There’s No Place Like Home: Avoid these pitfalls when changing your tax domicile.

As you set goals and develop your personal wealth story, where you live matters for many reasons, including taxes. The tax domicile and residency rules – which are imposed state-by-state and vary widely – are more important now than ever. These rules may be familiar to “snowbirds”, but also impact those with hybrid or remote working situations, and those transitioning to retirement, who may live, work, and spend significant time in multiple states. Taking control of your tax “home” can save thousands (or even millions) of dollars in combined state income and estate taxes. But it’s not as simple as a new address, and requires expert advice and advance planning.

Income Tax Implications

In addition to warm weather, it is no secret why many folks retire to Florida: no state income tax. Florida may not be part of your retirement goal, but state income taxes can have a huge impact on the success of your financial plan.

Seven states have no state income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, and Wyoming. Residents in New Hampshire pay tax only on dividends and interest earnings, while residents in Washington state only have their capital gains income taxed if they are in a high enough bracket.i

In contrast, the new 2023 Massachusetts Millionaire’s Tax—which taxes an additional 4% on income over $1 million—has motivated some to flee the state (including Boston Celtics forward Grant Williams, who recently turned down a Celtics offer and moved to the Dallas Mavericks in part because of the new surtax).

Estate Tax Implications

Estate tax laws differ significantly from state to state. Some states don’t have any estate, inheritance, or gift taxes; some allow a large portion of an estate to pass free of state tax; some have a very low threshold.

Eleven states (Connecticut, Hawaii, Illinois, Maine, Massachusetts, Minnesota, New York, Oregon, Rhode Island, Vermont, and Washington) and the District of Columbia impose an estate tax. Six states (Iowa, Kentucky, Nebraska, New Jersey, and Pennsylvania) impose an inheritance tax on recipients of inherited assets. Maryland imposes both.ii

Note: if you change residency for estate planning reasons, you also should review your estate plan with your attorney and wealth advisor to ensure your existing documents continue to be enforceable and comply with the laws and regulations of your new home.

The Key: Successfully Establishing Residency

To a large extent, which state’s income and estate tax laws apply depends on residency.

Most states will consider you a resident for tax purposes if you spend 183 days or more in that state. If you spend significant time in another state, or even have another residence there, you need to clearly prove your status to avoid double taxation issues.

Examples of evidence required to establish a new residency/domicile include:

  1. Record of time spent within each state (per the 183-day rule)
  2. Voting records and updated voter registration
  3. Transfer of driver’s license and vehicle registration
  4. Establishment of professional services (e.g., bank, brokerage accounts, lawyers, doctors)
  5. Change of mailing address
  6. Purchase or lease of residence and other property (e.g., car, boat)
  7. Declaration of residency in legal documents, including wills
  8. Volunteering with and supporting charities in the state
  9. Memberships in clubs and organizations in the state
  10. Movement of what is “near and dear” to you (e.g., family, pets)

It is important to remember that investing entails risk. Stock markets and investments in individual stocks are volatile and can decline significantly in response to issuer, market, economic, political, regulatory, geopolitical, and other conditions. Investments in foreign markets through issuers or currencies can involve greater risk and volatility than U.S. investments because of adverse market, economic, political, regulatory, geopolitical, or other conditions. Emerging markets can have less market structure, depth, and regulatory oversight and greater political, social, and economic instability than developed markets. Fixed Income investments, including floating rate bonds, involve risks such as interest rate risk, credit risk and market risk, including the possible loss of principal. Interest rate risk is the risk that interest rates will rise, causing bond prices to fall. The value of a portfolio will fluctuate based on market conditions and the value of the underlying securities. Diversification does not assure or guarantee better performance and cannot eliminate the risk of investment loss. Investors should contact a tax advisor regarding the suitability of tax-exempt investments in their portfolio.
