Lots of countries make a difference between income tax, and social contributions, the latter supposedly going to your pension or to your unemployment benefits. However, in reality they all go to the same government pot, and then the government can waste them in whatever way it likes, so I would count social contributions and income tax as pretty equivalent. Social contributions are in practice just income tax called something different.
There is one exception though and that is Singapore. There, residents are forced to pay a percentage of earnings into a Central Provident︀ Fund (CPF) , but it goes into segregated personal accounts that the government doesnt touch,︁ and then one can start accessing the personal CPF from 55 years of age.
The CPF existed under colonial times, but Lee Kuan Yew expanded it and made it a︂ pillar of the Singaporean social security system. Basically after realising what an utter disaster the︃ western welfare systems were, disincentivising hard work, promoting lazyness and creating poverty and misery.
