Attention to expense deductions may not play a prominent role in the financial planning process for small businesses and startups—and that may be costing them. Sure, you’re focused on customer service and improving your products and services. But some easy moves could significantly lessen your tax bill.

For example, say you’re putting 250 miles per week on your private vehicle to get products out to customers. It may seem time-consuming to keep a log separating business and personal use, but you’re losing out on close to $600 in deductions. Or maybe you shuttered your office and started running your company from a spare room. As long as the space is exclusively used for business, you can deduct $5 for every square foot, up to $1,500.

Business expenses are the costs of running a company and generating sales. Given that broad mandate, the IRS doesn’t provide a master list of allowable small-business and startup deductions. As long as an expense is “ordinary and necessary” to running a business in your industry, it’s deductible. That makes it well worth the time to organize your spending so your business takes all legitimate write-offs, creates an effective financial plan, pays the proper amount in quarterly taxes—and doesn’t need to sweat an audit.

What Is a Tax-Deductible Business Expense?

Which expenses may be written off varies depending on the nature of your business. Start by reviewing Internal Revenue Service Publication 535, which discusses the deductibility of common business expenses and general rules for filing your taxes.

Those “ordinary and necessary” expenses must be incurred in an organization motivated by profit. Even if your small business faces financial problems and doesn’t actually generate a profit, the intent needs to be there. Otherwise, the IRS may determine your business is a hobby and disallow expenses.

The IRS also suggests distinguishing usual business expenses from categories that fall under the cost of goods sold (COGs) and capital expenses to ensure accuracy, since some business expenses cannot be deducted in the year they’re incurred.

What are Business Expense Categories?

By developing expense categories that fit your business and recording and organizing expenditures as you go, you’ll find it easier to get all the deductions you’re due.

You’ll also save significant headaches for your bookkeeper or tax preparer. Speaking of, it’s worth spending time with a financial adviser to understand the types of expenses you can and can’t include in a specific category.

Below is an example small-business expense categories list that applies to most companies, outlining what’s included and how you can qualify for a deduction. Add to this industry-specific categories, such as R&D costs or spending to seek VC funding.

36 Business Expense Categories for Small Businesses and Startups

  1. Advertising: This covers the cost of items and services to directly promote or market your business. Examples include fees paid to advertising or marketing companies to produce promotional materials, billboards, brochures, posters, websites and social media images. You may even deduct spending on a PR campaign.

  2. Continuing education: This can include courses for continuing education or seminars to stay current on industry trends. Relevant materials, books and registration fees for you and your employees are tax-deductible. You can also deduct payments made to employees to reimburse them for relevant educational expenses.

  3. Credit and collection fees: Businesses that use accrual basis accounting, where revenue and expenses are recorded when they’re earned or incurred even if no money changes hands at that point, can deduct unpaid invoices as business bad debt. Any fees spent trying to collect on debt, such as hiring an outside company to collect what’s owed, also count. A better bet: Minimize bad debt and increase cash flow by optimizing your billing processes.

  4. Bank fees: Interest paid on business loans, ongoing credit lines and business credit cards are tax-deductible expenses. Bank fees, such as monthly maintenance or overdraft fees, also count.

  5. Dues and subscriptions: Subscriptions to industry magazines or journals related to your business can be deducted on your taxes. Membership fees include those paid to professional or trade associations that can help promote your business and even to your local Chamber of Commerce.

  6. Employee benefit programs: Payments made toward benefits such as disability insurance, life insurance, dependent care assistance, health plans for you and your employees and adoption assistance are tax-deductible. Note that this is one area, along with workers’ compensation insurance, where companies tend to spend more than they need to.

  7. Insurance: Besides that workers’ compensation insurance, you can deduct premiums for business-related insurance, including for liability, malpractice and real estate. Auto insurance premiums on a personal vehicle are a bit more complicated: If you deduct a flat mileage rate, you can’t itemize and must use the actual expense method, where you determine what it actually costs to operate the car for the portion of the overall use of the car that’s business use.

  8. Maintenance and repairs: Companies that use fleet vehicles as part of their operations can deduct the portion used for business. Deductible expenses include parking fees and gas. Otherwise, you can choose to utilize the standard mileage rate. Additionally, repair and maintenance of other types of equipment and machinery used in your business can also count.

    Under actual expenses calculations for vehicles, you may include gas, oil, repairs, tires, insurance, registration fees, licenses and depreciation (or lease payments) prorated to the total business miles driven.

  15. Rent: Any rental payments made to occupy a warehouse for inventory or office space to conduct business are tax deductible. Your business structure—C corporation (C-corp) or S corporation (S-corp)—dictates whether you can pay a reasonable amount to rent property from shareholders.

  16. Salaries and other compensation: Employee salaries, gross wages, commissions, bonuses and other types of compensation count as tax-deductible expenses. Compensation can even extend to salaries paid to children and spouses, provided payments were made through payroll and those individuals performed services for your business.

3 Steps to Categorize Expenses for Your Small Business or Startup

Poor tax compliance and inconsistent cash flow are among the top 10 financial challenges for small businesses. You can break that mold by being consistent in categorizing expenses. That allows you to see where and how much you’re spending to operate your company while being prepared come tax time.

You’ll also gather insights that will enable you to create a financial statement that adds visibility into profitability and cash flow. These statements are required for audits and are often requested by investors.

Here are three steps to categorize business expenses.

  1. Determine correct categories for your specific business. Choosing the right categories will depend on your industry. For example, a greeting card business may have dedicated categories for shipping and storage rental, whereas software-as-a-service (SaaS) companies may have categories for digital services.

    Start by identifying the expense categories your business uses the most—that financial statement will help here—and ones that you’ll need to grow. Refer to the list above to get started.

  2. Reconcile and review financial accounts regularly. Reviewing financial accounts is a good habit that will encourage you to stay on top of your expenditures. Reconciling bank statements can be easily done using accounting software. If you find you’re having challenges, a business-only credit card is a top expense management best practice.

  3. Assign a category to all transactions. Using the list of categories you came up with, look at your spending details and assign anything deductible. Pay particular attention to where receipts are required. Note that keeping business and personal finances separate is a top financial tip for small businesses and shields you from liability, so as you assign an expense, make sure it’s business-related.

What Else can I Deduct as a Business Expense?

As we’ve mentioned, your home can yield many deduction opportunities, based on the percentage of space your office occupies—but you’ll need to itemize mortgage interest, utilities, insurance and property taxes. Or, you can claim the standardized deduction, which is $5 per square foot up to 200 square feet.

A few other items you may not have considered:

The Work Opportunity Tax Credit (WOTC) is a Federal tax credit available to employers for hiring individuals from certain groups, including some veterans and disabled individuals, who face significant barriers to employment.

Costs to protect intellectual property created by you or your employees, such as software code, a logo for your business or a patent for a new product or service.

Losses from a natural disaster or crime. If a fire or flood destroys your stock, or items are stolen, you may deduct losses not covered by your insurance.

Use Accounting Software to Track Spending and Categorize Business Expenses

One of the easiest ways for business owners to categorize expenses and track spending is to use accounting software, which often has prepopulated business categories. You can amend or add as needed, and it will automatically compile transactions.

Accounting software also helps you to use the data from your expenses to run profit and loss reports. Doing so shows you the amount you’re spending in each category so you can assess whether you need to get your costs under control or if you’re on track. You can break down spending at specific time intervals to see how expenses change. These reports simplify the deduction process while revealing your annual business expenses.
