$4 per gallon gas prompts increase
in IRS mileage rates

I just got back from a story interview on the other side of Austin. The round trip was 47.8 miles.

So you can imagine my delight, upon returning to my office, in learning that the IRS today hiked the optional standard business mileage rate by 8 cents.

I was not, however, so pleased to discover upon closer reading of my tax news e-mails that my business travel earlier this afternoon can’t be counted under the new 58.5 cents per mile rate. The higher calculation level doesn’t kick in until July 1.

Guess I’ll be pushing off any further face-to-face interviews, where practical, until after that date!

The IRS said it made the special adjustment to the optional standard rates because of the recent gasoline price increases nationwide.

Other travel rates hiked, too: In addition to bumping the per-mile rate for business-related travel from 50.5 cents to 58.5 cents, the rate to compute medical and moving mileage also will increase on July 1 from 19 cents per mile to 27 cents per mile.

The charitable driving deduction rate for the final six months of 2008, however, will remain at 14 cents per mile. Don’t get mad at the IRS. That write-off rate is determined by law, not left to the discretion of the IRS based on fuel price fluctuations.

As I’ve said before, tell your Senators and Representative how unfair you think it is for charitable miles to be locked in at such a low reimbursement rate.

You might want to copy the table below and/or bookmark this post as a reminder of the multiple calculations you’ll have to make when computing mileage deductions on you 2008 tax return. The new rates also are detailed in Announcement 2008-63.

Remember, when you have eligible business travel, you can use the optional standard mileage rate to compute deductible costs of using your auto in lieu of
tracking actual costs. Tax Topic #510 has more details on writing off business use of a vehicle.

Tax answer to driver pleas: The IRS usually updates the mileage rates once a year, typically in the fall for the next calendar year. The 2008 figures we started the year with were issued late last November.

But some folks thought that was too long to wait and recently had asked the IRS for relief in this area.

On June 13,
the National Treasury Employees Union urged the IRS to make a midyear mileage rate adjustment because of record, and still rising, gas prices. According to the Department of Energy’s Energy Information Administration (say that three times fast!), since the 2008 reimbursement rates were announced last year, the price of a
gallon of gasoline in the U.S. has risen 31.2 percent, from $3.079 to $4.039.

 In addition, The Tax Foundation reported that Minnesota Senator Norm
Coleman made a similar request to the IRS. 

The IRS got the message.

"Rising gas prices are having a major impact on individual
Americans. Given the increase in prices, the IRS is adjusting the
standard mileage rates to better reflect the real cost of operating an
automobile," said IRS Commissioner Doug Shulman. "We want the
reimbursement rate to be fair to taxpayers."

Gasoline prices are the most significant consideration in changing the mileage rates, but the IRS notes that other things, such as vehicle depreciation, insurance and "other fixed and variable costs," also are used to determine the mileage figures.
