If you read the Internal Revenue Code (and you probably don’t want to!), you may be surprised to find that most business deductions aren’t specifically listed. For example, the tax law doesn’t explicitly state that you can deduct office supplies and certain other expenses. Some expenses are detailed in the tax code, but the general rule is contained in the first sentence of Section 162, which states you can write off “all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business.”

Basic definitions

In general, an expense is ordinary if it’s considered common or customary in the particular trade or business. For example, insurance premiums to protect a store would be an ordinary business expense in the retail industry.

A necessary expense is defined as one that’s helpful or appropriate. For example, let’s say a car dealership purchases an automated external defibrillator. It may not be necessary for the operation of the business, but it might be helpful and appropriate if an employee or customer suffers cardiac arrest.

It’s possible for an ordinary expense to be unnecessary — but, in order to be deductible, an expense must be ordinary and necessary.

In addition, a deductible amount must be reasonable in relation to the benefit expected. For example, if you’re attempting to land a $3,000 deal, a $65 lunch with a potential client should be OK with the IRS. (Keep in mind that the Tax Cuts and Jobs Act eliminated most deductions for entertainment expenses but retained the 50% deduction for business meals.)

Examples of taxpayers who lost deductions in court

Not surprisingly, the IRS and courts don’t always agree with taxpayers about what qualifies as ordinary and necessary expenditures. Here are three 2023 cases to illustrate some of the issues:

1. A married couple owned an engineering firm. For two tax years, they claimed depreciation of $76,264 on three vehicles, but didn’t provide required details including each vehicle’s ownership, cost and useful life. They claimed $34,197 in mileage deductions and provided receipts and mileage logs, but the U.S. Tax Court found they didn’t show any related business purposes. The court also found the mileage claimed included commuting costs, which can’t be written off. The court disallowed these deductions and assessed taxes and penalties. (TC Memo 2023-39)

2. The Tax Court ruled that a married couple wasn’t entitled to business tax deductions because the husband’s consulting company failed to show that it was engaged in a trade or business. In fact, invoices produced by the consulting company predated its incorporation. And the court ruled that even if the expenses were legitimate, they weren’t properly substantiated. (TC Memo 2023-80)

3. A physician specializing in gene therapy had multiple legal issues and deducted legal expenses of $360,295 for two years on joint Schedule C business tax returns. The Tax Court found that most of the legal fees were to defend the husband against personal conduct issues. The court denied the deduction for personal legal expenses but allowed a deduction for $13,000 for business-related legal expenses. (TC Memo 2023-42)

Proceed with caution

The deductibility of some expenses is clear. But for other expenses, it can get more complicated. Generally, if an expense seems like it’s not normal in your industry — or if it could be considered fun, personal or extravagant in nature — you should proceed with caution. And keep careful records to substantiate the expenses you’re deducting.

The Tax Cuts and Jobs Act liberalized the rules for depreciating business assets. However, the amounts change every year due to inflation adjustments. And due to high inflation, the adjustments for 2023 were big.

We have been advising our clients on these changes, but we wanted to send out a summary of the updates.

Here are the numbers that small business owners need to know.

Section 179 deductions

For qualifying assets placed in service in tax years beginning in 2023, the maximum Sec. 179 deduction is $1.16 million. But if your business puts in service more than $2.89 million of qualified assets, the maximum Sec. 179 deduction begins to be phased out.

Eligible assets include depreciable personal property such as equipment, computer hardware and peripherals, vehicles and commercially available software.

Sec. 179 deductions can also be claimed for real estate qualified improvement property (QIP), up to the maximum allowance of $1.16 million. QIP is defined as an improvement to an interior portion of a nonresidential building placed in service after the date the building was placed in service. However, expenditures attributable to the enlargement of a building, elevators or escalators, or the internal structural framework of a building don’t count as QIP and usually must be depreciated over 39 years. There’s no separate Sec. 179 deduction limit for QIP, so deductions reduce your maximum allowance dollar for dollar.

For nonresidential real property, Sec. 179 deductions are also allowed for qualified expenditures for roofs, HVAC equipment, fire protection and alarm systems, and security systems.

Finally, eligible assets include depreciable personal property used predominantly in connection with furnishing lodging, such as furniture and appliances in a property rented to transients.

Deduction for heavy SUVs

There’s a special limitation on Sec. 179 deductions for heavy SUVs, meaning those with gross vehicle weight ratings (GVWR) between 6,001 and 14,000 pounds. For tax years beginning in 2023, the maximum Sec. 179 deduction for heavy SUVs is $28,900.

First-year bonus depreciation has been cut

For qualified new and used assets that were placed in service in calendar year 2022, 100% first-year bonus depreciation percentage could be claimed.

However, for qualified assets placed in service in 2023, the first-year bonus depreciation percentage dropped to 80%. In 2024, it’s scheduled to drop to 60% (40% in 2025, 20% in 2026 and 0% in 2027 and beyond).

Eligible assets include depreciable personal property such as equipment, computer hardware and peripherals, vehicles and commercially available software. First-year bonus depreciation can also be claimed for real estate QIP.

Exception: For certain assets with longer production periods, these percentage cutbacks are delayed by one year. For example, the 80% depreciation rate will apply to long-production-period property placed in service in 2024.

Passenger auto limitations

For federal income tax depreciation purposes, passenger autos are defined as cars, light trucks and light vans. These vehicles are subject to special depreciation limits under the so-called luxury auto depreciation rules. For new and used passenger autos placed in service in 2023, the maximum luxury auto deductions are as follows:

• $12,200 for Year 1 ($20,200 if bonus depreciation is claimed),
• $19,500 for Year 2,
• $11,700 for Year 3, and
• $6,960 for Year 4 and thereafter until fully depreciated.

These allowances assume 100% business use. They’ll be further adjusted for inflation in future years.

Advantage for heavy vehicles

Heavy SUVs, pickups, and vans (those with GVWRs above 6,000 pounds) are exempt from the luxury auto depreciation limitations because they’re considered transportation equipment. As such, heavy vehicles are eligible for Sec. 179 deductions (subject to the special deduction limit explained earlier) and first-year bonus depreciation.

Here’s the catch: Heavy vehicles must be used over 50% for business. Otherwise, the business-use percentage of the vehicle’s cost must be depreciated using the straight-line method and it’ll take six tax years to fully depreciate the cost.
