Part C Teachers' Contributions

C1 Salary on which contributions are payable
1 Subject to paragraphs (2) to (12), a person’s contributable salary is the total of—
(a) the amounts payable by his employer, in respect of his pensionable employment—
(i) by way of salary; and
(ii) in satisfaction of any statutory liability arising out of sickness or maternity; and
(b) if the employer has satisfied the Department that it is expedient for residential accommodation to be provided free in connection with the employment, the money value as an allowance in kind of—
(i) the accommodation provided; and
(ii) any heating or lighting provided free in connection with such accommodation.
2 Where a person’s contributable salary is reduced due to maternity leave or adoption leave the employee’s contributions shall be based on the actual rate of salary paid and the employer’s contributions shall be based on the notional rate as defined in paragraph (6).
3 If the money value of any accommodation provided, as mentioned in paragraph (1)(b)(i), exceeds one sixth of the amounts mentioned in paragraph (1)(a), the excess is not part of the person’s contributable salary.
4 A person’s contributable salary does not include—
(a) any allowance in kind not falling within paragraph (1)(b);
(b) any payment in respect of overtime;
(c) any payment by way of travelling or expense allowance; or
(d) any payment by way of bonus.
5 For the purposes of paragraph (4)—
(a) a payment by way of bonus shall not include any payment calculated by reference to the performance of the person in question or the performance of the institution where he is employed;
(b) a payment by way of bonus shall not include any payment made to the person in question where such a payment is made as part of a pay settlement which applies to all persons, or to all persons of a particular class or description, employed at the institution;
(c) if at any time a payment is made to a person which is not part of his contributable salary then any subsequent payment of the same nature is a payment by way of bonus (whether or not it is described as such); and
(d) if at any time a payment is made to a person which is part of his contributable salary then any subsequent payment of the same nature is not a payment by way of bonus (whether or not it is described as such).
6 A person who continues in full-time pensionable employment but whose contributable salary is reduced, otherwise than by reason of sick leave, adoption leave or maternity leave, may elect that it is to be treated as having continued at the rate applicable immediately before the reduction (“the notional rate”).
7 An election for the purposes of paragraph (6)—
(a) shall be made by giving written notice to the Department within 3 months after the reduction;
(b) has effect from the day after the last day on which the person’s salary was payable at the rate applicable before the reduction; and
(c) subject to paragraph (9), continues to have effect until a relevant event occurs in relation to the person who made it.
8 For the purposes of paragraph (7)(c) the relevant events in relation to any person are—
(a) the actual rate at which the salary is paid exceeds the notional rate;
(b) that person enters employment as a temporary teacher or part-time pensionable employment; and
(c) unless he elects to pay additional contributions under regulation C6 or C7, that person ceases to be in pensionable employment.
9 An election made for the purposes of paragraph (6) may be cancelled by giving written notice to the Department at any time.
10 Notice of cancellation under paragraph (9)—
(a) has effect from the first day of the month following that in which it was received; and
(b) is irrevocable.
11 If, while an election made for the purposes of paragraph (6) has effect there is any further reduction during a period of sick leave, adoption leave or maternity leave, the notional rate shall, during that period, be treated as having been reduced in the same proportion as the actual rate.
12 Subject to paragraphs (13) and (14), in the case of a person entering pensionable employment after 31st May 1989 with no right to count any period before 1st June 1989 as reckonable service, in any tax year in which the contributable salary calculated in accordance with paragraphs (1) to (11) exceeds the permitted maximum in terms of section 590C of the Income and Corporation Taxes Act 1988 (earnings cap), the excess does not form part of his contributable salary.
1988 c. 1; section 590C was inserted by the Finance Act 1989 (c. 26) Schedule 6, paragraph 4
13 Paragraph (12) shall not apply to a person—
(a) who was in pensionable employment before 1st June 1989 and who resumes pensionable employment following—
(i) an absence on maternity leave in respect of which she enjoyed a right to return to work under Articles 111 to 117 of the Employment Rights (Northern Ireland) Order 1996;
S.I. 1996/1919 (N.I. 16)
(ii) a period of secondment or additional period of absence necessarily attributable to that secondment; and
(iii) in any other case, a break in pensionable employment not exceeding one year; or
(b) who was in comparable service before 1st June 1989 and who enters pensionable employment provided there has not been a period of more than one year between cessation of employment in comparable service and entering pensionable employment.
14 For the purpose of paragraph (13), “comparable service” does not include service which is pensionable under a superannuation scheme for teachers in public employment in the Channel Islands or the Isle of Man.

(a) if on the date of his death he had ceased to be in pensionable employment he would have become entitled under regulation E4 to payment of retirement benefits; and
(b) another person (“the pensioner”) is entitled under regulation E26 to a long-term pension in respect of him.
2 Where this regulation applies the pensioner, or in the case of a child, a person acting on his behalf, may, by giving written notice to the Department within 3 months after the death, make any election which, on the hypothesis stated in paragraph (1)(a), the deceased person could have made under regulation C3.

C7 Additional contributions for current period: service in a reserve force
1 This regulation applies to a person who ceases to be in pensionable employment by virtue of being called out or recalled for permanent service in Her Majesty’s armed forces in pursuance of a call-out notice or call-out order or a recall order made under the provisions of the Reserve Forces Act 1996, provided that—
(a) the person does not apply for payment of any retirement benefits to which he would otherwise be entitled on ceasing to be in such employment; and

2 Subject to paragraphs (10) and (11), a person to whom this regulation applies may elect to pay additional contributions in order to become entitled to count as reckonable service a period (“the period”) beginning on the day after the cessation of the pensionable employment and ending with the date on which he is released from permanent service or discharged.
3 An additional contribution is payable for each financial year and is 6% of the notional salary for so much of the period as falls within that year.
4 For the purposes of paragraph (3), the notional salary is the salary that would have been payable if pensionable employment had not ceased and the person had continued to be employed in the same post and on the same terms.
5 Subject to paragraphs (7) and (8), an election under this regulation shall be made by giving written notice to the Department and shall be given at any time between the cessation of pensionable employment and 6 months after the return to pensionable employment after the end of the period.
6 An election has effect only if any contribution under this regulation is paid by the person to the Department within three months of the date of a written notification by the Department that payment is due to it; and provided that the person pays all contributions and payments payable by him in respect of the period in accordance with an election or elections made by him under regulation C3 (taken with Schedule 4), regulation C8 (taken with Schedule 6) and regulation C13.
7 Where an election is made before the end of the period it shall specify the day on which the period begins; and where an election is made after the end of the period it shall specify the period.
8 Subject to paragraph (9), where the person dies during his service in a reserve force without having made an election under this regulation, he shall be deemed to have made such an election so that the period beginning with and including the day after the cessation of the pensionable employment and ending with the date of his death shall count as reckonable service.
9 Any contribution due under this regulation at the date of such death shall be deducted from any benefits payable under these Regulations.
10 Notwithstanding that a person to whom this regulation applies has not made an election under this regulation, he shall be entitled to count the period as reckonable service where during the period his service pay, when aggregated with any payments under Part V of the Reserve and Auxiliary Forces (Protection of Civil Interests) Act 1951, is less than the remuneration he would have received if he had during the period continued in the pensionable employment in which he was employed immediately before being called into service in a reserve force.

(a) as having remained in such employment while she enjoyed the right to return to work conferred by Articles 111 to 117 of the Employment Rights (Northern Ireland) Order 1996; and
(b) if she has exercised that right, as not having ceased to be in pensionable employment.
4 Subject to regulation C12 (application for repayment), where this regulation applies the person is entitled to be repaid the balance of his contributions, calculated in accordance with regulation C10.

(c) if the person was entitled to count any reckonable service by virtue of the receipt of a transfer value in respect of an employment that was not comparable service, either—
(i) any payment by way of repayment of contributions, and interest, that he would otherwise have been entitled to receive under the rules of the superannuation scheme to which he was subject in the employment; or
