The deadline to file personal income tax returns with the Canada Revenue Agency (CRA) is April 30, 2025, which means the best time to organize your tax slips is now.
The deadline also applies to self-employed individuals who have a later filing deadline because taxes owed are still due on April 30 even though the form itself doesn’t need to be filed until June. Normally the due date for these returns is June 15, but in 2025, the filing deadline is June 16, since June 15 is a Sunday.
Getting your taxes done early helps you avoid stress and painful penalties.
When to expect your tax slips?
You should receive most of your slips and receipts by the end of February, although trust and partnership slips usually come in by the end of March.
Here's an overview of the filing deadlines for common tax slips:
- Reporting entities must send T4 employment income slips, T4A pension income slips, and T5 slips for investment income by Feb. 28, 2025.
- Trusts have a deadline of 90 days after the trust's year-end to report income to beneficiaries on T3 slips. As such, those with a 2024 calendar-year reporting period have until March 31.
- Partnerships must generally report partnership income to their partners on T5013 slips by March 31.
What to do with your tax slips?
The differing deadlines mean that you can still be receiving tax slips in April, and you may be inclined to set them aside until you receive all your expected documents and are ready to sit down with your tax return preparer.
Reject that inclination and take a more organized and itemized approach.
A written checklist or a personal tax organizer can keep track of the slips and receipts you expect to receive and can help you identify documents that may be missing. Assembling your slips and documentation will make verifying accuracy and catching any omissions easier.
What are the penalties for not reporting income?
Tax slips help you confirm that all sources of income are reported each year. They help ensure that you pay the appropriate amount of tax and avoid interest on underpaid tax. They also enable you to avoid the penalty for failing to report income.
For example, if you omit an income amount of $500 or more on your 2024 tax return, or on any of the 2021, 2022, or 2023 tax returns, you may face a penalty for failure to report income.
The federal and provincial or territorial penalties are each equal to the lesser of the:
- 10% of the amount you failed to report on your return for 2024; and
- 50% of the difference between the understated tax (and/or overstated credits) related to the amount you failed to report and the amount of tax withheld related to the amount you failed to report.

How to deal with missing tax slips?
Information slips are sometimes received late, or not at all. If this occurs, there is an increased risk of unreported income and associated penalties.
Here are three tips to help you avoid penalties, even if you are dealing with missing slips or receipts:
- Before filing, contact the issuer for any missing information slips or income receipts and request a duplicate. If you are a registered user of the My Account service offered by the CRA, you may be able to view your tax slips online and save yourself some time.
- If you are unable to locate the necessary information in time to file by the deadline, estimate the missing income amounts to the best of your ability. Supporting documents, such as pay stubs or account statements, may help you do this. Always retain your supporting information in case the CRA requests to see it. If necessary, you can request an adjustment to your tax return once the actual slips or receipts are received, and the amount of income is confirmed.
- Be sure to file on time to avoid late-filing penalties, even if you have yet to receive all your expected tax information slips or receipts for the 2024 reporting year. The CRA will not automatically waive penalties for late or inaccurate filing because of missing slips.
What about receipts for tax deductions?
While you could incur a penalty for missing an income slip and under-reporting your income, it is also important to keep track of slips that support income tax deductions or credits, such as charitable donation receipts and medical expense receipts.
Although tax slips for income are reported to the CRA and can be accessed using CRA’s My Account, the same is not true for charitable donation receipts or medical expense receipts. If you donate to several charities, it can be difficult to make sure that you have all the receipts to support your claim for donations, as they could be sent throughout the year when donations are received, or at the end of the year.
Late last year, the government announced that they would extend the deadline for donations that can be deducted on a 2024 personal tax return until February 28, 2025. On January 23, the CRA confirmed that it will proceed with administering this deadline extension for charitable donations on a one-time basis for 2024 tax returns.
Note that this extension only applies to donations made in cash or by way of cheque, credit card, money order, or electronic payment. Also, charities will not be required to change their normal process to issue an official receipt for donations made during January and February 2025 if their normal practice is to issue annual receipts only. In such a situation, you can still claim the donation on your 2024 tax return, but keep a copy of your payment until the donation is acknowledged in an official 2025 statement from the charity.
Setting up an electronic or paper folder at the start of each year can help to keep the receipts all in one place so they are easy to find when you are getting ready for your tax preparer. The same idea works well for medical receipts. While these receipts do not have to be submitted to the CRA with your tax return, the CRA could ask for copies if they are conducting a post-assessment review of your return.
Don't let a third party's oversight add to your tax bill. Taking the time to manage and collect your information slips and tax receipts before filing your income tax return can help you avoid paying unnecessary taxes, interest, and penalties.
