Understanding how to deduct transportation costs could significantly reduce the tax burden on your small business. You and your employees likely incur various local transportation expenses each year, and they have tax implications.

Let’s start by defining “local transportation.” It refers to travel when you aren’t away from your tax home long enough to require sleep or rest. Your tax home is the city or general area in which your main place of business is located. Different rules apply if you’re away from your tax home for significantly more than an ordinary workday and you need sleep or rest to do your work.

Your work location

The most important feature of the local transportation rules is that your commuting costs aren’t deductible. In other words, the fare you pay or the miles you drive to get to work and home again are personal and not for business purposes. Therefore, no deduction is available. This is the case even if you work during the commute (for example, via a cell phone or laptop, performing business-related tasks on the subway).

An exception applies for commuting to a temporary work location outside of the metropolitan area where you live and normally work. “Temporary,” for this purpose, means a location where your work is realistically expected to last (and does, in fact, last) for no more than a year.

Work location to other sites

On the other hand, once you get to your work location, the cost of any local trips you take for business purposes is a deductible business expense. So, for example, the cost of travel from your office to visit a customer or pick up supplies is deductible. Similarly, if you have two business locations, the cost of traveling between them is deductible.

Recordkeeping

If your deductible trip is by taxi or public transportation, save a receipt or note the expense in a logbook. Record the date, amount spent, destination and business purpose. If you use your own car, note the miles driven instead of the amount spent. Also, note any tolls paid or parking fees, and keep receipts.

You must allocate your automobile expenses between business and personal use based on miles driven during the year. Proper recordkeeping is crucial in the event the IRS challenges you.

Your deduction can be computed using:

1. The standard mileage rate (for 2024, 67 cents per business mile) plus tolls and parking, or
2. Actual expenses (including depreciation, subject to limitations) for the portion of car use allocable to the business. For this method, you’ll need to keep track of all costs for gas, repairs and maintenance, insurance, interest on a car loan, and any other car-related costs.

Employees vs. self-employed

From 2018–2025, under the Tax Cuts and Jobs Act, employees can’t deduct unreimbursed local transportation costs. That’s because “miscellaneous itemized deductions” — including employee business expenses — are suspended (not allowed) for these years. (Self-employed taxpayers can deduct the expenses discussed in this article.) But beginning in 2026, business expenses (including unreimbursed employee auto expenses) of employees are scheduled to be deductible again, as long as the employee’s total miscellaneous itemized deductions exceed 2% of adjusted gross income. However, with Republican control in Washington, this unfavorable provision may be extended by Congress, and miscellaneous itemized deductions won’t be allowed.

If you operate a small business, or you’re starting a new one, you probably know you need to keep records of your income and expenses. In particular, you should carefully record your expenses in order to claim the full amount of the tax deductions to which you’re entitled. And you want to make sure you can defend the amounts reported on your tax returns if you’re ever audited by the IRS or state tax agencies.

Certain types of expenses, such as automobile, travel, meals and office-at-home expenses, require special attention because they’re subject to special recordkeeping requirements or limitations on deductibility.

It’s interesting to note that there’s not one way to keep business records. In its publication “Starting a Business and Keeping Records,” the IRS states: “Except in a few cases, the law does not require any specific kind of records. You can choose any recordkeeping system suited to your business that clearly shows your income and expenses.”

That being said, many taxpayers don’t make the grade when it comes to recordkeeping. Here are three court cases to illustrate some of the issues.

Case 1: Without records, the IRS can reconstruct your income

If a taxpayer is audited and doesn’t have good records, the IRS can perform a “bank-deposits analysis” to reconstruct income. It assumes that all money deposited in accounts during a given period is taxable income. That’s what happened in the case of the business owner of a coin shop and precious metals business. The owner didn’t agree with the amount of income the IRS attributed to him after it conducted a bank-deposits analysis.

But the U.S. Tax Court noted that if the taxpayer kept adequate records, “he could have avoided the bank-deposits analysis altogether.” Because he didn’t, the court found the bank analysis was appropriate and the owner underreported his business income for the year. (TC Memo 2020-4)

Case 2: Expenses must be business related

In another case, an independent insurance agent’s claims for a variety of business deductions were largely denied. The Tax Court found that he had documentation in the form of cancelled checks and credit card statements that showed expenses were paid. But there was no proof of a business purpose.

For example, he made utility payments for natural gas, electricity, water and sewer, but the records didn’t show whether the services were for his business or his home. (TC Memo 2020-25)

Case number 3: No records could mean no deductions

In this case, married taxpayers were partners in a travel agency and owners of a marketing company. The IRS denied their deductions involving auto expenses, gifts, meals and travel because of insufficient documentation. The couple produced no evidence about the business purpose of gifts they had given. In addition, their credit card statements and other information didn’t detail the time, place, and business relationship for meal expenses or indicate that travel was conducted for business purposes.

“The disallowed deductions in this case are directly attributable to (the taxpayer’s) failure to maintain adequate records,“ the court stated. (TC Memo 2020-7)
