How Much to Set Aside for 1099 Taxes
Most 1099 contractors should set aside 25–30% of every payment for taxes — but the right number depends on your bracket, state, and whether you also have W-2 wages. Plug in your income to get an exact percentage and dollar target.

Where the set-aside goes
SS: $6,298 + Medicare: $1,473
Marginal — stacked on top of W-2 wages
The recommended set-aside covers federal income tax, the 15.3% self-employment tax, and state income tax. It does not include the standard 25% buffer most people add for safety — see the rule of thumb below.
Per-payment rule of thumb
Easiest way to do this without math each invoice: open a separate savings account, label it “Taxes,” and move 19.9% of every 1099 payment into it the day it lands. At quarterly deadlines, transfer from that account to the IRS via 1040-ES.
The 25–30% rule of thumb, decoded
The number comes from stacking three line items on top of every 1099 dollar of net profit:
- 15.3% self-employment tax. Social Security (12.4% up to the wage base of $168,600 in 2024) plus Medicare (2.9%, no cap), levied on 92.35% of net profit. Effective rate on gross profit lands at about 14.1%.
- ~10–22% federal income tax. Your marginal bracket — typically 12% if 1099 is your only income up to about $47K of net profit, 22% above that, and 24% past $100K. With W-2 wages, you start higher.
- 0–9% state income tax. Zero in Texas, Florida, Nevada, Washington, Tennessee, South Dakota, Wyoming, Alaska, New Hampshire. Up to 9–13% top rate in California, New York, Hawaii, Oregon, New Jersey, Minnesota.
Add the three together and you get a range from ~24% (low federal bracket, no state tax) to ~38% (high earner in California). The 25–30% guidance is the middle of that range — safe for most full-time freelancers, a little light for high earners in high-tax states.
Worked example: $60,000 of 1099 income, single, Texas
A single freelancer in Texas with $60,000 of 1099 income and $3,000 in business expenses. No W-2 job.
A 25% set-aside would over-save by about $2,600 — a refund at filing. A 30% set-aside would over-save by ~$5,600 — a bigger cushion but less working capital during the year. In California, this same scenario adds ~$1,400 in state tax, pushing the set-aside to ~23%.
Quarterly estimated payment deadlines
The money you set aside doesn't sit in savings forever — the IRS expects it in four installments through the year. Miss a quarter and the underpayment penalty (~8% annualized in 2026) starts ticking on the unpaid amount.
| Income period | Payment due |
|---|---|
| Jan 1 – Mar 31 (Q1) | April 15 |
| Apr 1 – May 31 (Q2) | June 15 |
| Jun 1 – Aug 31 (Q3) | September 15 |
| Sep 1 – Dec 31 (Q4) | January 15 (next year) |

Why self-employment tax is the biggest line
For most 1099 contractors at typical income levels, the 15.3% self-employment tax is bigger than the federal income tax bill. It catches people off guard because W-2 employees never see the full FICA number — their employer pays half (7.65%) and the other half is quietly deducted from each paycheck.
As a 1099 contractor you cover bothhalves. There is no withholding, no employer match, no quarterly deduction from a paycheck — just a 15.3% line that hits at filing if you haven't been setting aside for it. This is the single biggest reason a 25–30% set-aside feels “too high” until your first April surprise.
The deeper line-by-line breakdown is at self-employment tax and the comparison to income tax stacking is at SE tax vs. income tax.
Deductions that lower the set-aside
Every dollar of legitimate business expense reduces both your income tax and your self-employment tax — about 28–32 cents combined for someone in the 12% federal bracket. The categories most 1099 contractors under-claim:
- Mileage. 67¢/mile in 2024, 70¢ in 2025 — most rideshare and delivery drivers under-track this. Mileage deduction guide.
- Home office. Simplified method: $5/sq ft up to 300 sq ft ($1,500 cap). Actual method scales higher. Home office deduction guide.
- Self-employed health insurance. Above-the-line deduction for premiums on health, dental, and qualifying long-term care.
- Solo 401(k) or SEP IRA. Contributions directly reduce taxable income. Solo 401(k) contribution limits exceed $69,000 for 2024.
- Software, internet, phone (business share), professional dev, supplies. Each line individually small, collectively often $3K–8K of legitimate deductions.

The simplest workflow
- Open a dedicated “Taxes” savings account. A separate high-yield account at Ally, Marcus, Discover, or your existing bank. Keeps the money out of sight and earns 4–5% APY through the year.
- Move your set-aside on day-of-payment. The day a 1099 client pays you, immediately transfer the percentage (25–30% for most people; whatever the calculator above shows for you) into the Taxes account.
- Pay 1040-ES from that account quarterly.April 15, June 15, September 15, January 15. Pay via IRS Direct Pay or EFTPS. Don't skip a quarter even if you'll “catch up” later — the penalty is computed per quarter.
- Reconcile at year-end.Whatever's left in the Taxes account after the April filing is yours. If you set aside conservatively, this is usually a small surplus.
Frequently Asked Questions
Is 25% enough to set aside for 1099 taxes?
For most full-time 1099 contractors earning $30K–$80K of net profit with no other income, 25% covers the basics — but only barely. The 15.3% self-employment tax alone eats nearly that much. Once federal income tax kicks in at the 12% bracket, the true number is closer to 28–30%. If you have W-2 wages that already push you into the 22% federal bracket, your 1099 income lands there too — and 30–35% becomes the realistic target. The calculator above gives you the actual number for your situation.
How much should a 1099 contractor set aside in California / New York / a high-tax state?
Add roughly 5–9 percentage points on top of the federal-only number. In California, a 1099 worker earning $75K of net profit should plan on 33–35% rather than the 25–28% you'd use in Texas or Florida. The state tax stacks on the same taxable income as federal, so the marginal dollar is taxed twice. Use the state selector in the calculator — it pulls in current state income tax rates.
Do I have to set anything aside if I already have W-2 withholding?
Yes — W-2 withholding only covers your W-2 wages. Your 1099 income comes with no withholding at all, and it stacks on top of W-2 income in the brackets. A common shortcut: take your W-2 marginal bracket (e.g., 22%), add 15.3% for self-employment tax, add your state bracket, and that's the set-aside rate on the 1099 dollars. Or pull the number directly from the calculator with your W-2 wages entered.
What about business expenses — do I set aside on gross or net?
Set aside on net. Every $1 of legitimate business expense (mileage, home office, software, supplies, professional dev) lowers both income tax and self-employment tax by roughly 25–30 cents combined. If you track expenses well, you can shave 2–4 percentage points off the gross set-aside rate. The calculator above takes expenses as an input so the percentage you see is already net of them.
When do I actually pay the IRS the money I've set aside?
Quarterly, on April 15, June 15, September 15, and January 15. The IRS treats taxes as pay-as-you-go — waiting until April 15 of the following year triggers the underpayment penalty (currently ~8% annualized interest on each missed quarter). Pay through IRS Direct Pay (irs.gov/payments) or EFTPS (eftps.gov). See the full guide at /estimated-tax-payments.
Should I set the money aside in a regular savings account?
A separate high-yield savings account is the standard play — Ally, Marcus, Discover, and similar pay 4–5% APY in 2026. On a $20,000 average balance through the year, that's $800+ in interest you wouldn't get from a checking account. Don't park tax money in stocks or anything else with downside risk: the IRS doesn't accept 'the market was down' as a reason for an underpaid quarter.
Is the 30% set-aside rule actually a tax rate?
No — it's a savings target, not a tax rate. The actual rate you'll pay is usually 18–25% effective on gross 1099 income, but the 30% set-aside builds in a buffer for state tax, the SE tax surprise, and the fact that your business expenses might be lower than you hope. Most contractors who follow the 30% rule end up with a small refund or a manageable April balance.
