What Are the Most Common Small Business Tax Deductions?

As a small business owner, managing finances effectively is crucial for long-term success. One key way to reduce your tax burden and increase profitability is by understanding and leveraging small business tax deductions. These deductions allow business owners to subtract eligible expenses from their total income, reducing the amount of taxable income.

At Milestone Certified Public Accountants, located in Pleasanton, California, we specialize in helping businesses throughout the Tri-Valley region identify and maximize these tax-saving opportunities. Whether you’re just starting out or scaling your operations, our experienced team offers expert CPA services tailored to your business goals.

Understanding Tax Deductions

A tax deduction is a business expense that can be subtracted from your taxable income. By lowering your taxable income, deductions ultimately reduce the total taxes owed to the IRS. For small businesses, this can mean significant savings over time.

It’s important to note that deductions differ from tax credits. While deductions reduce the income on which you are taxed, credits directly reduce the amount of tax you owe.

Knowing what qualifies as a deduction and how to track these expenses can help small businesses optimize their tax strategy. That’s where working with a trusted CPA firm makes all the difference.

Common Small Business Tax Deductions

1. Home Office Deduction

If you operate your business from a home office, you may be eligible for the home office deduction. This applies to any space used exclusively and regularly for business.

There are two methods for calculating this deduction:

  • Simplified method: $5 per square foot (up to 300 sq. ft.)
  • Actual expense method: A percentage of actual home expenses like mortgage interest, utilities, and insurance

Learn more about eligibility in IRS Publication 535.

2. Business Expenses

Common operational expenses such as:

  • Office supplies (paper, pens, software subscriptions)
  • Rent and utilities
  • Internet and phone services
  • Marketing and advertising costs

These costs are fully deductible when they are necessary and ordinary for your business.

Refer to the IRS guidelines for more information: IRS Business Expenses

3. Vehicle Expenses

If you use a vehicle for business, the associated costs may be deductible. These include:

  • Mileage (IRS standard mileage rate for 2025)
  • Gas and oil
  • Maintenance and repairs
  • Depreciation

You can choose between tracking actual expenses or using the standard mileage rate. Always keep detailed logs and receipts.

For detailed IRS information, check Publication 463.

4. Employee Salaries and Benefits

Wages paid to employees, including bonuses, commissions, and taxable fringe benefits, are deductible. Additionally, contributions to employee retirement plans, health insurance, and other benefit programs are considered valid deductions.

Ensure proper classification of employees and maintain compliant payroll records.

5. Depreciation of Assets

When you purchase business assets like computers, machinery, or furniture, you may be able to deduct the cost over several years through depreciation. Section 179 of the IRS tax code allows businesses to deduct the full purchase price of qualifying equipment in the year it’s placed into service.

This is particularly beneficial for capital-intensive businesses.

Maximizing Your Deductions

Here are a few tips to ensure you’re making the most of your deductions:

  • Keep accurate and organized records of all business expenses.
  • Use accounting software or hire a professional bookkeeper.
  • Separate personal and business expenses.
  • Work with a licensed CPA to review and update your tax plan regularly.

A proactive tax strategy can mean the difference between overpaying and optimal tax savings.
