April 15, 2027 is the main U.S. federal filing deadline for many India-to-U.S. movers reporting both Indian and U.S. income for tax year 2026.

People who keep old statuses can be treated as full residents in two places at the same time, leading to dual taxation until they correct their records.

H-1B visa holders may be resident aliens, nonresident aliens, or dual-status filers based on their days of presence in the United States during 2025 and prior years, which impacts how they file taxes and what income is taxable.

U.S. tax residents with India activity like property or frequent cash movements may need to report these assets under IRS rules, including FBAR and Form 8938 filings.

NRIs must document their entry/exit dates to determine 182-day residency under Section 6 and report and pay tax on Indian-sourced income accordingly.
