Four equal payments of $3,009 cover the federal tax on this income. You generally avoid the underpayment penalty if you owe less than $1,000 after withholding, or if you pay at least 90% of this year’s tax or 100% of last year’s (110% if last year’s AGI was over $150,000).

No state selected, so state income tax is not included. Choose your state to add an estimate.

Not included: credits such as the EITC or child tax credit, the self-employed health insurance and retirement plan deductions (they lower income tax but not self-employment tax), and local taxes.
