The EMP501 Reconciliation Explained for South African Employers

How the EMP501 reconciliation works, when the interim and annual runs are due, and why IRP5 certificates come out of the same process on SARS e@syFile.

Updated 2026-07-30

You file an EMP201 every month and think that's the relationship handled. Twice a year, SARS asks a different question: does the whole year actually add up? That question is the EMP501.

What it checks, and when

The EMP501 reconciliation compares two things that should match but don't always: what you declared and paid across your monthly EMP201s, and what your payroll records show you actually paid each employee. A rate applied incorrectly in March or a bonus left out of one payslip can sit quietly for months. The EMP501 is where it surfaces.

There are two of them a year. The interim reconciliation covers March to August and is filed around September and October. The annual reconciliation covers the full tax year, March through February, and is filed around April and May. The interim is a mid-year check-in; the annual is the one that matters most, because it's the reconciliation your employees' tax certificates come out of.

Both are submitted through SARS e@syFile rather than eFiling directly. You import or capture your payroll data for the period, and e@syFile checks it against what was already declared through your EMP201s. Discrepancies show up as errors you have to resolve before you can submit, so a year of small drift becomes a list of things to explain at exactly the point you'd hoped to be finished.

Certificates come out of this, which raises the stakes

The annual EMP501 is also how you generate and issue IRP5 certificates, or IT3(a) certificates for employees who earned below the tax threshold, to your staff. Those certificates are what your employees use to file their own personal tax returns.

That's what turns a reconciliation error from your problem into theirs. Get a figure wrong and it doesn't stay inside your accounting; it lands on someone's tax certificate and follows them into their own return. Add a late or inaccurate submission and you're looking at penalties on top of an awkward conversation with an employee whose IRP5 doesn't match what they remember earning.

The reconciliation is only ever as easy as the twelve EMP201s that fed into it. Accurate monthly filing makes the EMP501 a few hours of checking. Inaccurate filing turns it into a hunt through a year of payslips trying to work out where things drifted, six months after anyone remembers why.

Twice a year is not often, which is exactly why it's easy to under-prepare for. E·BIZI Pay keeps your monthly numbers consistent so the EMP501, when it comes around, is confirmation rather than a surprise.

Common questions

What's the difference between the EMP201 and the EMP501?
The EMP201 is your monthly declaration and payment. The EMP501 is the twice-yearly reconciliation that checks all those monthly EMP201s against what your payroll records actually say you paid your staff.
When is the EMP501 due?
There are two: the interim reconciliation covers March to August and is filed around September and October, and the annual reconciliation covers the full tax year, March to February, filed around April and May.
What is an IRP5 and where does it come from?
It's the tax certificate you issue each employee showing what they earned and what was deducted for the year. You generate IRP5s (or IT3(a) certificates for employees below the tax threshold) as part of the annual EMP501 run.
What happens if my EMP501 doesn't reconcile?
SARS flags the mismatch, and you'll need to explain or correct it before certificates and submissions are accepted as final. Late or inaccurate reconciliations can also bring penalties.
