What This Agent Does
Payroll corrections are among the most error-prone processes in payroll accounting. Every correction must retroactively calculate the tax and social insurance implications - across multiple months. Incorrect corrections compound the error instead of fixing it.
The Decision Layer breaks every payroll correction into ten decision steps. The difference is identified automatically. The cause is classified by LLM (collective agreement change, back-payment, input error). The retroactive period follows statutory deadlines. Tax and social insurance implications are calculated rule-based. The employee receives a comprehensible explanation of the correction.
Approval of every correction is under the four-eyes principle by a human - the agent calculates and prepares but does not decide. The result: fewer follow-on errors, faster correction cycles and transparent communication to affected employees.

Prerequisites
- Payroll system with access to historical payslip data
- Payroll Tax Agent for tax recalculation
- Social Insurance Reporting Agent for corrected contribution statements
- Communication template for employee notifications
Governance Notes
Mixed decision distribution (1H / 7R / 2A). Human approval under the four-eyes principle is mandatory for every correction. GoBD-compliant: the original posting is not changed but reversed and re-posted. Every correction is fully documented with original document, correction reason and recalculation.
EStG and SGB as direct legal bases for retroactive corrections. Deadlines for payroll tax corrections (Paragraph 41c EStG) and social insurance corrections must be met. Paragraph 203 StGB relevant: correction data is particularly sensitive as it exposes errors.
§203 StGB-relevant data is encrypted end-to-end and never passed to AI models in plain text.
Process Documentation Contribution
Infrastructure Contribution
The correction pattern (reversal plus re-posting instead of overwriting) is the GoBD-compliant base pattern for all agents that need to modify postings. The retroactive recalculation across multiple periods is reused by the Credit Note Agent and other correction processes. The employee communication logic establishes the pattern for transparent explanation of agent decisions. Builds Decision Logging and Audit Trail used by the Decision Layer for traceability and challengeability of every decision.

Frequently Asked Questions
How far back can payroll corrections reach?
The agent calculates corrections within statutory deadlines. For payroll tax, Paragraph 41c EStG applies (current plus three preceding calendar years). For social insurance contributions, the reporting deadlines per SGB IV apply. The agent automatically checks whether a correction is still within deadline.
What happens when the correction leads to a repayment by the employee?
The agent calculates the net difference and creates a comprehensible explanation. The withholding only happens after approval under the four-eyes principle. The decision record is viewable by the employee - they can trace the calculation and challenge it.
Can the agent bundle multiple corrections for the same employee?
Yes. The agent recognises when multiple correction reasons exist for the same period and calculates a consolidated correction. This avoids multiple net withholdings.
