If you do your accounting through QuickFile then QuickFile can populate the VAT return for you - the account will remain free if you create less than 1,000 ledger entries within a 12 month period.
I recommend taking a look at the following guides and checking out the ledger count, so you can see how this is broken down for your account:
- Account size explained
- How to determine what items make up your ledger count
- How do I check the size of my account?
I hope that helps.
