California Part-Year Resident Taxes: What You Owe in the Year You Move to Nevada

The year you move from California to Nevada, you will file a California tax return one more time, but only for part of the year. California taxes you on everything you earned while you were a California resident, and only on California-source income after you leave. Here is how that actually works, straight from the Franchise Tax Board's own rules, plus what it means for your Nevada fresh start.

Are You a Part-Year Resident?

Under California law (Revenue and Taxation Code §17015.5), a taxpayer who moves out of state mid-year is a part-year resident: a California resident for part of the tax year and a nonresident for the rest. Your move date splits the year. While you were a California resident, all income from all sources is subject to California tax. After you become a nonresident, only California-source income (think California wages, rental income from a California property, or California business income) is taxable. Nevada-source income after your move is not, because Nevada has no state income tax.

You File Form 540NR, Not Form 540

Part-year residents must file Form 540NR, the California Nonresident or Part-Year Resident Income Tax Return, along with Schedule CA (540NR), which re-computes your federal income with California adjustments and apportions it between your residency period and your nonresidency period based on when income was actually received. FTB Publication 1031, Guidelines for Determining Resident Status, is the plain-language starting point, and your tax preparer will confirm which version applies to your move year.

The 9-Month Residency Presumption

Here is the rule that surprises people. Under R&TC §17016, if you spend more than nine months (more than 270 days, in aggregate) in California during the tax year, you are presumed to be a resident for that year, even if you moved to Nevada in the spring. The presumption can be overcome with evidence that your California time was only temporary or transitory, but the burden of proof is on you, so keep a calendar, keep receipts, and be honest with your preparer about your days in California.

There is also a helpful safe harbor for genuine nonresidents: under California Code of Regulations §17014(b), an individual who is domiciled outside California, maintains a permanent home there, and spends no more than six months in California during the tax year is generally treated as being in California only for temporary or transitory purposes. If your move is clean, well-documented, and final, this is the path most transplants should land on.

Residency Is About More Than Days

The FTB weighs your whole pattern, not just a day count. Factors include where your home is, where you work, where you keep your family, where your children go to school, where you register to vote, where your cars are registered, where you bank, and what you tell the world your intent is. A Nevada driver's license, Nevada vehicle registration, and Nevada voter registration within your first 30 days do more than satisfy Nevada law, they build the paper trail California will look at. Our becoming a Nevada resident checklist covers the 30-day deadlines for your driver's license and car registration, step by step.

What About Wages, Remote Work, and Your Old Property?

Three situations come up constantly. First, if you keep collecting a California W-2 from a California employer while living in Nevada, the FTB may still consider those wages California-source (and your remote work from Nevada post explains the sourcing rules and the strategies remote workers use). Second, if you keep your California home and rent it, that rental income stays California-source. Third, if you sell a California home after moving, capital gains on California real estate are generally California-source too. None of this reduces the value of the move, it just means the tax year of transition has a few moving parts, which is exactly why we recommend a qualified CPA who handles California-to-Nevada moves.

The Good News on the Nevada Side

While California collects one last partial-year return, Nevada collects nothing: no state income tax, no inheritance tax, no estate tax. From your first full year in Nevada, wages, investment income, and retirement distributions are all free of state income tax. The no state income tax page shows the annual savings at typical California incomes, how much you will save runs the full comparison, and the Nevada property tax guide covers the property side of your new tax picture, with county-level detail on the property tax savings page.

What to Do This Tax Season

• Confirm with a CPA that you will file California Form 540NR for your move year, not Form 540.
• Document your move date, your 2026 days in California, and the day you established Nevada residency.
• Finish your Nevada driver's license, vehicle registration, and voter registration inside the first 30 days after moving.
• Keep old W-2s and any California rental or sale paperwork together for Schedule CA (540NR).
