U.S. vs. India: A Tale of Two Tax Residency Systems

Determining an individual’s tax residency is a cornerstone of any country’s tax system, as it dictates how that person’s worldwide and domestic income is taxed. While both the United States and India use physical presence, the number of days spent in the country as a primary benchmark, their approaches diverge significantly in methodology, complexity, and classification.

Here’s a comparative look at the U.S. Substantial Presence Test and India’s multi-layered tax residency laws.

A Quick Recap: The U.S. Substantial Presence Test (SPT)

The U.S. system is relatively binary: for tax purposes, you are either a “Resident Alien” or a “Nonresident Alien.” The SPT is a purely mathematical formula to determine this status for a calendar year (Jan 1 – Dec 31).

To be a tax resident, you must meet both of these conditions:

1. 31-Day Test: Be physically present in the U.S. for at least 31 days in the current year.
2. 183-Day Weighted Test: The sum of the following must be 183 days or more:
   • All days in the current year.
   • 1/3 of the days in the first preceding year.
   • 1/6 of the days in the second preceding year.

This weighted formula is unique and requires careful calculation. If you meet both tests, you are a U.S. tax resident.

India’s Approach: A Multi-Tiered System

India’s tax residency rules, which apply to a financial year (April 1 – March 31), are more nuanced. An individual is not just a “resident” or “non-resident”; a resident is further classified, which has a significant impact on their tax liability.

The categories are:

1. Resident and Ordinarily Resident (ROR)
2. Resident but Not Ordinarily Resident (RNOR)
3. Non-Resident (NR)

Step 1: Determining “Resident” Status

An individual is considered a Resident in India if they satisfy any one of the following basic conditions:

1. Stay in India for 182 days or more in the financial year. OR
2. Stay in India for 60 days or more in the financial year AND 365 days or more in the 4 preceding financial years.

Special Condition: For Indian citizens or Persons of Indian Origin (PIO) visiting India, or for Indian citizens leaving for employment, the “60 days” in the second condition is extended to 182 days (or 120 days if their India-sourced income exceeds ₹15 lakh).

Step 2: Classifying a Resident as ROR or RNOR

Once a person is determined to be a “Resident,” a second set of “additional conditions” is applied to see if they are “Ordinarily Resident.” An individual becomes a Resident and Ordinarily Resident (ROR) only if they meet both of the following:

1. Have been a Resident in India in at least 2 out of the 10 preceding financial years and
2. Have stayed in India for a total of 730 days or more in the 7 preceding financial years.

If a Resident fails to meet even one of these two additional conditions, they are classified as Resident but Not Ordinarily Resident (RNOR).

Introducing a New Category: The “Deemed Resident”

India has also introduced a “deemed residency” rule. An Indian citizen with a total income (other than from foreign sources) exceeding Rs 15 lakh will be deemed to be a resident (specifically, an RNOR) if they are not liable to pay tax in any other country. This rule targets stateless individuals who may not trigger residency in any jurisdiction.
