With the April 30, 2025, tax filing deadline fast approaching, Canadian taxpayers are facing a significant challenge: tax slips like T4s and T5s are missing from the Canada Revenue Agency’s online portals.
A new Canada Revenue Agency validation process introduced in January 2025 aimed to improve data accuracy but has instead caused widespread delays, leaving individuals and tax professionals scrambling.

What’s Behind the CRA Tax Slip Delays in 2025?
Every year, Canadian employers and financial institutions submit tax documents—such as T4 slips for employment income and T5 slips for investment income—to the Canada Revenue Agency by a set deadline.
The CRA then uploads these slips to online portals like CRA My Account, enabling taxpayers and tools like TurboTax to access them digitally.
However, a new validation process launched by the CRA in January 2025 has disrupted this system.
Designed to verify the accuracy of data from issuers, the process has instead resulted in missing or duplicated slips, with no clear resolution in sight as the filing deadline looms.

A CRA spokesperson stated, “We are actively working to resolve these issues and collaborating with issuers to ensure tax slips are available on the portal.”
The agency had promised The Globe and Mail a fix by mid-April, but when pressed by CBC for updates, the CRA provided no concrete progress.
Tax expert Kim G. C. Moody of Moodys Tax notes that while some slips are now appearing, many remain unavailable, and duplicates are adding to the confusion.
The issue appears random, affecting various slip types and issuers unpredictably.
Key Takeaways:
New Validation System: Rolled out in January 2025 to ensure data accuracy.
Current Problem: Missing and duplicated slips on CRA My Account.
CRA’s Efforts: Ongoing collaboration with issuers, but no firm timeline for a fix.
Random Impact: No specific slip type or issuer consistently affected.
How Missing Tax Slips Impact Your 2025 Tax Filing
The absence of digital tax slips doesn’t excuse you from the April 30 deadline, especially if you owe taxes.
Here’s how this issue affects different groups and what you can do to stay on track.
For Individual Taxpayers
If you use tax software like TurboTax or Wealthsimple, the missing slips mean you can’t rely on the autofill feature, forcing manual data entry.
This increases the risk of errors, such as underreporting income or missing deductions.
Shari-Lynn Hiltz, a Halifax-based certified bookkeeper, recommends verifying your income by comparing your T4 with your final 2024 paystub and contacting financial institutions to ensure you have all slips.
Steps to File Without Digital Slips:
Collect Physical Copies: Employers and financial institutions send you copies of your slips. Check email, online banking, or employee portals, or wait for mailed versions.
Manual Entry: Enter data into your tax software line by line, ensuring accuracy.
Verify Income: Cross-check all income sources with paystubs or bank statements.
File by Deadline: Submit your return by April 30 to avoid penalties, amending later if needed.
Potential Risks:
Incorrect Filings: Missing slips could lead to underreported income, triggering Canada Revenue Agency penalties.
Missed Savings: Overlooking slips might mean missing tax credits or deductions.
For Tax Professionals
The impact is even more severe for tax preparers.
Hiltz reports that nearly all her clients are missing at least one slip, forcing her to pause returns while clients gather documents.
Manual entry without autofill has slowed her down significantly, potentially delaying some filings past April 30.
Moody agrees, noting that processing times for complex returns could increase threefold or more, creating a bottleneck during peak season.
Why the CRA’s New Validation Process Is Falling Short
The CRA’s new system was meant to catch errors in tax slip data before it reached taxpayers, but its rollout has been problematic.
Experts like Moody highlight a troubling trend of CRA inefficiencies, pointing to past tax seasons disrupted by last-minute changes:
- 2023: A sudden extension for vacant property tax filings.
- 2024: A last-minute pause on bare trust filing requirements.
Moody calls for a “serious reflection” on the CRA’s technology and processes, arguing that these recurring issues undermine trust and efficiency.
The decision not to extend the 2025 deadline adds further pressure on taxpayers and professionals.

Work with Your Accountant:

Confirm their timeline to ensure timely filing.
File Even If Incomplete:
If you owe taxes, file with the data you have and amend later.
The CRA allows corrections after submission.
Bypass Autofill:
Be ready to manually input data into tax software.
Save your work frequently to avoid losing progress.
Stay Updated:
Regularly check CRA My Account for new slips.
Follow CRA announcements for resolution updates.
The Broader Issue: CRA’s Ongoing Technology Struggles
The 2025 tax slip issue is part of a larger pattern of CRA challenges:
Outdated Systems: The CRA’s digital infrastructure struggles with high demand and complex processes.
Poor Communication: Lack of clear updates on fixes frustrates taxpayers.
Past Disruptions: Recent tax seasons have seen last-minute changes, eroding confidence.
Moody urges the CRA to modernize its technology and improve internal processes to prevent future issues, emphasizing that taxpayers shouldn’t bear the brunt of these inefficiencies.
Avoiding Tax Filing Errors in 2025
With manual entry on the rise, errors are more likely.
Here’s how to minimize mistakes:
Cross-Check Income: Verify all sources against slips, paystubs, and statements.
Track Deductions: Ensure you claim all credits, like RRSP contributions.
Keep Records: Retain slips and CRA correspondence for at least six years.
Consider Professional Help: An accountant can help ensure accuracy if you’re unsure.
Hiltz stresses diligence: “Double-check everything now to avoid CRA audits later.”
What Happens If You Miss the April 30 Deadline?
If you owe taxes and file late, the CRA charges a 5% penalty on the balance owed, plus 1% per month for up to 12 months, with added interest.
To avoid this:
- File Partially: Submit what you have and amend later.
- Pay Estimates: If you can’t file, pay an estimated amount to reduce penalties.
- Request Relief: Contact the CRA to explain your situation, though no extension has been granted.
If you’re due a refund, there’s no penalty for late filing, but you’ll delay receiving your money.
File Smart Despite CRA Challenges
The CRA’s tax slip delays in 2025 are a major inconvenience, but they don’t have to ruin your tax season.
By collecting physical slips, verifying income, and filing on time, you can avoid penalties and errors.
Tax professionals are adapting to the challenge, and companies like TurboTax are advocating for solutions.
Stay proactive, monitor CRA updates, and seek help if needed to ensure a smooth filing process.
