Fully disclosed and Omnibus and OmniSub and their relationship with CRS

Today, I had a detailed discussion with Brother Wu @qinbafrank about the relationship between Fully disclosed, Omnibus, and OmniSub and CRS. Although it sounds complicated, it may actually have a significant impact on future tax information exchanges for everyone.

First, let’s talk about what Fully disclosed, Omnibus, and OmniSub are.

Fully disclosed, fully disclosed account model.

In this model, the information of the end user is disclosed to the underlying broker, and the underlying broker will establish independent accounts for each end user. For example, if a platform connects to Alpaca, under the Fully disclosed model, the information of each user will be submitted to Alpaca, and Alpaca will know who each user is and create independent securities accounts within the Alpaca system.

At this point, the platform acts more like a front-end entry point or introducing broker, responsible for introducing users to the underlying broker, managing user experience, order entry, and product display, while core broker functions such as underlying accounts, securities custody, trade confirmations, statements, tax documents, etc., are mostly handled by the underlying broker.

Thus, the key to Fully disclosed is whether the users are individually identified by the underlying broker and whether independent securities accounts are formed.

Omnibus, omnibus account model.

In this model, the underlying broker usually sees a main account at the partner or platform level, and the end users do not necessarily become independent account clients of the underlying broker one by one.

The platform has a comprehensive account at the underlying broker where all end users' assets, positions, and transactions may be summarized under this account, and then the platform itself maintains sub-accounts, ledgers, equity records, and KYC management for each user within its internal system.

Therefore, the key to Omnibus is that what the underlying broker mainly sees is the platform or partner, and the end users are more about being clients in the internal ledger of the platform.

OmniSub, sub-account model under the omnibus account.

OmniSub refers to the technique of accounting with Omnibus + sub-accounts. This means that the legal structure is still an omnibus account, held by a partner at Alpaca, but the Alpaca database provides a set of sub-account accounting systems that can track different end users' transactions, positions, cash, and company actions on a technical level.

Although OmniSub appears to have sub-accounts for each user, these sub-accounts are not fully disclosed broker accounts at the broker level. They are merely a technical accounting layer above the omnibus account. Whether end users become independent account clients of the underlying broker depends on the legal structure of the account.

Thus, the relationship between the three and CRS can be directly understood as:

Under Fully disclosed, end user accounts are opened one by one at the underlying broker. If the underlying broker is a U.S. broker, it mainly looks at the U.S. tax system, and if the underlying broker is in a CRS jurisdiction, then local CRS rules need to be considered.

In simple terms, it means that under the Fully disclosed model, if linked to a U.S. broker, then it has no relation to CRS.

Under Omnibus, the underlying broker sees the platform’s main account, and end user information is mainly maintained on the platform side. If the jurisdiction where the platform is located participates in CRS and the platform is a reporting financial institution, it may involve CRS.

Under OmniSub, although there is technical accounting for sub-accounts, the essence is still close to Omnibus. Therefore, the conclusion drawn is the same as for Omnibus.

In simple terms, it means that under the Omnibus or OmniSub model, regardless of whether it is linked to a U.S. broker, it may still involve CRS.

Fully disclosed, Omnibus, and OmniSub themselves do not directly determine whether CRS applies; what determines is where the end user information and account rights remain. CRS truly looks at the institution maintaining the financial account, the location of the account, the user's tax residency status, and whether it belongs to reportable financial accounts.
