Premiums and payment

Your premium rates are based on the shared risk of all the businesses that do the same type of work in your class. We also look at your individual claims history compared to the rest of the businesses in your class. The premiums you pay are used to pay benefits to people who are injured or become ill in the workplace. So, preventing injuries and getting injured employees back to work quickly reduces costs for everyone.

Paying premiums is a two-step process

To report your premium and make premium payments log into our online service.

Premium reporting Payment

Our online service for premium reporting helps you accurately calculate and report your payroll information.  Even if your payroll is zero, you must report.

  • Enter your insurable earnings and you’ll receive an automatic calculation of your premium. You will also have the option to view your premium transactions online anytime.

You can also:

  • Calculate and report your premium using the bottom portion of the remittance form and mail it with your payment using the return envelope.  You can also drop it off at your local WSIB office before the due date.

Premiums not reported by the due date will result in a non-compliance charge.

For more information on determining your insurable earnings see, calculating your premium payments  and our policy on determining insurable earnings.
