The SZV Employer Portal: How to Declare ZV & OV Premiums Online

Every Sint Maarten employer has to deal with SZV — the agency that administers social and health insurance — and the modern way to do that is through the SZV employer portal. According to SZV, the portal lets employers declare their ZV and OV premiums each month, review every premium they have declared online, view their assessments, and file employee mutations such as joiners and leavers. This walkthrough takes you through the monthly declaration cycle step by step, shows you what to prepare before you log in, and flags the mistakes that most often trip employers up. Please treat the figures and the exact on-screen flow as a guide and confirm the current process and figures with SZV directly.

What the SZV portal actually does

The employer portal is SZV's online channel for the routine work of being an employer. SZV states that through the portal you can declare your ZV and OV premiums on a monthly basis, see all of the premiums you have declared online in one place, view your assessments, and submit employee mutations. That last point matters: the portal is not only for money, it is also where you keep SZV's record of your workforce accurate. For the official scope and answers to specific questions, SZV maintains an Employer Portal FAQ, and general obligations are set out on the SZV Employers pages. We recommend reading those alongside this guide, because SZV can adjust the interface and the process from time to time.

What you'll need before you log in

The declaration goes far more smoothly when everything is assembled first. Before you open the portal, have this checklist ready:

• Your SZV employer number and portal login credentials, kept secure and up to date.
• The finalised gross wages for each employee for the declaration month, matching the figures on each loonstrook (payslip).
• A current, correct list of everyone on your payroll for the month, including anyone who joined or left.
• The applicable premium percentages and wage ceilings for the year, since these change on 1 January.
• Your prior month's assessment, so you can reconcile and catch any carried-over difference.
• The submission deadline for the month, noted in advance so nothing slips.

Because the premium rates and ceilings are set annually, always verify the numbers you are applying. The SZV Wage Limits & Premiums page publishes the current figures; confirm them there before you calculate.

The monthly declaration cycle, step by step

The exact button labels and screen names inside the portal are SZV's own, so follow the on-screen flow rather than any fixed wording. The sequence below reflects the general order of the monthly cycle:

1. Finish your payroll run for the month and lock the gross wages, so the numbers you declare match the payslips you issued.
2. Log in to the SZV employer portal with your employer credentials and open the section for a new monthly declaration.
3. Confirm your employee list for the month is complete and correct, applying any joiners or leavers as mutations before you declare (see below).
4. Enter or review the wage figures the portal uses to calculate ZV and OV premiums, checking each employee's base against your payroll records.
5. Apply the current-year premium percentages and wage ceilings, and let the portal calculate the amounts due; sanity-check the total against your own expectation.
6. Submit the declaration before the monthly deadline and save or download the confirmation for your records.
7. Arrange payment of the amount due through the method SZV specifies, and keep proof of payment with the declaration.
8. When SZV issues the assessment, open it in the portal, reconcile it against what you declared, and resolve any discrepancy promptly.

Running this same sequence every month builds a clean, defensible record. If the portal's layout differs from what you expect, the SZV Employer Portal FAQ is the authoritative reference for each screen.

Filing employee mutations: joiners and leavers

A mutation is simply a change to your workforce that SZV needs to know about. The portal is where you record them, and keeping them current is what makes your monthly premium figures correct. Two events come up most often:

• Joiners — when you hire someone, register them as a new employee so their wages are included in the declaration and their insurance record starts on the right date.
• Leavers — when someone's employment ends, record the departure so you stop declaring premiums for them from the correct date and their record is closed cleanly.

File mutations before you finalise the monthly declaration, not after. A joiner missed in the portal means an understated premium and a correction later; a leaver left on the books means you keep declaring for a person who is no longer employed. Both create the kind of mismatch that shows up when SZV reconciles your account. Registration of the business itself as an employer is a separate, one-time step; our guide to registering as an employer in Sint Maarten covers that starting point.

ZV and OV in context: the wider premium picture

The portal centres on ZV and OV, but these premiums sit inside a broader social insurance system. ZV (Ziekteverzekering) is sickness and health insurance for employees under the statutory wage threshold and is largely employer-funded, with the split noted above. OV (Ongevallenverzekering) is accident insurance covering workplace injury and is carried by the employer. Alongside these, the AOV/AWW old-age and survivors' pension has a maximum premium wage ceiling — reported by SZV as ANG 131,966.57 per year for 2025 — above which no further AOV/AWW premium is charged. Confirm the current ceiling and rates before you apply them, as the SZV Director publishes new pension amounts, premium percentages and maximum wage limits each year, effective 1 January. Our complete SZV premiums guide breaks down each premium in full.

Item	Figure (confirm current with SZV)	Where it applies
ZV premium — employer share	8.3%	Declared monthly via the portal
ZV premium — employee share	4.2%	Withheld and reflected in the declaration
OV premium — accident insurance	Employer-funded	Declared monthly via the portal
AOV/AWW maximum premium wage	ANG 131,966.57 / year (2025)	Ceiling above which no further AOV/AWW premium applies
Annual reset of rates & ceilings	Effective 1 January	Published each year by the SZV Director

Figures shown are as publicly reported and should be confirmed against SZV's current-year publications before filing.

Common submission errors and how to avoid them

Most portal problems are not exotic — they are the same handful of avoidable slips. Watch for these:

• Stale rates. Using last year's premium percentages or wage ceiling after the 1 January reset. Always pull the current figures before you calculate.
• Wages that don't match the payslip. The figure you declare should reconcile to each loonstrook; a mismatch invites a correction and a query.
• Unfiled mutations. A joiner or leaver recorded late throws off the premium base for the month. Update the workforce first, declare second.
• Missing the deadline. Late submission risks interest and penalties. Note the monthly due date in advance and file with time to spare.
• Ignoring the assessment. The assessment SZV returns is not just a receipt — reconcile it, and if it differs from what you declared, resolve it rather than leaving it to compound.
• Treating SZV as the whole picture. Your loonbelasting declaration to the Belastingdienst is separate and has its own timing.

How the SZV deadline lines up with wage tax

Your SZV declaration does not stand alone. In Sint Maarten, wage tax and premium declarations are generally due around the 15th of the following month, so the portal work and your loonbelasting filing to the Belastingdienst tend to fall in the same window. Treating them as one monthly close — payroll locked, SZV declared, wage tax filed, both paid — keeps the whole obligation tidy and reduces the chance of a missed deadline on either side. The precise dates and the cost of missing them are laid out in our 2026 payroll deadlines and penalties calendar. For employees who fall ill, the ZV side connects to benefits as well; see our guide to sick leave and ZV benefits. And for the full monthly picture end to end, our Sint Maarten payroll employer guide ties wage tax and SZV premiums together.
