Smart business owners know that legitimate tax deductions can significantly lower their taxable income—but many overlook valuable write-offs simply because they don’t know they exist. The IRS allows deductions for many ordinary business expenses, and missing them means leaving money on the table.
Here’s a list of often-overlooked tax deductions that could save your small business thousands this year.
1. Home Office Deduction (Simplified or Regular Method)
If you work from home, you may qualify for this deduction—even if you’re not a sole proprietor.
Simplified Option:

Regular Method:
- Calculate actual expenses (mortgage interest, rent, utilities, insurance, repairs) based on the percentage of your home used for business.
Key Requirement: The space must be used exclusively and regularly for business.
2. Vehicle Expenses (Standard Mileage vs. Actual Costs)
If you use your car for business, track these deductions:
Standard Mileage Rate (2024):
- 67 cents per mile (business use)
Actual Expense Method:
- Gas, oil changes, repairs, insurance, depreciation
- Pro-rated based on business vs. personal use
Tip: Use a mileage tracker app (like MileIQ or QuickBooks Self-Employed) for accurate records.
3. Startup Costs (Up to $5,000 Deduction)
