As I mentioned... I did however provide a T4 slip which shows the earning in the previous year. I don't know if this helps or not.
Is there a link you may know of that you can provide me in which shows what both a notice of assessment and option C would look like? I have tried to look in Google images but it didn't help. If I see the difference, i would be able to know for sure which one I had sent.
Thanks for your time
