For the purposes of the Inland Revenue Regulation Act 1890 (c. 21) the definition of “inland revenue” in section 39 of that Act is to be taken to include tax credits.

The reference in section 4(1) of that Act (appointment of collectors, officers and other persons) to collecting, receiving, managing and accounting for inland revenue is to be taken to include a reference to paying and managing tax credits.

the amounts of the expenses of paying and managing tax credits, and
c
the amounts received by them in respect of tax credits,
distinguishing in each case between amounts relating to child tax credit and amounts relating to working tax credit.
6
In any declaration for the purposes of section 6 of the Taxes Management Act 1970 (c. 9) (declarations on taking office), whether made before or after the commencement of this section, the reference to an offence relating to inland revenue is to be taken to include a reference to an offence relating to a tax credit.

Where the amount of a tax credit paid for a tax year to a person or persons exceeds the amount of the tax credit to which he is entitled, or they are jointly entitled, for the tax year (as determined in accordance with the provision made by and by virtue of sections 18 to 21), the Board may decide that the excess, or any part of it, is to be repaid to the Board.

the amount of the difference, or of his entitlement or their joint entitlement, must be paid to him or to whichever of them is prescribed.
