My payroll details for the tax years are not showing for me to email wage slips to employees?

Hi there, @l-bigwood.

I can help you check if this is a browser-related issue that has causing you not to be able to see the tax years in the Payroll Details (Gross To Net) Report. 

First, login to QuickBooks Online using an incognito browser. If you're able to see the information in the report, you can go back to your regular browser and clear the cache. If it's still the same, use another supported browser as an alternative.

Here are the keyboard shortcuts to access a private browser:

• Google Chrome: Ctrl + Shift + N
• Microsoft Edge & Mozilla Firefox: Ctrl + Shift + P
• Safari: Hold down ⌘ + Option + P 

You can also invite them to QuickBooks Workforce to let them view all their payslips from the date that they start working in your company. To know more on how to set it up, you can check out this article: Allow employees to view and download payslips in QuickBooks Workforce.

I'll be here if you need further assistance. Let me know in the comment section below. Take care.
