Frequently Asked Questions
Why do I need Ltd company specific accounting software?
Limited companies have unique requirements: Corporation Tax instead of Income Tax, Companies House filings, dividend vs salary decisions, director's loan rules, and different expense categories. Generic software often gets these wrong or makes them harder than necessary.
How does the Companies House sync work?
AccountsOS connects to Companies House API to pull your company details and filing deadlines automatically. Confirmation Statement due? Annual Accounts deadline? Corporation Tax filing date? All tracked and synced, with reminders before they're due.
Can it calculate my Corporation Tax correctly?
Yes, including the marginal relief calculations that trip up many founders. For profits between £50k and £250k, the CT rate isn't simply 25% - there's a complex relief calculation. AccountsOS handles this automatically.
What about director's loan accounts?
AccountsOS tracks all movements on your director's loan account and warns you about S455 tax implications if your loan balance exceeds limits. No more end-of-year surprises about owing tax on money you borrowed from your own company.
