Can I add T4s after I submitted them?

Hi there, 

I know how important it is to get all your year-end tasks done so you're organized and up-to-date with your books. I want to make sure I'm on the same page so I can provide you the best possible information. 

Where do you want to add a T4? Which version of Payroll are you using?

If I have a bit more information, I'd be happy to get you back on track. 

I'll be on standby.
