HMRC (His Majesty’s Revenue and Customs) is the UK government department responsible for tax collection, administration, and enforcement. HMRC stores records on employment income you have received and where you received it from, which Konfir requests access to complete your verification.
Government Gateway is the name of your online account which is used to access your HMRC records (in addition to other government services). By logging in to your Government Gateway, you authorise Konfir to access the HMRC records required to complete your employment or income verification.
