CFIUS Case Management System 

Frequently Asked Questions 

Why is CFIUS implementing the Case Management System (CMS)? 

CFIUS implemented the CMS to allow parties to submit all transaction-related information 

through a single portal in a standard and secure manner. As of June 1, the CMS must be used to 

file any written notice or any declaration pursuant to 31 C.F.R. part 800 or 31 C.F.R. part 802. 

USING THE CMS 

How will I know that my submission of information to CFIUS through the CMS was 

successful? 

After submitting information through the CMS, you will receive a confirmation email. Active 

cases will also display on the dashboard module for easier management and additional 

submission confirmation. 

What should I do if I have a question regarding the CMS? 

Please first read the User Manual located here. If the User Manual does not address your issue, 

or if you are encountering technical issues, contact CFIUS.itsupport@treasury.gov. For 

technical issues related to ID.me, click here. For questions about the CFIUS process as it relates 

to the CMS or to provide feedback regarding the CMS, contact CFIUS.cms@treasury.gov. 

Do I submit responses to CFIUS information requests through the CMS? 

Parties will receive an information request from CFIUS via an email from Treasury staff, sent via 

the CMS. To make requested edits to a filing please return to the CMS portal and edit your 

submission there. To submit responses to other requests for information, simply reply to the 

email from the CMS. If you wish to reply confidentially, remove the individuals from the cc line 

that you do not wish to share your response with. 

Do I need to submit draft notices through the CMS? 

Yes. Parties should submit draft notices through the CMS portal. Submission of a draft notice aids 

the Committee’s understanding of the transaction and provide an opportunity for the Committee to 

request additional information to be included in the notice, if necessary. 

How is a filing fee submitted with a notice through the CMS? 

Beginning on August 9, 2020, filing fees must be submitted through Pay.gov via the CMS portal. 

The CFIUS Filing Fees page contains information on filing fees and submission instructions. In 

addition, the CMS User Guide on the CMS page and the Payment Instructions document contain 

detailed information on how to submit a filing fee through the CMS portal. Because filing fees 

are submitted directly through the CMS portal, users do not need to include a receipt with their 

formal filing; however, CFIUS recommends that users retain a copy of the receipt for 

recordkeeping purposes. CFIUS cannot deem a formal filing complete until it has received the 

filing fee payment. 

Is an ID.me account needed to submit a filing fee? 

Yes. An ID.me account is necessary to access the CMS portal and pay the filing fee. Instructions 

to create an ID.me account are found on the CMS page on the CFIUS website.

How will I know if my submission of a filing fee is successful? 

Once a user submits a filing fee through the CMS portal, they will be taken to a “CFIUS – 

Payment Success” page. If a payment is successfully submitted to Pay.gov, the payment status 

will say “Payment Submitted – Pending Receipt.” Once the payment has cleared, the payment 

status will say “Payment Received,” indicating that the Pay.gov system has received the filing fee 

payment. If a payment is not successful, the payment status will say “Payment Failed.” 

What should I do if the payment status says “Payment Failed”? 

Users should contact Pay.gov at https://www.pay.gov/public/home/contact. 

UPLOADING INFORMATION THROUGH THE CMS

How do restricted uploads work? 

Documents, such as personal identifier information, that are not to be accessed by other 

individuals on a filing must be uploaded as a “Restricted Document.” If you upload a 

Restricted Document, then the uploader and CFIUS will be the only ones with access to the 

Restricted Document; no other individuals will be able to see the title of the Restricted 

Document. 

Are there limits on file sizes? 

Yes. The CMS accepts individual files up to 20 megabytes in size. 

Can I upload a document instead of filling out a portion of the web form? 

While certain fields of the web form require data for saving, processing, and submission, in order 

to streamline the efficiency of the CMS, parties are encouraged to upload Excel files for large 

spreadsheets. In addition, parties may upload confidential responses as a separate document and 

enter “see Exhibit #” in the web form. However, parties may not simply defer all responses to 

attachments when submitting a declaration or filing a notice. Treasury may reject declarations 

and request the refiling of notices that only reference attachments. 

What file formats can the CMS accept? 

The CMS accepts Excel, Word, and PDF files. 

Will CFIUS begin to review the information saved in the form before it is submitted? 

Information saved prior to submission is stored in the CMS web platform hosted by the 

Department of the Treasury. However, a CFIUS case officer will not begin review of the 

information until the draft or formal written notice has been submitted through the CMS. 

PARTY ADMINISTRATION

What is a Filing Admin? 

A filing admin is a user on a filing with permission to add or remove other users on the filing. A 

filing admin may add new users either as additional filing admins or as a non-admin user. Nonadmin users can view all non-restricted uploads and submit the filing but cannot add or remove 

other users. The initial creator of a submission will always be a filing admin.

What is a Payor? 

“Payor” is the designation given to a CMS user that only has permission to pay a filing fee. 

CMS users that are listed as contacts in a filing may designate a payor in instances when a 

person does not have a need to access the rest of the information contained in the CMS portal in 

connection with the filing of a notice. Contacts listed in a notice filing who are not designated 

as “Payors” may also submit the filing fee. 

How do I remove someone from a filing in the CMS? 

Individuals added to a filing through the CMS are given broad permissions, including the ability 

to view or edit most documents and submit the filing to CFIUS. If they are added as filing 

admins, they can also remove other users from a filing or add new users as filing admins. For 

this reason, please use discretion when determining which individuals to add and at what level of 

permission. You can remove yourself by going to the Participant Administration tab, finding 

your email address, clicking on the dropdown arrow, and selecting ‘Delete.’ A filing admin may 

also remove other users on the Participant Admin tab. If neither of these methods are available 

to you, email the designated case officer and CFIUS@treasury.gov to request assistance. 

PRE-FIRRMA TRANSACTIONS 

Certain aspects of my transaction occurred prior to February 13, 2020, according to the 

applicability rule at 31 C.F.R. § 800.104 or 31 C.F.R. § 802.104. Do I need to submit 

information to CFIUS through the CMS? 

Yes. Parties who believe their transaction should be submitted to CFIUS under the pre-FIRRMA 

regulations according to the applicability rule should still submit their transaction through the 

CMS. This includes transactions submitted under the critical technology pilot program 

regulations at 31 C.F.R. part 801. There is no need to fill out the fields in the Case Management 

System for pre-FIRRMA transactions. Instead, parties should upload the declaration or notice 

and any other files using the “Upload Documents” function in the Case Management System. To 

submit a draft filing, no further action is needed, simply click “Submit Draft.” To submit a 

formal filing under the pre-FIRRMA regulations, please ask your case officer to waive the 

system’s field validation for you. Once your case officer confirms this has been done you can 

click the “Submit Formal” button to submit your formal filing.
