FAQ
Kansas Property Tax Appeal Questions
Can my Kansas assessment increase if I appeal?
No. Kansas law protects homeowners from assessment increases during the informal appeal process. At the formal level, the Board of Tax Appeals focuses only on the issues you raise.
How does the 11.5% ratio work in Kansas?
If your home's fair market value is $300,000, the assessed value is $34,500 (11.5%). Your tax bill is this assessed value multiplied by your local mill levy.
How often does Kansas reassess?
Kansas reappraises all property annually. The county appraiser determines market value as of January 1 each year based on sales data and property characteristics.
