I know I have made a mistake of my income tax but it has been netfiled why do I have to wait till I have received a NOC number to correct this?

I know that I have made a mistake on my income tax which has been netfiled why must I wait till I get a NOA  number before altering it? I only netfiled it 2 days ago.


CRA requires you to wait until you receive your Notice of Assessment before making any changes to it for a number of reasons. Often times you may have submitted/NetFiled your return and CRA catches the error or missing slip and corrects it for you before assessing the return. If they do make any changes or corrections to the return you filed, it will say in the Notice of Assessment you receive.

Once you receive that NOA, you can proceed with your T1 Adjustment if necessary.

People come to TurboTax AnswerXchange for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:

  1. Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
  2. Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
  3. Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
  4. Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
  5. Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
