VAT Find paid VAT when report already submitted to HMRC

Hi,

I already submitted a VAT return from 06/02/13 until 30/11/2013.

It was my first VAT return and I did it manually but I then found many invoices which I forgot to include.

How can I recalculate the VAT for this period to include the difference in the next VAT return?

I tried to rerun a VAT report but it won’t let me.

Thank you

If you add the missing invoices then they will automatically get brought forward into the next return so it should be self correcting. I would recommend checking the backing report before filing your next VAT return just to make sure.
