Deal with it: Open all the brown envelopes you receive from the Canada Revenue Agency (CRA) promptly. If you receive a call from the CRA, return it. Ignoring the problem will not result in it going away. If you are being reviewed or audited, you need to respond and provide the information requested.
Meet the deadlines: If the CRA is reviewing your moving expenses, they will give you a due date for providing the documentation. Make sure you meet their deadlines. Even if you have the right paperwork, but you are late sending it, they will re-assess your return without the credit. Then you will have to file an adjustment to make the claim again.
