SRS is meant to help individuals to save part of their income for their retirement, on top of their CPF contributions, and should not become a tax shelter for the asset-rich or high-income individuals. There is hence a cap on the SRS contributions. The 15% cap for locals contributions was decided after a public consultation in the early part of year 2000. The absolute income base is similar to that for CPF contributions (i.e. capped at $85,000 per annum from 1 January 2011, to be raised to $102,000 per annum from 1 January 2016).
