No, you cannot use the Streamlined Filing Compliance Procedures if you willfully failed to report foreign financial assets. The Streamlined Procedures are specifically designed for taxpayers who can certify that their failure to report foreign financial assets and pay all tax due in respect of those assets was not due to willful conduct on their part. Willful conduct implies intentional or voluntary disregard of the legal duty to report foreign financial assets and income.
If the IRS determines that a taxpayer's actions were willful, the taxpayer would not be eligible for the Streamlined Procedures and could be subject to higher penalties and even criminal prosecution.
