Overview

Moving for remote work often changes your state tax picture. Some states tax you based on domicile (your permanent home), others use a statutory or “183‑day” test, and many combine factors. Misunderstanding these rules can lead to double filing, audits, or unexpected tax assessments. (See IRS guidance on residency and state tax rules: https://www.irs.gov/.)

Key residency tests remote workers should know

  • Domicile: Your primary, permanent home. Changing domicile requires clear actions (sell or rent out your old home, get a local driver’s license, register to vote).
  • Statutory (183‑day) tests: Several states treat you as a resident if you spend 183 or more days there in a year, but how days are counted varies by state.
  • Intent and ties: States weigh where you keep family, vehicles, bank accounts, professional licenses, and where you spend holidays.

How and when you may owe taxes in two states

  • Part‑year resident rules: If you move mid‑year, you’ll generally file as a part‑year resident in both states and allocate income earned while a resident of each state.
  • Statutory residency: States such as New York or California may treat you as resident if you maintain a permanent place and spend substantial time there; they tax your worldwide income as a resident would (see New York Department of Taxation & Finance: https://www.tax.ny.gov/ and California FTB: https://www.ftb.ca.gov/).
  • Sourcing wages: Some states tax income earned for work performed within the state even if your employer is elsewhere.

Practical steps to establish (or abandon) residency

  1. Update core documents quickly: get a local driver’s license, register to vote, and change your address on tax and financial accounts.
  2. Sever ties to the former state: sell or rent previous home, close or move local accounts, and update memberships. In my practice, clients who complete a sequence of actions (license → voter registration → local banking) shorten the time auditors question the change.
  3. Track days and work location: keep a calendar, travel receipts, and screenshots of remote work location when traveling.
  4. Adjust withholding and estimated taxes: tell payroll the correct state on Form W‑4 state equivalents or request employer withholding changes.

Documentation checklist (keep for 4–7 years)

  • Travel log showing days in each state.
  • Lease or deed, utility bills, and home‑insurance policy showing your primary address.
  • Driver’s license, voter registration, and vehicle registration.
  • Employer statements confirming primary work location and any state withholding changes.

Employer obligations and nexus concerns

Employers may need to withhold in the employee’s work state or register for payroll tax there. Remote‑worker nexus rules increasingly require employer action; discuss withholding changes with HR or payroll early to avoid underwithholding and penalties.

Common mistakes and misconceptions

  • Assuming a single action (like changing an address) instantly changes residency — most states look for multiple supporting facts.
  • Believing a no‑income‑tax state removes all exposure — previous state domicile or statutory residency can still trigger tax obligations.
  • Not updating employer withholding — that generates underpayment penalties.

When to consult a professional

If you have high income, dual residences, or received a notice from a state tax agency, consult a tax pro. Multistate returns, credits for taxes paid to another state, and audit defense require state‑specific expertise. (Authoritative IRS guidance and many state tax agency pages discuss part‑year and nonresident filing rules: https://www.irs.gov/.)

Quick action plan for movers (first 60 days)

  1. Decide intended domicile and document it. 2. Change license/voter registration/vehicle registration. 3. Notify employer and update withholding. 4. Start a day‑by‑day travel log. 5. Consult a tax advisor if you have complex ties.
