Frequently Asked Questions

Do I really need a specialist contractor accountant?

For most contractors, no. The 'specialist' bit is mainly about understanding IR35, dividend/salary mix, and allowable expenses. AccountsOS has all this knowledge built in, with Finn, your AI accountant, who understands contractor-specific rules.

How does cheap contractor accounting handle IR35?

AccountsOS applies the correct expense rules based on your IR35 status. Inside IR35? We treat you like an employee for expense purposes. Outside IR35? Full contractor expenses apply. You tell Finn your status, it handles the rules.

Can AccountsOS optimise my salary/dividend mix?

Yes. Finn considers your expected profit, NI thresholds, dividend allowances, and tax bands to suggest optimal extraction. It recalculates as your situation changes throughout the year.

What does it cost?

£20/month, all-in. 14-day free trial, no card needed upfront. That includes Finn, VAT/MTD, receipt scanning, bank feeds, invoicing, and everything else. No add-ons, no surprises.
