* fix(arsredovisning): truthful K3 policy note and GRANSKNINGSUTKAST watermark The K3 redovisningsprinciper note asserted policies the engine does not follow: full balansrakningsmetoden deferred tax and finance lease capitalization. The note now states actual practice: deferred tax only on obeskattade reserver at 20,6 percent, all leases expensed as operational. Every K3 report is classified AR-K3-DRAFT-ONLY, so the K3 PDF now carries a fixed rotated GRANSKNINGSUTKAST watermark on every page, and the arsredovisning studio shows an always visible AttnLine for K3 explaining that the document cannot be locked or filed via Accounted yet. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(arsredovisning): stop the two K3 deferred-tax notes contradicting each other The redovisningsprinciper note said deferred tax on obeskattade reserver is not separately recognised in juridisk person, while the "Uppskjutna skatter" note right after it disclosed exactly that split plus the 8940 movement. A signed arsredovisning cannot say both. Both notes are now driven by one derivation (deriveLatentTaxMovement in build-data.ts, computed before note 1 is built): with no 2240/8940 activity the policy paragraph states the gross treatment K3 29.37 permits and no movement note is emitted; with a 2240 balance the paragraph discloses the recognised liability and points at the movement note. Neither text claims a measurement rate or an origin the builder cannot verify, since a balance can come from the K3 bokslutsdisposition, a legacy posting or an SIE import booked at 22 or 21,4 percent. The leasing paragraph now states the basis for its blanket treatment: the document is always a single juridisk person with no koncernredovisning, so the K3 punkt 20.29 exemption applies. Without that qualifier the paragraph asserted a treatment that is not the general K3 rule. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(arsredovisning): never assert a K3 policy the books can contradict Three cases where the principles note still made claims it could not back: a read failure on the 2240/8940 figures printed the affirmative denial anyway, the leasing paragraph asserted a fact about the entity's group obligations that a Koncernforhallanden note in the same document can contradict, and the blanket operational-lease claim survived even when the balance sheet carries leased assets on 1260/1269. Deferred tax becomes a tri-state (none/recognized/unknown) and leasing is driven by the same trial balance.

Accounted
Open-source Swedish accounting software for sole traders (enskild firma) and limited companies (aktiebolag). Double-entry bookkeeping that complies with Swedish accounting law, built to be operated by you or by your AI agent.
Website · Hosted app · Documentation
Why Accounted?
Compliant by construction. Accounted implements double-entry bookkeeping under Swedish accounting law (Bokföringslagen). Voucher immutability, sequential voucher numbering, period locks, and 7-year document retention are enforced by database triggers, not by convention. Corrections are made the legal way, with reversal entries (storno), never by editing history. See ARCHITECTURE.md for how.
Agent-native. The full bookkeeping engine is exposed as 100+ MCP (Model Context Protocol) tools with scoped API keys, so an AI agent can do the books in Accounted: categorize transactions, draft vouchers, reconcile periods, and prepare declarations. Posting is staged for human approval, so the agent proposes and you decide.
Yours to run. AGPL-3.0 licensed and fully self-hostable with Docker and Supabase. Use the hosted version at app.gnubok.se or run your own.
