Quick overview
Relocating to a different state affects more than your mailbox. State tax systems vary widely: some have no personal income tax (e.g., Florida, Texas), while others impose high top rates (e.g., California). Beyond income tax, differences in property taxes, sales taxes, retirement-income rules, capital gains treatment, and estate or inheritance taxes can shift your overall tax burden materially. In my 15+ years advising clients, a move that looked attractive on headline income-tax savings sometimes produced offsetting costs in property taxes or sales taxes. This guide walks through what to check, how residency is determined, common pitfalls, and practical steps to protect your tax position.
Sources you’ll want on-hand: the IRS for federal filing impacts and certain residency interactions (https://www.irs.gov), and the Consumer Financial Protection Bureau for moving and financial checklists (https://www.consumerfinance.gov).
Residency and filing status: why the dates matter
When you change states, the first question is: which state considers you a resident—and when? States use different tests to determine residency:
- Physical presence or “days” tests (some states use a 183-day rule; others look at where you spend most days).
- Intent and domicile factors (where you work, vote, register your car, and intend to make your permanent home).
- Statutory ties (driver’s license, voter registration, secondary homes, family location).
If you move mid-tax year you will often file as a part‑year resident in both states. That can create complexity: wages earned while physically present in State A may be taxable there, while wages after the move are taxed by State B. Also, some states tax nonresidents on income sourced to the state (for example, income from work performed there or rental income from property located there).
Practical action: document the move date carefully (closing statements, a signed lease, utility start dates, driver’s license change, and travel logs). These records are key if a state later questions your residency claim.

Income tax: beyond the headline rate
Compare more than the top marginal rate. Consider:
- Progressive vs flat rates and how your income mix (salary, bonuses, capital gains, dividends) is taxed. Some states tax social security and pension income differently or exempt certain retirement income.
- Withholding and estimated payments. If you change states midyear, update your employer withholding and review estimated tax obligations to both states.
- Tax credits you may lose or gain (child tax credits, earned income credits, or state-specific credits tied to residency).
Example from practice: a client leaving California for Texas saved on state income tax, but increased sales-tax and property-tax exposure—so we modeled net after-tax cash flow over five years to verify the move’s benefit.
Capital gains, retirement income, and estate taxes
- Capital gains: Some states tax capital gains as ordinary income; a few have no capital gains tax. If you plan to sell stock or a business, the state where you are domiciled at sale can affect the tax due.
- Retirement income: States differ on treatment of pensions, 401(k) distributions, IRAs, and Social Security benefits. Some states exempt retirement income partially or fully; others tax it.
- Estate and inheritance taxes: A move can shift exposure to state estate/inheritance taxes. Check the decedent’s probate domicile rules and whether your assets (real estate in another state) create local tax rules.
Property, sales, and local taxes
Property tax levels and assessment methods vary dramatically. A lower property-tax rate can be offset by a higher assessed value or vice versa. Sales tax also varies and includes local add-ons in many states.
Checklist for property and local taxes:
- Review average effective property-tax rates and typical home values in your target county.
- Research local sales-tax combined rates and major exemptions.
- Ask about vehicle registration and personal property taxes.
Business owners and nexus issues
If you own a business, moving can change your business’s state tax nexus and registration requirements. Remote work, employees in multiple states, or owning inventory in a state can create sales tax or corporate income tax obligations.
Action: speak with your CPA or state tax counsel before changing business addresses or moving stock/inventory to a new state.
Withholding, estimated payments, and employer moves
If your employer moves you, confirm whether the company will adjust state withholding and whether it will reimburse state tax equalization. If you work remotely for an employer in another state, you may create withholding obligations in the employer’s state or in your state—this is an evolving area, especially for remote workers.

Practical relocation tax planning steps (timeline)
Before you move:
- Run a tax comparison analysis (state-by-state) for projected income, property, sales, retirement, and capital-gains tax. Model best- and worst-case scenarios.
- Check residency rules for the destination state and start establishing domicile: obtain a driver’s license, register to vote, open bank accounts, and update primary residence documentation.
- Discuss moving-related benefits with your employer. Understand whether moving reimbursements are taxable federally and how states treat those reimbursements.
During the move year:
- Track days in each state and keep receipts/records tied to move dates.
- Update employer withholding and estimated payments.
- If you sell a home, confirm state capital-gains rules and federal exclusions (see IRS rules on home sale exclusions at https://www.irs.gov/).
After you move:
- File accurate part‑year returns where required.
- Keep documentation of intent to remain in new state (lease/mortgage, utility bills, voter registration, tax returns filed as resident).
Common mistakes I see
- Focusing only on income tax and ignoring property, sales, and local taxes.
- Failing to establish clear domicile before returning to the former state for extended visits.
- Not documenting the exact move date and ties to the new state.
- Assuming employer withholding will automatically protect you from multistate exposure.
Example scenarios (short)
1) High-earner moves from a high-income-tax state to a no-income-tax state but keeps a business and rental property in the old state. Result: still owes nonresident tax on rental income and potentially business income sourced to the old state.
2) Retiree moves to a state that exempts pensions, improving after‑tax monthly income even though property taxes are slightly higher. Financial simulations should include expected retirement distributions.
FAQs (brief)
Q: Will moving out of a state erase my past tax obligations? A: No. You remain responsible for tax years in which you were a resident and for any state-sourced income earned after you leave until you file final returns.
Q: How do states verify residency changes? A: States may audit your claims using records like DMV changes, voter registration, utility bills, travel logs, and tax return history.

Professional tips (actionable)
1) Run a forward-looking cash-flow model that includes state tax, property tax, and likely changes to insurance and utilities for at least five years.
2) Keep an organized move file with contemporaneous evidence of the relocation date and intent to change domicile.
3) Get a multistate tax-savvy CPA or tax attorney involved before you finalize the move—especially if you have significant investments, business interests, or complex retirement income.
