I am a UK sole trader who has been VAT registered for a few years.
Decided to de register for VAT due to being under £80,000 turnover.
Submitted my final VAT return, but made a mistake of copying wrong value into form. I paid £1,500 with only £300 sales for that period.
I understand it is normal to claim it back on the next return.
Would I need to re register for VAT or is there another way?
