The S Corporation Shareholder's Health Insurance Premiums
Mike is a 2% shareholder-employee of an S corporation, ABC Inc. He works full-time and is paid a reasonable salary of $80,000. The S corporation paid $12,000 in health insurance premiums for Mike and his family in 2025. The premiums were not included in Mike's W-2 wages. Mike also received a distribution of $20,000 from the S corporation. The S corporation's net income before considering the health insurance premiums and Mike's salary was $150,000. Mike's marginal tax rate is 32% for ordinary income and 15% for qualified business income (QBI). He wants to minimize his overall tax liability. Assume the S corporation has no other employees and that the health insurance premiums are for a plan established by the S corporation.
1. How should the health insurance premiums be treated for tax purposes, and what is the impact on Mike's W-2 wages and the S corporation's deduction?
Read the worked answer
Under IRC §1372, for a 2% shareholder-employee, the S corporation's payment of health insurance premiums is treated as a distribution to the shareholder, not as wages, unless the premiums are included in the shareholder's W-2 wages. However, to deduct the premiums as a business expense, the S corporation must include the premiums in the shareholder's W-2 wages. The shareholder can then deduct the premiums on their personal return as self-employed health insurance (above-the-line deduction) under IRC §162(l). Therefore, the correct treatment is: The S corporation should include the $12,000 in Mike's W-2 wages (Box 1, 3, and 5). The S corporation deducts the $12,000 as compensation. Mike reports $92,000 in W-2 wages and deducts $12,000 as self-employed health insurance on his Form 1040. The $20,000 distribution is a tax-free return of basis to the extent of basis; any excess is capital gain. Assuming basis is sufficient, it's not taxable. The S corporation's net income after salary and premiums: $150,000 - $80,000 - $12,000 = $58,000. But wait, the salary was $80,000; adding $12,000 makes it $92,000. So net income = $150,000 - $92,000 = $58,000. Mike's share of S corp income is $58,000 (assuming 100% ownership). Mike's QBI deduction: QBI is $58,000, but must reduce by the self-employed health insurance deduction? Actually, the self-employed health insurance deduction is deducted from QBI? Under §199A, the deduction for self-employed health insurance is attributable to the trade or business and reduces QBI. So QBI = $58,000 - $12,000 = $46,000. Then QBI deduction = 20% of $46,000 = $9,200, subject to limitations. Mike's taxable income: W-2 wages $92,000 + S corp income $58,000 - self-employed health insurance $12,000 = $138,000. Then QBI deduction $9,200, so taxable income $128,800. Tax savings from QBI deduction at 32% = $2,944. If the premiums were not included in W-2, the S corp would not deduct them, so net income would be $150,000 - $80,000 = $70,000. Mike's W-2 wages $80,000 + S corp income $70,000 = $150,000, no health insurance deduction. QBI = $70,000, QBI deduction = $14,000, taxable income = $136,000. Compare: with inclusion, taxable income $128,800, tax at 32% = $41,216. Without inclusion, taxable income $136,000, tax at 32% = $43,520. So including in W-2 saves $2,304. But also consider payroll taxes: including in W-2 wages increases Social Security and Medicare taxes? For 2% shareholder, health insurance premiums included in W-2 are subject to FICA? Actually, for 2% shareholders, health insurance premiums are not subject to FICA taxes (Social Security and Medicare) because they are not wages for FICA purposes? Under IRC §3121(a)(2)(B), payments for health insurance are excluded from FICA wages. So no additional payroll tax. Therefore, the optimal treatment is to include the $12,000 in W-2 wages and deduct as self-employed health insurance. This reduces income tax and increases QBI deduction? Wait, it reduces QBI, which reduces QBI deduction, but the net effect is still beneficial because the deduction is at 32% while the QBI deduction loss is at 32% of 20% = 6.4%? Let's compute: Without inclusion: tax = $43,520. With inclusion: tax = $41,216. Savings $2,304. So it's better to include. However, note that the self-employed health insurance deduction is limited to earned income from the business. Mike's earned income is $92,000, so $12,000 is fully deductible. So answer: Include $12,000 in W-2 wages, S corp deducts $12,000, Mike deducts $12,000 above-the-line, QBI is reduced by $12,000, but overall tax savings.
2. Calculate Mike's QBI deduction and total taxable income under the optimal treatment, and compare it to the alternative of not including the premiums in W-2 wages.

Optimal treatment (include in W-2):
- W-2 wages: $80,000 + $12,000 = $92,000
- S corporation ordinary income: $150,000 - $92,000 = $58,000
- Self-employed health insurance deduction: $12,000
- QBI: $58,000 - $12,000 = $46,000 (since the health insurance deduction is attributable to the business)
- QBI deduction: 20% * $46,000 = $9,200 (assuming no limitations; Mike's taxable income before QBI is $92,000 + $58,000 - $12,000 = $138,000, which is below the threshold for 2025? The threshold for 2025 is around $200,000 single, so no limitation. So $9,200 is allowed.)
- Taxable income: $138,000 - $9,200 = $128,800
- Tax at 32%: $41,216 (ignoring other deductions)
Alternative (not include in W-2):
- W-2 wages: $80,000
- S corporation ordinary income: $150,000 - $80,000 = $70,000 (since premiums are not deducted)
- No self-employed health insurance deduction
- QBI: $70,000
- QBI deduction: 20% * $70,000 = $14,000
- Taxable income: $80,000 + $70,000 - $14,000 = $136,000
- Tax at 32%: $43,520
Savings: $43,520 - $41,216 = $2,304. Therefore, the optimal treatment saves $2,304 in federal income tax. Additionally, there is no FICA tax on the premiums for 2% shareholders, so no extra payroll tax. Thus, Mike should include the premiums in W-2 wages.
