How To Add Health Insurance To S-Corp 2%+ Owner W-2 In Gusto

As anyone who’s worked with me — clients, team members, colleagues, vendors — knows, I adore Gusto Payroll. They truly changed my life for the better (not to mention the lives of thousands of small business owners) when they decided to create a tech-forward payroll company that seamlessly syncs with QuickBooks Online.

(Note: our affiliate link will earn you a $100 gift card after you run your first payroll — or up to $500 if you are an accountant or bookkeeper who signs up your own clients. We may earn a commission as well — win-win! For our own clients, we offer a 15% discount in lieu of referral fees.)

I have explained the importance in prior blog posts of making sure that S-Corp medical premiums are properly tracked and reported in QuickBooks and on the W-2 forms for shareholder-employees. The IRS has driven this point home repeatedly, and even has a page devoted to some issues that arise specific to owners of 2% or more of an S-Corp who perform services for the company.

With so many of our own clients using Gusto, I wanted to share how to properly report S-Corp medical insurance premiums, and decided to make the information available to the public as well.

Much of the following information was collected from the Gusto Help section — which is freely available to the public — but as their dynamic support site changes structure and organization frequently, it seemed like collecting the various instructions into one area would be helpful.

Setting up benefits for S-Corp 2% shareholder-employees

For S-Corps, the IRS requires that health insurance premiums paid by the company to employees with a 2% or greater ownership be reported as wages (not pre-tax benefits), and included on their W-2s in Box 1, but not Boxes 3 or 5.

(This means that the total will be taxable for income taxes but not payroll taxes, and once the self-employed health insurance deduction is taken on the personal return, the wages and deduction net to zero — so in effect the corporation will have taken the deduction for the health insurance. More in this blog post and from the IRS here.)

Note: If your company’s benefits are provided through Gusto, they will manage this reporting for S-Corp owners automatically, as long as they are marked as a 2% shareholder in Gusto (under “Employment Details” in the shareholder-employee’s info in the “People” section). 

However, if you offer benefits outside of Gusto (and use Gusto for payroll), then follow these steps to set up benefits for 2% shareholder employees:

  1. Sign in to your Gusto admin account.
  2. Go to the People section and select Team members.
  3. Click on the employee’s name.
  4. Under Employment Details, make sure the employee is designated as a 2% Shareholder.
  5. Under Benefits, click Add Benefit.
  6. Next to Select a Benefit, select “Create New Benefit” from the drop down menu.
  7. Enter a Benefit Name.
  8. Next to Benefit Type, select Medical, Dental, or Vision.
  9. You will have the option to enter a Company Contribution Per Pay Period or Employee Deduction Per Pay Period. (For S-Corp shareholder-employees, this will usually be a company contribution, but check how your plan is set up.)
  10. Company contributions: Taxable at the employee level only, for both federal and state income tax.
  11. Employee deductions: Fully taxable as wages at both the employee and employer level.
  12. Click Save.

As long as the entity is set up in Gusto as an S-Corp and the shareholder-employees that own 2% or more of the company are marked as such under Employee Details, the health insurance premium benefit should be added to Box 1, but not Boxes 3 or 5. You should review your draft W-2 at or shortly after year-end to make sure it is accurate, and contact Gusto immediately if there are issues so they can correct them before the final W-2 is issued and filed with the IRS and SSA.

FAQs about 2% shareholders:

Q: Which benefits must be taxed as wages for 2%+ shareholders?

A: Medical, Dental, Vision, HSAs, and more must be taxed as wages. Refer to Publication 15-B to view all a full list of benefits that are treated as wages. 

Q: What if a 2%+ shareholder status changes part way through the year?

A: Change the 2%+ shareholder status in the employee’s account. Employees who are 2%+ shareholders at any point during the year must be taxed as such for the entire year.

Q: What happens if you need to update an employee’s 2%+ shareholder status mid-or-end year, and they have already received pre-tax benefit deductions this calendar year?

A: If your company withheld health insurance premiums rather than having them processed as 2%+ shareholder — contact Gusto Support, as their team will need to assist within adjusting the benefits, since there are tax implications.
