Greetings.. Question 1. I’ve been living overseas as an expat for 19 years. My gross Canadian income from CPP & OAS benefits totals $17855. I have no other Canadian income. Per the NR4 my OAS Non-resident tax withheld was $2643.75. As for CPP no Non-resident tax withheld. Based on the minimum tax credit, do I owe any tax based on my CPP benefit was not taxed? Question 2. What is the cost for completing my tax return and how do we go about doing this (I’m overseas) The deciding factor of having your firm complete the necessary return is dependent on your cost and whether I can expect a refund based on my Canadian CPP/OAS declared income.
