A GST appeal refers to the process of contesting a decision made by the Canada Revenue Agency (CRA) regarding the Goods and Services Tax (GST) or the Harmonized Sales Tax (HST). If you disagree with a GST assessment, such as the amount of tax owed or a denial of input tax credits, you can file a Notice of Objection within 90 days of receiving the notice from the CRA. The appeal process involves a review of the decision, and if you’re not satisfied with the outcome, you have the option to take your case to the Tax Court of Canada. It’s advisable to maintain thorough records and, if needed, seek professional advice to navigate the appeals process effectively.
