Area 1

Three-phase model and use cases.

Three phases per group and year, interlocked on one data set.

  • Phase 1 · ProvisionTop‑up tax provision for the consolidated financial statements, safe harbour approximation using prior-year CbCRs.
  • Phase 2 · Report & returnFull computation with actual figures, GloBE Information Return and return in a separate working copy.
  • Phase 3 · SubmissionValidation against the authorities’ error catalogues, GIR XML with country profile, reports for internal and external audiences.
  • Three scopes per yearFull compliance, Provision only or Report only – the interface shows only the steps needed.
  • Two calculation strategiesCompute all jurisdictions in full (assurance approach) or safe-harbour-first: only failing jurisdictions go into full computation.
  • Locking a yearThe provision computation stays as evidence; the reporting phase works on a working copy.

Area 2

Data entry and group structure.

Entities, holdings and special cases as the foundation of every computation.

  • Constituent entitiesOwnership structure, partnerships, flow-through entities, tax groups, partially owned parent entities.
  • Interactive org chartDrawn automatically from the data, zoomable, with PDF export.
  • Guided data entry wizardAround 100 fields per entity, step by step, help at every field.
  • CbCR entry via three routesExcel template upload, manual entry or XML import – one source for safe harbour tests and GIR.
  • World map in the analysisLow-taxed jurisdictions, compliant jurisdictions and the ultimate parent entity at a glance.

Area 3

The calculation engine with calculation steps.

Full GloBE computation per jurisdiction and entity, rule references right at the result.

  • Full GloBE computationGloBE income, covered taxes, deferred taxes, effective tax rate, top‑up tax percentage, top‑up amount, transitional rates of the substance-based income exclusion, loss elections, QDMTT credit, allocation to parent entities including partial ownership.
  • German depthIn line with the Minimum Tax Act: flow-through structures, tax groups, reduction for a flow-through ultimate parent.
  • Traceable calculation stepsReferences to the OECD Model Rules and local laws (Germany, Sweden) at the result.
  • Multi-year capabilityPrior-year snapshots and year-based persistence for comparing provision and final computation.

Area 4

Safe harbour tests on two levels.

The transitional CbCR safe harbour, complete, per jurisdiction and per year.

  • Three testsDe minimis test, simplified ETR test with year-dependent thresholds, routine profits test.
  • Two test levelsFor closing, the approximation using prior-year CbCRs; for the GIR, the CbCR of the GIR year.
  • Delta viewFlags jurisdictions that switch and newly require full data entry.
  • Intelligent gatingProtected jurisdictions need no full data entry – the effort stays with the jurisdictions that need it.
  • “Once out, always out”Excluded jurisdictions are respected consistently, all the way into the GIR XML.

Area 5

Plausibility checks before computation and filing.

Field, cross-field and group-level checks across all entered data.

  • Severity levelsMandatory correction or note, clearly separated.
  • Click jumps to the fieldEvery finding leads directly to the place where it is fixed.
  • Badge with open itemsThe state of quality assurance is visible at all times.

Area 6

GloBE Information Return create, validate, reuse.

The GIR XML is produced from the same data set as computation and safe harbour tests.

  • GIR XML following the OECD schemaCountry profiles: Germany (Federal Central Tax Office envelope), Sweden (header constraints), Austria (Ministry of Finance wrapper).
  • Built-in validationRule checks according to the authorities’ error code catalogues before filing, as a clear error list.
  • GIR importLoad a prior-year GIR and pre-populate group structure and data – also for corrective filings.
  • Evidence snapshotSafe harbour disclosures, exception sections and the evidence per jurisdiction from the same data set as the XML.

Area 7

Analyses and exports.

Results readable for closing, board and review.

  • Analysis dashboardJurisdiction and entity results, ETR overviews, top‑up amounts, safe harbour finding in plain language per jurisdiction.
  • Excel exportsProvision analysis with computation trail per jurisdiction, CbCR and safe harbour export, constituent entity overviews.
  • Entry templatesGerman, English and Swedish, complete in every language.

Area 8

LuCy, the AI assistant.

Expert knowledge the moment you need it – software help for subject-matter and usage questions, not tax advice.

  • Context-sensitive field helpAt every input field: LuCy knows the field, its meaning and the data context.
  • Chat panelFor open questions on the rules and on using the platform, with starter suggestions.
  • Curated knowledge baseAnswers from professionally maintained Pillar 2 knowledge, not from the open internet.
  • Proactive explanationsOn analysis results, for example why a jurisdiction stands out.
  • Dedicated moduleLuCy is a dedicated, optional module of the platform.

Area 9

Three languages and traceable.

For groups that work in several countries and have to explain results years later.

  • German, English, SwedishInterface, exports, templates and rule references – every text in all three languages, technically enforced.
  • Traceability as a principleLocked years, live-documented computation, documented divergences, evidence snapshots when the GIR is created.
  • No ERP projectStart with the data your tax department already has.

Area 10

Data paths: in and out.

No ERP integration required – in with existing data, out in the formats the close, the authority and the business need.

  • Country-by-country reports inCbCR via Excel template, XML import or manual entry – per year, one source for tests and GIR.
  • Entity data inGuided wizard per constituent entity, multilingual entry templates, help at every field.
  • Prior-year GIR inRead in an existing GIR, group structure and data pre-filled – also for corrective filings.
  • GIR XML outOECD schema with country profiles for Germany, Sweden and Austria, validated against the authorities’ error catalogues.
  • Excel outProvision analysis with computation evidence per jurisdiction, CbCR and safe harbour export, entity overviews.
  • Org chart outThe group structure as a PDF, generated automatically from the recorded shareholdings.
