Compliance requirements for 2% shareholder-employees of an S corporation
The tax law treats an S corporation shareholder who owns more than 2% differently from other employees when it comes to fringe benefits. Many benefits that are tax-free for employees are taxable for them, and the S corporation must report them correctly.
Prepared by Prem Tax and Accounting Corp. Last checked against official sources on October 21, 2026.
Who is a 2% shareholder
A "more-than-2%" shareholder is a person who owns, on any day during the S corporation's tax year, more than 2% of its outstanding stock, or stock with more than 2% of the total combined voting power. Under section 318, stock owned by certain family members and entities can be counted as yours.
Why they are treated differently
For income tax rules on fringe benefits, an S corporation is treated like a partnership and a more-than-2% shareholder is treated like a partner (section 1372 and Revenue Ruling 91-26). A partner is not an employee for fringe benefit purposes. So benefits that employees can receive tax-free are generally taxable wages for the shareholder, reported in Box 1 of Form W-2. The shareholder is still an employee for payroll tax purposes.
What changes
| Benefit | Treatment for a more-than-2% shareholder-employee |
|---|---|
| Health and accident insurance paid by the S corporation | Included in Box 1 wages and subject to income tax withholding. Not subject to Social Security, Medicare or FUTA tax if provided under a plan for employees. The shareholder may deduct it on the personal return. See health insurance. |
| Group-term life insurance | The usual tax-free $50,000 of coverage does not apply to a 2% shareholder. |
| Meals and lodging on the business premises for the employer's convenience | The usual exclusion does not apply. |
| Qualified transportation (commuting) benefits | The usual exclusion does not apply. |
| Achievement awards and adoption assistance | The usual exclusion does not apply. |
| Cafeteria plan and health flexible spending arrangement (FSA) | Not available: a 2% shareholder is not treated as an employee for these. |
| Health reimbursement arrangement (HRA) and QSEHRA | Not available to a 2% shareholder-employee. |
| Health savings account (HSA) | No pre-tax salary-reduction contributions. Employer contributions are treated as distributions or guaranteed-payment-type amounts, depending on the facts. |
Benefits that are not fringe benefits at all, such as reimbursing real business expenses under an accountable plan, are not affected. Check each benefit before you offer it.
How the S corporation reports
- Fringe benefits for a more-than-2% shareholder-employee go on line 7 (officer compensation) or line 8 of Form 1120-S, or on Form 1125-E, not on line 18. Line 18 is for employees who own 2% or less.
- They are reported as wages in Box 1 of the shareholder's Form W-2.
- Health insurance premiums are not included in Boxes 3 and 5 (Social Security and Medicare wages) when provided under a plan for employees, and the IRS instructions for Form 1120-S also ask for the amount as an information item in Box 14.
- Form 1125-E (compensation of officers) is required when total receipts are $500,000 or more.
- The shareholder reports the amounts as income and, for health insurance, may claim the deduction on Schedule 1 (Form 1040), line 17.
Compliance checklist
Know the ownership
List every shareholder and their percentage on each day of the year, including family attribution.
Check before you offer a benefit
Ask whether the benefit is tax-free for a 2% shareholder. If not, put it through payroll as taxable.
Set up payroll correctly
Health premiums are in Box 1 but not Boxes 3 and 5. Ask your payroll provider to code them as "S corporation 2% shareholder."
Report on the right line
Line 7 or 8 (or Form 1125-E) for more-than-2% shareholders, line 18 for others.
Avoid plans that do not work
Do not enroll a 2% shareholder in a cafeteria plan, FSA, HRA or QSEHRA.
Keep the records
Premium statements, payroll reports, basis records (Form 7203) and compensation documentation.
Review before W-2s go out
Check the shareholder's Form W-2 before the January 31 deadline.
Common questions
Does my spouse's stock count toward the 2%?
It can. Stock owned by certain family members (such as a spouse, children, grandchildren and parents) can be treated as yours under the section 318 attribution rules, and so can stock held through entities.
What if I own exactly 2%?
The special rules apply to those who own more than 2%. An employee who owns 2% or less is treated like other employees, and the fringe benefits are reported on line 18 of Form 1120-S.
Do these rules apply to a C corporation?
No. They apply to S corporations. An LLC that elects to be taxed as an S corporation is covered.
Is a 2% shareholder still an employee for payroll?
Yes. For wages and payroll tax purposes the shareholder-employee remains an employee. The partner treatment applies to the income tax rules for fringe benefits.
Can I become a 2% shareholder for one day?
The test is whether you own more than 2% on any day of the tax year. Check the ownership on every day of the year, including sales and gifts of shares during the year.
