Tax relief is granted to employees in respect of their contributions to occupational pension schemes approved by the Revenue Commissioners for the purposes of Section 6 of the Finance Act, 1972, and is also granted in respect of employee contributions to pension schemes established under public statute. Approved schemes may or may not require the members to make contributions towards the costs involved in providing the scheme benefits. Schemes may include provision for members to make voluntary contributions to increase their benefits within permitted limits. The maximum benefit that may be paid to a member of an approved scheme at normal retirement date is a pension of two-thirds of final remuneration.
