When did the state of kansas disallow charitable contributions claimed on the federal return?

[CarolynM]

They haven't. In fact, they have expanded the deduction. 

Here is the language from the Kansas Department of Revenue:

For the tax years commencing on and after January 1, 2015, and ending before January 1, 2018, the Kansas itemized deduction of an individual means the following deductions from federal adjusted gross income, other than federal deductions for personal exemptions, as provided in the federal internal revenue code with the modifications specified in this section: (A) 100% of charitable contributions that qualify as charitable contributions allowable as deductions in section 170 of the federal internal revenue code;  source Kansas Itemized Deductions
