Cap table export and payroll equity settlement calculation spreadsheet — "Underwithholding payroll taxes on RSU vesting events resulting in IRS penalties"
Why the manual spreadsheet breaks financial controls and how a deterministic workflow replaces it.
RSU vest events are exported from the cap table and multiplied by a price in a payroll sheet, so withholding is computed after the vest and often at the wrong FMV.
Payroll underwithholds on the vest, the employee is surprised at filing, and the company is assessed for the shortfall.
Cap-table webhook that posts each vest to payroll with share count and FMV on the vest date and withholds before the next pay run.
Withholding assertion: a vest cannot settle unless payroll has computed tax on the vest-date FMV and the amount is included in the next locked pay run.
Three-stage comparison between manual workbook reconciliation and automated rule-based execution.
Cap-table exports multiplied by a price after the vest has already occurred.
Withholding misses the vest-date FMV and the next locked pay run.
Each vest arrives with share count and FMV and withholds in the next pay run.
