# FAQs: VAT & Tax Treatment

## Questions about VAT calculations and tax compliance

**How accurate are your VAT calculations?**We calculate VAT using invoices, sales data, and bank feeds. Our team manually reviews edge cases like reverse charges. You’ll receive full workings with audit trails.

**What if I find errors in the VAT workings?**We share draft VAT returns before submission. If anything looks off, flag it. We’ll review and issue a corrected version.

**Do you support cash basis VAT?**Yes. We can set this per client during onboarding.

**What about RTD (annual return)?**We provide breakdowns by VAT rate where supported. Some POS systems don’t capture this – you’ll need to extract from those systems directly.

**How are ROS payments handled if you don’t have ROS access?**We infer the taxhead based on context. If we’ve prepared the VAT return, we know if the payment relates to VAT. Similarly, payroll journal context helps identify PAYE. If we can’t identify the payment, we raise a Rex request for clarification. Ad hoc payments are queried, recurring ones are usually identified automatically.
