5 Commonly Missed Deductions for LLCs (And How to Claim Them)

Learn how pass-through deduction, home office, and startup costs can save you thousands in taxes.

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.

2025 Standard Mileage Rates:

Business Miles67¢ per mile

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:

  • 1
    Your business must show a profit (can't deduct more than your business income)
  • 2
    You cannot be eligible for employer-subsidized health insurance through your spouse's job
  • 3
    The insurance plan must be established under your business (not purchased individually)

Potential Tax Savings Example

For an LLC owner in the 24% tax bracket earning $100,000:

  • • QBI Deduction (20%): $4,800 saved
  • • Home Office (300 sq ft): $360 saved
  • • Health Insurance ($8,000/yr): $1,920 saved
  • • Vehicle (10,000 miles): $1,608 saved

Total Potential Savings: $8,688

Next Steps: Don't Leave Money on the Table

  1. 1.Keep meticulous records: Use accounting software like QuickBooks or Xero to track all business expenses throughout the year.
  2. 2.Consult a tax professional: A CPA who specializes in small business taxes can identify additional deductions specific to your situation.
