The highest-impact self-employed deductions in 2026 are the Qualified Business Income (QBI) deduction, the home office deduction, the self-employment tax deduction, self-employed health insurance premiums, retirement plan contributions, vehicle and mileage, and ordinary business expenses. Used together, they can lower your taxable income by thousands. Here is how each one works and who qualifies.
Why self-employed deductions matter more than ever
Self-employed workers pay both halves of Social Security and Medicare — the 15.3% self-employment tax — on top of income tax. Deductions are how you claw that back. The rule is simple: an expense is deductible when it is ordinary and necessary for your business. Track everything, keep receipts and a mileage log, and separate business and personal accounts so your records hold up.
1. Qualified Business Income (QBI) deduction — up to 20%
The QBI deduction lets many pass-through owners deduct up to 20% of their qualified business income, subject to income thresholds and business-type limits. It is one of the largest breaks available to sole proprietors, partnerships, and S-corps. Best for: almost every profitable 1099 worker under the income limits.
2. Home office deduction — a percentage of your home costs
If you use part of your home regularly and exclusively for business, you can deduct a share of rent, utilities, and insurance. The simplified method allows $5 per square foot up to 300 square feet ($1,500 max); the regular method can be larger if your actual costs are high. Best for: anyone with a dedicated workspace at home.
3. Half of your self-employment tax
You can deduct 50% of the 15.3% self-employment tax you pay as an above-the-line adjustment, reducing your income tax even if you do not itemize. Best for: every self-employed filer — it is automatic once you calculate SE tax.
4. Self-employed health insurance premiums
If you are not eligible for an employer plan (including a spouse's), you can deduct 100% of your health, dental, and qualifying long-term care premiums for yourself and your family. Best for: freelancers buying their own coverage.
5. Retirement contributions — SEP-IRA and Solo 401(k)
Self-employed retirement plans offer huge deductible contribution room — a SEP-IRA or Solo 401(k) can let you set aside tens of thousands per year, well above a standard IRA. You cut taxes now and build retirement savings. Best for: owners with strong profit who want the largest legal deferral.
6. Vehicle and mileage
Business driving is deductible either by the IRS standard mileage rate (around 70 cents per mile in 2025, adjusted annually) or by actual expenses like gas, insurance, and depreciation. Commuting does not count — keep a contemporaneous mileage log. Best for: anyone who drives for client work, deliveries, or business errands.
7. Everyday business expenses — software, supplies, and meals
Ordinary costs of running your business are deductible: software subscriptions, phone and internet (business share), supplies, professional fees, advertising, and business meals (generally 50%). Best for: every self-employed person — these add up faster than most people expect.
How to choose which deductions to prioritize
Stack the biggest levers first: the QBI deduction and retirement contributions usually move the needle most, followed by the health insurance and home office deductions. Track expenses year-round rather than reconstructing them in April, keep business and personal finances separate, and pay quarterly estimated taxes to avoid penalties. Because thresholds and phase-outs change annually, run your specific numbers with a CPA or tax software before filing.
Can I take the home office deduction if I rent?
Yes. Renters qualify the same as homeowners as long as the space is used regularly and exclusively for business. You deduct a share of rent and utilities, or use the simplified $5-per-square-foot method.
Do I need an LLC to claim these deductions?
No. Sole proprietors filing a Schedule C can claim every deduction here. An LLC or S-corp can add liability protection and, in some cases, payroll-tax savings, but it is not required to write off business expenses.
How much can self-employment deductions save me?
It depends on your income and expenses, but between the QBI deduction, retirement contributions, and everyday write-offs, many self-employed filers reduce taxable income by several thousand dollars or more each year.
