Hi Dexter,
|
|
|
|
Dear Dexter,
|
|
|
|
I hope this email finds you well. I am writing to inform you regarding your annual California Statement of Information (Form SI-550) submission requirement. Our records indicate that your report is now ready for filing with the California Secretary of State.
|
|
|
|
Please be advised that to avoid any late filing fees or penalties from the state of California, the submission deadline is November 31st. The current filing fee is $25, and late submissions may incur a $250 penalty. We strongly encourage you to complete this important California compliance requirement before the specified date.
|
|
|
|
Should you require any assistance with the filing process through the California Secretary of State's website or have any questions about California corporate filing requirements, please don't hesitate to reach out to our support team.
|
|
|
|
Best regards,
|
|
Compliance Team
