For some people the hardest part of doing their income taxes is waiting for an expected refund.
It depends when and how you file your income tax return how soon you can expect to receive a refund if you had too much tax withheld or have more refundable credits than taxes owed. If you file your taxes electronically (using NETFILE or EFILE) your return may be processed in as little as eight days. A paper return takes longer. In any case, most returns are processed within two to six weeks.
It's possible that your return may be selected for a more detailed review and the Canada Revenue Agency (CRA) may ask you to send them documents to verify deductions or credits you claim. In that case your assessment, and possible refund, may be delayed.
The CRA asks that you wait for at least four weeks after you file your income tax return before you check on the status of your refund. Here's information on normal income tax processing times, and how to check on your tax refund in Canada online or by phone.
