The more small business tax deductions your business can legitimately take, the lower its taxable profit will be. In addition to putting more money into your pocket at the end of the year, the tax code provisions that govern deductions can also yield a personal benefit: a nice car to drive at a smaller cost or a combination business trip and vacation.
So, it's advantageous to pay careful attention to IRS rules on just what is—and isn't—deductible. Claiming all of the small business tax deductions (tax write-offs) to which you're entitled can ultimately save your business a lot of money.
By claiming tax deductions, small businesses can significantly reduce their taxable income and, ultimately, the taxes they owe. You owe tax only on the amount left over after your business's deductible expenses are subtracted from your gross income. The more deductions you take, the lower your net profit will be and the less tax you will have to pay.
When you're totaling up your business's expenses at the end of the year, don't overlook these important business tax deductions.
If you use your car for business or your business owns its own vehicle, you can deduct some of the costs of keeping it on the road. Mastering the rules of car expense deductions can be tricky but well worth your while.
The two methods of claiming expenses are:
If your auto is used for both business and pleasure, only the business portion produces a tax deduction. So, you must keep track of how often you use the vehicle for business and add it all up at the end of the year.
Certainly, if you own just one car or truck, no IRS auditor will let you get away with claiming that 100% of its use is related to your business. GPS-based apps are available that allow you to keep track of your driving, or you can use a paper logbook.
Once you're running a business, expenses such as advertising, utilities, office supplies, and repairs can be deducted as current business expenses—but not before you open your doors for business. The costs of getting a business started are capital expenses, and you may deduct $5,000 the first year you're in business; any remainder must be deducted in equal amounts over the next 15 years (180 months).
If you expect your business to make a profit immediately, you might be able to work around this rule by delaying paying some bills until after you're in business or by doing a small amount of business just to officially start.
However, if, like many businesses, you'll suffer losses during the first few years of operation, you might be better off taking the deduction over five years so you'll have some profits to offset.
Business books, including those that help you do without legal and tax professionals, are fully deductible as a cost of doing business.
Fees you pay to lawyers, tax professionals, or consultants generally can be deducted in the year incurred. But if the work clearly relates to future years, they must be deducted over the life of the benefit you get from the lawyer or other professional.
You can deduct the premiums you pay for any insurance you buy for your business as a business operating expense, including:
When you travel for business, you can deduct many expenses, including the cost of plane fare, costs of operating your car, taxis, lodging, meals, shipping business materials, cleaning clothes, and tips.
What about combining business and pleasure? It's okay, as long as business is the trip's primary purpose. But if you take your family along, you can deduct only your own expenses.
If you use credit to finance business purchases, the interest and carrying charges are fully tax-deductible. The same is true if you take out a personal loan and use the proceeds for your business.
However, under the Tax Cuts and Jobs Act, if your business profit is more than $25 million, you'll only be able to deduct 30% of your interest expenses. Real property businesses with more than $25 million in gross receipts may elect out of the 30% limitation by agreeing to depreciate their real property over a somewhat longer period.
Be sure to keep good records demonstrating that the money was used for your business.
Most small businesses are able to deduct the cost of equipment using bonus depreciation, expanded Section 179 expensing, and the $2,500 de minimis deduction. These deductions may be used for tangible personal property and computer software, but not real property, which must be depreciated over many years.
For used or new personal business property placed in service from September 27, 2017 through December 31, 2022, 100% of the cost may be deducted in a single year through bonus depreciation.
In later years, the first-year bonus depreciation deduction amount goes down as follows:
In addition, under Section 179 of the Internal Revenue Code, you can currently deduct up to an annual threshold amount of the cost of equipment and certain business assets you purchase and place in service that year and use over 50% of the time for your business (not personal use). The Section 179 annual limit is $1,160,000 for 2023 ($1,220,000 for 2024).
In addition to the annual limit, a phase-out applies to how much property can be deducted under Section 179 that starts when a business purchases more than $2.7 million in business property in a year. Once this annual investment limit is reached, the amount you can deduct under Section 179 is reduced dollar for dollar by the amount your purchases exceed the limit.
Finally, using a provision of the tax law called the "de minimis safe harbor," a business may deduct in a single year any tangible personal property that costs $2,500 or less, as stated on the invoice. You must file an election with your tax return to use this deduction.
If your business is a partnership, a limited liability company, or an S corporation (a corporation that has chosen to be taxed like a partnership), your business can make a charitable contribution and pass the deduction through to you, to claim on your individual tax return (but only if you itemize your personal deductions). If you own a regular (C) corporation, the corporation can deduct the charitable contributions.
If you've got some old computers or office furniture, giving it to a school or nonprofit organization can yield goodwill plus a tax benefit. But if the equipment has been fully depreciated (written off), you can't claim a deduction.
Taxes incurred in operating your business are generally deductible. How and when they're deducted depends on the type of tax:
You can deduct education expenses if they're related to your current business, trade, or occupation. The expense must be to maintain or improve skills required in your present business. (The cost of education that qualifies you for a new business or trade isn't deductible.)
The cost of ordinary advertising of your goods or services—websites, business cards, Google Adwords, and so on—is deductible as a current expense.
Promotional costs that create business goodwill—for example, sponsoring a peewee football team—are also deductible as long as a clear connection exists between the sponsorship and your business. For example, naming the team the "Southwest Auto Parts Blues" or listing the business name in the program is evidence of the promotion effort.
The Tax Cuts and Jobs Act created a new tax deduction for individuals who earn income through pass-through businesses, such as a:
Such individuals may deduct an amount up to 20% of their net income from each pass-through business they own. This deduction is in addition to all their other business deductions.
The pass-through deduction is a personal deduction pass-through owners can take on their returns whether or not they itemize. This deduction is scheduled to last from 2018 through 2025.
But this deduction is limited for people whose business is providing personal services, including people providing services in the fields of health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage services, investing and investment management, trading and dealing in securities or commodities, or any business where the principal asset is the reputation or skill of one or more of its owners (but there is an exception for architects and engineers).
A business owner who provides such services is entitled to the 20% pass-through deduction only if their 2023 taxable income from all sources after deductions is less than $364,200 if married filing jointly, or $182,100 if single. The deduction is phased out if income exceeds these limits. It disappears entirely for marrieds filing jointly whose income exceeds $464,200 and for singles whose income exceeds $232,100
If you're not involved in providing services, you can still qualify for a pass-through deduction if your business income exceeds these amounts, but it is subject to a special limit: Your deduction can't exceed:
This deduction is scheduled to end on January 1, 2026.
Employee salaries are fully deductible by the employer. Also deductible is the employer's share of payroll taxes.
Many employee fringe benefits are also deductible for the employer and tax-free for the employee—for example, employee health insurance.
When you hire an independent contractor—that is, a person who is not your employee—to perform services for your business, the cost is deductible as well. For example, you may deduct the cost of hiring a bookkeeper to do your books or a custodian to clean your offices.
You qualify for the home office deduction if you use a space in your home regularly and exclusively for your business. It can be your principal place of business, a place you meet clients or customers, or a place you use for administrative tasks. It can be all or part of a room or rooms in your home or a separate structure.
The amount of the deduction is based on the percentage of your home you use for your business office. The deduction includes the home office percentage of your rent or mortgage, utilities, depreciation if you own your home, insurance, home maintenance, and other home expenses. Expenses just for your home office are 100% deductible—for example, painting your home office or adding a carpet.
