Every year, millions of South African taxpayers are owed a refund by SARS — and many do not claim everything they are entitled to. A tax refund calculator, combined with the right deductions and a correctly filed ITR12, can put thousands of rands back in your pocket. Here is exactly how it works.
What Is a SARS Tax Refund and Who Qualifies?
A SARS tax refund occurs when the total PAYE tax deducted from your salary throughout the year exceeds your actual tax liability after all legitimate deductions are applied. Your employer calculates your monthly PAYE based on your salary alone, without considering the medical aid costs, retirement annuity contributions, travel expenses, or home office deductions you may be entitled to claim.
When you file your annual ITR12 tax return and include all eligible deductions, your actual taxable income drops. If the tax on that lower amount is less than what was withheld from your salary, SARS owes you the difference. This is your refund — and it can be substantial, particularly for taxpayers with significant medical expenses or retirement annuity contributions.
Not every taxpayer will receive a refund. If you have additional income sources beyond your salary — such as rental income, freelance work, or investment returns — these may push your actual liability above what was withheld, resulting in an amount owing to SARS rather than a refund. A tax refund calculator lets you estimate your position before filing.

How Is Your SARS Refund Calculated?
Your SARS tax refund is the difference between two figures: the total PAYE deducted from your salary during the tax year, and your actual tax liability after applying all eligible deductions and rebates. The formula is straightforward, but the inputs — particularly the deductions — require careful attention to maximise your outcome.
Tax Refund = Total PAYE Paid − Actual Tax Liability
Actual Tax Liability = Tax on (Gross Income − All Eligible Deductions) − Tax Rebates
The larger your eligible deductions, the lower your actual liability — and the bigger your refund.
Your gross income includes all salary, bonuses, allowances, and any other taxable income you received during the year. From this, you subtract eligible deductions to arrive at taxable income. SARS then applies the appropriate tax bracket rates, subtracts your age-based primary rebate, and arrives at your actual tax liability. The difference between this and what was withheld through PAYE is your refund or shortfall.
One important point many taxpayers miss: tax rebates are not the same as tax deductions. Deductions reduce your taxable income before tax is calculated. Rebates are subtracted directly from the tax amount after calculation. The primary rebate for the 2025/2026 tax year is R17,235 for individuals under 65, R9,444 additional for those 65–74, and R3,145 further additional for those 75 and older.
Deductions That Increase Your SARS Refund
The single most effective way to increase your SARS refund is to claim every deduction you are legally entitled to. Many South African taxpayers leave significant money on the table each year by missing legitimate deductions on their ITR12. Here are the most impactful ones.
- Retirement Annuity (RA) Contributions — Up to 27.5% of your taxable income, capped at R350,000 per year. One of the most powerful tax deductions available. Every rand contributed reduces your taxable income directly.
- Medical Aid Contributions — Medical scheme fees credit applies: R364/month for the main member, R364 for the first dependant, R246 for each additional dependant (2025/26 rates). Directly reduces your tax liability rand for rand.
- Out-of-Pocket Medical Expenses — Qualifying medical expenses paid from your own pocket that exceed 7.5% of your taxable income (if under 65) can be claimed. Keep all medical receipts throughout the year.
- Travel Allowance with Logbook — If your employer pays a travel allowance, you can claim actual business travel costs using a detailed logbook. The logbook must record every trip — date, odometer readings, destination, and business purpose.
- Home Office Expenses — If you work from home regularly and have a dedicated workspace, a portion of rent, electricity, and internet costs may be deductible. SARS requires the space to be used exclusively for work.
- Donations to Approved PBOs — Donations to organisations with Section 18A approval are deductible up to 10% of taxable income. Keep the Section 18A receipt from the organisation.
“A retirement annuity contribution of R2,500 per month can reduce your taxable income by R30,000 per year — potentially adding thousands to your SARS refund.”
TaxPlanners.co.za · Tax Guide 2026How to Check Your SARS Refund on eFiling — Step by Step
Once you have submitted your ITR12, SARS will process your return and issue a Notice of Assessment (ITA34). This is the document that tells you definitively whether you are owed a refund and how much. Here is exactly how to find it and what to look for.
Log Into eFiling
Go to sarsefiling.co.za or open the SARS MobiApp. Log in with your username and password. If you have two-factor authentication enabled, complete that step.
Find Your ITA34
Click on SARS Correspondence → Request Historic IT Notices → Select the tax year → Request. Your ITA34 will appear as a downloadable document.
Read the ITA34
On the first page, look for the assessment amount. A minus sign (−) means SARS owes you money. A positive number means you owe SARS. Also check: Audit: Yes or No.
Check the ITSA
For the exact refund date, check your Income Tax Statement of Account (ITSA) on eFiling. The date next to “Electronic refund” shows when money will reach your bank account.
Verify Banking Details
Go to Maintain SARS Registered Details and confirm your bank account is correct and verified. Incorrect banking details are the most common refund delay. Update if needed.
Wait for Payment
If Audit: No and banking details are correct, your refund arrives within 72 hours of the ITA34. If Audit: Yes, upload requested documents and wait 21 business days after submission.
A minus sign (−) in front of the amount on your ITA34 means SARS owes you that amount. For example, if your ITA34 shows −R8,450, SARS will pay R8,450 into your bank account. A positive amount with no minus sign means you owe SARS. Many taxpayers are confused by this — the minus sign is good news.
Why Is My SARS Refund Delayed? — 6 Common Reasons
SARS processes most straightforward refunds within 72 hours. When refunds take longer, it is almost always due to one of a small set of identifiable issues. Understanding these in advance allows you to resolve them proactively rather than waiting and wondering.
| Reason | What Happens | How to Fix |
|---|---|---|
| Incorrect banking details | SARS cannot process payment — up to 21 business days delay | Update on eFiling → Maintain SARS Registered Details |
| Selected for audit | ITA34 shows Audit: Yes — SARS requests supporting documents | Upload all requested docs via eFiling promptly |
| Outstanding tax returns | SARS withholds refund until all prior years are filed | File all outstanding ITR12 returns on eFiling |
| Existing tax debt | SARS offsets your refund against outstanding amounts owed | Check ITSA for any outstanding balances and resolve |
| Refund under R100 | SARS rolls small amounts to next tax year automatically | No action — carried forward to next year |
| Banking verification needed | New banking details require SARS verification | Submit proof of banking details — takes up to 21 days |
SARS Scam Warning — Refund Season

SARS Auto-Assessment 2026 — Should You Accept It?
Each filing season, SARS issues auto-assessments to taxpayers with straightforward tax affairs — using data gathered from employers, medical aids, retirement fund administrators, and banks to calculate your liability automatically. If your ITA34 shows a refund and you agree with the figures, you can simply log in and accept the assessment without filing a full return.
However, auto-assessments are only as accurate as the data SARS received from third parties. If you have deductions that SARS’s data sources do not capture — such as out-of-pocket medical expenses, a travel logbook, home office costs, or additional retirement annuity contributions paid privately — the auto-assessment will not include them. Accepting an auto-assessment that misses significant deductions means you leave money behind that you were entitled to claim.
The process is straightforward: log into eFiling or the MobiApp, review the pre-populated figures carefully, compare them against your actual IRP5, medical certificates, and RA tax certificate. If everything matches and you have no additional deductions to claim, accept. If you have deductions to add, file your own ITR12 return instead — you can do this even if you have been auto-assessed, up to the filing deadline.
Accepting an incorrect auto-assessment is not a defence against penalties. If SARS later audits you and discovers undeclared income, or if the auto-assessment missed income you should have reported, you remain responsible. Always review the figures before accepting — it takes five minutes and could save you from an unexpected assessment later.
When Will SARS Pay My Refund in 2026?
SARS refund timing depends on two factors: whether your return is selected for audit, and whether your banking details are correct and verified. For straightforward returns with no audit flag and verified banking details, the timeline is fast.
| Scenario | Expected Timeline |
|---|---|
| Audit: No + banking details correct | Within 72 hours of ITA34 being issued |
| Audit: Yes + documents submitted | 21 business days after full document submission |
| Complex multi-year audit | Up to 90 business days |
| Banking details need verification | Up to 21 business days after proof submitted |
| After audit — Letter of Completion issued | Within 7 business days of Letter of Completion |
| Refund under R100 | Rolled over to next tax year automatically |
Filing season 2026 is expected to open in July 2026 for most individual taxpayers. The sooner you file after filing season opens, the sooner your refund arrives — SARS processes returns on a rolling basis, and early filers typically experience faster processing times than those who submit close to the deadline.
