Hi. In the past years I (the owner, LLC) kept track of how many miles were used for business. How entered in the past? At beginning of the year starting odometer miles from each car is recorded and at the ending of the year, the same is recorded. Within Turbo Tax, the difference w/in the start & finish = miles for the year. I then declare what portion of the total miles for the year is business and how much is personal. Enter this into Turbo Tax. Done for the year. Only a detailed excel spreadsheet reflects the date, job # (if any), starting odometer numbers, ending odometer, formula setup to calculate the amount of miles for the trip, amount of miles is then calculated automatically by a formula: miles x IRS rate for business. NOW a client wants to reimburse the incurred mileage for all business related trips. How do I enter this into QB online? The excel spreadsheet is easy to calculate BUT the billing and then reimbursement from client for mileage is a new type of transaction for me. It also affects the bank balance when reconciling. In summary: 1) how do bill the client for mileage? 2)a. Never before entered QB online mileage tracking per job nor kept a specific receipt for the "portion for business". keep track of receipts since the payment for gas is for personal & business. 3)a Never declared it this way w/QB.
