Running an LLC means you’re entitled to a powerful set of tax deductions — but most owners claim fewer than half of them. Here’s what you’re probably missing.
1. Home Office Deduction
If you use a dedicated space in your home exclusively for business, you can deduct a portion of your rent or mortgage, utilities, and internet. The IRS allows either the simplified method ($5 per square foot, up to 300 sq ft) or the actual expense method. Most LLC owners skip this entirely out of fear of an audit — but when documented properly, it’s one of the cleanest deductions available.
2. Vehicle Business Use
Every mile you drive for business — client meetings, supply runs, banking — is deductible. In 2025, the standard mileage rate is 70 cents per mile. Keep a mileage log (apps like MileIQ make this trivial) and you could be looking at thousands of dollars in deductions.
3. Self-Employed Health Insurance
If your LLC doesn’t provide health insurance through an employer plan, you can deduct 100% of health insurance premiums you pay for yourself and your family. This comes directly off your adjusted gross income — not just as an itemized deduction.
4. Retirement Contributions (SEP-IRA or Solo 401k)
LLC owners can contribute up to 25% of net self-employment income to a SEP-IRA, or up to $69,000 annually to a Solo 401(k). This is both a retirement strategy and a tax strategy — contributions reduce your taxable income dollar for dollar.
5. Business Meals (50% Deductible)
Client dinners, team lunches, and meals while traveling for business are 50% deductible. Document the business purpose, who attended, and the date. A simple note in your calendar or expense app is sufficient.
6. Professional Development & Subscriptions
Courses, certifications, books, industry publications, and software subscriptions directly related to your business are fully deductible. This includes accounting software, CRM tools, design platforms — any tool you use to run the business.
7. Startup Costs (If You Launched Recently)
If your LLC launched in the past few years, you can deduct up to $5,000 in startup costs in your first year of business, with the remainder amortized over 15 years. This includes legal fees, marketing research, and pre-launch expenses.
The Bottom Line
Most LLC owners overpay their taxes by $3,000–$8,000 annually simply because they aren’t tracking deductions properly or aren’t working with an advisor who asks the right questions. A 30-minute strategy session can identify exactly what you’re leaving on the table.
