Engineering payroll allocation sheet and contractor tax credit study — "Substantial tax credit disallowance during IRS exam due to reconstructed contemporaneous logs"
Why the manual spreadsheet breaks financial controls and how a deterministic workflow replaces it.
Qualified research expenses are reconstructed after year end from payroll exports and contractor invoices, so contemporaneous project logs do not exist when the credit study is written.
The IRS exam disallows the credit because time and contractor cost cannot be tied to qualified activities in the period they were incurred.
Engineering activity feed from issue tracker and source control that tags payroll and contractor cost to qualified projects as the work happens.
Contemporaneous assertion: a credit claim line must cite activity records dated in the same period as the wage or invoice, or it is excluded from the study.
Three-stage comparison between manual workbook reconciliation and automated rule-based execution.
Payroll and contractor costs allocated to projects after the books close.
The credit is built from reconstructed allocations and fails the contemporaneous-log test.
Qualified time and cost attach to project activity as the work is done.
Every claimed line cites activity dated in the same period as the wage or invoice.
