What is moms-redovisning?

A Swedish-language skill for preparing a small business’s VAT return from Bokio accounting data. VAT is the tax added to many sales and purchases, and Bokio is an accounting service.

Collecting transactions, checking VAT codes against the BAS chart of accounts, reconciling bank statements, and preparing information for the Swedish Tax Agency’s online service.

It helps find missing or incorrect VAT classifications and differences between accounting records and bank statements before filing with the Swedish Tax Agency.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00254	$0.01986
Opus 5	$0.00127	$0.00993
Sonnet 5	$0.00051	$0.00397
Haiku 4.5	$0.00025	$0.00199

Security

Grade A, and why

moms-redovisning 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 12d 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.

Moms-redovisning för svenska småföretag

Det här är en av de mest värdefulla återkommande uppgifterna för en svensk småföretagare. Felmoms är dyrt: rättning kostar tid, försenad inbetalning kostar ränta, och fel som upptäcks vid revision kan bli rejäla efterhandsbeskattningar.

När skillen ska köras

Användaren ber om momsförberedelse för en specifik period
Användaren frågar "vad blir momsen" eller "hur mycket ska jag betala"
Det är inom 14 dagar innan momsdeklarationens deadline
Användaren laddar upp ett Bokio-export och vill ha hjälp att förstå

Förutsättningar

Bokio MCP måste vara installerad och autentiserad. Verifiera detta först.
Om Bokio MCP saknas, säg det tydligt och hänvisa till INSTALLATION.md.

Workflow

Steg 1: Bekräfta period och bolag

Fråga om något är oklart:

Vilket bolag (om användaren har flera i Bokio)?
Vilken momsperiod (månad, kvartal, år)?
Vilken specifik period (t.ex. Q1 2026, januari 2026, helår 2025)?

Är användaren osäker, kolla Bokios companySettings eller motsvarande för att se vilken momsperiod bolaget är registrerat för.

Steg 2: Hämta data från Bokio

Använd Bokio MCP för att hämta:

Alla bokföringsverifikat i perioden
Konton enligt BAS-kontoplan, särskilt:
- 2610–2627 (utgående moms)
- 2640–2647 (ingående moms)
- 3001–3199 (försäljning Sverige)
- 3105, 3106 (EU-försäljning av varor)
- 3308 (försäljning till tredje land)
- 4056, 4515 (omvänd skattskyldighet)

Ta även med saldon från föregående periods avstämning för att se om något öppet finns kvar.

Steg 3: Sammanställ momsunderlag

Räkna ihop per ruta i Skatteverkets blankett (momsdeklaration):

Försäljning som beskattas:

Ruta 05: Momspliktig försäljning eller egna uttag exklusive moms
Ruta 06: Momspliktig försäljning där köparen är skattskyldig
Ruta 07: Inköp av varor från annat EU-land
Ruta 08: Inköp av tjänster från annat EU-land

Utgående moms:

Ruta 10: Utgående moms 25 %
Ruta 11: Utgående moms 12 %
Ruta 12: Utgående moms 6 %

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
