The threshold for VAT registration remains at £85,000 in 2019/20. If your annual turnover is above the threshold then you are required to file VAT returns.
If you are VAT registered then you must file your returns using the Making Tax Digital Service (MTD). You can sign up for this here: https://www.gov.uk/guidance/sign-up-for-making-tax-digital-for-vat
It is also important that you make sure that you file your VAT returns in time, we have a helpful timetable for when you need to file your VAT returns here.
If you are unsure of how to file your VAT return or would prefer to have someone else do it then make sure to get in contact! We will be happy to help!
