Yes. Tier Points earned from your direct client's eligible deposits and qualifying trading activities before they become a Sub-IB will remain in your Tier Points balance, subject to the standard 12-month validity period.
However, once the client becomes a Sub-IB, their subsequent deposits and trading activities will no longer contribute to your Tier Points, as Sub-IB activities are excluded from ClubÉlite Tier Points calculations.
You can check whether a client is classified as a direct retail client or a Sub-IB by logging in to the IB Portal and navigating to the IB Report section.
