We’re here to simplify this complex topic, giving you the straightforward, well-researched advice you need to confidently manage essential documents like the CRA tax forms and TD1 forms.

In this article, we explain everything HR teams and employers need to know about CRA tax forms and TD1 forms to ensure you stay compliant.

What CRA forms do I need as an employer?

Some of the CRA forms an employer will need when handling payroll may differ depending on which province the business is based in. However, some of the most common CRA forms include:

• TD1 forms, also known as Personal Tax Credits Return
• T1 forms, also known as the Income Tax and Benefit Return
• A T4 slip, officially known as the Statement of Remuneration Paid
• A T4A slip, also known as the Statement of Pension, Retirement, Annuity and Other Income

We’ll explore each CRA form in more detail below.

What is a TD1 form?

What is it? A TD1 form is a Personal Tax Credits Return that lets employers know how much income tax to deduct from employee payslips. Completing a TD1 form helps the Canada Revenue Agency process the correct tax deductions. This prevents employees from paying too much or too little tax.

Who should fill it out? Employers and payers must get completed TD1 tax forms from employees when they start work, or when they want to increase income tax deductions.

There are two types of TD1 forms:

• Federal TD1: Applies to the whole of Canada
• Provincial TD1: Applies specifically to each province or territory

Visit the Government of Canada TD1 forms page to find out more.

What is a T1 form?

What is it? The T1 is a taxpayer’s form, also known as the Income Tax and Benefit Return. It summarizes all income taxes paid to the CRA. This includes all the forms you complete for your income taxes and the information needed to file.

Who should fill it out? Anyone who owes taxes needs to complete a T1. Business owners must complete the T1 business form. Corporations must complete the T2 Corporation Income Tax Return, unless located in Quebec or Alberta. In which case, you need to file a separate provincial corporate return.

T4 slip

What is it? The T4 identifies the total remuneration an employer pays an employee over the year.

Who should fill it out? Resident and non-resident employers who paid employees employment income, commissions, taxable allowances and benefits, fishing income or other remuneration must issue a T4 slip if:

• You deducted CPP / QPP, EI, PPIP or income tax from remuneration paid to the employee
• If the remuneration you paid to the employee does not fall under the exception list and the total of all remuneration paid in the year exceeds $500

Visit the Government of Canada T4 slip Information for employers page for details on how to complete T4 slip.

T4A slip

What is it? The T4A slip reports different types of income paid during the year that don't directly relate to an employee’s regular income. This may include self-employed commissions and Registered Education Savings Plan (RESP) payments.

Who should fill it out? Employers must issue a T4A slip if:

• You deducted tax from any payment
• If the payment does not fall under the exceptions list and the total of all payments in the year exceeds $500

What to report on a T4A slip

• Pension or superannuation
• Lump-sum payments
• Self-employed commissions
• Annuities
• Research grants

These are just a few examples of what to report on a T4A slip. For a comprehensive list, please visit the Government of Canada T4A slip Information for payers page.

Other forms

Other Canada Revenue Agency (CRA) forms employers may need to use include:

• TRA-RCA slip: Identifies the amounts distributed during the year to a person from a retirement compensation arrangement. This could be as a beneficiary or if they sold an interest in it. The TRA-RCA slip also details the income tax deducted from the amounts distributed.
• T4A-NR slip: Identifies payments made to non-resident individuals, partners, or corporations during the year for services carried out in Canada that do not fall under employment situations.
• T4PS slip: Identifies the amounts allocated to an employee who is a beneficiary of an employee’s profit-sharing plan. This could be contingently or absolutely.
