Frequently Asked Questions
Who needs to pay quarterly estimated taxes?
Any independent contractor, freelancer, or gig worker who expects to owe $1,000 or more in federal taxes for the year must make quarterly estimated payments to avoid IRS underpayment penalties.
How does the calculator determine my payment amount?
It applies the 15.3% self-employment tax on your net earnings plus your estimated federal income tax bracket, then divides by four quarters — adjusting for income you enter throughout the year.
