What is the penalty for late payment of income taxes?

The penalty for late payment of income taxes in Kansas is calculated at 1% per month on the unpaid amount, subject to a maximum penalty of 24%. Additionally, interest accrues on the unpaid balance at a variable rate determined by state law. It is important to note that penalties and interest are only imposed on the amount of tax due after any allowable credits and payments have been applied. To avoid penalties, it is recommended to pay income taxes in full by the due date or to request an extension, which grants an additional six months to file but does not extend the deadline for payment. For more detailed information on penalties and payment options, refer to the Kansas Department of Revenue's website or contact their customer service.
