If you are considering permanently moving or accepting a short-term assignment to the US, there are a number of important tax considerations in both Canada and the US that should be addressed to ensure that that the move goes smoothly for tax purposes.

Residency

A resident of Canada is subject to Canadian income tax on global income. To avoid double taxation, Canada grants a foreign tax credit for foreign income taxes paid on income earned in that foreign country. The credit is subject to a limitation based on the Canadian tax on the foreign source income. A non-resident is subject to tax on income from Canadian sources, such as bonuses and deferred compensation previously earned in Canada.

Similarly, a resident of the US is subject to US income tax on global income. The US also grants a foreign tax credit for foreign income taxes paid on foreign source income. A non-resident of the US is subject to US federal income tax on income from US sources.

Since residence has a significant bearing on your global tax liability, it is important to understand what determines residence in both the US and Canada.

Canadian
An individual’s Canadian residency status for tax purposes is a question of fact and must be determined based on all of the particular facts and circumstances. It is not determined solely by the individual’s citizenship status (as may be the case in other jurisdictions) or physical location. An individual’s Canadian residence status will depend on the amount of residential ties he or she maintains in Canada. Examples of factors considered include the permanence and purpose of your stay in the country, whether your spouse and dependents accompany you, and the retention of personal property and/or economic and social ties (e.g., club memberships).

A person is also considered a deemed resident of Canada if the person is not otherwise a Canadian resident and he or she is present in Canada for 183 days or more in a tax year.

It is important to choose a date that the individual plans to terminate Canadian residence and establish a plan that will demonstrate the change of residence.

US
An individual will be considered a resident of the US if he or she meets one of two tests: the “green card” test or the “substantial presence” test. Under the “green card” test, an individual who is a lawful permanent resident (under immigration laws) will be considered a US resident. Resident status begins on the first day that the individual is physically present in the US as a lawful permanent resident.

Under the substantial presence test, an individual will establish US residence by being present in the US for 183 days or more over a three year period (an average of 122 days per year) computed under the following formula:

Number of days in the US in the current year
+ 1/3 number of days in the US in the prior year
+ 1/6 number of days in the US in the second prior year.

If the individual does not meet this test, he or she can elect to be a US resident in the first year of presence in the US if he or she is considered a resident under the substantial presence test in the following year and meets the following test: He or she is present in the US for 31 consecutive days and from the beginning of the 31-day period until the end of the year, is present in the US for at least 75 percent of the time. A consecutive day includes any day in which the person is present in the US for any part of a day. Consequently, if you fly from the US to Canada on Saturday morning and return to the US on Sunday evening, both Saturday and Sunday are considered US days and do not break the consecutive day period. The election will cause the individual to be a resident of the US on the first day of the 31 day period.

US-Canada Treaty
It is possible for an individual to be considered a resident of both Canada and the US at the same time. In these circumstances, the Canada-US tax treaty provides residency “tie-breaker” rules so that the individual will be considered a resident of only one country. Under the treaty, the following tests are applied, in order, until affirmative for one country and negative for the other:

  • Permanent home available
  • Personal and economic relations (centre of vital interests)
  • Habitual abode
  • Citizenship.

If residence has not been broken to one country under these tests, then the competent authorities of the two countries will make a determination.

Canadian Departure Tax

Individuals ceasing Canadian residency are deemed to have disposed of all their property immediately before ceasing residency for its fair market value at that time. This deemed disposition applies to most property and the resulting tax is commonly referred to as departure tax. Some property is excluded from being deemed disposed, including RRSPs, retirement plans, stock options and Canadian real estate.

Where the deemed disposition results in a taxable gain, the CRA currently permits the individual to either pay the tax or defer payment until the property is actually disposed of, provided that “adequate security” is given to CRA. No security is required for the first C$100,000 of gain. Additionally, should the fair market value of the assets be greater than C$25,000, CRA will require additional disclosure on your tax return.

US tax law taxes a resident individual on capital gains based on the difference between sales price and cost basis. Cost basis is based on historical cost. Consequently, a departure tax paid in Canada will not increase cost basis for US tax purposes. To avoid double taxation, Canadian tax law allows the individual to amend the Canadian departure-year tax return to claim a credit for the US taxes paid on selling an asset that was previously subject to Canadian departure tax. If the individual does not wish to postpone Canadian departure tax, he or she may consider selling the assets before establishing US residence and repurchasing the same assets or other assets. This will provide a new cost basis for US tax purposes, which will avoid the need to amend previously filed Canadian return.

Canadian Registered Retirement Savings Plan

Canadian Registered Retirement Savings Plans (RRSPs) are exempt from departure tax when an individual ceases Canadian residency and are not required to be withdrawn before departure. If an individual withdraws funds from an RRSP during non-residency, the distribution will be taxed at a rate of 25%. The rate can be reduced to 15% if paid as periodic pension payments to a resident of the US.

As a resident of the United States who maintains RRSPs, the individual needs to provide disclosure of accounts and balances to the Internal Revenue Service as part of the tax return. If proper elections are made, the United States will not tax income earned in an RRSP until funds are withdrawn.

Other US Tax Issues:

  • Purchase of a US home
    • Mortgage interest expense is deductible for federal income tax purposes for financing used to acquire or improve a primary or secondary residence. The mortgage limit for acquisition indebtedness is US$1 million. An individual can also obtain home equity financing of up to US$100,000. A person must be a US resident to claim this deduction. Prepaid finance charges (“points”) on a mortgage on the acquisition of a principal residence are deductible in the year paid, if incurred when a resident of the US. Otherwise, the points are deductible on a pro-rata basis of the life of the mortgage.
    • Property taxes are deductible if the individual is a US resident when paid.
    • Itemized deductions (including state income taxes, mortgage interest expense, property taxes, charitable contributions, etc) are reduced by 3% for each dollar earned in excess of a threshold amount.
    • The gain from the sale of a principal residence is excluded from US taxable income to the extent of US$250,000. If the individual is married filing jointly, the exclusion is US$500,000. The individual must have owned and used the home as a principal residence for at least two years out of the prior five years before the date of sale. There are certain exceptions to the two-year rule if one is required to move due to employment, health or unforeseen circumstances. If the exceptions apply, a pro-rata portion of the exclusion is allowed.
  • Canadian mutual funds
    • A US citizen or resident individual should avoid holding Canadian mutual funds outside a registered plan. Investments in foreign investment companies that meet the definition of a “passive foreign investment company” may result in adverse US tax consequences.

Short-term Assignments

As an alternative to a permanent move, individuals considering working in the US may consider a short-term assignment. Employees who are neither citizens nor residents of the US are subject to US taxation if they work even one day in the US unless they work for a non-US entity, the earnings allocated to US work does not exceed US$3,000, and they spend no more than 90 days in the US during the calendar year.

Canadian residents working in the US can take advantage of two provisions in the US-Canada tax treaty to avoid the US tax net:

  • If the Canadian employee earns less than US$10,000 from an employer in the US during a tax year, such income will be exempt from US income tax, or
  • If the Canadian employee is present in the US for no more than 183 days during a calendar year and the remuneration is not borne by a US employer nor by a taxable branch (permanent establishment) of a foreign employer, such income is exempt from US taxation, regardless of the amount of US source compensation.

Unfortunately, avoiding the US tax net may provide little benefit if the individual remains subject to the higher Canadian resident tax rates.

Totalization Agreement

Social security taxes payable in Canada are significantly lower than the social security taxes payable in the US on the same level of compensation. The Agreement on Social Security between the US and Canada (the “totalization agreement”) may allow Canadian employees temporarily transferred to the US to continue to be covered by the Canadian system and avoid the higher US contributions.

Employees working in the United States during 2006 are subject to US Social Security tax of 6.2% of the first US$94,200 of taxable compensation or a maximum of US$5,840.40. In addition, the employee is subject to Medicare tax of 1.45% of total compensation. The employer must pay a matching US Social Security tax and the Medicare tax. The wage base is adjusted upward each year. It is readily apparent that the US Social Security and Medicare taxes far exceed the CPP liability on equivalent income. The maximum CPP amount paid by an employee for 2006 is Cdn$1,910.70.

Under the totalization agreement, an employee sent by his or her Canadian employer to work in the US can continue to be covered by CPP for assignments up to 60 months. During that period, the employee would be exempt from US Social Security and Medicare tax on the same income. This can result in significant savings to both the employee and employer.

Generally, an employer cannot contribute to CPP on behalf of a non-resident employee. However, a Canadian employer can apply to cover non-resident employees located outside of Canada if the employment would be pensionable employment if it were in Canada and the employee was hired by the employer when the employee was present in and resident in Canada. The election will allow the employee to utilize the benefits of the totalization agreement and avoid the higher US contributions.

To establish an exemption from US social security and Medicare taxes, the Canadian employer should file CRA form CPT56 to request a Certificate of Coverage from the Department of National Revenue, Taxation in Ottawa. The approved certificate should be maintained by the US payroll agent. The Canadian employer should file a T4 each year indicating the CPP contributions. A footnote on the T4 should read “Filed for purposes of the Canada-US Totalization Agreement”.
