Year-end W-2 compilation workbook and payroll register export — "Corrected W-2c filings after year-end totals fail to match the locked payroll register"
Why the manual spreadsheet breaks financial controls and how a deterministic workflow replaces it.
Annual wage and tax statements are assembled in a year-end workbook from payroll-register exports, then tied out by hand to boxes that do not share a control total.
W-2 and W-2c corrections follow because the statement totals do not equal the locked register for the same employee and year.
Year-end issuance engine that builds each statement from the locked payroll register and withholds transmission until every box ties to that register.
Tie-out assertion: a W-2 cannot transmit unless wage, tax, and withholding boxes equal the locked register for that employee and tax year.
Three-stage comparison between manual workbook reconciliation and automated rule-based execution.
W-2 boxes are filled from exports that do not share a control total.
Corrected W-2c filings follow because statement totals miss the locked register.
Each statement transmits only when every box equals the locked register.
A W-2 cannot transmit unless wage, tax, and withholding boxes equal the locked register.
