The paper trail that proves you really left your state

It is a connection a state reads as evidence of where you really live. A home, a family, a driver's license, a voter registration, bank accounts and professional licenses all count. Together they show which place is the center of your life.

Usually no state relies on one tie alone.

Instead, the weight of the whole picture decides it.

Because states that tax on domicile care about intent, and intent shows in conduct. California asks whether an absence is temporary or transitory. New York asks whether you abandoned your old domicile. Virginia asks whether you took steps to give it up.

However, an overseas address answers none of those questions by itself.

Your remaining state tax ties answer all of them.

That is why the file matters more than the flight.

FTB Publication 1031 gives a partial list. It includes time in California against time elsewhere, where your spouse and children live, your principal residence, your driver's license, vehicle registration, voter registration, bank accounts and professional licenses.

It also covers doctors, accountants, attorneys and social ties, such as clubs.

The FTB's Publication 1031 sets out the full list.

Less than their strength. California says it is the strength of your ties, not just their number, that determines residency, and no single factor decides it. A family home and children in a local school outweigh a gym membership and a credit card.

So cut the strong ties first.

The weak ones matter only when the strong ones are finely balanced.

A tidy list of what you changed, and when, is persuasive evidence in itself.

More than a form. The Tax Department says your domicile does not change until you can show, with clear and convincing evidence, that you abandoned it and established a new one elsewhere. Filing a certificate of domicile or registering to vote in the new place is not enough alone.

Instead, it considers all aspects of your life.

The department's residency FAQs explain the standard.

Something very direct. Virginia Tax gives as an example that a resident who accepts employment in another country is a domiciliary resident, unless appropriate steps are taken to abandon Virginia as the state of domicile. The job alone does not move you.

It also says that moving out and returning within six months generally does not show intent to live elsewhere.

See Virginia Tax on residency status.

That makes the steps you take, not the job title, the deciding factor in Virginia.

It is usually the heaviest tie, so it deserves the most thought. Selling it is the clearest signal. Letting it to an unrelated tenant on a long lease at market rent also shows you no longer keep it for yourself.

By contrast, keeping it empty and furnished points the other way.

Rent from it may keep you filing a nonresident return, which is a separate matter from residency. Our note on keeping your American house covers that side.

Keep the lease, the letting agent's records and the rent statements. They show the house became an investment rather than a home.

It weakens the case considerably. California puts the location of your spouse and children near the top of its list, and New York's Group B counts your spouse and minor children's days in the state. A family left behind makes an absence look temporary.

Sometimes that cannot be helped, for example during a school year.

Then the other state tax ties need to be especially clean.

Record why they stayed and when they will follow, since that timing supports your case.

They can, when the big ones are close. Club memberships, local doctors and advisers appear in the factor lists states publish, and items like a storage unit or a gym add to the same picture. None of them decides a case alone, but together they fill it in.

In our practice, small ties like these come up more often than people expect.

So tidy them up while you are packing anyway.

They are a moderate tie, and they are easy to overlook. California lists the state where you maintain professional licenses among its factors. A license kept active for a career you might resume looks like a plan to come back.

Some professionals need to keep a license for good reasons, such as a future return to practice.

If so, keep it, but make sure the stronger state tax ties are cut cleanly.

Consider placing it on inactive status where your licensing body allows it.

Because several tests count days, and memory is unreliable. California presumes residence above nine months in the state and allows limited return visits under its safe harbor. New York counts days for its statutory resident test and for both of its exceptions for domiciliaries.

Also, any part of a day in New York counts as a day.

Record every visit, with dates and reasons, as it happens.

A simple spreadsheet updated after each trip is enough.

Often you need one, for banks and brokers that will not mail abroad. That is understandable, but an address at a relative's house in your old state still reads as a tie.

Where possible, accept overseas mail or use a mail-forwarding service rather than a family home.

Also check that the address on your tax returns matches where you actually live.

Small details like this are easy to fix and easy to forget.

No. Federal filing follows citizenship rather than residence, so the federal return continues wherever you live and whatever your state decides. State residency affects only the state return, and it has no bearing on the federal filing duty at all.

The two questions run in parallel, and they rarely give the same answer.

Our guide to filing a US return from abroad covers the federal side.

Most states treat you as a part-year resident. You report worldwide income for the part of the year you lived there, and only state-source income for the rest. The move date therefore needs evidence behind it.

A flight record, a new lease and a start date at work usually settle it.

Bonuses and share awards earned partly before the move need care, because states often tax the part earned while you lived there.

Because a state resident abroad can be taxed twice with no relief. California and Virginia give no credit for income tax paid to a foreign country, apart from Virginia's exception for foreign-source pension income. New York's credit covers US states and Canadian provinces, not Britain.

The US-UK treaty covers only federal income tax, as the IRS treaty documents page shows.

So the only reliable protection is not being a resident at all.

Then be realistic about it. A definite plan to return after a fixed posting is exactly what makes an absence temporary under domicile rules, and no amount of paperwork changes that intention.

For people in that position, the safe harbors matter more than cutting ties.

California's employment-contract safe harbor and New York's Group A and Group B exist for this situation, so test against them first.

Usually nobody, until something prompts a question. A state may notice a resident return that suddenly stops, a property that keeps producing income, or a large sale of assets shortly after the move.

Then it asks for the evidence, often years later.

That delay is why the record matters more than the move itself. Your state tax ties are judged on paper.

Work through these in the months around the move, keeping a copy of each document as you go.

Take a couple leaving Richmond for Edinburgh on an open-ended job offer. They sell the house, move the children to a Scottish school, surrender their Virginia licenses and register as overseas voters.

They keep one bank account for convenience and log each trip home. Their file shows a permanent move, so their Virginia domicile should end with it.

Had they kept the house empty and the car registered, the same job would have looked like a posting. This example is illustrative, not advice.

They keep a copy of every document in one shared folder.

Yes, and it still helps, although it is weaker than acting before the move. A tie cut two years later shows intent from that date, not from the day you left, so earlier years remain open to question.

Act as soon as you realize a tie is still in place.

Then note the date, because it may matter for which years a state can claim.

First, changing a mailing address and nothing else.

Second, keeping the house empty in case you come back.

Third, leaving the family behind without tightening every other tie.

Fourth, relying on memory for day counts years later.

Fifth, keeping a storage unit full of furniture in the old state, which quietly suggests you are coming back.

We review your state tax ties before the move, list what to cut and what to document, and prepare the part-year state return alongside your US federal return.
