Maps a confirmed Dutch tax workpack to the matching Mijn Belastingdienst or Mijn Belastingdienst Zakelijk fields, with each value's source and every missing or blocked field: annual 2025 and 2026, voorlopige aanslag 2026, btw-aangifte, suppletie, opgaaf ICP, OSS/IOSS, and M- or C-biljet. Use when a workpack has been generated in this conversation or attached, and the user or the owning workflow asks for its field map. For a general question about which field or rubriek an item belongs in, use…

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 Field Mapper

Turn a reviewed workpack from a supported owner (annual 2025, provisional 2026,
VAT return or VAT correction, ICP, OSS/IOSS, international M-biljet or
C-biljet, or annual 2026) into a source-traceable field map for manual entry in
Mijn Belastingdienst. This skill is the only author of the field map. Continue the same tax conversation and
never announce that a mapper is taking over.

VAT return/correction workpacks for 2025/2026 are also mapped here, using
`reference/vat-field-map.md`. Their destination is the human's Mijn
Belastingdienst Zakelijk. A VAT map remains draft while VAT source-content
review is outstanding; it is preparation material, with no filing checklist.

ICP, OSS, migration/nonresident and annual 2026 workpacks are mapped as draft
preparation using `reference/cross-border-field-map.md`,
`reference/international-field-map.md` or `reference/annual-2026-field-map.md`.
Use the exact identity, path and owner in
`../nl-tax-shared-resources/reference/workflow-scopes.yaml`. Their pending
source-content review and their pending form, scheme or annual schema review
block `review_ready` and an entry checklist. Annual 2026 and M/C rows are
…

How to install

The exact contents, by fingerprint
mdr add cyanxxy/nl-tax-agent-skills/nl-tax-field-mapper@sha256:1b1fc8e4cd7d1121

The 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.
