The scariest moment of your first year of gig work isn't a bad rating or a slow Saturday — it's April, when you learn nobody was withholding taxes from your Uber, DoorDash, or freelance income all year. If you're asking "how much should I set aside for taxes?", here's the short answer, then the exact math.
The quick answer: set aside 25–30% of your net self-employment income (profit after deductions). Big mileage deductions can pull that down toward 15–20%; high income or a state income tax pushes it toward 30–35%.
Why 1099 Taxes Hit Harder Than W-2 Taxes
When you work a W-2 job, your employer quietly withholds income tax and pays half of your Social Security and Medicare. As a 1099 contractor, both jobs are now yours:
- Self-employment tax (15.3%) — the full Social Security and Medicare bill, both the "employee" and "employer" halves.
- Federal income tax — on your profit, at your bracket.
- State income tax — in most states, a few extra percent.
Self-employment tax alone applies to 92.35% of your net earnings at 15.3% — effectively about 14.1% of your profit before you've paid a dollar of income tax. That's the piece that blindsides first-year gig workers.
The Set-Aside Table: Percent by Income Level
These are ballpark combined rates (self-employment tax + federal income tax) for a single filer taking the standard deduction, applied to net self-employment income. Add your state's income-tax rate on top.
| Net 1099 profit | Set aside (federal + SE tax) | Roughly per $1,000 earned |
|---|---|---|
| Under $15,000 | 15–18% | $150–$180 |
| $15,000 – $40,000 | 20–25% | $200–$250 |
| $40,000 – $80,000 | 25–30% | $250–$300 |
| $80,000 – $150,000 | 30–35% | $300–$350 |
| Over $150,000 | 35%+ (talk to a CPA) | $350+ |
Two things change these numbers a lot: other household income (a W-2 job or a working spouse pushes your bracket up) and deductions (which pull the whole bill down — more on that below).
Gross vs. Net: The Mistake That Costs Drivers Thousands
You owe tax on profit, not on what the app deposited. A delivery driver who grossed $45,000 and drove 20,000 business miles gets a mileage deduction of $14,500 at the 2026 IRS rate of 72.5¢ per mile. Their taxable profit is $30,500 — not $45,000.
Worked example: full-time delivery driver
- Gross 1099 income: $45,000
- Mileage deduction (20,000 mi × 72.5¢): −$14,500
- Phone, hot bags, supplies: −$1,200
- Net profit: $29,300
- Self-employment tax (~14.1%): ≈ $4,140
- Federal income tax (after standard deduction): ≈ $1,600
- Total set-aside ≈ $5,700 — about 19% of net, or just 13% of gross
Skip the mileage log and the same driver would compute taxes on $45,000 — roughly $4,400 more tax owed. Tracking miles isn't bookkeeping busywork; it's the single biggest lever on the number you set aside.

The IRS wants its money as you earn it, in four installments (Form 1040-ES):
| Quarter | Income earned | Payment due |
|---|---|---|
| Q1 | Jan 1 – Mar 31, 2026 | April 15, 2026 |
| Q2 | Apr 1 – May 31, 2026 | June 15, 2026 |
| Q3 | Jun 1 – Aug 31, 2026 | September 15, 2026 |
| Q4 | Sep 1 – Dec 31, 2026 | January 15, 2027 |
The safe-harbor rule (your penalty shield)
Estimating is hard when income swings week to week. The IRS won't penalize you if your quarterly payments total at least:
- 90% of this year's tax, or
- 100% of last year's tax (110% if your prior-year adjusted gross income was over $150,000).
First full year of gig work? The "100% of last year" option is usually the easiest target: take last year's total tax from your return, divide by four, and pay that each quarter — even if this year's income ends up higher, you're penalty-proof.
How to Shrink the Number You Set Aside
Every legitimate deduction reduces both income tax and self-employment tax — each $1,000 of deductions saves most gig workers $250–$400. The big ones:
- Mileage — 72.5¢ per business mile in 2026. For most drivers this is 60–80% of all deductions. (New to logging? Start with how to track mileage for taxes and the IRS mileage log requirements.)
- Phone & data plan — the business-use share, typically 50–80% for gig workers.
- Home office — $5 per square foot (up to 300 sq ft) with the simplified method.
- Supplies & gear — hot bags, phone mounts, chargers, cleaning supplies, uniforms.
- Half of your self-employment tax — deducted automatically on your 1040.
- Health insurance premiums — if you're not eligible for an employer plan.

A Simple System That Actually Works
- Open a separate savings account — nickname it "IRS." Out of sight, out of temptation.
- Move your percentage on every payout. Get paid $600, move $150–$180 the same day. Consistency beats precision.
- Track every mile and expense as they happen — reconstructing a year in April loses money and won't survive an audit.
- Pay quarterly from the IRS account at irs.gov/payments — it takes five minutes.
- Adjust twice a year. If the account is growing much faster than your estimate, your percentage is too high — that's your money sitting idle.

How much should I set aside for taxes as a 1099 worker?
A safe rule of thumb is 25–30% of your net self-employment income (after deductions). Lower earners with big mileage deductions may land closer to 15–20%; higher earners or those in states with income tax should lean toward 30–35%.
Do I set aside a percentage of gross or net income?
Net. You pay tax on profit — what's left after business deductions like mileage, supplies, and phone costs. Applying your percentage to gross overshoots, sometimes by thousands. Track deductions first, then set aside from what remains.
What happens if I skip quarterly payments?
The IRS charges an underpayment penalty that works like interest on what you should have paid each quarter. Use the safe-harbor rule — pay 100% of last year's tax (110% for high earners) in equal quarterly installments — and you're protected no matter how the year ends.
I also have a W-2 job. Do I still need to pay quarterly?
Maybe not. You can increase withholding at your W-2 job (file a new W-4) to cover your side-gig taxes instead of making quarterly payments. Withholding is treated as paid evenly through the year, which makes it a handy catch-up tool late in the year.
What if I can't afford the taxes I owe?
File on time anyway — the failure-to-file penalty is ten times the failure-to-pay penalty. The IRS offers payment plans (installment agreements) that most gig workers qualify for online in minutes.
