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.

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.
