Maximizing the Qualified Business Income (QBI) Deduction

One of the most valuable tax breaks for self-employed people often goes unclaimed: the Qualified Business Income (QBI) deduction under Section 199A. If you have qualified business income from a pass-through business (sole proprietorship, partnership, S-corp, or LLC), you may deduct up to 20% of that income from your taxable income.

For 2025, the full deduction is available for income below approximately $197,300 (single) or $394,600 (married filing jointly). Above those thresholds, rules get more complex, particularly for “specified service trades or businesses” (SSTBs) like law, health, consulting, and financial services.

This deduction doesn’t require itemizing and directly reduces your taxable income — potentially saving a 24% bracket taxpayer thousands of dollars. Don’t miss it.

Retirement Accounts: The Biggest Self-Employed Tax Lever

Retirement contributions are among the most powerful deductions available to self-employed people:

  • SEP-IRA: Up to 25% of net self-employment income (after SE tax deduction), maximum $70,000 in 2025. Simple to set up, easy to use.
  • Solo 401(k): Up to $23,500 as the “employee” contribution + 25% as the “employer” contribution, total capped at $70,000. Higher contributions possible for those 50+ (catch-up: $7,500 more).
  • SIMPLE IRA: Up to $16,500 employee + 2% employer match or 3% non-elective contribution
  • Traditional IRA: Up to $7,000 ($8,000 if 50+), with deductibility phased out at higher incomes if covered by a workplace plan

You can generally contribute to a SEP-IRA or traditional IRA up to the tax filing deadline (April 15, plus extensions). Solo 401(k) plans must be established by December 31 of the tax year, though contributions can be made until the filing deadline.

Business Expenses Often Overlooked

Beyond the obvious categories, self-employed people frequently miss these legitimate deductions:

  • Bank fees and merchant processing fees: Business bank account fees, PayPal, Stripe, and Square processing fees
  • Professional memberships: Industry associations, trade groups, professional societies
  • Business gifts: Up to $25 per recipient per year
  • Subscriptions: Business-related magazines, newspapers, software tools, and online services
  • Phone: The business-use percentage of your cell phone bill (if you use it for work, which most self-employed people do)
  • Internet: Business-use percentage of your home internet
  • Continuing education: Courses, books, certifications, workshops that maintain or improve skills required for your work
  • Starting costs: If you started your business this year, up to $5,000 in startup costs can be deducted immediately (rest amortized over 180 months)

Quarterly Estimated Taxes: A Deduction You Can Reduce

Self-employed people pay income tax and self-employment tax in quarterly installments. While quarterly payments themselves aren’t a deduction, half of your self-employment tax IS deductible on your Form 1040. This is automatically calculated and reduces your AGI — don’t skip it.

Additionally, your self-employed health insurance premiums deduct dollar-for-dollar against your income (not subject to the 7.5% floor), and your HSA contributions up to $4,300 (individual) or $8,550 (family) are fully deductible.

Bottom Line

Self-employed individuals have more deductions available than most W-2 employees — but only if they claim them. The biggest opportunities: QBI deduction (up to 20% of net income), retirement account contributions (up to $70,000), home office, vehicle, and health insurance premiums. Keep organized records throughout the year and you’ll be well-positioned for tax season.
