Overview
This API is one of a number of APIs that provide information that HMRC knows about an individual's tax affairs.
This API in particular provides information about an individual's history of employment for a given tax year, as reported to HMRC by their employer(s) through the PAYE process. The history of employment mainly contains details like Employer Paye Reference, Employer's name and Off Payroll Workflag (if available).
The primary intended use for this information is to pre-populate an individual's Self Assessment tax return.
Errors
We use standard HTTP status codes to show whether an API request succeeded or not. They are usually in the range:
- 200 to 299 if it succeeded, including code 202 if it was accepted by an API that needs to wait for further action
- 400 to 499 if it failed because of a client error by your application
- 500 to 599 if it failed because of an error on our server
Errors specific to each API are shown in the Endpoints section, under Response. See our reference guide for more on errors.
Testing
You can use the sandbox environment to test this API.
It supports stateful behaviour. You can set up test data using the Individual PAYE Test Support API.
Versioning
When an API changes in a way that is backwards-incompatible, we increase the version number of the API. See our reference guide for more on versioning.
