How far back do I have to file if I missed U.S. tax returns for ten years?

Under the Streamlined Foreign Offshore Procedures, you file the 3 most recent tax years and 6 years of FBARs, regardless of how many more years you missed. The IRS generally does not require pre-Streamlined years to be filed, but you must certify non-willfulness and include all required information in the 3-year window.

Streamlined scope:

  • 3 tax returns: Three most recent years for which the due date has passed
  • 6 FBARs: Six most recent years (often differs from tax year count)
  • Current year: File normally by the current deadline
  • Earlier years: Not required unless IRS requests

When earlier years may matter:

  • Refund claims: Only the 3 prior years are eligible for a refund
  • Carry-forwards: NOL, capital loss, and FTC carryovers may require earlier years to be reconstructed
  • Dual-status or expatriation year: Earlier years may be requested by the IRS
  • IRS specifically requests: Respond to request; do not volunteer unless helpful

Practical approach for 10 missed years:

  • Gather records for all 10 to support the non-willfulness narrative
  • File 3 tax years + 6 FBARs per the Procedures
  • Write a strong certification showing a non-willful origin and discovery timeline
  • Keep records for all years in case of inquiry

Non-willfulness narrative:

  • Explain when and how you learned of the requirement
  • Explain why you did not file earlier (confusion, reliance on advice)
  • Show cooperation once aware
