There are a few common issues when it comes to submitting your VAT return.

I have provided a list below with a few frequently occurring examples:

- Check the VAT registration number on the template

- Check the dates on the template

- Sometimes it's due to connection issues with HMRC, therefore logging in and then clicking the 'REFRESH' button on the Obligations/VAT details page may rectify any issue(s)

Please find attached an Excel VAT template which may be of use to you.
