Swedish Year-End Closing (Bokslut)

This skill provides everything needed to perform or implement a complete Swedish year-end closing for Aktiebolag (AB) and Enskild firma.

Quick decision tree

1. AB → always årsredovisning → K2 (if mindre and eligible) or K3
2. Enskild firma, revenue ≤ 3 MSEK → K1 förenklat årsbokslut (BFNAR 2006:1) — see references/k1-forenklat-arsbokslut.md. Critical: P-fond and expansionsfond must NEVER be booked in räkenskaperna for EF (only as upplysning U1/U2); the opposite of AB. NE-bilaga handles the avdrag.
3. Enskild firma, revenue > 3 MSEK → full årsbokslut (BFNAR 2017:3)

How to use this skill

When a user asks a bokslut question:

1. Identify whether it's about AB or Enskild firma (or both)
2. Identify which phase/topic the question relates to
3. Read the relevant reference file(s)
4. Answer with specific BAS account numbers and journal entries where applicable
5. Flag K2 vs K3 differences when relevant
6. Include current rates/thresholds from the rates table

Always distinguish between items that are booked in the accounting vs items that exist only in the tax declaration:

• Booked: överavskrivningar, periodiseringsfond (AB only), skatt på årets resultat (AB only)
• Declaration only: periodiseringsfond (EF), expansionsfond, räntefördelning, schablonintäkt on periodiseringsfond, egenavgifter schablonavdrag
