Many Canadians expecting quick tax refunds in April 2026 may face unexpected delays due to increased review activity by the Canada Revenue Agency. While refunds are typically processed within one to two weeks for electronic filings, a rising number of taxpayers are receiving review letters instead of payments
What a CRA Review Means in 2026
A CRA review is a routine verification process—not a full audit. The agency selects certain tax returns to confirm that reported income, deductions, and credits match information submitted by employers, banks, and other institutions.
In most cases:
- Only specific items on the return are reviewed
- A letter is sent via mail or through CRA My Account
- Taxpayers usually have 30 days to submit supporting documents
Refunds remain on hold until the requested documents are received and verified.
Why Refund Delays Are Increasing
Several factors are contributing to longer refund timelines in April 2026:
- Over 33 million tax returns expected this season
- Around 93% of Canadians filing electronically
- Increased reliance on automated risk detection systems
- Growth in gig economy income and cryptocurrency reporting
- Additional identity verification steps due to multi-factor authentication
These changes mean more returns are flagged for both pre- and post-assessment checks.
The Four Types of CRA Reviews
Understanding the type of review helps estimate processing time:
| Review Type | Timing | Purpose |
|---|---|---|
| Pre-Assessment Review | Before assessment | Verifies deductions and credits |
| Processing Review | After assessment | Checks submitted claims later |
| Matching Program | Before/after | Compares return with third-party data |
| Special Assessments | After assessment | Targets high-risk or non-compliant cases |
Pre-assessment reviews are the main cause of delays during April and May.
Who Is Most Likely to Be Reviewed
Certain taxpayers face a higher chance of being selected:
- Self-employed individuals with large expense claims
- People claiming high medical or charitable expenses
- Parents claiming childcare or dependent credits
- Newcomers filing their first Canadian return
- Seniors with multiple income sources
- Taxpayers reporting crypto, foreign income, or large capital gains
Significant changes compared to previous filings also increase the likelihood of review.
Common Triggers for CRA Checks
Returns may be flagged due to:
- Mismatches with employer or bank records
- Sudden increases in deductions or credits
- High-error categories like medical or employment expenses
- Suspicious login or banking activity
- Prior review history
Even accurate returns can be selected randomly.
Documents the CRA May Request
Depending on the claim, taxpayers may need to provide:
- Medical receipts and prescriptions
- Official donation receipts
- Childcare expense records
- Tuition slips (T2202)
- Moving or employment expense proof
- Rental income documentation
Documents are usually submitted digitally through CRA My Account.
How Long Does a Review Take?
A typical review timeline looks like this:
| Stage | Timeframe |
|---|---|
| Letter issued | Day 0 |
| Document submission | Within 30 days |
| CRA review | 4–8 weeks |
| Reassessment issued | After review |
| Refund processed | 5–10 business days |
Delays can extend to several months if documents are late or incomplete.
Impact on Benefits and Credits
A review can also affect government benefits, including:
- Canada Child Benefit (CCB)
- GST/HST Credit
- Ontario Trillium Benefit
- Canada Workers’ Benefit
- Guaranteed Income Supplement
Payments may be paused or recalculated until the review is completed.
How to Respond to a CRA Review
To avoid prolonged delays:
- Carefully read the review letter
- Gather all required documents
- Submit them through CRA My Account
- Include a clear explanation if needed
- Request an extension if unable to meet the deadline
Timely responses can significantly reduce processing time.
What Happens If You Ignore the Letter
Failing to respond can lead to:
- Denied deductions or credits
- Reduced or canceled refunds
- A balance owing with 7% interest (2026 rate)
- Higher chances of future reviews
Taxpayers have 90 days to file an objection if they disagree with the reassessment.
How to Reduce Review Risk in Future
To minimize future delays:
- Keep records for at least six years
- Match your return with CRA data before filing
- Report all income sources accurately
- Avoid unsupported claims
- Use electronic filing and direct deposit
- Monitor CRA My Account regularly
Proper documentation and consistency are key.
Conclusion
The increase in CRA reviews in April 2026 reflects a shift toward stricter verification and digital monitoring. While these checks are routine, they can significantly delay tax refunds if not handled promptly. Understanding the review process, responding quickly, and maintaining accurate records can help Canadians avoid unnecessary delays and ensure smoother tax filing in the future.
