The government doesn’t hate small business owners. The tax code was actually written with you in mind — there are real, legal, substantial ways to keep more of what you earn. The problem isn’t that the deductions don’t exist. The problem is that nobody ever sat down and told you what they were.

Consider this that conversation.

The Rule That Governs Everything

Under IRS rules, a business expense is deductible if it’s both ordinary — common in your industry — and necessary — helpful and appropriate for your business. You don’t need to prove it was absolutely essential. You need to show it was a legitimate business expense, properly documented. That’s the standard. It’s lower than most people think.

Home Office

If part of your home is used regularly and exclusively for business, you can deduct it. Two methods:

Simplified method: $5 per square foot, up to 300 square feet — $1,500 maximum. Easy math, no receipts required beyond the floor plan.

Regular method: Calculate the percentage of your home used for business and apply it to your actual home expenses — mortgage interest, rent, utilities, insurance, repairs. Usually higher. More math. Worth it if your home expenses are substantial. The key word throughout: exclusive. A room that doubles as a guest bedroom doesn’t qualify. A dedicated office that no one else uses does.

Vehicle and Transportation

Business use of your vehicle is deductible. Two options:

Standard mileage rate: The IRS sets this annually. Track every business mile — a mileage log app makes this painless. Client meetings, supply runs, business travel all count. Commuting doesn’t. Ever.

Actual expense method: Deduct the business-use percentage of real car expenses — gas, insurance, maintenance, depreciation. If you drive mostly for business, this usually wins. You pick one method per vehicle per year and stick with it.

Health Insurance Premiums

Self-employed LLC owners can deduct 100% of health, dental, and vision insurance premiums paid for themselves and their family. This is an above-the-line deduction — it reduces your adjusted gross income whether or not you itemize. It’s one of the most underused deductions available to small business owners, and one of the most valuable.

Retirement Contributions — Where Real Money Gets Saved

This is where the tax savings get genuinely significant. Every dollar you put into a qualifying retirement account reduces your taxable income by a dollar. And the limits are far higher than most people know:

• SEP-IRA: Up to 25% of net self-employment income, maximum $69,000 for 2024. One form to set up. No annual filing required.
• Solo 401(k): Up to $69,000 per year ($76,500 if you’re 50+). Includes both employee and employer contributions. More flexibility, slightly more paperwork.

These aren’t just tax deductions. They’re how you build personal wealth through the business. A profitable LLC with a well-funded retirement strategy is doing two things at once: reducing the tax bill this year and building the future simultaneously.

Equipment and Technology — Section 179

Under Section 179, you can deduct the full cost of qualifying equipment and technology in the year you buy it — rather than depreciating it over five or seven years. Computers, phones, office furniture, machinery, software — up to $1,160,000 (adjusted annually). In a growth year when you’re investing in tools and infrastructure, this deduction can be enormous. It’s also how the tax code quietly incentivizes business investment.

The Other Ones That Add Up

Business meals: 50% deductible. Document who you ate with, why, and what it cost. That’s it.

Business insurance: 100% deductible — general liability, E&O, property, cyber, workers’ comp.

Professional services: Legal fees, accounting, bookkeeping, consulting — fully deductible. Yes, including the cost of forming your LLC and the Corp Nation service fee.

Marketing and advertising: Website, ads, social media, trade shows — all fully deductible business expenses.

Education: Courses, books, seminars, coaching — deductible as long as the education maintains or improves skills required in your current business. Not for pivoting into a new career. For getting better at what you already do.

The One That Could Change Everything: QBI

Pass-through business owners may be eligible to deduct up to 20% of qualified business income under Section 199A. The rules are complex — there are income thresholds, phase-outs for certain service businesses, and limitations based on wages paid — but for businesses that qualify, this deduction is substantial. It’s worth a specific conversation with your CPA. Don’t skip it.

The Record-Keeping Rule

Every deduction requires documentation. Receipts, invoices, records — keep them for at least three years, seven for anything involving underreported income. Dedicated business banking and bookkeeping software (QuickBooks, Wave, whatever you use) makes this automatic. It also makes tax season something other than a catastrophe. And it makes audits survivable rather than devastating.
