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 the following information about an individual's income for a given tax year:

income from employment, as reported to HMRC by their employers through the PAYE process
income from pensions (other than state pension) and retirement annuities
income from other state benefits or grants, such as taxable Incapacity Benefit, contribution-based Employment and Support Allowance and the Self-Employment Income Support Scheme

The primary intended use for this information is to pre-populate an individual's Self Assessment tax return.

You can use the sandbox environment to test this API.

Why do these endpoints look different?

The endpoints for this API now use the Open API Specification (OAS).

The API has not changed. You do not need to make any updates to your application if you already use this API.
