As a T4 employee engaged with Procom, it's important to keep your federal and provincial/territorial TD1 forms up to date. According to the Canada Revenue Agency (CRA), you must submit a new TD1 within 7 days of any life change that affects your personal tax credits, such as marriage, a new dependant, moving provinces, or eligibility for age or disability credits.

How to update your TD1 form

1. Submit a ticket

   Use the button below to initiate a request with the CS Helpdesk.

   

2. Receive the TD1 package

   We will send you federal and provincial TD1 forms via the contractor portal.

3. Complete and submit the forms

   If you have credits to include in the first section above the basic personal amount, you may choose to use CRA worksheets (TD1‑WS) to calculate your total credit amounts accurately.

   When completing the form, please note the following:

   1. More than one employer or payer at the same time:
      1. If this applies to you, you must check this box. No tax CREDITS will be applied to your payroll deductions with Procom.
   2. Total income for the year will be less than the total claim amount:
      • This option means no tax will be deducted from your payments.
      • Important Caution: If you check this box and later earn more than expected, you may end up owing income tax at year-end. We've seen cases where contractors mistakenly selected this, resulting in under-deductions and unexpected tax bills.
      • Procom cannot determine whether you qualify for this exemption and is not responsible for any tax consequences. If you are unsure how to complete these sections or whether they apply to your situation, we strongly recommend consulting with a tax professional.

4. Payroll update

   We will update our system and apply the changes to your next pay period.

Why prompt updates matter

• Accurate tax withholdings: Claiming new credits (like a dependant) without updating your TD1 may cause over‑deduction of taxes, meaning less take‑home pay now and a larger refund later. Conversely, failing to update when credits decrease could result in under‑deduction, potentially leaving a balance owing at tax time.

• CRA compliance: Staying within the CRA’s 7‑day rule avoids administrative penalties.

Typical situations that require an update

• Personal life events: marriage, separation, childbirth.

• Credits eligibility: turning 65+, caregiver or disability credits.

• Work changes: taking a second job.

• Geographic move: If you’re moving to a different province, let Procom know right away so we can update your profile. A move may also affect other parts of your engagement with us, so advance notice helps avoid delays or issues.

What if you don’t update?

If a new TD1 isn’t submitted within 7 days:

• You may see excess tax withheld on your T4 and get a refund, or end up owing taxes and interest at year-end.

• CRA may impose penalties ($100 minimum, plus $25 daily up to $2,500) for late TD1 submission.

Final summary

Updating your TD1 within 7 days of changes ensures proper withholding and CRA compliance. Procom streamlines the process- you submit a ticket, complete and submit forms on the contractor portal, and we update your payroll profile- but we cannot assist with form content. If you need support beyond filing the forms (e.g., understanding credits or calculations), please reach out to a tax professional or visit the CRA's TD1 page for guidance. We’re here to facilitate the process, but not to advise on how you fill out the TD1.
