HMRC tax enquiries and compliance checks

Tax Investigation Services

Specialist support with HMRC tax enquiries, COP 9, disclosure cases, penalties, appeals and settlement discussions.

Take Advice Before Responding To HMRC

If HMRC has opened a tax enquiry, compliance check or disclosure case, take advice before sending explanations, figures or documents.

HMRC checks can involve personal tax, corporation tax, self assessment, partnerships, landlords, directors, offshore income, PAYE, VAT or suspected deliberate behaviour. The first response matters because unclear or incomplete information can lead to wider questions.
