Mass removal of a sales tax on client accounts - anyone know how to do this? Delete tax from table?

SOLVED

One of the counties we serve had a small stadium sales tax for several years which will now end. To go through maintain customer for every single one at a time and remove this seems tedious and I can't imagine this is how BW handles it. I do not see this under Customers, Global Customer Change... So, I am wondering if I just go into Maintain Tax Tables under A/R and delete this tax if that will remove it from all these accounts? However, if I do so, I wonder how it would then affect any reporting I do from previous years months stored in BW and/or my YTD or my G/L reports, etc. etc.
