The short answer is: you can face serious penalties, interest, and even legal action. The Canada Revenue Agency (CRA) requires residents and certain non-residents to report all worldwide income, including earnings from jobs, investments, and property abroad.
I once had a friend who worked remotely for a foreign company and didn’t report her income to the CRA. She thought it was harmless because she earned nothing in Canada that year. When CRA discovered the unreported income, she had to pay back taxes, penalties, and interest—an experience she describes as stressful and costly.
In this article, I’ll explain what happens if you don’t report foreign income, common mistakes like forgetting to file T1135, how CRA tracks unreported income, penalties, and strategies to stay compliant. Understanding these rules will save you from trouble and unnecessary financial stress.

What Happens if You Don’t Report Foreign Income in Canada?
Failing to report foreign income in Canada can trigger penalties, interest, and reassessment by CRA. Canada’s tax system is based on voluntary compliance, but CRA has extensive tools to identify unreported income.
If you deliberately hide foreign income, CRA may consider it tax evasion, which is a criminal offense. Consequences can include:
Payment of back taxes
Penalties up to 50% of the unreported amount
Interest charges on unpaid taxes
Possible prosecution in extreme cases
Even if the omission was accidental, you can still face penalties, though CRA may reduce or waive them if you voluntarily disclose your mistake.
It’s important to understand that foreign income includes wages, dividends, rental income, capital gains, and even cryptocurrency. CRA requires disclosure through forms such as T1 (annual income tax return) and T1135 (Foreign Income Verification Statement).
Not reporting income can also impact eligibility for benefits like the Canada Child Benefit (CCB) and GST/HST credits, as CRA calculates these based on reported income.
What Happens if You Forget to File T1135?
The T1135 form is used to report foreign assets valued over CAD 100,000. Forgetting to file it can lead to severe consequences.
CRA imposes:
Penalties starting at $25 per day, up to $2,500 per year, for late filing.
If the failure is deemed gross negligence, the penalty can increase to 5% of the foreign assets’ value.
For example, if you own foreign stocks worth $200,000 and fail to file T1135, the penalty could be $10,000.
Even if you didn’t earn income from the foreign assets, CRA still requires reporting. Filing T1135 accurately ensures compliance and prevents CRA from suspecting you of tax evasion.
Voluntary disclosure before CRA contacts you can reduce penalties significantly, so if you forgot, it’s better to act quickly.
What Happens if You Forgot to Declare Income?
If you forget to declare foreign income, CRA may audit your return and reassess taxes owed. Penalties depend on whether the omission was:
Inadvertent: CRA may charge interest and minor penalties.
Gross negligence or intentional: Higher penalties, potential prosecution, or garnishment.
You can correct mistakes by filing a T1 Adjustment Request or through CRA’s Voluntary Disclosures Program (VDP). Using VDP can reduce penalties and avoid criminal charges.
Common types of income people forget to report include: foreign salaries, dividends, rental income, and cryptocurrency earnings. Keeping detailed financial records is critical to avoid costly mistakes.
What is the Most Common Mistake Made on Taxes?
The most frequent tax mistakes for Canadians abroad include:
Forgetting to report foreign income
Missing T1135 filings
Claiming ineligible deductions
Miscalculating capital gains
Overlooking foreign tax credits
These errors often trigger audits or reassessments. The key is accurate reporting and maintaining documentation. Using a qualified accountant familiar with cross-border tax rules can prevent these mistakes.
Are Taxes Forgiven After 10 Years in Canada?
No, Canada does not forgive taxes simply because time passes. CRA has a general reassessment period of 3 years after the original filing. However, for fraud or misrepresentation, CRA can reassess at any time.
This means that even if you forgot foreign income many years ago, CRA can still pursue taxes if it suspects fraud or intentional concealment. There is no statute of limitations for serious tax evasion.
How Does CRA Find Unreported Income?
CRA uses multiple methods to detect unreported foreign income:
Information sharing agreements with other countries
Data matching with banks and financial institutions
Cross-referencing employer and investment statements
Audits and voluntary disclosures
In addition, third-party reporting and international agreements like the Common Reporting Standard (CRS) allow CRA to track foreign bank accounts and investments automatically.
What is the 3-Year Rule for CRA?
The 3-year rule refers to CRA’s standard reassessment period. Typically, CRA can reassess your tax returns for up to 3 years after the original filing deadline.
Exceptions include:
Fraud, misrepresentation, or gross negligence: CRA can reassess at any time
Foreign reporting omissions: CRA can use information sharing to extend review periods
This rule emphasizes the importance of keeping accurate tax records for at least 6 years in case CRA requests information.
Does the CRA Check Every Tax Return?
No, CRA does not check every return, but it uses risk assessment and automated tools to flag:
High-value foreign assets
Unusual deductions
Missing T1135 forms
Large discrepancies between income and lifestyle
If flagged, CRA may request additional documentation or initiate an audit.
Does CRA Monitor Bank Accounts?
Yes, CRA monitors Canadian bank accounts, and through international agreements, it can access foreign account information. Banks report interest income, and under the CRS, foreign institutions share account information with CRA.
Failing to report foreign accounts or income can trigger penalties and investigations.
What is the Penalty for Not Filing T1135?
Penalties for not filing T1135 depend on the nature of the failure:
Late filing: $25 per day, up to $2,500 per year
Gross negligence or intentional non-compliance: 5% of the value of foreign assets
Repeat offenses or high-value omissions can lead to criminal prosecution
Timely voluntary filing can significantly reduce penalties.
How Does the IRS Find Out About Foreign Income?
For Canadians with U.S. ties, the IRS receives foreign income information through:
FATCA (Foreign Account Tax Compliance Act) reporting
Exchange of information agreements with CRA and foreign banks
Employer and investment reporting
Non-compliance with IRS rules can result in fines, interest, and penalties similar to CRA enforcement.
Conclusion
Not declaring foreign income in Canada can lead to penalties, interest, audits, and legal consequences. Here are the key points:
Report all foreign income, including wages, dividends, rental income, and cryptocurrency
File T1135 for foreign assets over CAD 100,000
CRA can reassess and track unreported income through audits, information sharing, and bank monitoring
Penalties increase significantly for intentional omissions or gross negligence
Use voluntary disclosure programs to reduce penalties
Failing to report foreign income is not worth the risk. Stay compliant and consult a tax professional if needed.
