1099 Tax Calculator With Deductions
Business expenses reduce the net earnings used by this calculator. Common deductible costs can include qualifying software, equipment, business mileage, and home-office expenses. Whether an expense is deductible depends on IRS rules and your circumstances.
How Much Should I Set Aside?
There is no single percentage that is correct for every 1099 worker. Your federal income tax depends on your overall taxable income and filing situation, while self-employment tax is calculated separately. Use the estimate above as a planning figure rather than a tax return calculation.
Quarterly Estimated Taxes
Individuals generally need estimated tax payments when they expect to owe at least $1,000 when filing, subject to IRS rules and exceptions. For tax year 2026, the standard estimated-payment dates are April 15, June 15, September 15, 2026, and January 15, 2027.
