Prepare Form 3921 without retyping every return into a portal.
Form 3921, Exercise of an Incentive Stock Option Under Section 422(b), is commonly used by corporations reporting employee exercises of incentive stock options. 1099ERICH is designed to help organize employee, option grant, exercise, and stock value information in a repeatable desktop workflow.
What the software does
- Imports the required structured CSV or Excel layout for Form 3921.
- Checks imported records for missing or incorrectly formatted information before you create filing files.
- Lets you correct the source spreadsheet and re-import until the validation report is clean.
- Prints recipient copies locally, including masked taxpayer identification numbers where appropriate.
- Creates IRS IRIS CSV upload files in blocks of no more than 250 records for the supported workflow.
Why a dedicated 3921 workflow helps
When you prepare many 3921 returns, a consistent import layout can reduce repetitive typing and make corrections easier to control. Your source file remains on your computer during the normal software workflow, and you upload the final files through your own IRS IRIS access.
