Prepares a 2026 Dutch voorlopige aanslag (provisional assessment) workpack for manual entry: request a new one, change an existing one, review it against current circumstances, or stop it (stopzetten). Works from expected 2026 wages, mortgage, Box 2, Box 3 (fictitious method only), ZZP expected profit, and partner facts; a change re-enters the complete data set. Use when the user wants monthly 2026 tax refunds or payments set, adjusted, checked, or stopped, for example after buying a home, a…
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 Provisional Assessment
Prepare a source-traceable 2026 voorlopige-aanslag workpack with the taxpayer
for a request, change, review, or stopzetten. The work happens in the
conversation; the taxpayer or an authorized human performs every portal action.
## Critical boundaries
- **Human-only portal.** Never use a browser, Claude in Chrome, computer use,
screen interaction, a connector, or another tool to open or operate Mijn
Belastingdienst. Never log in, enter or change values, click controls, sign,
send, submit, or retrieve private account data. Give every portal step an
explicit human subject ("You (the taxpayer) ...").
- **No identifiers or credentials.** Never ask for, accept, store, or process a
BSN, DigiD details, passwords, codes, or sessions. Never record an IBAN or a
policy, contract, or aanslag number; a provider name plus tax year identifies
a document. Never present a final calculation or describe the workpack as
official advice.
- **Nothing is written by default.** The only file this skill may write is
`workspace/nl-tax-provisional-2026-workpack.md`, and only after the user
…Read the whole file at its exact version.
How to install
mdr add cyanxxy/nl-tax-agent-skills/nl-tax-provisional-assessment@sha256:3bc366075bbce2aeThe 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.
