However, how to calculate mileage taxes in 2022 is a basic piece of information every self-employed and small business owner should know. When it comes to calculating mileage for taxes, you basically have two types. These two types include the standard mileage rate and the actual expense method.

However, before choosing a business mileage deduction calculation method, especially in 2022, It’s important that you first consider calculating your deduction with both. This way, you will be able to determine which method gets you the greater tax deduction.

Furthermore, regardless of which method you choose to use, it’s important to keep accurate track of the record that basically backs up the mileage deductions for your business. In order to do this effectively, you can keep a log in your vehicle for organized bookkeeping. This is because the more evidence and backup files you possess, the better for your business.

How to Calculate the Standard Mileage Tax Rate in 2022

The standard mileage rate is one of the methods of the mileage tax deduction. This method of mileage rate is easier to use than the actual expense method. This is because if you use this method, you can typically claim a standard amount per mile driven. Follow these simple steps to calculate the standard method of mileage deductions for taxes in 2022. The steps include;

  • Properly check if you can really use the standard mileage rate.
  • Then, get to be familiar with the mileage deduction rates
  • Do a multiplication of the business miles driven by the IRS current rate.

According to the IRS, these are the examples of situations you should avoid in order to use the standard mileage rate. If you do any of the following, then this method is not for you. They include:

  • If you lease your car, you must use the method for the entire lease period.

Firstly, if you want to use the actual expense method, keep track of what it costs to operate your car. This is because a lot of people forget that this is typically the basis for this method. And, from these records you keep, you can typically record what part of the general expenses applies to business use.

Again, note that you won’t be able to use this method if you previously used the standard mileage rate on a leased car. For how to calculate the actual expense method, include the following expenses:

  • Gas
  • Oil
  • Repairs
  • Tires
  • Insurance
  • Registration fees
  • Licenses
  • Depreciation
  • Lease payments

It’s also important that you record exactly what you spent on the above expenses, including the date and a description of the costs. The formula and steps for how to calculate the actual expense method of deductions are below. They include;

  • Find out the exact percentage of your car you use for business purposes. You can get the results by dividing your business miles driven by your total annual miles.
  • Then, lastly, you just need to multiply your business use percentage by your total car expenses.

Self-Employed Mileage Deduction

You can say that the self-employed are mostly the beneficiaries of the mileage deductions of taxes. This is because they claim up to a 56-cent deduction per business mile driven. However, in recent times, the government keeps tightening the rules for mileage deductions.

Also, starting in 2022, the tax reform laws will also keep narrowing the mileage tax deduction for moving expenses. This is why you can now only claim this for active-duty military members who are relocating because of new orders. Most people can use a mileage deduction because they are typically designed for it. They include;

  • Business mileage for the self-employed
  • Mileage related to medical appointments
  • Mileage incurred while volunteering for a nonprofit.

All I mentioned above are categories that automatically qualify for mileage deductions as self-employed. After qualification, then, what next? Here are the important details you need to know about the mileage deductions.

Mileage for self-employed workers isn’t subject to any threshold requirements. In other words, all miles are deductible regardless of how much a person drives for work. Now, if a person drives for both business and personal purposes, only miles that are typically driven for business will be deducted as long as it is from their principal place of business.

Self-employed individuals should claim their mileage deduction on the Schedule C tax form, and not on the Schedule A form for itemized deductions. Meanwhile, it’s best as a self-employed business owner to be certain of the type of mileage or actual cost deduction you want to use and stick to it. This is because switching from mileage to actual costs is not the best idea. And also, the calculations for depreciation will definitely need to be factored in.

How to Calculate Mileage for Work

In order to calculate mileage for work, it might also be necessary to keep all gas receipts because they relate to the business or organization you are working for.

Then, when you reach your business task, also note down the new number you see on the odometer. Now, this is where how to calculate mileage taxes for work comes into play. Simply substract the first number from the second number to get the result of the miles driven. Then the next and last thing to do is to multiply the number of miles you have driven by your company’s standard mileage reimbursement rate.

What Counts as Business Mileage?

The IRS is the legal government agency making laws such as what counts as business mileage. They increased the per-mile deduction for business driving from 31 cents to 58 cents.

Because the meet-up was for business and not pleasure.

If you only have a temporary workplace, then, it’s possible to claim the commute as business miles. Meanwhile, also, If you take any professional trip using a taxi, an Uber, or even a leased car, you can claim the per-mile deduction for that, too.
