They are usually in a drawer, or a safe deposit box, or an envelope your father left you. Series EE bonds bought through payroll deduction in the 1990s. I bonds bought in a panic in 2022 when inflation was frightening. A few thousand dollars, or a few hundred thousand. Nobody thinks of them as a tax problem, because for thirty years they have done nothing at all — no statements, no 1099s, no decisions. That silence is the problem.
This page is for American retirees and financially independent movers relocating on the non-lucrative visa who own US savings bonds. It handles the tax lane; if your question is instead whether the bonds can be used as proof of means for the visa, that is a separate page. It is a companion to our page on US municipal bonds and Treasury interest in Spain, but it is not a repeat of it, and the difference is not a technicality. That page is about bonds that pay you interest every year, where the only question is how Spain taxes each year's coupon. A savings bond pays no coupon at all. Its entire tax life happens in one instant, and everything on this page follows from that.

"Clients bring me spreadsheets of their brokerage accounts and forget the envelope of paper bonds, because those have never once appeared on a tax return. Then a bond from 1996 quietly matures in their first Spanish year and thirty years of American interest lands in a Spanish savings base. Nobody did anything wrong. Nobody did anything at all — that is precisely how it happens."

Why this is not the Treasury bond page
It is worth being precise about the instrument, because Americans use "Treasuries" loosely and the two things behave nothing alike once a border is involved.
A marketable Treasury — a T-bill, note or bond bought through a broker — pays interest on a schedule, generates a 1099-INT every year, and can be sold to anyone. For a Spanish resident the analysis is annual and undramatic: each year's interest is investment income in the Spanish savings base, each year's US tax and Spanish tax meet in the same year, and the foreign tax credit generally has something to work with. That is the subject of our municipal bonds and Treasury interest page, and if that is what you own, read that instead.
A savings bond is a different animal wearing the same flag. It is non-marketable — you cannot sell it, only redeem it with the Treasury. It pays nothing along the way; the interest accrues inside the bond and increases its redemption value. It exists only in a TreasuryDirect account or as a piece of paper. And it has a hard thirty-year life, after which it stops earning entirely. Almost every difficulty below traces back to one of those four features.
The deferral nobody chose
US law gives savings bond owners a choice: report the accrued interest each year as it builds, or defer reporting all of it until you redeem the bond or it reaches final maturity. Deferral is the default. Reporting annually is the election — and it is an election almost nobody makes, because it means paying tax every year on money you have not received.
So the ordinary American savings bond owner has, without ever making a decision, accumulated an asset with decades of untaxed income compounding inside it. A $5,000 EE bond bought in 1996 may be worth several times that today, and none of that growth has ever appeared on a tax return. In the United States this is straightforwardly good: deferral is worth money, and you get to pick the year you take the hit by picking the year you redeem.
Notice what that convenience actually built, though. It built a container. Every year of deferral put another year of income into a box that will be opened exactly once. For as long as you live in one country, a box that opens once is a feature — you choose the moment. The instant a second country acquires the right to tax you, that same box is the entire problem, because a single moment can only fall on one side of a border.
Thirty years of interest, one Spanish tax year
For a Spanish tax resident, interest from a US savings bond is investment income and lands in the Spanish savings base, taxed on a progressive scale running from 19% to 30%. There is no Spanish exemption for US government paper — Spain does not care that the issuer is the Treasury, any more than the United States would exempt a Spanish government bond in the hands of an American.
The rate is not really the point. The concentration is. Because the savings base is progressive, income that would have been taxed at 19% if it had arrived as €4,000 a year for thirty years can be taxed at 27% or 30% when it arrives as €120,000 in one afternoon. The deferral that saved you money in America actively costs you money in Spain, by pushing a lifetime of interest up through every bracket in a single year.
And then the harder question, the one people ask with real indignation: Spain never taxed a cent of this while it accrued. I was in Ohio. Surely Spain only taxes the part earned after I arrived?
Generally, no. Spain does not rebase your assets when you become resident. There is no step-up on arrival, no clock that starts at the airport. When the interest becomes taxable, Spain is generally looking at the whole accrual, including the twenty-eight years of it earned while Spain had no claim on you whatsoever. Readers of our page on selling a US business before retiring to Spain will recognise this instantly: it is the same absence of rebasing that lets Spain tax a founder on gain that accrued entirely in America. The savings bond is the retail version of the same structural fact, and it catches people with $40,000 of bonds rather than $13m of stock.
The date on the bond picks your tax year
Everything above assumes you decide when to open the box. Here is the part that removes even that.
Series EE and I bonds earn interest for thirty years. At the end of that period they reach final maturity: the interest stops, the bond stops growing, and all of the accrued but previously untaxed interest becomes taxable in that year in the United States whether or not you cash it in. Not when you get around to it. Not when you need the money. That year.
Read that again with a calendar next to you. A bond issued in 1996 reaches final maturity in 2026. A bond bought through payroll deduction in 1999 matures in 2029. The bonds an American retiree is most likely to have forgotten about — the oldest ones, bought when they were working, worth the most now precisely because they have compounded the longest — are the ones maturing right now. If your move to Spain is planned for the same window, the bond and the move are on a collision course that neither of them knows about.
What makes this genuinely dangerous is that nothing happens. There is no cash movement to notice, no redemption to remember, and if TreasuryDirect has an old address or the bond is paper in a drawer, quite possibly no piece of mail either. A taxable event occurs in complete silence, in a year you may not have chosen, in a country you may no longer live in. It is the only item we routinely see where a client can incur a substantial tax liability on both sides of the Atlantic without taking a single action.
The credit that fails on timing, not absence
Regular readers will be expecting the usual conclusion here. In our pages on the Roth IRA, on qualified charitable distributions and on QSBS, the story ends the same way: the United States charges no tax, so there is no US tax for a foreign tax credit to offset, so the Spanish tax stands alone as a pure cost.
The savings bond is not that. Savings bond interest is fully taxable in the United States as ordinary income. There is real US tax. There is something for a credit to work against. On the face of it this is the one American tax-favoured asset that should travel reasonably well.
The failure mode is different, and subtler. A foreign tax credit generally needs the same income to be taxed by both countries in the same tax year. Now put that beside the final maturity rule. The United States taxes the entire accrual in the year the bond matures, whether or not you touch it. Spain, taxing investment income when it becomes payable to you, is looking at a different trigger — and if you leave a matured bond sitting for two years before redeeming it, the Spanish charge can arrive in a year when the US charge is long gone.
Two countries, both correct, both taxing the same interest, in different years — and the relief designed to prevent double taxation quietly does nothing, because it has nothing to match. This is a mismatch of calendars rather than a mismatch of principles, which is exactly why it slips past advisers who are watching the principles. Note the direction of the exposure: it is the one asset on this site where redeeming late can cost you more than redeeming at a bad rate. The Spanish characterisation and timing of a matured-but-unredeemed bond is a genuinely technical question that deserves a real answer for your facts rather than a generalisation from us; what we can say confidently is that the way to avoid needing that answer is not to let the two dates drift apart.
| Marketable Treasury / T-bill | Series EE or I savings bond | |
|---|---|---|
| When you receive interest | On a schedule, every year | Once, at redemption or maturity |
| When the US taxes it | Each year, 1099-INT arrives | At redemption — or forced at final maturity, cash or no cash |
| When Spain taxes it | Each year, same year as the US | Broadly when it becomes payable to you |
| Do the two years line up? | Yes, naturally | Only if you make them |
| Foreign tax credit | Generally has something to work with | Works if the years match; can fail entirely if they do not |
| Can you sell it? | Yes, to anyone | No — redemption with the Treasury only |
| Can you reach it from Spain? | Through your broker, normally fine | Needs a US address of record and a US bank account |
The other asset that walks through the second door
The timing failure described above is not unique to savings bonds. Its cleanest example is a US pass-through entity: America taxes your share of the profits the year the entity earns them, whether or not a dollar is distributed, while Spain — if it reads the entity as a company — taxes nothing until the cash finally comes out years later, and then calls it a dividend. Two ordinary tax systems, two different years, no year in which both bills exist to be set against each other. See your US LLC, S corp and the K-1 after you move to Spain.
A Qualified Opportunity Fund creates another calendar version of the same family: the old US deferral ends no later than 31 December 2026, which can be exactly the year the investor first becomes Spanish resident.
The education exclusion: the Roth trap returns
Many people bought EE bonds with a specific sentence in mind: they are tax-free if you use them for education. That sentence is roughly true in America and mostly false for you.
Section 135 of the Internal Revenue Code excludes savings bond interest from US gross income when the redemption proceeds are used for qualified higher education expenses in the same year. The conditions are strict even domestically. The bond must have been issued after 1989 and the owner must have been at least 24 years old at issue — which disqualifies the bonds your parents bought in your name as a child. The expenses must be for you, your spouse or your dependent, which quietly defeats the most common plan of all: grandparents cannot simply redeem bonds for a grandchild's tuition unless that grandchild is their dependent. And the exclusion phases out on income, for 2026 between $152,650 and $182,650 of modified AGI for a married couple filing jointly, and between $101,800 and $116,800 for a single filer.
Suppose you clear all of that. Now you are a Spanish resident, and here the familiar trap closes. The §135 exclusion works by removing the interest from US income. No US income means no US tax. No US tax means no foreign tax credit. And Spain, which has never heard of §135 and has no education exclusion of its own for a US instrument, taxes the interest in the savings base in full. The exclusion working perfectly is what leaves the Spanish tax completely exposed — the better the American planning, the worse the Spanish outcome. If that sentence sounds familiar, it is the identical mechanism we describe for the Roth IRA and the QCD. A US exclusion is not a shield when a second country is doing the taxing; it is a hole where your credit should have been.
One point where we can be more helpful than the usual advice. §135 borrows its definition of an eligible educational institution from §529(e)(5), which reaches institutions outside the United States that participate in the US Department of Education's federal student aid programmes — several hundred foreign universities qualify, and a number of Spanish ones do. So "my grandchild is studying in Madrid, therefore the exclusion is dead" is not automatically right. Check the Department of Education's Federal School Code list for the specific institution before assuming either way. It changes the US analysis. It does not, unfortunately, change the Spanish one.
The state-tax benefit you already lost
There is a second reason people hold savings bonds, and it is worth retiring the idea explicitly rather than leaving it in the back of your mind.
Savings bond interest is exempt from state and local income tax. For a retiree in New York or California this was a genuine, quantifiable benefit and often the whole reason the bonds were bought instead of a CD. It is also, obviously on reflection, a benefit that only exists while you are subject to a US state income tax.
If you are doing this properly, you are severing state tax residency as you leave — the subject of our guide to cutting US state tax residency before moving to Spain. The moment you succeed at that, the savings bond's state exemption becomes worth exactly nothing, because there is no state tax for it to exempt you from. Meanwhile Spain has a regional tax layer of its own, and it grants no such exemption to anybody. So one of the two reasons you owned these bonds evaporates on the same day your residency does, and the other reason — deferral — has just been converted from an advantage into a concentration risk. It is fair to ask what the asset is still doing for you.
TreasuryDirect, a US address and a drawer full of paper
Now the unglamorous part, which is the part that actually generates the panicked email eighteen months after the move.
US citizens may own savings bonds while living abroad. But TreasuryDirect, the only way to hold electronic bonds, requires an account owner to have a United States address of record and an account at a US financial institution that will accept ACH debits and credits. The system was built on the assumption that you are in America. Nothing about it accommodates a client in Torremolinos gracefully.
The practical failure chain is predictable. You move. You close the US bank account because you no longer need it, or the bank closes it because you no longer have a US address. You update your address with everyone. Now the ACH link that TreasuryDirect needs in order to pay you is broken, and repairing it from Spain means notarised forms — a US consulate or embassy notary is generally acceptable, which helps, but it is a trip to Madrid and a wait, not a mouse click. The asset has not become unreachable. It has become annoying enough that people leave it — and leaving it is precisely what triggers the maturity problem above.
Paper bonds are worse. They are redeemed in person, at a US bank, with identification, by someone standing in the United States. If you have an envelope of paper EE bonds and you are moving permanently to Spain, the honest question is not how you will manage them from abroad but whether you should convert or redeem them while you are still standing in the country where that is a ten-minute errand.
So the checklist is short and boring and worth more than any of the analysis above: keep a US bank account open through the move; keep a usable US address of record; convert paper to electronic or redeem it before you go; and make sure TreasuryDirect can actually pay you before you need it to. This sits naturally alongside the banking and administrative work in our first 90 days in Spain checklist — but unlike most of that list, this part has to be done on the American side, before you fly.
Modelo 720 and wealth tax
Two Spanish obligations touch the bonds themselves rather than the income.
Savings bonds are foreign securities held by a Spanish resident, so they fall within the reporting categories of Modelo 720 once the relevant thresholds are met. The value to report is the bond's redemption value, not its face value — a distinction that matters enormously with these instruments, because a bond with $5,000 printed on it may be worth $20,000. Using the face value is one of the easier ways to file an inaccurate return while believing you have complied, and this is exactly the type of asset people forget to include at all, since it produces no statements to prompt them.
The same redemption value goes into the wealth tax analysis, which varies by autonomous community, plus the state solidarity tax above €3m. There is a quiet unfairness worth naming here: the accrued interest inside the bond increases your wealth-tax base every year even though you have never been taxed on it as income and have never received it. You are paying an annual tax on money you cannot spend, and will later pay income tax on the same money when it finally comes out.
Read the issue dates before you pick a move date
Which brings us to the decision, and to the reason we treat this as a relocation question rather than an investment one.
The strongest option is usually the simplest: redeem before you become a Spanish tax resident. Do it while you are still solely a US taxpayer and the entire accrual is taxed once, in one country, at your US rate, with no Spanish overlay and no credit to coordinate. Better still, the years between a final salary and the start of pensions and required distributions are often the lowest-income years of an American's adult life. A bond box opened in that window can be opened cheaply. That is not a coincidence you should waste.
It is a calculation, not a rule. Redeeming early costs you the return the bond was still earning, and if it has years left and a good fixed rate that is a real sacrifice. There is a case for holding, particularly for I bonds bought in a high-inflation year — but the case has to be made with the maturity dates in front of you, not against a vague sense that deferral is good.
Whatever you decide, remember what makes this asset unusual. Spain has no split-year treatment: arrive in March and you are generally resident for the whole calendar year, so "before you move" means before 1 January of your arrival year, not before your flight. And the bond does not wait for your decision — final maturity happens on schedule with or without you. Every other item on our site is something you can still act on at the airport. This one has a date printed on it. Find the dates, then plan the move around them.
If the move has already happened and the bonds came with you, nothing here is fatal — but do the three things that stop it compounding: list the issue dates and work out which bonds have already matured or will mature soon, repair the TreasuryDirect and US banking plumbing before you need it, and get the Spanish reporting right at redemption value rather than face value. Coordinate it with your US adviser and your US filing obligations, because this is one of the rare items where the two returns have to be looked at together or the relief simply will not work.
Frequently asked questions
Does Spain tax US savings bonds?
Yes. Spain taxes its residents on worldwide income, and interest from a US savings bond is investment income for a Spanish tax resident, taxed in the savings base at rates running from 19% to 30%. There is no Spanish exemption for US government paper of any kind. The particular difficulty with EE and I bonds is not the rate but the concentration: because US rules let the interest accumulate untaxed for up to thirty years, the whole accrued amount arrives in a single moment rather than year by year, and if that moment falls in a Spanish tax year Spain is looking at all of it at once.
Spain never taxed the interest while it accrued. Does Spain still tax the full amount?
Generally yes, and this surprises people who expect a fresh start on arrival. Spain does not rebase your assets when you become resident. A bond bought in 1998 that accrued interest for decades while you lived in Ohio does not arrive in Spain with its history reset; when the interest becomes taxable, Spain is generally looking at the whole accrual, including the part earned long before Spain had any claim on you. This is the same feature that makes a pre-move business sale so expensive, and it is why the calendar matters more than almost anything else.
What happens at final maturity if I do not cash the bond?
Series EE and I bonds earn interest for thirty years and then reach final maturity. At that point the interest stops, and all of the accrued but previously untaxed interest becomes taxable in that year in the United States whether or not you cash the bond in. You do not need to do anything, receive anything or decide anything. This is the feature most likely to catch a retiree in Spain: the bond has a date printed on it that will select a tax year for you, and a bond issued in 1996 reaches that date in 2026.
Will the foreign tax credit protect me?
Sometimes, and less reliably than with an ordinary bond. Unlike a Roth distribution, savings bond interest is genuinely taxable in the United States, so there is real US tax for a credit to work against. The problem is timing rather than absence. If the United States taxes the accrual at final maturity in one year and you redeem the bond and trigger the Spanish charge in a later year, the two taxes fall in different tax years, and a credit generally needs the same income taxed by both countries in the same year to function. Both countries can be entirely correct and the relief can still fail. Aligning the years is the planning point, and it should be modelled with your US and Spanish advisers.
I planned to use my savings bonds tax-free for a grandchild's education. Does that work in Spain?
Usually not, for several stacked reasons. Section 135 excludes savings bond interest from US income when it is used for qualified higher education expenses, but the bond must have been issued after 1989 to an owner aged at least 24, the expenses must be for you, your spouse or your dependent (which typically defeats the classic grandparent plan unless the grandchild is your dependent), and the exclusion phases out on income. Most importantly for a Spanish resident: if the exclusion works, there is no US tax, and therefore no US tax for a foreign tax credit to offset, while Spain still taxes the interest. That is exactly the Roth pattern. The exclusion working perfectly in the United States is what leaves the Spanish tax fully exposed.
Can I still use TreasuryDirect from Spain?
It is awkward. TreasuryDirect requires an account owner to have a United States address of record and an account at a US financial institution that accepts ACH debits and credits. US citizens may own savings bonds while living abroad, but the account plumbing assumes you are in the United States. Losing your US address or your US bank account can leave you holding an asset you cannot conveniently reach. Paper bonds are worse: they are generally redeemed in person at a US bank with identification. Sort out the US banking arrangements and your address of record before you move, not after.
Should I cash my savings bonds before moving to Spain?
Often it is worth serious consideration, but it is a calculation rather than a rule. Redeeming while you are still solely a US tax resident means the whole accrual is taxed once, in the United States, at your US rate, with no Spanish overlay at all — and if you are in a low-income year between salary and pensions, that rate may be modest. Against that, you lose whatever return the bond was still earning and you may be accelerating tax you could otherwise defer. What you should not do is drift into your first Spanish tax year without knowing the issue dates. Read them first, then decide.
What value do I report on Modelo 720 — the face value or what it is worth now?
The redemption value, not the face value. This matters more with savings bonds than with almost any other asset, because a bond with $5,000 printed on the front may be worth several times that after decades of accrued interest. Reporting the printed number is a common way to file an inaccurate return while believing you have complied. The same redemption value feeds the wealth-tax analysis, which means the accrued interest increases your Spanish wealth-tax base each year even though you have not received it and have not yet been taxed on it as income.
