How to Complete Your SARS ITR12 Submission in 2026 | Dyantyi Chartered

Your SARS ITR12 submission for 2026 comes down to five steps done in the right order: gather your IRP5 and supporting certificates, confirm which deadline applies to you, work through the tailored eFiling questionnaire, check every prepopulated figure against your source documents, and submit. Non-provisional taxpayers must file between 13 July and 23 October 2026; provisional taxpayers have until 22 January 2027. Most rejections and delays come from skipping a step, not from the form itself being difficult.

Key facts: ITR12 submission 2026

Non-provisional filing window: 13 July – 23 October 2026 · Provisional taxpayers: until 22 January 2027 · Trusts: 19 September 2026 – 22 January 2027 · Available on eFiling and the SARS MobiApp · Keep supporting documents for 5 years.

What to have ready before you open eFiling

SARS doesn't require you to upload documents with your ITR12, but you need every certificate in front of you to enter accurate figures. Keep all of these for five years. SARS can request them at any point during a verification or audit.

Employment and income

Your IRP5/IT3(a) certificate is the foundation of the return. Every figure you capture must match it exactly, with no rounding and no estimating, because SARS cross-references your return against the IRP5 data it already holds from your employer.

Medical, retirement, and investment certificates

Your medical scheme tax certificate, proof of unreimbursed qualifying medical expenses, your retirement annuity or pension certificate, and your IT3(b) certificate for interest and dividends.

Key SARS ITR12 submission dates for 2026

Auto-assessment notices began going out on 1 July 2026. The dates below differ depending on your taxpayer status. Filing early gives you more time to resolve any queries SARS raises.

Non-provisional taxpayers

The general filing window opened on 13 July 2026 and closes on 23 October 2026. If you're a salaried employee with a single employer and no rental, business, or investment income beyond your IRP5, this is almost certainly you.

Provisional taxpayers and trusts

If you earn freelance income, rental income, or investment returns above the exempt threshold, your extended deadline is 22 January 2027. Trusts file between 19 September 2026 and 22 January 2027. The extended deadline exists because these income structures take longer to reconcile, not as an invitation to leave it until the last week.

How to complete your SARS ITR12 submission on eFiling

eFiling follows a logical sequence once you know where to look. The SARS MobiApp follows an identical flow if you'd rather work from your phone.

Logging in and requesting your return

Log into eFiling and navigate to Returns → Returns Issued → Personal Income Tax (ITR12). Select the 2026 year of assessment. If it hasn't been auto-issued, click "Request Return." The form opens as a guided wizard. Your answers to its initial questions determine which sections appear, so work through them carefully.

Once the tailored form loads, check every prepopulated field against your source documents before accepting the figures. SARS loads data from employers, medical schemes, and investment platforms, but prepopulation doesn't guarantee accuracy, and you're responsible for the return regardless of where the figures came from.

Completing and submitting

Fill in every section that applies to you, using "Save Return" regularly. Run the built-in validation check before submitting. It flags missing or conflicting fields. Once validation passes, click "Submit Return to SARS" and confirm. Your submission isn't complete until you see the confirmation screen and receive a reference number. Save it.

Filing via the SARS MobiApp

Download the SARS eFiling app and log in with your existing credentials. Tap Returns, select Income Tax (ITR12), and request or open your 2026 return. Complete it the same way as on eFiling, review every figure, tap Submit, confirm the declaration, and save your confirmation. It's well-suited to simpler returns with a single IRP5.

What changed on the ITR12 form for 2026

If you're assuming the form works exactly as it did last year, a few updates are worth reading carefully, since ignoring them is a direct route to a SARS query.

Medical scheme selection and prepopulated trust data

SARS has replaced free-text entry for medical scheme names with a drop-down list of approved, licensed scheme names. Select yours exactly as it appears. Typing anything, or picking the wrong one, means your medical deduction won't link correctly. The 2026 form also prepopulates more trust distribution data from IT3(t) certificates; verify these against your own trust statements rather than accepting them at face value.

Retirement fund transfers and residency logic

From the 2026 year of assessment, SARS will reject a return declaring a lump sum linked to a retirement fund transfer if the Recognition of Transfer (ROT) hasn't yet been received from the receiving fund.

If you transferred retirement savings during the year, confirm with the receiving fund administrator that the ROT has been submitted before you file. The investment section also now requires certain items declared at a transactional level per institution, and the residency status questions have been updated, so answer them precisely, since the wrong selection changes which sections display.

Don't face SARS alone. Dyantyi Chartered handles your ITR12 submission, document review, and SARS correspondence, from R850, with no hidden fees.
