Every dollar you can deduct is a dollar that lowers taxable income. Here are the most common deductions business owners miss—and how to claim them correctly.

Core deductions most small businesses qualify for

• Business mileage and travel
• Office supplies and software
• Phone and internet (business portion)
• Professional services (legal, accounting, bookkeeping)
• Insurance premiums

Home office (if you qualify)

To claim this, the space must be used regularly and exclusively for business. We can help determine if it applies to you.

Equipment and technology

Computers, tools, and furniture may qualify for Section 179 or bonus depreciation. Timing purchases can materially reduce tax.

Retirement contributions

SEP IRA and Solo 401(k) contributions can significantly lower taxable income while building long‑term savings.

Clean books matter

Accurate bookkeeping is what makes your deductions defensible. If you want help keeping records audit‑ready, see Bookkeeping & Year‑Round Support.
