AGO 1969 NO. 21 >
A person exempted from paying the first $50 of a given year's real property tax under RCW 84.36.128, who nevertheless pays this amount by reason of mistake, inadvertence or lack of knowledge, need not have claimed his exemption between February 15 and April 30 in order to set the stage for a valid refund claim under § 1 (7) of chapter 224, Laws of 1969, Ex. Sess.; instead, we would deem it to be sufficient compliance with the statute for a taxpayer to prove his eligibility for the exemption (as of the time his payment was made) when he files his application for a refund.
