How can state residency planning reduce your income tax burden?
State residency planning helps you reduce state income taxes by moving your legal domicile and factual ties to a state with lower or no personal income tax, then documenting that change so it withstands review by tax authorities. Done correctly, it can eliminate or significantly reduce state-level income taxes on wages, retirement income, investment income, and business profits. Done poorly, it exposes you to audits, back taxes, penalties, and interest.
Below is a practical, compliance-first guide to what matters, what to document, and professional tips that I use in practice when advising clients.
Why residency planning matters now
Seven U.S. states currently do not levy a broad-based individual income tax: Alaska, Florida, Nevada, South Dakota, Texas, Washington, and Wyoming. Relocating to one of these states — or another low-tax jurisdiction — can materially change after-tax cash flow for high earners, retirees, and business owners. But states are increasingly aggressive in enforcing residency rules because moving residents are a meaningful revenue source, so documentation and timing are critical (see guidance from the Consumer Financial Protection Bureau on state taxes) (https://www.consumerfinance.gov/).
The federal government does not set state residency rules; each state defines its own tests (domicile, statutory residency, and days-present rules). For federal residency topics you can consult IRS guidance, but for state residency you must review the new state’s statutes and administrative rules and prepare evidence accordingly (IRS on residency and residence-related guidance: https://www.irs.gov).
Domicile vs. residency vs. statutory residency (plain language)
- Domicile: Your permanent home — the state you intend to return to even if you live elsewhere temporarily. It’s determined by intent plus objective facts (home, family, where you vote).
- Factual residency: How many days you spend in a state and your daily life there. Some states use a day-count test (often 183 days) to determine statutory residency.
- Statutory residency: When a state taxes you because you meet specific rules (for example, spending more than a threshold number of days there while maintaining a permanent place).
Understanding these three concepts is essential because states use a mix of them when deciding whether to tax you.
Practical steps to establish and document residency (checklist I use for clients)
- Set a clear domicile date and communicate it to advisors.
- Get a state driver’s license and vehicle registration in the new state immediately after your move.
- Register to vote and update voter records.
- Change your mailing address everywhere that matters: banks, investment accounts, retirement plan administrators, credit cards, medical providers, and tax preparers.
- Open and use local bank accounts and a local primary-care physician; join local community organizations and churches if applicable.
- Transfer professional licenses and local memberships (bar, CPA, medical licensing boards) when required.
- Buy or lease a residence — the more substantial the ownership or lease, the stronger the tie. If you keep a home in the old state, keep it only for an allowed temporary purpose and document the reason.
- File a part‑year resident return for the year you move and, if owed, a nonresident return in the former state for income sourced to that state.
- Keep a contemporaneous travel log for at least three years showing days in each state — this is often decisive in audits.
Document retention: keep receipts, closing statements, DMV changes, voter registration, employment records, and logs for at least three to six years.
Tax-year and filing considerations
- Part-year returns: When you move mid-year, you typically file part-year resident returns in both states. Each state allocates income earned while you were a resident, and many offer credits for taxes paid to another state on the same income.
- Source-based income: States tax income sourced to them — for example, wages for work performed there, rental income from property located there, and business income from activities in that state.
- Retirement income: Some states tax pensions, IRA distributions, and investment income differently. Social Security benefits are exempt from federal tax for many, but a few states also tax Social Security — check your target state’s rules.
- Business nexus: Moving your personal residency doesn’t automatically move your business tax obligations. If your business has physical presence or earns income in the former state, you may still owe state business taxes.

Common audit triggers and how to reduce risk
- Maintaining many strong ties (family, primary bank, vehicle, voter registration) in the former state while claiming domicile elsewhere is a frequent red flag.
- Sudden, inconsistent records (e.g., your driver’s license shows one state but your bills and voting record show another) invite scrutiny.
- High-net-worth taxpayers, retirees with significant investment income, and those who keep expensive second homes attract closer review.
Mitigation: create a consistent paper trail dated around your move. In my practice I recommend consolidating communications and changing critical documents within 30–60 days of the declared domicile date.
Timing and strategic moves
- Year-end moves: Moving near the start or end of a calendar year simplifies allocation of income and reduces part-year complexity.
- Retirement timing: For retirees, moving before required minimum distributions (RMDs) or before receiving large lump-sum payouts can preserve more after-tax income.
However, don’t move solely for taxes without considering property tax, sales tax, insurance, healthcare access, estate tax rules, and quality-of-life factors.
Example scenarios (anonymized)
-
Retiree case: A client moved domicile from California to Florida before retirement. They established clear ties by selling their CA home, changing their driver’s license and voter registration, and moving most assets to local advisors. The result: no Florida state income tax on retirement distributions and investment income (while still filing a final part‑year CA return for income earned in CA). Documented steps and timing were crucial to avoid CA’s statutory residency challenge.
-
Small business owner: A client relocated their family and residence to a no-income-tax state but maintained a remote business with customers in the prior state. We reviewed nexus rules and payroll withholding to avoid unexpected state withholding liabilities while capturing personal income-tax savings.

Pitfalls and misconceptions
- ‘‘I’ll just claim my new state on my driver’s license’’: A single document rarely suffices. States look at your whole life pattern.
- ‘‘No income tax means I’ll always save money’’: Higher property taxes, sales tax, insurance costs, and changes in retirement tax treatment can offset income-tax benefits.
- ‘‘I can keep a house in the old state without consequence’’: Maintaining a year-round residence in the old state can create statutory residency exposure.
When to get professional help
Hire a tax attorney or CPA experienced in state residency issues when:
- You’re a high-net-worth individual or expect large taxable events during the move.
- You maintain complex business operations across states.
- You own multiple residences and need a formal domicile plan.
In my experience, an upfront investment in professional planning and a well-documented move typically costs far less than the tax, penalties, and legal fees that follow from a contested residency audit.
Bottom line
State residency planning is a powerful but technical tool to reduce your state income tax burden. Success requires a clear domicile decision, consistent and contemporaneous evidence, correct handling of part‑year and source income, and attention to business nexus rules. Use the checklists above, consult professionals, and keep detailed records to protect your tax position.
