For the year you moved to California, Form 540NR is the correct return, not Form 540.

I moved to California in November 2022 after living in Germany for the rest of that year, and my federal return for that year was filed as Form 1040NR, the nonresident return. Now my tax preparer is filing my California return as a full-year resident on Form 540, even though I lived in California for only part of the year. When I asked why it is not Form 540NR, they insisted Form 540 is correct but pointed to no rule. Is there a California rule that makes Form 540 right here, or should I push back and ask for Form 540NR?

No California rule makes you file a full-year return for the year you moved.

Maybe a preparer put you on Form 540 and could not point to a rule for it. For the year you moved to California, the rule points the other way, to Form 540NR. Which form you file does not depend on where you came from. It depends on one fact: whether you were a California resident for the entire tax year. California decides residency under its own law. You are a resident if you are in California for more than a stay, or if California is your . By that test you became a California resident when you moved, so for the year you moved you were a resident for part of the year and a nonresident for the rest.

If you filed your federal return as a nonresident, for example on , that does not decide your California form either. California does not borrow the federal nonresident rules or your immigration status. Its own guide and tax code define a California resident on their own terms, so a federal nonresident return neither forces Form 540 nor forces Form 540NR. The California form follows the California residency test alone.

Form 540 would tax the money you earned before you moved to California.

The two forms tax different amounts. Form 540, the full-year resident return, treats everything you earned all year as California income, including what you earned before you moved to California, in another state or another country. Form 540NR taxes your worldwide income only for the months you were a California resident, plus any for the rest of the year.

So if you had no California income before you moved, California does not tax that earlier income when you file Form 540NR, but it does when you file Form 540. The Reed Corporation, a California CPA firm, puts it this way: "People who move mid-year almost always file a 540NR, not a 540, and getting that wrong is one of the more common amended-return triggers we see."

Form 540 is the right form for a full year you live in California.

There is one situation where Form 540 is correct: a year you live in California from January through December. For a complete California year you are a full-year resident, and the full-year resident files Form 540. California even presumes you are a resident for any year you spend more than nine months in the state.

So the form depends on the specific year. The year you moved into California is a part-year return on Form 540NR. A later year you spend entirely in California is a full-year return on Form 540. If it is unclear which year's return this is, confirm that first.

下一步

If a preparer or tax software has you on Form 540 for the year you moved, here is how to get the right form, with the rule to point to.

Start here

Ask for Form 540NR for the year you moved.

Tell whoever prepares your return that you were a California resident for only part of that year, so the return should be Form 540NR, the California Nonresident or Part-Year Resident return, not Form 540.

Point to the FTB's own rule.

California's Publication 1031 sends a part-year resident to Form 540NR and keeps Form 540 for people who were residents the entire year. The Form 540NR instruction booklet says the same. Both are public FTB references you can show.

Check that your pre-move income is left out.

On Form 540NR, California should not tax the income you earned before you moved to California. If you had no California income before you moved, confirm the return taxes only your California months and any income from California sources.

Other people who moved partway through the year faced the same question: full year or part year? They filed the part-year return, and only the months they lived in the new state were taxed there. We can introduce you to them.

I worked in The Netherlands from January till the end of July and then moved to California (J-1 VISA for 2 years) from the end of August to now... Since I did not earn any money from worldwide sources while in California, it seems to me that I should not pay taxes on that.
