Question: tax exemption certificate (in Ontario). ?
There, I have a small print shop. One of my clients (performing arts business) asked me to print brochures for her and told me that she did not have to pay the PST,once she supplied the tax exemption certificate (in Ontario) or filled out the retail tax exemption form (in Ontario). Is that true? Please help! Thanks
