Moving to Colombia does not automatically end your U.S. state taxes. Most states keep taxing you until you formally break residency, and a few, like California and New York, are aggressive about holding on. The key concept is domicile, your one true, permanent home. Until you abandon your old state’s domicile and establish a new one, you can owe state tax on your worldwide income, including your Colombian salary, even if you exclude that income on your federal return.
You moved to Medellin, you are filing your federal return as an expat, and you assume your home state is in the rearview mirror. For many movers, it is not. State residency does not end at the airport, and the states that are hardest to leave are the ones most likely to come looking. For the wider picture, see our guide to U.S. taxes for digital nomads and the tax issues of working remotely from Colombia.
Quick Facts on State Taxes After Moving Abroad
- Moving abroad does not automatically end your state tax residency.
- Most states tax residents on worldwide income, including foreign earned income.
- Sticky states like California, New York, New Mexico, South Carolina, and Virginia are hard to leave.
- No-income-tax states like Florida, Texas, Washington, and Nevada are simple to leave.
- California does not follow the federal exclusion, so excluded income can still be taxed by the state.
- The burden is on you to prove you actually left.
Domicile vs Residency: The Distinction That Matters
Almost every state residency question comes down to two ideas. Domicile is your one true, fixed, permanent home, the place you intend to return to whenever you are away. You can have only one domicile at a time, and it follows you until you replace it.
Residency is broader. You can be taxed as a resident either because you are domiciled in a state, or because you meet a statutory test based on keeping a home there and spending enough days. Crucially, domicile does not end just because you leave. It persists until you abandon it and establish a new one, through both clear intent and real action.
| Domicile residency | Statutory residency | |
| What it means | Your one permanent home is in the state | You keep a home there and spend enough days |
| Measurement (the test) | Where you intend to return, by facts and intent | A permanent place of abode plus over 183 days |
| How to break it | Establish a new domicile and sever ties | Give up the abode or cut your days below the line |
| Example state | California, by facts and circumstances | New York, abode plus over 183 days |
The gold row is the test you have to beat. One turns on where your real home is, the other on a home plus a day count, and you can be caught by either.
The Aggressive States: California and New York
California is the classic sticky state. It has no simple day-count rule for residency and instead weighs your closest connections, with the burden on you to prove you left. A narrow safe harbor treats you as a nonresident if you are outside California under an employment contract for at least 546 consecutive days, but only if you spend no more than 45 days a year in the state and your intangible income stays under $200,000. It applies to employment contracts, not self-employment.
California adds a sharp trap: it does not recognize the federal Foreign Earned Income Exclusion and does not allow a foreign tax credit. A Californian who never breaks domicile can owe full California tax on a Colombian salary that was already taxed in Colombia and excluded federally.
New York taxes you if you are domiciled there, or if you meet its statutory test: a permanent place of abode in New York plus more than 183 days in the state. The abode test is broad, and even an apartment you own and rent out can count. New York also offers a foreign safe harbor built around a 548-day period, with strict limits on days spent in the state.
How to Actually Break State Residency
Breaking residency is deliberate, not automatic. For long-term movers, the cleanest route is usually to end your old domicile by establishing a new one, then cut the ties that say you never left.
- Establish a new domicile, either in Colombia or, very commonly, in a no-tax state like Florida before you go.
- Sever the ties: sell or genuinely lease out the home, change your driver’s license, voter registration, banking, and doctors.
- File a final part-year return in your old state for the year you leave.
- Keep meticulous records, because states can audit your residency many years after you move.
Many expats re-domicile to a no-tax state first because sticky states more readily accept a move to another U.S. state than to a foreign country. A brief flag stop will not survive an audit. The new domicile has to be real.
The Federal Side Comes Too
State residency is only one layer of moving abroad. The same move raises the federal choice between the exclusion and the foreign tax credit, and it brings foreign account reporting on the FBAR and Form 8938 once you open Colombian accounts. Treating the state and federal pieces together is what keeps the whole move clean.
Common Mistakes Movers Make
- Assuming that moving abroad automatically ends state taxes.
- Keeping a home, driver’s license, or voter registration in the old state.
- Relying on a brief flag stop in a no-tax state that an auditor will not believe.
- Forgetting that California taxes income you excluded on your federal return.
- Not keeping day-count and tie-severance records for an audit years later.
- Treating the 546-day or 548-day safe harbor as automatic when the conditions are strict.
- Overlooking a permanent place of abode, like a rented-out apartment, that keeps you a statutory resident.

Leaving a sticky state is fact-specific, and the time to plan it is before or during your move, not after an audit notice. A Personal CPA Tax Resolution Case Analysis reviews your ties and maps the cleanest way to break residency.Start with a Personal CPA Tax Resolution Case Analysis
