Travel Reimbursement Policy

when it comes to mileage reimbursement, how nonprofit usually go about doing this?
I work for a nonprofit organization and my boss I just said that I will not reimburse for the return trip of a drive if I go home. The typical policy states that reimburse for mileage from the office to the office location to location. Does this not apply to the distance I travel back to the place that was meant to go into business, even if I back home instead of the office? My argument is that because I'm business since the gas and mileage, and therefore should be reimbursed the equivalent of the distance from location to the office, regardless of the fact that the office is not where I am.
I'm not sure why your boss is not willing to reimburse travel drive to a place other than your office. If the return trip is shorter than back to the office, they are saving money. However, it is a nonprofit and I'm sure times are tough with their finances well. It's a small consolation, but you can deduct these expenses are not reimbursed for business travel on your taxes for 2009 and beyond. You have to make some mileage record keeping start and end so you can deduct on their 2009 tax to 55 cents per mile. The IRS issued the standard mileage rates used to calculate the deductible costs of operating an automobile for business, charitable, medical or moving. As of January 1, 2009, the standard mileage rates for use of a car (including vans, pickups and trucks) is 55 cents per mile for business miles driven, 24 cents per mile driven for medical or moving, and 14 cents per mile driven in service organizations charity. Good luck and bon voyage!
