skat-dk

name: skat-dk description: skat.dk — the Danish Tax Agency's public citizen portal. Covers the nine top-level borger sections, URL & language conventions, TastSelv login launchers, on-site Cludo search, and internal APIs (Next.js JSON data feed, Cludo search API, sitemap). Use when looking up Danish tax topics, finding self-service launchers, navigating skat.dk's URL space, fetching content programmatically, or translating articles across languages. last-updated: 2026-05-31

skat.dk — Danish tax agency citizen portal

https://skat.dk/ is the Danish Tax Agency's public website. The /borger subtree is the citizen-facing information layer (vs. /erhverv for businesses); both are anonymous and built on a Next.js front-end backed by an internal Umbraco Headless CMS. Personal data and self-service forms live on https://www.tastselv.skat.dk/ (TastSelv) and require MitID or a legacy TastSelv-kode. There is no public read API for personal tax data.

Default page language is Danish; respond in Danish unless the user signals otherwise. Each Danish article has matching slugs in up to seven languages.

The skat CLI — use this first

For everything programmatic — searching, reading page content/metadata, walking the navigation tree, finding language siblings, enumerating URLs — use the skat CLI. It wraps the three useful read surfaces (Next.js data feed, Cludo search, sitemap) so you should not fetch pages or call those APIs by hand. The CLI can be run from anywhere, no need to point at the skill directory:

skat <subcommand> [options]

Prerequisites

Verify the CLI is installed:

which skat

If missing, install it editable with pipx (from the skill directory). First make sure pipx itself is available, then install:

# Ensure pipx is installed
which pipx || python3 -m pip install --user pipx
python3 -m pipx ensurepath

# Install the skat CLI
pipx install -e <path-to-skat-dk-skill>

After installing, confirm skat is on the PATH (you may need to restart the shell so pipx ensurepath takes effect):

which skat

Pure Python standard library — no extra dependencies. Each subcommand exits non-zero on HTTP error.

Command reference

# Current Next.js buildId (rotates on every deploy; the other commands auto-detect it)
skat buildid

# Fetch a page's full JSON model from /_next/data/ (Danish default).
# Use this instead of curling /_next/data/...json by hand.
skat page borger/fradrag                          # Danish article
skat page individuals --locale en-us              # English mirror (locale: da-dk|en-us|de-de|uk|pl|ro|lt|kl)
skat page borger --field 'pageProps.content.page.childPages[].url'   # dotted extract — walk the tree
skat page borger/fradrag --field 'pageProps.content.page.pageLanguageVersions[].pageUrl'  # language siblings
skat page borger/fradrag --build-id <id>          # pin an explicit buildId

# Cludo on-site search across a skat.dk-family site.
# Use this instead of POSTing to the Cludo API by hand; /soeg HTML is NOT server-queryable.
skat search fradrag                               # SKAT / da (default)
skat search "tax deduction" --lang en             # English engine (--lang da|en|de)
skat search vurdering --site VURDST               # sister-site theme (see `skat engines`)
skat search fradrag -v                            # also print result descriptions
skat search fradrag --size 50 --page 2            # paginate (pageSize / page number)
skat search fradrag --facets Category             # request facets
skat search fradrag --engine 13369                # explicit engineId, overrides --site/--lang
skat search fradrag --raw                         # raw Cludo JSON response

# Cludo public engine settings (quicklinks, assistant config; no auth)
skat settings 13369                               # SKAT/da engine

# Print the Cludo customerId / engineId map (which --site/--lang -> engine)
skat engines
skat engines --raw                                # raw JSON

# Enumerate URLs from /sitemap.xml (all languages, single file)
skat sitemap --prefix /borger/ --limit 50         # filter by path prefix, cap results

--raw is available on search and engines for the unformatted JSON response. For ad-hoc reading of body copy, skat page returns the page model.

Citizen section paths (values for skat page <path> and skat sitemap --prefix)

The nine top-level /borger sections. Use the path (without leading slash) as the skat page argument, or with a leading slash as skat sitemap --prefix:

Search site / engine values (for skat search --site/--engine, skat settings <engine>, skat engines)

skat search --site <SITE> selects a theme; --lang da|en|de picks the language variant. Run skat engines for the authoritative live map. The main themes and their engine IDs (used by --engine and skat settings <engine>):

Additional da-only --site values: SANST, SKM, SKTST, SKTFV, ADST, UFST, WEBGUIDE, ITTI, ZISE, LOTTERIREGLER.

Common citizen tasks

• Find an article on a tax topic → skat search <topic> (add --lang en/--site as needed), or skat page borger/<section> --field 'pageProps.content.page.childPages[].url' to browse a section's children.
• Read in English/German → skat search "..." --lang en, or pull language siblings: skat page borger/<section> --field 'pageProps.content.page.pageLanguageVersions[].pageUrl'.
• List all citizen URLs → skat sitemap --prefix /borger/.
• Vehicle / customs / property / debt topic → search the sister-site theme: --site MOTORST | TOLDST | VURDST | GAELDST (run skat engines for the full list).

Out of scope

Personal tax data and self-service forms require MitID/TastSelv login at the website and are not covered by this skill.
