What goes into a 1099 tax bill

As a contractor you pay two federal taxes. Self-employment tax covers Social Security and Medicare at 15.3%. Income tax uses the normal brackets, from 10% to 37%.

Both are charged on profit, not on what clients pay you. That's why deductions matter so much. Every $100 of real business cost saves most freelancers about $23 to $30 in federal tax.

Mileage changed halfway through 2026

The IRS raised the standard mileage rate on July 1 because of fuel prices. Miles from January to June are worth 72.5¢. Miles from July to December are worth 76¢. That's why the calculator asks for two numbers. Your mileage log needs dates for this reason too.

The simple home office rule

If part of your home is used only for work, you can claim $5 per square foot, up to 300 square feet. That's a $1,500 deduction at most, with no receipts for rent or power needed. A spare room you also sleep in doesn't count.

Didn't get a 1099? You still owe

From 2026, clients only have to send a 1099-NEC once they pay you $2,000 or more. Payment apps only send a 1099-K past $20,000 and 200 payments. Income under those lines is still taxable, and the IRS expects you to report it.

Profit after all deductions: $46,060
W-2 pay: $0
Self-employment tax: $6,508
Half of that tax, deducted: $3,254
Standard deduction: $16,100
Business income deduction: $5,341
Income you pay income tax on: $21,365
Income tax: $2,316
Total federal tax: $8,824

Not included: state and city tax, tax credits like the child tax credit, and deductions for health insurance or retirement accounts. Each of those can lower your bill.
