I've just noticed that a client has forgot to adjust the FRS rate in their last VAT return (period ending Jan 11). Only one invoice applied at the new rate and the error only stands at a total of £13. Now, although this can be corrected in the next return, is it really worth writing to HMRC to consider a reduction in penalty of a careless error? I've read "The Light Touch" HMRC guidance, where they will be operating a 'light touch' in terms of errors made in the first VAT return after the change. Are they really interested in applying a penalty for £13???
