T1135 calculator at dated Bank of Canada rates.

List foreign holdings and their trades. See the highest total cost at any time in the year, the highest month-end cost and the year-end cost, in Canadian dollars. No account, and nothing you type leaves this page.

Enter one row per trade. A holding bought before the year and not traded since needs one Opening balance row with its total cost; pick CAD if that cost is already in Canadian dollars. Rates fill in from the date, and you can type over any of them. Use Save as CSV to keep your rows, because this page stores nothing.

What Form T1135 asks

Form T1135 is the Canada Revenue Agency's Foreign Income Verification Statement. A Canadian resident files it for any year in which the total cost amount of their specified foreign property was more than C$100,000 at any time. It is a reporting form, not a tax. Income from foreign property goes on the tax return whether or not the total ever reaches that line.

An individual does not file it for the year they first become a resident of Canada.

What counts

What does not

Cost, not market value

The test uses cost amount, which is generally the adjusted cost base. A position bought for C$60,000 and now worth C$150,000 still counts as C$60,000. Foreign purchases convert at the rate when they were bought, so later currency moves do not change the cost. Property received as a gift or inheritance, or owned on arrival in Canada, takes its fair market value at that time as its cost.

All property is added together. CRA's own example is shares costing C$75,000 plus a US bank account holding C$35,000: neither passes the line alone, but the C$110,000 total does.

"At any time" means any day of the year

The line applies at any time in the year, not just at year-end. If the total passed C$100,000 for part of the year, CRA says the form is due for that year even if everything was sold before December 31.

This calculator reads the total after every row, so a short peak shows up even when no month-end catches it. The built-in example does this on purpose: the total crosses C$100,000 for two weeks in March and sits below it at every month-end.

Part A or Part B

Above C$100,000 and under C$250,000 throughout the year, the form offers a choice between Part A, a simplified method with tick boxes, and Part B, the detailed tables. At C$250,000 or more at any time, Part B is the required method.

The month-end maximum

Part B asks for the maximum cost amount during the year. The form's instructions allow that figure to be based on the highest month-end cost, which is what the "highest month-end" column shows. Part A's country codes also rest on month-end cost, grouped by country.

Which exchange rate the form uses

AmountRate in the instructions
Cost of property boughtThe rate when it was purchased
Income receivedThe rate when received, or an average rate for the year if received throughout it
Maximum funds held in the yearThe average rate for the year
Funds at year-endThe rate at the end of the year
Maximum fair market value in the yearThe average rate for the year
Fair market value at year-endThe rate at the end of the year

The Bank of Canada rate lookup gives the rate on a date, the average for a year and the last rate of a year. For a foreign bank account, one simple approach here is an Opening balance row with the highest balance and the average rate typed in. A single row cannot follow a balance that moves through the year.

Holdings at a Canadian broker

Property held with a Canadian registered securities dealer or a Canadian trust company may be reported in total, country by country, in Part B's Category 7. That category uses fair market value rather than cost: the maximum during the year, which may be the highest month-end value, and the value at year-end. The C$100,000 test itself stays on cost. Whether a broker qualifies is something the broker can confirm.

This calculator works on cost, so it does not produce Category 7 market values.

Due date and penalties

The form is due on the due date of the income tax return, even if no return is otherwise required. CRA lists these penalties:

SituationPenalty
Filed late$25 a day for up to 100 days, minimum $100, maximum $2,500
Not filed, knowingly or through gross negligence$500 a month for up to 24 months, maximum $12,000, less penalties already charged
A formal demand to file is knowingly or grossly negligently ignored$1,000 a month for up to 24 months, maximum $24,000, less penalties already charged
Still outstanding after 24 months5% of the cost of the foreign property, less penalties already charged
False statement or omission, knowingly or through gross negligenceThe greater of $24,000 or 5% of the cost of the foreign property

CRA can also take three more years to reassess when foreign income was left off the return and the form was missing, late or wrong. Taxpayer relief and the Voluntary Disclosures Program may be open to people correcting past years.

What this calculator does not do
