2025 Incentive Stock Options and ESPP Reporting Deadlines

Annual Reporting on ISO/ESPP Transactions

The IRS issued final regulations in 2009 under Section 6039 of the Internal Revenue Code (the “Code”) that require employers to annually furnish each employee who exercised incentive stock options (“ISOs”) or sold or otherwise transferred shares acquired under an employee stock purchase plan (“ESPP”) during a year with a detailed information statement by January 31 of the following year. In addition, employers must generally file an information return with the IRS by February 28 of the following year, or by March 31 for employers filing electronically. These due dates are delayed until the next business day if they otherwise fall on a weekend.

Information Statements to Employees for 2025 ISO/ESPP Transactions

If in 2025 an employee exercised an ISO (i.e. a stock option described in Section 422 of the Code), the Employer must provide the employee with a written information statement by February 2, 2026 (since January 31, 2026 is a Saturday). Form 3921 should be used for this purpose (click on these two IRS links for additional information Form 3921 About Form 3921). However, a qualifying substitute form may also be used so long as it contains the required information. Only one transaction can be reported on a Form 3921. In other words, an employee will receive more than one Form 3921 from his/her employer for a calendar year if the employee effected more than one ISO exercise in such year.

If in 2025 legal title to stock purchased under an ESPP (i.e. a plan described in Section 423 of the Code) was transferred from the employee to a third party, and such transfer was the first transfer of such shares, the employer must provide the employee with a written information statement by February 2, 2026 (since January 31, 2026 is a Saturday). Form 3922 or a qualifying substitute form may be used (click on these two IRS links for additional information Form 3922 About Form 3922). Only one transaction can be reported on a Form 3922 or in other words, an employee may receive more than one Form 3922 from his/her employer for a calendar year.

Information Reporting to the IRS

In addition, employers must file an information return with the IRS by March 2, 2026 (since February 28, 2026 is a Saturday) or by March 31, 2026 for employers filing electronically. The information returns must be filed on Form 3921 for ISO transactions and Form 3922 for ESPP transfers. In other words, unlike for the employee information statements, no substitute form can be used for the information returns filed with the IRS.

Please note that the Forms 3921/3922 that are filed with the IRS must be scannable. Employers can order the official IRS forms from the IRS, either by calling 1-800-TAX-FORM (1-800-829-3676) or via online and the IRS will mail the employers the scannable forms and other products. Employers filing paper copies must also include IRS Form 1096. Employers filing electronically must have a Transmitter Control Code (see here for application process). Additionally, employers with ten or more information returns must file electronically. 

The failure to timely furnish the information statements, or timely file the information returns, can result in penalties to the employer including fines for each deficient statement or return.

Keep in mind that other reporting obligations may arise upon the disposition of stock acquired under an ISO or an ESPP, such as including the employee’s income from the disposition of stock on Form W-2.

Employers should review their administration of any 2025 ISO and ESPP transactions in order to ensure that they will be able to timely prepare and file the requisite reports.
