Nobody likes paying more in taxes than they legally have to. Yet, every year, countless US small businesses overpay the IRS simply because they don't track their expenses properly or they miss out on legitimate tax deductions.
A tax deduction (or "write-off") is an expense the IRS allows you to subtract from your gross revenue, thereby lowering your taxable net income. The lower your taxable income, the less you owe in taxes. However, to claim a deduction, you must have accurate, up-to-date bookkeeping records to prove the expense was strictly for business.
In this guide, CountRights highlights the top tax deductions every US small business should be tracking to keep their hard-earned cash in their bank account.
1. The Home Office Deduction
If you run your business out of your home, the IRS allows you to deduct a portion of your housing expenses. To qualify, the space must be used exclusively and regularly as your principal place of business.
There are two ways to calculate this deduction:
- Simplified Method: You deduct $5 per square foot of your home office, up to a maximum of 300 square feet (capping at a $1,500 deduction). This is easy and requires no complex math.
- Actual Expense Method: You measure your office square footage against your total home square footage to get a percentage. You then deduct that percentage of your rent/mortgage interest, utilities, homeowners insurance, and property taxes. This method usually yields a much higher deduction.
2. Vehicle and Travel Expenses
If you drive for business—whether to meet clients, buy supplies, or visit a job site—you can deduct your vehicle expenses. You must keep a detailed mileage log (date, miles driven, and business purpose).
- Standard Mileage Rate: The IRS sets a rate per mile (e.g., 67 cents per mile for 2024). You simply multiply your business miles by this rate.
- Actual Expense Method: You track actual costs like gas, oil changes, repairs, insurance, and depreciation, and deduct the percentage used for business.
Additionally, airfare, hotels, and 50% of business meals while traveling out of town for work are fully deductible. Note: commuting from your home to your regular office is never deductible.
The Receipt Rule: For any meal or travel expense over $75, the IRS requires you to keep the receipt. However, for expenses under $75 (like a $4 coffee), a bank or credit card statement is usually sufficient. Still, keeping digital receipts in QuickBooks is the safest bet.
3. Section 179 Equipment Deduction
If you purchase heavy machinery, computers, office furniture, or vehicles for your business, you typically have to depreciate (spread out) the cost over several years. However, Section 179 is an incredible tax code that allows you to deduct the entire purchase price in the year you buy it.
For example, if you buy a $50,000 truck for your construction business in November, you can deduct the full $50,000 on that year's tax return, massively lowering your tax liability for that year.
4. Salaries, Wages, and Contractor Payments
The money you pay your team is fully deductible. This includes W-2 employee wages, payroll taxes, health insurance premiums, and bonuses. It also includes payments to independent contractors.
Just remember: if you pay a contractor $600 or more in a calendar year, you must issue them a 1099-NEC form by January 31st. Your bookkeeper can easily pull this report from your accounting software at the end of the year.
5. Professional Fees and Business Insurance
You can deduct fees paid to professionals who help your business. This includes:
- CPA and tax preparation fees
- Bookkeeping and payroll service fees (like CountRights)
- Lawyers and legal consultants
- Business liability insurance, property insurance, and cyber insurance premiums
6. Retirement Contributions (SEP IRA & Solo 401k)
One of the best ways for a small business owner to lower their tax bill while building wealth is to contribute to a retirement plan. Contributions to a SEP IRA (Simplified Employee Pension) or a Solo 401(k) are tax-deductible.
In 2024, you can contribute up to $69,000 to a SEP IRA. This deduction directly reduces your taxable income, making it a massive win-win for your future self and your current tax return.
Don't Mix Personal and Business: To claim these deductions, the IRS requires your expenses to be "ordinary and necessary" for your business. If you use your business debit card to buy personal groceries, you cannot deduct it. Commingling funds is the fastest way to trigger an IRS audit.
Conclusion
Taking advantage of every legal tax deduction is how smart US small businesses keep their cash flow strong. But to claim these write-offs, your books must be perfectly categorized and reconciled year-round.
