Arizona 1099 Tax Rules
- Rate applied here
- 2.5% Flat Rate
- Statutory bracket
- Single 2.50% rate
Arizona completed its move to a single 2.50% flat rate by 2024 after decades of bracket-based taxation. Proposition 110 in 2018 mandated the transition, and by 2025 the state had fully replaced graduated brackets with one rate applied to all taxable income.
Local taxes: No local income tax in Arizona. Cities cannot levy an income tax on wages, so a Phoenix- or Tucson-based contractor faces the same 2.50% as anywhere else in the state.
State revenue agency: Arizona Department of Revenue.Arizona has no state quarterly estimated tax voucher for individual income tax. Federal Form 1040-ES remains your only estimated payment.
Tax Strategy for notary publics
A notary's two core costs are the state commission renewal fee and the required journal, seal, and insurance. These are fully deductible and are easy to overlook precisely because they are small and routine. Notaries who also perform loan signing add document preparation time, mobile-notary travel mileage, and business insurance to the deduction schedule.
Mobile notary work is often the higher-margin and more seasonal part of the trade, with signing volume tied to the home purchase cycle. Loan-signing income can appear in a single month and then vanish for a quarter, so divide the trailing-twelve-month total rather than extrapolating a strong signing month.
To avoid underpayment penalties, pay at least 90% of your current-year tax, or 100% of last year's total tax — 110% if your prior-year AGI was above $150,000.

Frequently Asked Questions: Notary Publics Taxes in Arizona
Set-aside rates, deadlines and deductions for Arizona, tax year 2026.
How much should a notary public set aside for quarterly taxes in Arizona?
Set aside about 18.0% of everything you bill — 18.0% of $54,000 in gross income is $9,711 a year, or $2,428 per quarter. That total covers self-employment tax (15.3% on 92.35% of net profit), federal income tax on the remainder after your standard deduction, and Arizona adds roughly 2.5% on your taxable Arizona income. The percentage is measured against gross income rather than net profit because that is the number that actually reaches your bank account and the number you can safely divert.
When are 1099 quarterly taxes due in Arizona for 2026?
IRS Form 1040-ES estimated payments for 2026 are due April 15 (Q1), June 15 (Q2), September 15 (Q3), and January 15, 2027 (Q4). Arizona has no state quarterly estimated tax voucher for individual income tax. Federal Form 1040-ES remains your only estimated payment.
What expenses can a notary public write off in Arizona?
Common write-offs for notary publics include loan signing mobile driving mileage, dual-tray laser printer & toner, notary bond & e&o insurance policy, paper, document clips & envelopes, official notary stamp & record journal. Because Arizona taxes self-employment income at 2.5%, each deduction reduces both your federal and your Arizona liability, so a deduction is worth more than its face value.
