Fixing past returns: Form 1040-X, missed FBAR and unreported Indian income

Many Indian-origin families find out years later that an Indian bank account never made it onto a return, or that an FBAR was never filed. This guide explains how to amend a US return with Form 1040-X, and which IRS route fits which situation. The answer depends on what was missed and, above all, on why.

Amending with Form 1040-X

Use Form 1040-X to change your filing status, income, deductions, credits, dependents or tax. You do not need to amend for a simple error the IRS has already corrected.

• Refund claims generally must be made within 3 years after you filed the original return, or 2 years after you paid the tax, whichever is later. Some situations, such as foreign tax credits, have longer windows.
• Extra tax: if the amendment shows more tax, pay it with interest as soon as you can. Waiting only adds interest.
• How: tax software can e-file Form 1040-X for recent years. Paper is required for tax year 2021 and earlier. You can track the status online with the IRS "Where's My Amended Return" tool.
• One year at a time: each tax year needs its own Form 1040-X.

A missed Indian bank interest or rental income, a missed foreign tax credit and a changed filing status are all normal reasons to amend. See the overview of Indian income on a US return.

Missed Form 8938 or FBAR

Form 8938 is attached to your annual return or to an amended return. It is not sent on its own. The IRS instructions explain that if it is not filed, the time the IRS has to assess tax on that return may stay open until 3 years after the form is filed. The base penalty for not filing is $10,000, with more if the IRS sends a notice and you still do not file (up to $50,000 in total). See FBAR and Form 8938.

The FBAR (FinCEN Form 114) is not filed with your tax return. It is filed online through FinCEN's BSA E-Filing system. The IRS says that if the IRS has not contacted you and you are not under civil or criminal investigation, you should file the late FBAR as soon as possible and explain the reason for the lateness. Civil penalties are adjusted each year: for penalties assessed on or after January 17, 2025 the non-willful figure is $16,536 and the willful figure starts at $165,353 (these may have been updated again since).

Which route fits which person

Delinquent information returns

For taxpayers who are not under examination and have not been contacted by the IRS, the delinquent international information return procedures say to file late Forms 3520 and 3520-A under the instructions for those forms. Other late information returns go in with an amended income tax return. You may attach a reasonable cause statement to each. Penalties can still be assessed. See Form 3520 in depth.

Streamlined procedures

Both streamlined procedures need you to certify that the failures were non-willful: negligence, inadvertence, mistake or a good-faith misunderstanding of the law. Neither is available if the IRS has started a civil examination of any of your returns, or if you are under criminal investigation.

Streamlined Foreign Offshore is for people living outside the US. A US citizen or green card holder must have had no US abode and been physically outside the US for at least 330 full days in at least one of the last three years. A non-citizen must have failed the substantial presence test in at least one of those years. You file 3 years of returns and 6 years of FBARs, with Form 14653, and the IRS says there are no penalties for failure to file, failure to pay, accuracy, information returns or FBAR for compliant filers. A person on an H-1B in the US will usually not qualify, because they meet the substantial presence test and have a US home. It can fit someone who moved back to India.

Streamlined Domestic Offshore is the route for most US residents. You file amended returns (Form 1040-X, not delinquent originals) for the last 3 years, so you must already have filed those returns. If you never filed original returns for those years, this route is not open to you: the IRS expects delinquent original returns instead, and a person who may have acted wilfully should speak to a US tax attorney before choosing any procedure. You file FBARs for 6 years, send Form 14654, and pay the tax and interest plus a one-time 5% miscalculated penalty on the highest aggregate year-end balance of the foreign assets in the covered period. Documents are mailed to the IRS in Austin, and not filed online.

If you earlier used a "quiet" correction, the IRS says you may still use streamlined, but penalties already assessed will not be reversed.

When willfulness is possible

Willful means a deliberate act to hide income or assets, or avoid filing or paying. It is not the same as a mistake. If you knew about the account and chose to say nothing, or a preparer asked and you said no, do not self-certify on Form 14653 or 14654. The IRS Criminal Investigation Voluntary Disclosure Practice exists for willful cases, with its own application (Form 14457). It must be made before the IRS starts an exam, and it does not guarantee immunity. Do not use it for honest errors.

When to bring in a US CPA

Involve a US CPA or tax attorney before submitting anything under a streamlined or voluntary disclosure procedure, when several years and large balances are involved, when an IRS letter has already arrived (see IRS letters), or if there is any doubt about willfulness.
