The $23,600 Foreign Income Mistake Newcomers Make

▶

A newcomer who arrives in Canada with $150,000 CAD in overseas savings and “forgets” to report the account can be hit with more than $7,500 CAD in penalties and interest within a few years once the CRA discovers it, between T1135 late‑filing penalties of up to $2,500 CAD per year and income‑underreporting penalties of up to 50% of the tax owed on that foreign interest.

The number that matters

5% — penalty on foreign assets after 24+ months of gross‑negligence non‑filing If a taxpayer knowingly or with gross negligence fails to file required foreign reporting forms for more than 24 months, the CRA can impose an additional penalty of 5% of the cost or fair market value of the foreign property or amounts transferred, on top of per‑day and per‑month penalties.

• Suffix: %
• Measures: Extra punitive penalty on the value of foreign property when foreign reporting has been knowingly ignored for over 2 years
• Source & year: Canada Revenue Agency (CRA) “Questions and answers about penalties – Foreign reporting” and Fasken Tax Bulletin, 2014–ongoing CRA administrative policy

How it quietly costs you

Mechanism: World‑wide income + foreign asset reporting, even for newcomers

• Once you become a Canadian resident for tax purposes, you must report all income earned anywhere in the world, including employment, rental, investment, business income, pensions and capital gains from every country, converted to Canadian dollars.
• Canadian resident taxpayers must also report all income from foreign property, regardless of amount; if the cost amount of specified foreign property exceeds $100,000 CAD at any time in the year, they must file Form T1135 – Foreign Income Verification Statement in addition to their tax return.
• “Specified foreign property” includes foreign bank accounts, non‑Canadian stocks and bonds (held outside registered plans), foreign rental real estate, interests in foreign corporations, and certain foreign trusts.

Impact: Automatic T1135 penalties, even if you owe little or no tax

For T1135 and other foreign‑reporting forms, CRA’s penalty regime is largely automatic once a form is required but not filed on time:

• Basic late‑filing penalty: the greater of $100 CAD or $25 CAD per day, up to a maximum of $2,500 CAD per year for each foreign‑reporting information return (including T1135) filed late.
• If the failure to file is knowingly or under circumstances amounting to gross negligence, CRA can assess $500 CAD per month, up to $12,000 CAD per year, less any basic penalties already charged.
• If CRA has issued a formal demand to file and the person still knowingly or with gross negligence fails to file, the penalty increases to $1,000 CAD per month, up to $24,000 CAD per year, again less any earlier penalties.
• After more than 24 months of gross‑negligence non‑filing, an additional penalty can apply: 5% of the cost of foreign property, foreign affiliate shares or indebtedness, or 5% of the fair market value of property transferred/loaned to a non‑resident trust, imposed once for that year.

Old vs. better comparison (T1135 penalty exposure)

• “Old” behaviour (ignoring T1135):
• Newcomer holds $150,000 CAD in specified foreign property and fails to file T1135 for 3 years.
• Basic penalties alone could reach $2,500 CAD per year, totalling $7,500 CAD; if CRA views it as gross negligence and issues a demand, penalties could escalate towards $12,000–$24,000 CAD per year, plus potential 5% of $150,000 = $7,500 CAD once the failure exceeds 24 months.
• “Better” behaviour (file correctly):
• The same newcomer files T1135 and reports foreign income each year.
• T1135 filing itself carries no fee; the “cost” is the tax correctly payable on foreign income, often reduced by foreign tax credits claimed on Form T2209 so the same income is not taxed twice.

The second, compounding trap

Mechanism: CRA penalties for unreported foreign income + extended audit window

Beyond information‑return penalties, hiding foreign income itself triggers separate reassessments and penalties:

• CRA explicitly warns that failing to report foreign income leads to reassessments, penalties, interest, and foreign income audits, and in serious cases, gross negligence penalties and potential criminal tax‑evasion prosecution.
• For failing to report an amount of $500 CAD or more of income on the 2022–2025 returns (including foreign income), a repeated‑failure penalty can apply each year: the lesser of
• 10% of the unreported amount (federal + provincial/territorial combined), or
• 50% of the difference between the understated tax/overstated credits and the tax withheld from that unreported income.
• If CRA finds that a taxpayer knowingly made a false statement or omission (gross negligence), another penalty can apply for 2025 and later: the greater of
• $100 CAD, or
• 50% of the understated tax or overstated credits related to the false statement or omission.
• Tax practitioners note that, as a general pattern, CRA penalties on unreported income can be around 10% of the unreported income and may reach 50% of the tax owed when gross negligence is assessed.
• Recent rules allow CRA to extend the normal reassessment period from 3 years to 6 years for individuals who fail to report income from foreign property and either did not file T1135, filed it late, or filed it inaccurately.

Impact: Concrete long‑run costs on hidden foreign income

Consider a newcomer who becomes resident and leaves a $150,000 CAD foreign savings account abroad:

• Suppose the account earns 3% interest per year, or $4,500 CAD annually, and the newcomer fails to report this interest for 3 consecutive years.
• Unreported foreign income over 3 years: $4,500 × 3 = $13,500 CAD.
• Assume marginal Canadian tax rate of 30%, so tax properly due on that income would be $4,050 CAD over 3 years.
• If CRA reassesses and applies the 10% of unreported income penalty noted by tax practitioners, that could mean about $1,350 CAD in penalties (10% of $13,500 CAD) on top of the $4,050 CAD tax.
• If CRA instead applies the higher “50% of understated tax” gross negligence penalty, this could add around $2,025 CAD (50% of $4,050 CAD) in penalties.
• Interest accrues on both unpaid tax and penalties from the original due date until paid; while exact amounts depend on CRA’s quarterly prescribed interest rates, the direction is clear: the longer foreign income remains hidden, the more tax, penalties and interest accumulate.

Over 6 years (the extended reassessment window for foreign income issues), repeating the same behaviour could multiply these costs:

• Six years of unreported $4,500 CAD income = $27,000 CAD total unreported foreign income.
• At 30% tax, that is $8,100 CAD of unpaid tax.
• A 10% penalty on unreported income would be $2,700 CAD; a 50% penalty on understated tax could be $4,050 CAD.
• Combined with T1135 penalties from Problem 1, total CRA bills for a newcomer could easily exceed five figures even when the underlying foreign income is modest relative to their overall finances.

What this looks like in practice

Persona

• Name: Ana
• Age: 34
• Status: Immigrated to Canada 3 years ago, now a Canadian tax resident
• Job: Software developer in Toronto
• Gross employment income in Canada: $110,000 CAD per year
• Foreign situation: Savings account in her home country with $120,000 CAD deposited before moving; earns 3% interest per year (about $3,600 CAD annually)
• Account type: Non‑registered foreign bank deposit; no RRSP/TFSA involvement
• Years to retirement: 31 years (target age 65)

Ana assumed she only had to report her Canadian salary and that foreign savings “don’t count” until she brings the money to Canada. After a CRA review triggered by international data‑sharing, she learns three painful facts.

Discovery 1 — She was supposed to report all foreign income from day one

• CRA’s rules state that once you are a Canadian resident, you must report all world‑wide income, including foreign bank interest, each year in Canadian dollars.
• Ana’s foreign account earned $3,600 CAD per year, totalling $10,800 CAD over the last 3 years, none of which she reported.
• At an estimated 30% marginal tax rate, she now faces about $3,240 CAD in back taxes on this foreign interest alone ($10,800 × 30% = $3,240 CAD), plus applicable interest.
• Benchmark comparison: if she had properly reported and claimed foreign tax credits (e.g., via Form T2209), she could have reduced or eliminated double taxation; foreign tax credits are specifically designed to avoid taxing the same foreign income twice.

Discovery 2 — Her foreign savings triggered a T1135 filing requirement she ignored

• CRA clearly states that if the cost amount of specified foreign property exceeds $100,000 CAD at any time during the year, the taxpayer must file Form T1135 with their tax return.
• Ana’s $120,000 CAD foreign savings exceeded the $100,000 CAD threshold from the day she became resident, so she should have filed T1135 for each of the last 3 years.
• She did not file T1135 at all. CRA assesses the basic late‑filing penalty of $25 CAD per day, capped at $2,500 CAD per year.
• Over 3 years, that is $2,500 × 3 = $7,500 CAD in T1135 penalties, even before considering any gross‑negligence escalations.
• Comparison: if Ana had filed T1135 on time each year, the cost of compliance would have been $0 in penalties, with the only financial impact being the correct tax on her reported foreign interest and any minor administrative effort.

Discovery 3 — CRA can penalize her more and audit her for up to 6 years

• Because Ana both failed to report foreign income and failed to file T1135, CRA can extend her reassessment period from 3 years to 6 years, meaning they can go back and re‑audit her returns for the entire 6‑year window once she became resident.
• CRA’s penalty regime allows them to impose up to 50% of the understated tax where they determine a false statement or omission was made knowingly or with gross negligence.
• If CRA views Ana’s behaviour as more than just a careless mistake, she could face an additional $1,620 CAD (50% of her $3,240 CAD understated tax on the 3 years of foreign interest) or more, depending on how many years they reassess.
• Compared to the scenario where she voluntarily discloses past errors through CRA’s Voluntary Disclosures Program, under which penalties and prosecution can potentially be waived or reduced, Ana is now facing significantly higher, avoidable costs for staying silent.

The full cost of doing nothing

Using Ana’s situation as a concrete model:

Assumptions

• Foreign savings: $120,000 CAD held abroad continuously for 6 years as a Canadian tax resident.
• Interest rate: 3% per year, all unreported (foreign interest income).
• Marginal Canadian tax rate: 30% on foreign interest.
• T1135 required every year (foreign property > $100,000 CAD).
• CRA eventually reassesses after 6 years and applies:
• Basic T1135 late‑filing penalties (no gross‑negligence escalation).
• A conservative income‑underreporting penalty equivalent to 10% of unreported income, reflecting typical CRA practice described by tax experts.

Modelled costs over 6 years of inaction

1. Unreported foreign income

• Annual interest: $120,000 × 3% = $3,600 CAD
• Six‑year total: $3,600 × 6 = $21,600 CAD unreported foreign income.

2. Back taxes owed

• Tax on foreign interest: $21,600 × 30% = $6,480 CAD in unpaid tax.

3. Income penalties (approximate)

• 10% of unreported income: $21,600 × 10% = $2,160 CAD penalty.
• If CRA applied the harsher 50% of understated tax rule instead, this could reach 50% × $6,480 = $3,240 CAD.

4. T1135 penalties

• Basic late‑filing penalties: up to $2,500 CAD per year, for 6 years: $2,500 × 6 = $15,000 CAD.

Headline combined number (conservative 10% penalty case)

• Back taxes: $6,480 CAD
• Income‑underreporting penalties: $2,160 CAD
• T1135 late‑filing penalties: $15,000 CAD

Total CRA bill after 6 years: $23,640 CAD in taxes and penalties, not including interest that would further increase the amount.

If gross negligence is found and a 5% property‑value penalty is applied after 24+ months of non‑filing, Ana could face an additional 5% × $120,000 = $6,000 CAD, pushing her total exposure near $29,640 CAD, again before interest.

What to do about it

Move 1 — Audit your world‑wide income and fix past gaps

1. Action: Review and list all foreign income since becoming a Canadian tax resident, then correct any omissions.
2. Tool/portal:

• CRA My Account – review past filed returns, T‑slips and notices of assessment to see what income was reported.
• Use CRA’s guidance on “False reporting or repeated failure to report income” and foreign income rules to identify missing amounts.

3. Steps:

• Log in to CRA My Account and download your last 3–6 years of returns and notices of assessment.
• Make a separate list of all foreign income sources (bank interest, dividends, rent, pensions, business income) and convert each year’s amounts to Canadian dollars using appropriate exchange rates.
• If you discover unreported foreign income of $500 CAD or more in any year, consult a tax professional about amending returns and/or filing under the Voluntary Disclosures Program before CRA contacts you, which can reduce or avoid penalties.

4. Benchmark (“good” looks like):

• Every year’s return shows all foreign income reported in CAD, with no gaps of $500 CAD or more, eliminating exposure to repeated‑failure and false‑statement penalties.

Move 2 — Check whether you must file Form T1135

1. Action: Determine whether your specified foreign property ever exceeded $100,000 CAD cost in any year and file T1135 where required.
2. Tool/portal:

• CRA Form T1135 guidance and instructions – CRA’s official definition of “specified foreign property” and the $100,000 CAD reporting threshold.
• CRA My Account – confirm whether T1135 was filed for prior years.

3. Steps:

• List all non‑Canadian assets (bank accounts, non‑Canadian securities held outside RRSP/TFSA, foreign rental properties, interests in foreign corporations and certain trusts) and calculate their cost amount in CAD for each year since becoming resident.
• For any year where the total cost amount exceeded $100,000 CAD, check in CRA My Account whether a T1135 was filed; if not, you are exposed to late‑filing penalties of $25 CAD per day up to $2,500 CAD per year.
• File missing T1135 forms as soon as possible, and consider voluntary disclosure if the delay is substantial or appears knowing/grossly negligent.

4. Benchmark (“good” looks like):

• For every year your foreign assets exceeded $100,000 CAD, a T1135 was filed on time, with no late‑filing penalties and no risk of the 5% property‑value penalty.

Move 3 — Claim foreign tax credits to avoid double taxation

1. Action: Make sure you are claiming foreign tax credits for tax already paid overseas
