The responsibility to comply with the self assessment regime rests solely with the individual taxpayer. This means that self assessment tax return forms have to be 100% correct, each entry therein is to be supported by documentary evidence and the return must be submitted on time. Failure to do this will result in punitive penalties, surcharges and interest. We have the expertise and the I.T.systems to prepare self assessment return forms and submit them electronically to HM Revenue & Customs.
