A client's employment income for a tax year under MTD Income Tax: the employments themselves, the financial details held against each, and the income belonging to no single employment (non-PAYE tips, share schemes, lump sums, deductions). Employments come from two places and what can be done to them differs: one HMRC hold from the employer's RTI submissions cannot be edited or deleted, only ignored, while a custom employment added here can be amended and deleted but never ignored.

Amend Custom Employment

PUT /tenants/{tenant}/clients/{client}/mtd/employments/{taxYear}/{employmentId}

Amends a custom employment — a full replacement of its record, so every value that should survive must be present. HMRC refuse this for an employment they hold themselves: that is the employer's record, and ignoring it is the way to take it out of the calculation.
