17 Small-Business Tax Deductions People Forget

A deduction is simply a business expense that lowers the income you're taxed on. The catch? You only benefit from the ones you actually claim. Here are the legitimate write-offs we most often see small businesses miss.

The everyday ones people overlook

  1. Home office — if you use part of your home regularly and exclusively for business, a portion of rent, utilities, and insurance may qualify.
  2. Vehicle & mileage — business miles add up fast. Track them and choose the standard mileage rate or actual expenses.
  3. Phone & internet — the business-use percentage of your bills.
  4. Software & subscriptions — accounting tools, design apps, industry memberships.
  5. Bank & merchant fees — those little card-processing percentages are fully deductible.
  6. Continuing education — courses, certifications, and books that maintain or improve your skills.

The bigger ones worth planning around

  1. Startup costs — many expenses before you opened the doors can be deducted or amortized.
  2. Retirement plan contributions — a SEP-IRA or Solo 401(k) can shelter a large chunk of profit while building your future.
  3. Health insurance premiums — self-employed owners can often deduct their premiums.
  4. Section 179 / equipment — you can frequently deduct the full cost of qualifying equipment the year you buy it.
  5. Business use of a personal asset — that camera, trailer, or tool you also use for work.
  6. Professional fees — yes, the fees you pay your accountant and attorney are deductible.

The easy-to-miss extras

  1. Mileage to the bank, supplier, or client — not just big trips.
  2. Business meals — a percentage of qualifying meals with clients or while traveling.
  3. Bad debts — money you were owed and genuinely can't collect.
  4. Advertising & website — hosting, ads, business cards, signage.
  5. Wages to family members — legitimate pay for real work can shift income and add up to savings.
One firm rule: a deduction has to be ordinary and necessary for your business, and you need a record to back it up. "Creative" deductions aren't worth the risk — but missing real ones is just as costly in the other direction.

The real secret: good books

You can't deduct what you didn't track. The single best thing you can do for your tax bill is keep clean, current books throughout the year — so at tax time every dollar is already captured.
