Frequently Asked Questions
How does IR35 status affect my bookkeeping?
Significantly. Inside IR35 contracts mean you're treated like an employee for tax purposes - fewer claimable expenses. Outside IR35 gives you full contractor expense rules. AccountsOS tracks your status and applies the correct treatment automatically.
Can I have some contracts inside and some outside IR35?
Yes. AccountsOS tracks IR35 status per contract/client. Expenses are allocated correctly based on which engagement they relate to. The software handles the complexity so you don't have to.
What's the 24-month rule and how does AccountsOS handle it?
If you work at the same client site for more than 24 months, travel expenses to that site are no longer claimable. AccountsOS monitors your client relationships and warns you when you're approaching this limit.
How does salary/dividend optimisation work for contractors?
The AI analyses your expected profit, considers NI thresholds, dividend allowance, and your personal tax situation to suggest the most tax-efficient way to extract money from your Ltd company. It updates as your circumstances change.
