Bokføringsloven, VAT, A-melding and SAF-T — all built in from day one. Not translated or bolted on.
Stripe revenue syncs automatically. Connect your bank in one click. Everything is API-addressable.

Monthly pay runs that just work. Kantax fetches tax cards from Skatteetaten, calculates OTP and arbeidsgiveravgift, and gives you A-melding numbers ready to paste into Altinn.

Yes. Kantax follows bokføringsloven and bokføringsforskriften. Receipts archive for 5 years, invoice numbering is gap-free, and all data is exportable as SAF-T on demand from the Tax Administration.
Yes, but it requires some manual work in the 2026 version. We're building an importer for receipts, customers, and suppliers. Contact us — we'll help you personally through the switch during the early phase.
