First-Year Dual Status

In the year you move to the US and become a tax resident, you typically have a dual-status tax year. You are a nonresident for part of the year and a resident for the remainder. This split affects which income is taxable, which deductions are available, and which forms you file.

Key Points

  • Dual-status means you were both a nonresident and resident alien in the same tax year.
  • As a nonresident, only US-source income is taxable; as a resident, worldwide income is taxable.
  • You cannot use the standard deduction in a dual-status year.
  • The first-year choice election under IRC 7701(b) can simplify filing by treating you as a full-year resident.
  • Joint returns are generally not available in dual-status years unless you make a special election.

Action Items

  1. 1.Determine your residency start date based on the SPT or green card test.
  2. 2.Split your income into nonresident and resident portions for the dual-status return.
  3. 3.Evaluate whether the first-year choice election produces a better tax result.
  4. 4.File Form 1040 for the resident portion with a Form 1040-NR statement attached for the nonresident portion.

Frequently Asked Questions

Can I file jointly with my spouse in a dual-status year?

Not by default. However, you can elect under IRC Section 6013(g) to treat the nonresident spouse as a resident, allowing a joint return. This means worldwide income is reported for both spouses.

What is the first-year choice election?

Under IRC 7701(b)(4), you can elect to be treated as a full-year resident if you meet the SPT in the following year and were present 31+ consecutive days in the arrival year.

TFSA US Tax Trap

The Tax-Free Savings Account is tax-exempt in Canada but receives no treaty protection in the US. The IRS classifies a TFSA as a foreign grantor trust, requiring Forms 3520 and 3520-A annually. Failure to file can result in penalties starting at $10,000 per form per year.

FBAR Filing Requirements

The Report of Foreign Bank and Financial Accounts (FBAR) must be filed by any US person with foreign financial accounts exceeding $10,000 in aggregate at any point during the year. The FBAR is filed electronically with FinCEN, not the IRS, and has its own deadline and penalty regime.

Core

Substantial Presence Test

The Substantial Presence Test (SPT) uses a weighted formula across three years to determine if a foreign national is a US tax resident. If you meet the test, you are taxed on worldwide income. Understanding the SPT is essential for snowbirds and anyone splitting time between Canada and the US.
