i Short answer
A retirement annuity gives you a tax deduction today, up to 27.5% of income capped at R430,000 a year, and grows untaxed. The cost is access: the money is locked until age 55, restricted by Regulation 28, and taxed as income when you draw it in retirement.
A tax-free savings account gives no deduction, so you contribute after-tax money, but nothing inside is ever taxed and you can withdraw at any time. For most people the answer is not one or the other: use the RA where your marginal rate makes the deduction valuable, and the TFSA for flexibility and genuinely tax-free growth.

RA vs TFSA: The Numbers
The RA deduction cap rose from R350,000 to R430,000 on 1 March 2026. The 27.5% rule is unchanged, so most people are limited by the percentage rather than the rand cap.
1. The core difference in one paragraph
Both are tax wrappers rather than investments, and you choose what goes inside each. The difference is when the tax relief happens. A retirement annuity gives relief on the way in, through a deduction that reduces this year's taxable income, and then taxes the income when you draw it decades later. A tax-free savings account gives no relief on the way in, but nothing inside is ever taxed and withdrawals are free of tax entirely.
Both grow without tax on interest, dividends or capital gains while invested, so the growth phase is identical. Everything that differs is at the two ends: what happens when money goes in, and what happens when it comes out.
2. How a retirement annuity actually works
Contributions to a retirement annuity are deductible under Section 11F of the Income Tax Act, up to 27.5% of the greater of your remuneration or taxable income, capped at R430,000 a year from 1 March 2026. That cap rose from R350,000; the 27.5% rule did not change.
Critically, the limit is shared across all your retirement funds combined. If you already contribute to a workplace pension or provident fund, those contributions count toward the same 27.5%, and only the remaining room is available for a personal RA. Contributions above the limit are not lost: SARS carries the excess forward to future years or offsets it at retirement.
The deduction is the headline attraction and it is genuinely large. Someone in the 39% bracket contributing R50,000 reduces their tax bill by around R19,500, which they receive back through their assessment. Why the cap increased to R430,000 covers the change, and the retirement annuity calculator estimates the effect at your income.
3. How a tax-free savings account works
You contribute money on which you have already paid income tax, and in exchange nothing inside is taxed again. No dividend withholding tax, no tax on interest, no capital gains tax on sale, and no tax on withdrawal, at any age, for any reason.
The limits are R46,000 a year from 1 March 2026 and R500,000 over your lifetime. Three rules govern them and all three catch people out. Unused annual room does not carry forward. Contributions above the limit are penalised at 40% of the excess. And withdrawing does not restore contribution room: take R50,000 out and put it back, and you have used R50,000 of your lifetime allowance twice.
This is the most commonly misunderstood rule. A TFSA is accessible, which makes it feel like a flexible savings account, but every rand withdrawn and replaced consumes lifetime allowance twice over. Access and replenishment are different things.
Because the R500,000 lifetime cap never refreshes, what goes inside matters more than in any other wrapper. Room used on a cash or money market product is room permanently unavailable for growth assets, and growth assets held for decades are where the shelter is worth most. What you can hold in a TFSA covers eligibility, and the TFSA calculator tracks contributions across providers.
4. Side by side, on the points that matter
| Feature | Retirement annuity | Tax-free savings account |
|---|---|---|
| Tax relief on contribution | Yes, up to 27.5% capped at R430,000 | None |
| Growth taxed | No | No |
| Tax on withdrawal | Yes, as income in retirement | None, ever |
| Access before 55 | Only via the two-pot savings component | Anytime |
| Contribution limit | 27.5% of income, R430,000 a year | R46,000 a year, R500,000 lifetime |
| Investment restrictions | Regulation 28 applies | None beyond product eligibility |
| Withdrawal restores room | Not applicable | No |
| Protected from creditors | Generally yes | No |
Two rows deserve emphasis. Regulation 28 caps a retirement fund at 75% equities, 45% offshore and 25% property, which limits how aggressively an RA can be invested. A TFSA has no such restriction, which makes it the natural home for the higher-equity, higher-offshore portion of a long-term portfolio. Regulation 28 and offshore limits covers those caps.
5. Your marginal rate usually decides it
The RA deduction is worth exactly your marginal rate. At 18% it returns R180 on every R1,000 contributed; at 45% it returns R450. The higher your bracket, the more the deferral is worth, and the more likely it is that your retirement tax rate will be lower than your rate today.
If you already contribute to a workplace pension fund, check how much of the 27.5% is already used before opening an RA. Many employees discover their employer contributions consume most of the available room, which changes the calculation entirely.
6. Access, Regulation 28 and the two-pot system
The RA lock-up until 55 is a feature rather than a defect, but it is a real constraint. Money you might need for a house deposit, a business or an emergency should not be in an RA at any marginal rate.
The two-pot system softened this. Contributions now split between a savings component, which permits limited withdrawals before retirement, and a retirement component, which stays locked. Withdrawals from the savings component are taxed at your marginal rate and reduce your eventual retirement capital, so the access exists but is expensive. Using a two-pot withdrawal for trading capital covers why that particular use is rarely a good idea, and repeat two-pot withdrawals covers the pattern that has emerged.
Regulation 28 is the other constraint. Capping equities at 75%, offshore at 45% and property at 25% is prudent for a fund someone will retire on, but it prevents the higher-equity allocation that a young investor with thirty years ahead might reasonably want. The usual resolution is to take the higher-growth allocation in the TFSA and discretionary accounts, where no such caps apply.
7. The tax you pay at the other end
This is the part most comparisons skip, and it is where the deferral is settled. At retirement you may take up to one third of an RA as a lump sum, taxed on the retirement lump sum table with a portion tax free, and the remainder must buy an annuity that pays you an income taxed at your marginal rate.
| Stage | Retirement annuity | TFSA |
|---|---|---|
| Lump sum available | Up to one third | All of it |
| Lump sum taxed | Per the retirement lump sum table | Not taxed |
| Remaining capital | Must buy an annuity | No requirement |
| Ongoing income taxed | At your marginal rate | Not taxed |
| On death | Distributed by trustees under the Pension Funds Act | Forms part of your estate |
So the RA's advantage depends on the gap between your tax rate now and in retirement. If you contribute at 45% and draw income at 26%, the deferral is a large, real gain. If you contribute at 26% and draw at 26%, you have deferred rather than avoided, and given up access for decades in exchange. Taking a lump sum versus an annuity covers that decision.
8. A practical way to sequence both
For most people this is not a choice between two products but a question of order. The sequence below is a common framework rather than personal advice, and your own circumstances may change it.
- Capture any employer retirement fund match first; it is an immediate return nothing else matches
- Clear high-interest debt, which beats both wrappers on a guaranteed basis
- Hold an emergency buffer outside both, since neither should be your liquidity
- If your marginal rate is high, use RA room up to the deduction you actually value
- Fill TFSA room with growth assets, especially offshore equity that Reg 28 would cap
- Keep anything needed before 55 in a discretionary account, not an RA
★ Why It Matters
The wrappers are complementary rather than competing, and the debate about which is better usually obscures that. The RA answers a tax question this year; the TFSA answers a tax question over forty. Because the TFSA's lifetime limit never refreshes and the RA's allowance resets annually, delaying TFSA contributions costs room you can never recover, while delaying RA contributions costs only that year's deduction.
✕ Common mistakes
- Forgetting employer contributions share the 27.5% limit. Workplace pension contributions use the same allowance as your personal RA.
- Withdrawing from a TFSA and replacing the money. Withdrawals do not restore room, so the lifetime cap is consumed twice.
- Filling TFSA room with cash. The wrapper is worth most on growth assets held for decades.
- Putting money needed before 55 into an RA. Two-pot access exists but is taxed at your marginal rate and shrinks your retirement capital.
- Ignoring Regulation 28 caps. A young investor wanting heavy equity and offshore weight will hit them inside an RA.
- Comparing the RA deduction without the exit tax. The deduction is deferral, and the gain depends on the gap between your rate now and in retirement.
Key Takeaways
- An RA defers tax and a TFSA eliminates it: the RA gives relief on contribution and taxes withdrawals, the TFSA does the reverse.
- RA contributions are deductible up to 27.5% of the greater of remuneration or taxable income, capped at R430,000 a year from 1 March 2026.
- The 27.5% limit is shared across all retirement funds, so workplace pension contributions reduce the room available for a personal RA.
- TFSA limits are R46,000 a year and R500,000 for life, unused annual room does not carry forward, and excess contributions are penalised at 40%.
- TFSA withdrawals do not restore contribution room, so money taken out and replaced consumes the lifetime allowance twice.
- Regulation 28 caps a retirement fund at 75% equities, 45% offshore and 25% property; a TFSA has no such restrictions.
- The RA deduction is worth your marginal rate, so it favours higher earners, while the TFSA's permanent exemption favours lower brackets and long horizons.
- Retirement fund assets are generally protected from creditors under the Pension Funds Act, which a TFSA does not offer.
Frequently asked follow-up questions
Should I open a retirement annuity or a TFSA first?
It depends mainly on your marginal tax rate and when you need the money. High earners usually get more from the RA deduction, which returns 39% to 45% of each contributed rand, while those in lower brackets often get more from the TFSA's permanent exemption. Money you might need before age 55 should not go into an RA at any rate.
How much can I contribute to a retirement annuity tax-free?
You can deduct up to 27.5% of the greater of your remuneration or taxable income, capped at R430,000 a year from 1 March 2026. The limit applies across all your retirement funds combined, so workplace pension or provident contributions use the same allowance. Contributions above the limit carry forward to future years.
What is the TFSA limit for 2026?
R46,000 a year from 1 March 2026, up from R36,000, with a lifetime limit of R500,000 that has not changed. Unused annual room does not carry forward to the next year, and contributions above the limit attract a penalty of 40% of the excess.
Can I withdraw from a TFSA and put the money back?
You can withdraw at any time without tax, but replacing the money uses fresh contribution room. Withdrawals do not restore either the annual or lifetime allowance, so taking R50,000 out and putting it back consumes R100,000 of your R500,000 lifetime cap in total.
When can I access money in a retirement annuity?
Normally from age 55. The two-pot system created a savings component that permits limited earlier withdrawals, but those are taxed at your marginal rate and permanently reduce your retirement capital. The retirement component remains locked until retirement age.
What is Regulation 28 and how does it affect my RA?
It is a prudential rule limiting how retirement funds may be invested: a maximum of 75% in equities, 45% offshore and 25% in property. It applies to RAs, pension and provident funds but not to a TFSA or a discretionary account, which is why many investors take their higher-equity and offshore allocation outside the retirement wrapper.
Is an RA taxed when I retire?
Yes. You may take up to one third as a lump sum, taxed according to the retirement lump sum table with a portion tax free, and the remainder must purchase an annuity whose income is taxed at your marginal rate. This is why the RA is a deferral: the benefit depends on your retirement rate being lower than your rate today.
Can I have both an RA and a TFSA?
Yes, and for many people using both is the sensible arrangement. They have separate limits and serve different purposes: the RA reduces this year's tax bill and locks money for retirement, while the TFSA provides accessible, permanently untaxed growth with no investment restrictions.
Which is better for someone in their twenties?
The TFSA often works harder at that stage, for two reasons. Marginal rates are usually lower early in a career, which makes the RA deduction less valuable, and the lifetime TFSA cap never refreshes, so every year of unused room is permanently gone. Decades of untaxed compounding inside the wrapper is where its value concentrates.
Are RA and TFSA assets protected if I am sued or go insolvent?
Retirement fund assets, including RAs, generally receive protection from creditors under the Pension Funds Act. Tax-free savings accounts do not carry that protection and form part of your estate. For business owners or anyone who has signed personal surety, that difference can matter as much as the tax treatment.
