15 Essential Tax Deductions Every Small Business Owner Should Know About
Tax season can feel overwhelming for small business owners and freelancers — but it’s also a huge opportunity to legally lower your taxable income and keep more cash in your pocket. The key? Knowing exactly what you can write off.
In this guide, I’ll break down 15 essential tax deductions you might be overlooking, so you can save money and stay compliant with the IRS.
📊 1️⃣ Home Office Deduction
If you run your business from a dedicated space in your home, you can claim a portion of your rent or mortgage, utilities, and insurance. The IRS offers two methods: a simplified option of $5 per square foot (up to 300 sq. ft.) or the actual expense method based on your home’s expenses.
📊 2️⃣ Business Meals
You can deduct 50% of qualifying business meals with clients, employees, or prospects — as long as the meal is business-related and you keep a record of the date, amount, and purpose.
📊 3️⃣ Internet and Phone Expenses
If you use your internet and phone for business, you can deduct the portion of these bills that relate to your business activity. Keep a clear record of your business vs. personal use.
📊 4️⃣ Professional Services
Payments to accountants, attorneys, consultants, bookkeepers, or marketing professionals are fully deductible as business expenses.
📊 5️⃣ Advertising and Marketing
Expenses for promoting your business — including Facebook or Google ads, business cards, website hosting, and social media management — are deductible.
📊 6️⃣ Office Supplies and Equipment
From printer ink and pens to laptops and standing desks, these everyday office expenses add up and are deductible. Larger equipment purchases may need to be depreciated over time, depending on cost.
📊 7️⃣ Business Insurance
Business liability insurance, professional liability policies, and other types of coverage you carry for your business are tax-deductible.
📊 8️⃣ Continuing Education
Expenses for business-related courses, certifications, workshops, or webinars are deductible if they maintain or improve your skills for your current business.
📊 9️⃣ Travel Expenses
When traveling for business, you can deduct airfare, hotels, car rentals, business-related meals, and even a portion of your mileage if driving your own vehicle.
📊 🔟 Vehicle Expenses
If you use your personal vehicle for business, you can deduct mileage (70 cents per mile for 2025) or actual expenses like gas, repairs, and insurance based on the business use percentage.
📊 1️⃣1️⃣ Subscriptions and Software
Ongoing subscriptions like Canva Pro, QuickBooks, or industry journals that support your business are fully deductible.
📊 1️⃣2️⃣ Bank Fees and Payment Processing
Transaction fees from Stripe, PayPal, or your business bank account are deductible business expenses.
📊 1️⃣3️⃣ Depreciation
For big-ticket purchases like equipment or furniture, you may be able to deduct the cost over several years through depreciation. The IRS offers Section 179 and bonus depreciation rules to potentially expense more upfront.
📊 1️⃣4️⃣ Salaries and Wages
If you pay employees or contractors, those wages and benefits (including payroll taxes) are deductible.
📊 1️⃣5️⃣ Retirement Contributions
Contributions you make to your own SEP IRA, Solo 401(k), or other small business retirement plans are deductible, helping you save for the future and reduce your taxable income.

- Work with a tax professional: Especially if you’re unsure about certain deductions.
