For most individuals, their
principal residence is their single most important asset. In Canada, when an individual sells their
principal residence the gain on the sale is exempt from capital gains tax in
most instances. A taxpayer must designate the property as their principal
residence when they file their Canadian personal income tax return. This is one
of the biggest gifts to individuals in the Income Tax Act.
Canadian residents who are also U.S.
persons will also be subject to the U.S. rules surrounding the sale of a
principal residence. These rules are
quite different and for many taxpayers, given the increase in value of Canadian
real estate, may give rise to an unpleasant surprise. For U.S. purposes, only the first $250,000 USD
of gain on the sale of a principal residence is exempt from capital gains
tax. For a married couple this exemption
is $500,000 USD, but only if both taxpayers are U.S. persons. Amounts above the exemption will be subject
to capital gains tax.
To calculate the gain for U.S.
purposes, the proceeds from the sale are translated into U.S. dollars using the
spot rate on the date of sale and the cost base is translated into U.S. dollars
using the spot rate on the date of purchase. Using this method, any increase or decrease in
the value of the U.S. dollar versus the Canadian dollar is also included with
In addition to the capital gains
tax, U.S. persons who hold a Canadian mortgage on their principal residence may
also be subject to tax when that mortgage is discharged. This tax comes into play when the value of
the Canadian dollar has decreased against the U.S. dollar since the mortgage
was obtained. This tax is best explained
with an example:
Let’s take the example of Sam, who
is a U.S. citizen resident in Canada. Sam
purchased his principal residence in Canada and obtained a mortgage of $100,000
CAD when the Canadian dollar and U.S. dollar were at par (1 CAD = 1 USD). Therefore his mortgage was worth $100,000 CAD
and $100,000 USD. He subsequently sold
the property. At the time of disposition
(and assuming he did not pay off any of the mortgage principal) the value of
the Canadian dollar had decreased to 75 cents U.S. (1 CAD = .75 USD). At the time of discharge, his $100,000 CAD
mortgage is now worth $75,000 USD.
Because it takes fewer U.S. dollars to pay back his original obligation,
the U.S. views this $25,000 foreign exchange difference as a taxable gain to
Sam for U.S. income tax purposes.
This, of course, is a simplified
example to illustrate the concept of a Foreign Mortgage Gain. The example does not take into account the
principal on the mortgage that has been repaid by Sam, which is considered in
an actual Foreign Mortgage Gain calculation.
The Foreign Mortgage Gain on a principal residence is considered foreign-source ordinary income and can be offset with foreign tax credits. The gain is allocated to the general foreign income basket, so if a taxpayer has sufficient accumulated excess foreign tax credits in this basket to offset the Foreign Mortgage Gain then no tax may be payable. A Foreign Mortgage Loss on a principal residence is considered a personal loss and is disallowed.
While technically a Foreign
Mortgage Gain or Loss should be calculated on each mortgage payment made, the
Internal Revenue Code states that a personal foreign exchange gain of $200 or
less does not have to be reported.
Therefore, in practice the Foreign Mortgage Gain calculations are not
With the substantial rise in
real estate values in most Canadian cities, we have seen many U.S. persons pay
U.S. tax on the sale of their principal residence when they had assumed the
sale would be tax-free. It’s important
that U.S. persons become familiar with these rules and plan for any potential
U.S. tax on the sale of their home.
