Let me start with the most important word in this article: legal.
There's a meaningful difference between tax evasion and tax planning. Evasion is hiding income, inflating expenses, and lying to SARS. It's illegal, and it ends badly. Tax planning is using the deductions, allowances, and exemptions that the law deliberately provides to encourage saving, investing, and giving. One lands you in trouble. The other is exactly what the tax code was designed for.
Here's the uncomfortable truth: most South Africans overpay their tax. Not because they've done anything wrong, but because they never use the legal levers available to them. They leave money on the table every single year, money that could have been in their retirement fund, their family's pocket, or a cause they care about.
These are five of the most effective, completely legal ways to reduce your tax bill for the 2026/27 tax year (1 March 2026 to 28 February 2027). None of them are loopholes. All of them are SARS-sanctioned.
1. Max out your retirement fund contributions
This is the single biggest lever most people have, and it's staggering how many don't pull it.
Contributions to a retirement annuity, pension fund, or provident fund are tax-deductible, up to 27.5% of the greater of your taxable income or remuneration, capped at R430,000 per year (increased from R350,000 for the 2027 tax year). Every rand you contribute within that limit reduces your taxable income, which reduces the tax you pay.
A practical example: if you earn R600,000 a year and contribute R60,000 to a retirement annuity, you don't pay tax on that R60,000. At a marginal tax rate of, say, 36%, that's roughly R21,600 back in your pocket, while the full R60,000 stays invested and growing for your future. You're not spending the money; you're moving it from SARS into your own retirement, and getting a tax break for doing it.
If you contribute more than the annual limit, the excess isn't lost either, SARS carries it forward to future tax years, or offsets it against tax when you eventually retire.
2. Use your Tax-Free Savings Account
The Tax-Free Savings Account (TFSA) works differently from a retirement annuity, the contribution itself isn't deductible, but what happens inside it is powerful.
You can contribute up to R46,000 per year (increased from R36,000 as of 1 March 2026), with a lifetime limit of R500,000. Every cent of growth inside a TFSA, interest, dividends, and capital gains, is completely tax-free, forever. No tax on the way out, no matter how large it grows.
Over a long horizon, that compounding-without-tax effect is enormous. A TFSA started early and left to grow for 20 or 30 years can shelter hundreds of thousands of rands in gains from tax entirely. It's one of the best long-term wealth-building tools available to ordinary South Africans.
Two warnings: don't exceed the annual limit, SARS taxes over-contributions at a punishing 40%, and treat it as a long-term investment, not a savings pot you dip into, because withdrawals permanently use up your lifetime allowance.
3. Claim every medical tax credit you're entitled to
If you belong to a medical scheme, you're entitled to the Medical Scheme Fees Tax Credit, a fixed monthly credit that reduces your tax directly (not just your taxable income). For the 2026/27 tax year, that's R376 per month for each of the first two members, and R254 per month for each additional dependant.
For a family of four on a medical scheme, that adds up to over R15,000 a year knocked straight off your tax bill. Most people on a scheme get this automatically, but it's worth checking your assessment to confirm it's being applied.
The piece people miss is the Additional Medical Expenses Tax Credit. If you have significant out-of-pocket medical costs that your scheme didn't cover, or if you have a disability in the family, a portion of those expenses can generate an additional credit above the standard one. This requires keeping records and claiming properly, and it's exactly the kind of thing a good tax practitioner will pick up that you might miss on your own.
4. Give to registered charities, and claim it
If you donate to a registered Public Benefit Organisation (PBO) that can issue a Section 18A certificate, your donation is tax-deductible, up to 10% of your taxable income.
This is a rare win-win in the tax code: you support a cause you care about, and you reduce your tax bill for doing it. The critical detail is the Section 18A certificate, not every non-profit can issue one, and without it, SARS won't allow the deduction. Always ask the organisation for their 18A certificate before assuming a donation is deductible, and keep it for your records.
If your giving in a year exceeds the 10% limit, the excess carries forward and can be claimed in the following tax year.
5. Use your annual exemptions and allowances
Beyond the big-ticket items, the tax code gives every individual a set of annual exemptions that quietly reduce what you owe, if you actually use them.
The interest exemption. Interest earned from South African sources is tax-free up to R23,800 per year if you're under 65, and R34,500 per year if you're 65 or older. Structuring where you hold your cash so you make use of this exemption is a simple, legitimate saving.
The capital gains annual exclusion. The first R50,000 of your net capital gains each year is excluded from capital gains tax (increased from R40,000 in the 2026 Budget). Spreading the disposal of assets across tax years, rather than realising everything in one, can keep you within your annual exclusions and materially reduce CGT.
If you're self-employed or run a business: legitimate business expenses, a properly qualifying home-office deduction, and travel claims (with an accurate logbook) all reduce your taxable income. The rules here are specific and SARS scrutinises them closely, so this is an area where getting professional guidance pays for itself many times over.
The timing point most people miss
Almost all of these levers work on the tax year, 1 March to 28 February. That means the time to act is before the end of February, not in a panic when you're filing months later. A retirement annuity top-up made on 27 February counts for that tax year; the same top-up made on 2 March counts for the next one.
The most tax-efficient people aren't doing anything exotic. They're simply using the ordinary, legal mechanisms consistently and on time, every year, not as an afterthought.
Where to start
You don't need all five working at once to make a difference. For most people, simply maximising retirement fund contributions and using a TFSA properly captures the majority of the benefit. From there, medical credits, giving, and annual exemptions add up.
If you'd like to work out which of these apply to your situation, and roughly what they're worth to you, book a free 30-minute call. For anything involving your specific tax return, a registered tax practitioner should be part of the conversation; I work alongside good ones and can point you in the right direction.
Paying your fair share is part of living in a functioning society. Paying more than the law asks of you, year after year, simply because nobody showed you the levers. That's the part worth fixing.
