RA deduction limit 2026: What South African taxpayers need to know after the Budget

The 2026 Budget made a significant change to retirement fund tax incentives in South Africa. The maximum retirement annuity (RA) contribution deduction under Section 11F of the Income Tax Act was raised from R350,000 to R430,000 per tax year.

For individuals contributing the maximum to their RAs, this represents an additional R80,000 of deductible contributions — a meaningful difference in tax liability, particularly for those in the 41% or 45% marginal tax brackets.

This guide explains the new limit, how to calculate your maximum deductible amount, and what happens to contributions that exceed the cap.

The Section 11F deduction — how it works

Section 11F of the Income Tax Act 58 of 1962 allows South African taxpayers to deduct contributions made to retirement annuity funds from their taxable income. The deduction applies to contributions to:

Retirement annuity funds (RAs)

Pension funds (employee contributions above the employer's contribution)

Provident funds (employee contributions above the employer's contribution)

The deduction is calculated as the lesser of two amounts:

27.5% of the higher of remuneration or taxable income

R430,000 (the annual cap, updated in Budget 2026)

This means the cap is a ceiling, not a floor. If 27.5% of your income is less than R430,000, the 27.5% figure is your maximum. If 27.5% of your income would exceed R430,000, the R430,000 cap applies.

Calculating your maximum deductible contribution

If your taxable income is below R1,563,636

At this income level, 27.5% of your income is less than R430,000, so the 27.5% rule is the binding constraint.

Example: Taxable income of R800,000

27.5% of R800,000 = R220,000

This is less than R430,000

Maximum deductible RA contribution = R220,000

If your taxable income is R1,563,636 or above

At this income level, 27.5% of your income equals or exceeds R430,000, so the cap is the binding constraint.

Example: Taxable income of R2,000,000

27.5% of R2,000,000 = R550,000

This exceeds R430,000

Maximum deductible RA contribution = R430,000

The change from the 2025 tax year

In the 2025 tax year, the cap was R350,000. This means:

Taxpayers earning above R1,272,727 per year had their deduction capped at R350,000

From the 2026 tax year, the cap rises to R430,000

The breakeven income (where the 27.5% rule and the cap produce the same answer) shifts from R1,272,727 to R1,563,636

What happens to contributions above the deduction limit

Contributions to an RA that exceed the Section 11F deduction limit in a given tax year are not lost. They are carried forward to future tax years and deducted in those years, subject to the applicable annual cap.

This is an important practical point: high-income earners who contribute more than R430,000 per year to their RAs are not penalised — the excess is simply deducted in subsequent years.

The carried-forward amount also has implications on death: contributions that have not been deducted at the time of death are deductible against the deceased's final return, which can significantly reduce the estate's tax liability.

The tax saving — how much does the higher cap matter?

The additional R80,000 of deductible contributions (from R350,000 to R430,000) is worth:

R28,800 in tax saved for a taxpayer in the 36% marginal bracket

R32,800 in tax saved for a taxpayer in the 41% marginal bracket

R36,000 in tax saved for a taxpayer in the 45% marginal bracket

This is the additional tax saving on the increased cap alone — for those who were previously capped at R350,000 and can now deduct R430,000.

The two-pot system and RA contributions

Since September 2024, all retirement fund contributions are allocated to two pots:

Savings pot (one-third of contributions): accessible before retirement, subject to tax at marginal rate and a minimum withdrawal of R2,000

Retirement pot (two-thirds of contributions): locked until retirement, with very limited exceptions

The Section 11F deduction calculation is unchanged by the two-pot system — you still get the deduction on total contributions up to the cap, regardless of how the contributions are split between pots. The tax treatment of withdrawals from each pot is different.

Other key 2026/27 tax figures

The SA Financial Services MCP Server maintains all current SARS figures. Key 2026/27 rates relevant to retirement planning:

Income tax brackets: unchanged from 2025/26 in nominal terms (subject to full Budget announcement)

Primary rebate: R17,820

RA deduction cap: R430,000 (raised from R350,000)

Two-pot savings pot minimum withdrawal: R2,000

Living annuity drawdown range: 2.5% to 17.5% of fund value annually

What high-income earners should do

If you are earning above R1,272,727 per year and were previously contributing exactly R350,000 to your RA — the maximum that was previously deductible — you can now increase your contribution by up to R80,000 without exceeding the deductible cap.

Whether that additional R80,000 should go to an RA or to other investments depends on your full financial picture — your age, existing retirement savings, access to funds, estate planning considerations, and marginal tax rate. This is a question for a licensed financial advisor.

What the tax law says is clear: the new cap is R430,000, and contributions up to that level are deductible.

A note on SARS figures and AI tools

General AI assistants often provide incorrect figures for South African tax thresholds — because they are trained on historical data and do not update automatically when the Budget is announced. The SA Financial Services MCP Server is maintained after every Budget and every statutory triggering event, and returns the `figures_as_at` date with every calculation so you know exactly what year the figures reflect.

Ask any AI assistant what the RA deduction cap is. If it says R350,000, it is using 2025 figures. If it says R430,000, it is either using current data or it has been updated since publication.

Always verify statutory figures from current SARS publications or a tool that documents its data maintenance date.
