Self-employed? An S-Corp election could slash your self-employment taxes in 2026, and here's what smart business owners are doing today

Tax planning is easier to fix in October than in April. For small business owners, several 2026 rules change the value of deductions, retirement contributions and business purchases. The biggest opportunities often depend on decisions made before the tax year closes. Business structure is one of them. The distinction can affect payroll and self-employment taxes, although the owner must still pay reasonable compensation and meet IRS requirements.

The business structure can matter more than another deduction

An S-Corp election is not a universal tax shortcut. It works differently depending on profit, payroll costs, administrative expenses and the owner's circumstances. For a profitable business, though, separating salary from eligible distributions can change how much income is exposed to employment taxes.

The timing also matters. Changing an entity's tax treatment is not something to leave until the filing deadline. Owners considering a restructuring should speak with a tax professional well before year-end and determine whether the election actually fits the business.


The permanent 20% Qualified Business Income deduction adds another layer. Eligible owners of pass-through businesses can generally deduct up to 20% of qualified business income, subject to the rules and limitations that apply to their situation. For 2026, the material provided also notes a new $400 minimum deduction for taxpayers with at least $1,000 of QBI.

That makes the business structure question broader than simply choosing between an LLC and an S corporation. The tax result depends on how the entity is taxed, how much the business earns and how the owner is paid.

Bigger deductions make equipment purchases more important

Capital spending can become a tax decision as well as a business decision. Section 179 allows qualifying businesses to immediately expense up to $2.56 million of property placed in service in 2026, with the deduction beginning to phase out after $4.09 million in total qualifying purchases.

That does not mean a business should buy equipment simply to create a deduction. Spending $1 to save a portion of that dollar in taxes is still spending money. The better question is whether the purchase was already useful to the business and whether putting it into service before year-end improves the tax treatment.

The same thinking applies to smaller purchases. The de minimis safe harbor can allow eligible businesses to expense certain low-cost items rather than tracking them as long-term assets.

Retirement and employee benefits can lower taxes without wasting the money

Tax planning is not limited to deductions that disappear after filing. Retirement and employee benefits can shift money toward expenses that support the business and its workers.

For 2026, the supplied figures put the 401(k) employee contribution limit at $24,500, while SIMPLE IRA contributions can reach $17,000. SECURE 2.0 also changes catch-up contributions for workers ages 60 through 63.

Health benefits offer another route. The 2026 HSA limits rise to $4,400 for self-only coverage and $8,750 for family coverage. A health FSA can allow up to $3,400, while the dependent-care FSA limit reaches $7,500 per household.

An accountable plan can also be useful. Properly documented reimbursements for qualifying business expenses can generally remain tax-free to employees while providing a deduction to the business. Mileage, travel, phone use and certain home-office costs can fall into this category when the IRS requirements are met.

Year-end planning is really about timing

Some tax decisions come down to when income and expenses are recognized. A cash-basis business may have more flexibility to control the timing of certain receipts and payments, while accrual-basis businesses face different recognition rules.

Deferring income into 2027 can reduce 2026 taxable income in situations where the rules permit it and a lower future tax bill is expected. The constructive receipt rule matters here: a taxpayer generally cannot simply refuse money that is already available and treat it as though it does not exist.

The same calendar matters for bonuses, equipment and other expenses. Cash-basis businesses generally need qualifying expenses paid by year-end, while accrual-basis businesses may have additional rules for liabilities paid after the close of the year.

That is why a tax review should happen before December 31, not after the books are closed. A business owner who waits until filing season may still claim legitimate deductions, but some planning opportunities will already have passed.
