Common Small Business Tax Deductions
Covenant Tax and Accounting Solutions (CTAS) helps business owners understand which expenses qualify as tax deductions. Properly leveraging these deductions can reduce taxable income, improve cash flow, and strengthen overall financial performance.
Startup Costs
If you recently launched your business, you may deduct up to $5,000 in startup costs, including:
- Legal and accounting fees
- Market research
- Initial advertising
Phaseout Rules:
- Deduction reduces dollar-for-dollar if startup costs exceed $50,000.
- No immediate deduction if costs exceed $55,000; costs must be amortized over 15 years (180 months).
Tip: Distinguish between startup costs and organizational costs—both qualify for up to $5,000 deductions if phaseout thresholds aren’t exceeded.
CTAS Guidance: Structure deductions strategically if expenses exceed $5,000. Generate revenue early to transition out of “startup” status, potentially allowing more immediate deductions.
Home Office Deduction
If you operate from home, the workspace must be used regularly and exclusively for business purposes. Two calculation methods exist:
   Simplified Method
- $5 per square foot, up to 300 sq. ft. (Max $1,500)
   Regular Method
- Deduct a prorated portion of mortgage/rent, utilities, insurance, repairs, and maintenance
CTAS Guidance: Clearly define your home office space and keep detailed records. Exclusive business use is required.
Lease Agreements and Utility Expenses
- Rent: Fully deductible for leased office, retail, or warehouse space at fair market value.
- Utilities: Deduct electricity, water, gas, internet, and phone services proportional to business use.
CTAS Guidance: Keep lease agreements and payments documented. Below-market arrangements may limit deductions.
Office Supplies and Equipment
- Supplies: Pens, paper, ink, and other consumables are fully deductible the year purchased.
- Minor Equipment: Small electronics, office chairs, accessories may be expensed under Section 179 (if under limits).
- Larger Assets: Vehicles, machinery, high-cost furniture must be capitalized and depreciated; may qualify for Section 179 or bonus depreciation.
CTAS Guidance: Keep receipts and logs. Determine whether immediate expensing or depreciation is most advantageous.
Business Insurance Premiums
Deductible policies include:
- Liability insurance
- Property insurance
- Workers’ compensation
- Cyber liability insurance
CTAS Guidance: Life or disability insurance may not be deductible. Verify each policy’s eligibility based on your business.
Employee Salaries, Wages, and Benefits
- Salaries, wages, bonuses, and employer contributions to health insurance or retirement plans are deductible.
CTAS Guidance:

Payments to Independent Contractors

- Bonus Depreciation: 40% for 2025 on eligible assets.
Smaller assets (<$2,500) are generally deductible immediately.
CTAS Guidance: Evaluate which method provides the greatest benefit; consult a tax professional.
Business Loan Interest Deduction
Deduct interest on loans, lines of credit, or credit cards used exclusively for business.
