When to use T1213 instead of a TD1
Your TD1 covers standard credits such as the basic personal amount. The CRA's payroll guidance says a letter of authority is needed for other items, such as charitable donations, employment expenses, child care, RRSP contributions you make yourself, or working in a province other than the one you live in. To have more tax deducted, fill in a revised TD1 instead.
Common mistakes
- Using a T1213 to increase deductions; use a revised TD1 for that.
- Sending the form to your employer instead of the CRA.
- Leaving out supporting documents.
- Using last year's form.
