Key Takeaway: Many LLC owners miss out on legitimate tax deductions each year. This guide helps you identify and claim commonly overlooked deductions.
1. The Qualified Business Income (QBI) Deduction
Also known as the Section 199A deduction, this allows eligible LLC owners to deduct up to 20% of their qualified business income from their taxable income. This is one of the largest deductions available to small business owners, yet many miss it.
How to Claim It
- • Ensure your LLC is taxed as a pass-through entity (not a C-Corp)
- • Calculate your qualified business income (total income minus deductible expenses)
- • Use IRS Form 8995 for simple calculations or Form 8995-A for complex situations
- • Keep detailed records of all business income and expenses
💡 Pro Tip
If your taxable income is under $191,950 (single) or $383,900 (married filing jointly) for 2025, you'll likely qualify for the full 20% deduction regardless of your business type.
2. Home Office Deduction
If you use part of your home exclusively and regularly for business, you can deduct a portion of your home expenses. This includes rent/mortgage interest, utilities, insurance, and maintenance.
Two Methods to Choose From:
Simplified Method
$5 per square foot of home office space, up to 300 square feet
Max: $1,500/year
Regular Method
Calculate actual expenses × (home office sq ft ÷ total home sq ft)
Typically higher deduction
3. Startup and Organizational Costs
You can deduct up to $5,000 in startup costs and $5,000 in organizational costs in your first year of business. Costs above these amounts can be amortized over 15 years.
What Qualifies as Startup Costs:
- Market research and analysis
- Advertising for business opening
- Employee training
- Travel costs for securing clients
- Professional fees (legal, accounting)
- State filing and registration fees
4. Vehicle Expenses
If you use your vehicle for business purposes, you can deduct those expenses. The IRS offers two methods: standard mileage rate or actual expenses.

Important: Keep a detailed mileage log including date, destination, purpose, and miles driven. Apps like MileIQ can automate this.
5. Health Insurance Premiums
Self-employed LLC owners can deduct 100% of health insurance premiums paid for themselves, their spouse, and dependents. This is an “above-the-line” deduction, meaning it reduces your adjusted gross income.
Requirements to Claim:
- 1Your business must show a profit (can't deduct more than your business income)
- 2You cannot be eligible for employer-subsidized health insurance through your spouse's job
- 3The insurance plan must be established under your business (not purchased individually)
