关于此工具

Enter your expected income for the year, your deductions, credits and tax withheld, and last year's tax. The tool computes income tax and self-employment tax, applies the safe harbor (90% of this year's tax or 100% of last year's, 110% when last year's AGI was over $150,000) and shows the four payments.

如何计算数额

Self-employment tax is 15.3% of 92.35% of net profit (12.4% Social Security up to the wage base plus 2.9% Medicare). Half of it is deducted from income. Income tax uses the federal brackets for the year you choose, after the larger of the standard deduction and your itemized deductions.

安全港口

You avoid the underpayment penalty if you pay at least 90% of this year's tax or 100% of last year's tax (110% when last year's AGI was above $150,000, or $75,000 if married filing separately). If you expect to owe less than $1,000 after withholding, no estimated payments are needed.

应付日期

付款期限为下一年的4月15日,6月15日,9月15日和1月15日.周末或假期的日期将移动到下一个工作日.不包括州估计税收

计算示例

Single in 2026 with $90,000 of self-employment profit, no withholding, and $14,000 of tax on last year's return: self-employment tax is $12,717 and income tax $9,571, so the year's tax is $22,288. 90% of that is $20,059, but 100% of last year's tax is only $14,000, so you can pay $14,000, which is $3,500 each quarter, and still be inside the safe harbor.
