5 Commonly Missed Tax Deductions for Small Business Owners
If you're a small business owner trying to maximize your tax deductions, you're not alone in wondering:
“Am I missing something I could write off?”
Chances are—you probably are.
At DBR Bookkeeping, we see entrepreneurs overpay in taxes every year simply because they miss key deductions that could save them hundreds or even thousands of dollars. Here are 5 of the most commonly overlooked business expenses:
1. Business Interest (Loans + Credit Cards)
Interest paid on business loans, credit lines, and even business credit cards is deductible. Just make sure the debt is tied to business activity—and that you’re separating personal and business expenses.
2. Home Office Expenses
If you regularly work from a dedicated home office space, you can deduct a portion of your home-related expenses—like rent or mortgage interest, utilities, insurance, and repairs—based on the square footage used.
3. Business Mileage
Driving to client meetings, vendor visits, or networking events? Those miles count. At over 65 cents per mile (2025 IRS rate), tracking this can result in big savings. Use a mileage app or keep a simple log to make this count.
4. Software & Subscriptions
Monthly tools like Canva, Zoom, bookkeeping software (like QuickBooks), CRM platforms, and even online course platforms are all deductible if used for business.
5. Professional Services
Payments to bookkeepers, accountants, attorneys, consultants, and coaches are fully deductible business expenses. If they help you run or grow your business, write it off.
Most small businesses miss out on these deductions because their books aren’t organized, or they’re not sure how to track expenses properly.
At DBR Bookkeeping, we specialize in helping small business owners maximize deductions, clean up their books, and get tax-ready with confidence.
