This free 1099 tax calculator estimates how much a freelancer or self-employed person should set aside for federal taxes each quarter — combining income tax, the 15.3% self-employment tax, and a simplified QBI deduction — so you're not blindsided at tax time. It is an informational planning aid, not tax advice.
How much should I set aside for 1099 taxes?
A common rule of thumb for self-employed people is to set aside roughly 25–30% of net income for federal taxes, because you owe both income tax and the 15.3% self-employment tax. This calculator gives you a more exact figure from your actual numbers. It is a planning estimate — confirm with a tax professional.
When are quarterly estimated taxes due?
Federal estimated taxes are generally due four times a year (mid-April, mid-June, mid-September, and mid-January of the following year). This tool estimates the amount for each payment; check current IRS dates for the exact deadlines.
Does this replace a tax professional?
No. It's an informational planning aid to help you set money aside and avoid surprises. For advice specific to your situation, consult a qualified tax professional.
