Corrections

Payroll changes. The record stays intact.

Payroll gets questioned because reality arrives late: a missed timecard, a retro raise, a W-4 change, a garnishment, a prior-provider import, or an agency notice. Runbook treats correction as core payroll, not an afterthought.

The original run stays intact. The new fact creates a traceable delta.

The public rehearsal uses fictional records and simulated receipts. Live payroll, refunds, and amended tax filing are not available.

WhyWhat changedWho approvedProof

The reconciliation failure that shows up at tax time.

A correction that rewrites the run leaves the worker statement, the state filing, and the deposit telling different stories.

10%

Withholding records a tax department could not verify.

New York measured a 10% exception rate for filers whose payroll ran through the largest payroll providers, against 5.7% for employers filing on their own. An exception means the withholding on the worker’s return did not match what the provider reported to the state, or the record was missing data. The report notes that a provider’s error usually surfaces at tax time, not on the paystub.

How a correction stays connected.

The calculation preserves the original record. Completing a correction also requires the right human answers and evidence for each consequence; availability varies by case below.

1

Approved run

The payroll period is sealed with the facts and rules known at approval time.

2

Late fact arrives

A source event records what changed, when it was known, and who supplied it.

3

Replay period

The engine recomputes the affected period under the correct knowledge horizon.

4

Show delta

Runbook shows the exact employee, employer, tax, deduction, and liability difference.

5

Approve carryforward

The delta is proposed for the next run or amendment workflow with human approval.

6

Seal evidence

The correction record travels with payroll reports, notice packets, and the sealed payroll proof (Quittance).

Try it in the public demo

Follow a late fact through the work it creates.

Explore a fictional opening-wage correction from the changed payroll fact through the worker refund, accounting adjustment, and remaining tax work. Every receipt is simulated.

Discovered

See the difference and the open questions.

A corrected year-to-date wage record changes the tax calculation. Inspect the derived difference and the human answers still required.

Answers recorded

Follow the refund and accounting adjustment.

The scenario supplies recorded answers. The engine projects the refund instruction, adjusting journal, and amended return. A releasable refund is not a settled refund.

Refund settled in simulation

Keep the remaining tax work visible.

Simulated receipts reconcile the refund. The amended return is projected, not filed. Close stays blocked until a disposition of the filed difference is recorded.

Open Close rehearsal and use Rehearsal scenario to choose the three “Late opening-wage correction” stages: “discovered, answers open,” “answers recorded, refund releasable,” and “refund settled on the simulated rail.” Selecting a scenario changes only the fictional example.

Correction cases buyers recognize.

Public rehearsals, engine capabilities, and planned service paths have different boundaries.

Public simulation

Late raise

A retroactive rate change reprices wages and taxes without overwriting the approved check.

Engine pattern

Missed timecard

Additional hours arrive after payday; the next run carries the corrected gross, taxes, and net.

Product path

Garnishment update

A legal order changes withholding and needs evidence for both worker support and compliance review.

Product path

W-4 change

The effective date, old election, new election, and affected checks stay visible.

Engine-supported

YTD transfer

Prior-provider totals become founding facts, and later corrections show exactly what changed. The public Close rehearsal follows a late opening-wage correction from discovery to a simulated refund.

Product path

Agency notice

Runbook assembles the payroll, liability, payment, rule, and correction evidence into a response packet.

What proof adds to payroll.

The buyer does not need cryptographic theater. They need an answer that survives review.
