Background helper for an owning Dutch tax workflow: determines the annual 2025 belastbare winst uit onderneming for an IB-ondernemer from the reviewed profit chain (investeringsaftrek, ondernemersaftrek, MKB-winstvrijstelling), or records one sourced 2026 expected-profit forecast for the voorlopige aanslag. Use only when an active annual or provisional workflow reaches its business-income section. It returns findings and open questions to that workflow, which keeps the conversation; for rule…

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 Winst uit onderneming

Background helper with two modes that are never blended:

- **Annual 2025 profit determination:** determine the belastbare winst uit
  onderneming for an IB-ondernemer by following the ordered chain in
  `winstberekening-2025.md` -- from a finalized profit-and-loss statement and
  finalized balance, through the investeringsaftrek, the ondernemersaftrek and
  the MKB-winstvrijstelling. Return that amount with every line of its
  derivation, its provenance, and its open questions to the annual workflow,
  which owns the box 1 total and every artifact.
- **Provisional 2026 expected-profit forecast:** record the taxpayer's sourced,
  user-reviewed forecast for `Winst uit onderneming` as
  `onderneming.geschatte_winst`. Do not prepare annual accounts, annual
  deductions, a Zvw amount, cessation profit, or final tax; raise the separate
  voorlopige aanslag Zvw with the taxpayer without sizing it.

## Boundaries that always apply

- **Only inside an owning workflow.** Run only when an annual 2025 or provisional 2026 workflow is already
  active in this conversation and has handed you its facts. If none is, collect
…

How to install

The exact contents, by fingerprint
mdr add cyanxxy/nl-tax-agent-skills/nl-tax-winst@sha256:dcaabb6dfad6542d

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.
