EMP501 interim reconciliation: what to check before you file by 31 October

The 2026 interim EMP501 is due by 31 October 2026. SARS opened the window on 21 September, and the return reconciles what you declared and paid for the six months from 1 March to 31 August 2026 against the tax certificates for the same period. SARS warns that a late EMP501 draws a penalty of 1% of your annual PAYE for every month it stays outstanding, up to 10%.

This guide is for the owner or finance lead who runs payroll, or signs off on it, without a payroll department behind them. The dates and rules come from SARS’s notice to employers of 31 August 2026.

What is the EMP501, and how is it different from the EMP201?

The EMP201 is the monthly declaration: by the 7th of each month you declare and pay the PAYE, UIF and Skills Development Levy you withheld or owe for the month before. The EMP501 is the reconciliation that sits on top of those months. Twice a year it checks that three sets of figures agree: what you declared on your EMP201s, what you actually paid SARS, and what your employees’ tax certificates (the IRP5s and IT3(a)s) say they earned and had deducted.

The interim is a half-year check, but it isn’t optional: SARS says all employers must submit it by 31 October “to avoid late-submission penalties”. SARS hadn’t announced the 2027 annual window by early October; the 31 May deadline is set by a standing SARS notice.

What has to match before you submit?

SARS lists three things your interim EMP501 must reflect:

• Reconciled PAYE, UIF and SDL that match the EMP201s you submitted for March to August. The EMP501 comes prepopulated with these; where they differ from the interim certificates your payroll produced, SARS says you must correct the figures.
• The payments you actually made for the period, without any penalties or interest.
• Accurate payroll and employee information: the payroll figures, each employee’s income tax number, and the IRP5 and IT3(a) certificates for 1 March to 31 August 2026.

The point of the exercise is to catch a month you under-declared. If the reconciliation shows you owe more PAYE than you declared, SARS attributes the shortfall to the last month of the period, August, and warns that an incorrect monthly calculation can bring penalties and interest.

Do all my employees need income tax numbers?

Yes, and it is the rule that can stop a submission outright. SARS has strictly enforced income tax numbers in e@syFile Employer and eFiling since the February 2026 filing season, and its notice says missing or invalid numbers “may delay processing and may result in EMP501 submissions being rejected.” Before you start, check every employee on the payroll has a valid number. You can register employees or look up their numbers through the ITREG process on eFiling or e@syFile, or the Tax Reference Number enquiry service on eFiling; employees can also register themselves on the SARS website.

How do I submit the EMP501?

There are two channels, and the size of your payroll decides which you can use:

• e@syFile Employer works for every employer, however many certificates you have. Use the latest build: SARS released version 8.0.2 on 18 September 2026, and moving up from 8.0.1 means uninstalling it and reinstalling from eFiling.
• eFiling takes up to 50 IRP5 and IT3(a) certificates per submission.

An employer with five or fewer certificates who can’t use either can book an appointment at a SARS Service Centre. Whichever route you take, submitting isn’t the last step: SARS asks employers to check the submission’s status and the PAYE dashboard afterwards to confirm it was processed.

What happens if the EMP501 is late?

SARS’s notice sets out three consequences:

• A penalty of 1% of your annual PAYE, rising by 1% for every month the return stays outstanding, up to 10%. On an annual PAYE bill of R600,000 that is R6,000 in the first month and up to R60,000 if it’s left. The interim notice warns of it; SARS’s reconciliation guide describes it as imposed when an employer fails to submit the final EMP501 for the year.
• Lost Employment Tax Incentive. An employer claiming the ETI forfeits unused ETI if it doesn’t submit. A non-compliant tax status holds back the ETI refund, and SARS forfeits it if the employer isn’t compliant by the end of the next reconciliation period.
• A criminal offence for an employer who wilfully or negligently fails to submit EMP201 or EMP501 returns, with a fine or up to two years’ imprisonment on conviction.

A late EMP501 also leaves an outstanding return on your record, which is enough to turn your tax compliance status non-compliant for anyone checking it, a buyer included. The SARS guide covers how the other returns and their penalties fit together.

A checklist for the week before you file

1. Every EMP201 for March to August 2026 is submitted and paid.
2. Every employee on the payroll has a valid income tax number.
3. The PAYE, UIF and SDL on your certificates add up to what your EMP201s declared, month by month, and you know the reason for any difference.
4. Every employee you paid in the period has a certificate, and no certificate number appears twice.
5. You have the latest e@syFile Employer build, or 50 or fewer certificates for eFiling.
6. You know where to check the submission’s status and the PAYE dashboard afterwards.

If you’d rather see the dates laid out for your own year-end, the free compliance calendar lists the interim EMP501 beside your other SARS returns and exports them to your own calendar.

How Komply checks an EMP501 before you file

Komply keeps your SARS returns in one dossier. For an EMP501 it works like this:

1. Add the return. Choose EMP501 and the interim cycle, and Komply fills in the 31 October due date. Listing returns with their due dates is on every plan.
2. Check the totals. If you’ve recorded an EMP201 for each month of the period, Komply fills in their PAYE, UIF and SDL sums for you to check or change; then enter the PAYE, UIF and SDL the EMP501 declares.
3. Add the certificates. Upload or paste the export your payroll writes for e@syFile, or a simple seven-column list. Komply checks the file against its own totals and refuses one it can’t read, rather than storing half of it.
4. Read the score. On Pro and Enterprise the EMP501 gets a readiness score out of 100: the EMP201s against the declaration (20 points), the certificate totals (20), tax numbers (20), whether every employee you paid has a certificate (15), timeliness (10), drift against the prior cycle (10) and the payroll source (5). A certificate that carries PAYE without a valid tax number reads Unfileable, whatever the rest scores, because SARS can refuse it. Duplicate certificates are flagged.
5. Check each certificate. From an e@syFile export, Pro and Enterprise also test every certificate: UIF within its ceiling, SDL consistent with the certificate, and PAYE within a band around SARS’s tables. Each test reads Flagged, Clear or Can’t tell, with the reason, and anything the tests don’t model (a lump sum, a directive) reads Can’t tell rather than clear. The file itself isn’t kept, only the results.

Komply files nothing and has no link to your SARS account: you still submit on e@syFile or eFiling. It doesn’t run your payroll or correct a certificate; it tells you which ones to look at. It doesn’t check tax numbers with SARS, only that each one is there and has ten digits. And for a late interim EMP501 it shows the penalty as a dash, with the reason, rather than a guess, because SARS bases the penalty on your annual PAYE, which an interim return doesn’t yet know.

The EMP501 is one of the SARS returns covered in SARS compliance: the complete tax guide for South African businesses, and the page on Komply’s SARS module lists what each plan includes.

Frequently asked questions

When is the interim EMP501 due in 2026?

By 31 October 2026, which is a Saturday. The submission window opened on 21 September, and the return covers 1 March to 31 August 2026.

What happens if I submit my EMP501 late?

SARS warns of an administrative penalty of 1% of your annual PAYE for each month it is outstanding, up to 10% (its reconciliation guide applies it to a missing final return for the year); an ETI employer forfeits unused ETI; and wilfully or negligently not submitting is a criminal offence.

Can I submit the EMP501 on eFiling?

Yes, for up to 50 IRP5 and IT3(a) certificates per submission. Above that, use e@syFile Employer, which takes any number.

Will SARS reject my EMP501 if an employee has no tax number?

It may. SARS has enforced income tax numbers since the February 2026 filing season and warns that missing or invalid numbers may delay processing or lead to the EMP501 being rejected.
