Tax Planning Strategies for Small Business Owners
Tax Strategy · 2026-01-28 · 8 min
Tax planning is not about aggressive loopholes. It is about timing income and expenses, choosing the right entity structure, and maximizing legitimate deductions throughout the year.
The most powerful tax planning strategy is also the simplest: defer income and accelerate deductions. If you expect to be in the same or lower tax bracket next year, delay invoicing until January and make deductible purchases in December. This delays the tax on that income by a full year and brings the deduction forward.
Entity structure has a massive impact on tax liability. Sole proprietors pay self-employment tax on all business income. S-Corp owners can pay themselves a reasonable salary and take the rest as distributions, which are not subject to self-employment tax. The breakeven is typically around $50,000-$70,000 in net business income — below that, the administrative cost of an S-Corp is not worth it.
Retirement contributions are the single largest legal tax shelter for small business owners. A SEP-IRA allows contributions up to 25% of net self-employment income. A Solo 401(k) allows even higher contributions with both employee and employer components. These contributions reduce your taxable income dollar-for-dollar.
The QBI (Qualified Business Income) deduction allows eligible business owners to deduct up to 20% of qualified business income. The rules are complex and phase out at higher income levels, but for most small businesses earning under $182,100 (single) or $364,200 (married), this is an automatic 20% reduction in taxable business income.
