For the purposes of benefit crystallisation event 2 “P” is the amount of the pension which will be payable to the individual in the period of 12 months beginning with the day on which the individual becomes entitled to it (assuming that it remains payable throughout that period at the rate at which it is payable on that day).

If the pension is under a public service pension scheme, any abatement of the pension is to be left out of account in determining the amount of the pension which will be payable for the purposes of sub-paragraph (1).

If the amount of the pension which will be payable F2is reduced so as to reflect the amount of any tax under section 215 to be paid by the scheme administrator, that reduction is to be left out of account in determining the amount of the pension F3... for the purposes of sub-paragraph (1).

And if the reduction is such that, in accordance with normal actuarial practice, it would be taken fully to reflect the amount of the tax, the tax is not to be treated as tax paid by the scheme administrator for the purposes of section 215(9).
