Small Business Tax Deductions You Might Be Missing

The tax code is full of legitimate deductions for business owners — and every one you miss is money you hand to the IRS for no reason. Software won't always catch them, because it only knows what you enter. Here are the deductions Middle Tennessee small business owners overlook most, and what it takes to claim them safely.

1. Home office deduction

If you use part of your home regularly and exclusively for business, you can deduct a portion of your rent or mortgage interest, utilities, insurance and repairs. The simplified method allows a flat rate per square foot; the actual-expense method can be worth more. This deduction is available to plenty of owners who wrongly assume they don't qualify.

2. Business mileage and vehicle costs

Driving for business — to clients, job sites, the bank, the supply store — is deductible. You can use the standard mileage rate or track actual vehicle expenses. The key is a contemporaneous log: date, miles and purpose. A mileage app makes this painless and stands up if the IRS ever asks.

3. Retirement contributions

A SEP-IRA, Solo 401(k) or SIMPLE IRA lets you sock away money for retirement and reduce your taxable income, often by far more than a standard IRA allows. For profitable business owners this is one of the biggest legal tax reducers available — and it's frequently overlooked.

4. Self-employed health insurance

If you're self-employed and pay for your own health insurance, you can generally deduct those premiums — including for your spouse and dependents — even if you don't itemize. Many owners pay these premiums all year and never take the write-off.

5. Startup and organizational costs

Launched recently? You can typically deduct up to $5,000 of startup costs and $5,000 of organizational costs in your first year, with the rest amortized over time. Legal fees, market research, and pre-opening expenses often qualify.

6. The deductions people forget

• Software and subscriptions — accounting tools, design apps, industry memberships.
• Professional fees — your accountant, attorney and consultants.
• Continuing education — courses, certifications and books that maintain or improve your skills.
• Bank and merchant fees — business account fees and payment-processing charges add up.
• Business use of your phone and internet — the business-use percentage is deductible.
• Bad debts — money you were owed and couldn't collect, in certain cases.

The rules that keep deductions safe

Two principles keep you out of trouble. First, an expense must be ordinary and necessary for your business. Second, you need documentation — receipts, logs and a clear business purpose. This is exactly why good bookkeeping matters: clean records mean you actually capture every deduction instead of guessing at year-end.

The safest way to make sure you're claiming everything you're entitled to — and nothing you're not — is to work with a professional who does this every day. If you'd like a second set of eyes on your return, our business tax and planning services are built for exactly that.
