Where you live and what it costs in tax

Relocation in retirement is frequently justified on tax grounds. The tax differences are real and they are one component of a total cost that sometimes points the other way.

The variation

Several states levy no personal income tax at all.

A majority of states do not tax Social Security benefits, and the number has grown as several states have changed their treatment recently.

Treatment of other retirement income varies widely. Some states exempt public pensions but not private ones. Some provide an exclusion up to a defined amount. Some tax retirement income in full.

The practical implication is that two retirees with identical income can face materially different state tax bills depending on where they live.

The other taxes

Which frequently offset the headline difference.

Property taxes vary enormously and are a major ongoing cost for homeowners.

States without income tax frequently have higher property taxes, since the revenue has to come from somewhere.

Many states offer exemptions or assessment limits for older residents, which are worth investigating specifically.

Sales taxes, including whether groceries and prescriptions are exempt.

Estate and inheritance taxes at state level, which exist in a minority of states, sometimes with thresholds well below the federal one.

This is worth checking for anyone with a substantial estate, since it can affect a much broader group than the federal tax does.

Vehicle and other local taxes, which vary and add up.

The costs that are not taxes

Frequently larger than the tax difference.

Property insurance, which has risen dramatically in some regions and can exceed the income tax saving on its own.

Health insurance costs and provider availability, which vary by market.

Utility costs, particularly cooling and heating in extreme climates.

Housing costs themselves, which is generally the largest factor.

An honest comparison covers total cost of living rather than tax alone, and the ranking frequently changes when it does.

Establishing residency properly

Where people get into trouble.

Changing state tax residency requires actually changing domicile, not simply spending time elsewhere.

States with income taxes have an interest in retaining high-income residents and do audit claimed changes of residency.

The factors generally examined include where you spend your days, where your permanent home is, where you are registered to vote, where vehicles are registered, where your professional and personal connections are, and where your significant possessions are kept.

Day counts matter and are not the only test. Someone who spends the required days in a new state but retains a home, doctors, clubs and family connections in the old one may still be found to be domiciled there.

Keeping contemporaneous records — travel documentation, day counts — is worth doing during the transition rather than reconstructing later.

The non-financial factors

Which determine whether the move works.

Proximity to family, particularly grandchildren, is the factor most commonly cited by people who relocate and then relocate back.

Existing social networks, which take years to rebuild.

Healthcare access, especially specialist care for existing conditions.

Climate, which people frequently misjudge based on holiday experience rather than year-round living.

Whether the location remains suitable when driving is no longer possible, which is a consideration for a location chosen at sixty-five and occupied at eighty-five.

Testing it

The practical recommendation.

Rent before buying, for a full year including the least pleasant season.

A substantial proportion of retirement relocations are reversed, and the costs of buying and selling twice are considerable.

Renting first costs little and provides information that no amount of research supplies.

Splitting the year

A common arrangement with specific pitfalls.

Spending part of the year in each of two states does not automatically mean paying tax in the lower-tax one.

Domicile is the governing concept, and day counts are only one of the factors examined.

Both states may assert a claim, which can result in filing in both, with credits generally preventing genuine double taxation but adding complexity.

Where the arrangement is intended to change tax residency, contemporaneous records of days spent, and consistent evidence across voting, licensing, banking and healthcare, matter considerably more than the calendar alone.
