The Five Filing Statuses

California recognizes the same five filing statuses as the IRS, but there’s a wrinkle. If you’re in a registered domestic partnership (RDP) recognized by the state of California, you must file as married/RDP filing jointly or married/RDP filing separately. This has been the rule since 2007 under Cal. Rev. & Tax. Code Section 18521, and it applies even if the federal government treats you differently for some reason. Your filing status on Form 540 doesn’t have to match your federal return if you’re an RDP filer.

• Single — Unmarried, no dependents claimed as head of household. The default.
• Married/RDP Filing Jointly — You and your spouse or registered domestic partner combine everything onto one return. Almost always produces the lowest combined tax.
• Married/RDP Filing Separately — Each spouse files their own 540. This occasionally makes sense when one spouse has significant medical expenses or miscellaneous deductions, but it’s rare.
• Head of Household — Unmarried (or considered unmarried) and paying more than half the cost of keeping up a home for a qualifying person. Better brackets and a higher standard deduction than single.
• Qualifying Surviving Spouse/RDP — Available for two years after your spouse’s death if you have a dependent child. Same brackets as married filing jointly.

One mistake we see constantly: a taxpayer files as Head of Household on their federal return but forgets to verify they meet California’s requirements too. The rules are nearly identical, but California has its own form (FTB 3532) to substantiate the claim. If you’re audited, the Franchise Tax Board will ask for it.

Personal Exemption Credits (Lines 7-10)

Here’s where California goes its own way. The Tax Cuts and Jobs Act wiped out personal exemptions at the federal level starting in 2018. They’re gone from your 1040 entirely. But California never conformed to that change. The state still gives you an exemption credit for yourself, your spouse, and each dependent you claim, as provided under Cal. Rev. & Tax. Code Section 17054.

For 2025, each exemption credit is worth $144 according to the FTB Form 540 instructions. That’s not a deduction — it’s a dollar-for-dollar credit against your tax. It’s small, but it’s real money, especially if you have three or four kids. A family of six gets $864 in exemption credits right off the top.

How the Credits Break Down

• Line 7 — Personal exemption credit: $144 for yourself. Everyone gets this.
• Line 8 — Spouse/RDP exemption credit: $144 if filing jointly. If filing separately, only claim this if your spouse had zero gross income and isn’t claimed as a dependent elsewhere.
• Line 9 — Blind filing status: Check the box if you or your spouse are legally blind. This adds an additional $144 credit per qualifying person.
• Line 10 — Dependents: $144 per dependent, plus an additional $433 credit for each dependent under age 6 as of the end of the tax year. That under-6 credit is the young child tax credit component — don’t miss it.

The dependent exemption credit on Line 10 requires you to list each dependent’s name, SSN, and relationship. California follows the same qualifying child and qualifying relative tests as the IRS under IRC Section 152, so if someone qualifies as your dependent federally, they’ll qualify for California purposes too. The reverse isn’t always true for Schedule CA adjustment purposes, but for exemptions specifically, it’s a mirror.

Senior and Blind Additional Credits

If you or your spouse turned 65 before January 1, 2026, you’re entitled to an additional senior exemption credit on your Form 540. This is separate from the Line 7/8 personal exemption. Combined with the blind credit on Line 9, a married couple where both spouses are over 65 and blind would collect an extra $576 in credits before even getting to the tax calculation.

Don’t confuse this with the federal standard deduction increase for seniors. At the federal level, being 65+ gets you a bigger standard deduction per IRS Publication 501. In California, it’s a credit instead. Different mechanism, same general idea: the state gives older filers a small break.

Common Mistakes on Lines 1-10

We prepare hundreds of California returns every year at our Los Angeles office, and the same errors show up repeatedly on these lines:

• RDP filers choosing “Single” — If California recognizes your domestic partnership, you can’t file as single. Period.
• Forgetting the under-6 dependent credit — The extra $433 per young child is easy to overlook if you’re filling in the form manually.
• Not claiming the senior credit — Some tax software doesn’t prompt for it clearly. Double-check if you or your spouse crossed 65 during the tax year.
• Mismatching dependent counts — Your Form 540 dependent list should match your federal return unless there’s a specific California adjustment.

These lines set up your entire return. The exemption credits feed into your total credits on Line 43, and your filing status determines which tax rate brackets apply. If you’re unsure whether you qualify for Head of Household or whether your domestic partnership changes your filing status, sort that out before touching anything else on the 540.
