https://www.taxtmi.com/caselaws?id=162296 A sales tax exemption certificate issued under an incentive scheme cannot be retrospectively modified to the detriment of an assessee after the exemption period has expired and the benefit has been fully acted upon. Incentive provisions in taxing statutes must be construed liberally, and a completed exemption that has been relied on during the eligible period cannot be withdrawn or altered later; only timely correction of factual errors within the currency of the benefit may be permissible.
