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.
