Ok. First we need to know is the business a proprietorship or partnership, or a corporation? Are you the owner of the business?
If yes to #2, and yes to either a) or b) above, then why are you tracking this? This is looked after on your personal taxes on the Statement of Business Activities that you send with your regular T1. Unless your Prop or Part are going like gangbusters, then why not incorporate?
If #2 is yes and yes to c) above, how do you pay yourself? Cut a cheque? How do you reimburse yourself for purchases made for the business cash out of your pocket? Total up receipts and cut another cheque? Suggestion: do a Petty Cash report and include your KMs and the $.36/km on the petty cash report. If you like, I can send a sample Excel spreadsheet for P/C.
You really CAN'T get QB to track that for you. Someplace you have to input the 36 cents per km car expense.
BTW, reimbursement for KMs is NOT TAX FREE. It is a taxable benefit. However, if you instead submit your gas receipts, that is a reimbursment of expenses....
Check with your accountant.... please.
