Starting a job in Ontario usually means completing two forms on day one: the federal TD1 and Form TD1ON, the Ontario Personal Tax Credits Return. The TD1ON covers the provincial side of your payroll deductions, telling your employer or pension payer how much Ontario income tax to withhold based on the provincial credits you expect to claim for the year. It is completed in addition to the federal TD1, never instead of it.
Universal PDF lets you fill out the TD1ON entirely in the browser. Load the current year's form in the editor, enter your Ontario claim amounts, sign, and download the finished PDF for your employer, payroll department, or HR system.
What is Form TD1ON used for
Ontario collects its own personal income tax, and the TD1ON is how your payer learns which Ontario non-refundable credits apply to you. Your total claim amount from the form feeds into the provincial payroll deduction tables, so a higher claim means less Ontario tax taken off each pay and a lower claim means more.
Ontario's credit list is shorter than the federal one. The province replaced its separate caregiver and infirm dependant credits with a single Ontario caregiver amount, and it no longer offers a provincial tuition credit, so the TD1ON has no tuition line even though the federal TD1 does.
Who fills out Form TD1ON
For employment income, the provincial form follows your province of employment rather than where you live. If you report to your employer's Ontario location, you complete the TD1ON even if you commute from Quebec or Manitoba. Pension income works the other way: pensioners complete the form for the province where they reside.
Strictly speaking, you only need to file a TD1ON if you want to claim more than the basic personal amount, if your entitlements have changed, or if your payer asks for one. Skip it and your employer will simply apply the Ontario basic personal amount on its own.
How to fill out Form TD1ON
The TD1ON runs to ten lines, and every amount comes from the current year's version of the form, since Ontario indexes its credits annually:
- Line 1: the Ontario basic personal amount, claimed by virtually every employee working in the province.
- Line 2: the age amount if you will be 65 or older by December 31 and your net income is under the ceiling printed on the form.
- Line 3: the Ontario pension income amount for eligible pension or annuity income.
- Line 4: the disability amount if you qualify for the disability tax credit.
- Lines 5 and 6: the spouse or common-law partner amount and the amount for an eligible dependant, each reduced by the dependant's income as the worksheet describes.
- Line 7: the Ontario caregiver amount for infirm dependants age 18 or older, the province's combined replacement for the old caregiver credits.
- Lines 8 and 9: amounts transferred from your spouse or common-law partner or from a dependant.
- Line 10: total the claims, then sign and date the certification on page 2.
When to give it to your employer or payer
Submit the TD1ON to your employer or pension payer alongside your federal TD1 when you start, and again within seven days of any change in your entitlements. Like the federal form, it stays with the payer and is never mailed to the CRA.
If you hold two Ontario jobs at once, claim your provincial amounts with one employer only and check the more than one employer box on the second form, entering zero as the total claim.
Frequently asked questions
Yes, in most cases. The federal TD1 sets your federal tax deductions and the TD1ON sets the Ontario portion. Employers in Ontario normally ask new hires for both forms together.
Ontario discontinued its provincial tuition and education credits, so the current form has no tuition line. Students can still claim tuition on line 5 of the federal TD1 if they qualify.
For employment income the provincial form follows the province where you work, so you would complete the TD1ON along with the federal TD1. Your final tax is reconciled for your province of residence when you file your return.
It is a single provincial credit for supporting an infirm dependant age 18 or older, claimed on line 7 of the TD1ON. Ontario introduced it to replace its former caregiver and infirm dependant credits.
The amounts are printed on the current year's version of the form itself, available from the CRA. They change each year with indexing, so avoid reusing figures from an old copy.
