That's because, as of July 1, 2008, the tax deduction for business mileage has been increased to $0.58 per mile. This increase means you really need to keep the most accurate vehicle mileage log possible for two reasons:

Since you're getting a larger tax deduction for business miles, it just makes sense to record 100% of your business mileage if possible. If you forget to record even 100 business miles, you'll be paying tax on an additional $58 of income.00!

Many accountants believe that with an increase like this, the IRS will be scrutinizing mileage deductions even closer now. You'll want to maintain the most accurate records possible in the event that the IRS questions you about your deduction.

Most folks cringe when you even mention the term "mileage log" to them. If you have ever had to keep track of your vehicle's mileage, then you know how cumbersome a manual mileage log can be ...

First off, you need to find your Daytimer or a scrap of paper and then record the beginning mileage you're starting with plus the purpose of your business trip and the date. Then at the end of your trip you need to remember to record the ending mileage. Then you need to calculate the actual miles driven.

Then you need to input your raw data into a spreadsheet and go through all that's involved with that.

It can (and does!) get to be a real horror story! Keeping track of a manual mileage log is definitely no fun at all. Anyone who needs to track their mileage on a regular basis knows just what I mean, right!

Thankfully, modern digital technology provides a simple solution to this chore in the form of a digital mileage logger. These relatively new products will automate the process of maintaining your mileage log and make it a snap to generate the documentation you need for IRS reporting or any other mileage log requirement.

And it's so easy to do. No more scrambling around for a piece of paper or your Daytimer to record your mileage. A digital mileage logger simply plugs into your car's cigarette lighter and then at the beginning of your trip it starts recording your mileage, using GPS (Global Positioning System) technology to calculate your vehicle's position and thereby its mileage.

At the end of your trip, the tool sends your final mileage to the website associated with it where you'll be able to login and add any details necessary or format and download your reports.

And the units are so small that it's easy to move them from vehicle to vehicle in case you use more than one for your business trips.

Anyone with a significant amount of mileage to track really needs to consider automating their mileage log.
