SARS Tax Season 2026 Launches Next Week: Check Your Banking Details Now or Risk Delayed Refunds
Miss This Step Before Tax Season 2026 and Your Refund Could Be Frozen
The South African Revenue Service (SARS) has issued a direct warning to taxpayers across South Africa: if your banking details or contact information on your SARS profile are outdated or incorrect, you risk serious delays — or outright failure — in receiving your tax refund when Tax Season 2026 officially opens next week. This is not a suggestion. SARS has made it clear that incorrect banking details are one of the primary reasons refunds get stuck, and the window to fix this before the season launches is closing fast.
For business owners, sole proprietors, and individual taxpayers alike, the opening of Tax Season 2026 is a hard deadline you cannot push back. Understanding exactly what SARS needs from you — and making sure your profile reflects it accurately — is the difference between a smooth filing experience and weeks of frustrating back-and-forth with a government revenue authority that is not known for moving quickly.
What SARS Is Warning Taxpayers About Right Now
With Tax Season 2026 set to launch imminently, SARS has urged all taxpayers to log into their eFiling profiles or visit the SARS MobiApp and verify that their banking details and contact information are current and accurate. This is a proactive step SARS wants completed before the season opens — not after you have already submitted your return and are waiting on a refund that never arrives.
The core concern is straightforward: SARS pays refunds directly into the bank account registered on your eFiling profile. If that account is closed, incorrect, or belongs to someone else, the refund cannot be processed. In some cases, funds paid to incorrect accounts create additional administrative and legal complications that take significantly longer to resolve than simply updating your details beforehand.
Contact details matter just as much. SARS uses your registered email address and mobile number to send verification codes, notifications, and correspondence. If those details are out of date, you may miss critical communications — including requests for supporting documents — that can delay your assessment or trigger a compliance flag on your account.
Who Is Affected by This Warning
This warning applies broadly, but certain groups of taxpayers in South Africa face a higher risk of having outdated information on file.
Individuals who have changed banks in the past year — whether by choice or because a bank account was closed — need to update their SARS banking details immediately. The same applies to anyone who has recently switched mobile networks, changed their email address, or moved to a new physical address. If you registered on eFiling several years ago and have not updated your profile since, there is a real chance at least one piece of information on your profile no longer reflects reality.
Small business owners and sole proprietors who file both personal and business tax returns face compounded risk. An outdated detail on either profile can cascade into delayed refunds, missed correspondence about VAT or PAYE submissions, and unnecessary compliance queries. For an SME already managing cash flow tightly, a delayed refund of even a few thousand rand can have a real operational impact.
Provisional taxpayers — those who earn income outside of a standard employment salary, including freelancers, consultants, landlords, and business owners — should treat this warning with particular urgency. Their tax affairs tend to be more complex, and any administrative error at the point of filing creates a longer resolution timeline.
The Real Consequences of Getting This Wrong
A delayed refund is the most obvious consequence of having incorrect banking details, but it is far from the only one. When SARS attempts to pay a refund and it fails due to incorrect account information, your return does not simply get reprocessed automatically. You will need to contact SARS directly, verify your identity, submit proof of your correct banking details, and wait for a manual review — a process that can take weeks or longer depending on SARS's current workload.
Beyond refund delays, outdated contact details create a compliance exposure that many taxpayers do not anticipate. If SARS sends a request for supporting documents or a query about your return to an email address you no longer use, and you do not respond within the required timeframe, SARS can issue an estimated assessment — meaning they calculate what they believe you owe, often without the benefit of your actual figures. Contesting an estimated assessment requires additional effort and time, and interest can accrue on any amount SARS determines is owed during the dispute period.
For businesses that need a Tax Clearance Certificate — required for government tenders, certain contracts, and BEE verification processes — a compliance flag or unresolved return can block issuance of that certificate entirely. A single missed communication from SARS, sent to an old email address, can therefore have consequences that extend well beyond your annual tax return.
How to Update Your SARS Banking Details Before Tax Season 2026 Opens
The process is straightforward, but it must be completed before you submit your return. Here is exactly what to do.
Log into your eFiling account at efiling.sars.gov.za. Navigate to your profile and select the banking details section. Verify that the account number, account type, and bank name are all current and accurate. If anything needs to change, update it now and save the changes. SARS may require you to verify the update through a one-time PIN sent to your registered contact details — which is another reason your mobile number and email address must also be correct before you begin.
If you use the SARS MobiApp, the same verification and update process is available through the app. SARS has actively promoted the MobiApp as a faster and more accessible alternative to desktop eFiling, particularly for individual taxpayers.
Taxpayers who are unable to update their details online — for example, if they have lost access to their registered contact information and cannot receive the verification PIN — will need to visit a SARS branch in person. Bring your original identity document, proof of your new bank account (a recent bank statement or official letter from your bank), and proof of address. Branch visits currently require an appointment booked through the SARS website or contact centre.
If you are not sure whether your current details are correct, the safest action is to log in and check before the season opens. Do not assume your details are still current just because you filed successfully last year — bank account changes, phone number updates, and email migrations happen throughout the year and are easy to forget when tax season is months away.
What South African SMEs Should Do Right Now
For SME owners managing compliance across multiple registrations — income tax, VAT, PAYE, and potentially provisional tax — the start of a new tax season is a natural trigger point to audit your entire SARS profile, not just your banking details.
Start by logging into eFiling and reviewing every registered detail: banking information, email address, mobile number, and physical address. If you have employees, confirm that your PAYE registration details are current and that your employer reconciliation submissions are up to date. If you are VAT-registered, check that your VAT banking details match your income tax banking details — SARS holds these separately, and a mismatch can delay VAT refunds independently of your income tax processing.
Consider designating a specific person in your business — whether that is you, your bookkeeper, or your accountant — as responsible for verifying SARS profile details at the start of each tax season. This is a low-effort task that takes less than fifteen minutes but can prevent weeks of administrative headaches.
If you are uncertain about your overall compliance status — not just your banking details, but your full standing with SARS and other South African regulators — running a compliance check before filing season opens is the smartest move you can make right now. Many SMEs discover outstanding compliance issues only when they urgently need a Tax Clearance Certificate or when SARS raises a query mid-season. Finding out early gives you time to resolve issues before they become blockers.
Check Your Compliance Status Before You File
Tax Season 2026 is not a drill. SARS has issued this warning for a reason — incorrect banking and contact details cause real delays, real compliance flags, and real operational consequences for South African businesses and individuals who cannot afford to wait weeks for a refund or spend hours resolving an administrative error that was preventable.
Update your SARS banking details today. Verify your contact information on eFiling or the SARS MobiApp. And if you want to know exactly where your business stands across all its compliance obligations — not just SARS, but CIPC, UIF, and every other regulator that can affect your ability to operate — run a free compliance check at clearcomply.co.za/check before you file.
