Nobody tells you this when you go 1099: you're now your own payroll department.
Your clients don't withhold anything. No federal tax comes out. No state tax. No Social Security. No Medicare. At the end of the year — or actually four times a year — you're responsible for cutting checks to the IRS and your state treasury on your own.
Most first-year freelancers and contractors find this out the hard way, usually around April 15th.
This guide lays out exactly how much you owe and what to set aside per quarter, for the ten most populous states in the US, across three income levels. The numbers below come directly from the 2026 1099 tax calculator — SE tax, federal brackets, state rates, all of it.
The Three Layers of 1099 Taxes
Before the tables, it helps to know what you're actually paying. As a 1099 worker, your tax bill has three parts.
1. Self-Employment (SE) Tax — 15.3%
This is the one that catches people off guard. W-2 employees pay 7.65% for Social Security and Medicare — but their employer pays the other half. As a 1099 worker, you are both the employee and the employer, so you pay both halves: 15.3%. It's applied to 92.35% of your net income (the IRS lets you back out the employer-equivalent portion before calculating).
- Social Security: 12.4% on the first $184,500 in earnings (2026 wage base)
- Medicare: 2.9% on all earnings, no cap
- Additional Medicare: 0.9% on earnings above $200,000
2. Federal Income Tax
Same brackets as a W-2 employee, but with one adjustment in your favor: you can deduct half of your SE tax from your gross income before calculating federal taxes. At $80,000 in self-employment income, that deduction is worth about $5,650 — real money.
3. State Income Tax
Nine states take nothing. The others vary from Pennsylvania's flat 3.07% to California's progressive rates that reach 13.3% at the top. For most 1099 earners, state tax is the second-biggest line item after SE tax.
The Math at Three Income Levels
All calculations below assume: single filer, standard deduction ($16,100 for 2026), no business deductions beyond the 50% SE deduction. State tax is estimated on the same taxable base as federal.
$50,000 Net Self-Employment Income
| SE Tax (15.3% × 92.35%) | $7,065 |
| SE Deduction (50% of SE tax) | –$3,533 |
| Adjusted Gross Income | $46,467 |
| Federal Taxable Income (after $16,100 std deduction) | $30,367 |
| Federal Income Tax | $3,396 |
| State | State Tax | Total Tax | % of Income | Per Quarter |
|---|---|---|---|---|
| Texas / Florida / Washington / Nevada / Wyoming | $0 | $10,461 | 20.9% | $2,615 |
| Ohio | ~$119 | $10,580 | 21.2% | $2,645 |
| Pennsylvania | ~$932 | $11,393 | 22.8% | $2,848 |
| North Carolina | ~$1,291 | $11,752 | 23.5% | $2,938 |
| Illinois | ~$1,503 | $11,964 | 23.9% | $2,991 |
| New York | ~$1,346 | $11,807 | 23.6% | $2,952 |
| Georgia | ~$1,637 | $12,098 | 24.2% | $3,025 |
| California | ~$597 | $11,058 | 22.1% | $2,765 |
Practical rule at $50k: Set aside 23–25% if you're in a tax state, 21–22% if you're in a no-tax state. That covers SE tax, federal, and state with a small buffer.
$80,000 Net Self-Employment Income
| SE Tax (15.3% × 92.35%) | $11,304 |
| SE Deduction (50% of SE tax) | –$5,652 |
| Adjusted Gross Income | $74,348 |
| Federal Taxable Income (after $16,100 std deduction) | $58,248 |
| Federal Income Tax | $7,527 |
| State | State Tax | Total Tax | % of Income | Per Quarter |
|---|---|---|---|---|
| Texas / Florida / Washington / Nevada / Wyoming | $0 | $18,831 | 23.5% | $4,708 |
| Ohio | ~$885 | $19,716 | 24.6% | $4,929 |
| Pennsylvania | ~$1,788 | $20,619 | 25.8% | $5,155 |
| North Carolina | ~$2,476 | $21,307 | 26.6% | $5,327 |
| Illinois | ~$2,883 | $21,714 | 27.1% | $5,429 |
| New York | ~$2,977 | $21,808 | 27.3% | $5,452 |
| Georgia | ~$3,140 | $21,971 | 27.5% | $5,493 |
| California | ~$2,120 | $20,951 | 26.2% | $5,238 |
Practical rule at $80k: Set aside 26–28% in a tax state, 24–25% in a no-tax state. You're deep enough into the 22% federal bracket now that the SE tax deduction is doing real work.
$120,000 Net Self-Employment Income
| SE Tax (15.3% × 92.35%) | $16,955 |
| SE Deduction (50% of SE tax) | –$8,478 |
| Adjusted Gross Income | $111,522 |
| Federal Taxable Income (after $16,100 std deduction) | $95,422 |
| Federal Income Tax | $15,705 |
| State | State Tax | Total Tax | % of Income | Per Quarter |
|---|---|---|---|---|
| Texas / Florida / Washington / Nevada / Wyoming | $0 | $32,660 | 27.2% | $8,165 |
| Ohio | ~$1,932 | $34,592 | 28.8% | $8,648 |
| Pennsylvania | ~$2,929 | $35,589 | 29.7% | $8,897 |
| North Carolina | ~$4,055 | $36,715 | 30.6% | $9,179 |
| Illinois | ~$4,723 | $37,383 | 31.2% | $9,346 |
| New York | ~$5,152 | $37,812 | 31.5% | $9,453 |
| Georgia | ~$5,143 | $37,803 | 31.5% | $9,451 |
| California | ~$5,416 | $38,076 | 31.7% | $9,519 |
Practical rule at $120k: Set aside 30–33% in a tax state, 28–29% in a no-tax state. At this income level, SE tax alone is nearly $17,000 — the single biggest line item on your tax bill.
State-by-State Notes
Texas, Florida, Washington, Nevada, Wyoming
No state income tax. For a 1099 worker, this is a genuine advantage. Living in Texas vs. New York at $120k means keeping roughly $5,150 more per year — money that would otherwise go to the state. Washington is particularly popular for tech contractors for exactly this reason.
California
California's progressive brackets mean the effective state rate at $50k is much lower than the 9.3% rate most people quote. At $50,000 net income, your CA state tax is around $597 — just 1.2% effective on gross. By $120,000, it climbs toward 4.5% effective. The 13.3% top rate only kicks in above $1 million. That said, California also has SDI (State Disability Insurance) that withholds 1.1% on earned income — contractors are covered under voluntary plans in some cases.
New York
New York's rate for most 1099 earners in the $50k–$120k range runs between 4.5% and 5.85% effective — not as punishing as the headline 10.9% rate suggests for everyday incomes. If you live in New York City, add NYC city tax on top of state: roughly $1,350–$3,200 more per year across these income levels, pushing quarterly payments $340–$800 higher than the table above.
Illinois
The flat 4.95% makes Illinois easy to calculate: take your federal taxable income, multiply by 4.95%. No brackets to worry about. At $80k, that's around $2,883 in state tax.
Pennsylvania
Pennsylvania's 3.07% flat rate is the lowest of any state with a broad-based income tax. The math is simple. The catch: if you work or live in Philadelphia, the city wage tax adds 3.75% (residents) on top, which changes the picture dramatically. Most of Pennsylvania isn't Philadelphia, but worth knowing.
Georgia
Georgia switched to a flat tax of 5.39% in 2024, down from a graduated system that peaked at 5.75%. The simplified rate makes calculation easy.
North Carolina
NC went flat at 4.25% in 2025, down from 4.75% the year before. Another easy one to calculate. The phased reductions continue — NC has been systematically cutting its rate and is projected to keep going.
Ohio
Ohio's progressive structure is unusual: income under $26,050 is taxed at 0%. Only what's above that threshold gets taxed. At $50k net 1099 income (with taxable income around $30,367), only about $4,317 is in the 2.75% bracket — which is why Ohio's state tax comes out so low at lower income levels.
When Quarterly Payments Are Due in 2026
The IRS wants four payments per year. Miss them and you'll owe a penalty on top of the tax itself — currently calculated at the federal short-term rate plus 3 percentage points.
| Quarter | Income Period | Due Date |
|---|---|---|
| Q1 2026 | January 1 – March 31 | April 15, 2026 |
| Q2 2026 | April 1 – May 31 | June 16, 2026 |
| Q3 2026 | June 1 – August 31 | September 15, 2026 |
| Q4 2026 | September 1 – December 31 | January 15, 2027 |
Most states follow the same schedule as the IRS, but a few have slightly different dates — check your state's tax authority to confirm.
A common mistake is thinking you need to pay exactly 25% each quarter. You don't — the IRS cares about total annual accuracy. But paying roughly equal amounts each quarter keeps you safe from the underpayment penalty. The safe harbor rule: if your total withholding and estimated payments equal at least 100% of last year's tax (110% if your AGI was above $150k), you won't owe a penalty regardless of what you owe in April.
The Easiest Way to Know Exactly What You Owe
The tables above use standard assumptions — single filer, no business deductions beyond the SE deduction, standard deduction. Your actual situation is probably different. If you're deducting a home office, health insurance premiums, or retirement contributions (SEP-IRA or Solo 401k), your taxable income and quarterly bill will be lower.
For a precise number based on your actual income and state:
- 1099 Tax Calculator — enter your income and get a full breakdown of SE tax, federal, and state
- Quarterly Estimated Tax Calculator — calculates your four quarterly payment amounts with due dates
If you're making estimated payments for the first time, the most important thing to do is just start. Even rough estimates are better than no payments, and you can true things up in April.
