How to Account for HSA of Owners on W2: A Comprehensive Guide

Understanding how to account for Health Savings Accounts (HSAs) of owners on W2 forms is crucial for small business owners and individuals who have such accounts. An HSA is a tax-advantaged medical savings account available to individuals who are enrolled in a high-deductible health plan (HDHP). Properly reporting HSA contributions for owners on W2 forms ensures compliance with tax regulations and accurate documentation of health savings.

When it comes to owners of small businesses, there are specific considerations to keep in mind:

  • Owners who are also employees of their businesses can contribute to their own HSAs as individuals.
  • Employer contributions to an owner's HSA are considered employer contributions, not employee contributions, and should be reported accordingly.
  • Contributions made by owners to their HSAs are tax-deductible for the business and excluded from the owner's taxable income.

Here are some key steps to account for HSA of owners on W2 forms:

  1. Obtain accurate records of HSA contributions made by the owner and the business.
  2. Report employer contributions to the owner's HSA in Box 12 of Form W-2 using Code W.
  3. Include the total amount of HSA contributions (both employee and employer) in Box 12 to reflect the overall HSA funding.
  4. Ensure that the owner's total HSA contributions are accurately reported on their personal tax return.
  5. Consult a tax professional or accountant for guidance on reporting HSA contributions for owners, especially in complex ownership structures.

By following these guidelines, owners and small business operators can effectively account for HSAs on W2 forms and stay compliant with tax regulations.


Understanding how to efficiently account for Health Savings Accounts (HSAs) of owners on W2 forms is essential for small business owners. An HSA is not just a savings tool; it's a tax-advantaged medical savings account that allows you to set aside money for healthcare expenses if you’re enrolled in a high-deductible health plan (HDHP).
