As a small business owner, one of the most crucial aspects of managing your finances is understanding what deductions you can take advantage of to minimize your tax burden. Deductions allow you to subtract certain expenses from your taxable income, ultimately reducing the amount of tax you owe. However, navigating the maze of tax rules and regulations can be daunting. In this blog post, we’ll explore some of the most common deductions available to small business owners. 


  1. Home Office Deduction 

If you use part of your home regularly and exclusively for conducting business, you may be eligible for the home office deduction. This deduction allows you to deduct a portion of your home-related expenses, such as mortgage interest, property taxes, utilities, and maintenance costs, based on the percentage of your home office to total square feet of your house, used for business purposes.  For example – if you use your spare bedroom strictly for your office, and it’s 100 square feet, you take the percentage of that based on your total square footage of your house, so if it’s 1000 square feet, then you can deduct 10% of all home expenses as business expenses.  Please keep in mind that your office space must be in an area that is only used for your office.  You cannot use multi purpose rooms and claim the whole space, i.e. your dining room or living room that you use for both business and personal use.  


2. Business Expenses

Small business owners can deduct a wide range of ordinary and necessary expenses incurred in the course of operating their business. This includes expenses such as: 

– Office supplies

– Rent for office space or equipment

– Utilities

– Internet and phone bills

– Professional services (e.g., legal or accounting fees)

– Advertising and marketing costs

– Business insurance premiums

– Travel expenses (e.g., mileage, lodging, meals)

– Meals with Clients or Employees (subject to certain limitations) – Keep in mind that Meals (both business and travel) are now only deducted at 50% on your tax return, and Entertainment is no longer included as a deductible expense.  If you take a client to a Baseball game, the tickets to the game are not deductible, however if you purchase food at the baseball game, then you can deduct the food, again at 50%.


  1. Depreciation 

Depreciation allows you to deduct the cost of business assets over time, reflecting their gradual loss of value due to wear and tear, deterioration, or obsolescence. You can typically depreciate tangible assets such as equipment, machinery, vehicles, and furniture over their useful life. Additionally, the Section 179 deduction allows you to deduct the full purchase price of qualifying assets in the year they are placed in service, subject to certain limitations.

 Keep in mind that any equipment (i.e. computers, or some other business equipment) can be directly expensed if below the $2,500 threshold.  If you purchase a new laptop under $2,500, you do not have to depreciate it over the next few years, but instead you can directly expense it. 


  1. Retirement Contributions

 Contributions to retirement plans can be deducted as business expenses, providing both tax savings and long-term financial security. Small business owners have various retirement plan options to choose from, such as SEP-IRAs, SIMPLE IRAs, solo 401(k) plans, and Keogh plans, each with its own contribution limits and requirements.

You have till you file your tax return to claim these deductions, which makes them a game changer when it comes to filing taxes, especially if you owe.  You may be able to reduce your tax liability by making a contribution to your retirement.  


  1. Health Insurance Premiums

 Self-employed individuals, including small business owners, may be able to deduct the cost of health insurance premiums for themselves, their spouses, and their dependents. This deduction is taken on the front page of Form 1040, reducing your adjusted gross income (AGI) and thus your taxable income.


  1. Education and Training Expenses

 Investing in education and training to improve your skills or expand your knowledge in your field can be deductible as a business expense. This includes the cost of workshops, seminars, courses, books, and other materials related to your business.  This also includes any travel to get there, and meals during the course of the workshop, or conference.  Again, keep in mind that the meals are still deducted at 50%.  


  1. Bad Debts

 If you have outstanding invoices that are unlikely to be paid, you may be able to deduct them as bad debts. However, there are specific IRS requirements for claiming bad debt deductions, so be sure to familiarize yourself with the rules.  Also, this is more for those that file a tax return on an accrual basis.  If you are on a cash basis, then this would not apply to you as you do not recognize revenue that you have not received any actual cash payment for.  


  1. Software and Technology Expenses

 In today’s digital age, software and technology play a crucial role in running a successful business. Expenses related to purchasing and maintaining software, computers, peripherals, and other technology equipment are generally deductible as business expenses.



Taking advantage of available deductions is essential for small business owners to optimize their tax situation and maximize their after-tax income. However, it’s important to keep accurate records and stay informed about changes to tax laws and regulations that may affect your eligibility for deductions. Consulting with a qualified accounting professional can also provide valuable guidance tailored to your specific circumstances. By understanding and leveraging the deductions available to you, you can keep more of your hard-earned money and support the growth and success of your small business.
