We are now receiving a numberr of P800T's for clients who have submitted SA100s. The figures are generally wrong because some untaxed income. often buiness income (S/Emp or partnership) is missing. We have in mind to send these back to HMRC refrrring them to the submitted SA100. Often the client has received a cheque and probally banked it. What are other practioners doing in such circumstances as the above is going to cause us extra work and probally some grief.
