TD1 FAQ
New employees and employees who have experienced a change in the type of tax deductions they are eligible for are asked to fill out Personal Tax Credits Return forms known as TD1s. Below are some of the most frequently asked questions about these forms.
- Am I required to complete a TD1 if I am being paid by Carleton University?
-
You are required to complete and submit a TD1 if you will be earning employment income from the university.
If an employee does not fill out a TD1 or TD1ON, Carleton will deduct taxes after allowing for the basic personal deduction amount only. This may mean that the employee ends up paying more taxes than they are required to at the source, so it is in the employee’s best interest to fill out this form.
- Can I put a non-Canadian address on my tax forms?
-
If you do not have a permanent address in Canada, you can use an international address.
- Do I need to provide proof of my date of birth or social insurance number (SIN)?
-
New employees do not need to provide proof of date of birth. Only temporary residents need to provide proof of SIN in the form of a letter of confirmation from Service Canada.
Be sure to indicate your date of birth and SIN on the Personal Tax Credit Return forms included in the employee documentation package.
- Do I need to submit new tax forms every year?
-
You only need to resubmit tax forms if you claimed anything more than the basic amount in the previous calendar year.
- How do I fill out the personal information section of the TD1 tax forms?
-
You must provide a valid off-campus permanent address to which a T4 can be sent for regulatory tax purposes. Otherwise, the T4 or T4A slip may not be sent to the correct address, or the slip will not be mailed at all until a valid address is provided.
Also, it is mandatory that you include your Social Insurance Number. If you do not have a SIN, you will need to get one from a Service Canada Office.
- How many TD1 forms do I have to fill out?
-
You have to complete a Federal TD1 for regulatory purposes as prescribed by Revenue Canada if you are earning employment income.
If you are only claiming the basic personal amount for deductions, you are not required to complete a Provincial TD1ON form.
If you are eligible for any other Ontario tax exemptions (e.g. tuition and education amounts, disability amount), you must complete a TD1ON form and submit it to the Payroll office if you want less taxes to be deducted from your pay.
