Collects evidence for a resident 2026 Dutch annual income-tax return (aangifte inkomstenbelasting 2026) into a draft-only workpack until the 2026 year-end figures and forms are final. Use when the user wants to start preparing that return by gathering or organizing actual 2026 income, mortgage, savings, or business documents. For a 2026 estimate or monthly refunds or payments, use nl-tax-provisional-assessment (voorlopige aanslag); for a rule question, use nl-tax-knowledge.

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

# Annual income tax 2026

After any context compaction or summary, read the files named below again,
plus any helper `SKILL.md` in use, before your next reply.

Prepare a resident annual 2026 return with sourced actual facts and open items.
Read `../nl-tax-shared-resources/runtime-contract.md`
and `../nl-tax-shared-resources/runtime-workpack-files.md`, then
`reference/annual-2026-flow.md`. This owner has a separate year and file from
annual 2025 and provisional 2026. Never substitute their rates or field maps.

## Boundaries

- **Human-only portal.** You (the taxpayer) or an authorized human perform all
  authenticated portal actions. Never use a browser, Claude in Chrome,
  computer use, screen interaction, a connector or any tool to open or operate
  Mijn Belastingdienst; never log in, enter values, sign, send, submit, or
  retrieve private account data. Never handle credentials or sessions.
- **Conversation first.** Write nothing unless session save consent is active.
  Write only `workspace/nl-tax-annual-2026-workpack.md`. Never copy, move,
  rename, rewrite or convert evidence. Use aliases, no full identifiers.

How to install

The exact contents, by fingerprint
mdr add cyanxxy/nl-tax-agent-skills/nl-tax-annual-return-2026@sha256:61f3de622a67664c

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.
