For small business owners, knowing which expenses are deductible is one of the most effective ways to reduce taxable income and boost profitability. Still, many owners miss out on legitimate deductions or fail to document them properly—mistakes that can lead to paying more in taxes than necessary or facing challenges during an audit. With the right strategy and solid bookkeeping, you can confidently claim every deduction you’re entitled to.
Home Office Deduction
With more business owners working remotely, the home office deduction has become increasingly valuable. If you use a dedicated space in your home exclusively and regularly for business, you may be able to deduct a portion of expenses such as rent, utilities, insurance, and repairs.
The IRS offers two options:
-
Simplified method: A flat $5 per square foot, up to 300 square feet.
-
Actual-expense method: Potentially larger deductions, but requires detailed recordkeeping.
Vehicle and Mileage Expenses
If you use your vehicle for business, you can deduct either the standard mileage rate or actual expenses like gas, insurance, repairs, and depreciation. To qualify, you must keep consistent mileage logs noting dates, destinations, and business purposes.
Remember: commuting to and from your regular workplace is not deductible, but trips for client meetings, project sites, or business errands generally are.
Meals and Travel
Business meals are typically 50% deductible, as long as they are business-related and properly documented—including who you met with and why.
Travel expenses such as airfare, lodging, rental cars, and certain incidental costs are deductible when the trip is primarily for business. Keeping detailed receipts and agendas helps support these deductions if the IRS asks for proof.
Depreciation and Equipment Deductions
Tax incentives like Section 179 and bonus depreciation allow businesses to deduct the full cost of qualifying equipment, software, vehicles, and certain improvements in the year they are placed in service. For businesses investing in growth, these deductions can meaningfully lower taxable income.
However, accurate tracking of asset purchases and usage is critical to remain compliant.
Retirement Plan Contributions
Setting up a retirement plan not only supports long-term savings goals but also creates a tax deduction for the business. Popular options include SEP IRAs, SIMPLE IRAs, and Solo 401(k)s, each with different contribution limits and requirements. The right plan depends on your business structure and whether you have employees.
Recordkeeping Matters
While the IRS doesn’t require specialized software, your records must be organized and complete. Keep receipts, invoices, bank and credit card statements, and mileage logs accessible. Strong bookkeeping practices ensure you maximize deductions and reduce the likelihood of IRS scrutiny.
Final Thoughts
Many small business owners leave money on the table simply because they’re unsure what qualifies as a deductible expense—or they lack the documentation to support it. Reviewing expenses throughout the year, rather than waiting until tax season, helps ensure you capture every possible deduction. Paired with guidance from a trusted accountant, a proactive approach keeps your business compliant and minimizes your tax burden.
