A streamlined submission generally covers three years of federal income tax returns and six years of FBARs, but the exact years depend on the filing dates and whether a return was already filed. Counting backward from the current calendar year without checking due dates can produce the wrong package.
Unsure which years belong in the package?
Create a year-by-year filing history before amending or filing anything.
Request a compliance reviewThe three-year tax-return period
Use the most recent three tax years for which the U.S. tax-return due date, including a valid extension, has passed. Depending on timing, the newest calendar year may not yet belong in the submission. Each covered year should include the complete return and any required international information returns.
Domestic streamlined taxpayers generally submit amended returns for covered years that were filed incorrectly. Foreign streamlined taxpayers may submit delinquent or amended returns under the applicable instructions. The filing history must be reviewed before choosing the form and package format.
The six-year FBAR period
The FBAR portion generally covers the most recent six years for which the FBAR due date has passed. FBARs are filed electronically through FinCEN’s BSA E-Filing System, not attached to the income-tax returns. Each FBAR should report all required foreign financial accounts for that year, not only the accounts that produced income.
Example of the counting method
Assume a taxpayer prepares a submission after the 2025 income-tax and FBAR deadlines have passed. The covered tax-return years may be 2023 through 2025, while the FBAR period may be 2020 through 2025. If an extension changes whether a return’s due date has passed, the result can differ. Always apply the current IRS instructions to the actual submission date.
What if older years are also missing?
The streamlined lookback does not erase the need to understand older noncompliance. Older facts can affect eligibility, the non-willful narrative, account tracing, basis, carryovers, and later returns. The IRS may also request information outside the standard package in an examination. Do not destroy or ignore older records simply because they are outside the filing set.
Build a filing-history matrix
For every year, list whether the return was filed, the filing date, whether worldwide income was complete, which international forms were required, whether an FBAR was filed, the accounts involved, and any IRS contact. Add columns for amendments, tax, interest, and source documents. This single schedule often reveals gaps that a return-by-return review misses.
Common counting mistakes
- Using three FBAR years instead of six;
- Including a year whose due date has not passed;
- Leaving required Forms 8938, 3520, 5471, 8621, or 8858 out of a covered return;
- Filing FBARs with the IRS return instead of through FinCEN;
- Assuming an extension applies when none was valid;
- Failing to reconcile accounts that changed names or institutions; and
- Using the filing years before deciding whether streamlined is the correct option.
Map the years before preparing the forms
A filing-history review helps define the correct package and identify records still needed.
