Staying in California or leaving in retirement is a question about tax rules, cost of living, and one large asset that most retirees own: the house. Each of these pieces moves differently, and the state-tax number by itself rarely tells the whole story.

This page lays out the trade-offs a California retiree faces, sourced from the Franchise Tax Board, the State Board of Equalization, the Internal Revenue Code, and the federal statute that shields nonresident retirement income. It does not recommend a choice. It gives you the numbers.

What the stay-or-leave decision actually changes

Three tax layers sit on top of a California retiree's income and assets: state income tax, property tax, and the future capital gains tax on inherited assets. A move to a no-income-tax state removes one of those layers. It affects the other two in less obvious ways.

The state income tax layer drops to zero on retirement income once you become a nonresident of California, under 4 U.S. Code Section 114. The property tax layer changes because the Proposition 19 base year value on a California home is not portable to another state. The capital gains layer changes if you leave a community property state before the first spouse's death.

Social Security sits outside the decision. California already exempts Social Security benefits from state income tax under Revenue and Taxation Code Section 17087, so staying or leaving does not change the state treatment of your Social Security check.

How California taxes retirement income

California taxes pensions, IRA distributions, 401(k) and 403(b) withdrawals, and 457 plan distributions as ordinary income at the same brackets that apply to wages. There is no California-specific retirement income exclusion for these sources.

The 2024 Schedule X brackets for a single filer run from 1 percent on the first 10,756 dollars of taxable income to 12.30 percent on income above 721,314 dollars. Married-filing-jointly brackets in Schedule Y double the thresholds, with the top 12.30 percent bracket starting at 1,442,628 dollars. Head-of-household brackets sit in Schedule Z. All three schedules are published in the FTB 2024 Form 540 booklet.

Roth IRA qualified distributions are not taxed by California, matching the federal treatment. A Roth conversion is taxed as ordinary income by California in the year of conversion, at the same Schedule X, Y, or Z bracket that applies to your other income for the year.

The Mental Health Services Tax above 1,000,000 dollars

California adds a 1 percent Mental Health Services Tax (MHST) on taxable income above 1,000,000 dollars. The tax sits at Revenue and Taxation Code Section 17043, enacted by Proposition 63 in November 2004 and operative January 1, 2005.

The MHST applies to the same taxable income figure reported on Form 540, line 19. It is computed on Form 540, line 62, using whole dollars. A retiree who realizes a large one-time IRA distribution, sale of a business, or capital gain that pushes taxable income above the 1,000,000-dollar threshold will pay MHST on the excess.

The MHST does not use its own bracket schedule. It is a flat 1 percent on the amount over 1,000,000 dollars, stacked on top of the regular Schedule X, Y, or Z tax. Combined with the 12.30 percent top marginal rate, the effective top California rate on income over 1,000,000 dollars reaches 13.30 percent.

The nine states with no individual income tax

Nine states impose no individual income tax on wages, pensions, or IRA distributions: Nevada, Texas, Florida, Wyoming, Washington, South Dakota, Alaska, Tennessee, and New Hampshire. The last of these, New Hampshire, repealed its interest and dividends tax in 2025, joining the true no-tax group.

Two nuances matter. Washington imposes a 7 percent capital gains tax on long-term gains above an annual threshold (adjusted for inflation), which touches taxable brokerage sales but not retirement account distributions or Social Security. Tennessee's prior Hall Tax on interest and dividends was fully repealed for tax years beginning January 1, 2021.

None of these nine states tax IRA distributions, 401(k) withdrawals, private pensions, or Social Security under their own income tax codes. Choice among them depends on cost of living, property tax, medical infrastructure, family location, and personal fit.

The federal shield on retirement income for nonresidents

The rule that stops a former state from taxing your retirement income after a move sits in federal law. It is 4 U.S. Code Section 114, enacted as Public Law 104-95 on January 10, 1996 and amended by Public Law 109-264 on August 3, 2006.

The statute reads in part: "No State may impose an income tax on any retirement income of an individual who is not a resident or domiciliary of such State." The federal definition of retirement income is broad.

It covers qualified trusts under IRC Section 401(a), 403(a) and 403(b) annuities, SEP IRAs under IRC Section 408(k), and IRAs under IRC Section 7701(a)(37). It also covers governmental 457(b) plans, section 414(d) governmental plans, and military retired pay under chapter 71 of title 10.

Once you are not a California resident or domiciliary, California cannot tax any of that income. For a retiree who holds precious metals in a self-directed IRA, the residency-change mechanics and clean-move sequence are covered in more depth on our page for leaving California in retirement with a gold IRA.

What leaving California costs on the family home

Proposition 19 sits at Revenue and Taxation Code Section 69.6, added by Senate Bill 539 in 2021. It lets a qualifying homeowner transfer the base year value of a principal residence to a replacement principal residence anywhere in California. Qualifying homeowners are those over 55, severely disabled, or victims of a wildfire or natural disaster. The base year value transfer became operative April 1, 2021.

The transfer is not portable to another state. A retiree who leaves California gives up the Proposition 19 option on that home. If the property was purchased decades ago and carries a very low factored base year value, that low tax basis dies with the sale.

Proposition 19 also changed the intergenerational transfer rules on February 16, 2021. The parent-to-child and grandparent-to-grandchild exclusion now applies only when the transferee makes the home a principal residence, and the exclusion is capped at factored base year value plus 1,000,000 dollars (biennially adjusted). The prior Proposition 58 unlimited exclusion is gone.

Community property step-up and the timing of the move

California is a community property state. Under Internal Revenue Code Section 1014(b)(6), when the first spouse dies, both halves of community property receive a stepped-up basis to fair market value at the date of death. In common-law states, only the deceased spouse's half gets the step-up; the survivor's half keeps its original basis.

For a couple who bought a California home in the 1980s and holds appreciated brokerage stock in community property, the double step-up can eliminate decades of embedded capital gain at the first death. A move to a non-community-property state before the first spouse's death, without proper titling, can lose that treatment on the assets acquired or retitled after the move.

Nevada, Washington, and Texas are community property states, so a move to those preserves the double step-up on assets held as community property. Florida, Tennessee, Wyoming, South Dakota, Alaska, and New Hampshire are not, though several offer optional community property trusts. Consult a licensed estate attorney before assuming the treatment.

Cost-of-living offsets when comparing states

The Missouri Economic Research and Information Center (MERIC) publishes a quarterly Cost of Living Index that aggregates C2ER ACCRA data with US=100 as the base. In the First Quarter 2026 release, California's composite index was 140.5, ranked 50th of 51 (with Hawaii at 184.8).

By comparison, Nevada's composite index was 100.7, Florida's was 100.7, and Texas's was 90.7. Housing is the largest driver of the California gap: the California housing sub-index sat at 189.5, while Nevada's was 110.5, Florida's was 101.1, and Texas's was 77.7. Grocery, utilities, transportation, health, and miscellaneous run closer to the national average across all four states.

The cost-of-living gap matters for retirees drawing a fixed pension and Social Security. A California retirement budget that requires 100,000 dollars per year would translate to about 71,700 dollars in Texas and 64,600 dollars in Oklahoma at the Q1 2026 index ratios, before any state tax adjustment.

Property tax treatment in California and no-tax states

California's Proposition 13 caps the base ad valorem property tax rate at 1 percent of assessed value, with additional amounts for voter-approved general obligation bonds and school facility bonds. Assessed value grows by no more than 2 percent per year until a change of ownership or new construction resets the base year value.

The nine no-income-tax states use different property tax structures, and the effective rate on a median-value home varies widely. Texas ranks among the highest effective rates in the country, driven by school district and county levies with no state income tax offset. Nevada, Florida, Wyoming, and South Dakota fall closer to the national middle. Tennessee and Alabama are among the lowest, but Alabama is not an income-tax-free state.

A retiree comparing states should look at the combined stack of income tax, property tax, sales tax, and vehicle registration fees on a realistic annual budget, not the headline state income tax rate alone. Local tax pages at each state's department of revenue are the primary sources for those figures.

Estimated tax payments in the year of a move

California residents must file Form 540-ES estimated tax payments if they expect to owe at least 500 dollars in state tax after withholding, or 250 dollars if married filing separately. The trigger is based on the prior year's liability or the safe-harbor thresholds in the FTB Form 540-ES instructions. The four quarterly installments have due dates on April 15, June 15, September 15, and January 15 of the following year.

In the year of a move, a retiree files Form 540NR (California Nonresident or Part-Year Resident Income Tax Return) and Schedule CA (540NR) to split California-source income and residency periods. Estimated payments made before the move date are credited against the California resident portion of the year.

The new state may impose its own estimated tax rules if it has an income tax, but the nine no-income-tax states listed above do not require estimated payments for individuals. Consult a licensed CPA for reader-specific numbers, filing status, and safe-harbor calculations.

How to sequence a stay-or-leave decision

The sequence below is a decision-making outline, not tax advice. It walks through the pieces that need to be settled before the choice becomes clear.

1. Add up your California retirement tax layer. Total your projected pension, IRA distribution, Roth conversion, and California-source rental or business income for the next three years. Apply Schedule X, Y, or Z to the ordinary income portion.
2. Estimate the Mental Health Services Tax exposure. If any single year projects taxable income above 1,000,000 dollars, add 1 percent on the excess to the state layer estimate.
3. Look up your factored base year value on the California home. The county assessor's office publishes the current factored base year value on your annual notice. Compare it to the fair market value.
4. Check whether Proposition 19 portability could serve you inside California. If you are age 55 or older, moving inside California preserves the base year value under RTC Section 69.6.
5. Model the cost of living in each candidate state. Use the MERIC Cost of Living Index (US=100) to convert your California budget to the candidate-state equivalent. Housing is the largest single driver.
6. Add the destination property tax layer. Look at the effective rate on a home in your target price range from the county assessor. Texas requires the closest attention because the effective rate is high.
7. Consult an estate attorney on community property. If you are married and hold appreciated assets, model the first-death step-up under both a California scenario and the candidate state scenario.
8. Check your Medicare and health care network. Medical continuity is often the largest hidden cost of a retirement move.
9. Ask a licensed CPA to review your specific numbers. This page uses agency-published figures. Your specific bracket placement depends on filing status, deductions, and other income.

When leaving California for the tax break is a bad idea

A move that clears on the tax page can fail everywhere else. Below are the cases where the state savings on retirement income do not justify the move.

• Your retirement income is modest. A retiree with 40,000 dollars of pension and 30,000 dollars of Social Security pays limited California tax because Social Security is exempt and the pension sits in the 8 to 9.3 percent brackets. The state savings may not cover moving costs and lost family proximity.
• Your family and medical network is in California. Grandchildren, longtime primary care doctors, established specialists, and community ties often outweigh a low-to-mid five figure annual tax saving, particularly past age 70.
• You own a low-basis California home with heavy embedded gain. A move before the first spouse's death can lose the community property double step-up on that asset. The lost step-up can dwarf several years of state income tax savings.
• You would give up a very low factored base year value. A California home purchased in the 1980s or 1990s often carries a factored base year value below 500,000 dollars. That low property tax basis dies with the sale and cannot be transferred to another state.
• The destination state has higher property tax or effective sales tax. Texas offers no state income tax but ranks among the highest property tax states. A high-value replacement home there can undo the income tax savings.
• You plan to keep the California home available for personal use. A retained California home used personally is one of the strongest counter-signals in a residency audit. It undoes most of the move on paper and may lose the treatment on your former state layer.
• You are trying to change residency without changing where you actually live. A mail-forwarding address, a South Dakota RV domicile without physical presence, or a friend's spare room without lease is not a principal residence. This is one of the fastest ways to fail a residency audit.

Stay-or-leave questions, answered

Does California tax my Social Security benefits?

No. California fully exempts Social Security benefits from state income tax under Revenue and Taxation Code Section 17087, which conforms out federal Internal Revenue Code Section 86. The exemption is confirmed in FTB Publication 1005, Pension and Annuity Guidelines. Federal tax on Social Security still applies up to 85 percent of benefits under IRC Section 86 based on provisional income.

What is California's top marginal tax rate on retirement income?

The top statutory bracket in the 2024 Schedule X, Y, and Z is 12.30 percent, reached at 721,314 dollars of taxable income for single filers, 1,442,628 dollars for married filing jointly, and 980,987 dollars for head of household. On taxable income above 1,000,000 dollars, the Mental Health Services Tax adds 1 percent under RTC Section 17043, taking the top effective rate to 13.30 percent.

Can a former state tax my IRA distributions after I move?

No, under federal law. Public Law 104-95, codified at 4 U.S. Code Section 114, bars any state from imposing income tax on the retirement income of a person who is not a resident or domiciliary of that state. The statute lists IRAs, pensions, 401(a) trusts, 403(a) and 403(b) annuities, SEP IRAs, 457 plans, and military retired pay by name.

Which states have no individual income tax?

Nine states: Nevada, Texas, Florida, Wyoming, Washington, South Dakota, Alaska, Tennessee, and New Hampshire. New Hampshire completed the repeal of its interest and dividends tax in 2025. Washington imposes a 7 percent capital gains tax on long-term gains above an inflation-adjusted threshold, which does not apply to retirement account distributions or Social Security.

Do I lose my Proposition 19 base year value if I leave California?

Yes on the transfer option. The base year value transfer under Proposition 19 (RTC Section 69.6) applies to a replacement principal residence anywhere in California, not outside the state. Selling the California home and buying out of state ends the option. If you buy inside California and use the transfer within two years of the sale, you keep the base year value under the eligibility rules.

What happens to community property step-up if my spouse dies after we move?

It depends on the destination state. If the new state is a community property state (Nevada, Washington, Texas, Arizona, New Mexico, Idaho, Louisiana, or Wisconsin), assets held as community property continue to qualify for the double step-up under IRC Section 1014(b)(6). If the new state is a common-law state, assets acquired or retitled after the move do not qualify for the double step-up on those assets. An estate attorney should be consulted.

How does cost of living compare?

The MERIC Cost of Living Index (First Quarter 2026, US=100) puts California at 140.5, Nevada at 100.7, Florida at 100.7, and Texas at 90.7. Housing drives most of the gap: California's housing sub-index is 189.5, while Nevada's is 110.5, Florida's is 101.1, and Texas's is 77.7. Non-housing categories run closer to the national average across all four states.

Do I need to file California estimated tax in the year of my move?

Possibly. If you expect to owe at least 500 dollars of California tax after withholding for the resident portion of the year (250 dollars if married filing separately), you must make estimated payments per Form 540-ES rules. In the year of the move, you file Form 540NR with Schedule CA (540NR) to allocate income between the California resident period and the nonresident period. Consult a licensed CPA for your specific safe-harbor calculation.
