Master the Essentials: Canadian Tax Filing Basics

The Canadian Tax Year and Key Deadlines

Most individuals file for the calendar year, with returns generally due at the end of April. If the date falls on a weekend or holiday, the effective deadline may shift to the next business day.

Self employed people typically have a later filing deadline, but any balance owing is still usually due around the end of April. Plan cash flow early to avoid last minute stress and interest.

Contributions made in the first sixty days of the year can usually be claimed for the previous tax year. Check your available room, set a reminder, and avoid overcontributing to keep penalties away.

Your Slips and Supporting Records

Look for forms such as T4 for employment income and T4A for other amounts. Match each slip to your records, and confirm that names, addresses, and totals align before entering them.

Your Slips and Supporting Records

Investment income often appears on T5 or T3 slips, while security transactions may be on T5008. Students may receive a T2202. Keep all pages, including summaries, since details affect credits and adjusted cost base.

Your Slips and Supporting Records

Keep receipts and files organized, preferably for several years, in case the tax authority requests support. Many taxpayers now use Auto Fill My Return to import official slip data and reduce manual entry errors.

Taxable Income and the Basics

Start with all sources of income, then apply eligible deductions to reach taxable income. The Basic Personal Amount and other non refundable credits reduce tax payable, but do not create refunds on their own.

Common Deductions to Watch

Child care expenses, certain moving costs when you relocate for work or school, and union or professional dues may be deductible. Always read eligibility rules closely and keep receipts that clearly show dates and amounts.

Popular Credits and Benefits

Look into the GST HST credit, Canada Workers Benefit, disability related credits, and provincial programs. Eligibility often depends on income and family status, so update marital information and dependants accurately when filing.

RRSP Basics and Simple Tax Planning

How RRSP Deductions Work

RRSP contributions can reduce taxable income when claimed, potentially lowering your tax bracket. Confirm contribution room on your Notice of Assessment and consider timing contributions to match your expected income level.

TFSA Versus RRSP Context

A TFSA does not give a deduction, but growth and withdrawals are generally tax free. While TFSA details are not usually reported on your return, staying within limits prevents penalties and protects future flexibility.

Spousal Strategies and Special Programs

Spousal RRSPs can shift future taxable withdrawals, supporting household planning. Programs like the Home Buyers Plan and Lifelong Learning Plan allow eligible RRSP withdrawals, but repayment rules matter, so track schedules carefully.

Reporting Business Income

If you run a sole proprietorship or side gig, you typically report using a business schedule that summarizes revenue and expenses. Keep invoices, mileage logs, and receipts to support each number you enter.

Common Expenses and Home Office

Legitimate business costs may be deductible, including supplies, advertising, and a reasonable home office portion if you meet eligibility tests. Choose a consistent method and document calculations to handle reviews confidently.

Sales Tax and Contributions

Some businesses must register to collect GST HST once they exceed small supplier thresholds. Self employed individuals also plan for Canada Pension Plan contributions and may need instalments to avoid interest and penalties.

Newcomers, Residency, and Life Changes

Residency for tax purposes depends on your ties to Canada and can differ from immigration status. Newcomers may report worldwide income from the date they become residents, so keep entry dates and foreign documents ready.
