Requesting an extension for filing a BOI report is possible under certain circumstances. To request an extension, submit a formal request to FinCEN before the original deadline. This request should detail the reasons for the delay and provide an estimated date for when the report will be filed. FinCEN will review the request and may grant an extension based on the provided justification. It's important to ensure that the extension request is made in a timely manner to avoid penalties for late filing.
