Can I claim the difference between the IRS standard and my actual corporate travel reimbursement? I've been doing a good amount of business travel lately. My employer reimburses mileage and provides a per diem. However, both those amounts are below the standard IRS rates. For instance, the IRS mileage deduction is $0.485 per mile, while my company reimburses $0.405 cents per mile. The IRS per diem for the region I travel to is $44 / day while my company pays $35 / day. When I file my 2007 taxes, can I claim the difference between the allowable and actual reimbursements and an unreimbursed business expense? I travelled 2,000 miles for business, so was reimbursed $810. At the IRS mileage rate, that would have been $970. Can I claim the $160 as an unreimbursed business expense? Is the scenario different for mileage and the per diem? I'd prefer answers from folks who have actually faced the situation (or tax specialists) rather than speculation. Many thanks!

Mileage Reimbursement for foriegn countries? We are a government contractor and we have employees in Germany and Korea. When they use their personal vehicles for business, we have been reimbursing them at the standard IRS rate ($.485/mile in 2007). Is there a chart for foriegn countries? The gas is Germany and Korea is almost double the cost in the US. Thanks
