About CRA Form TD1ON, Ontario Personal Tax Credits Return
The TD1ON, Ontario Personal Tax Credits Return, is the provincial companion to the federal TD1. If you work in Ontario, you give it to a new employer or payer alongside the federal form so the Ontario portion of your income tax is worked out correctly. It lists the Ontario credits you can claim, and the total sets how much provincial tax comes off your pay.
You usually fill it out when you start a job in Ontario, when your situation changes, or when you want more tax held back. The Ontario basic personal amount and the other credit values are printed on the current form and differ from the federal figures, so read each line before you enter anything. This page is a free fillable helper and general guide, not tax advice, so always download and file the current official form from the CRA.

Frequently asked questions
Do I need the TD1ON as well as the federal TD1?
Yes, if you work in Ontario. You complete the federal TD1 and the TD1ON together, because the Ontario credits and amounts are separate from the federal ones.
Do I send the TD1ON to the CRA?
No. You give the completed TD1ON to your employer or payer, who keeps it on file and uses it to set your Ontario tax deductions. You do not mail it to the CRA.
What is the Ontario basic personal amount?
It is the amount most Ontario residents can claim in full, and it is different from the federal basic personal amount. The current figure is printed on the form, so use the value shown there.
What is the Ontario caregiver amount?
It is a provincial credit for people who support a spouse, common-law partner, or dependant with an impairment. Claim it only if you meet the CRA conditions, and use the amount printed on the current form.
What if I have more than one employer in Ontario?
You usually claim the personal amounts on only one TD1ON and tick the box on the others so tax is held back correctly. The instructions on the form explain this.
Is this the official CRA form?
This is a free fillable helper and general guide. Amounts change each year, so always download and file the current official TD1ON from the CRA before you rely on it.
