Official schema first
The OECD source remains the authority for the GIR XML schema and user guide. For 2026 planning, GIR.WTF does not duplicate the official documentation; it implements the technical workflow around it.
GIR XML schema
GIR XML Schema
For OECD GIR XML schema 2026 planning, teams should start from the official source and then map business answers into a technical workflow. GIR.WTF implements that layer through guided mapping, validation and export support.
GIR.WTF handles the technical layer. The user and their advisers remain responsible for the underlying tax and legal positions, the reporting information and the final filing decisions.
What GIR.WTF does
Technical execution layer, not a tax opinion.
GIR.WTF combines guided GIR XML generation, browser-based technical validation, schema mapping, Belgian technical checks and XML export in one focused product workflow.
From schema to software workflow
The schema becomes usable when business inputs can be mapped to required XML elements and checked before export. GIR.WTF turns that mapping into a guided workflow.
XSD validation support
Schema readiness includes technical checks for structure, formats and required elements. It remains separate from determining tax treatment or legal positions.
Official sources
Built around authoritative technical materials.
GIR.WTF is implementation software. OECD and FPS Finance remain the authoritative sources for the GIR XML schema, Belgian materials and official filing context.

Practical questions
Choose the path that matches the work in front of you.
Each focused GIR XML page starts from a concrete implementation problem: generating XML, validating structure, mapping the OECD schema, preparing Belgian context or reviewing validation-error behaviour.
Find the official GIR XML schema source
The OECD schema and user guide remain the authority. GIR.WTF keeps that source linked and positions the product as the implementation layer.
Map business answers into schema-ready XML
The practical work is turning reporting-period, entity, jurisdiction and return data into a structure that matches the expected XML shape.
Connect schema readiness to validation
Schema readiness should lead into technical validation, visible data gaps and export preparation rather than a one-off document download.

Reviewed against technical source material.
The public pages show the same boundary as the product: official sources define the schema and Belgian filing context; GIR.WTF provides the technical workflow around structured input, validation messages and export preparation.
Focused GIR XML pages answer concrete implementation questions.
The hub, generator, validator, schema, Belgium and validation-error pages each connect practical implementation questions with source-linked context and clear next workflow steps.
OECD GIR XML schema 2026 planning stays source-led.
Teams preparing 2026 GIR XML work should verify the current OECD schema and user-guide source first. GIR.WTF adds a guided implementation layer around mapping, validation and export.
Belgian GIR XML materials are treated as technical inputs.
FPS Finance forms, tools, XSD and validation-rule materials are linked as official sources. GIR.WTF keeps Belgian implementation checks separate from tax advice or filing guarantees.
Public validation messages point to reviewable issues.
The browser demo exposes missing technical fields, malformed XML, unsupported document shape and format issues without sending pasted XML to the server.
High-intent GIR/GIRNOT workflows link back to the hub.
Generator, validator, schema, Belgian validation rules, GIRNOT Belgium and MyMinfin notification preparation all resolve into the central GIR XML workflow.
GIR XML workflow
One product, focused technical pages.

FAQ
Direct answers for GIR XML implementation.
Where is the official GIR XML schema?
The official GIR XML schema and user guide are published by the OECD. GIR.WTF links to the OECD source and builds implementation software around it.
Does GIR.WTF replace the OECD schema documentation?
No. GIR.WTF is implementation software. The official OECD documentation remains the source for the schema itself.
Is this the OECD GIR XML schema for 2026 planning?
This page supports OECD GIR XML schema 2026 planning by pointing to the official source and explaining the technical implementation workflow around it. It is not a replacement for official OECD documentation.
Portal access
Prepare GIR XML without manual XML editing.
Request access to the GIR portal. The first step is technical GIR/GIRNOT scope, data-gap and XML-readiness intake without submitting confidential production data through the public form.
