The short answer

Form TD1, the Personal Tax Credits Return, is how a Canadian employee tells their employer which tax credits to apply when calculating income tax withholding. There is a federal TD1 and a provincial or territorial version, and most employees complete both on hire. Employers keep the forms rather than sending them to CRA. Workzoom applies the claimed credits on every pay run from the employee record.

How Form TD1 works.

The TD1 determines withholding, not the final tax bill, which is settled on the employee's return. Employees complete a new TD1 when their situation changes, and the employer applies it from the next pay run. Where no TD1 is filed, the employer applies the basic personal amount only. Because federal and provincial forms are separate, an employee moving province mid-year needs a new provincial TD1 even though the federal one is unchanged, which is the detail most often missed on an internal transfer.

Questions about Form TD1

No. The employer keeps the TD1 on file and uses it to calculate withholding. It is not routinely submitted to the Canada Revenue Agency.
Yes, in most cases. There is a federal TD1 and a separate provincial or territorial version, and both feed the withholding calculation. An employee changing province needs a new provincial form even if their federal claim is unchanged.
Claiming the basic personal amount with more than one employer generally leads to under-withholding, because each employer calculates as though it were the only income source. The TD1 instructions direct employees with multiple employers not to claim the amount twice.
