Maryland 1099 Tax Rules

- 4.75% Effective (Top 5.75%)
- Statutory bracket
- 2% to 5.75% plus mandatory county tax
Maryland's state top rate of 5.75% is only part of the liability. Maryland requires counties to levy a "piggyback" income tax of roughly 3% of the state rate, and 23 of 24 counties do, so a Maryland contractor effectively pays about 5.95% combined. Because counties may set their rate slightly lower, the total varies by county.
Local taxes: The mandatory county piggyback tax is the dominant local layer in Maryland and is not optional in practice. Baltimore City sets its own rates within the statutory band, so the same job pays a different total depending on the county line.
State revenue agency: Comptroller of Maryland.Maryland requires quarterly estimated payments via Form 502 if you expect to owe $1,000 or more, with the standard four federal deadlines. Maryland does not have its own separate voucher form.
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.
