§01 — Role and Tax Environment
Heads of tax govern. Corporate tax prepares. Indirect and employment tax specialists carry jurisdiction-specific obligations. Transfer pricing documents. Each has a different boundary.
Governs scope, policy, risk appetite, review expectations and release accountability across the function.
Prepares provisions, positions and returns with source-linked support and visible calculation traces.
Handles jurisdiction-specific rules, registration thresholds, rates and filing obligations.
Structures documentation, comparables reasoning, method selection and defence files.

§02 — Tax Professional Capability System
Every capability operates within a stated boundary. None issues a tax opinion, concludes a position, files a return or substitutes for professional judgment.
01Ask Accounting Questions
Jurisdiction-aware research over admitted tax authority, bound to taxpayer, period and tax type.
Does not issue a tax opinion or conclude a position.
02Workflow Mode
Structures research, analysis, calculation, documentation and review through governed stages.
Does not auto-advance a stage or file a return.
03Review Mode
Surfaces significant judgments, unresolved conflicts and changes for reviewer attention.
Does not sign off or clear a review note.
04Learning & Practice Mode
Builds understanding through synthetic scenarios with source-linked feedback.
Does not certify competence or authorize professional work.
05Admin Mode
Governs roles, source admission, retention, integrations and provider controls.
Does not grant itself authority or bypass separation of duties.
06Human Escalation
Routes unresolved conflicts, thresholds and consultation triggers to a named person.
Does not resolve the matter or substitute for consultation.
07Source-Governed Intelligence
Restricts reasoning to admitted authority with status, effect and applicability attached.
Does not reason from unadmitted or unverified sources.
08Accounting Ontology
Governs concepts, relationships and jurisdiction mappings as typed, versioned objects.
Does not infer a mapping that has not been approved.
09RAG Source Bundles
Assembles the eligible, versioned authority set a question may draw on.
Does not widen the bundle implicitly at query time.
10Audit Evidence Ledger
Preserves sources, context, retrieval, output, review and action for each interaction.
Does not assert that a position is correct or sustainable.
11Evaluation & Benchmarks
Gates release on defined quality, coverage and regression thresholds.
Does not promote a capability that fails its gate.
12Enterprise Integrations
Connects approved tax, ERP, document and identity systems within an authorized scope.
Does not treat connectivity as authority to write or file.
§03 — Tax Context Model
Jurisdiction, tax type, taxpayer, period, authority level, filing status, materiality, confidentiality, intended use and permission — each requested, each recorded.
Country, state, province or locality. Never inferred from browser locale or user address.

§04 — Authority, Status and Reliance
A cited source is not automatically controlling. Source type, issuing body, authority level, status, effective history, applicability and conflicts are all visible without a lookup — because each changes how far a source can be relied upon.

§05 — Research, Workflow and Calculation Workbench
From issue framing through retention — each stage has a control, a review requirement and an evidence record. No stage produces a tax opinion or files automatically.
Stage 01
The question, taxpayer, period and intended use are stated before research opens.

Tax research memorandum · synthetic taxpayer · preview
Conclusion withheld. A tax position requires a qualified human determination before it may be relied upon.
§06 — Privacy, Security, Client and Evidence Rules
Tax data is among the most sensitive personal and business information an organization holds. Tenant isolation, classification, retention and residency are not settings — they are requirements, applied at every layer.

Integration action modes
§07 — Tax Workflow Stage Gates
This gate model separates readiness, validation, evaluation, preparation, control testing, human approval and authorized execution — with a named decision at each gate.
01Readiness
Taxpayer, jurisdiction, period, intended use and permission confirmed.

Exit gate — authorized release, verified after.
08Ongoing Assurance
Retention, revalidation and source-change monitoring after close.
Exit gate — revalidation interval set.
