☎️ Get HelpWhy You Should File Late Tax Returns
There are several important reasons to file overdue tax returns as soon as possible.
You May Be Owed a Refund
If taxes were withheld from your employment or other income and you never filed a return, you may still be entitled to a refund.
Government Benefits Require Tax Returns
Benefits such as the GST/HST Credit, Canada Child Benefit (CCB), Ontario Trillium Benefit, and other federal or provincial programs generally require an annual income tax return.
Penalties and Interest Continue to Grow
If you owe taxes, late-filing penalties and interest continue to accumulate until the balance is paid.
The CRA May Request Your Returns
The CRA can contact taxpayers with outstanding filing obligations and require them to submit overdue returns.
An accountant for taxes can help estimate any penalties and interest before you file.
How Far Back Can You File?
If You Are Owed a Refund
The CRA generally allows refunds only for returns filed within 10 years of the applicable tax year. Returns older than 10 years may still be accepted, but a refund is generally not available.
If You Owe Taxes
There is generally no time limit for filing a return with taxes owing. Interest and penalties continue to accrue from the original filing and payment deadlines until the balance is resolved.
How to File Previous Years’ Taxes: Step by Step
Step 1: Get the Correct Tax Forms
Use the tax package for the specific year you are filing. Tax rates, deductions, and credits change each year, so current-year forms cannot be used for prior-year returns.
Step 2: Collect Your Income Slips
Gather all applicable tax slips, including T4, T5, T4A, and other income documents. If you no longer have them, many can be accessed through CRA My Account.
Step 3: Prepare the Return
Use CRA-certified software that supports prior-year returns or work with a qualified tax preparer to complete the correct return for each tax year.
Step 4: Submit Your Return
Depending on the tax year, eligible returns may be submitted electronically if supported by CRA’s current NETFILE service, while older returns may need to be mailed. Follow the filing method available for the year you are submitting.
Step 5: Wait for CRA Processing
Processing times vary depending on the tax year and filing method. You can monitor the status of your return through CRA My Account once it has been received.
Tax and accounting services can help ensure each year’s return is prepared using the correct forms and tax rules.
What Penalties Apply for Late Filing?
If you owe taxes and file late, the CRA may charge:
- A late-filing penalty of 5% of the balance owing.
- An additional 1% of the balance owing for each full month the return is late, up to 12 months.
- Higher penalties may apply for repeated late filing.
- Daily compound interest on unpaid balances from the original payment due date.
If you are entitled to a refund, there is generally no late-filing penalty. However, filing within the applicable time limits is important if you wish to receive your refund.
Income tax preparation near me services can help calculate penalties and prepare multiple outstanding returns.
The Voluntary Disclosures Program (VDP)
If you have several years of unfiled returns and are concerned about penalties, the CRA’s Voluntary Disclosures Program (VDP) may provide relief in certain situations.
To qualify, your disclosure generally must:
- Be voluntary before the CRA contacts you.
- Be complete and include all relevant information.
- Involve information that could result in penalties or taxes owing.
- Include payment arrangements where applicable.
The CRA reviews each application individually to determine eligibility for relief.
A tax accountant near me can help determine whether the Voluntary Disclosures Program may be appropriate for your circumstances.
