Historical tax rates need to remain explainable even when their records are consolidated.
A clean target model can still fail if effective dates and source evidence do not survive the move.
Who you’d be doing this for
“A wrong rate doesn’t stay a data problem once payroll is submitted.”
Viktor Gheorghiu · Finance Operations Manager
Runs payroll for a multi-jurisdiction construction company with shifting local tax obligations.
What is at stake
Readiness checks found effective-date conflicts in 0.27% of active tax-rate histories. You have to weigh cutover timing against the evidence needed to trust every active rate.
Why it isn’t already fixed
Every obvious fix costs something else. That’s the part you’d have to decide.
- cutover speed vs verified rate accuracy
- automation scale vs human validation
- model consolidation vs historical explainability
- filing continuity vs irreversible change
