Our free RA tax refund calculator will help you get an idea of how much you can get back from SARS if you contribute to a retirement annuity. The tax return can then be used however you like, but the calculator’s focus is to give you an idea of how much you can get back so you can redirect the returns to your TFSA.

Calculate Your RA Tax Refund from SARS
If you contribute to a Retirement Annuity (RA), you’re eligible for a tax deduction that could put thousands of rands back in your pocket. This is money you can then redirect to your Tax-Free Savings Account (TFSA) for tax-free growth.
The problem is that most people don’t know how to calculate it. They guess, estimate, and hope SARS gives them a refund without understanding how much they’ll actually get back.
This RA tax refund calculator changes that. Enter your gross income, your age, and your planned RA contribution. Whether you earn R25,000 or R2 million per year, this tool shows you a practical estimate of how RA contributions can affect your tax.

How the RA Tax Refund Calculator Works
The calculator uses real 2025/2026 SARS tax brackets, rebates, and the latest R430,000 annual contribution limit (updated March 2026) to show your potential refund.
Here’s what happens when you enter your information:
Step 1: Enter Your Annual Gross Income
This is what you earn before tax. The calculator uses this to determine which tax bracket you fall into (18%, 26%, 31%, 36%, 39%, 41%, or 45%).
Example: If you earn R500,000 gross annually, you fall into the 36% tax bracket.
Step 2: Select Your Age
Your age affects your primary rebate:
- Under 65: R17,235 primary rebate
- 65 to 74: R17,235 + R9,444 secondary rebate
- 75+: R17,235 + R9,444 + R3,145 tertiary rebate
These rebates reduce your total tax bill, so age matters.
Step 3: Enter Your RA Contribution Amount
This is the amount you plan to contribute to your Retirement Annuity during the tax year. The calculator shows the maximum you can contribute (27.5% of income or R430,000, whichever is lower).
Example: If you earn R500,000, you can contribute up to R137,500 (27.5% of R500,000).
Step 4: Hit Calculate
The calculator then:
- Calculates your tax without RA: What you’d owe SARS if you didn’t contribute anything
- Calculates your tax with RA: What you’d owe SARS after deducting your RA contribution
- Finds the difference: Your SARS refund
It also shows:
- Your marginal tax rate (the percentage you pay on your last rand of income)
- Your taxable income (after RA deduction)
- How much SARS is effectively funding your RA (as a percentage)
Understanding Your Marginal Tax Rate
Your marginal tax rate is crucial to understanding your refund. It’s the tax rate applied to your highest income.
South Africa uses a progressive tax system, meaning you don’t pay the same rate on all your income. You pay different rates on different “brackets” of your income.
The 2025/2026 Tax Brackets
| Taxable Income | Tax Rate |
|---|---|
| R1 – R237,100 | 18% |
| R237,101 – R370,500 | 26% (plus base tax of R42,678) |
| R370,501 – R512,800 | 31% (plus base tax of R77,362) |
| R512,801 – R673,000 | 36% (plus base tax of R121,475) |
| R673,001 – R857,900 | 39% (plus base tax of R179,147) |
| R857,901 – R1,817,000 | 41% (plus base tax of R251,258) |
| R1,817,001+ | 45% (plus base tax of R644,489) |
Budget 2026: The R430,000 Cap Increase
In February 2026, the Minister of Finance, Enoch Godongwana, announced a significant change: the annual RA contribution limit increased from R350,000 to R430,000, effective March 1, 2026.
This is the first increase since the cap was introduced in 2016.
What This Means
If you’re a higher earner or self-employed, you now have R80,000 more room to make tax-deductible retirement contributions each year.
Example: High earner (R2 million gross)
- Under old rules: Could contribute max R350,000
- Under new rules: Can contribute max R430,000
- Extra deductible room: R80,000
- Extra tax refund at 41% bracket: R32,800
What If You Exceed the Limit?
If you contribute R200,000 but only qualify for a R150,000 deduction, the extra R50,000 rolls over to next year and can be deducted then.
However, you can’t claim the deduction in the current year. You claim it in the following year when you file your tax return.
Why Your Refund Matters
When you get a tax refund from your RA contribution, you have a choice:
- Spend it (new car, holiday, kitchen)
- Save it (fixed-term savings account)
- Invest it in your TFSA (so SARS can’t touch it)
RA Refund → TFSA
If you decide to invest it in your TFSA, here’s how it’ll work:
- Contribute to RA → Reduces your taxable income
- Get SARS refund → Money from the government
- Deposit refund to TFSA → Tax-free growth forever
Example
You earn R500,000/year (36% tax bracket)
- Contribute R137,500 to RA
- Estimated tax savings: R137,500 × 36% = R49,500
- You can deposit R46,000 into your TFSA (then you’re left with an extra R3,500)
- This R46,000 grows tax-free for life
- No capital gains tax, no dividend tax, no income tax on withdrawals
RA and TFSA products work differently:
- An RA offers tax deductibility on contributions, but withdrawals are subject to retirement rules and tax treatment
- A TFSA does not give an upfront deduction, but growth and withdrawals are tax-free within the contribution limits
The RA tax refund calculator does not tell you which one to choose. It helps you see the numbers more clearly so you can make a more informed decision

RA Tax Refund Calculator
Last updated 5 April 2026Our free RA tax refund calculator will help you get an idea of how much you can get back from SARS if you contribute to a retirement annuity. The tax return can then be used however you like, but the calculator’s focus is to give you an idea of how much
How the RA Tax Deduction Works: The 27.5% Rule Explained
Under Section 11F of the Income Tax Act, contributions to an approved retirement fund — including RAs, pension funds, and provident funds — are deductible up to 27.5% of the greater of your taxable income or remuneration, with an annual maximum of R350 000. This deduction reduces your taxable income before PAYE is calculated. If you contribute to a personal RA independently, you claim the deduction when you file your annual tax return and SARS will refund the overpaid tax.
How to Calculate Your RA Tax Saving
The tax saving depends on your marginal tax rate — the rate at which your next rand of income is taxed. For most working South Africans earning R500 000 to R1 000 000, the marginal rate is 36% or 39%. To estimate your annual saving: multiply your total RA contribution by your marginal rate. For example: R100 000 contribution x 36% marginal rate = R36 000 annual tax saving. This is money SARS would otherwise have collected — instead it stays invested and compounding in your RA.
What Is a SARS Tax Refund and When Do You Get It?
A SARS tax refund occurs when you have paid more PAYE during the year than your final tax assessment requires. When you submit your annual ITR12 return, SARS calculates your total tax liability, deducts your RA contributions, and compares this to PAYE already paid. If you overpaid — common for salaried employees making personal RA contributions — SARS issues a refund. Refunds are typically processed within a few weeks of assessment if your affairs are straightforward.
Rollover of Excess RA Contributions
If your total retirement fund contributions exceed the 27.5% deduction limit in a given year, the excess carries forward to future tax years. Importantly, undeducted contributions can significantly reduce the tax due on your retirement lump sum — since those contributions were already taxed before entering the fund, SARS does not tax them again at exit. This makes it advantageous to make additional contributions even above the annual limit in high-income years.
Who Benefits Most from the RA Tax Deduction?
The higher your marginal tax rate, the more valuable the RA deduction becomes. A person in the 18% bracket saves R18 for every R100 contributed. A person in the 45% top bracket saves R45 per R100 — effectively getting retirement savings at a nearly 50% discount. Self-employed people and independent contractors who lack access to employer pension funds benefit especially from RAs, which serve as both their primary retirement vehicle and main source of tax relief.
