Record the applicable mileage only

As a general rule, the deductible mileage is the one that has been described above.

Your trips to your office and back are considered commuter miles, and they are not applicable when calculating deductible mileage for tax purposes.

The IRS considers where you live a personal choice and therefore the expense will be on you regardless of whether you live far away from the office or not.

In some companies, you will be given a mileage allowance, or there will be some other kind of arrangement if you have been given a company car.

If you have been reimbursed for your mileage by your employer, that mileage is not an allowable deduction.

Speak with your financial advisor to understand the implications of reimbursed mileage and deductible mileage to your overall salary.

Calculate your total mileage at the end of the year

To compute the total mileage deduction for the year, or apply the total number of miles driven through the year by the rate applicable for each of the above categories including business miles, charity miles, medical purpose miles and Moving miles.

Example: If you drove 1,000 miles for charity purposes, 1,000 miles for business purposes, 500 miles for medical reasons and 200 miles for moving purposes, your total mileage for the year will be 2700 miles.

If you are calculating the deductible miles for 2024, then the following will apply:

Charity1,00014 cents140
Business1,00067 cents670

Safely store the records

The IRS recommends that you keep all your records for a period of between 3 to 7 years.

Typically, this is the window within which the IRS might conduct an audit, and you will, therefore, need sufficient records to substantiate mileage claims.

Besides, you will also need to contact your internal audit to ensure that you have been claiming the right amount of mileage deductions.
