When to file and pay Kansas sales tax
The Kansas Department of Revenue will assign you a filing frequency (monthly, quarterly, or annually) after you register your business.
Kansas sales tax returns and payments are due at the same time, by the 25th of the month following the end of the filing period. This is five days later than the 20th deadline used by most other states, a common source of missed deadlines for businesses managing multi-state compliance. If the 25th falls on a weekend or holiday, the due date shifts to the next business day.

How to prepare your Kansas sales tax return
Before working on your sales tax return, collect all sales information for the tax period.
Sales transactions
You need to know your total gross sales to Kansas buyers and your taxable sales. Remember that Kansas taxes digital goods and SaaS, so subscription and software revenue must be included in your taxable sales figures.
Key reporting figures
In addition to your gross Kansas sales, filing a return requires:
- Total sales and income
- Taxable sales (Kansas uses destination-based sourcing, so the combined rate depends on the buyer's city and county)
- Non-taxable sales and exemptions
- Deductions and adjustments
- Total sales tax collected from customers during the filing period
How to complete and file a Kansas sales tax return
Kansas sales tax returns are filed electronically through the Kansas Customer Service Center and must be reported in US dollars.
Step-by-step: file a Kansas sales tax return

Late filing penalties and interest
If you miss a Kansas sales tax filing deadline, file as soon as possible. Failure to file returns and remit collected tax on time results in penalties and interest charges that increase the longer you wait.
