Your federal tax bill gets all the attention, but the check you actually deposit each month is shaped just as much by the state you live in. Two people earning the same $85,000 salary can take home thousands of dollars more or less per year purely because one lives in California and the other lives in Texas. This state tax calculator shows you exactly how much of your salary goes to your state government, what your marginal and effective rates really are, and what you keep after state income tax.
Type your gross annual income, pick your state of residence, and choose your filing status. Every figure updates instantly so you can compare states side by side before your next move, raise, or job offer.
How to Use
- Enter your Gross Annual Income — your total salary or wages before any state or federal deductions. This is the number on your job offer letter, not your take-home pay.
- Choose your State of Residence from the dropdown. California and New York levy progressive income tax, while Texas and Florida charge no broad income tax on wages at all.
- Select your Filing Status — Single or Married filing jointly. Married filers get a representative $5,000 deduction adjustment in this simplified model.
- Read the result card from the top down: the estimated state income tax owed for the year, your marginal state rate (the tax on your next dollar), your effective state rate (your total tax as a share of income), your income after state tax, and the monthly amount you keep.
The marginal rate is what matters when you decide whether to take on extra freelance work or a side gig. The effective rate is the truer picture of how much state tax you actually pay, because the first slices of your income are taxed at lower rates — or not at all.
State Code Reference
The state dropdown uses numeric codes. Pick the number that matches your state:
| Code | State | Representative Effective Rate | Marginal Rate |
|---|---|---|---|
| 1 | California | 8.8% | 9.3% |
| 2 | New York | 5.3% | 6.25% |
| 3 | Texas | 0% | 0% |
| 4 | Florida | 0% | 0% |
| 5 | Illinois | 4.95% | 4.95% |
These are 2024 representative averages, not the live bracket table. California and New York use graduated brackets; Texas and Florida charge no broad wage income tax at all.
California State Tax Calculator and Other States: How It Works
Forty-one states tax wage income, but they do it in very different ways. California uses a graduated bracket system that climbs as high as 12.3% at the top, New York applies its own progressive schedule on top of New York City's local levy, and a handful of states — Texas, Florida, Alaska, Nevada, Washington, Wyoming, South Dakota, and Tennessee — collect no broad tax on ordinary wages at all. A few states, like Illinois, take a single flat rate (4.95% for 2024) on every dollar you earn.
This simplified estimator applies each state's 2024 representative effective rate to your taxable income. It is built for quick, honest comparisons — not for preparing an actual return. The engine does not model graduated brackets, standard deductions, credits, or local taxes; it multiplies your taxable income by one flat representative rate per state. For an $85,000 single filer, California state tax lands near $7,480 (an 8.8% representative effective rate), New York near $4,505 (a 5.3% effective rate), and Texas $0, because Texas does not tax personal wages. That is a difference of nearly seven thousand dollars a year on the exact same salary.
A note on accuracy: the rates here are 2024 representative effective averages, not live bracket tables. California uses a graduated schedule that tops out above 12%, and New York's real effective rate on an $85,000 filer lands around 5–6% once its lower brackets and standard deduction apply. Texas and Florida genuinely charge $0 on wages. Treat every figure as a planning estimate within a few hundred dollars — confirm the exact bracket table for your year and city before filing or relocating.
Remember that state tax is separate from federal income tax and from FICA (Social Security and Medicare). Your employer withholds all three from your paycheck, but only the state portion changes when you cross a state line. Some states also tax retirement income or capital gains differently from wages, so if your income comes mostly from investments, check your state's specific rules.
Examples
Example 1 — The same salary, different coasts. A single software engineer earns $85,000. In California, estimated state income tax is $7,480, leaving $77,520 after state tax (an effective rate of 8.8%). In Texas, the state tax is $0, leaving the full $85,000. Relocating from California to Texas on the same pay raises after-state-tax income by $7,480 a year — before even accounting for housing costs.
Example 2 — The New York middle earner. A single filer in New York City earns $85,000. The state income tax is roughly $4,505, an effective rate of about 5.3%, leaving $80,495 after state tax. Note this excludes New York City's own local income tax, which can add several hundred dollars more for city residents.
Example 3 — The no-tax state move. A single filer earning $120,000 compares Florida and Illinois. Florida charges no wage income tax, so the state line stays at $0. Illinois applies a flat 4.95%, costing $5,940 a year. Choosing Florida keeps nearly six thousand extra dollars in the household budget. Married filers get a small standard-deduction adjustment in this simplified model, which trims the Illinois bill to roughly $5,690.
Example 4 — High earner stress test. On a $1,000,000 California income at the 8.8% representative effective rate, estimated state tax is $88,000, an effective rate of 8.8%, leaving $912,000 after state tax. This shows why very high earners in high-tax states sometimes weigh relocation: the absolute dollars at stake are enormous.
FAQ
What is the difference between marginal and effective state tax rate?
Your marginal rate is the tax applied to your next dollar of income — the top bracket your salary reaches. Your effective rate is your total state tax divided by your total income, which is always lower because the first portions of your income are taxed at lower rates or not at all. On an $85,000 California salary, the marginal rate is 9.3% and the representative effective rate is 8.8%.
Which US states have no income tax?
As of 2024, nine states have no broad income tax on wages: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire and Tennessee tax only interest and dividend income. Moving to one of these states can erase your state income tax entirely, though you may pay more in sales or property taxes.
How much is state tax on an $85,000 salary?
It depends entirely on your state. In California, an $85,000 single salary carries about $7,480 in state tax (8.8% effective). In New York, roughly $4,505 (about 5.3% effective). In Texas or Florida, the state tax is $0. Enter your exact income and state above for your personalized number.
Do I pay state tax if I work remotely across state lines?
Usually yes, in the state where you physically perform the work, though a growing number of states have reciprocal agreements. If you split your year between two states, you may need to file a part-year resident return in each. State tax residency rules are among the most complex parts of the tax code, so confirm with a professional if you cross state lines regularly.
Is state tax deducted from my paycheck automatically?
Yes. If your state has an income tax, your employer withholds it from each paycheck based on your W-4 and the state equivalent. At tax time, you file a state return to true up what was withheld against what you actually owe. If too much was withheld, you receive a state refund.
Does this calculator include federal tax?
No. This tool estimates only your state income tax. Your federal income tax, Social Security, and Medicare are separate. For a blended take-home pay estimate that stacks federal tax and FICA on top, use a dedicated paycheck or take-home-pay calculator.
