How much self-employment tax do I pay on 1099 income?

Self-employment tax is 15.3% on 92.35% of your net self-employment income. This breaks down to 12.4% for Social Security (on earnings up to $184,500 in 2026) and 2.9% for Medicare. An additional 0.9% Medicare tax applies to earnings above $200,000 (single) or $250,000 (married filing jointly). On $80,000 of 1099 income, SE tax is approximately $11,294.

What deductions can I take as a 1099 contractor?

Common deductions include: 50% of self-employment tax (automatic above-the-line deduction), home office ($5/sqft simplified method up to 300 sqft), business mileage ($0.70/mile in 2026), health insurance premiums, retirement contributions (SEP-IRA up to 25% of net earnings or Solo 401k), equipment and software, professional services, and other ordinary and necessary business expenses.

When are quarterly estimated tax payments due?

Quarterly estimated payments are due April 15, June 15, September 15, and January 15 of the following year. If you expect to owe $1,000 or more in tax, you must make quarterly payments or face underpayment penalties. The safe harbor rule means you avoid penalties by paying at least 90% of current year tax or 100% of prior year tax (110% if AGI exceeds $150,000).

How much more tax do 1099 contractors pay compared to W-2 employees?

1099 contractors pay approximately 7.65% more in taxes than W-2 employees at the same income level. This is because contractors pay both the employer and employee share of FICA taxes (15.3% total vs 7.65% for W-2 employees). On $80,000 of income, a 1099 worker pays roughly $5,600 more in total taxes than a W-2 employee. However, 1099 workers can deduct 50% of SE tax and have access to business deductions that W-2 employees cannot claim.

How to Use This Calculator

Tab "Total Tax Bill"

Enter your 1099 gross income, filing status, and state. The calculator computes self-employment tax (15.3% on 92.35% of net earnings), federal income tax using 2026 brackets, and an approximate state tax. It also shows how much more you pay compared to a W-2 employee at the same income level. Expand "More options" to add W-2 income if you have a day job alongside freelancing.

Tab "Deductions"

Enter your business expenses to see how they reduce your tax bill. The calculator automatically applies the 50% SE tax above-the-line deduction plus any business deductions you enter: home office (simplified $5/sqft method), business mileage ($0.70/mile), health insurance premiums, retirement contributions, equipment, professional services, and other expenses. The result shows your effective rate before and after deductions and the total tax savings.

Tab "Quarterly Payments"

See your quarterly estimated tax payment schedule with due dates. Enter how much you have already paid this year and the calculator splits the remaining balance into equal quarterly payments. It warns you if you are at risk of underpayment penalties based on safe harbor rules.

The Formulas

Self-Employment Tax:
Net SE income = 1099 gross income − business deductions
SE tax base = Net SE income × 92.35%
Social Security = 12.4% × min(SE tax base, $184,500)
Medicare = 2.9% × SE tax base
Additional Medicare = 0.9% × max(0, SE tax base − $200,000)
Total SE tax = Social Security + Medicare + Additional Medicare

Above-the-Line SE Tax Deduction:
Deduction = 50% × Total SE tax
This reduces your adjusted gross income (AGI) before calculating income tax.

Federal Income Tax:
Taxable income = Total income − Standard deduction − 50% SE tax deduction
Standard deduction: $15,750 single · $31,500 MFJ · $23,500 HoH
Tax = Sum of (taxable income in each bracket × bracket rate)
Brackets: 10%, 12%, 22%, 24%, 32%, 35%, 37%

Common Business Deductions:
Home office = min(sqft, 300) × $5/sqft (simplified method)
Mileage = business miles × $0.70 (2026 IRS standard rate)
Health insurance, retirement, equipment, professional services = actual amounts

Quarterly Estimated Payments:
Per quarter = (Total annual tax − Already paid) ÷ 4
Safe harbor: Pay ≥ 90% of current year tax OR 100% of prior year tax (110% if AGI > $150K)

Example

$80,000 1099 Income — Single, No State Tax, No Deductions

1099 gross income$80,000

SE tax base (92.35%)$73,880

Social Security (12.4%)$9,161

Medicare (2.9%)$2,143

Total SE tax$11,304

50% SE tax deduction$5,652

Federal income tax$7,262

Total tax bill$18,566

Effective tax rate23.2%

After-tax income$61,434

On $80,000 of 1099 income (single, no state tax), you pay $11,304 in self-employment tax and $7,262 in federal income tax for a total of $18,566. A W-2 employee earning $80,000 would pay approximately $12,992 in total taxes — you pay roughly $5,574 more due to the employer share of FICA. Adding $10,000 in business deductions (home office, mileage, equipment) would save approximately $2,800 in taxes.

Frequently Asked Questions

Do I have to pay self-employment tax on all my 1099 income?▼

Yes, if your net self-employment earnings exceed $400 in a year, you owe self-employment tax. The tax applies to 92.35% of your net earnings (after business deductions). The 92.35% factor accounts for the fact that employers deduct FICA from gross wages, so self-employed individuals get a similar adjustment. You cannot avoid SE tax, but you can reduce the base by claiming legitimate business deductions.

What happens if I do not make quarterly estimated payments?▼

If you owe $1,000 or more when you file your return and have not made sufficient quarterly payments, the IRS charges an underpayment penalty. The penalty is essentially interest on the amount you should have paid by each quarterly deadline. For 2026, the rate is the federal short-term rate plus 3 percentage points, compounded daily. You can avoid the penalty by meeting the safe harbor: pay at least 90% of your current year tax or 100% of your prior year tax liability (110% if your AGI exceeds $150,000).

Can I deduct health insurance premiums as a self-employed person?▼

Yes. Self-employed individuals can deduct 100% of health, dental, and long-term care insurance premiums for themselves, their spouse, and dependents. This is an above-the-line deduction (you do not need to itemize). However, the deduction cannot exceed your net self-employment income, and it does not reduce your self-employment tax base — it only reduces your income tax.

What is the difference between SEP-IRA and Solo 401(k) for self-employed?▼

Both allow significant retirement contributions that reduce your taxable income. A SEP-IRA lets you contribute up to 25% of net self-employment earnings (max $70,000 for 2026). A Solo 401(k) allows an employee contribution of up to $24,500 ($32,500 if 50+) plus an employer contribution of up to 25% of net earnings. For most self-employed individuals earning under $200,000, the Solo 401(k) allows higher total contributions because of the employee deferral component.

How do I report 1099 income if I also have a W-2 job?▼

You report 1099 income on Schedule C (Profit or Loss From Business) and calculate SE tax on Schedule SE. Your W-2 income is reported normally on your 1040. Both incomes are combined for federal income tax purposes, which may push you into a higher tax bracket. However, the Social Security portion of SE tax takes into account W-2 wages already subject to Social Security — if your W-2 wages already exceed the $184,500 cap, you will not owe the 12.4% SS portion of SE tax.
