The interim EMP501 reconciliation for 2026

What a South African employer must reconcile and submit in the interim EMP501 window from 21 September to 31 October 2026, and how to prepare.

Half-way through the tax year, SARS asks every employer to stop and check its payroll figures. The interim reconciliation is smaller than the annual one, but it is not optional, and for many employers it is where problems that have been building since March first become visible: an employee without a tax number, a month where the payment never matched the declaration.

The 2026 interim window is open now. This article sets out what it covers, the details SARS insists on, the submission channels and their limits, and how to work through the reconciliation in Achekam before the window closes.

The window and the six months it covers

SARS says the employer interim reconciliation period runs from 21 September to 31 October 2026. During that window employers must reconcile their declarations for 1 March 2026 to 31 August 2026 and submit their EMP501 through eFiling or e@syFile Employer.

More generally, SARS says employers must submit an EMP501 reconciliation with IRP5 and IT3(a) certificates for an interim period of 1 March to 31 August, and an annual period of 1 March to the end of February. SARS adds that the deadline is the date published in the latest Government Gazette, so treat the dates above as the ones announced for this season and watch for any change.

What "reconcile" means in practice is agreeing three sets of numbers for each of the six months:

1. what the payroll actually deducted from employees;
2. what you declared on each month's EMP201;
3. what you actually paid SARS.

Then the certificates for the period must agree with all three. SARS's page on completing and submitting employer declarations explains the interim and annual periods, the certificates that go with them and how corrections are made afterwards.

Every employee needs a valid income tax number

SARS says valid income tax reference numbers for employees are mandatory for EMP501 submissions, and that missing or invalid numbers may delay processing or cause the submission to be rejected. SARS has enforced this strictly since the February 2026 employer filing season.

This is the item most likely to hold you up, because it depends on other people. A new employee who has never registered as a taxpayer, or who gave you a number with a digit wrong, cannot be fixed on the last day of October. Start with a list of every employee paid between March and August and check that each one has a number that looks complete. Chase the gaps now. Accountants and bureaus will find a fuller routine for collecting these details in employee details to collect before tax certificates.

eFiling, e@syFile Employer and the certificate limit

Choose the channel to suit your payroll size. SARS says e@syFile Employer can be used by all employers, while eFiling is limited to a maximum of 50 IRP5/IT3(a) certificates per submission. Employers with 5 or fewer certificates who cannot use either may book a SARS branch appointment.

An employer with more than 50 employees paid in the period should plan on e@syFile Employer rather than discovering the eFiling limit mid-submission.

After you submit, corrections go through the EMP501

Once the reconciliation is in, the route for fixing mistakes changes. SARS says that once an employer has submitted the EMP501, corrections are made through the EMP501 and not the EMP201.

That is a good reason to resolve differences before you submit rather than afterwards. If month four shows a declaration that does not match the payment, find out why and fix it while the EMP201 route is still the right one, and only then file the reconciliation. What SARS charges when an EMP501 is filed late is explained in penalties for a late EMP501 reconciliation.

Reconciling month by month in Achekam

Achekam's EMP501 reconciliation shows, month by month, what was deducted, declared and paid, and what the certificates report. It produces the certificate file that SARS e@syFile Employer imports. That month-by-month view is the three-way check described above, laid out for you; the work is in investigating any month that does not agree.

The certificates themselves are prepared from issued payslips and download as PDFs. A certificate cannot be issued while an employee's ID or tax number is missing. It can still be produced for checking, so you can see the figures, but it will not be issued until the missing detail is filled in. An IRP5 is issued where tax was deducted and an IT3(a) where it was not.

Achekam submits nothing to SARS. A person imports the file into e@syFile Employer, or uses eFiling within its limit, submits the reconciliation and records the reference SARS gave.

A working order for the next few weeks:

1. Open the reconciliation and look for any month where deducted, declared and paid do not agree.
2. Resolve each difference with your accountant before submission.
3. List every certificate that cannot be issued and collect the missing ID or tax numbers.
4. Produce the e@syFile import file once every certificate can be issued.
5. Submit, record SARS's reference, and keep the file with the period's payroll records.

The annual reconciliation follows the same pattern for the full year; the certificates and the year-end process are covered in IRP5, IT3(a) and the EMP501.

Use the interim as a rehearsal

Whatever you fix now is something you will not have to fix in the annual season. Treat the interim reconciliation as the rehearsal for the year-end: clear the missing tax numbers, settle the months that do not agree, and submit well before 31 October 2026, leaving time for SARS to respond if anything is rejected.
