About Quarterly Estimated Taxes
Who needs to pay: Generally, you must make estimated tax payments if you expect to owe at least $1,000 in tax after subtracting withholding and credits, and your withholding will be less than 90% of current year taxes or 100% of prior year taxes (110% if AGI was over $150,000).
Safe harbor rules: You can avoid underpayment penalties by paying either 90% of current year taxes OR 100% of prior year taxes (110% if prior year AGI exceeded $150,000), whichever is less.
State quarterlies: Many states also require quarterly estimated payments. Due dates and rules vary by state. This calculator includes state taxes in your estimate, but check your state's requirements for specific rules.
Underpayment penalties: If you don't pay enough by each quarterly deadline, the IRS charges interest on the underpayment. Making equal quarterly payments helps avoid this.
This is an estimate for educational purposes only and is not tax advice. Your actual quarterly payments may differ based on deductions, credits, and other factors.
