2026 S Corp Tax Savings Calculator

Why the S Corp Strategy Still Works in 2026

Under the One Big Beautiful Bill Act (OBBBA) of 2026, the core mechanics of the S Corp tax strategy are unchanged and arguably stronger than ever. The OBBBA made the 20% Qualified Business Income (QBI) deduction permanent — a key benefit that applies directly to S Corp distributions. Combined with the 2026 Social Security wage base of $184,500, business owners who split income between a W-2 salary and pass-through distributions can save thousands in FICA taxes annually.

For context: a sole proprietor pays 15.3% FICA (self-employment tax) on 92.35% of their entire net profit. An S Corp owner only pays that 15.3% on their W-2 salary. Every dollar of profit taken as a distribution skips FICA entirely — that is the strategy.

The "Reasonable Salary" Requirement

The IRS is not naive. They require that S Corp owner-employees pay themselves a reasonable salary — defined as what you would pay a third-party employee to perform the same services. There is no magic number, but the IRS audits aggressively when salary falls below 30–40% of net profit.

The 60/40 Rule is the most widely used guideline: pay yourself 60% of net profit as salary and take 40% as a distribution. This is conservative enough to pass IRS scrutiny while still generating meaningful FICA savings. Our calculator pre-fills this ratio automatically and warns you if your proposed salary falls into high-audit-risk territory.

The 20% QBI Deduction: The Hidden Bonus

Thanks to the OBBBA making QBI permanent, S Corp owners receive a second major tax benefit: the ability to deduct 20% of their qualified business income (distributions) before calculating ordinary income tax. Because W-2 wages are not eligible for the QBI deduction, this creates another incentive to carefully balance salary vs. distribution — you want enough salary to satisfy the IRS, but not so much that you lose the full QBI benefit on your distributions.

State-Specific Considerations

Not all states treat S Corps the same way. Most states follow the federal pass-through treatment, but several impose additional taxes:

• California: Imposes a 1.5% S Corp Franchise Tax on net income (minimum $800/year), in addition to personal income tax on distributions.
• New Hampshire: Has a Business Profits Tax of 7.5% that applies to S Corp income, even though NH has no personal income tax.
• Tennessee & Texas: Both impose franchise/excise taxes on S Corp gross receipts or business value.

Our calculator accounts for these state-level S Corp taxes automatically. Always consult a CPA for your specific situation.

When Does an S Corp NOT Make Sense?

The S Corp strategy has real costs: payroll setup, quarterly payroll tax filings, a separate business tax return (Form 1120-S), and state registration fees. These compliance costs typically range from $1,500 to $3,000 per year. If your FICA savings don't exceed these costs, the election isn't worth it. As a rule of thumb, the S Corp election becomes advantageous when net profit exceeds approximately $80,000 per year.
