The penalty for the late filing of Form W-8EXP (Certificate of Foreign Government or Other Foreign Organization for United States Tax Withholding) depends on the specific circumstances and the discretion of the IRS. Generally, the penalty for failure to file correct information returns (such as Form W-8EXP) can range from $270 to $550 per form, with additional penalties if the failure is deemed intentional. However, if reasonable cause for the late filing can be demonstrated, the penalty may be waived or reduced. It is always best to consult with a tax professional or the IRS for specific guidance in individual cases.
