WPS & SIF Files Explained: Mainland vs Free Zone Payroll in the UAE

A practical explainer for payroll, HR, finance, and PRO teams.

If your payroll calendar still assumes a 15-day window to get salaries out, it is now out of date. As of 1 June 2026, Ministerial Resolution No. 340 of 2026 replaced the old rule and set a single, non-negotiable salary deadline: wages for the previous month must clear through the Wage Protection System by the 1st of the following Gregorian month. Combined with the fully digital WPS platform launched in December 2025, salary payments are now monitored in real time, and late payment triggers an automated escalation that starts on day two.

For payroll and finance teams, that raises the stakes on two things you have to get right every month: paying on time, and filing a clean SIF. This guide explains what the WPS is, what a SIF actually contains, who files federally versus through a free-zone authority, the monthly timeline, the common reasons files get rejected, and the penalties for getting it wrong.

Informational only — not legal advice. This article summarises general principles as currently published, based on MOHRE guidance and Ministerial Resolution No. 340 of 2026. Rules, thresholds, and penalty figures are set by MOHRE and change over time, and free-zone rules differ. Verify your specific obligations with MOHRE or your free-zone authority, and take professional advice where needed.

What the Wage Protection System is, and why it exists

The Wage Protection System (WPS) is the UAE's mandatory electronic salary-transfer framework. It was launched in 2009 under Ministerial Decree No. 788 as a joint initiative between the Ministry of Human Resources and Emiratisation (MOHRE) and the Central Bank of the UAE. The purpose is straightforward: to make sure employees are paid in full and on time, and to give MOHRE a live record of who was paid, how much, and when.

Under the WPS, salaries must move through banks, exchange houses, or financial institutions authorised by the Central Bank — never in cash, even with the employee's written consent. The system now covers the overwhelming majority of private-sector workers in the country.

In December 2025, MOHRE, the Central Bank, and Al Etihad Payments rolled out a fully upgraded WPS platform. The significant change was the move from batch processing to real-time digital monitoring: salary data is now verified against the registered employment contract as it is submitted, so a mismatch between the SIF and the contract on file can raise a compliance flag before payment is even released.

What a SIF actually contains

The Salary Information File (SIF) is the structured data file you submit to your WPS agent (the bank or exchange house) each pay cycle. It is not a spreadsheet or a PDF — it is a fixed-format .sif file with strict naming and content rules, and the bank passes its data to MOHRE. A SIF has two record types:

• Employee Detail Records (EDR) — one line per employee, containing the employee's labour card / MOL identifier, the agent routing code, the bank account (IBAN), the pay-period start and end dates, the number of days in the period, the fixed salary component, any variable component, and days of unpaid leave with the relevant code.
• A Salary Control Record (SCR) — one header per file, containing the employer's Establishment ID, the agent code, the file creation date and time, the salary month, the total salary amount, the total record count, and the currency.

The single most common structural error is a mismatch between the SCR header totals and the sum of the EDRs. Every employee must appear in the file — including anyone not being paid that cycle, who must be listed with the correct NOPAY reason code rather than simply omitted. Lawful deductions need the correct deduction code so the system reads the lower net figure as intended rather than as an underpayment.

Who files federally, and who files through a free zone

Here is the point that trips up the most companies: the dividing line is not simply "mainland versus free zone." What determines your obligation is whether your entity is registered with MOHRE and your employees hold MOHRE-issued labour cards.

• Mainland companies registered with MOHRE file the federal SIF through a Central Bank-approved WPS agent, and Resolution No. 340 of 2026 applies in full.
• Most free zones — including DMCC, JAFZA, DAFZA, IFZA, RAKEZ, Dubai South, and the TECOM districts — issue MOHRE labour cards to their employees. These companies register for and file the same federal WPS/SIF as mainland companies. JAFZA in particular is fully integrated with the federal WPS.
• DIFC and ADGM are the genuine exceptions. These financial free zones operate their own independent employment frameworks (DIFC Employment Law No. 2 of 2019; ADGM Employment Regulations 2019), sit outside MOHRE's scope, and do not file the federal MOHRE SIF. They run their own salary-protection and end-of-service arrangements instead.

So the accurate version of the "free zones are exempt" belief is narrow: only entities operating entirely under an independent authority such as DIFC or ADGM are outside the federal SIF. If your staff carry MOHRE labour cards, you almost certainly file the federal SIF regardless of your free-zone address. When in doubt, confirm with both your free-zone authority and MOHRE before your first pay cycle — assuming exemption is a common and costly mistake.

The monthly timeline and the new payment deadline

Resolution No. 340 of 2026 changed the deadline itself. Under the previous regime (Resolution No. 598 of 2022), due dates followed the individual employment contract and employers had a 15-day grace period before enforcement began. Both of those are gone.

The rule now:

• Salaries for the preceding Gregorian month must clear through WPS by the 1st of the following month. Any payment after the 1st is treated as delayed.
• The deadline is fixed regardless of weekends or public holidays — there is no business-day extension.
• An establishment is treated as compliant if it transfers at least 85% of total wages due by the deadline (raised from the old 80% threshold). The remaining portion must be explained by lawful deductions under Article 25 of Federal Decree-Law No. 33 of 2021 — it is not employer discretion, and employees remain entitled to everything they are owed.
• The former 30-day exemption for new joiners has been removed. A new hire's salary must be processed in the cycle they join, even if they start on the 30th.

Because banks typically need one to two working days to process and confirm transfers, the practical consequence is that your SIF should be funded and submitted by around the 29th or 30th, not on the 1st. Working backwards, that means a payroll data cut-off around the 20th to 22nd of the month, giving your team time to finalise attendance, approved leave, overtime, and any variable pay, run and approve payroll, and generate and validate the SIF before submission.

One more point that survives any delegation arrangement: you can appoint a third party to process payroll, but under Resolution 340 the legal responsibility for on-time payment stays with the employer. A provider's late file is still your violation.

Common SIF rejection reasons

Most rejected files fail on formatting and data, not intent. The usual culprits:

• Header-versus-detail mismatch — the SCR total does not equal the sum of the EDR amounts, or the record count is off.
• Identifier errors — an expired or wrong labour card / Establishment ID, or a UID that does not match the contract on MOHRE's file.
• Bank data errors — an incorrect IBAN, account number, or agent routing code, which bounces the transfer.
• Format errors — wrong date or timestamp format, or an incorrectly named file.
• Salary mismatches — a figure below the registered contract salary, or an Emirati paid below the AED 6,000 minimum wage that applies from 2026, which the system now cross-checks in real time.
• Missing records — an employee left out entirely, a new joiner omitted, or an unpaid employee filed without a NOPAY code.
• Threshold breach — a net transfer below 85% of entitled wages without a valid deduction code behind it.

Since the December 2025 upgrade, many of these are flagged at submission rather than discovered days later, which is better for catching mistakes but leaves no room for a file built by hand at the last minute.

Penalties for late or non-payment

Under Resolution No. 340 of 2026, enforcement is automated and phased from the day after the deadline. The escalation reported from the Resolution's annex runs roughly as follows:

• Day 2 — MOHRE notifications and warnings begin.
• Day 5 — new work permit applications for the establishment are frozen.
• Day 11 — administrative fines apply, and the establishment can be reclassified to the Third Category (the lowest tier, which raises MOHRE service fees and restricts activity).
• Day 16 — MOHRE may register a labour dispute on employees' behalf. Higher-risk sectors — construction, transport and storage, security, cleaning, recruitment agencies, and domestic-worker recruitment offices — face accelerated triggers here.
• Day 21 — asset attachment and referral to Public Prosecution for continued non-payment.

Fine amounts are set in the Resolution's annex and MOHRE guidance; filing false information in a SIF has been reported at around AED 1,000 per employee, and serious or repeated violations can reach substantially higher figures alongside criminal referral. Because the escalation is automatic, a company will often be flagged before its own finance team notices the miss — and a red status is now visible to banks, partners, and prospective hires who check an establishment's standing.

The categories excluded from violation calculations include employees in court wage disputes, those reported for absconding, workers under judicial restriction, employees on documented unpaid leave, and certain short-term-permit and specified-sector cases.

Your monthly WPS checklist

Run this as a fixed closing routine every cycle:

1. Confirm your Establishment Card is active and not expiring within the next 60 days, and that your WPS agent service agreement is current.
2. Lock the payroll data cut-off by the 20th–22nd — attendance, approved leave, overtime, and variable pay all finalised.
3. Reconcile joiners and leavers against the MOHRE labour-card register before running payroll, including any new hire who must be paid this cycle.
4. Verify bank details — IBANs and any wage-card updates — before the file is built.
5. Generate the SIF from your payroll system, not by hand, and review the header-versus-detail totals.
6. Check every employee is included, with NOPAY and deduction codes applied where needed.
7. Confirm the 85% threshold is met for each employee on lawful grounds, and that Emirati salaries meet the AED 6,000 minimum.
8. Fund and submit by the 29th–30th so the transfer clears by the 1st, allowing for the bank's processing time.
9. Capture the agent confirmation and bank advice for the cycle and archive them with the SIF.
10. Check your MOHRE compliance status after submission and resolve any flag immediately.

Most WPS failures are not cash-flow problems — they are data problems: attendance in one place, contracts in another, the SIF stitched together from a spreadsheet on the 30th. When joiners, leavers, salary changes, attendance, and the SIF all run from one connected payroll system, the file validates itself before it leaves the building, and the 1st stops being a monthly cliff edge.
