In April 2026, the Canada Revenue Agency (CRA) is implementing new review processes that may significantly extend the time it takes for many Canadians to receive their tax refunds. Traditionally, Canadians who file their taxes electronically expect to receive their refunds within 8 business days to 2 weeks. However, this year, an increasing number of filers are receiving letters requesting additional documentation instead of their expected deposits.
As the April 30 filing deadline approaches with over 33 million returns anticipated, the CRA is conducting more thorough pre-assessment and post-assessment checks than in previous years. Understanding the reasons some returns are flagged, the documents that may be requested, and how to respond effectively can potentially save taxpayers from delays that may stretch from weeks into months.
What a CRA Review Actually Means in April 2026
A CRA review is a standard verification process, not an audit. Each year, the CRA randomly selects a portion of tax returns to ensure that the deductions, credits, and reported income align with the information they receive from employers, banks, and other third parties. Typically, these reviews focus on specific claims rather than the entire tax return.
When selected for a review, taxpayers will receive a letter via mail or in their CRA My Account inbox. This letter will specify the deduction, credit, or income amount under scrutiny and will provide a deadline, usually 30 days, for submitting the necessary supporting documents. Until the CRA receives and processes these documents, any associated refunds or Notices of Assessment will be on hold.
Why Some Refunds May Get Delayed This Month
Several factors are contributing to increased refund delays for April 2026 filers:
-
- With 93% of Canadians filing taxes online in the previous year, the CRA has shifted its verification work to include more pre-assessment and post-assessment reviews, as electronic filings do not come with attached paper receipts.
-
- Returns that include unusually large claims are now identified by automated risk algorithms before a Notice of Assessment is issued.
-
- The introduction of mandatory multi-factor authentication has created new identity verification checkpoints, which can lead to temporary holds on refunds if any suspicious activity is detected.
-
- Higher volumes of newcomer filings, gig economy income reporting, and cryptocurrency disclosures are increasing the number of returns requiring a second review.
The 4 Types of CRA Reviews That Can Pause Your Refund
The CRA employs several review programs, and each operates slightly differently. Knowing which program has flagged your return can help you manage expectations regarding the resolution timeline:
-
- Pre-Assessment Review: Conducted before issuing your Notice of Assessment, it focuses on specific credits or deductions.
-
- Processing Review: Occurs after your Notice of Assessment, typically between August and December, and checks the supporting documents for already assessed claims.
-
- Matching Program: Can take place before or after assessment, focusing on discrepancies between your return and third-party slips.
-
- Special Assessments: Conducted after your Notice of Assessment to identify trends in non-compliance and high-risk files.
Who Is Most Likely to Face a CRA Review This Season
Certain taxpayers are more likely to be selected for reviews. Historically, these groups include:
-
- Self-employed individuals claiming significant business or home office expenses
-
- Taxpayers reporting large medical expenses, charitable contributions, or moving costs
-
- Parents claiming the eligible dependant credit or childcare expenses
-
- Newcomers filing their first Canadian tax return, especially those claiming tuition credits or foreign income exclusions
-
- Seniors with multiple pension sources or foreign income
-
- Individuals claiming the Disability Tax Credit or Canada Caregiver Credit
-
- Taxpayers with prior reviews resulting in adjustments to their returns
-
- Those reporting cryptocurrency transactions or significant capital gains
Moreover, returns that exhibit significant increases in claimed amounts compared to previous years are statistically more likely to be selected for review.
What Triggers a Post-Assessment Check
The CRA utilizes a mix of automated risk scoring and third-party data matching to determine which returns warrant further examination. Common triggers include:
Mismatches With Third-Party Slips
If the amounts reported on your return do not align with those submitted by employers or financial institutions, the Matching Program may flag your return for further scrutiny.
Significant Increases in Claims
Substantial increases in claims, such as a tripling of medical expenses or doubling of charitable donations, can prompt a review. The CRA seeks to verify these claims before processing refunds.
High-Error Deduction Categories
Certain claims, such as medical expenses and employment-related deductions, have historically shown higher rates of error and may trigger a review if combined in a single return.
Identity and Fraud Risk Signals
The CRA’s Identity Protection Services may flag accounts if it detects unusual login patterns or changes in banking information, potentially delaying refunds even if the tax return itself is accurate.
Prior Review History
If your return has been reviewed and adjusted in the past three years, the likelihood of another review increases significantly.
What Documents the CRA May Ask You to Provide
The specific documents required by the CRA will depend on the claims being reviewed. Typically, review letters will include a reference number that must be cited in your response. Common documents requested include:
-
- Medical Expenses: Prescriptions, pharmacy receipts, and practitioner statements
-
- Charitable Donations: Official receipts from registered charities
-
- Childcare Expenses: Receipts detailing care provider information and amounts
-
- Tuition and Education Amounts: T2202 slips and proof of enrollment
-
- Moving Expenses: Bills of lading and real estate commission statements
-
- Support Payments: Court orders and proof of payments
-
- Disability Tax Credit: Signed Form T2201 from a medical practitioner
Documents can be submitted securely through CRA My Account. The CRA recommends scanning documents in black and white to keep file sizes manageable.
Timeline From Review Letter to Refund Release
A review does not equate to a denial of your refund but does delay the timeline significantly. The general process includes:
-
- Letter Issued: Day 0 – CRA sends a review letter
-
- Response Window: Up to 30 days – Time to gather and submit documents
-
- CRA Review: 4 to 8 weeks after submission – Verification of documents
-
- Notice of (Re)Assessment: After review completion – Refund released or adjusted
-
- Refund Deposit: 5 to 10 business days after reassessment – Funds deposited or cheque mailed
If you cannot gather the requested documents in time, it is advisable to contact the CRA to request an extension before the deadline.
How Reviews Can Affect Your Benefit Payments Too
Additionally, a review can affect various income-tested benefits. The CRA uses the assessed return to recalculate benefits such as the Canada Child Benefit and GST/HST credit. While under review, these payments may be paused or adjusted based on income changes.
How to Respond to a CRA Review Letter Correctly
A well-organized response is critical to expediting the release of your refund. Follow these steps:
-
- Read the letter thoroughly and note the claim and reference number
-
- Collect all necessary receipts and supporting documents
-
- Log in to CRA My Account and use the Submit Documents feature
-
- Include a cover note explaining each document’s relevance
-
- Keep the confirmation number after submitting your documents
-
- If you need more time, contact the CRA before the deadline expires
Original receipts should not be sent unless explicitly requested, as the CRA does not return documents.
What Happens If You Ignore a Review Letter
Failing to respond to a CRA review letter can have serious consequences. If documentation is not submitted within the specified timeframe, the CRA may adjust your return, disallow claims, and issue a Notice of Reassessment reflecting a reduced refund or a new balance owing. Interest will begin accruing on any balance owed. Furthermore, neglecting to respond increases the chances of future reviews.
How to Reduce the Risk of a Review Next Year
While some reviews are random, you can mitigate your risk through diligent record-keeping and filing practices:
-
- Retain all receipts and supporting documents for at least six years after filing
-
- Use Auto-Fill My Return to ensure accuracy before submission
-
- Report all income sources accurately
-
- Claim only substantiated expenses
-
- File electronically through NETFILE to minimize errors
-
- Regularly check your CRA My Account for updates
-
- Update personal information before filing
-
- Provide explanatory notes for significant changes in claims
Timely and thorough engagement with CRA reviews can lead to quicker resolution, often within a few weeks instead of stretching the process across an entire year.

To expedite your refund, file electronically, ensure all information matches CRA records, and respond quickly to any review requests. Regularly check your CRA My Account for updates.
How long can the CRA hold my refund during a review?
Pre-assessment reviews typically take 4 to 8 weeks to resolve after document submission, but delays can extend if the review is complex or if deadlines are missed.
Can I still receive my benefit payments while my return is under review?
Benefit payments usually continue based on previous assessments until the review is complete. However, if your income changes after reassessment, future payments may be recalculated.
What should I do if I lost the receipts the CRA is asking for?
Contact the issuer for duplicates or alternative proof. If unavailable, reach out to the CRA to explain your situation; they may accept bank statements or credit card records as evidence.
Reality Check
It is crucial to understand that while reviews are a routine part of the tax process, they can lead to significant delays in refunds and impact benefit payments. Taxpayers should maintain thorough records and respond promptly to any CRA inquiries to mitigate risks. Relying solely on assumptions about the review process without verifying current information on the official CRA website may lead to unexpected complications. Always consult the official sources for the most accurate and up-to-date information regarding your tax situation.
