Higher Standard Mileage Allowance

In case you missed the news, the IRS standard mileage has increased (as of July 1, 2011) to 55.5 cents per mile.  From the beginning of the year until June 30, the amount was 51 cents per mile (I think that is the few times I can remember where it was actually an even amount).  Maybe to be humorous, whoever decided the rate likes to use "half cents".  Anyway, the timing of the increase was fairly sweet as it came just as the price of gas was decreasing so it can be profitable (?) for those that do a lot of driving between jobs.  Just remember that regular commuting is not allowed as a deducting mileage.  Also, unless the price of gas takes a hike, the mileage allowance as of the first of next year may be reduced from the current rate.
