it is indeed that simply. You need to prove to them $80k income by any of the means i mentioned. If your income is non-taxable, the obviously they won't see it on a tax return will they?? They are not going to take your word for it. So you need to supply the statements from FER's in addition to the tax and clearly demonstrate to them the non-taxable portion. It's even easier for them in that case, as long as you supply the correct documents.
