The Freelancer’s Guide to 1099 Taxes
Gig Economy · Sole Proprietor · Quarterly Taxes
If you drive for Uber, deliver for DoorDash, or run your own freelance business, your taxes are vastly different from a standard employee's. Because you don't have an employer withholding taxes from your paycheck, you are fully responsible for the dreaded 15.3% Self-Employment Tax.
Why is SE Tax So High?
When you work a W-2 job, the IRS requires your employer to pay 7.65% in payroll taxes on your behalf, and they deduct the other 7.65% directly from your paycheck.
When you are a freelancer or contractor, the IRS views you as both the employer and the employee. This means you must pay the full 15.3% burden yourself. This catches many new freelancers off guard at tax time, leading to massive, unexpected tax bills and underpayment penalties.
How the Calculation Actually Works
You do not pay SE tax on your Gross Income. You pay it on your Net Profit (which is your income after all business deductions, like the 72.5¢/mile standard mileage rate in 2026).
Even then, the IRS applies a special multiplier. You only pay the 15.3% tax on 92.35% of your Net Profit.
(Net Profit × 0.9235) × 0.153 = Total SE Tax
The "Above-The-Line" Deduction
To help ease the burden of paying both sides of the tax, the IRS allows you to deduct exactly 50% of your Self-Employment tax from your adjusted gross income. You do not need to itemize deductions to claim this! It is an automatic adjustment that lowers your regular income tax burden.
Quarterly Estimated Taxes (Form 1040-ES)
The US tax system is "pay-as-you-go". Because you don't have withholding, if you expect to owe more than $1,000 in taxes for the year, you are legally required to make quarterly estimated payments to the IRS. If you wait until April to pay your entire tax bill, the IRS will hit you with underpayment penalties and interest.
Our calculator automatically divides your total estimated tax liability by 4, giving you the exact amount you should send to the IRS every quarter (April 15, June 15, September 15, and January 15).
How to Legally Reduce Your Tax Burden
The absolute best way to lower your SE tax is to track every single legitimate business expense. Every dollar you claim in expenses reduces your Net Profit, which reduces both your SE tax and your Income tax.
- Mileage: If you use your personal car for Uber, DoorDash, or driving to clients, track your miles. At 72.5 cents per mile in 2026, this is a massive deduction.
- Home Office: If you use a dedicated part of your home exclusively for business, you can deduct a portion of your rent or mortgage. (Check out our Rent Calculator if you're planning a move).
- Retirement: Opening a SEP-IRA or Solo 401(k) allows you to shelter tens of thousands of dollars from income tax (though it does not reduce SE tax).
The S-Corp Strategy
Once your freelance business is netting over $80,000 to $100,000 a year, you should consult a CPA about electing S-Corporation status. As an S-Corp, you can pay yourself a "reasonable salary" (which is subject to the 15.3% SE tax) and take the rest of the profit as an "owner's draw" or distribution (which is exempt from SE tax, saving you thousands of dollars).
