1. Overview of CRA Form TD1 Personal Tax Credits Return
Form TD1 (Personal Tax Credits Return) is an official CRA tax form filled out by employees when starting a new job in Canada to determine the correct amount of federal and provincial income tax to be withheld from their paychecks.
Key Policy Highlights & Benchmarks
- Federal Basic Personal Amount 2026 (Income-Tested): The 2026 federal basic personal amount ranges from $14,829 (for higher-income earners) to $16,452 (for lower-income earners) depending on net income. The phase-out applies to income above approximately $174,000.
- Two Required Forms: Every new employee must complete BOTH a Federal Form TD1 and a Provincial Form TD1 (e.g. TD1ON for Ontario, TD1BC for BC).
- Claiming Additional Tax Credits: Increase your tax-free threshold by claiming tuition amounts, disability amounts, spouse amounts, or caregiver credits.
- Multiple Employer Warning: If you have 2 jobs simultaneously, you can claim the Basic Personal Amount on ONE TD1 form only (tick 'More than one employer' box on second job).
