Companies House is to contact Rangers' subsidiary Sevco Scotland Ltd after it filed an incomplete annual return.
The document submitted on 12 September contained no details of shareholding during the return period from the company's date of incorporation.
Annual returns usually provide details of the identities of shareholders.
Sevco Scotland Ltd was the company that acquired the assets of The Rangers Football Club PLC last summer after it formally entered liquidation.
Sevco Scotland Ltd changed its name to The Rangers Football Club Limited in July 2012 and is now wholly owned by The Rangers International Football Club PLC.
Companies House told BBC Scotland that it would raise the issue with Sevco Scotland Ltd and confirm if a second annual return was to be filed by the company.
