I want to add tips to a self employed ethician who is a GST registrant so she doesn't collect GST on the tips, just her sales. When she files her GST return, she includes her sales that she collected on, but not her tips so when I do her tax return, I want to make sure that the tips are included in income, but make it clear that GST is not collectable on that amount. I want to add the tips to line 8230 on the T2125, but I can only override that line-it won't open to allow me to specify...
