Tax Investigation Advice

If you have reached our tax investigation advice page then it probably means one of three things:

If you have not received an HMRC letter, but are concerned that you may have unpaid taxes, then please visit our page on making an HMRC voluntary disclosure


Contact will usually come from an HMRC local compliance team. The opening HMRC letter will be headed Check of Self Assessment Tax Return; alongside the relevant tax year of years. HMRC will usually write to you informing you that a check of self assessment tax return has commenced when they feel tax is at risk. The letter will ask you to supply relevant information and/or records that HMRC consider to be reasonably required to check your position. You simply must seek specialist tax investigation advice before complying with HMRC requests for information and documents.  You can read detailed information on supplying records during an HMRC compliance check by visiting our news blog dealing with HMRC compliance check – requests for information and documents.


You may have received notice that HMRC suspect serious fraud and that you are now the subject of investigation under the code of practice 9 procedures. Cases conducted under this provision require very specialist tax investigation advice

For detailed tax investigation advice on code of practice 9 and HMRC’s approach when dealing with civil investigation of fraud,  please select the relevant tax service from the list below.
