Form K-40V is the 2024 Kansas Individual Income Tax Payment Voucher. It identifies the taxpayer and payment amount and includes boxes for amended and extension payments.
Who files this form
The 2024 Kansas K-40V is a payment voucher for Kansas individual income tax payments by check or money order. The form includes directions for sending payment with your return, after you have mailed your return, or after filing electronically without paying electronically.
When it's due
- 2024 tax year: Pay on or before April 15, 2025. Payments made after that date are subject to penalty and interest.
- An extension gives you more time to file, not more time to pay.
- The form states that when a due date falls on a Saturday, Sunday, or legal holiday, returns and payments are due the next regular work day.
What you'll need
To complete the voucher and pay by mail, have:
- The K-40V voucher. Do not submit a photocopy.
- Your name, mailing address, Social Security number, daytime phone number, and payment amount.
- Your spouse’s name and Social Security number if filing jointly.
- A check or money order for the full tax due, payable to Kansas Income Tax. Write your Social Security number or numbers on it.
Use black ink and print the first four letters of each applicable last name in UPPER CASE in the spaces provided.
How to file
Pay by mail: Complete the voucher and mark the appropriate box if your name or address changed or you are making an extension payment. If sending payment with your return, place the voucher and payment loosely in the envelope. Do not attach them to your return or to each other.
Check the mailing address: The form prints two different addresses. Its instruction paragraph says that if you already mailed your return, or filed electronically without paying electronically, mail the voucher and payment to:
Kansas Income Tax
Kansas Department of Revenue
PO Box 750260
Topeka KS 66699-0260
The bottom of the voucher instead says to mail to:
Kansas Department of Revenue
PO Box 3506
Topeka KS 66625-3506
For help confirming which address to use, contact the department at 785-368-8222.
Pay electronically: Visit www.kansas.gov/payment-portal/, or visit ksrevenue.gov and log in to the Kansas Customer Service Center.
Common mistakes

- Forgetting to mark the “Name or Address Change” box when that information changed since last year.
- Attaching the voucher or payment to the return or to each other instead of placing them loosely in the envelope.
