What else can you deduct as a business expense? 

Charitable donations 

You might choose to make charitable donations part of your corporate social responsibility initiatives, which can help to attract new kinds of customers and employees. 

When making charitable donations, it is important to understand the potential tax implications.  

According to the IRS, you can deduct charitable contributions made to qualified organizations, such as: 

  • Non-profit organizations 
  • Religious organizations 
  • Certain educational institutions 

It is important to note that the amount of the donation you can deduct may be limited, depending on the organization and the type of donation.  

For example, the deduction for a donation of property may be limited to the property’s fair market value. In contrast, the deduction for a cash donation may be limited to a percentage of the business’s taxable income.  

However, you can carry any donation that exceeds the limit to future tax years. Keep accurate records and receipts of these donations.  

Education and training expenses 

Education and training expenses can be deductible as a business expense if they are directly related to your business or trade or required by law or condition of employment.

It’s important to note that education and training expenses are subject to certain limitations and restrictions.  

As you know, tax-deductible expenses must be reasonable and necessary.  

You cannot use them to qualify for a new trade or business—that may be deductible as a capital expense, subject to different rules and limitations. 

By deducting education and training expenses, you can invest in your people and improve their skills and knowledge while reducing your tax liability. 

Health insurance premiums for self-employed individuals 

Health insurance premiums for self-employed individuals can be deductible as a business expense under certain conditions.  

To qualify, the individual must not be eligible for coverage under an employer-sponsored health plan. The insurance plan must be established for the individual or their self-employed business. 

Self-employed individuals may be able to deduct the cost of health insurance premiums for themselves, their spouses, and their dependents.  

The deduction is taken on the individual’s personal-income tax return as an adjustment to income, which means it is available even if the individual does not itemize deductions. 

It’s important to note that there are limitations and restrictions on deducting health insurance premiums.  

The deduction cannot: 

  • Exceed the individual’s net income from the business.  
  • Be taken for any month the individual was eligible for coverage under an employer-sponsored health plan.  
  • Be available for any month in which the individual was eligible to participate in a subsidized health plan maintained by an employer of the individual’s spouse. 

Retirement-plan contributions 

Retirement-plan contributions can be a valuable tax deduction for businesses, allowing owners and employees to save for retirement while reducing tax liabilities. 

Several retirement-plan types are available to businesses, each with its contribution limits and tax benefits. 

According to the IRS, contributions to a traditional 401(k) or IRA plan are tax deductible up to certain limits. The amount that can be deducted depends on the type of plan and the individual’s income.  

In addition to the potential tax benefits, contributing to a retirement plan can help your people save for their future and ensure financial security in retirement. 

You might want to offer matching contributions to their retirement plans, which can further increase the funds they save for retirement. 

It is important to keep accurate records and receipts of retirement plan contributions, as they may be subject to audit by the IRS.  

Additionally, it is important to understand the rules and regulations governing retirement plans, as there may be penalties for early withdrawals or other violations.  

How accounting software can track spend and categorize your business-expense deductions
