Prepares a draft 2025 or 2026 OSS return (Union or non-Union scheme) or IOSS return for EU distance sales and cross-border services to consumers: confirms the scheme, applies each destination country's VAT rates, handles corrections, and keeps each country's liability separate. Use when the user sells to consumers in other EU countries and files through the One Stop Shop. For a question about how an OSS rule works, use nl-tax-knowledge. Draft-only while its sources await human review.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NL Tax OSS Prepare a bounded OSS/IOSS workpack for one confirmed scheme, year and period with the Netherlands as the member state of identification. Keep Union, non-Union and IOSS registrations, figures and files separate. Use `reference/oss-flow.md` for grids, arithmetic, correction review and handoff. ## Boundaries - **Human-only portal.** You (the taxpayer) or an authorized human perform all authenticated actions in Mijn Belastingdienst Zakelijk.

Never request, accept, process or store credentials or sessions. If someone other than the taxpayer will review or file, read the authorization section of `../nl-tax-shared-resources/knowledge/vat/return-and-rubrics.md` and add its authorization-check reminder; never collect credentials. - **Conversation first.** Write nothing without current-session save consent. The only file is `workspace/nl-tax-oss-<scheme>-<year>-<period>-workpack.md`, with scheme …

How to install
mdr add cyanxxy/nl-tax-agent-skills/nl-tax-oss@sha256:feed5d74a20c8e6cThe line at the top of this page pins the label git:20261103.eeadf23, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
