How much to set aside for 1099 taxes
A practical set-aside framework for freelancers and gig workers who want to avoid April surprises.
Start with gross vs net income
A useful set-aside starts with net income, not just gross deposits. A seller with heavy materials and shipping costs may need a different percentage than a consultant with very low expenses.
Enter gross income and business expenses separately so the calculator can show net self-employment income before estimating tax.
Use tax brackets and SE tax together
Self-employment tax and federal income tax are separate layers. SE tax can apply even when income tax is low, while income tax depends on filing status, deductions, credits, and other household income.
A flat rule of thumb can be too high for some users and too low for others. The calculator uses brackets and SE tax rates so the set-aside responds to the actual inputs.
Adjust the set-aside after each deadline
The right percentage can change after each payment deadline. If the first half of the year is slow and the second half is strong, a single early-year estimate may understate later payments.
Re-run the estimate after major invoices, marketplace sales spikes, a new W-2 job, or a change in withholding.
The guide explains the rule. The calculator shows how it changes your next quarterly payment.
