asked Her Majesty's Government:

Whether the tax returns and records of members of the House of Lords are subject to the same level of security by HM Revenue and Customs as those of members of the House of Commons. [HL1655]

HM Revenue and Customs (HMRC) applies high standards of confidentiality and security to all customer data. Additional safeguards may be provided, within HMRC, for the records of members of the House of Lords, depending on their personal circumstances.
