How much lands in your bank account depending on pay schedule.
Biweekly (every two weeks, 26 pay periods) is not the same as semi-monthly (twice a month, 24 pay periods). Semi-monthly checks are slightly larger because there are two fewer of them per year.

Where every dollar goes
Here's the honest breakdown for a married filing separately filer on $170,000 in California (2026). The IRS takes $29,534 in federal income tax — that's after the $16,100 standard deduction knocks your taxable income down. FICA (Social Security plus Medicare, the combined line you always see on your pay stub) adds another $13,410. California collects $11,565 in state income tax, plus $2,210 for California SDI — that one is a separate deduction from your wages, not technically an "income tax."
Add it all up and $56,719 goes to taxes, leaving $113,281 in take-home pay. That's the number that actually lands in your bank account.

Frequently Asked Questions
What is the take-home pay on $170,000 in California?
For a married filing separately filer earning $170,000 in California (tax year 2026), the take-home pay is approximately $113,281 per year after $29,534 federal income tax, $13,410 in FICA (Social Security and Medicare), and $13,775 in state and local taxes. This is an effective tax rate of 33.36%.
Does this include pre-tax deductions like 401(k), HSA, or health insurance premiums?
The numbers on this page assume no pre-tax deductions. If you contribute to 401(k), HSA, healthcare FSA, or dependent care FSA, your actual federal tax will be lower. Use the live calculator to model exact pre-tax deductions — it applies them to your federal taxable wages and, for verified states (currently Pennsylvania, Michigan, and California), to your state taxable wages too.
Why does my actual paycheck differ from this estimate?
Common reasons: (1) pre-tax deductions your employer withholds — if you haven't entered them in the live calculator, your paycheck shows lower taxes; (2) W-4 withholding is an IRS safe-harbor estimate, not your true tax owed — you reconcile at filing; (3) state and local tax credits (EITC, property tax relief, child tax credit) that we don't model; (4) post-tax deductions like Roth 401(k) contributions or wage garnishments; (5) multiple jobs or side income changing your effective bracket.
What HSA contribution limit should I use — self-only or family?
The live calculator caps HSA input at the 2026 family limit ($8,750). If you have self-only HDHP coverage, your limit is $4,400 — enter no more than that. The age-55+ HSA catch-up contribution ($1,000) is not yet modeled. HSA contributions are pre-tax for FICA only when made through a §125 cafeteria plan (standard employer payroll deduction); standalone HSA contributions are post-FICA-tax.
Why is the Dependent Care FSA limit $7,500 now?
The One, Big, Beautiful Bill Act (signed July 2025) raised the Dependent Care FSA limit from $5,000 to $7,500 starting tax year 2026. For married filing separately, the limit is $3,750 (raised from $2,500). The live calculator applies the correct limit based on your filing status. This is the first DCFSA limit increase since 1986.
Can I add 401(k) or HSA catch-up contributions for older taxpayers?
Not yet. The live calculator exposes only the regular limits ($24,500 for 401(k), $8,750 for HSA family). Age-50+ adds $8,000 to 401(k) under §414(v); age-60-63 adds $11,250 under SECURE 2.0; age-55+ adds $1,000 to HSA under §223(b)(3). Catch-up support is on the roadmap; for now, treat the calculator's results as an upper bound on tax for older filers using catch-up.
What does 'verified' mean on this site?
A state or city is verified when its tax tables, rates, and brackets have been cross-checked against the official Department of Revenue publications for the given tax year. We list our primary-source citations on every page. Unverified jurisdictions are excluded from search indexing (with a noindex tag) and labeled "coming soon" — we don't show approximate data presented as authoritative. As of tax year 2026, six US jurisdictions are verified.
What is the difference between effective and marginal tax rates?
Your effective tax rate (33.36%) is your total tax divided by your gross income — the average percentage of your income that goes to taxes. Your marginal tax rate (43.15%) is the rate that applies to your next dollar of income. Marginal rates are always equal to or higher than effective rates in a progressive tax system.
Does California tax my HSA contribution?
Yes. California does not conform to federal IRC §223, so HSA contributions are added back to California taxable income under R&TC §17131.4 — even when made through a §125 cafeteria plan. California is one of only two states (with New Jersey) that does not recognize HSA pre-tax treatment for state income tax. The live calculator applies this correctly: your HSA contribution reduces federal taxable wages and FICA-taxable wages but not California state taxable wages. 401(k), healthcare FSA (via §125), and dependent care FSA (via §129) do reduce California state wages.
What is the 1% surtax on California income over $1 million?
California's Behavioral Health Services Tax (BHST), under R&TC §17043, adds a 1% surtax on California taxable income over $1,000,000. The surtax was renamed and repurposed by Proposition 1 (2024) effective tax year 2025. It is computed separately from the personal exemption credit, so the credit reduces your bracket tax but not the surtax portion. On taxable income of exactly $1,000,000 the surtax is zero; on $1,500,000 of taxable income it adds $5,000 (1% × $500,000 above the threshold).
Why is California SDI so high on my paycheck?
Starting January 1, 2024, California State Disability Insurance (SDI) has no wage base cap — the 2022 SB 951 law eliminated the §985 sunset, so the 2026 rate of 1.3% applies to every dollar of wages with no ceiling. A high earner at $500,000 pays $6,500 in SDI, at $1,000,000 pays $13,000, and so on. SDI funds short-term disability insurance and Paid Family Leave. Note: this calculator computes SDI on raw gross wages; in practice §125 cafeteria-plan deductions (healthcare FSA, DCFSA) reduce your SDI wage base slightly — we plan to model this in a future update. The current overstatement is bounded by 1.3% of your total §125 contributions.
What is California SDI?
California SDI is a mandatory employee-paid insurance contribution that funds short-term disability and paid family leave benefits. It is shown as a separate line item in the breakdown above ($2,210 annually on this salary).
What if I itemize federal deductions instead of taking the standard deduction?
This calculator applies the standard deduction ($16,100 for Married Filing Separately). If you itemize using IRS Schedule A — typically when your mortgage interest, state and local taxes (capped at $10,000), charitable donations, and qualified medical expenses exceed the standard deduction — your federal taxable income will differ. We don't model itemization because it requires line-by-line input and is highly individualized. Use IRS Schedule A worksheets or consult a tax professional for itemized scenarios.
How accurate is this calculator?
Federal income tax, FICA (Social Security + Medicare + Additional Medicare), and state income tax are computed from official 2026 IRS, SSA, and state Department of Revenue tables. This page assumes no pre-tax deductions, no itemized deductions, no tax credits, and W-2 wage income only. The live calculator supports 401(k)/HSA/FSA pre-tax deductions; itemized deductions, credits, self-employment income, and multi-state allocation aren't modeled.
