Need some help understanding Canadian tax statements from an experienced accountant? Here’s a quick guide to the T3, T4 and T5.
When filing taxes for the CRA or sending on your paperwork to your accountant, sometimes it feels like we only understand a small portion of what’s going on. As experienced accountants, we love to explain all the nuts and bolts that go into your tax return.
To this end, here’s a quick guide to your Canadian tax statements: the T3, T4, and T5.
Understanding Canadian tax slips is a critical part of filing an accurate personal or business tax return. These slips report income that has already been disclosed to the Canada Revenue Agency, which means mismatches between what you report and what the CRA has on file are one of the most common triggers for reassessments and review letters. Knowing what each slip represents, when you should receive it, and how it affects your tax return helps prevent errors and delays.
While T3, T4, and T5 slips are often discussed together, each one reports a different type of income and applies to different situations. Some taxpayers receive all three in a single year, while others may receive only one. Each slip has specific reporting rules, deadlines, and tax implications that are important to understand.
T3 Statement: Trust Income Allocations and Designations
A T3 statement is the statement of trust income allocations and designations. Its purpose is to tell both you and the Canada Revenue Agency (CRA) how much trust income was allocated or designated to you. This can include income from mutual funds, exchange-traded funds, estates, family trusts, real estate investment trusts, and other trust structures held outside registered accounts.
In practical terms, a T3 slip reports income you earned from a trust. This commonly includes income from mutual funds, exchange-traded funds, real estate investment trusts, and other trust structures held outside registered accounts such as RRSPs or TFSAs. The income reported on a T3 can include interest, dividends, capital gains, foreign income, and return of capital.
T3 income is often misunderstood because the cash you receive during the year does not always match the taxable income reported on the slip. For example, reinvested distributions may be taxable even if you did not receive cash. Capital gains reported on a T3 are taxable even when the underlying investment is not sold by you personally.
T3 slips are typically issued by the end of March, which is later than most other tax slips. This timing often delays personal tax filings for investors, particularly those with non-registered portfolios. If you file your return before receiving all T3 slips, you risk having to amend your return later.
For business owners and professionals with investment income, reviewing T3 slips carefully is important. Some amounts qualify for the dividend tax credit, while others are fully taxable. Foreign income reported on a T3 may also generate foreign tax credits, which must be claimed correctly to avoid double taxation.
T4 Statement: Employment Income and Benefits
T4 statements explain income earned.
A T4 slip reports employment income and taxable benefits paid by an employer. This includes salary and wages, overtime, bonuses, commissions, vacation pay, tips reported to the employer, and most taxable benefits such as automobile benefits or employer-paid insurance.
You will receive a separate T4 from each employer you worked for during the year. If you changed jobs or worked multiple positions, it is common to receive several T4 slips. All amounts must be reported on your personal tax return, even if you believe tax was already withheld correctly.
The deadline for employers to issue T4 slips is the last day of February following the calendar year. If that date falls on a Saturday, Sunday, or CRA-recognized public holiday, the deadline moves to the next business day. For 2025 slips issued during the 2026 filing season, the effective deadline was March 2, 2026. Employers who miss this deadline may face penalties, and employees should follow up promptly if a slip has not been received.
T4 slips include detailed boxes that affect how your tax return is calculated. CPP contributions, Employment Insurance premiums, income tax deducted, and pension adjustments are all reported here. Errors on a T4 can impact your RRSP contribution room, benefit eligibility, and refund or balance owing.
Other T4-Related Slips You May Receive
Other statements that fall under the T4 banner include:
T4A is a statement of pension, retirement, annuity and other income.
T4A (OAS) is the statement of old age security.
T4A (P) is the statement of Canada pension plan benefits.
T4E is the statement of employment insurance and other benefits.
T4RIF is the statement of income from a registered retirement income fund.
T4RSP is the statement of a registered retirement savings plan.
These slips cover income that is not employment-based but is still taxable. For example, independent contractors often receive T4A slips instead of T4s. Retirees commonly receive T4A OAS, T4A P, and T4RIF slips. Withdrawals from RRSPs are reported on a T4RSP.
Each of these slips has a different tax treatment. Some amounts may be eligible for pension income splitting or tax credits, while others are fully taxable. Understanding how each slip interacts with your overall income helps avoid missed opportunities and incorrect reporting.
T5 Statement: Investment Income
T5 is the statement of investment income. This includes any interest, dividends, and royalties you earned in the tax year.
T5 slips report investment income earned outside registered accounts. This includes interest from savings accounts and GICs, dividends from Canadian corporations, and certain foreign income. Financial institutions generally issue T5 slips when reportable investment income is $50 or more for the year. However, taxpayers are still required to report all taxable investment income, even if no T5 slip is issued.
Canadian dividends reported on a T5 may qualify for the dividend tax credit, which reduces the effective tax rate. Interest income is fully taxable at your marginal rate. Foreign income may generate foreign tax credits if withholding tax was paid.
For business owners, T5 income often overlaps with corporate distributions or shareholder loans. Careful review is necessary to ensure income is reported in the correct year and category.
How These Slips Affect Your Tax Return
The CRA receives copies of all T3, T4, and T5 slips directly from issuers. If an amount is missing or reported incorrectly on your return, the CRA’s matching system will typically flag it automatically. This often results in a reassessment, interest charges, or requests for documentation.
Reviewing each slip for accuracy before filing is essential. Common issues include incorrect social insurance numbers, missing slips, duplicate slips, or income reported in the wrong box. Addressing these issues early prevents delays and compliance problems.
Record Keeping and Deadlines
Taxpayers should retain copies of all slips and supporting documents for at least six years after the end of the tax year. Electronic copies are acceptable if they are readable and complete. Some records may need to be kept longer, such as documents related to long-term property ownership, objections, appeals, late-filed returns, or corporate records. If you discover an error after filing, an adjustment can be made through CRA My Account or with the assistance of a tax professional.
RRSP and TFSA Clarifications
A person can claim a tax deduction for the amount of contribution they make to their RRSP. There are limits and a few other things you need to know and understand.
RRSP deductions reduce taxable income, but the contribution room is limited and based on earned income and pension adjustments. Excess contributions can result in penalties if not corrected.
Also, you don’t have to have earned income to contribute to a TFSA, but those contributions cannot be deducted either.
TFSA contributions are not deductible, but investment growth and withdrawals are tax-free. Withdrawals do not affect taxable income or government benefits, making TFSAs a flexible planning tool for many Canadians.
When Professional Guidance Helps
Complex situations such as multiple income sources, trust distributions, investment portfolios, business ownership, or cross-border income increase the risk of reporting errors. Working with an experienced accountant helps ensure slips are reported correctly, deductions are maximized, and CRA requirements are met.
