Client has missed £1,000 of VAT from the last 4 VAT returns. Does the facility to amend the next return to include the missed VAT only cover the latest return (as in, can I only correct £1,000 on the next return) or can it be errors from multiple returns (i.e. £4,000)?
Also, can you confirm your understanding of a further point. I am led to believe that doing the above does not constitute a disclosure, so HMRC could later say 'hang on, we've spotted errors of £4,000' and declare it unprompted? That seems to be the strict rule, but is it actually enforced like that? Basically, do I need to include the £4,000 AND do a seperate disclosure to HMRC (which seems to make the amending of the next return a pointless exercise)?
