Frequently Asked Questions
Does AccountsOS explain the 3:12 rules?
Yes. Finn can walk you through the fåmansföretagsregler — calculating your gränsbelopp, whether to use the schablonmetoden or huvudregeln, and the mandatory salary threshold for qualifying dividends.
Does it support Swedish moms (VAT)?
Yes. AccountsOS tracks moms at 25%, 12% and 6% rates and handles the quarterly/annual filing thresholds. Finn knows which categories fall under each rate.
Is AccountsOS available in English for Swedish companies?
Fully. AccountsOS runs in English and Finn speaks plain English — including Swedish tax terminology where needed. Ideal for international founders running a Swedish AB.
How does AccountsOS compare to Fortnox on price?
Fortnox itself starts at around SEK 399/month, but you still need an accountant for anything complex. AccountsOS at £20/month replaces both the software and many of the questions you'd normally pay your accountant to answer.
