Overview
Moving during the tax year affects more than your address — it can change which states can tax your income, whether you must file multiple state returns, and the tax treatment of moving reimbursements. In my 15+ years advising clients, I regularly see avoidable mistakes when people assume their tax picture stays the same after a mid‑year relocation.
This guide explains the practical tax consequences of moving mid‑year, how residency tests work, how to handle state filings and credits, the limited federal moving expense rules that remain, and a checklist of records and steps to protect yourself.
Key concepts and why they matter
- Domicile vs. statutory residency: Your legal home (domicile) and how long you spend in a state (statutory residency) can both determine tax obligations.
- Part‑year resident returns: If you establish or abandon residency mid‑year, you often file part‑year returns in both states where you lived.
- Credits and allocation: Many states offer a credit for taxes paid to another state on the same income; correct allocation matters to avoid double taxation.
- Moving expense deductibility: At the federal level, moving expense deductions are suspended for most taxpayers through tax year 2025; active‑duty military moving under orders remain eligible (see IRS Publication 521 and Form 3903).
Sources: IRS Publication 521 and Form 3903 (moving expenses for military) and state Department of Revenue guidance (see IRS.gov and state sites for current rules).
How residency and filing requirements typically work
Every state sets its own tests for residency. Two common elements:
-
Domicile (your permanent place of abode): Even after a move, you may retain a domicile for some time. Courts and tax agencies look for intent—where you plan to return, where you keep important ties (home, family, voter registration, driver’s license).
-
Statutory residency (days‑based tests): Several states count days spent in the state (for example, 183 days) and may tax you as a resident if you exceed that threshold and maintain a permanent place to live there.
If you moved mid‑year you will often file:
- A part‑year resident return in the state you left for the portion of the year you lived there.
- A part‑year resident return in the state you moved to for the portion you lived there.
Some taxpayers are treated as nonresidents in one state but still owe tax on income earned or sourced there (for example, wages earned while physically working there). When income is sourced to more than one state, you may owe tax to multiple states and then claim credits to avoid double taxation.
See our primer on state residency rules for deeper examples and how states differ: State Residency Rules: How Moving Impacts Your Tax Liability (https://finhelp.io/glossary/state-residency-rules-how-moving-impacts-your-tax-liability/).
Common filing scenarios and how to handle them
-
Moved from a high‑tax state to a no‑income‑tax state (e.g., California to Texas): You’ll normally file a part‑year resident return in the state you left reporting income earned there while a resident, and then a part‑year or nonresident return if you earned state‑source income after moving. You may need to demonstrate the date your residency changed.
-
Moved into a state that taxes pensions or retirement differently: Determine which income the new state taxes and whether your former state taxes retirement income. Pensions can be sourced differently and may be taxed by one or both states without careful allocation.
-
Worked in both states during the year: Report wages to each state for the period worked there; claim any credit on your resident return for taxes paid to the nonresident state.

Federal moving expense rules (what’s changed and who qualifies)
The Tax Cuts and Jobs Act suspended the federal moving expense deduction for most taxpayers for tax years 2018 through 2025. Exceptions:
-
Active‑duty members of the U.S. Armed Forces who move because of a military order and permanent change of station can still deduct moving expenses and report them on Form 3903. See IRS Publication 521 and Form 3903.
-
Employer‑paid moving reimbursements for nonmilitary employees are generally taxable and reported as wages on Form W‑2 unless excluded under a specific employer plan or state rule.
Some states still allow a moving expense deduction or exclusion on their state return even though the federal deduction is disallowed. Check your state’s rules before assuming no deduction is available.

Practical recordkeeping and steps to protect yourself
- Date‑stamped proof of move: lease/mortgage start date, closing statement, utility setup, or work start date in the new location.
- Employment records: offer letters, paystubs showing work location and dates, employer relocation reimbursements, and any written relocation agreement.
- Government IDs and registrations: copy of new driver’s license, voter registration, vehicle registration, and Form 8822 filed with the IRS to update your address if desired (see IRS.gov).
- Moving receipts and invoices: even if you can’t deduct them federally, they matter for employer reimbursements or for state tax purposes where allowed.
- Travel and mileage logs: if using vehicle travel for a move that qualifies for a state deduction, keep clear mileage records.
In my practice I emphasize creating a single “move folder” (digital and physical) immediately when a move happens. This saves time during tax preparation and helps if a state audit questions your residency dates.
Employer reimbursements and tax withholding
- Employer payments for moving are typically taxable wages unless structured as a qualified moving expense reimbursement (rare under current federal rules). That means they may be subject to income and payroll taxes on your W‑2.
- Negotiate relocation packages with tax implications in mind: sometimes an employer can provide a gross‑up to cover additional tax withholding, but this is a negotiation point.
Dealing with multi‑state credits and avoiding double taxation
Most states offer a credit to residents for taxes paid to another state on the same income. To claim such credits you must:
- Properly allocate income to each state.
- Attach supporting nonresident or part‑year returns showing the tax paid to the other state.
Keep in mind that credit rules and formulas vary substantially between states. If you expect significant liability in both states, talking to a CPA or state tax professional can reduce errors and the risk of overpaying.
See our discussion of managing state credits: Managing State Tax Credits When Moving Between States (https://finhelp.io/glossary/managing-state-tax-credits-when-moving-between-states/).
Special situations to watch for
- Students and recent graduates who move for a job may need to file returns in both their college state and new employer state.
- Remote workers: if you live in one state but work remotely for an employer in another, you could create tax obligations in both states depending on sourcing rules.
- Moving for a new job that pays sign‑on or remote bonuses: taxable treatment varies; document the reason for each payment.
Common mistakes and how to avoid them
- Waiting to update your driver’s license, voter registration, or bank accounts. These documents help establish domicile.
- Failing to file part‑year returns or claiming credits without proper nonresident tax documentation.
- Treating employer moving reimbursements as tax‑free when they are generally taxable for nonmilitary taxpayers.
Action checklist before you file
- Collect proof of the exact date you changed primary residence.
- Pull paystubs and employer documentation showing where and when income was earned.
- Review both states’ part‑year filing rules and credit provisions.
- Check whether your state allows any moving expense deduction or exclusion.
- Consider consulting a CPA if you have substantial income or complex cross‑state activity.
