Regulatory Compliance & Advisory

Federal & State Amended Tax Returns (Form 1040-X)

If you discovered overlooked deductions, received corrected tax forms (W-2c, revised 1099-B), need to change your filing status, or mistakenly filed the wrong return type (such as filing Form 1040 instead of Form 1040-NR while on an F-1 student visa), you must file Form 1040-X to amend your prior federal return.

Under Internal Revenue Code § 6511, taxpayers generally have 3 years from the date the original return was filed or 2 years from the date the tax was paid, whichever is later, to claim an additional refund. Our CPAs prepare comprehensive 3-column comparative amendment schedules and technical explanation statements that satisfy IRS audit criteria.

Can Form 1040-X be filed electronically?

Yes! The IRS accepts electronic filing for current and up to two prior tax years for Form 1040 and 1040-NR amendments.

How long does it take the IRS to process an amended return?

IRS processing typically takes 16 to 20 weeks. You can track status using the official IRS "Where's My Amended Return?" portal.

How do I know if I need to file Form 1040 or Form 1040-NR?

Your US tax residency status is determined by the IRS Substantial Presence Test (SPT) under IRC § 7701(b). You are classified as a Resident Alien (filing Form 1040) if you were physically present in the US for at least 31 days in 2026 AND 183 weighted days over a 3-year period (all current year days + 1/3 prior year days + 1/6 second prior year days). If you do not meet this threshold, you file Form 1040-NR as a Nonresident Alien. Students on F-1 visas are exempt individuals for their first 5 calendar years and generally file Form 1040-NR regardless of physical presence.

Who is legally required to file FinCEN Form 114 (FBAR)?

Under 31 U.S.C. § 5314, every US person (including US citizens, Green Card holders, and resident aliens on H-1B/L-1 visas meeting the SPT) who has a financial interest in or signature authority over foreign financial accounts must file an FBAR if the aggregate peak balance of all accounts exceeded $10,000 USD at any point during the calendar year. This includes Indian NRE, NRO, FCNR, Demat, mutual funds, EPF, and PPF balances. Nonresident aliens (Form 1040-NR filers) are exempt from FBAR filing.
