What This Agent Does
A tax audit takes on average 6-8 weeks. The biggest time drain is not the audit itself but the preparation: compiling data, analysing the audit order, identifying risk areas, drafting answers to auditor questions. In many companies, a tax audit ties up one clerk for weeks.
The Decision Layer turns tax audit preparation into a structured process. The agent analyses the audit order and identifies the audit period and relevant tax types. Data is exported in IDEA format, Z1/Z2/Z3 access prepared. Risk areas are proactively identified - where might auditors probe deeper? Draft answers are prepared; the final argumentation strategy stays with the tax advisor.
The result: tax audit in 2 weeks instead of 8. All data available on day one. Risk areas identified and answers prepared. The tax advisor can focus on argumentation instead of data searches.

Decision Record and Right to Challenge
Every decision this agent makes or prepares is documented in a complete decision record. Affected parties (employees, suppliers, auditors) can review, understand, and challenge every individual decision.
Prerequisites
- Complete ERP data archive for the audit period
- IDEA/GDPdU export functionality
- Access to prior tax audit reports as pattern basis
- Current procedural documentation of all tax-relevant processes
Governance Notes
The tax audit is conducted per AO Paragraph 193 ff. The auditor has the right to Z1 access (direct data access), Z2 access (indirect access via evaluations) and Z3 access (data carrier provision in IDEA format). Missing or incomplete data can lead to estimation of the tax base.
The procedural documentation per GoBD is the most frequent point of objection. The Decision Layer generates this documentation automatically - it is not a retrospective document but technical proof of how every decision was made. Paragraph 203 StGB is particularly relevant for client support by tax advisors.
§203 StGB-relevant data is encrypted end-to-end and never passed to AI models in plain text.
Process Documentation Contribution
Infrastructure Contribution
The Tax Audit Preparation Agent uses the infrastructure of all other Finance agents: the GoBD-compliant archiving of the GoBD Compliance Agent, the posting data of the GL agents, the tax calculations of the VAT and Payroll Tax agents. It is the ultimate proof that the agent infrastructure works: when the tax audit runs smoothly, the Decision Layer has proven its value.
Builds Decision Logging and Audit Trail used by the Decision Layer for traceability and challengeability of every decision.

Frequently Asked Questions
Can the agent conduct or represent in the tax audit itself?
No. The agent prepares the audit and supports during the audit with data requests. The argumentation with the auditor, negotiation and legal remedy decisions remain with the tax advisor.
How does the agent identify risk areas?
The agent analyses frequent audit focus areas (entertainment receipts, transfer prices, VAT assignments), compares with industry-standard metrics and reviews prior audit reports for recurring objections.
What does a poorly prepared tax audit cost?
Beyond the direct staff time, missing data or incomplete procedural documentation often leads to estimations by the tax office - typically well above the actual values. Good preparation is an investment that pays for itself many times over.
