Can't Pay Your Taxes? The CRA Has Options

If you're unable to pay your tax debt in full, don't ignore it. The CRA is willing to work with you. You can set up a payment arrangement to pay your debt over time. You can do this online through your CRA My Account using the pre-authorized debit service, or by calling the CRA's automated TeleArrangement service. Setting up a plan can help you avoid further interest and collection actions.
