The state charge that does not apply to you
This is the part freelancers get wrong most often, and it runs in your favour here. Arizona has no wage-based payroll programme (disability or paid family leave) beyond the income tax, so there is no hidden payroll deduction to strip out of this calculation. If a “freelancer tax calculator” shows Arizona withholding a disability premium from your invoice income, it is running a W-2 payroll model against 1099 income.
Same $75,000, employee versus freelancer, in Arizona
| W-2 employee | 1099 freelancer | |
|---|---|---|
| FICA / self-employment tax | $5,738 | $10,597 |
| Federal income tax | $7,670 | $4,898 |
| Arizona state tax | $1,666 | $1,666 |
| Keeps | $59,926 | $57,839 |
| Gap | The freelancer keeps -$2,087 — this is the employer half of FICA, plus the QBI deduction working in the opposite direction. To match the employee’s$59,926 the freelancer needs to invoice about $97,253 at this state’s rates. | |
The gap is not a mistake in either calculation. The employee’s half of Social Security and Medicare is paid by the employer and never appears on the pay stub; the freelancer pays both halves and then deducts half of it on the 1040. Net effect: roughly 7.65% of income, partly clawed back by the deduction and the QBI allowance.
What Arizona actually charges on self-employment income
The Arizona wage tax is a single 2.5% figure rather than a schedule. By top rate, this state ranks 42nd of the 42 taxing jurisdictions compared here.
Top marginal rate in this state: 2.50%. The state taxes net profit, not gross billings — which is why the state line here is smaller than a wage-based estimate would suggest once you have real expenses. At $75,000 of net profit this page assumes no further deductions beyond the standard deduction; a freelancer with a home office, mileage or equipment would show less.

Questions this page answers directly
- Do I owe Arizona tax on invoices I have not been paid for yet?
- Generally you report income when you have a right to it, not when the money lands. Cash-basis taxpayers report when paid; accrual-basis when invoiced. The state follows the federal method you use.
- Do I need to make quarterly payments in Arizona as well as federally?
- Yes if you expect to owe more than the state's threshold at filing. Most states mirror the federal quarterly dates (April, June, September, January) but have their own forms and their own underpayment penalty.
- Can I deduct the state tax I paid on my federal return?
- Only as an itemized deduction, and state income tax is subject to the SALT cap. Most freelancers take the standard deduction, in which case the state tax gives no federal benefit at all.
- Is the 15.3% the same in every state?
- Yes — self-employment tax is entirely federal. Only the state income tax line changes from state to state, which is why the state share above is the only number that differs across these 51 pages.
