As tax time is upon us, I was wanting to get a Business Number(Ontario) so that I could eliminate giving out the SIN multiple times. I have tried 3 times on the online registration form, and all it does is summarize my info at the end, but not give me a business number. It asks about govt. programs you want to register for, such as payroll, employees and CPP/EI, GST etc. but none of these apply to my sole proprietorship and GST-exempt business, so I did not check those boxes. At the end it summarizes my business name/address/sole proprietorship etc but won't give me a number. Why not???? Feedback please from anyone who did the online Business Number registration in Ontario. Thanks.
