Self-employment tax is often the single largest tax burden on profitable small business owners — and the one most consistently overlooked in tax planning. At 15.3% on net self-employment income up to $168,600 (and 2.9% above that), SE tax frequently exceeds the income tax liability of profitable sole proprietors and single-member LLC owners.
The good news: it is among the most reducible taxes available, through legal, well-established strategies that the IRS explicitly anticipates. FJ & Associates, PLLC helps Utah self-employed business owners implement these strategies and keep more of what they earn.

Understanding Self-Employment Tax
Self-employment tax (SE tax) is the self-employed equivalent of FICA taxes — the Social Security and Medicare taxes that employees and employers split. When you’re self-employed, you pay both halves:
- Social Security: 12.4% on net SE income up to $168,600 (2024 wage base)
- Medicare: 2.9% on all net SE income (no cap)
- Additional Medicare Tax: 0.9% on SE income above $200,000 (single) or $250,000 (married)
Half of SE tax is deductible on your federal return — but the net cost to a sole proprietor with $150,000 in business profit is still approximately $21,000 in SE taxes. That’s real money.
Strategy 1 — S-Corporation Election
The most powerful SE tax reduction strategy for most profitable sole proprietors and LLC owners is electing S-Corporation status.
How it works: As an S-Corp owner, you split your business income into two components — a reasonable W-2 salary (subject to FICA/SE tax) and S-Corp distributions (not subject to SE tax). Only the salary portion bears FICA taxes.
Example:
| Item | Amount |
|---|---|
| Business profit | $150,000 |
| Reasonable salary (S-Corp) | $70,000 |
| Distribution | $80,000 |
| FICA on salary | ~$10,710 |
| FICA avoided on distributions | ~$12,240 savings vs. sole proprietor |
Annual savings: $12,000–$20,000 for many profitable Utah businesses. The S-Corp election costs roughly $1,500–$3,000 per year in additional administrative costs (payroll processing, additional state filing) — the ROI is typically 5–10x.

Strategy 2 — Retirement Plan Contributions
Retirement plan contributions reduce your net SE income — the base on which SE tax is calculated — by reducing your adjusted gross income. This produces a two-for-one benefit: lower income tax AND lower SE tax.
Best options for SE tax reduction:
- Solo 401(k): Allows the largest contributions for self-employed individuals — up to $69,000 in 2024. Employee deferral component reduces W-2 income for FICA purposes if structured as an S-Corp
- SEP-IRA: Simpler; contributions up to 25% of net SE income, maximum $69,000. Reduces AGI and SE tax base
- Defined Benefit Plan: For high-income owners, allows contributions of up to $275,000 annually — the most aggressive SE tax reduction available for older, high-earning business owners
Strategy 3 — Maximize Business Deductions
SE tax is calculated on net self-employment income — gross profit minus business expenses. Every legitimate business deduction reduces the SE tax base dollar-for-dollar.
Commonly missed deductions for self-employed business owners:
- Home office deduction — calculated using actual expenses or the simplified method ($5/sq ft up to 300 sq ft)
- Health insurance premiums — 100% deductible for self-employed individuals and S-Corp owners (properly structured)
- Vehicle expenses — actual or standard mileage rate for business use
- Business travel, meals (50%), and entertainment — properly documented
- Professional development — courses, certifications, books, subscriptions related to your business
- Equipment and depreciation — Section 179 and bonus depreciation accelerate these deductions
Strategy 4 — Qualified Business Income (QBI) Deduction
Pass-through business owners may deduct up to 20% of qualified business income from their taxable income under IRC Section 199A. While the QBI deduction doesn’t directly reduce SE tax, it reduces the income tax on business income — complementing the SE tax reduction strategies above.
Key limitations: the deduction phases out for high-income owners of specified service trades or businesses (SSTBs), including accounting, law, health, and consulting. We model QBI interaction with salary levels to find the optimal combination.
Self-Employment Tax FAQs
At what income level does an S-Corp election make sense?
The breakeven point for most Utah businesses is roughly $40,000–$60,000 in annual net profit, when the SE tax savings exceed the additional administrative costs of running an S-Corp (payroll processing, additional state filings). Above $80,000 in profit, the savings are almost always material. We model your specific numbers.
Can I form an S-Corp in the middle of the year?
Yes — but the election is most effective when made at the beginning of the tax year or when the business is first formed. Mid-year elections are possible but prorate the SE tax savings. Contact us to evaluate timing for your specific situation.
Do I still owe SE tax if I have an S-Corp and pay myself a salary?
Yes — on the salary portion only. FICA taxes apply to your W-2 wages just as they would for any employee. The SE tax savings come from the distribution portion, which is not subject to FICA.
What if I can’t afford to pay myself a reasonable salary right now?
If your business income is too low or too variable to support a consistent salary, an S-Corp election may not be the right move yet. We advise on the income threshold at which the election becomes worthwhile and plan the timing accordingly.
