TEI has filed two letters with British Columbia's Ministry of Finance proposing changes to British Columbia's provincial sales tax and carbon tax. TEI's August 31, 2015 letter, filed with the Tax Programs Branch, proposes several changes to the provincial sales tax designed to streamline tax administration for businesses and the Ministry. TEI's September 1, 2015 letter, filed with the Tax Policy Branch, proposes several revenue-related changes to the provincial sales tax and carbon tax to be considered in conjunction with the Ministry's annual budget process. The letters build on earlier comments made to the Ministry in letters and meetings with Ministry officials.The letters were prepared under the aegis of TEI's Canadian Commodity Tax Committee, whose chair is Richard Taylor. Canadian Commodity Tax Committee member Brian Moul and Pilar Mata, of TEI's legal staff, coordinated the development of the Institute's comments.
