The maxima that IR allows for tax relief purposes when paid into approved occupational pension schemes, personal pension plans and retirement annuities. Contributions to personal pension schemes including self-invested personal pensions and retirement annuity contracts are based on a scale of age-related percentages of net relevant earnings (17.5 per cent for persons aged 35 or less up to 40 per cent for age 61 and over). Contributions to approved occupational scheme members are limited to a maximum of 15 per cent of taxable remuneration in any year regardless of age. This limit remains unchanged when contributing concurrently to a personal pension or stakeholder plan (contributions to stakeholder pensions are limited to £3,600 irrespective of age (2002/3)). Except for retirement annuity contracts, all contributions are subject to the earnings cap. There are no limits on employers’ contributions other than those required to ensure that benefits remain inside IR maxima. See CONCURRENCY.
