Why Correcting VAT Return Errors UK Matters

Three Ways to Correct VAT Return Errors
You now have three methods for correcting VAT return errors UK:
- Update the next VAT return
- Correct the error online
- Notify HMRC in writing
Each method suits different error types and values. Let’s explore these options in more detail.
Update the Next VAT Return
If your error is under £10,000, or between £10,000 and £50,000 and under 1% of box 6 net outputs, and it was made carelessly—not deliberately—you can correct it in your next return.
- You adjust the figures in the next VAT return.
- VAT error value depends on the net difference in amounts owed or refunded.
- This method keeps things simple. Your next VAT return acts as the correction form.
Correct the Error Online
For errors over £50,000, or between £10,000 and £50,000 and exceeding 1% of box 6, or if the mistake was deliberate, you must notify HMRC online.
Steps to Report Online if DIY
