This is a tool to help calculate late file and late pay penalties and interest on a late filed Individual Income tax return. It cannot be used to compute the penalty for underpayment of estimated tax.
Only use the calculator when you're sending your return and payment together. See Disclaimer.
- Late filing and late payment penalties and interest will continue to accrue until we receive your return and payment.
- If we receive your payment after the date you specify in this calculator, you may receive a bill for additional penalties and interest owed.
- To calculate the Underpayment of Estimated Tax - M-2210 Penalty, for the current year, please go to M-2210.
