Self-Employed Tax Deductions 2026: The Complete List of What You Can Write Off

Most self-employed people claim 4–5 deductions. The tax code allows 20+. Here's everything you can legally deduct in 2026, with IRC citations and exact dollar limits.

If you're self-employed and filing a Schedule C, you are running a business — and the IRS gives businesses a significant advantage: the ability to deduct ordinary and necessary business expenses before calculating taxable income.

Most self-employed people only claim the obvious ones: home office, mileage, maybe a software subscription. They're leaving $10,000–$40,000 in legitimate deductions on the table every year.

This guide covers every major deduction available to self-employed individuals in 2026, with IRC sections, current dollar limits, and the documentation you need.

1. Self-Employment Tax Deduction (IRC §164(f))

You pay both employer and employee portions of Social Security and Medicare — 15.3% total. You can deduct 50% of your SE tax directly from gross income on Schedule 1.

On $200,000 net income: SE tax ~$24,000 → deduct $12,000 → reduces taxable income to $188,000.

Documentation: Calculated automatically on Schedule SE.

2. Home Office Deduction (IRC §280A)

Deduct expenses for space used regularly and exclusively for business:

Simplified method: $5 × sq ft of office (max 300 sq ft = $1,500)
Actual expense method: (Office sq ft ÷ Total sq ft) × (rent/mortgage interest, utilities, insurance, depreciation)

The actual method almost always wins for homeowners — depreciation alone on a $600,000 Florida home can generate $3,000–$4,000/year.

3. Health Insurance Premiums — 100% Deductible (IRC §162(l))

Deduct 100% of health, dental, and vision premiums for yourself, spouse, and dependents. Applies even without itemizing. A family plan at $10,000/year saves $2,400 in taxes at the 24% bracket.

Key rule: Cannot exceed net self-employment income for the year.

4. Retirement Plan Contributions — Up to $70,000 (IRC §401(k), §408)

SEP-IRA	25% of net income, max $70,000	Simple setup, last-minute contributions

5. QBI Deduction — 20% Off Business Income (IRC §199A)

Deduct up to 20% of net qualified business income. On $200,000 net income: $40,000 deduction → $12,800 in tax savings at 32%.

Deductions Most Self-Employed People Miss

Augusta Rule (IRC §280A(g)): Rent your home to your business up to 14 days/year — you receive tax-free income, business deducts the payment. At South Florida market rates: $5,000–$14,000 tax-free annually.
Hiring your children: Children under 18 pay no SE tax on wages from a parent's sole prop. First $14,600 (2026 standard deduction) is income-tax-free to them.
Merchant processing fees: Every Stripe/PayPal fee is deductible. At $300K revenue and 2.9% processing: $8,700/year in deductible fees.
Start-up cost amortization (IRC §195): Up to $5,000 of start-up costs deductible in Year 1.

What the IRS Wants to See

The standard is "contemporaneous documentation" — records created at the time of the expense:

Receipts or bank/credit card statements
Business purpose for each expense
Who was involved (meals)
Mileage log (date, destination, business purpose, miles)

Best practice: Use a dedicated business credit card. Every statement becomes a near-complete expense record.
