U.S. State Income Tax for NRIs: Residency and Filing Rules

Moving from the United States to India does not automatically end your U.S. state income-tax obligations. You may still have to file a state return if you remain a resident under that state’s rules or continue receiving income sourced to that state.

This is separate from your federal tax position. An Indian citizen may qualify as a nonresident alien for federal tax purposes but still be treated as a resident or part-year resident by a particular state.

The rules are especially important for NRIs who previously lived in California, New York or New Jersey, work remotely from India, own U.S. property or receive income from a U.S. business.

When Does an NRI Have to Pay U.S. State Income Tax?

An NRI may have a state income-tax obligation if any of the following applies:

• The NRI remains domiciled in the state.
• The NRI satisfies the state’s statutory-residency test.
• Employment services were performed in the state.
• The NRI owns rental property in the state.
• The NRI sold real estate located in the state.
• Business or partnership income is allocated to the state.
• State income tax was withheld and a return is required to claim a refund.

“NRI” is an Indian tax and FEMA classification. U.S. federal law generally uses the terms resident alien and nonresident alien. A person who is a federal nonresident alien may still have a state filing obligation because states apply their own residency and income-sourcing rules.

How Is State Tax Residency Determined?

State residency commonly depends on domicile and physical presence.

Domicile

Domicile is the place you consider your permanent home and intend to return to. A state may examine:

• Where your spouse and children live
• Whether you maintain a home in the state
• Driver’s licence and vehicle registration
• Voter registration
• Mailing and financial addresses
• Business and professional connections
• Location of valuable personal belongings
• Statements made in legal and tax documents

Moving to India while retaining a home, driver’s licence and substantial personal connections in the former state may make it difficult to prove that state domicile ended.

Statutory residency

Some states can treat you as a resident based on the number of days you spend there and whether you maintain a permanent place of abode.

For example, New York may treat a person as a resident if they maintain a permanent place of abode and spend 184 days or more in New York during the year. Domicile is a separate test, so failing the day-count test does not necessarily end residency if New York remains the person’s permanent home.

NRIs who travel frequently between India and the United States should maintain accurate travel and accommodation records.

What Income Can a State Tax?

A state resident may generally be taxed on income from all sources, subject to that state’s rules. A nonresident is generally taxed only on income sourced to the state.

A nonresident state return may therefore be required even when the NRI lives permanently in India.

For example, an NRI living in Mumbai who owns an apartment in New Jersey may have to report the property’s rental income on a New Jersey nonresident return.

California, New York and New Jersey Rules for NRIs

California

California treats an individual as a resident when either:

• the individual is present in California for something other than a temporary or transitory purpose; or
• the individual is domiciled in California but remains outside the state for a temporary or transitory purpose.

Therefore, an NRI who accepts a short overseas assignment in India but intends to return to California may continue to be treated as a California resident.

A genuine permanent move requires more than physical departure. The taxpayer should establish stronger connections with India and reduce California ties.

After California residency ends, California-source income can remain taxable. Examples include:

• Rent from California property
• Gain from California real estate
• Salary for services performed in California
• Income from a California business

California also uses total income when calculating the effective rate applicable to California taxable income for certain nonresidents and part-year residents. This does not mean all worldwide income is taxed as California-source income, but the other income can affect the applicable rate.

New York

New York examines both domicile and statutory residency.

An individual can continue to be domiciled in New York until they clearly abandon New York as their permanent home and establish a new permanent home elsewhere.

New York may also treat someone as a statutory resident when the person maintains a permanent place of abode and spends 184 days or more in the state.

Remote workers must consider New York’s convenience-of-the-employer sourcing rule. Under this rule, certain days worked outside New York for personal convenience may remain New York workdays when the employee’s assigned or primary office is in New York.

However, this rule should not be applied automatically to every NRI working from India. The employer’s location, assigned office, reason for remote work and employment arrangements must be examined.

New Jersey

New Jersey residents generally report taxable income received from all sources. A nonresident may need to file when their income for the entire year exceeds the applicable filing threshold and they received New Jersey-source income.

If an NRI lived in New Jersey for part of the year and continued receiving New Jersey-source income after moving to India, both part-year resident and part-year nonresident reporting may be required.

New Jersey confirms that part-year residents report income earned or received while resident, while nonresidents remain taxable on qualifying New Jersey-source income.

What Happens When an NRI Moves to India Mid-Year?

An NRI who permanently moves to India during the calendar year may need to file a part-year resident return.

The return generally separates:

1. Income taxable while the person was a state resident; and
2. State-source income taxable after the person became a nonresident.

Suppose Priya lived and worked in California until 30 June and then permanently relocated to India. She continued renting out her California property.

Priya may need to:

• Report income received during her California-resident period.
• Allocate salary according to where the services were performed.
• Continue reporting California rental income after moving.
• Establish that her post-move Indian salary is not California-source income.
• File the applicable part-year or nonresident California return.

She should retain flight records, Indian employment documents, housing records and evidence showing that California connections were reduced.

Does the India–U.S. Tax Treaty Apply to State Tax?

Not necessarily.

The India–U.S. tax treaty may provide federal tax relief on qualifying income. However, individual states are not automatically required to follow federal treaty treatment.

The IRS specifically states that some states honour U.S. tax treaties while others do not. The taxpayer must check the law of the state in which they live or from which the income arises.

Therefore, income exempt from federal tax under a treaty may remain taxable on the state return.

Foreign tax credits also vary. An NRI should not assume that Indian income tax claimed as a federal foreign tax credit will automatically produce an equivalent state credit.

Which State Return May an NRI Need?

Depending on the circumstances, an NRI may file:

• Resident return: Generally used when the person remains a full-year state resident.
• Part-year resident return: Used when state residency begins or ends during the year.
• Nonresident return: Used to report income sourced to the state while living elsewhere.
• Multiple state returns: Required when income arises from more than one state.

A federal filing extension does not necessarily satisfy state-extension requirements. The NRI should confirm the form, deadline and payment rules directly with each relevant state.

Documents NRIs Should Maintain

Keep the following records:

• Passport and U.S. immigration documents
• Federal and state tax returns
• Form W-2, Form 1099 and Schedule K-1
• Travel calendar and flight records
• Indian employment agreement
• Indian and U.S. housing documents
• Property rental and sale records
• Evidence of state domicile changes
• State tax withholding statements
• Remote-work agreement
• State tax notices and payment records

These documents help establish the date residency ended and support income allocation between jurisdictions.

Conclusion

U.S. state income tax for NRIs depends on residency and income source—not simply where the individual currently lives.

An NRI may remain a state resident after moving to India if domicile was not properly changed. Even after residency ends, rental income, property gains, business income and salary connected with the former state may remain taxable.

California, New York and New Jersey apply different tests, so each state must be evaluated separately. NRIs should document their move carefully and review state obligations independently from their federal tax return.
