[Daily Maverick] When tax-free savings accounts (TFSAs) were first introduced in South Africa in 2015, many criticised the small annual contribution limit of R30 000 (which was increased to R33 000 for the 2018 tax year and R36 000 for the 2021 tax year) and whether it would ever grow into a meaningful investment for investors. Unfortunately, as a result it has taken investors some time to embrace the material benefits of TFSAs.
