1099 Tax Calculator 2026

How this calculator handles your 1099 income

A 1099 contractor's tax return is one layer longer than a W-2 worker's, because expenses sit in the middle of it. This page starts from the number you already know — what you invoiced — instead of asking for your net profit up front:

1. Gross income − deductible expenses = net profit. Those are the two fields on screen, and the first line of your results shows the net figure (your Schedule C, line 31).
2. Self-employment tax is figured on net profit. Net profit × 92.35%, then 15.3% — Social Security up to its wage cap plus Medicare with no cap — and half of it comes back as an AGI deduction. Gross income and expenses both feed this layer, which is why expenses save more tax than most people expect.
3. Federal income tax applies to taxable income after the half-SE-tax deduction and the standard deduction, through the seven 2026 brackets (IRS Rev. Proc. 2025-32).
4. State tax. The nine states with no income tax on wages — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming — count as zero automatically. Everywhere else, the rate field is yours: enter a rate you have looked up, and the results label it "your input" rather than our estimate.

For the deep math of the 15.3% itself — the 92.35% factor, sharing the $184,500 Social Security cap with W-2 wages, the deductible half — see the self-employed tax calculator. W-2 worker who wants a refund estimate? Use the income tax calculator.

Expenses are your sharpest tax tool

Same $75,000 of gross income: $12,989 of tax with $15,000 of expenses claimed, $17,101 with none — a $4,112 difference. That is a 27% effective discount on every documented business dollar (single filer, standard deduction, Texas — computed by the same engine behind the calculator above).

The reason is stacking: one expense dollar skips both tax layers at once — self-employment tax (about 14.1% marginal after the 92.35% factor) and income tax at your bracket. Common legitimate deductions for 1099 workers:

• Software subscriptions, cloud services, and a business share of phone and internet
• Home office — actual expenses by square footage, or the simplified $5 per square foot up to 300
• Equipment, professional fees (legal, accounting), and continuing education
• Business insurance, advertising, and travel including mileage

The line is just as simple: ordinary and necessary business costs, with records. Dressing up personal spending as business expense is the most common — and most audited — 1099 filing mistake.

Quarterly taxes: the part 1099 workers can't skip

No employer withholds for you, so the IRS expects payment as you earn. Estimated payments are due four times a year: April 15, June 15, September 15, and January 15 of the following year, covering each quarter's income.

Two safe harbors keep you penalty-free — meet either one: pay in 90% of this year's tax, or 100% of last year's (110% if last year's AGI topped $150,000). The calculator's suggested payment is this year's estimate × 90% ÷ 4. If your income swings quarter to quarter, Form 2210's annualized method lets you match payments to when you actually earned the money instead of paying even quarters on an uneven year.

Which inputs move your result the most

1. Expenses. See above — $15,000 of them moved the example by $4,112. The highest-leverage field on this page.
2. Retirement contributions. SEP-IRA and Solo 401(k) contributions come straight off net profit (the SEP limit is 25% of net profit for 2026) — tax savings now, savings for later.
3. Filing status. Joint brackets and the $32,200 standard deduction are nearly double the single ones; if a spouse has W-2 wages, add them under Advanced options so the engine handles the cap-sharing correctly.
4. Your state. The gap between a no-income-tax state and a high-rate one can run to four figures on the same profit.

How to use this calculator

The page opens pre-filled with the $75,000 gross / $15,000 expenses example above, so there is a worked result on screen before you touch anything. Then make it yours:

1. Type your total 1099 receipts into Gross 1099 income (box 1 of Form 1099-NEC, or the sum across all of them).
2. Enter your total deductible costs in Business expenses — the results show your net profit immediately, plus a line comparing your tax bill against claiming nothing.
3. Pick your Filing status and State. Nine states count as zero automatically; elsewhere, fill the rate field with your actual rate from your state's revenue department or last year's return.
4. Have W-2 wages, retirement contributions, or payments already made? Open Advanced options and fill them in.
5. Read the results: total tax up top, then net profit, self-employment tax, income tax with its effective rate, state tax with its source label, take-home, and your marginal bracket. The Quarterly payment schedule table lays out all four due dates with the suggested amount for each.

Frequently asked questions

How much tax do I pay on 1099 income?

Two layers stack: self-employment tax of 15.3% (on 92.35% of net profit, once net earnings top $400) plus federal income tax from 10% to 37%. A single filer with $60,000 of net 1099 profit owes roughly $12,989 combined for 2026 — about 21.6% effective. Enter your own numbers above for the exact figure.

What percentage of 1099 income should I set aside for taxes?

A safe rule of thumb is 25%–30% of net profit: SE tax plus income tax lands near 25% at moderate incomes, more in high-tax states or brackets. The precise approach is the calculator's effective rate — total tax ÷ net profit — paid in on the quarterly schedule the results table shows.

What happens if I don't pay quarterly taxes?

The IRS charges interest on the underpaid amount, accruing per quarter. If you owe more than $1,000 at filing and missed both safe harbors (90% of this year's tax, or 100% of last year's — 110% at higher incomes), expect a penalty bill. In a volatile year, anchoring to 100% of last year's tax is the low-stress option: it requires no forecast.

What expenses can I deduct from 1099 income?

Anything ordinary and necessary for the business: software, equipment, a proportional home office (or the simplified method), mileage, insurance, professional fees, advertising, education. Personal costs don't qualify, and mixed-use items get split by business percentage. Keep receipts — expenses are the first thing an audit examines.

Is 1099 income taxed more than W-2 income?

On paper, yes — you pay both halves of the 15.3% payroll tax (a W-2 employer covers half), which adds roughly $4,500 at $60,000 of income. In practice, the expense deductions and higher retirement-plan limits available to contractors often close the gap or reverse it. That is exactly the comparison this calculator runs for you.

What is the $400 rule for self-employment tax?

If net earnings (net profit × 92.35%) are under $400, no self-employment tax is due. A small side gig often falls below it — but the income itself is still reportable, and regular income tax still applies.
