Privacy
Federal estimated tax helps self-employed taxpayers pay income and self-employment tax throughout the year instead of only at filing time.
Pay-as-you-go federal tax
The IRS expects many self-employed taxpayers to pay federal income and self-employment tax during the year rather than in one lump sum at filing time.
Four estimated payments per year
Form 1040-ES schedules four quarterly payments. Each due date covers tax on income earned in that part of the year.
Based on annualized income
Quarterly amounts are planning estimates derived from your expected annual federal tax. Actual required payments can change if income shifts.
Safe harbor reduces underpayment risk
Paying enough through withholding and estimated tax by each due date can help avoid federal underpayment penalties. This calculator shows common safe harbor targets for planning.
A simplified federal model based on annualized self-employment income, optional prior-year safe harbor inputs, and Form 1040-ES planning mechanics.
Annual federal tax first
The engine estimates annual self-employment tax and federal income tax from your net self-employment income and optional other income.
Remaining tax after payments
Estimated payments you already made reduce the remaining federal tax used to suggest quarterly amounts.
Equal quarterly split
The estimated quarterly payment divides remaining estimated tax into four equal installments for planning (Form 1040-ES worksheet simplification).
Safe harbor comparison
When prior-year tax and AGI are provided, the calculator compares 90% of current-year tax with prior-year safe harbor rules and shows the lower planning target.
Known exclusions
State taxes, tax credits, underpayment penalty calculations, and uneven income timing within the year are not fully modeled.

Paying enough federal tax during the year through withholding and estimated payments can help avoid underpayment penalties.
90% of current-year tax
A common federal safe harbor is paying at least 90% of your current tax year liability through withholding and estimated payments by the due dates.
100% of prior-year tax
If prior-year tax and AGI are known, paying 100% of last year’s total tax can also satisfy safe harbor when AGI is at or below the IRS threshold ($150,000 for most filers; $75,000 married filing separately).
110% for higher prior-year AGI
When prior-year AGI exceeds the threshold, the prior-year safe harbor increases to 110% of prior-year tax.
Planning target shown
This calculator displays the lower applicable safe harbor target alongside your annual estimate. It does not calculate penalties or verify payment timing.
