Kansas sales tax filing rules
Good to know
Kansas returns are due the 25th of the month following the reporting period.
Filing Kansas sales tax late
Kansas charges a late-filing and late-payment penalty plus interest on any unpaid tax, and most states apply a minimum penalty even on a zero return. File on time — even a return with no tax due must be filed. Confirm current penalty amounts with the Kansas Department of Revenue.
