This calculator only computes late filing/late payment penalties and interest due when the balance of tax due is sent with the late filed return. If other late payments were made, the calculator cannot properly calculate the balance of penalty and interest currently due. If you require assistance, please contact us.
This calculator cannot be used to compute the penalty for underpayment of estimated tax by a corporation (Form CT-222) or the penalty for underpayment of estimated income tax (Form IT-2105.9) by individuals and fiduciaries. This calculator will not compute shareholder penalties for late filing of a Sub Chapter S Return (H2 Penalties). This calculator will not compute the penalty for failure to provide shareholder information. For additional information see Form CT-3-S-I. To obtain the applicable interest rates used in computing these penalties, see our interest rate information.
Late filing/late payment penalties and interest accrue until the date the Department receives your late tax return and payment. When filling in the "estimated date the return and payment will be received" field in the calculator, please allow sufficient time for the Department to receive the return and payment. If you are mailing a return and payment or giving them to a private delivery service which qualifies under section 7502 of the Internal Revenue Code, the exact amount of late filing/late payment penalties and interest owed will be based on the date they are actually received by the Department, not the date they are postmarked or given for delivery to the qualifying private delivery service. If you are filing a return/making a payment electronically, the exact amount of late filing/late payment penalties and interest owed will be based on the date the accepted return and payment were transmitted.
Please be aware that you may receive a bill for additional late filing/late payment penalties and interest owed if the date you specify in this calculator is earlier than the date on which the Department receives your late return and payment. Also, please be aware that this calculator only computes penalties for late filing and late payment. Depending upon the facts of your case, additional penalties may be due pursuant to law.
Interest is always due on the underpayment or late payment of tax and is computed at the applicable rate determined pursuant to the New York State Tax Law. It is compounded daily from the due date of the return to the date the tax is paid.
