Why a TFSA is so powerful

A Tax-Free Savings Account shelters all interest, dividends, and capital gains from South African tax. Over a 30-year horizon, the tax saving alone often doubles your final balance compared to an equivalent taxable account.

Key rules

  • R36 000 maximum contribution per tax year (1 March – 28 February).
  • R500 000 lifetime contribution cap, across all your TFSAs combined.
  • Excess contributions are taxed at 40% by SARS — automatic, no opt-out.
  • Withdrawals do not restore your contribution room.
  • You can hold multiple TFSAs but the limits apply across all of them.
