SARS eFiling is South Africa’s online tax submission portal — used by millions of SA individuals and businesses to file tax returns, make payments, and manage their tax accounts. Here’s the practical guide to SA eFiling in 2027, common problems and fixes, and the IT careers powering SARS’s digital systems.
SARS eFiling (efiling.sars.gov.za) is the South African Revenue Service’s online platform for tax filing and management. Launched in 2000 and continuously improved since, eFiling allows SA individuals and businesses to: file personal income tax returns (ITR12), file corporate income tax returns (ITR14), submit VAT returns (VAT201), submit PAYE (Pay As You Earn) employer returns (EMP201 and EMP501), check tax compliance status, request tax clearance certificates, and correspond with SARS about tax assessments.
In 2027, SARS has also rolled out the SARS Online Query System (SOQS) and enhanced the SARS MobiApp — an alternative to eFiling on desktop for simpler SA tax submissions. The eFiling platform processes tens of millions of SA tax submissions annually and is one of SA government’s most successful digital services.
You need an SA Income Tax number before you can register on eFiling. If you’ve never paid tax in SA, you can register as a new taxpayer at a SARS branch or online via the SARS MobiApp. Your employer may have already registered you — check your IRP5 or payslip for your tax reference number.
Navigate to the SARS eFiling website, click “Register,” and choose “Individual” for a personal SA tax registration. You’ll need your SA ID number, tax reference number, contact details, and banking details for potential refunds.
SARS will verify your identity using your SA ID number and date of birth against Home Affairs records. For new eFiling registrations in 2027, SARS may require a selfie verification step or an OTP to your SA registered mobile number. If SARS can’t verify you automatically, you’ll be directed to a branch with your ID book or Smart Card.
Once registered, log in and check that your personal details, banking details, and registered address are correct. If you receive an IRP5 from your employer, it should auto-populate in your eFiling profile during the tax season (usually July–November for individual SA taxpayers).
SARS opens the individual tax season annually — typically July for provisional taxpayers and auto-assessed taxpayers, with a submission deadline in October–November. SARS’s auto-assessment feature pre-populates many SA taxpayers’ returns using employer, bank, and medical aid data. Review it, accept it if correct, or edit and submit if you have additional income, deductions, or expenses to declare.
| Problem | Cause | Fix |
|---|---|---|
| Can’t log in / password reset failing | OTP not received or incorrect registered number | Use “Forgot Password” or visit a SARS branch with your ID |
| Return not auto-populating IRP5 | Employer hasn’t submitted EMP501 yet | Wait for employer submission or capture IRP5 manually from your document |
| “Please call SARS” error | SARS identity verification flag on your profile | Call 0800 00 7277 or book a SARS branch appointment |
| Refund not received after assessment | Banking details incorrect or refund on hold | Verify banking details on eFiling — SARS may need bank confirmation letter |
| eFiling portal down / slow | Peak tax season traffic (July–October) | File early morning or during off-peak hours; try SARS MobiApp |
| Tax compliance certificate not generating | Outstanding returns or balance on account | File all outstanding returns and settle any SA tax balance first |
SARS’s digital systems process millions of transactions annually and represent one of SA’s largest government IT programmes. The technology behind SA’s tax system includes:
| SA Employer | IT Roles Available | Tech Stack |
|---|---|---|
| SARS (direct) | Data analytics, cloud, cybersecurity, dev | AWS, Python, SQL, Salesforce |
| TaxTim, SimplePay | Full-stack dev, data, UX | JavaScript, React, Python |
| SA accounting firms (BDO, KPMG, PwC) | Data analytics, cloud, tech consulting | Power BI, Azure, Python |
| SA payroll software (Sage, Pastel) | Development, QA, cloud, support | .NET, cloud, SQL |
| SA banks (SARS integration) | Open banking, compliance tech, data | Java, Python, AWS, cloud |
The IT angle on SA’s tax system: SARS’s eFiling system is a data engineering problem at national scale — integrating third-party data from every SA employer, bank, medical aid, and retirement fund to pre-assess millions of SA taxpayers’ returns annually. The SA professionals building, maintaining, and improving these systems are cloud engineers, data engineers, cybersecurity analysts, and software developers. SA’s fintech sector — TaxTim, SimplePay, and dozens of SARS-integrated software providers — also employs SA IT professionals building the tools SA businesses use to interact with SARS’s systems.

Every lesson is a live call on MS Teams or Google Meet. You see your lecturer, they see you, and you both share screens, so you're doing the work, not just listening.
