Tax Deductions Every Small Business Owner Should Know in 2025

Tax deductions are essential for small business owners looking to reduce their taxable income and keep more of their hard-earned money. As we move into 2025, understanding which business expenses qualify for deductions can help you lower your tax liability and improve your cash flow.

At JCB Financial Services, we help business owners maximize their tax savings by identifying deductions they may not even realize they qualify for. In this guide, we’ll cover some of the most important tax deductions you should be aware of for the 2025 tax year.

1. Home Office Deduction

If you run your business from home, you may qualify for the home office deduction. The IRS allows you to deduct a portion of your rent, mortgage interest, utilities, and home maintenance costs if you use a specific part of your home exclusively for business purposes.

Two ways to calculate:

• Simplified method: Deduct $5 per square foot (up to 300 sq. ft.).
• Regular method: Deduct the actual expenses based on the percentage of your home used for business.

2. Vehicle and Mileage Expenses

If you use your car for business, you can deduct mileage, gas, repairs, insurance, and lease payments. For 2025, the IRS standard mileage rate is expected to be around 65 cents per mile (check IRS updates for final rates).

What qualifies?

• Driving to client meetings
• Business-related errands
• Traveling for work purposes

💡 Tip: Keep a mileage log using an app like QuickBooks or Everlance to track business-related driving.

3. Business Meals

You can deduct 50% of the cost of meals when dining with clients, business partners, or employees. The meal must be business-related, and you should keep records of who attended and the purpose of the meeting.

🚨 Important: Entertainment expenses (e.g., sports tickets, concerts) are not deductible unless directly related to business activities.

4. Office Supplies and Equipment

Items used for your business—such as printers, laptops, office furniture, and business software—are deductible. Larger purchases may be eligible for Section 179 deductions, allowing you to deduct the full cost in the year of purchase instead of depreciating over time.

5. Marketing and Advertising Costs

Investing in advertising, website development, social media ads, and branding is 100% deductible. Whether you’re running Google Ads, Facebook Ads, or hiring a marketing consultant, these expenses can reduce your taxable income.

Deductible marketing expenses include:
✔️ Social media ads
✔️ Business website and hosting fees
✔️ Printing business cards and brochures
✔️ Sponsorships for local events

6. Health Insurance Premiums

If you’re self-employed, you may deduct health insurance premiums for yourself, your spouse, and dependents. This deduction applies even if you don’t itemize your deductions.

💡 Tip: If you offer health insurance to employees, you may qualify for small business tax credits.

7. Professional Services and Software

If you hire accountants, tax preparers, consultants, or legal professionals, their fees are deductible. Business software like QuickBooks, payroll services, and CRM tools also qualify.

8. Employee Salaries and Contractor Payments

Wages paid to employees are fully deductible, including bonuses, benefits, and payroll taxes. If you hire independent contractors, make sure to file 1099-NEC forms to stay compliant with IRS regulations.

9. Business Insurance

If you pay for liability insurance, professional insurance, or business property insurance, those costs are 100% deductible. Protecting your business doesn’t just keep you covered—it also helps lower your taxable income.

10. Retirement Contributions

Contributing to a SEP IRA, Solo 401(k), or SIMPLE IRA can lower your taxable income while helping you save for the future. Self-employed business owners can contribute up to 25% of their net earnings into a SEP IRA.

💡 Tip: Setting up a retirement plan for employees may also qualify you for small business tax credits.
