Running a small business in 2026 means navigating a changed tax landscape — new rules, expiring provisions, and fresh opportunities to reduce what you owe. Here are the 10 most impactful moves you can make this year.
1. Max Out the QBI Deduction
The Section 199A Qualified Business Income deduction allows eligible pass-through business owners (sole proprietors, partnerships, S-corps) to deduct up to 20% of qualified business income. With the TCJA extension, this remains in effect for 2026. On $100,000 of QBI, that's a $20,000 deduction — real money.
2. Accelerate Depreciation with Section 179
Section 179 allows you to immediately deduct the full cost of qualifying equipment and software in the year of purchase, rather than depreciating it over years. In 2026, the deduction limit is approximately $1,220,000. Buy that new computer, vehicle, or equipment before year-end.
3. Set Up or Maximize a Retirement Plan
Business owners have access to the most powerful retirement accounts available:
- SEP-IRA: Contribute up to 25% of net self-employment income (max ~$71,000) — contributions are due by your tax filing deadline including extensions
- Solo 401(k): Highest contribution limits — up to $71,000 for 2026 — and allows Roth contributions
- SIMPLE IRA: Great for businesses with employees; lower admin than a 401(k)
4. Hire Family Members Strategically
Paying your spouse or children a reasonable salary for legitimate work shifts income to a lower tax bracket and may avoid payroll taxes in some structures. A sole proprietor who employs their child under 18 doesn't pay FICA taxes on those wages.
5. Review Your Entity Structure
If you're still operating as a sole proprietor or single-member LLC paying self-employment tax on everything, 2026 is the year to model whether an S-Corp election saves you money. Businesses netting over $50,000 consistently should run the numbers.
6. Prepay Deductible Expenses Before Year-End
If you're on the cash basis of accounting, you can accelerate deductions by prepaying expenses in 2026 that relate to early 2027 — rent, insurance premiums, subscriptions, and supplies up to 12 months in advance.
7. Take Advantage of the Home Office Deduction
Remote work is now mainstream. If you have a dedicated space used exclusively for business, the home office deduction can yield $1,500–$5,000+ in additional deductions depending on your home size and actual expenses.
8. Document and Deduct Business Meals
Business meals with clients, prospects, or partners are 50% deductible. For 2026, keep receipts and note: who attended, the business purpose, and the date. Apps like Expensify or Zoho Expense make this easy.
9. Fund an HSA if You Have a High-Deductible Health Plan
Health Savings Account contributions are triple tax-advantaged: deductible going in, grow tax-free, and come out tax-free for medical expenses. For 2026: $4,450 (self-only) or $8,850 (family). Unused funds roll over indefinitely.
10. Schedule a Mid-Year Tax Review
The biggest mistake business owners make is waiting until April to think about taxes. A mid-year review lets you adjust withholding, make estimated payments, time income and expenses, and implement strategies before the year closes.
