Filing of Form 1099-MISC Recipients

Incentive Stock Options – Filing of Form 3921 Recipients
January 31 
IRS
February 28 (paper) or March 31 (electronic)
For any exercise of an incentive stock option  (ISO) or transfer of a share previously purchased pursuant to a tax-qualified employee stock purchase plan (ESPP) where the purchase price paid for the share was (a) less than 100% of the fair market value on the date of grant or (b) not fixed or determinable on the date of grant, the company is required to report the transaction on Form 3921 which is due to the recipient by January 31 of the following year and must be provided to the IRS on paper by February 28 of the following year or electronically by March 31.
Reporting of Stock Option Exercise on an Employee’s W-2 Recipients
January 31
IRS
January 31 (paper & electronic)
If an employee holding a non-qualified stock option exercises his or her option to purchase shares, where the purchase price of the shares (strike price) is less than the fair market value on the date of exercise, the difference between the purchase price and the fair market value of the stock must be included on the employee’s W-2 as compensation income. This must be done (typically by your payroll company) before the end of the year of exercise in order to be properly accounted for as employee compensation. While this generally only applies to non-qualified stock options (rather than ISOs), keep in mind that there are scenarios where, if a holder of an ISO exercises his option to purchase shares and sells those shares in a “disqualifying disposition” a portion of the gain would need to be recognized on his W-2 as compensation. Please discuss with your tax advisor.

The Affordable Care Act created new reporting requirements where certain employers must provide information to the IRS about the health plan coverage they offer to their employees. This applies to small employers with less than 50 full-time-equivalent employees that sponsor a self-insured group health plan or large employers with 50 or more full-time equivalent employees, regardless of whether they offer fully-insured, self-insured or no health insurance plans. Applicable small employers report information on that coverage to the IRS and covered individuals by filing Forms 1094-B and 1095-B. For reporting purposes only, an applicable large employer will use Forms 1094-C and 1095-C. The return and transmittal form must be filed with the IRS on or before the last day of February (March 31 if filed electronically) of the year following the calendar year of coverage. You may obtain an automatic 30-day extension of time to file by completing Form 8809, Application for Extension of Time to File Information Returns, and filing it with the IRS on or before the due date.
