Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

arvonlisaverotus scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Arvonlisäverotus — verollisuus, vähennykset ja kansainvälinen kauppa

Tämä skill jäsentää arvonlisäverokysymykset arvonlisäverolain (1501/1993) mukaan. Menettely (ilmoittaminen, korjaaminen, muutoksenhaku) kulkee oma-aloitteisten verojen verotusmenettelylain (768/2016) mukaan. Perusteet: ../verotusmenettely-ja-muutoksenhaku/references/verotus-perusteet.md.

Vastuuvapaus: analyysit ovat tarkistettavia — ei veroneuvontaa. Verokannat ja rajat haetaan aina lähteestä — ne ovat muuttuneet viime vuosina useasti. Katso verotus/CLAUDE.md.

Tarkista laki ja verokannat lähteestä

Hae AVL:n säännökset juristi:oikeustutkimus-skillillä ja voimassa olevat verokannat, alarajat ja vähäisen toiminnan rajat vero.fi:stä — älä koskaan muistista. EU-tasolla arvonlisäverodirektiivi ja EU-tuomioistuimen käytäntö ohjaavat tulkintaa — nosta EU-kytkös esiin rajat ylittävissä ja tulkinnanvaraisissa tilanteissa.

Perusjäsennys — käy aina nämä läpi

  1. Kuka myy? Verovelvollisuus: liiketoiminnan muodossa tapahtuva myynti; vähäisen toiminnan raja (euromäärä lähteestä); rekisteröitymisvelvollisuus ja vapaaehtoinen hakeutuminen.
  2. Mitä myydään? Tavara vai palvelu — ratkaisee myyntimaan ja verokannan; verosta vapautetut alat (mm. terveydenhuolto, rahoitus, kiinteistöt — rajaukset lähteestä).
  3. Missä myydään? Myyntimaasäännökset: kotimaa, EU (yhteisömyynti/ -hankinta, palvelujen pääsäännöt B2B/B2C, etämyynti ja OSS), EU:n ulkopuoli (vienti/tuonti).
  4. Kuka maksaa veron? Pääsääntö myyjä; käännetty verovelvollisuus mm. rakentamispalveluissa ja EU-hankinnoissa — soveltamisedellytykset lähteestä.
  5. Mikä verokanta? Yleinen ja alennetut — voimassa olevat prosentit ja niiden soveltamisalat aina lähteestä [tarkista verovuoden arvo — vero.fi].

Vähennysoikeus

  • Pääsääntö: vähennys verollista liiketoimintaa varten tehdyistä hankinnoista; vähennysrajoitukset (mm. edustus, yksityiskäyttö) lähteestä.
  • Jakaminen: osittain verollisessa ja verottomassa käytössä olevat hankinnat — jakoperuste dokumentoitava.
  • Laskumerkinnät ovat vähennyksen muotoedellytys — tarkista vaatimukset lähteestä; puutteellinen lasku vaarantaa vähennyksen.
  • Kiinteistöinvestointien tarkistusmenettely — vähennysten tarkistus käyttötarkoituksen muuttuessa; tarkistuskausi ja mekaniikka lähteestä.
