Thanks for your question
You would only have been placed on the flat rate scheme had an application been made to HMRC
VAT for this specific scheme and your rate at flat rate is determined by your trade (so varies) and if you had been standard rate then you would be able to claim VAT suffered against the standrd rate charged, so I would need all this additional information to advsie further.
1) What rate have HMRC advised you to charge on the flat rate scheme
2) When you advise £61,000 is this excusing VAT (flat rate) or including
3) What VAT did you suffer for the same period on which this £61,000 applies (so VAT suffered on purchases)
I can then advise further
