About this page
Kansas rent late fee law
Kansas's residential landlord and tenant law contains no late fee provision, so it neither caps a late rent fee nor gives a grace period.
Read in full for this check: Kansas Statutes Annotated, chapter 58, article 25 (Landlords and Tenants), including the Residential Landlord and Tenant Act (K.S.A. 58-2540 to 58-2573). Official source · checked .
Before you send the late rent notice: it is a reminder letter about overdue rent and a late charge, not an eviction notice. A notice to pay rent or quit is a separate document, and Kansas has its own rules for it. Nothing on this page is legal advice.
What Kansas law says about invoice interest
Except as provided in subsection (b), creditors shall be allowed to receive interest at the rate of 10% per annum when no other rate of interest is agreed upon, for any money after it becomes due; for money lent or money due on settlement of account, from the day of liquidating the account and ascertaining the balance [...]
15% written cap does NOT apply to business or agricultural transactions (purposes other than personal/family/household) — those may carry any agreed rate.
