Hello,
Setting up a new employee in QuickBooks Online is a really simple process that requires just a few steps. I know how vital it is to be able to enter and save all necessary employee details, especially their SIN which is needed to save them in the system. If you're unable to enter or save a SIN during the employee setup, I'll go through a few troubleshooting steps you can try.
Try clearing the cache and cookies to give your browser a reset. Stored Internet files build up over time as you browse, and they can cause bugs and other issues with sites like QuickBooks Online. Here's a list of steps explaining how to clear the cache and cookies based on your browser: Clear cache and cookies to fix issues when using QuickBooks Online.
If the issue continues to persist, try using an Incognito window in Google Chrome. This is a private window that runs separately from the rest of your browser, and it doesn't store cache and cookies the same way a regular browser would. Here's how to use it: Browse in private.
You can also try using a different browser all together.
If you're still running into issues, there may be something causing this on the back-end, and I'd like our agents to take a closer look into this for you. I'd suggest reaching out to our tech support team directly, and I'm confident an agent can sort this out for you.
I hope this helps.
Take care.
