Moving across the border involves more than just packing boxes and hiring movers. The year an individual enters or departs the U.S. often brings a complex web of tax obligations. If you are navigating this transition, you likely have several options for filing your U.S. tax return.

Working with a specialist cross border tax accountant in Toronto who understands the “ins and outs” of these options is essential to maximizing your benefits and avoiding costly errors. Whether you are dealing with American taxes in Canada or moving south, the right strategy makes a significant difference.

The three primary ways individuals file a U.S. tax return are as a:

1. Resident alien
2. Non-resident alien
3. Dual-status alien (utilizing a dual-status tax return)

What is a U.S. Dual-Status Tax Return?

Navigating US tax in Toronto requires understanding how residency rules differ between the two nations. Under Canadian tax rules, individuals often file a part-year return the year they become a Canadian resident. However, U.S. tax rules function differently.

While a U.S. corporate taxpayer may file a part-year return, individuals are generally not permitted to do this. What does this mean for you? Even when you are resident in the U.S. for only part of the tax year, you generally file a tax return that covers the full calendar year.

Because of this, in the year an individual enters or leaves the U.S., they are usually classified as both resident aliens and non-resident aliens on the same return. Hence the name: “dual-status.” It is essentially a return in which an individual is treated as a resident for part of the year and a non-resident for the remainder. As a US and Canada tax accountant, we often see clients confused by this hybrid status, but it provides specific opportunities for tax planning.

Filing Options: Resident vs. Non-Resident

To understand why a dual-status return might be beneficial—or mandatory—it helps to understand the two base statuses. Any experienced Canada US tax advisor will highlight the stark differences in deductions and reporting requirements.

Filing as a Resident Alien

Residents report their worldwide income on the traditional Form 1040. Much like U.S. citizens, resident aliens have access to many standard credits and deductions, with only a few exceptions.

Filing as a Non-Resident Alien

In contrast, U.S. non-resident aliens report only US-sourced income on Form 1040-NR. This form is far more restrictive. On a 1040-NR:

• Neither the “head of household” nor “married filing joint” statuses are available.
• Under the Tax Cuts and Jobs Act (TCJA) of 2017, personal exemptions are suspended.
• While the standard deduction has increased for residents, it is not available to those filing Form 1040-NR.
• Only limited itemized deductions can be taken.

With all these restrictions, filing as a non-resident often results in a bigger financial impact. This is where a cross border tax accountant Toronto can help determine if a dual-status filing or specific election can lower your liability.

How a Dual-Status Tax Return Works

Fortunately, there are several elections available when filing a dual-status tax return. Your status as an “inbound” or “outbound” alien depends on how your residency changes during the tax year.

• Inbound Aliens: These are individuals moving into the U.S. Because their status at the end of the year is “resident,” the resident Form 1040 return is filed as the primary form.
• Outbound Aliens: These are individuals departing the U.S. with a non-resident status at the end of the tax year. They file a non-resident Form 1040-NR as the primary form.

Residency Tests: Are You a Resident or Non-Resident?

Before filing, you must determine your exact status. A Canadian American accountant will typically look at two specific tests to determine if you are a resident alien, non-resident alien, or both:

1. The Green Card Test
This is straightforward. If you hold a green card at any point during the tax year, you meet the test unless it is abandoned, surrendered, or administratively taken away. It is vital to remember that simply allowing a green card to expire does not relieve you of the requirement to file a U.S. tax return.

2. The Substantial Presence Test
This is a math equation used by every cross border tax professional. The test is met if your days of physical presence in the U.S. are:

• At least 31 days in the current year; AND
• 183 days in a three-year period computed as:
• • Current year days; plus
  • 1/3rd of last year’s days; plus
  • 1/6th of the days from two years ago.

Important Note: There are special rules regarding what constitutes a “day.” For example, days spent in the U.S. by a Canadian who commutes daily for work may be exempt from the count. If you need to override the substantial presence test, your US Canada tax accountant will ensure you include Form 8840, Closer Connection Exception Statement for Aliens.

Dual-Status Elections to Optimize Your Return

This is where expert advice from a cross border tax Toronto specialist becomes invaluable. There are several elections that can improve your residency status for a better tax result.

The § 6013(g) Election

This election is made by a U.S. citizen or resident alien married to a non-resident alien. Consequently, after the election, they are both treated as resident aliens for tax purposes.

• The Result: This makes it possible to file under the “married filing joint” status, accessing more deductions and credits.
• Constraint: This election can only be made once and remains in effect until revoked.

The § 6013(h) Election

This election is made by two married resident aliens where one or both are dual-status residents. This applies only to the year of the election and results in both spouses being taxed as full-year residents. Assuming both spouses continue to be U.S. residents, they can usually file a joint return going forward.

The § 7701(b)(4) Election

This is a first-year election made by a full-year non-resident who does not meet the substantial presence test. These are typically individuals who move to the U.S. after mid-year and do not hold a green card.

• The Result: After making this election, they become a dual-status resident—treated as a resident from the time they move into the U.S. to the end of the year, but as a non-resident before that point.

The § 7701(b)(4) & § 6013(h) Combination

It is also possible to combine elections. You can use § 7701(b)(4) to move from non-resident to dual-status, and then add the § 6013(h) election to be taxed as a U.S. resident for the whole year.

While this means you will be taxed on worldwide income, it grants access to significant U.S. tax benefits. This often makes sense for those moving from Canada, as Canadian tax rates are generally higher. You may be able to satisfy U.S. obligations using foreign tax credits and the foreign earned income exclusion.
