U.S. INDIVIDUAL FEDERAL TAX: Dual Residency in U.S. Tax

India to USA: A Practical Dual-Status Tax Case Study

PART 3 OF 3  —  PRACTICAL CASE STUDY

In Part 1, we understood the difference between a dual-status taxpayer and a dual-resident taxpayer.

In Part 2, we examined the important elections, IRS forms and filing formalities.

Now let’s put those rules into practice.

The following case study illustrates how a tax professional should approach an individual moving from India to the United States during the year.

Meet Arjun Mehta

THE TAXPAYER Arjun Mehta, an Indian citizen, works in India until June 30, 2026. On July 1, 2026, he moves to the United States to join a U.S. employer. Under the applicable U.S. residency rules, Arjun becomes a U.S. tax resident from July 1, 2026 and remains a resident through December 31.

The figures below are illustrative and are intended to demonstrate the analysis rather than calculate Arjun’s final tax liability.

Figure 1 — Arjun’s dual-status tax year at a glance

2026 Income Overview

Income	Amount	Period
Indian salary	₹18,00,000	Before July 1
U.S. salary	$80,000	After July 1
Indian bank interest	₹1,20,000	After July 1
Indian rental income	₹3,00,000	After July 1
U.S. bank interest	$2,000	After July 1
Capital gain	$5,000	After July 1
Indian income tax paid	₹4,50,000	During the year

STEP 1 Determine Arjun’s U.S. Status

Arjun is:

Period	Status
January 1 – June 30	Nonresident alien
July 1 – December 31	Resident alien

Therefore: Arjun has a dual-status tax year.

IRS GUIDANCE The IRS confirms that a dual-status year occurs when an individual is a resident for part of the year and a nonresident for the other part.

STEP 2 Divide the Tax Year

This is the first practical step in preparing the return.

IRS GUIDANCE A dual-status taxpayer is generally taxed on income from all sources during the resident period, and generally on U.S.-source income during the nonresident period.

STEP 3 Analyze the Income

Figure 2 — How Arjun’s 2026 income splits across the two residency periods

Indian Salary — ₹18,00,000

Arjun earned this salary before becoming a U.S. resident. Therefore, it belongs to his nonresident period.

Foreign-source income received during the nonresident period is generally not taxable in the United States merely because the taxpayer later becomes a resident. The precise source and tax treatment should nevertheless be confirmed under the applicable rules.

U.S. Salary — $80,000

This income arises during Arjun’s resident period. Therefore, it is generally taxable in the United States.

Indian Bank Interest — ₹1,20,000

This interest is received after Arjun becomes a U.S. resident. Therefore, it generally enters the U.S. worldwide-income analysis.

The fact that the bank account is located in India does not by itself remove the income from U.S. taxation during the resident period.

Indian Rental Income — ₹3,00,000

The rental property is in India, but Arjun is a U.S. resident when the income is received. Therefore, the rental income generally needs to be considered in his U.S. worldwide-income computation, subject to the applicable U.S. rules.

U.S. Bank Interest — $2,000

This is U.S.-source income and is generally taxable. Because it is also received during the resident period, it falls within the resident-period analysis.

Capital Gain — $5,000

This item requires additional analysis. We need to know:

●  What asset was sold?

●  Where was the asset located?

●  When was it acquired?

●  When was it sold?

●  Was Arjun a resident when the gain arose?

●  What sourcing rules apply?

●  Does a treaty provision affect the result?

KEY TAKEAWAY A professional tax preparer should not automatically classify every capital gain simply by looking at the taxpayer’s country of residence.

STEP 4 Determine the Correct Return

Question	Answer
Arjun is a U.S. resident on:	December 31, 2026
Therefore, he generally files:	Form 1040
…and writes across the top:	DUAL-STATUS RETURN
He attaches:	Form 1040-NR (as the dual-status statement)

The statement shows the income attributable to the period during which Arjun was a nonresident.

IRS GUIDANCE The IRS specifically provides this filing structure for a taxpayer who is a resident at the end of the year.

STEP 5 What About the Standard Deduction?

Arjun cannot simply claim the standard deduction because he became a U.S. resident. The IRS specifically states:

IMPORTANT A dual-status taxpayer cannot claim the standard deduction, even for the resident portion of the year.

Applicable itemized deductions must instead be considered under the relevant rules.

STEP 6 What About the Indian Tax Paid?

Arjun paid: ₹4,50,000 in Indian income tax.

Now we have reached another important international-tax concept: the Foreign Tax Credit.

If qualifying foreign income is also subject to U.S. tax, Arjun may potentially be eligible for a foreign tax credit, subject to the applicable requirements and limitations.

IRS GUIDANCE The foreign tax credit is intended to reduce double taxation when qualifying foreign-source income is taxed by both the United States and a foreign country.

IMPORTANT Foreign tax paid does not automatically mean an equal U.S. tax credit. The foreign tax must satisfy the applicable qualification tests, and the credit is subject to limitations.

STEP 7 What if India Also Treats Arjun as a Resident?

Suppose Indian domestic law also treats Arjun as a resident for the relevant year. Now we have:

●  U.S. domestic law → Resident

●  Indian domestic law → Resident

Arjun may therefore be a Dual-Resident Taxpayer.

The next step is to examine the applicable India–U.S. tax treaty.

IRS GUIDANCE If the treaty’s residence provisions resolve the conflicting claims in favor of India, the taxpayer may be able to claim treaty-based treatment as a nonresident of the United States for purposes of computing U.S. income tax, subject to the applicable requirements. The IRS generally requires Form 1040-NR and Form 8833 for such a treaty-based position.

KEY TAKEAWAY Dual-status and dual-resident are two separate analytical questions.

STEP 8 Arjun’s Professional Tax Analysis

The complete reasoning can now be summarized:

1. Determine residency	→ Resident from July 1
2. Divide the year	→ Nonresident period + Resident period
3. Classify income	→ U.S.-source / foreign-source / ECI
4. Apply the correct tax scope	→ Nonresident rules / worldwide-income rules
5. Determine the return	→ Form 1040 + Form 1040-NR statement
6. Check deductions	→ Standard deduction generally unavailable
7. Examine foreign taxes	→ Potential foreign tax credit
8. Check foreign residency	→ Possible dual-resident situation
9. Examine treaty	→ Tie-breaker and treaty-based position, where applicable

The Golden Framework

For any international taxpayer moving to or from the United States, remember:

Figure 3 — The seven-step Golden Framework

Status — Resident or nonresident?

Date — When did residency begin or end?

Source — Where did the income arise?

Income — What is taxable during each period?

Return — Form 1040 or 1040-NR?

Credit — Is foreign tax credit available?

Treaty — Does a tax treaty change the result?

Final Takeaway

Arjun’s case demonstrates that international taxation is not simply a matter of:

‘I moved to America, so all my income is taxable in America.’

Nor is it:

‘My income came from India, so America cannot tax it.’

The correct approach is more disciplined:

First determine residency. Then determine the residency period. Then classify the income. Then apply the appropriate U.S. tax rules. Finally, examine foreign-tax relief and treaty provisions.

That is the essence of dual-status taxation.
