Dataset description

Paper containing information and analysis about reviews of, and appeals against, HMRC’s tax decisions. Where a customer disagrees with a decision made by HM Revenue & Customs (HMRC), they can ask for a review, make an appeal to an independent tribunal, or take both actions. Every year HMRC makes millions of decisions. Customers ask for reviews and make appeals in relation to only a small proportion of decisions. Information for previous years can be found on the National Archives website. (See additional links).

Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.

Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.

Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
