Valuation limits
Oklahoma Constitution Article X, §8B limits annual increases in fair cash value for locally assessed real property to 5%; homestead and agricultural property are limited to 3%. The limits generally do not apply after a title transfer, change or conveyance, or to value added by improvements. The separate senior valuation limitation is governed by Article X, §8C and OTC Form 994.
