There are two types of ways to calculate the mileage deduction. One is the Actual Expense method (AE), and the other is the Standard Mileage Rates (SMR).

With the Actual Expense method, you need to keep track of all the expenses of running the car. You will then need to sift through the documentation to get the expenses that you incurred when running errands for the business.

The Standard Mileage Rates method is prescribed by the Internal Revenue Service (IRS) which puts into account factors such as wear and tear, gasoline price etc. to come up with a standard rate.

The rate changes now and then. As of 2018, the following are the prevailing rates:

Rate per mileFor Which Purpose?
54.5 centsBusiness drives
18 centsMedical and moving drives
14 centsCharity drives

According to IRS, every taxpayer should have records of miles driven for business for the last five years. Below are the rates for the previous three years.

What are Business Drives?

  • Errands/supplies – Any business related around that you take is considered a business drive. Examples of such a business drive include visiting the post office, going to the bank, getting supplies from the local store etc. Most self-employment business owners forget these little trips, but they can add up to a huge deduction at the end of the year.
  • Business meals and entertainment – If you drive to meet a vendor or a client, the IRS consider this a business drive. Examples of such a drive include meeting a client over lunch, getting coffee with a vendor, entertaining your business colleagues during the happy hour etc.
  • Airport/travel – When you make business travel to and from the airport, the IRS considers this our work trip and hence it is an allowable deduction.
  • Odd jobs – you have a side job such as babysitting, lawn mowing, and pet care you can deduct the miles from your taxes.
  • Customer visits – Driving from your office to a client site to meet a customer or client qualifies for mileage deduction.
  • Temporary job sites – If you drive from home to any temporary job, you qualify to log the mileage for tax deduction purposes. The IRS considers any job that lasts less than one year is temporary.
  • Job seeking – if you are driving to and from home looking for a job in the same industry as your previous job, then you can deduct the mileage from your taxes.

Can You Deduct Commuting to Work Mileage?

As a rule, you cannot deduct your mileage to and from work. According to the IRS, the first trip from your house and the last trip back to your home are not deductible mileage.

The rule holds even if you travel from very far to your office. Where are you living is considered a personal choice and hence a personal expense.

If you work when you’re commuting, it will still be considered as commute, and it is not an allowable deduction. Include listening work podcasts, making business calls, replying to emails etc.

How to Use a Home Office to Beat the Commuting Rule

One way to get around the IRS commuting rule is to have a home office from where you can commute to your other business locations. Such a commute is an allowable deduction according to the IRS.

For your home office to qualify as your primary place of business, you have to prove to the IRS that you earn a larger percentage of your income from there and you also perform your management and administrative cost from the home office.

How to Claim Mileage on Taxes

If you use the standard mileage rate for your mileage deductions, you need to multiply your total number of business drives by the applicable rate for the year.

You can add the business packing and tools to that amount and then deduct it on your file returns form.

Mileage deduction is input on the Schedule C line 9 of the returns file.

Apart from demanding the reading of your odometer when you started to drive for business, the IRS will also want you to produce proof that indeed you drove for work.

For a W-2 employee, there are scenarios where you can write off you are business miles.

However, there are a few red flags that will put you in trouble with the IRS including;

  • filing a round number such as 10,000 miles
  • claiming 100% of all your mileage for business
