Interim EMP501 Season: Six Weeks, Then Penalties
This article will count 0.25 units (15 minutes) of unverifiable CPD. Remember to log these units under your membership profile.
SARS has written to employers about the interim reconciliation. The window is 21 September to 31 October 2026. Six weeks, and most of your clients will only think about it in week five.
The deadline and what it covers
Employers must reconcile the first six months of the reconciliation year, 1 March 2026 to 31 August 2026, and submit the EMP501 by 31 October 2026 on eFiling or e@syFile Employer. The submission must reflect:
Reconciled PAYE, UIF and SDL matching the EMP201 returns already filed. Where the prepopulated figures differ from the interim IRP5/IT3(a) certificates, you must correct them.
Actual payments made during the period, excluding penalties and interest.
Accurate payroll and employee data, including employee tax reference numbers and the IRP5/IT3(a) certificates for the six-month period.
Employers with fewer than 50 employees may use eFiling. eFiling caps out at 50 IRP5/IT3(a) certificates per submission, so everyone else uses e@syFile. Employers with five or fewer certificates who cannot use either channel can book a SARS branch appointment.
For more information about completing manual certificates, employers can go to the e@syFile™ Employer User Guide or access the Step-by-Step Guide to the Employer Reconciliation Process.
Four changes for 2026
New e@syFile build, planned for release in mid-September 2026. Do not start capturing on the old version.
BRS version 25.3.0 for the 2026-08 interim period is already on the SARS website. Your payroll system must align with it before you submit. We covered the earlier BRS updates for the 2026 tax year when version 24 was issued.
A new ITREG source code aimed at cutting duplicate income tax registrations for employees.
Minor source code validation and description changes. Small, but they are the kind of thing that bounces a submission.
Income tax numbers are required
SARS has strictly enforced income tax numbers in e@syFile and eFiling since the February 2026 employer filing season. Missing or invalid numbers can delay processing or see the EMP501 rejected outright.
Register or retrieve them through ITREG or BundleReg, the Tax Reference Number Enquiry Service on eFiling, or a branch appointment. Employees can also register themselves on the SARS website.
What non-compliance costs
Administrative penalty of 1% of annual PAYE for late submission, rising 1% per month to a maximum of 10%.
ETI forfeiture for employers who fail to submit or who sit with a non-compliant status. Unused ETI is simply lost.
Fine or up to two years imprisonment for wilfully or negligently failing to submit EMP201 or EMP501 returns, for failing to deduct or pay over PAYE, for not delivering IRP5 or IT3(a) certificates on time, or for using deducted employees' tax for anything else.
One detail worth flagging to clients: any shortfall corrected on the EMP501 is attributed to the last month of the reconciliation period. Fix a March error in October and the penalty and interest land on August, not March. Getting the monthly EMP201 right is cheaper than reconciling it later.
Do this in the next two weeks
Run an income tax number audit across every payroll client now, before the window opens. This is the single biggest cause of rejected submissions, and it takes days to resolve, not minutes.
Confirm with each client's payroll provider that they are on BRS 25.3.0.
Diarise the e@syFile download for mid-September rather than the week of the deadline.
After submitting, check the submission status and the PAYE Dashboard. A submitted EMP501 is not a processed EMP501.
The firms that bill well in October are the ones that did the data cleanup in September. As we noted when annual EMP501 season opened in April, SARS is now fixing bad data upstream rather than dealing with the fallout later.
