Hi, @accounting703.
We can review your employee's tax settings if the tax exemption boxes are checked. That could be the reason why the taxes, Employment Insurance (EI), and Canada Pension Plan (CPP) were not deducted.
Here’s how to do it:
- Go to My Apps.
- Hover your mouse over the Payroll section and click on Employee.
- Select the employee you want to review.
- Scroll down to the Tax Exemption section.
- Uncheck any boxes that were previously selected.

If all boxes are unchecked and the issue persists, we can troubleshoot your browser to determine if it's causing the problem.
Start by trying a different supported browser installed on your computer. You can also open an Incognito window by using the shortcut Ctrl + Shift + N. This will provide a fresh browsing session, free from old data that might be interfering with the page.
If you have additional concern, please reply to this post.
