish tax authority may look through the "Roth" wrapper and tax the growth, or the distribution, as ordinary residence-state income once you are resident, because Spanish law has no domestic equivalent that makes those gains permanently tax-free. Two systems can value the same account in opposite ways, and the treaty does not automatically reconcile a US tax-exemption into a Spanish one.
That does not make the Roth TSP a mistake, but it does make "it's Roth, so it's tax-free everywhere" a dangerous assumption to carry across the Atlantic. A Roth TSP needs its own analysis of how Spain will characterise the payments, and the answer can influence the order in which you draw your accounts — a decision that belongs in the pre-move plan, alongside the sequencing questions in our note on the order to draw your US accounts.
Modelo 720 and RMDs once you are resident
Two obligations follow the TSP into Spain regardless of how the withdrawals are taxed. The first is reporting. Once you are a Spanish tax resident, a TSP account held in the United States is a foreign asset that can fall within the Modelo 720 informational return when the relevant balance thresholds are met. Reporting the account is a separate obligation from taxing the distributions: you can owe the report in a year with no withdrawal at all. The second is required minimum distributions. The traditional TSP remains subject to US RMD rules once you reach the applicable age, so the account keeps generating draws — and therefore a Spanish taxable event on each one — whether or not you want the cash, as our note on RMDs for US retirees in Spain explains. The Roth TSP's RMD position tracks recent US changes and is worth confirming rather than assuming.
Holding the account as a non-resident also has practical wrinkles worth checking before you leave — how the TSP or a receiving brokerage treats a US account with a foreign address, and whether a roll-over into an IRA would help or hurt, in the same way we flag for ordinary US brokerage accounts after you move. The wealth of the account itself may also interact with Spain's wealth tax once you are resident, depending on your region and the rest of your balance sheet.
Documents to gather
For the visa, the TSP evidence has to show that a real, recurring payment is arriving. Start with your TSP statements showing the account and its balance, add the installment-payment election or confirmation that sets up the fixed periodic withdrawal, and then supply the piece that does the work: several months of bank statements showing the installment crediting your account on the same date each cycle. A short covering note tying the balance to the monthly figure helps the officer see the depth behind the flow. Foreign documents may need apostille and sworn translation depending on the consulate — check the mechanics in our apostille and sworn translation guide before you file.
For the tax side, the documents you want in hand are different: the split of your TSP between traditional and Roth balances, your annual distribution records, and the US tax paid on each withdrawal, so a Spanish adviser can position the credit correctly. Keep the TSP paperwork separate from your FERS or CSRS annuity and Social Security records, precisely because they are taxed under different treaty articles — mixing them is how the characterisation gets blurred. A file that keeps the account-based TSP and the service pension in separate folders is a file that can be planned properly.

| The TSP account itself (any year) | Foreign asset; possible Modelo 720 report; RMDs continue | Report if thresholds met; expect draws even without needing the cash |
Frequently asked questions
Is my TSP taxed only by the US like a federal government pension?
Probably not, and this is the mistake to avoid. Your FERS or CSRS annuity and military retired pay are government-service pensions that the US–Spain treaty (Article 21) generally lets the US tax alone. But the Thrift Savings Plan is a defined-contribution retirement account funded largely by your own contributions and market growth, closer to a 401(k) than to a service pension. Its treaty character is contestable, and Spanish practice tends to tax private and defined-contribution retirement distributions as residence-state income under Article 20 — meaning Spain would tax your TSP withdrawals, with a credit for the US tax. Do not assume the comfort you have with the FERS annuity carries over to the TSP; have it reviewed before you move.
Can I use TSP payments as proof of means for the non-lucrative visa?
Yes, if you set them up as recurring income rather than leaving the balance sitting. The TSP lets you take installment payments — a fixed dollar amount monthly, quarterly or annually — and a fixed monthly installment credited to your bank account reads on a statement exactly like a pension deposit, which is what a means file needs. A lump-sum TSP balance is treated more like savings and is weaker on its own. Size the installment comfortably above the household threshold and show it already arriving.
Is the Roth TSP tax-free in Spain?
Do not assume so. The Roth TSP is tax-free on the US side because you paid tax on the contributions, but Spain is not bound by the US label and may tax the growth or the distribution as residence-state income once you are a Spanish tax resident, in the same way it can look through a Roth IRA. Because two systems value the same account differently, a Roth TSP needs its own review rather than a blanket assumption that tax-free in America means tax-free in Spain.
Does my TSP have to be reported on Modelo 720 in Spain?
Once you are a Spanish tax resident, a TSP account held in the US is a foreign asset and can fall within the Modelo 720 informational return if the relevant balance thresholds are met. Reporting the account is separate from taxing the distributions; you can owe the report even in a year with no withdrawal. Required minimum distributions from the traditional TSP also continue under US rules once you reach the RMD age, so the account keeps generating both a US filing and a Spanish reporting obligation.
Should I roll my TSP into an IRA before moving to Spain?
It is a question worth asking before you leave, not after, but there is no universal answer. Rolling the TSP into an IRA can simplify withdrawals and investment choice, but it does not change the core Spanish treatment: an IRA is also a defined-contribution account Spain taxes on distribution. The clean version is a direct rollover, planned before Spanish tax residence where possible, after checking access, creditor protection, Roth balances and any old 401(k) company stock. We treat the TSP-to-IRA rollover timing question separately.
