After filing your taxes, it doesn’t mean you can get rid of your receipts and documents. The CRA (Canada Revenue Agency) suggests keeping those documents for six years after your last Notice of Assessment. This may seem like a long time to hold onto the paperwork. However, there are situations where you may be required to provide these documents within that time frame, like being audited. The CRA can only audit you four years after filing, but keeping them for six is recommended.
