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 Instacart shoppers
Full-service shoppers carry a heavier deductible load than most gig roles: mileage between stores and homes, insulated totes, and often a second vehicle for over-capacity orders. Batch your store-to-home mileage by shopping region rather than by shopping trip, because the IRS treats a single errand run as one deductible journey and breaking it into too many segments invites scrutiny.
Shopper earnings concentrate around weekends and holidays, so quarterly income is very uneven. Set aside the target percentage at the moment of payout, including tips, because tip income on a 1099-K is reportable and the IRS matches it against your return.
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.

How much should a instacart shopper set aside for quarterly taxes in Arizona?
Set aside about 16.1% of everything you bill — 16.1% of $38,000 in gross income is $6,115 a year, or $1,529 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 instacart shopper write off in Arizona?
Common write-offs for Instacart shoppers include delivery & store mileage, mobile phone & data, insulated coolers & ice packs, folding grocery utility cart, lanyards & badge holders. 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.
