California vs Utah taxes

Lower income tax in California, then SDI

Neither state has a local income tax, so the difference is each state’s income tax and California’s payroll premium.

Income tax. California’s brackets start at 1% and stay below Utah’s 4.45% on the first $41,452 of taxable income. Utah taxes the whole salary at 4.45% and gives back a credit worth up to $966, which shrinks as income rises. So on ordinary pay California’s income tax is the smaller one: on $75,000 it is $2,775, against $3,103 in Utah. For a single filer that holds up to about $86,000.

SDI. California withholds State Disability Insurance at 1.3% of every dollar of wages, with no cap: $975 on $75,000. Utah has no payroll deduction at all.

SDI more than cancels California’s income tax advantage. A single filer on $75,000 keeps $646 more in Utah.

Close to level, then not close at all

There is a band of salaries where the two states come out almost even. For a single filer between $40,000 and $50,000 they stay within about $24 a year of each other, with California a few dollars ahead in places. For a couple filing jointly, whose brackets are twice as wide in California, the near-level band sits between $75,000 and $100,000, where the two stay within about $47 of each other.

Above that, California’s rates climb and Utah’s do not. California charges 9.3% from $72,724 of taxable income for a single filer and keeps rising to 12.3%, while Utah’s rate on each extra dollar falls to a flat 4.45% once its credit is used up. SDI keeps growing with the salary. So Utah’s lead widens fast: $1,905 on $100,000, $4,980 on $150,000 and $11,130 on $250,000. On $500,000 it is $28,218.

Working remotely for a California employer

California taxes a nonresident only on income from California sources, and for wages that means work physically performed in California. The Franchise Tax Board’s guidance for part-year residents and nonresidents splits a salary by the share of workdays spent in the state. A Utah resident working from home in Utah for a California company does not owe California tax on those days; days spent working in California are taxable there. Any California tax over-withheld after a move comes back on a Form 540NR.

What the take-home figure does not count

Utah’s withholding tables give a single filer only part of the credit during the year, so a single Utah paycheck can be slightly smaller than the table shows, with the difference refunded after filing. California’s exemption credit is withdrawn at high incomes, which these figures do not apply. Housing costs, property tax and sales tax are not in these figures.

Questions people ask

Do you take home more in California or Utah on $75,000?

Utah, by $646 a year, or $54 a month, for a single filer in 2026. That counts federal tax, Social Security, Medicare, state income tax and every state payroll deduction.

Is the difference the same at every salary?

No, but the same side stays ahead. The gap is $96 a year at $30,000 and $11,130 at $250,000, for a single filer.

If I move from California to Utah but keep my California employer, who taxes me?

Once you are a Utah resident, California taxes you only on California-source income, which for wages means work physically done in California. Days worked from home in Utah are not California wages, and Utah taxes its residents' income. If your employer keeps withholding California tax, ask for it to be changed.

Does Utah have anything like California's SDI?

No. Utah has no state disability insurance and no paid family leave program, and its unemployment insurance is paid by employers. State income tax is the only state deduction on a Utah payslip.

Does either state have a local income tax?

No. No city or county in California levies an income tax, and no Utah city or county does either. The figures here hold across both states.

What this comparison covers

Income tax and payroll deductions on wages: federal income tax, Social Security, Medicare, state income tax, every state payroll deduction. It does not compare sales tax, property tax, housing or the cost of living, which can outweigh the difference in take-home pay. Figures assume the standard deduction, no dependents and no pre-tax retirement contributions. See how we calculate.
