Appealing a CRA tax decision? Our tax lawyers represent individuals and businesses in Tax Court of Canada appeals and tax litigation.

Appealing a CRA Tax Decision to the Tax Court of Canada?

If you disagree with the outcome of a Canada Revenue Agency (CRA) objection, you may have the right to appeal the disputed assessment or reassessment to the Tax Court of Canada.

The Tax Court of Canada is an independent federal court that hears appeals involving income tax, GST/HST, and certain other matters within its jurisdiction. Tax Court litigation is a separate stage from the CRA audit and objection processes and involves formal court procedures, evidence, legal submissions, and ultimately a decision by a judge.

At KR Law Firm, our tax lawyers represent individuals, businesses, and corporations in Tax Court appeals and related tax litigation. We can assess the CRA’s position, prepare the Notice of Appeal, develop the evidentiary record, conduct litigation, negotiate where appropriate, and represent clients at hearings and trials.

When Can You Appeal to the Tax Court of Canada?

For many income tax and GST/HST disputes, a taxpayer must first file a Notice of Objection with the CRA before appealing to the Tax Court.

If CRA Appeals confirms the assessment, issues a reassessment, or otherwise decides the objection and the taxpayer continues to disagree, an appeal to the Tax Court may be available.

In certain circumstances, a taxpayer may also be able to appeal to the Tax Court if the CRA has not decided the objection within the applicable statutory period.

For income tax objections, an appeal may generally be available once 90 days have passed after the Notice of Objection was filed without a CRA decision.

For GST/HST objections, an appeal may generally be available once 180 days have passed without a CRA decision.

Tax Court of Canada Appeal Deadlines

Tax Court appeal deadlines are statutory and should be reviewed carefully.

For many income tax and GST/HST matters, an appeal must generally be filed within 90 days from the date of the CRA’s notice of confirmation, reassessment, or redetermination following the objection process.

Missing the appeal deadline does not always mean that the right to appeal is permanently lost.

In some circumstances, an application may be made to the Tax Court for an extension of time to appeal. For many income tax and GST/HST appeals, the extension application must generally be made within one year and 90 days from the applicable CRA decision and must satisfy the statutory requirements.

If you have received a CRA objection decision or have missed the 90-day Tax Court appeal deadline, it is important to obtain legal advice promptly.

What Is a Notice of Appeal?

A Notice of Appeal formally starts the Tax Court proceeding.

The content and procedural requirements depend in part on whether the appeal proceeds under the Informal Procedure or the General Procedure.

A Notice of Appeal generally identifies:

  • The assessment, reassessment, or decision being challenged;
  • The taxation years or reporting periods in dispute;
  • The material facts relevant to the appeal;
  • The issues to be decided by the Court;
  • The legal basis for the taxpayer’s position; and
  • The relief being requested.

The way an appeal is pleaded can affect the scope and conduct of the litigation, particularly under the General Procedure.

Informal Procedure vs. General Procedure

The Tax Court hears many income tax and GST/HST appeals under either the Informal Procedure or the General Procedure.

The appropriate procedure depends on the nature and amount of the dispute and, in some circumstances, the taxpayer’s election.

Informal Procedure

The Informal Procedure is intended to provide a more simplified and flexible process for eligible disputes.

For income tax matters, a taxpayer may generally elect the Informal Procedure where:

  • The amount of federal tax and penalties in dispute does not exceed $25,000 per assessment;
  • The amount of a disputed loss does not exceed $50,000 per determination; or
  • Interest on federal tax or penalties is the only matter in dispute.

For GST/HST appeals, the Informal Procedure is generally available where the amount in dispute does not exceed $50,000.

There is generally no filing fee for an appeal commenced under the Informal Procedure.

Individuals may represent themselves or may be represented by a lawyer or another permitted representative.

General Procedure

Appeals that do not proceed under the Informal Procedure are generally heard under the General Procedure.

The General Procedure is governed by the Tax Court of Canada Rules (General Procedure) and involves more formal litigation procedures.

Depending on the case, the General Procedure may include:

  • Formal pleadings;
  • Documentary discovery;
  • Examinations for discovery;
  • Pre-trial motions or applications;
  • Expert evidence;
  • Settlement discussions;
  • A formal trial; and
  • Potential cost consequences.

Individuals may represent themselves or retain a lawyer. A corporation is generally required to be represented by a lawyer unless the Court grants leave for another arrangement.

General Procedure appeals are also subject to filing fees based on the amount in dispute.

What Happens During a Tax Court Appeal?

The precise litigation process depends on the procedure selected and the issues involved.

A Tax Court appeal may include the following stages:

1. Filing the Notice of Appeal

The taxpayer files a Notice of Appeal with the Tax Court of Canada within the applicable deadline.

2. The Crown Responds

The Attorney General of Canada, through Department of Justice counsel, represents the Crown and responds to the appeal.

Under the General Procedure, this typically involves formal pleadings setting out the Crown’s position and the assumptions relied upon in the assessment.

3. Documentary and Evidentiary Preparation

The parties identify and organize relevant documents, financial records, agreements, correspondence, expert evidence, and other evidence required to prove or defend the issues in dispute.

4. Discovery and Pre-Trial Proceedings

General Procedure cases may involve examinations for discovery, document production, motions, case management conferences, settlement discussions, and other pre-trial steps.

5. Settlement Discussions

Tax disputes can sometimes be resolved before trial where the parties reach an agreement that is legally supportable based on the facts and applicable tax law.

Where a settlement is not possible, the matter proceeds toward trial.

6. Tax Court Hearing or Trial

At trial, the parties may call witnesses, introduce documentary evidence, cross-examine witnesses, present expert evidence where appropriate, and make legal submissions to the Court.

7. Tax Court Decision

After considering the evidence and legal arguments, the judge may issue a decision orally or in writing.

Depending on the case, the Court may allow the appeal, dismiss the appeal, or refer the assessment back to the CRA for reconsideration and reassessment in accordance with the Court’s judgment.

How Our Tax Lawyers Assist With Tax Court Appeals

1. Review the CRA Objection Decision and Record

We review the assessment or reassessment, CRA audit findings, Notice of Objection, CRA Appeals correspondence, supporting evidence, and the decision being challenged.

This helps identify the factual and legal issues that should form the basis of the Tax Court appeal.

2. Develop the Litigation Strategy

We assess the strengths and weaknesses of the case, determine the evidence required, identify potential witnesses, and develop a litigation strategy based on the issues before the Court.

3. Prepare and File the Notice of Appeal

We prepare the Notice of Appeal and other required court documents, ensuring that the relevant issues, facts, legal grounds, and relief sought are properly identified.

4. Manage the Litigation Process

Depending on the procedure and complexity of the matter, we can assist with pleadings, documentary discovery, examinations for discovery, motions, settlement discussions, witness preparation, expert evidence, and other procedural steps.

5. Represent Clients at Hearings and Trial

Our tax lawyers can present evidence, examine and cross-examine witnesses, make legal submissions, and advocate for the taxpayer’s position before the Tax Court of Canada.

6. Advise on the Decision and Further Appeal Rights

After a Tax Court judgment is issued, we can review the decision and advise on its implications, implementation, and any further appeal rights that may be available.

Tax Court Appeals Following a CRA Objection

A Tax Court appeal commonly begins after a taxpayer has completed the CRA objection process but remains dissatisfied with the outcome.

The Notice of Objection and the positions taken before CRA Appeals can become important when the matter proceeds to litigation. The evidentiary record developed during the audit and objection stages may also affect how the Tax Court case is prepared.

If you have not yet filed an objection to the CRA’s assessment or reassessment, learn more about our CRA tax objection services.

Tax Court Appeals Following a CRA Audit

Many Tax Court disputes can be traced back to adjustments first proposed during a CRA audit.

The audit may create the factual record surrounding issues such as unreported income, denied expenses, GST/HST, real estate transactions, shareholder benefits, net worth assessments, or other disputed tax matters.

If you are still at the audit stage, learn more about our CRA audit representation.

Income Tax Appeals

Tax Court income tax appeals may involve issues such as:

  • Unreported or disputed income;
  • Business income and deductible expenses;
  • Capital gains versus business income;
  • Shareholder benefits and shareholder loans;
  • Real estate transactions;
  • Deductions and tax credits;
  • Foreign income and cross-border tax matters;
  • Tax residency issues;
  • Gross negligence or other penalties; and
  • Other assessments under the Income Tax Act.

GST/HST Appeals

Tax Court GST/HST appeals may involve:

  • Input tax credits;
  • Taxable, exempt, or zero-rated supplies;
  • GST/HST on real estate transactions;
  • Registration and remittance issues;
  • Documentation supporting input tax credits;
  • Allegedly uncollected GST/HST;
  • Penalties and interest; and
  • Other assessments under the Excise Tax Act.

Does Filing a Tax Court Appeal Stop CRA Collections?

Whether CRA collection activity is postponed during a Tax Court appeal depends on the type of tax and amount involved.

For many disputed income tax amounts, the CRA generally postpones collection action while the Tax Court appeal is pending.

However, important exceptions can apply, including certain GST/HST amounts, source deductions, and other liabilities that may remain collectible despite an ongoing dispute.

Interest may also continue to accrue on unpaid amounts while an appeal is pending.

If you are dealing with CRA enforcement, an outstanding tax balance, garnishment, liens, or other collection activity, learn more about our CRA collections and tax debt services.

What Happens After the Tax Court Makes a Decision?

Once the Tax Court issues its judgment, the parties must determine the legal and practical consequences of the decision.

Depending on the result, the CRA may be required to reassess the taxpayer in accordance with the Court’s judgment.

A party who believes the Tax Court made an appealable error may have the right to seek review by the Federal Court of Appeal.

Appeal deadlines at this stage can be short, so a Tax Court judgment should be reviewed promptly if a further appeal is being considered.
