Your partner in a fair HRA premium
Security without financial risk
Why (have it) checked?
At the end of the year, the Tax and Customs Administration announces the new Differentiated Workforce Investment Fund (WHK) premium. This premium determines how much your organization will pay in the coming year for the risk of Sickness Benefits Act and WGA costs.
The WHK premium is a direct cost for you as an employer and is recalculated annually based on data from the UWV. The announcement of the new premiums is the time to check carefully whether the premium has been set correctly.
Every year, over 40% of calculations are found to contain errors. An incorrect allocation, an error in the wage bill or an incorrect sector classification can lead to an unnecessarily high premium. And that's something you want to avoid.
Frequently asked questions about the WHK premium
The work resumption fund (WHK) raises questions for many employers. What determines the amount of the premium, how is it calculated and what factors play a role? Below you will find clear answers to the most common questions.
What exactly is the WHK premium?
- Sickness Act (ZW): for employees without a permanent employment contract who leave employment sick or become sick within their flex contract.
- WGA (Work Resumption Partially Disabled): for long-term sick or partially disabled (former) employees.
How is the HRA premium calculated?
- The amount of your wage bill,
- The sector in which your organization is classified,
- and benefit costs of (former) employees attributed to your organization.
Are those details incorrect? Then you will automatically pay more premium than necessary.
Why do I need to check if my WGA beneficiaries are still in the correct WIA class or category?
Because UWV has long been unable to handle the demand for socio-medical assessments, large backlogs have developed. As a result, clients often have to wait much longer than the statutory eight-week period.
For you, this means that WGA beneficiaries attributed to your organization may not be assessed and supervised in a timely or adequate manner. As a result, they may unfairly remain in the wrong WIA class (disability percentage) or category (WGA or IVA).
If you do not actively monitor this, you will soon pay too much WGA premium. That's why it's important to stay keen on assessing your WGA files yourself.
For whom is it important to properly monitor the HRA premium?
Medium and large employers in particular would be wise to actively monitor their WHK premiums. This is because for these groups, the premium is calculated on a differentiated basis: the higher the influx into the Sickness Benefits Act (ZW) and the WGA, the higher the premium.
Are you a medium-sized employer? Then you pay a premium that depends partly on your sector and partly on your own inflow into ZW and WGA. For large employers, only the individual risk is decisive. By limiting the inflow and the cost of claims, you can immediately realize substantial savings on your WHK premium.
Small employers receive a sectoral premium that is not individually controllable. Still, even for them, monitoring can be useful to understand what factors determine their premium and to detect possible errors.
What does it mean if my organization is self-insured?
Organizations can choose to become self-insurer for the Sickness Benefits Act and/or the WGA. In that case, they do not pay a differentiated premium to the Tax Office, but bear the financial risk and reintegration obligations of sick or disabled (former) employees themselves.
