How to Access Old and Lost T4s and Other Tax Forms

What is a T4?

Also known as a Statement of Remuneration Paid, a T4 is a tax slip that lists how much employment income you've earned as a salaried employee. It also shows payroll deductions such as Canada Pension Plan (CPP) contributions, Employment Insurance (EI) premiums, Registered Retirement Savings Plan (RRSP) contributions, union dues, vacation pay, and more.

Employers are required by law to issue T4s for the preceding calendar year for current and former employees who have earned at least $500 or had deductions withheld. T4s must be issued by the end of February. This tax slip is essential for filing your taxes, so make sure you have yours before starting your tax return.

If you work as a freelancer or independent contractor, your clients may give you a T4A Statement of Pension, Retirement, Annuity, and Other Income. The T4A lists the dollar amount paid for each project or job and is used to help you calculate how much tax you owe. Unlike T4s, companies aren't required to issue T4As so you may not always receive them. Since you're running your own business, it's wise to keep track of your earnings instead of relying on T4As. You're also responsible for reporting all self-employment income on Form T2125 come tax time.

How do you recover old or lost T4s?

There are two ways to obtain old or misplaced T4s-your employer or the CRA.

You can ask your current or former employers for a copy of your T4 for the current tax year or previous years. Employers must keep paper and electronic records on file for six years.

You can also access your T4 online through the Canada Revenue Agency (CRA) through My Account for Individuals. This secure portal lets you view and manage your income tax and benefit information in a few clicks. It also stores original and amended tax slips issued by employers, administrators, and Service Canada for up to ten years.

Registering for an account involves two steps: filling in personal information and then inputting a security code which is mailed to your address or emailed to you once you call the CRA to verify your identity.

After logging in, you'll find a section titled “tax information slips” under related services. Select a tax year and T4 from the dropdown menus and then click next to see a list of tax slips for that tax year. Although there is no PDF download option, you can still print out the T4 as it appears on the page. If there are missing slips, you'll need to reach out to your employer. If the company has gone out of business or cannot issue you a T4, contact the CRA for assistance.

You can also ask the CRA to mail you a paper copy of your T4 by calling the individual enquiries line at 1-800-959-8281. The CRA agent will need to verify your identity first, so make sure you have your Social Insurance Number (SIN), name, date of birth, and address on hand.

Sometimes, the CRA asks questions related to previous tax returns. This may be challenging if you haven't filed for a long time. In this case, ask the agent if they can use other personal information on file to identify you.

How can you find old tax returns?

Besides tax slips, your CRA account also shows the last time you filed your taxes and stores copies of your old tax returns in the form of notices of assessment. After you file your taxes, the CRA issues a notice of assessment which means your tax return was received and processed.

The notice of assessment includes key information such as:

• tax year
• date the notice of assessment was issued
• how much you owe or get back as a refund
• total, net, and taxable income
• deductions and credits (e.g. tuition deductions, home office expenses)
• RRSP deduction limit for the upcoming tax year

Your notice of assessment is an important document, so it's a good idea to print it off from your CRA account and keep it with your tax records.
