What is the HMRC API?

Article ID: 2607
Last updated: 14 Feb, 2023

When you authorise TaxCalc to connect to HMRC, we use a method of obtaining and submitting information called Application Programme Interface (APIs).

The API approach will see HMRC:

  • Promoting a ‘third-party software first’ approach for businesses and agents
  • Giving greater access to APIs
  • Sharing rules and logic
  • Publishing performance figures
  • Building richer APIs that enable third party products to work seamlessly with HMRC systems

HMRC have provided further documentation which can be found by clicking on the link for HMRC API

Please refer to our Knowledge Base articles for further guidance on specific APIs within TaxCalc:
