Some States Keep Taxing You After You Leave America: The Sticky-State Problem, Explained

Most Americans who move abroad assume they are leaving the whole American tax apparatus behind, and they are only half right. The federal government follows you forever, taxing your worldwide income for as long as you hold a US passport. But people more or less expect that by now.

What almost nobody expects is that a handful of US states will also keep taxing you, sometimes for years after you have physically left the country, unless you cut your ties to them in exactly the right way. These are the so-called sticky states, and getting caught by one means paying state income tax on your worldwide income while living on another continent, entirely because you did not properly close the door behind you on your way out of the country. So here is what the sticky-state problem actually is, which states are the worst offenders, why simply moving abroad is not enough to escape them, and how careful expats break free. It is one of the most avoidable tax mistakes an American abroad can make, and one of the most expensive to fix after the fact.

What follows is why states tax differently from the federal government, which states are sticky, why moving abroad does not end it, the bridge move and the clean break that do, and the catches to watch.

Why States Tax Differently From the Feds

To understand the sticky-state trap you have to grasp one crucial distinction, because it is the root of the whole problem. The federal government taxes on the basis of citizenship, which is why it follows you anywhere on earth. States do not work that way. A state taxes you based on residency and, more precisely, domicile, meaning your permanent legal home, the place you fundamentally belong and intend to return to. This difference matters enormously, because it means that leaving a state’s tax net is, in principle, possible in a way that leaving the federal one is not. You can, with enough care, stop being a resident of a state; you cannot stop being a citizen of the country without formally renouncing, which almost nobody does.

For most states, this works cleanly and in your favor. You establish that you no longer live there, you sever your connection, and the state stops taxing you, because its claim rests on residency and you are no longer a resident. The nine states with no income tax at all, Florida, Texas, Nevada, Washington, and their peers, are the simplest of all, since they were never taxing your income to begin with and could not care less where you go. The trouble arises only with a specific group of states that interpret domicile aggressively and make it genuinely hard to prove you have left, treating your departure with suspicion and clinging to their claim on you long after you have gone. Those are the sticky states, and the difference between them and the rest is not the basic principle, which is the same everywhere, but how stubbornly they apply it and how much evidence they demand before they will let you off their rolls. Two people leaving the country in identical circumstances can face wildly different outcomes purely because one last lived in Texas and the other in California.

The States That Won’t Let Go

The sticky states are a fairly well-known group, and if your last American home was in one of them, you need to pay attention. The most frequently named are California, New Mexico, New York, South Carolina, and Virginia, with a few others like Massachusetts and Maryland sometimes added as moderately aggressive. These are the states that fight hardest to keep former residents on their tax rolls, that demand extensive proof before they accept you have left, and that will audit you years after the fact and argue you never truly abandoned your domicile.

California, predictably, is the most aggressive of all, and it deserves special mention because so many expats come from it. California taxes its residents on their worldwide income, and it does not recognize the federal Foreign Earned Income Exclusion, which means it can tax income that your federal return exempted entirely, a nasty surprise for anyone who assumed the federal break covered them everywhere.

Virginia is notably stubborn too, taking the position that you remain a Virginia domiciliary until you establish a new domicile somewhere else, and simply moving abroad does not count as establishing a new one. New Mexico and South Carolina apply similar logic and demand similar proof, and New York runs its own aggressive residency tests, distinguishing between domicile and mere statutory residency and pursuing both. Each has its own quirks, but the family resemblance is unmistakable, and none of them lets go easily. The common thread is that these states start from the assumption that you are still theirs and put the burden squarely on you to prove otherwise, which is a very different posture from the states that simply wave you goodbye. They are not doing anything illegal; they are simply enforcing their domicile rules to the hilt, because a departing high earner is real revenue they would rather not lose.

Why Moving Abroad Is Not Enough

Here is the counterintuitive heart of the problem, the thing that catches people out: moving abroad, all by itself, may do nothing to end your residency in a sticky state, and understanding why requires understanding the concept of domicile. Domicile is legally sticky by its very nature: once established, a domicile continues until you establish a new one somewhere else. You do not lose a domicile simply by leaving it; you lose it by replacing it. This is the single sentence that explains the entire trap, and the one most people never hear until it is too late. And this is exactly where moving abroad falls into the trap, because a foreign country is not a US state, and the sticky states take the view that moving overseas does not establish a new domicile in the way that moving to another state would.

The result is a genuine catch. You pack up, leave California or Virginia, move to Spain, and settle into your new life, but in the eyes of your former state you may never have replaced your domicile at all, because you moved to a country rather than to another state, so your old domicile simply continues, and with it your obligation to pay state income tax on your worldwide income. Expats discover this the hard way, often years later, when a letter arrives from a state they thought they had left, asserting that they still owe, frequently with penalties and interest stacked on top of the original tax. By then the sums can be considerable, and the paperwork to fight it, gathered from another continent, is its own ordeal.

And the burden of proof is on you, not the state; it is up to you to demonstrate, with documentation, that you genuinely severed your ties and ended your domicile, and a sticky state that is not convinced will keep right on taxing you. This is why the naive assumption, that leaving the country obviously ends state taxes, is so dangerous: for a sticky state, leaving the country can be precisely the move that fails to end them. The very act people think frees them is, for these states, the act that does not.

What Actually Counts as a Tie

Since the whole game with a sticky state is proving you have genuinely ended your domicile, it helps to know what those states actually look at, because domicile is judged on a web of connections rather than any single fact. There is no one box to tick; instead, a tax authority weighs the whole picture of where your life is anchored, and the more threads that still run back to the old state, the stronger its argument that you never really left.

The connections that matter are the ordinary furniture of a settled life. Where is your home, and do you still own one in the state? Where is your driver’s license issued, and where are you registered to vote? Where are your bank and investment accounts, your doctors and dentists, your professional licenses, your club and gym memberships? Where is your mail sent, where are your cars registered, and where does your family live? Where do you actually spend your time when you are in the United States at all?

Each of these is a thread, and a sticky state examining your case adds them up: a person who kept a house, a license, a voter registration, and a local bank in California looks, to California, like a Californian who is merely traveling, however long they have been in Spain. The lesson is that severing domicile is not a single act but a deliberate dismantling of all these ties at once, and the person who cuts some but carelessly leaves others hands the state exactly the evidence it needs. Knowing the list in advance is what lets a careful mover cut every thread rather than discovering, in an audit years later, the one they forgot.

The Bridge Move and the Clean Break

Fortunately, the problem is entirely solvable with the right steps, and expats who plan ahead have two main strategies, both of which come down to properly ending your domicile rather than just leaving. The first and cleanest is the bridge move: before you leave the United States, establish domicile in a no-income-tax state, Florida, Texas, Nevada, and South Dakota being the popular choices. By moving your legal home to a no-tax state first, you replace your sticky-state domicile with a new one that the old state will actually recognize, since sticky states are far more willing to accept that you moved to another US state than that you vanished into a foreign country. Spend a couple of months genuinely establishing yourself there, get the driver’s license, register to vote, and then move abroad from that state, and you have cleanly broken the chain. The point is that when a sticky state later asks where you went, you have a clear answer that it recognizes: not merely away, but to a specific new legal home in another state.

The second strategy, for those who cannot or will not do the bridge move, is to sever every possible tie to the sticky state so thoroughly that even an aggressive tax authority cannot argue you remain domiciled there. That means selling or renting out your home, surrendering your state driver’s license, cancelling your voter registration, moving your bank accounts, resigning from local memberships, and generally erasing every thread that ties you to the place, while documenting all of it meticulously, because you may have to prove it years later. The nine no-income-tax states function as the escape hatches in both strategies, the safe harbors a departing expat routes through or toward, precisely because they have no interest in taxing you and no reason to chase you. Establishing a foothold in one of them before you go is, for someone leaving a sticky state, one of the highest-value pieces of pre-departure housekeeping there is. Whichever path you take, the essential insight is the same: you do not escape a sticky state by leaving it, you escape it by properly and provably ending your legal home there, and doing so before you go is far easier than trying to fix it from abroad.

The Catches to Watch

A few important catches remain even for those who break residency cleanly, and an honest account has to include them. The first is that state-sourced income stays taxable no matter how thoroughly you have left. If you keep a rental property in your old state, the rental income it generates remains taxable there; business income and certain kinds of deferred compensation, like stock options or restricted stock earned while you were a resident, can likewise remain within the state’s reach even after you have severed your residency entirely. The state’s view is that the income was earned on its soil, so it gets to tax it whenever it is finally paid, regardless of where you have since moved. Cutting your domicile ties ends the state’s claim on your worldwide income, but not its claim on income that physically arises within its borders. So a clean break frees your pension and your investments from the state, but the rent from the house you kept back there stays on its books.

The second catch is that holding onto property in a sticky state can undermine your whole effort to leave, since a home kept in the state is exactly the kind of tie an aggressive tax authority points to as evidence that you never really abandoned your domicile.

This puts expats who want to keep a US home in a genuine bind, and it is one of the many places where professional advice earns its keep. The practical wisdom that emerges from all of this is straightforward: if your last US home was in a sticky state, do not assume that moving abroad ends your state tax obligations, plan your exit before you leave, not after, consider routing through a no-tax state, sever your ties as completely as your circumstances allow, keep thorough records of everything, and get advice from someone who understands both federal and state tax rules for Americans abroad. Do that, and the sticky-state problem becomes a solved problem rather than an expensive surprise. It is entirely within your control, but only before you go; once you are abroad with the ties still in place, you are playing defense against a state that holds most of the cards. Ignore it, and you may find that the state you thought you left behind is the one part of America that refuses to let you go.
