Strong financial management significantly contributes to sustained growth and success in small business ownership. One powerful tool at the disposal of entrepreneurs is the strategic use of tax deductions. Understanding and leveraging these deductions can significantly impact a business’s bottom line. This blog post will delve into some essential tax deductions that every small business owner should know to optimize their financial standing.

Home Office Deduction:

For many small business owners, working from home has become the norm. The home office deduction allows you to claim expenses related to the business use of your home, such as a portion of your mortgage interest, insurance, utilities, and home repairs. To qualify, your home office must be your principal place of business and be used regularly and exclusively for business activities.

Home office deductions are based on the percentage of your home devoted to business use. 

This percentage is calculated by taking the square footage of your home office and dividing it by the square footage of your entire home. The resulting percentage is then applied to relevant expenses. 

Depending on your business structure, you will realize these deductions differently. For example, S Corporation owners should reimburse themselves through their company, following the rules of an accountable plan. 

Business Vehicle Expenses:

If you use a vehicle for business purposes, you may be eligible for deductions related to its operation and maintenance. These deductions may include expenses such as mileage, fuel, insurance, and repairs. Keeping detailed records of your business-related travel is essential to maximizing this deduction.

You can only claim actual expenses or the IRS standard mileage rate. Business owners with separate business vehicles will often track actual expenses. Those business owners using their personal car occasionally for business will often track mileage

Mileage can be easily tracked with mobile phone apps like Mile IQ. 

Retirement Plan Contributions:

Contributing to a retirement plan secures your financial future and can offer tax advantages. Various retirement account options are available to small business owners depending on your company’s business structure and whether you are a solopreneur or have employees. 

Each account type has unique rules surrounding contribution limits and the inclusion of employees. Owing to the many options and complex rules, it’s best to consult both your financial planner and tax professional to determine which account to open and how much you can contribute. 

By understanding and leveraging the deductions outlined above, small business owners can optimize their financial position, reduce tax liabilities, and reinvest in the growth of their enterprises.
