The one mental shift: you're taxed on profit, not pay
Spark doesn't withhold anything from your pay — it lands in your Branch or bank account in full. Come tax time you owe tax on your net profit: what you earned minus your business expenses. For most Spark drivers the giant expense is the car. In 2026 the IRS lets you deduct 72.5¢ for every business mile, so 10,000 Spark miles is $7,250 off your taxable income before you count anything else. Tracking miles is the single highest-paying habit in gig work — run yours through the mileage deduction calculator to see what they're worth, or read how the rate works in the 2026 IRS mileage rate guide.
Spark's wrinkle: Curbside vs Shopping & Delivery
Spark hands you two kinds of order, and they don't deduct the same. On a Curbside order, Walmart associates have already shopped the items — you load up and drive, so almost your whole order is deductible driving. On a Shopping & Delivery order you shop the aisles yourself first, and that in-store time earns no deductible miles, exactly like an Instacart batch. Same dollar of pay, different write-off: a long in-store shop with a short drive leaves you a smaller mileage deduction than a pure Curbside run. It doesn't mean one is "better" for taxes — it means you should log the driving portion of every order, because that's the part the IRS lets you deduct. See your true rate after the car and the IRS on the Spark driver pay calculator.
The two taxes you actually pay
Self-employment tax — 15.3%. This covers Social Security and Medicare (the half an employer would normally cover for you). It applies to 92.35% of your net profit and kicks in once profit hits $400 for the year. There's no standard deduction against it — it bites from the first dollar of profit, which is the number that surprises most new Spark drivers in April.
Federal income tax — your bracket. Layered on top, after deducting half your SE tax and your standard deduction. Many part-time Spark drivers owe little or no income tax but still owe the full 15.3% SE tax. State income tax may apply too; see how it changes your real hourly rate in California, Texas, Florida, New York, or Washington.
What changed for 2026 — № 1: the $2,000 1099 threshold
Starting with 2026 payments, companies only have to issue a 1099-NEC once they've paid you more than $2,000 in the year (it was $600). The 1099-K threshold for payment apps also went back up to $20,000 and 200 transactions (full breakdown: the 2026 1099-K threshold →). Two things to understand:
First, no form ≠ no taxes. Every dollar is taxable whether or not a 1099 shows up — the IRS expects you to report it all, and SE tax starts at $400 of profit. A weekend Spark driver who clears a couple thousand dollars may get no form this year and still owes tax on every dollar. Second, with fewer forms arriving, your own records become the source of truth. Keep a simple weekly record of earnings and miles — the free weekly log does this on your device, no account needed.
What changed for 2026 — № 2: the tips deduction
Under the 2025 tax law, workers in tipped occupations can deduct up to $25,000 per year of qualified tips from their federal taxable income (tax years 2025–2028). App- and platform-based delivery people appear on the IRS tipped-occupation list, and tips are a large share of Spark pay — often a quarter to half of what a driver takes home — so in-app Spark tips are generally expected to qualify. The fine print that headlines skip:
It reduces income tax only — you still pay the full 15.3% SE tax on tips. It phases out above $150,000 of income ($300,000 joint). And for self-employed workers the deduction can't push your business below zero, so high-mileage drivers with big deductions may not be able to use all of it. Still: if a third of your Spark income is tips, this is a meaningful cut to your income-tax bill. Platforms are now required to report tip totals separately, which is what you'll use to claim it when you file.
Quarterly payments: the four dates
Because nothing is withheld, the IRS wants tax through the year if you'll owe $1,000+: April 15 · June 15 · September 15, 2026 · January 15, 2027, paid online at IRS Direct Pay. Underpaying can mean penalties — though paying 100% of last year's total tax (110% for high earners) is a safe harbor. Have a W-2 job too? You can raise your W-2 withholding instead of paying quarterly. Get your number from the quarterly tax calculator.
The 15-minute system that handles all of this
Track every Spark driving mile from the moment you head to your first pickup (an app or a notes file — anything beats memory), and note which orders were Shopping & Delivery so you don't over-claim in-store time. Log each week's earnings and miles in the weekly log. Move 25–30% of profit into a separate account as you earn it. Pay quarterly from that account. And once a month, check your true hourly pay — or compare apps — to make sure the work still beats the alternatives after the car and the IRS take their cut.
Run more than one app? The rules rhyme across platforms but the forms and quirks differ: DoorDash Taxes (2026), Instacart Taxes (2026), and Uber Eats Taxes (2026).
