Most freelancers and business owners pay more in taxes than they have to. The IRS isn't going to remind you about the tax deductions for self-employed people you're legally entitled to — and every deduction you miss is money you earned that you hand over unnecessarily. If you've been filing your taxes without digging into these write-offs, you're almost certainly overpaying. The good news: this is fixable.
You're leaving money on the table — not because you're doing anything wrong, but because nobody teaches you this stuff. The tax code has real deductions built specifically for self-employed people, and most of them are straightforward to claim. Here are the seven that go unclaimed most often.
1. Home Office Deduction
If you use part of your home exclusively and regularly for business, you can deduct it. That means a dedicated room — not your kitchen table. The IRS offers two methods:
Simplified method: $5 per square foot, up to 300 sq ft ($1,500 max). Easy to calculate and requires minimal documentation.
Actual method: Deduct the percentage of your home used for business applied to rent, utilities, insurance, and mortgage interest. More paperwork, but often a larger deduction.
The key rule: the space must be used only for work. A guest bedroom with a desk doesn't qualify. A dedicated home office does.
2. Health Insurance Premiums
Self-employed people can deduct 100% of health insurance premiums paid for themselves, their spouse, and their dependents — directly from their gross income. This is one of the most valuable self-employment deductions, and one of the most overlooked.
Important caveat: you can't claim this deduction if you were eligible for coverage through a spouse's employer-sponsored plan, even if you didn't enroll. If your spouse's employer offers coverage, check whether you qualify before claiming this one.
3. Self-Employment Tax Deduction
When you're self-employed, you pay both the employer and employee portions of Social Security and Medicare — that's 15.3% of net earnings. It stings. But here's what most people miss: you can deduct 50% of that self-employment tax from your adjusted gross income.
This deduction shows up on Schedule 1, not Schedule C — so it reduces your income tax regardless of whether you itemize. On $60,000 of self-employment income, that's roughly a $4,590 deduction you don't have to do anything extra to earn.
4. Retirement Contributions
This is the biggest lever most self-employed people never pull. You can contribute to a SEP-IRA or Solo 401(k) and deduct every dollar contributed from your taxable income. The contribution limits are generous:
SEP-IRA: Up to 25% of net self-employment income, max $69,000 for 2024.
Solo 401(k): Up to $23,000 in employee contributions + 25% of net earnings as employer contributions — up to the same $69,000 combined cap.
Contributing $15,000 to a SEP-IRA could reduce your federal tax bill by $3,300–$5,550 depending on your bracket — while also growing your retirement savings. It's the only deduction that makes you richer in two ways at once.

Every mile you drive for business — client meetings, supply runs, bank trips — is deductible. The IRS standard mileage rate for 2024 is 67 cents per mile. That adds up fast: 5,000 business miles = $3,350 deduction.
Keep a mileage log (the IRS requires one). Apps like MileIQ or Everlance do this automatically. Commuting from your home to a regular office doesn't count — but if your home office qualifies, any trip away from it for business purposes does.
6. Professional Development & Courses
Books, online courses, workshops, and conferences that maintain or improve skills required in your current business are fully deductible. This is a "tax deductions for self-employed" category that most freelancers and consultants underuse — because it sounds too good to be true.
The rule: it must relate to your current work, not a new career. A copywriter buying a course on advanced persuasion techniques? Deductible. The same copywriter buying a course on becoming a licensed electrician? Not deductible. Keep your receipts and note the business purpose on each one.
7. Software and Subscriptions
Every tool you use to run your business is deductible — accounting software, project management tools, design apps, cloud storage, email marketing platforms, even your website hosting. If it's essential to how you operate, it's a write-off.
Most self-employed people are already paying for these tools but forget to track them at tax time. A simple spreadsheet or expense tracker app keeps this organized throughout the year so you're not scrambling in April.

Don't Do This Alone
The IRS tax code is dense by design — and most self-employed people only learn about missed deductions after they've already filed and paid. Knowing what you're owed matters, but knowing how to claim it correctly (with the right documentation, in the right category, on the right form) is what keeps you out of trouble while keeping more money in your pocket.
If you're serious about cutting your tax bill, start with the deductions above. And if you want a clear, practical guide that walks through every one of them — with examples and checklists — the Tax Savings Playbook is built exactly for that.
