CRA dispute resolution refers to the processes available to individuals and businesses for resolving disagreements with the Canada Revenue Agency regarding tax assessments, audits, or other decisions. Disputes can arise from issues such as incorrect tax filings or adjustments made by the CRA. A taxpayer can initially request a formal review by the CRA by filing a Notice of Objection within 90 days of receiving the notice of assessment. If not resolved, taxpayers may appeal to the Tax Court of Canada. It is essential to gather relevant documentation and evidence to support your case and, if necessary, consider seeking professional advice or representation throughout the process.
