How a Remote Consultant Untangled a Two-State Residency Problem
Sam's List Editorial | 2026-07-28
This is an illustrative scenario, representative of the kind of multi-state residency work described below. Details are anonymized and figures are for illustration; state rules vary considerably and results are not guaranteed.
The move felt clean. New apartment in August, new clients unaffected, same laptop, same work. Sixteen months later a letter arrived from the old state asserting that the consultant had never stopped being a resident and owed tax on the entire year.
Two state residency taxes are the most common expensive surprise in remote solo work, and the reason is that leaving a state is a legal act with an evidentiary burden, not a logistical one. This representative case study follows an independent consultant billing roughly 240,000 dollars a year who learned that distinction the hard way.
The Problem
The consultant moved in August from a high-tax state to a lower-tax one. Everything about the move looked like a real move. New lease, boxes, a change of address with the post office, a new gym.
Everything about the paper trail looked like a person who had not moved. The old apartment was kept for another eight months because the lease had time left and a sublet seemed like a hassle. The driver's license was never changed. Voter registration stayed put. The primary bank account, the accountant, the dentist, and the doctor were all still in the old state. And there were roughly a dozen trips back over the following year, some for clients, most for family.
Then the filing decision. The consultant filed a single full-year resident return in the new state and nothing at all in the old one, on the theory that residency followed the lease.
The notice from the old state was not arbitrary. From the state's point of view, someone who kept a residence, a license, a registration, a bank, and a doctor there, and who was physically present frequently, looked exactly like a resident who happened to travel.
The Diagnosis
Two separate tests were in play, and conflating them was the original error.
Domicile is where your permanent home is, and it is a facts-and-circumstances determination. It changes only when you both leave a place and demonstrate an intent to make somewhere else your permanent home. States weigh a familiar set of factors: where you keep your home, where your family is, where you are licensed and registered to vote, where your professional and medical relationships are, where your significant belongings are, and where you spend your time. No single factor decides it, which is precisely why a mixed record loses.
Statutory residency is a separate mechanical test that many states apply independently of domicile. It commonly turns on maintaining a permanent place of abode in the state plus being present there for more than a set number of days, frequently 183. A person can be domiciled in one state and still be taxed as a resident by another purely on the day count and the retained apartment.
The consultant had exposure under both. Domicile was arguable but poorly documented. Statutory residency was the bigger risk, because the old apartment was retained and nobody had counted days. Partial days often count as full days under these rules, and that detail alone reverses a lot of confident assumptions.
There was also a sourcing question separate from residency. Some of the work was performed for clients in the old state during those return trips, and income sourced to a state is generally taxable there regardless of where you live.
The Approach
The work, representative of a multi-state cleanup engagement, went in a specific order.
First, reconstruct the day count. Calendar entries, credit card charges, flight and rail confirmations, and cell records were used to build a day-by-day location log for the period in question. This is tedious and it is the foundation of everything else, because no position can be taken without it.
Second, amend the filings to the correct shape. Instead of one full-year resident return, the year of the move became a part-year resident return in each state, with income allocated to the period of residence in each, plus a nonresident return for the old state covering income sourced there in the following year. The resident credit mechanics were applied so the same dollars were not taxed twice by both states, which is what the credit exists to prevent.
Third, build a domicile file going forward, and fix the facts it was supposed to document. License and voter registration changed. The old apartment was released at the end of the term rather than renewed. Banking, medical, and professional relationships moved. A contemporaneous day log became a standing habit rather than a reconstruction project.
Fourth, change the client engagement paperwork so work performed in the old state was identifiable and could be sourced correctly rather than argued about later.
The Outcome
In this representative scenario, the amended filings resolved the assessment to a materially smaller balance, most of which reflected income genuinely sourced to the old state, plus interest. The full-year residency assertion did not survive a documented day count and a corrected filing position.
The honest caveats matter here more than the headline. Outcomes in residency disputes depend heavily on the specific state, the specific facts, and the quality of the records, and some cases do not resolve favorably at all. Where the record is genuinely mixed and the taxpayer kept an abode and exceeded the day threshold, the state is often correct. Nothing about this is a guaranteed result, and the interest and any penalties on a corrected filing are real costs that a clean move would have avoided entirely.
The durable value was not the settlement. It was that the following year had a defensible filing position with a contemporaneous record behind it, which converts an annual source of anxiety into a routine return.
Why Specialized Help Mattered
Multi-state residency work is documentation discipline more than clever planning. The person who needs it least is the person who set it up correctly on day one, and almost nobody does, because on day one it looks like a moving question rather than a tax question.
Solopreneur Tax is a Coeur d'Alene, Idaho firm founded in 2021, working with small business owners, solopreneurs, and digital nomads. That last client type is the relevant one. A practice that sees location-flexible solo businesses regularly has handled the day-count reconstruction and the part-year allocation before, rather than researching it from scratch on your return.
Solopreneur Tax has 10 verified client reviews on Sam's List as of 2026-06-26. Reviews reflect the experiences of individual clients, do not represent an endorsement by Sam's List, and are not indicative of future results.
One limitation worth naming: a residency dispute that has escalated to an audit or an appeal may call for a tax attorney rather than, or in addition to, an accountant. Confirm scope, licensing, and fit before engaging, and be explicit about whether you need a return prepared or a position defended. You can compare firms by specialty and verified reviews in the Sam's List accountant directory.
Frequently Asked Questions
What is the difference between domicile and statutory residency? Domicile is your permanent legal home, determined by a facts-and-circumstances review of where your home, family, licenses, registrations, professional relationships, and belongings are. Statutory residency is a separate mechanical test many states apply, commonly requiring a permanent place of abode in the state plus presence beyond a day threshold, frequently 183 days. You can fail the second test while winning the first.
If I move mid-year, which state do I file in? Typically both, as a part-year resident in each, with income allocated to the period you were a resident of each state. Income sourced to a state where you are not a resident may also require a nonresident return. Specific rules and forms vary by state, and a few states handle part-year residency differently.
Do days spent visiting family in my old state count against me? Often yes. Statutory residency day counts generally do not care why you were present, and many states treat any part of a day spent in the state as a full day. Frequent visits combined with a retained apartment are the fact pattern most likely to trigger a residency assertion.
What records should I keep to prove I changed states? A contemporaneous day-by-day location log supported by calendar entries, card transactions, and travel confirmations, plus documentation that the facts actually changed: driver's license, voter registration, lease or deed, banking, and medical and professional relationships in the new state. Records created as events happen carry far more weight than a reconstruction made after a notice arrives.
