5 US states that keep taxing you long after you’ve left the country
Here’s an assumption that trips up a lot of new expats: cross an ocean, and your home state stops caring what you earn. Five states disagree, and how long you’ve been gone barely matters to them. If you built your life in California, New York, Virginia, South Carolina, or New Mexico before you left, that state may still call you a resident — and still expect a return on income you earned an ocean away.
Why some states just won’t let go
Most states check where you physically live before deciding what you owe. The five above check something trickier: domicile, basically your legal home base, the place you’re presumed to intend to return to, even while you’re living somewhere else entirely. Move to Lisbon for three years and never set foot back in Sacramento, and California can still argue that’s where you’re domiciled if you never formally cut the cord.
Sound like a technicality? It’s the exact technicality that’s landed plenty of expats an audit notice years after they assumed they were done with their old state for good.
1. California — the strictest of the bunch
California has a narrow legal escape hatch called the 546-day safe harbor, and it’s stricter than it sounds. To qualify, you need at least 546 consecutive days outside the state under an actual employment contract, no more than 45 days back in California per year, less than $200,000 in intangible income, and a spouse who also qualifies or lives outside the state.
Self-employed? Freelancing? Retired? None of that counts — the safe harbor only exists for people sent abroad by an employer with a signed contract, which rules out a huge share of the Americans actually moving overseas right now. And here’s the part that really stings: California doesn’t recognize the federal Foreign Earned Income Exclusion or the foreign tax credit, so money you’ve already paid tax on abroad can get taxed again by the Franchise Tax Board.
2. New York — two separate ways to get caught
New York runs two independent tests, and you have to clear both to walk away clean. The first is domicile: if New York was your legal home base and you go abroad for work, study, or even just an extended adventure, the state says you keep your New York domicile unless you can clearly show you intend to stay abroad permanently and never return.
The second is the statutory residency test, and it can catch you even if you win the domicile argument. Keep an apartment or any place you could stay in New York and spend 184 days or more there in a calendar year — partial days included — and you’re a statutory resident anyway, worldwide income and all.
3. Virginia — no direct route out
Virginia’s rule is almost sneaky in its simplicity: you can’t go straight from Virginia to a foreign country and expect your Virginia domicile to end. The state requires you to establish domicile in another US state first, which means movers who go straight from Richmond to Rome are technically still Virginia residents, tax bill and all, no matter how long they’ve been gone.
Psst — thinking about actually doing this? I put everything I know about leaving the U.S. for good into one no-fluff guide: visas, jobs, country picks, the works — grab it here.
4. South Carolina — proof, not just distance
South Carolina doesn’t accept “I moved abroad” as evidence on its own. It wants proof you’ve built a new domicile somewhere else — a new driver’s license, new bank accounts, a home you actually live in — and until that paperwork exists, the state can keep treating you as a resident no matter how many stamps are in your passport.
5. New Mexico — same story, different state line
New Mexico runs roughly the same playbook as South Carolina: distance alone doesn’t cut it. Without a documented new domicile, the state can still treat your move abroad as a long vacation rather than a legal departure — and tax you accordingly.
How to actually cut ties before you go
The fix, across all five states, is basically the same: sever the ties before you leave, not after. Get a driver’s license somewhere else, register to vote elsewhere, close local bank accounts, sell or rent out property, and keep your visits back under whichever day-count limit applies to you.
If you don’t already have a new US address lined up, a few states are set up specifically to make this easy — I broke down the three that long-term nomads actually use to solve this exact problem here — and picking one before you fly out can save you an ugly letter a few years down the line.
My honest take? Do the paperwork before you leave, not after your first confusing tax bill shows up. It’s tedious, sure, but it’s a fraction of the hassle an audit is.
So which of these five is going to complicate your move — or did you already have to fight one of these battles?
