Earlier quoted context omitted.
Where can you file for sales tax reimbursement? Essentially all online resale sites (eBay, Reverb, etc.) are charging sales tax on secondhand goods. So if I buy something, then sell it later, that first purchase should be considered a "resale" purchase, right?
If you're a registered business with a tax ID number, you can deduct sales taxes paid on business inputs (supply) on your income taxes, whether personal or business.
However, you can only deduct items so acquired for business purposes, not for personal purposes.
