Should You Move to Another State to Reduce Your Income and Estate Taxes?
Changes in state tax policy can prompt people to reconsider where they want to live. This is particularly true for individuals approaching retirement, business owners anticipating a major financial transaction, and families with substantial accumulated wealth.
If you live in a state with high income taxes, an estate tax, or the possibility of future tax increases, relocating to a lower-tax state may offer meaningful financial benefits.
For some households, the potential savings could amount to millions of dollars over time. For others, the benefits may be smaller once housing expenses, property taxes, insurance, and other costs are considered.
There is also an important complication: moving to another state does not automatically mean your former state will stop treating you as a resident.
Understanding the rules governing domicile and residency is essential before making a decision.
Which States Have No Individual Income Tax?
Eight states currently impose no broad individual income tax:
Alaska
Florida
Nevada
New Hampshire
South Dakota
Tennessee
Texas
Wyoming
Washington has historically been included among states without a broad individual income tax. However, Washington already taxes certain long-term capital gains, and legislation enacted in 2026 establishes a new 9.9% income tax on Washington taxable income exceeding $1 million, beginning January 1, 2028.
For higher-income households, the difference between state tax systems can be substantial.
Consider a married couple with $2 million of income potentially subject to Washington's new tax before the standard deduction. Assuming the full $1 million deduction applies and no other adjustments or credits affect the calculation, the potential tax liability could approach $99,000.
That is a meaningful amount, particularly if the income results from a one-time financial event.
Someone expecting a substantial business sale, large investment gains, or another major transaction may have particular reason to evaluate the benefits of relocating.
However, the tax treatment depends on the character and source of the income, as well as the timing of the transaction.
The Washington Department of Revenue's income tax guidance provides information about the new tax and its implementation.
Retirement Income and Roth Conversions
The potential benefits of relocating are not limited to business owners and high-income earners.
Retirement income may come from traditional IRAs, 401(k)s, pensions, Social Security, and taxable investment accounts. States differ in how they tax these sources.
Relocating to a state without an individual income tax could reduce the state tax liability associated with retirement account withdrawals and certain other income.
It may also create opportunities for Roth conversions.
Converting money from a traditional IRA to a Roth IRA generally creates taxable income in the year of conversion. Completing a conversion after legitimately establishing residency in a state without an individual income tax could potentially reduce the overall tax cost.
However, federal income taxes still apply, and the timing and size of a conversion should be evaluated within a broader financial plan.
For more on this strategy, see our article, Should You Convert Your Traditional IRA to a Roth?.
State Estate Taxes May Be an Even Bigger Consideration
Income taxes are only part of the equation.
For families with substantial wealth, state estate taxes can create significant liabilities even when the estate falls well below the federal estate tax exemption.
For 2026, the federal estate and gift tax basic exclusion amount is $15 million per person, before accounting for prior use of the exemption.
Several states impose their own estate taxes with substantially lower exemption amounts.
This means a family could have no federal estate tax liability but still owe hundreds of thousands of dollars, or potentially more, in state estate taxes.
A Washington Estate Tax Example
Washington provides a useful illustration.
For deaths occurring on or after July 1, 2026, Washington's estate tax exclusion is $3 million, with graduated rates ranging from 10% to 20%.
Consider an unmarried Washington resident with a $10 million estate.
Assuming the entire estate is subject to Washington estate tax and there are no additional deductions or adjustments, the Washington taxable estate would be approximately $7 million after the exclusion.
Under the state's applicable estate tax schedule, the resulting state estate tax could exceed $1 million.
That is a substantial potential liability for an estate that may owe no federal estate tax.
For married couples, estate planning becomes particularly important because Washington does not automatically permit the unused state estate tax exclusion of the first spouse to die to transfer to the surviving spouse.
Appropriate trust planning may help preserve the benefit of both spouses' exclusions, depending on the circumstances.
The Washington Department of Revenue's estate tax tables provide the applicable exclusions and rates.
Moving to a state without an estate tax could potentially reduce this exposure. However, the outcome depends on establishing a new domicile and whether any property remains taxable in the former state.
What Does It Take to Stop Being a Resident of a High-Tax State?
This is where relocation planning becomes more complicated.
States generally use two concepts to determine whether an individual is subject to resident income taxation: domicile and statutory residency.
Domicile generally refers to the place you consider your permanent home and intend to return to when you are away.
You can own homes in multiple states, but you generally have only one domicile at a time.
To change domicile, you typically need to demonstrate that you have abandoned your former domicile and established a new permanent home elsewhere.
Statutory residency is different. Some states can treat you as a resident for income tax purposes even when you are domiciled elsewhere, usually because you maintain a qualifying residence and spend a specified number of days in the state.
A successful move therefore requires addressing two separate questions:
Have you genuinely established a new domicile?
Could your former state still classify you as a statutory resident?
The answer depends on the laws of the states involved.
The 183-Day Rule Is Not a Universal Safe Harbor
One of the most common misconceptions is that spending 183 days in a new state automatically makes you a resident there and a nonresident everywhere else.
That is not how the rules work.
Different states apply different residency tests.
New York
New York generally considers an individual a resident if they are domiciled in the state.
Even someone domiciled elsewhere may be treated as a New York resident if they maintain a permanent place of abode in New York for substantially all of the taxable year and spend 184 or more days there.
Any part of a day generally counts toward the day total, subject to limited exceptions.
New York also generally requires clear and convincing evidence that a former resident has abandoned their New York domicile and established a new one.
The New York Department of Taxation and Finance's residency definitions explain these rules.
California
California takes a different approach.
Residency generally depends on whether someone is domiciled in California and whether their absence from the state is temporary or transitory, or whether they are present in California for a purpose that is not temporary or transitory.
California examines a broad range of personal, financial, and professional connections.
There is no universal 183-day safe harbor that automatically terminates California residency.
Someone who spends fewer than 183 days in California could still be considered a resident if their circumstances indicate that California remains the center of their life.
The California Franchise Tax Board's residency guidance explains how the state distinguishes residents, nonresidents, and part-year residents.
Washington
Washington's residency rules for its capital gains tax generally include individuals domiciled in Washington.
They can also include certain individuals who maintain a place of abode in Washington and spend more than 183 days in the state during the taxable year.
Washington also provides a limited exception for certain individuals domiciled in the state who maintain no permanent abode in Washington, maintain an abode outside Washington throughout the year, and spend no more than 30 days in Washington.
The state's newly enacted high-income tax has its own statutory provisions addressing residency.
The Washington Administrative Code, WAC 458-20-301, explains the capital gains tax residency and domicile rules.
These examples illustrate why a person contemplating relocation should not rely on a generic day-count rule.
What Do States Actually Examine When Determining Domicile?
When a former state questions whether someone has genuinely relocated, tax authorities may review a broad range of evidence.
No single factor necessarily determines the outcome. Instead, states often evaluate the overall pattern of your activities and connections.
1. Your Homes and Living Arrangements
Tax authorities may examine where you own or rent homes, how those properties are used, and which residence appears to be your primary home.
They may consider:
Whether you sold your former residence or continue to own it.
Whether the former home remains furnished and available for personal use.
Whether your new residence is suitable for year-round living.
Where your furniture, artwork, valuables, and other important belongings are located.
Which residence you return to after traveling.
Whether you claim a homestead or principal-residence property tax exemption.
For example, someone who claims to have moved from California to Nevada but retains a large California home, keeps most personal belongings there, and spends considerable time at that property may face questions about whether the move was permanent.
Selling your former home can provide strong evidence of a change in domicile, but it is not always necessary.
The important consideration is whether your overall living arrangements support your stated intention.
2. Where Your Spouse and Family Live
Family connections can carry considerable weight.
Tax authorities may examine where your spouse resides, where dependent children attend school, and where your family spends most of its time.
If you establish a residence in Florida while your spouse continues living in New York and your children remain enrolled in New York schools, those circumstances may complicate your claim that you have permanently relocated.
Spouses can have different domiciles in some circumstances, but those situations require careful analysis.
For married couples contemplating relocation, it is generally important to evaluate the household's circumstances rather than focusing exclusively on one spouse's activities.
3. Where You Spend Your Time
Tax authorities may compare the number of days spent in your former state, your new state, and other locations.
But they may also examine the pattern of your visits.
For example:
Do you return to your former state for extended periods?
Do you spend holidays and important family occasions there?
Where do you typically spend the majority of your time?
Is your presence in the new state consistent throughout the year?
Are you traveling frequently without establishing a meaningful connection to the new location?
Maintaining a contemporaneous travel calendar is particularly important when you own homes in multiple states.
Supporting records may include airline itineraries, hotel receipts, toll records, credit card transactions, and other documentation showing where you were on particular dates.
If a state challenges your residency, records created at the time are generally more useful than attempting to reconstruct several years of travel from memory.
4. Your Employment and Business Activities
The location of your work and business activities may also influence domicile.
Tax authorities may examine:
Where you physically perform your work.
Whether you continue to maintain an office in the former state.
Where your business is managed.
Whether you hold professional licenses in the former state.
Whether your employment arrangement is temporary or permanent.
Where you regularly meet clients, customers, or colleagues.
For example, someone who moves to Wyoming but continues operating a business from an office in California may face both residency questions and potential California-source income tax obligations.
A person can legitimately establish domicile elsewhere while continuing to own a business in the former state.
However, the business ownership, income sourcing, and residency issues must be evaluated separately.
5. Your Driver's License, Vehicle Registration, and Voter Registration
These records are commonly examined because they indicate where you have represented yourself as a resident.
After a permanent move, it is generally appropriate to update:
Your driver's license.
Vehicle registrations.
Voter registration.
State identification documents.
Applicable professional licenses.
The timing of these changes can matter.
For example, claiming that you permanently moved to Florida in January while continuing to maintain a California driver's license and voter registration through December may create inconsistent evidence.
However, obtaining a new driver's license does not, by itself, establish a new domicile.
States look at whether your actions collectively support your stated intention.
6. Your Financial and Tax Records
Tax authorities may review how you identify your residence on financial and legal documents.
Relevant records may include:
Federal income tax returns.
State resident and nonresident tax returns.
Bank and brokerage account addresses.
Credit card and insurance records.
Retirement account and employer records.
Trust documents and estate planning records.
Business registrations.
Property tax filings.
A consistent address across these records can help substantiate a change in domicile.
Inconsistent information may raise questions.
For example, someone claiming Nevada residency while continuing to report a California address on tax returns, investment accounts, and important legal documents may have difficulty demonstrating that the move was permanent.
7. Healthcare, Social, and Community Connections
Some states also examine the location of your personal and community relationships.
These can include:
Physicians, dentists, and other healthcare providers.
Accountants and attorneys.
Social and country club memberships.
Religious organizations.
Professional associations.
Volunteer and charitable activities.
Recreational memberships and other community involvement.
California's residency guidance explains how personal and financial connections can influence a residency determination.
Maintaining relationships in your former state does not automatically prevent you from changing domicile.
However, if nearly every important aspect of your personal life remains centered there, those connections may weaken your position.
8. Your Intentions and Whether Your Actions Support Them
Ultimately, domicile involves an intention to make a particular location your permanent home.
But tax authorities generally place more weight on objective evidence than on statements of intent alone.
For example, signing a declaration that you intend to live permanently in Florida may help document your decision.
However, that declaration may carry limited weight if you continue spending most of your time in your former state and maintain your principal household there.
The strongest evidence of a legitimate relocation is a consistent pattern of conduct showing that your new state has become the center of your life.
A Practical Example: Moving From Washington to Nevada
Consider a married couple approaching retirement who owns a home in Washington and decides to relocate to Nevada.
They want to reduce potential exposure to Washington's new income tax and state estate tax.
To support a genuine change of domicile, they might:
Purchase or lease a Nevada residence suitable for permanent occupancy.
Physically move their household and important personal belongings.
Sell their Washington residence or clearly establish its role as a secondary property.
Obtain Nevada driver's licenses and register their vehicles there.
Update voter registrations and financial account addresses.
File appropriate part-year or nonresident tax returns where required.
Establish healthcare providers and other meaningful connections in Nevada.
Maintain detailed records of their time in both states.
Review their estate planning documents under Nevada law.
Coordinate the timing of the move with any anticipated business sale, investment gain, or other significant financial event.
These steps would help establish the facts supporting their relocation.
However, no checklist guarantees a particular residency determination.
For Washington income tax purposes, the couple would also need to consider the applicable domicile and statutory residency rules.
For Washington estate tax purposes, they would need to establish that Nevada, rather than Washington, had become their domicile.
If they retain Washington real estate or other property subject to Washington estate tax, some Washington estate tax exposure could remain.
The Washington Department of Revenue's estate tax guidance explains how the tax can apply to residents and nonresidents who own property in Washington.
When Does the Change in Residency Become Effective?
The effective date of a move can have important financial consequences.
A person who permanently relocates during the year may be treated as a part-year resident of the former state.
That can mean the former state taxes income received while the individual was still a resident, while the new state applies its own rules to income received after the move.
However, the timing of income recognition, source of income, and specific state rules can complicate the analysis.
For example, moving shortly before receiving proceeds from a business sale does not necessarily mean the gain escapes taxation in the former state.
If the transaction was substantially completed before the move, or the income remains sourced to the former state, taxes may still apply.
The same caution applies to deferred compensation, stock options, and other transactions with complex timing or sourcing rules.
Anyone contemplating a move ahead of a major financial event should obtain tax advice before the transaction occurs.
Income Tax Residency and Estate Tax Domicile Are Different Questions
Even after you successfully change your income tax residency, estate tax considerations may remain.
State estate taxes often depend on where you are domiciled at death.
The location of particular assets can also matter.
For example, a former Washington resident who establishes domicile in Nevada may still have Washington estate tax exposure related to certain real estate or tangible personal property retained in Washington.
Other states have their own rules governing property owned by nonresidents.
For families with substantial wealth, the estate tax analysis should be completed separately from the annual income tax analysis.
It is also important to review existing wills, trusts, powers of attorney, and other estate planning documents after relocating.
Consider the Total Cost of Relocating
A lower-tax state is not necessarily a lower-cost state.
Property taxes, homeowners insurance, housing expenses, sales taxes, and healthcare costs can offset some of the savings.
There are also costs associated with selling a home, purchasing another residence, and relocating a household. For someone planning to maintain two homes, the ongoing expenses may further reduce the financial benefit.
Before committing to a permanent move, consider spending an extended period in your prospective new location. A place that feels ideal during a vacation may be quite different when you experience its everyday routines, healthcare options, and living expenses.
In our article, Before You Move in Retirement, Take It for a Test Drive, we explore how spending time living like a local can help you evaluate whether a destination is truly the right fit.
Healthcare deserves particular attention.
If you are enrolled in Medicare Advantage, moving to another state may require selecting a new plan because coverage options and provider networks vary by location. Even with Original Medicare, you should consider access to physicians, specialists, and hospitals in your new community.
Our article, Navigating Medicare: What Retirees Need to Know for Their Financial Plans, explains how healthcare decisions fit into retirement planning.
The broader financial analysis should also consider how relocating affects your retirement income strategy, investment withdrawals, and long-term spending needs.
As we discuss in Retirement Planning Beyond the 4% Rule, retirement income planning involves much more than applying a fixed withdrawal percentage. Taxes, spending patterns, investment returns, and changing circumstances all matter.
A relocation decision should be evaluated within that same comprehensive framework.
The Emotional and Family Considerations of Relocating
While the potential tax savings from relocating can be substantial, the decision involves much more than money.
Moving may mean leaving behind family, longtime friends, familiar routines, and a community you have spent years building. It can also create opportunities to be closer to loved ones, enjoy a different lifestyle, or pursue experiences that matter to you.
Before making a decision, consider not only how much you might save in taxes, but also how the move would affect your relationships, sense of belonging, and overall quality of life.
We explore this perspective further in The Most Important Retirement Asset Isn't Your Money. It's Your Time..
After all, the purpose of financial planning is not simply to preserve more wealth, but to use that wealth to live a meaningful and fulfilling life.
Before Relocating, Build a Coordinated Plan
Moving to another state can produce meaningful income and estate tax savings, particularly for households with substantial wealth or anticipated taxable income.
But realizing those benefits requires more than selecting a lower-tax destination.
Before making a move, work with your financial advisor, CPA, and estate planning attorney to evaluate the potential savings, the residency rules of both states, the treatment of your income and assets, and the personal implications of relocating.
A coordinated plan can help you understand whether the potential financial benefits justify the costs and disruption.
If you are considering moving to another state because of income taxes, estate taxes, or changes in tax policy, we invite you to schedule a complimentary 15-minute call to discuss how the decision may fit into your broader financial plan.
Frequently Asked Questions
How many days do I need to live in another state to stop being a resident of my former state?
There is no universal number of days. Residency depends on the laws of the states involved, including domicile and any statutory residency tests. Spending more than 183 days in a new state does not automatically terminate residency in your former state.
Do I need to sell my home in my former state?
Not necessarily. You can own homes in multiple states. However, retaining a substantial residence in your former state may be relevant when tax authorities evaluate whether you genuinely established a new domicile.
Can my former state challenge my residency after I move?
Yes. States may review tax returns, property ownership, travel records, family connections, financial documents, and other evidence to determine whether a change in residency was legitimate. Keeping thorough records can be important.
Can I still owe income taxes to my former state after becoming a nonresident?
Yes. Certain income sourced to your former state, such as rental income, business income, or compensation for work performed there, may remain taxable even after you establish domicile elsewhere.
Does changing my residency eliminate state estate taxes?
Not necessarily. A legitimate change of domicile may reduce estate tax exposure, but real estate and certain other property retained in the former state may remain taxable there. Estate tax domicile and income tax residency should be evaluated separately.
