For the 2026 filing season, “Tax Day” returns to its traditional schedule. However, for Indian expats and immigrants, a single deadline is a myth. Depending on whether you are an H-1B professional in California, an F-1 student in New York, or an investor living back in India, your calendar looks very different.
Missing these dates doesn’t just result in interest for Indian nationals, it can trigger “non-willful” disclosure penalties that start at $12,500 per violation.
1. The Core Deadlines: April 15, 2026
This is the primary hurdle for most Indian taxpayers living in the U.S. (Resident Aliens).
- Income Tax Return (Form 1040): Deadline to file and pay any tax owed for the 2025 tax year.
- FBAR (FinCEN Form 114): The initial deadline to report your Indian bank accounts.
- 1st Quarter Estimated Tax: If you have significant 1099 income or Indian rental income, your first payment for the 2026 tax year is also due today.
2. The “Expat” Automatic Extension: June 15, 2026
If you are an Indian citizen who was physically living outside the U.S. or Puerto Rico on April 15, you receive an automatic two-month extension to file.
- The Catch: This is an extension to file, not to pay. If you owe the IRS money, interest begins accruing on April 15, even if you file in June.
3. The Fall Cleanup: October 15, 2026
If you filed Form 4868 by April 15, this is your final hard deadline.
- Extended Tax Return: Final day to submit your 2025 Form 1040 or 1040-NR.
- FBAR Final Deadline: FinCEN grants an automatic extension for the FBAR from April to October. No separate extension form is required for the FBAR; however, October 15 is the absolute final cutoff.

4. Quarterly Estimated Tax Payments (2026 Year)
If you are an Indian entrepreneur or a professional with high investment income in India (not subject to U.S. withholding), you must pay “as you go” to avoid underpayment penalties:
- Q1: April 15, 2026
- Q2: June 15, 2026
- Q3: September 15, 2026
- Q4: January 15, 2027
5. A Note on India’s Tax Year
Remember that India’s financial year runs from April 1 to March 31, while the U.S. uses the calendar year. When preparing your 2026 U.S. filing, you must mathematically split your Indian bank interest and TDS certificates to match the U.S. Jan-Dec 2025 window.
