South African retirement tax trap

South Africans with unused retirement contributions could lose valuable tax savings if they use them incorrectly, with the balance potentially worth up to 45% in tax relief, depending on how it is applied.

This is according to Shepstone & Wylie Partner Chrichan de la Rey and Senior Associate Daniel Robb, who examined how taxpayers can get the most value from excess contributions to retirement funds.

Many taxpayers contribute more to retirement funds than they can deduct in a particular year. While the unused amount is carried forward, it cannot simply be withdrawn as cash.

Instead, section 11F(3) of the Income Tax Act provides three ways the balance can eventually be used. The route a taxpayer takes can make a significant difference to the amount of tax saved.

Section 11F allows individuals to deduct contributions to pension, provident and retirement annuity funds, subject to certain limits, De la Rey and Robb explained.

Broadly, the annual deduction is limited to 27.5% of the higher of remuneration or taxable income, subject to an annual monetary cap of R350,000.

The 2026 Budget Speech proposed increasing this cap to R430,000, but this has not yet been enacted into law.

Where contributions are disallowed solely because they exceed these limits, they become unused excess contributions.

These amounts are carried forward and treated as contributions in later years until they are used. There is no statutory expiry date or separate lifetime cap.

Importantly, De la Rey and Robb said the balance belongs to the taxpayer rather than a specific retirement fund.

This means that someone with several retirement annuities has a single combined balance.

Taxpayers have three options

De la Rey and Robb explained that South African taxpayers who have accumulated unused excess retirement fund contributions under section 11F(3) have three options available.

The first option is to use the balance as a deduction against taxable income in a later year.

However, current contributions are added to the carried-forward amount, and the normal annual limits still apply.

If new contributions already use the available allowance, they noted that there may be no room to use the older balance.

Where there is room, the deduction can reduce taxable income at the taxpayer’s marginal rate, potentially as high as 45%.

This can make the first route particularly valuable for someone who continues earning a substantial income. The downside is that annual limits can mean a large balance takes several years to use.

The second route, De la Rey and Robb said, is to use the contributions for retirement, death, or a lump-sum withdrawal. This can reduce the lump sum amount subject to the applicable tax table.

However, the maximum potential saving is lower than the 45% available against income or qualifying annuity income.

The biggest trap is using the balance against a lump sum that would otherwise have been tax-free. In this situation, the taxpayer gets no tax savings but still consumes the excess contribution balance.

The third route is to use the balance to exempt qualifying annuity income, including income from a living annuity, they explained.

The savings can again reach 45% if the taxpayer has sufficient other income to place the annuity in the top tax bracket.

However, the benefit is limited to the amount of annuity actually received each year. A large unused balance could therefore take many years to exhaust.

These three options can be summarised as follows, according to De la Rey and Robb.

Option	Provision	Applied against	Likely tax value
One	Section 11F(3) read with section 11F(2)	Taxable income in a later year	Marginal rate, up to 45%; annual cap applies
Two	Paragraph 5 or 6 of the Second Schedule	Retirement, death or withdrawal lump sum	Lump-sum rate, from nil to 36%
Three	Section 10C	Qualifying annuity income, including a living annuity	Marginal rate, up to 45%; limited to annuity paid

The same contribution can have very different tax values

De la Rey and Robb stressed that the three options are not simply a matter of choosing whichever route appears most convenient.

When a taxpayer takes a retirement lump sum, the applicable provisions generally apply the excess contributions to the lump sum first.

Section 10C can then apply to qualifying annuity income, with only the remaining balance carried forward. This makes the timing of retirement and the structure of retirement benefits particularly important.

De la Rey and Robb said the same unused contribution can have very different tax values depending on how it is used.

It could be worth up to 45 cents in the rand when deducted against taxable income or qualifying annuity income. Against a lump sum, the maximum potential benefit is 36 cents in the rand.

If a lump sum is already within the tax-free band, the contribution could provide no tax benefit at all, they added.

The position becomes even more complicated when a taxpayer dies. Unused excess contributions are personal to the member and cannot simply be transferred or bequeathed to a spouse or beneficiary.

De la Rey and Robb explained that a death lump sum may still be reduced by the remaining balance. However, in some situations, the balance falls away.

This happens where beneficiaries elect to use the retirement benefit to provide an annuity, and the deceased’s unused balance cannot be used to shelter the beneficiary’s annuity income.

There can also be estate duty implications. Certain post-1 March 2016 contributions used as a deduction against a death lump sum may be treated as deemed property of the deceased.

This means an unused contribution could, in some circumstances, produce little or no income-tax saving while increasing the estate duty calculation.

Taxpayers should plan before using the balance

De la Rey and Robb said taxpayers should first confirm the unused contribution balance reflected by SARS and reconcile it across all their retirement funds.

The next step is to model how and when the balance should be used. This decision requires the taxpayer to consider several important factors.

This includes their remaining working years, current contributions, marginal tax rate, retirement timing, expected annuity income, previous lump-sum withdrawals, life expectancy, and estate-planning objectives.

The timing of retirement from different funds can also affect how quickly the balance is used and the rate of tax relief obtained.

Using the balance over a taxpayer’s lifetime will often provide greater value, particularly where it can be used against income taxed at a high marginal rate.

However, this does not mean taxpayers should automatically avoid taking a lump sum or maximise annuity withdrawals. Liquidity, investment risk, longevity, and estate planning remain important considerations.

The key message, De la Rey and Robb said, is that excess retirement contributions are not simply a tax credit waiting to be claimed.

They are a valuable tax attribute whose value depends on when, how and against what income it is used.

De la Rey and Robb added that section 11F(3) is better understood as a choice about the rate and timing of tax relief.

For taxpayers with large unused balances, careful planning before retirement or making an irreversible withdrawal could mean the difference between securing substantial tax relief and losing part of that benefit altogether.
