Software: Each recipient form generated for an IRIS CSV filing file counts toward your license allowance; IRS portal file limits are separate. See counting examples. Managed filing: The posted $300 flat-fee tiers on our e-filing pricing page apply to eligible 1099-NEC returns; other form types are quoted individually.

FORM 3921

Built for exercise of an incentive stock option under section 422(b)

For corporations whose employees exercise incentive stock options. Capture grant and exercise details per option exercise; annual compensation totals alone are not sufficient.

Check these 3921 fields

  • Employee and corporation identity
  • Grant and exercise dates
  • Exercise price and fair-market value per share

Example: Incentive stock option exercise

An employee exercises incentive stock options awarded by a corporation. The company reports details of the exercise, including grant date, exercise date, share counts and per-share values.

Form-specific check: An ISO grant by itself is not the same event as exercise, and a later stock sale can have separate reporting. Check exercise price and fair market value per share on the exercise date.

Before importing: Reconcile the option-plan exercise file to payroll/equity administration and employee identifiers.

The IRS portal is free

Prepare your filing data with the software, then submit an eligible CSV through the free IRS IRIS Taxpayer Portal using your own IRIS account. The IRS does not charge a portal filing fee.

FORM 3921 WINDOWS SOFTWARE

A practical Form 3921 software workflow for incentive stock option exercises

Form 3921 software is designed for corporations and equity-compensation administrators. Instead of manually building every return from scratch, work from employee incentive stock option exercise data, review the information that matters for this form, and prepare supported IRS IRIS upload files on your Windows PC.

01 · SOURCE RECORDS

Start with your existing data

Collect employee incentive stock option exercise data. Reconcile the figures to the account, transaction or payer systems that produced them before beginning the filing process.

02 · FORM-SPECIFIC REVIEW

Check Form 3921 fields

Pay particular attention to grant, exercise dates and fair-market value per share. Other fields may be required depending on the tax year and the specific transactions being reported.

03 · WINDOWS PREPARATION

Import, inspect and correct

Use supported Excel or CSV imports, inspect recipient information, and address reported validation issues before generating final files. Your working records stay local during software preparation.

04 · IRS PORTAL FILING

Generate the supported IRIS output

Create the IRS IRIS Taxpayer Portal CSV output supported for Form 3921. Upload it using your authorized IRS access and check the IRS result; buying the Windows license does not itself transmit returns.

Before you purchase Form 3921 software

Make sure your filing year and records are supported, especially if you have special transactions or need to file corrections. Try the application with sample data first, and verify that its output matches your requirements.
