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 tax record for a given year:
- tax deducted from annual gross income for a given employment and tax year
- tax deducted from pensions (other than state pension) and/or retirement annuities
- tax deducted from Incapacity Benefit
- tax refunded, or set off, within this tax year. For example; a repayment of CIS deductions (if you work in the construction industry), PAYE tax or tax paid on savings income. It may also be an amount that HMRC has reallocated to an existing debt.
The primary intended use for this information is to pre-populate an individual's Self Assessment tax return.
