Year-end Tax Planning for S-Corporation Owners

Don’t lose valuable deductions or incur additional costs.

Special Reporting Required: The IRS requires special reporting for fringe benefits for S-Corporation owners who own more than 2% of the business.

What you need to do by December 10th: If you use a payroll service, you need to contact them and report this insurance, HSA, and auto information in early December in order to have it included on your 2018 W-2. Avoid costly amended W-2’s and payroll returns.

Health Insurance and HSA Contributions

In order to deduct the cost of health insurance premiums paid by the business on behalf of you and your family you must do the following:

  • Compute the amount of premium paid by the business on behalf of each shareholder for the preceding 12 month period. You can use actual premiums paid for January through November and estimate the December amount if necessary.
  • Insurance Premium to track includes:
    • Medical
    • Long-Term Care
    • Medicare premiums paid

This amount must be reported in Box 1 and Box 14 of the W-2. It is not subject to social security or Medicare tax.

  • HSA - employer contributions for applicable shareholder-employees must be reported in Box 1 and Box 14 of the W-2. HSA contributions are not subject to social security or Medicare tax.

Personal use of Company Owned Autos

Compute the value of the personal use of company autos and include this in Box 1, 3, and 5 of your W-2. This fringe benefit is subject to social security and Medicare tax.

Act Now

Failure to properly report these fringe benefits may result in the loss of these business deductions or additional costs to correct W-2s and payroll reports.

The application of these rules can be complex. Please contact Shannon & Associates if you need assistance or have questions about this important year-end reporting.
