Calculate
Note: This is a tool to help you calculate your total amount due if you have filed or paid late. It has been designed for initial late filings or payments and may not be used to calculate a balance if you are using a partial pay plan, have previously made payments to the department for the same tax period, or have filed for and received an extension of time to file. Make sure you select the the appropriate tax type for your payment. If you are paying sales or withholding tax late, remember NOT to include a timely compensation deduction. If you have questions about tax types not insluded in the calculator, Please refer to your forms page for instructions or email dormail@dor.mo.gov
