T1 Personal Return Overview

Definition

The T1 General Income Tax and Benefit Return reports personal income, deductions and credits and reconciles tax already withheld or paid in instalments. Canadian residents generally report worldwide income; the obligation to file depends on the individual’s circumstances. The T1 generally covers federal and provincial or territorial income tax, based on the individual's December 31 residence. Quebec residents also file a separate provincial return with Revenu Québec. For owner-managers of a Canadian-controlled private corporation (CCPC), the T1 is where salary (T4), dividends (T5), interest, capital gains, and rental or self-employment income are all pulled together.

Key rules

• Filing deadline is April 30 of the following year for most individuals. Qualifying self-employed filers and their spouse or common-law partner generally have until June 15, but the usual payment deadline remains April 30. Tax-shelter businesses, deceased taxpayers and other special situations have separate rules; weekend and recognized-holiday extensions can apply.
• Non-resident filing obligations depend on the type of Canadian-source income and applicable treaty. Correct Part XIII withholding is generally the final Canadian tax on that income unless a permitted election applies. Use CRA’s non-resident guidance, not the resident rules by default.
• Income is classified into five buckets under ITA s.3: employment, business, property, capital gains, and "other" (support payments, RRSP withdrawals, etc.).
• Most federal personal non-refundable credits, including the Basic Personal Amount, use 14% for the 2026 tax year and 14.5% for 2025. Other credits, such as the dividend tax credit, have their own formulas. Deductions reduce taxable income directly. See CRA's current rates.
• Instalment payments are required when federal plus provincial net tax owing exceeds $3,000 ($1,800 in Quebec) in the current year and either of the two prior years.
• Generally keep supporting records for six years after the end of the relevant tax year. Late-filed returns, unresolved objections and long-term asset records can require a longer retention period.

Example

A BC resident earns $85,000 in T4 salary from her CCPC, receives $20,000 in non-eligible dividends reported on a T5, and makes an eligible $10,000 RRSP contribution in February of the following year. This simplified bridge assumes enough RRSP deduction room and shows only that deduction; enhanced CPP and any other deductions must also be applied on the actual return.

Line 10100  Employment income             $85,000
Line 12000  Taxable amount of dividends   $23,000   (gross-up 15%)
Line 15000  Total income                 $108,000
Line 20800  RRSP deduction               ($10,000)
Subtotal before other deductions        $98,000
Line 40425  Federal dividend tax credit    $2,076.92

The dividend credit is $23,000 × 9.0301%, rounded to $2,076.92, using CRA’s T5 instructions. The corporation already remitted source deductions on salary and issued a T5 for dividends. The T1 reconciles what has been paid against total tax owing at combined federal and BC rates.

Common mistakes

• Missing the June 15 deadline while assuming the balance is not due until then. Interest starts May 1 on any unpaid amount.
• Forgetting to report taxable dividends because no tax was withheld or no T5 arrived. CRA generally does not require a T5 when the total paid to one recipient for the year is less than $50, but the recipient must still report the income. See CRA’s T5 filing exceptions.
• Missing Form T1135 when the total cost of specified foreign property exceeds $100,000 at any time in the year. Personal-use property, registered-plan holdings and other exclusions matter. Check CRA’s T1135 requirements rather than treating all foreign property as reportable.
• Claiming a newly made RRSP contribution against the preceding year after that year’s first-60-days contribution deadline. A later contribution may qualify for the current or a future year, subject to the deduction limit; previously reported unused contributions can also be deducted later.
• Deferring a capital disposition to a later reporting year without checking the rules. Individuals generally report a disposition in the calendar year they sell or are considered to have sold the property. See CRA’s capital-gains reporting guidance.

Related concepts

The T1 sits at the end of the personal tax cycle. Before it come the federal tax brackets that determine the rate on each layer of income, the choice between deductions and credits, and the Basic Personal Amount, subject to income and residency rules. Owner-managers also rely on the eligible versus non-eligible dividends treatment and, where applicable, the foreign tax credit to avoid double taxation.
