Retiring Out of California: Taxes, Healthcare, and Where to Go

Why retirees leave California

Retirement often removes the one thing tying someone to a California paycheck: the job. Once income is coming from Social Security, a pension, or retirement accounts rather than California wages, many retirees find the math of staying becomes harder to justify — especially if family has already scattered, housing equity could fund a much larger home elsewhere, or the goal is simply a lower cost of living on a fixed income. See cost of living comparisons and best states to move to from California for a broader starting point.

None of this is only about taxes. Climate, proximity to grandchildren, downsizing to a more manageable home, and healthcare access all factor in. But tax treatment of retirement income is one of the few genuinely state-specific variables worth modeling carefully before you commit, because it compounds every year you're retired.

The federal rule that protects your pension from your old state

A federal law, 4 U.S.C. § 114, generally prohibits a state from taxing retirement income paid to a nonresident, once that income is attributable to services performed in that state. In plain terms: if you worked for a California employer and earned a CalPERS or CalSTRS pension, California generally cannot tax those pension payments once you've established residency in another state, even though the pension was earned entirely in California. The state you now live in is what generally governs how (and whether) that income is taxed.

This also generally applies to qualified retirement plans like 401(k)s and IRAs: once you're a nonresident, the state is usually your new state of residence, not California, even though the funds accumulated there. This is a meaningful point many people get wrong — they assume California will keep taxing a CalPERS pension forever because it was a California job. Usually that's not how it works once you've genuinely relocated and established residency; see establishing residency in a new state for what that requires.

How the 12 states tax retirement income

The table below is a starting point for comparing the states most commonly covered on this site. Every cell should be verified against current state tax authority guidance before you rely on it — state tax treatment of retirement income changes periodically, including recent multi-state trends toward eliminating Social Security taxation.

Several of these states have no broad-based personal income tax at all (Texas, Nevada, Florida, Washington, Tennessee), which simplifies the picture considerably. Where a state does tax income, many offer age-based exclusions, retirement income credits, or partial exemptions that can substantially reduce the effective rate on Social Security or pension income even when it's technically 'taxable'.

Planning the actual move

Medicare and healthcare when you move

Healthcare is one of the most consequential and least-planned-for parts of a retirement move. The rules differ sharply depending on what kind of Medicare coverage you have.

Original Medicare travels with you

Original Medicare (Parts A and B) is a federal program and works the same nationwide — you can see any provider who accepts Medicare in your new state without needing to change plans. If this is your only coverage, moving out of state is administratively simple: update your address with Social Security and Medicare.

Medicare Advantage and Part D are regional

Medicare Advantage (Part C) plans and standalone Part D prescription drug plans are sold by private insurers within defined service areas, typically by county. Moving outside your plan's service area ends your ability to use that plan, and triggers a Special Enrollment Period that lets you pick a new Medicare Advantage or Part D plan in your new location without waiting for the general open enrollment window. You generally need to notify your plan and enroll in a new one around your move, not wait.

Medigap can be trickier

If you have a Medigap (Medicare Supplement) policy, moving across state lines can affect your guaranteed-issue rights to buy a new Medigap policy without medical underwriting, and pricing/availability of Medigap plans varies significantly by state. It's worth contacting your current Medigap carrier and a licensed Medicare advisor in your destination state before you move, not after.

If you're not yet Medicare-eligible and are relying on marketplace or employer coverage, see health insurance when leaving California for that separate set of considerations.

Estate and inheritance taxes in destination states

California has no state estate or inheritance tax. Most of the 12 states commonly covered here also don't, but estate and inheritance tax rules vary by state and change periodically, so this is worth a one-time check if you have a larger estate or expect to inherit from someone living in a state with such a tax. Note the distinction: an estate tax is charged against the estate before distribution; an inheritance tax is charged to the person receiving the inheritance, and in some states depends on their relationship to the deceased.

This rarely changes a decision to move on its own, but it's a legitimate line item for an estate planning conversation, particularly if you're also changing where your will or trust should be administered after you establish residency elsewhere.

Property tax relief for seniors in destination states

Many states and counties offer property tax relief programs aimed at seniors — homestead exemptions, assessed-value freezes once you reach a certain age, or circuit-breaker programs tied to income. These are usually administered at the county or local level, with eligibility based on age (often 65), income thresholds, and sometimes how long you've owned the home.

If property tax relief is part of your decision, it's worth calling the county assessor's office in the specific city you're considering rather than relying on statewide generalizations — these programs vary block to block in some states.

• Ask whether the exemption applies automatically or requires an annual application.
• Ask whether it's a flat exemption amount, a percentage, or a value freeze.
• Confirm residency and ownership-duration requirements before you count on it in your budget.

Being near family, and downsizing well

For many retirees, proximity to adult children and grandchildren outweighs tax considerations entirely, and that's a legitimate basis for a decision even if it's not the lowest-tax option on paper. If this is a driver for you, it's worth being candid with family about expectations before committing to a move near them — a move made primarily for proximity works best when it's a mutual decision, not an assumption.

Downsizing from a long-held California home often means letting go of decades of belongings at once. Give yourself more runway than feels necessary — sorting, selling, and donating takes longer than people expect, and doing it under deadline pressure leads to rushed decisions you may regret. A full-service mover that offers packing help can take some of the physical burden off, but the sorting decisions are still yours to make.

A hypothetical: a retired couple with a CalSTRS pension and a modest IRA are weighing Tennessee against Colorado. In Tennessee, the pension and IRA withdrawals would likely not be subject to state income tax; in Colorado, both might be partially taxed with an age-based subtraction that could shelter some income depending on their age and amounts. The better choice ultimately depends on the specifics of their income, not just a 'no income tax' headline.
