How Much to Contribute to a Retirement Annuity

Once you understand what a retirement annuity is and how its tax treatment works, a harder question follows: how much goes in? A single number is tempting, but the amount depends less on a figure and more on how a retirement annuity fits with everything else you’re trying to do with your money. If you’re still getting to grips with the basics, the beginner’s guide to retirement annuities covers them, and this article picks up from there.

The tax deduction has a cap

South Africa’s tax system doesn’t allow unlimited contributions to be deducted. The limit is a percentage of your income up to an annual ceiling. Contributions within it are generally tax-deductible. Contributions above it can still be made, but the excess doesn’t earn the deduction in that year and is carried forward to later years.

The percentage and the rand ceiling are set in tax law and published by SARS, and they can change, so this article doesn’t quote numbers. Confirming the current figures with SARS or a qualified adviser before planning around them is worthwhile. Conceptually, the limit marks the point where the annual deduction stops. It says nothing about how much any one person is saving or needs to save: it caps the tax break and is not a savings goal handed down from the tax office.

Contributing up to the limit involves trade-offs

Because the deduction has real value, contributing right up to the limit each year can look like the obvious route. Whether it fits depends on the trade-off that comes with a retirement annuity in the first place.

Most of the money inside a retirement annuity is preserved until a qualifying retirement age. Since the two-pot system began on 1 September 2024, part of each new contribution (the savings component) can be reached earlier, a limited number of times a year, but what you take is taxed as income and reduces your retirement savings. Money saved before that date sits in a vested component under the old rules. That limit on access is the price of the tax benefits, and it means most of what you commit is hard to reach if life takes an unexpected turn. One thing to weigh is what happens if the deduction is maximised while little accessible saving remains: the tax saved on the way in does not help much if expensive borrowing, or a taxed withdrawal from retirement savings, follows because other money is out of reach.

Other calls on your money: liquidity, debt and nearer-term goals

Before committing money for decades, it helps to ask what else that money needs to do. Three things are worth weighing alongside a larger retirement annuity contribution:

• An emergency fund. Is there accessible money to draw on without penalty if an unexpected cost arrives? Retirement money plays that role poorly, because most of it can’t be reached, and the part that can is taxed as income and reduces your retirement savings.
• Expensive debt. What does high-cost borrowing cost each month, and how does that compare with the tax saving from a larger contribution? Clearing debt frees up income, which changes how much is left to commit to long-term saving.
• Nearer-term goals. Money needed within a few years sits awkwardly with something that preserves most of it until retirement, whatever the tax treatment. Is any of this money likely to be needed sooner?

None of this ranks a retirement annuity below these items. It does mean that the amount available to commit for the long term depends on how the shorter-term needs are met. A retirement annuity is also one part of a wider plan rather than the whole of it, and a tax-free savings account, compared with a retirement annuity, is one accessible option that can sit alongside it.

The amount can change over a career

Whatever amount looks workable today may look different later. The capacity to commit money to retirement shifts with the stages of a working life. Early on, income can be lower and other demands (debt, setting up a home, young children) higher, so a modest contribution that can be sustained may be easier to keep going than an ambitious one that can’t.

As income grows and some of those earlier pressures ease, there may be more room to increase what goes in, while less time remains before retirement. A contribution doesn’t have to be set once and left alone. It can be revisited whenever circumstances change materially: a pay rise, a change in family situation, clearing a big debt, or simply the passing of years. Treating the amount as something reviewed, rather than a fixed commitment, keeps it in step with a whole career.

Questions to weigh

Pulling it together, the question moves from “what’s the maximum?” to a short sequence of others:

• Do I have accessible savings and manageable debt, so that committing to retirement saving won’t leave me stretched?
• Of what’s left, how much can I realistically commit for the long term without wanting it back?
• Where does the tax-deduction limit sit relative to that amount: is the deduction shaping a decision I’d make anyway, or tempting me past what I can comfortably commit?
• When will I next revisit this, given how my income and responsibilities are likely to change?

Different people will answer those questions differently, and the answers tie the amount to a life rather than to a cap. How a retirement annuity sits alongside accessible savings, offshore diversification where it’s relevant, and everything else is covered in general terms on the onshore page.

Frequently asked questions

Is there a limit on how much I can contribute to a retirement annuity?

There is a limit on how much of your contribution can be deducted from tax each year. It is set in tax law and published by SARS as a percentage of income up to an annual ceiling. Contributions above the cap are still possible, but only the amount within it earns the deduction that year, and the excess is carried forward. The figures can change, so confirm the current ones with SARS or a qualified adviser.

What else is worth weighing before contributing the maximum the tax break allows?

The deduction has value, but most of the money in a retirement annuity is preserved until a qualifying retirement age, and the part that can be reached earlier is taxed as income and reduces retirement savings. Without an emergency fund, or while carrying expensive debt, a tax saving can be outweighed by costs elsewhere. The amount that can realistically be committed for the long term once other needs are met is the figure to set against the cap.

How does contributing to a retirement annuity compare with a tax-free savings account?

A retirement annuity gives a deduction on contributions now but preserves most of the money until retirement, with a limited part reachable earlier under the two-pot system and taxed as income. A tax-free savings account has a different tax benefit and allows access to the money at any time. Some people hold both, and how much goes into each depends on how much accessible saving is needed.

Can the amount I contribute to a retirement annuity change over my career?

What can be set aside for retirement shifts as income, debt, family responsibilities and the time to retirement change. A contribution can start modestly, rise as income grows and obligations ease, and be reviewed whenever circumstances change materially. The rules for changing it depend on the terms of the specific retirement annuity.
