VAT return date error

The following error message "The VAT return period dates on this return don't match what HMRC have on record." means HMRC expected a VAT return with different dates than those on the return you’re trying to submit.

To resolve this issue, follow these steps:

No data found error

The following error message "The remote endpoint has indicated that no data can be found" means HMRC doesn’t hold any data for your company on the Making Tax Digital for VAT systems. This could be due to either trying to submit too early or there's a problem at HMRC’s end.

To resolve this issue, try to log in to your HMRC business tax account. Your business tax account should display when your next return is due. If it doesn’t, contact HMRC for help.

Internal server error

The following error message "Internal server error" means HMRC’s system is currently having problems. If this happens, try submitting the return again.

This error could also mean that you’ve tried to file a Making Tax Digital return before you received the confirmation from HMRC that you successfully have signed up to MTD.

If you continue to encounter errors please contact HMRC, as there might be a problem with your records at HMRC’s end.
