I need help on an PCR to exclude payments from taxable dollars up to a certain limit. For example, payments for someone living in CO are exempt from state withholding up to the first $24,000. I wanted to somehow read the CRT and compare the YTD amount to a constant in table T511K. If it is more than 24,000 then add the amount to a taxable wage type. I'm not sure how to go about this. Can someone point me in the right direction?
