Health Care Spending Account (HCSA)

I have one, but never set it up, my employer did it with me.

You need to find a provider who administers these for small companies and owner incorporated businesses. An internet search turns up names such as olympia, thebenefitstrust, and EasyHSA and many other providers. You will need to pick a couple and make enquiries to find out more. They will charge an admin fee.

You'll find more about this in the Small Business forum. You do not need an administrator firm to set one up, you just need to follow the CRA rules to set it up properly so it is a tax-deductible expense to the company.

There are two reasons for hiring an outside firm to administer it though:
1) Ensure it operates in compliance with CRA rules, and have an independent party you can refer to if audited.
2) Ensure claims processing is impartial and confidential if there are multiple employees

Admin firms charge as little as 5% of claims. Some will also waive the setup fee if you ask.
