Auto-Assessment Is Not the Final Answer
This article will count 0.25 units (15 minutes) of unverifiable CPD. Remember to log these units under your membership profile.
You opened eFiling this morning and half your client list already has an auto-assessment sitting there. The numbers look neat. SARS has done the calculation. Refunds are paying out within 72 hours. So what exactly are you doing this filing season?
Plenty. Auto-assessment did not replace the tax practitioner. It changed what the work looks like, and your job now is to make sure your clients understand that too.
The Anxiety Is Real. The Work Is Not Gone.
Every July, the same question lands in practitioner WhatsApp groups. Are we slowly being made redundant? It is a fair question. SARS pulls third-party data from employers, banks, medical schemes, retirement funds, and insurers, then issues an assessment without anyone touching a return. The 2026 dates have not yet been confirmed by SARS, but the structure will repeat. Your clients will get an SMS or email pointing them to eFiling, the SARS MobiApp, WhatsApp on 0800 117 277, or the 1347277# USSD line.
For a salary earner with one IRP5, a medical aid, and nothing on the side, the auto-assessment will mostly be correct. For everyone else, the auto-assessment is a starting point, not the final answer. That is where you still come in, and where the conversation with your client matters most.
What SARS Cannot See, and Why It Matters
The auto-assessment is built from what third parties report. Anything outside that data does not appear. As Auto-Assessment or Auto-Oops? laid out for the 2025 season, the most common gaps are rental income, side-hustle earnings, sole proprietor income, home office expenses, travel claims, crypto disposals, foreign income, RA top-ups paid outside payroll, section 18A donations, and out-of-pocket medical expenses.
If your client just presses "Accept" and one of these applies, the assessment is wrong. Penalties for an understatement can reach 200% of the shortfall, plus interest. SARS will not chase it next week. They will chase it in two or three years, often when the client has forgotten the year even existed. The legal responsibility for the return sits with the taxpayer, not with SARS, even when SARS issued the assessment. This is exactly the point Is My Auto-Assessment Correct? made when auto-assessments first scaled up: SARS calculates, but the taxpayer carries the risk.
This is what you have to make every client understand. The review is not optional. It is the only thing standing between them and a future penalty letter.
What You Should Do This Season
Here is the practical to-do list. None of this is new work invented to fill time. It is the standard tax practitioner workflow, repackaged for an auto-assessment world.
Tag the auto-assessed clients on your list.
Decide who you expect SARS to auto-assess and confirm contact and banking details on eFiling before the season opens. Outdated banking details delay refunds, and the client will blame you.
Wait for the SMS or email.
Do not log in to eFiling before SARS has issued the notification, because the assessment may not be there yet. Once it lands, the client should forward it to you within 48 hours.
Pull the Third-Party Data Certificate.
Log in to eFiling, click the Third-Party Data Certificate search button, and download the data SARS used. This is your audit trail.
Cross-check against source documents.
Compare every IRP5, IT3(b), IT3(c), medical aid certificate, and RA certificate against what SARS captured. If anything is missing or wrong, the institution that supplied the data must correct it and refile with SARS before you submit anything.
Scan for missing income and deductions.
Use a short intake form to ask the client about rental income, freelance work, home office use, travel logbooks, donations, and medical expenses paid out of pocket. Be careful with home office claims: as Home Office Deductions: The CGT Consequences Many Taxpayers Miss explains, the saving today can become a capital gains bill on resale.
File the correction where needed.
If the auto-assessment is incomplete or wrong, submit a full ITR12 on eFiling before the non-provisional deadline. This overrides the auto-assessment with the correct position.
Build the evidence file.
Save the auto-assessment, the third-party data, the client's supporting documents, and your working papers. The recent court reminder in The Case for Reliable, Credible and Authentic Evidence in Resolving Tax Disputes shows what happens when the file is thin. Unsigned acknowledgements and hearsay will not save your client if SARS comes back later.
What You Can Charge For
The mistake many practitioners (and clients) make is bundling the auto-assessment review into the annual fee as a quiet favour. It is not a favour. It is professional tax work, and every step is billable if you structure your engagement that way. Items to itemise on your engagement letter or fee quote:
Assessment review.
Pulling the third-party data, reconciling it against source documents, and producing a short written opinion on whether the auto-assessment is correct, too high, or too low. Quote this as a fixed fee per return.
Missing-income and deduction interview.
A 20 to 30 minute consultation walking the client through rental, side-hustle, home office, travel, donations, foreign income, and crypto questions. Fixed fee or a short hourly block.
Correction filing.
Where the auto-assessment is wrong, preparing and submitting a full ITR12 to override the SARS calculation. Charge this at your standard return-preparation fee.
Third-party data correction follow-up.
Where the data SARS holds is wrong (an IRP5 with an error, a missing medical certificate), the time spent liaising with the issuer to fix the source data and refile with SARS. Billable on time spent.
Banking and contact detail updates on eFiling.
Small but real work, especially where verification SMS or OTP issues delay refunds. Bundle into the review fee or quote as a once-off admin item.
Evidence file build and storage.
Collating the assessment, third-party data, client documents, and your working papers into a defensible audit file. Bundle this into the review fee but name it on the quote so the client sees the value.
Objections and SARS queries later.
If SARS comes back two years later and queries the position, the work to respond is a separate engagement. Make this explicit in your engagement letter so neither side is surprised.
A simple tiered structure works well: a low flat fee for single-IRP5 clients with nothing on the side, a higher flat fee for clients with one or two extra income or deduction streams, and a scope-based quote for the genuinely complex (multiple income sources, foreign income, crypto, provisional taxpayers invited to auto-assessment). The exact rand amounts depend on your market and your client mix. The principle is the same: every step is named, scoped, and priced.
Send your fee schedule out before the season opens, not after the work is done. Clients accept fees they were warned about, and resent fees that appeared on the invoice. The full practitioner-to-client letter, with a tier table and intake form annexure ready to brand, is available as a companion CIBA template.
Where the Real Risk (and Value) Sits
The salary-only client is the easy one. The risk and the value both sit with the rest of your book. The Airbnb host who got an IRP5 from a part-time job. The Uber driver with one car under finance. The freelance graphic designer billing four clients in three currencies. The small retailer who took a small salary and drew the rest. These are the South African informal and gig economy in practice, and SARS sees only a fraction of what they earn or spend. Catch the gap and you save the client a future penalty. Miss it and the client absorbs the cost, the business stalls, and you lose the trust.
The Practical Takeaway
Auto-assessment did not retire you. It moved you from "the person who captures the return" to "the person who validates the assessment and protects the client from a wrong number going final." That is the more valuable role, and it is harder for SARS to automate away.
Tell every client. Build the review into your standard tax service. Itemise the fee. Keep the evidence file. And stop apologising for the work, because what you are protecting is real.
Alert Your Clients
The hardest part is not the technical work. It is getting clients to understand that a "refund within 72 hours" SMS does not mean the job is done. Many will assume the auto-assessment is final, accept it, and move on. Your job is to interrupt that reflex, and to do it before you bill them for the review.
Send it now, by email, with read receipts on. Follow up by WhatsApp for clients who do not reply within a week. Treat the conversation as part of the service, because it is.
