GSA has increased the mileage reimbursement rates for federal employees who use privately owned vehicles while on official travel. The rates for the use of these modes of transportation, effective January 1, 2011, are as follows:
Privately Owned Vehicle Reimbursement Rates:
2011 Rates 2010 in brackets
– Airplane ……… $1.29 per mile [$1.29, no change]
Automobile Rates… $0.51 cents per mile [0.505, change 1/2 cent]
Motorcycle Privately Owned Rate … $0.48 cents per mile [$0.47, 0.01 cent change]
Also from GSA: Airplane nautical miles (NMs) should be converted into statute miles (SMs) or regular miles when submitting a voucher using the formula (1 NM equals 1.15077945 SMs). You can also use the link to BoatSafe.com (a non-government website) to assist you in converting NMs to SMs or SMs to NMs.
