bank wants to know what the purpose of the business account is what must I enter

Account purpose is part of customer due diligence, not a separate control

The bank asks about the purpose of the account because it is a mandatory part of customer due diligence under the Anti-Money Laundering and Counter-Terrorist Financing Act (Wwft). This investigation is not a one-time exercise: the bank must keep its view of a customer current, and a question about the account's purpose therefore recurs when opening an account, when articles of association are amended, when a name changes, or simply periodically without a direct trigger. It is the same exercise as the question about the source of the company's assets—: the bank builds a risk profile, and the account's purpose is one of the standard fields within it.

What you enter is the actual function of the account in business operations: for example, daily payment transactions with suppliers and customers, salary payments, a savings account for reserves, or an account specifically for a participation or project. Align that description with what is listed in the Trade Register about the enterprise's activities (SBI code and business description, recorded under the Trade Register Act 2007), because a bank that sees a mismatch between stated purpose and registered activity often asks a follow-up question. If you do not have a ready-made formulation, use the business description from the Trade Register as a basis — that is verifiable and consistent with what has been stated elsewhere, for example when the banks where the company maintains accounts.

Basis: Wwft customer due diligence, not CSRD or Trade Register Act itself

The obligation to conduct customer due diligence — including determining the purpose and intended nature of the business relationship — derives from the Wwft. The Trade Register Act 2007 only requires registration of the core activity of the enterprise; these two sources must align with each other, but the bank's questioning obligation itself is rooted in the Wwft. The CSRD (Directive 2022/2464) plays no role here: it is a reporting obligation concerning sustainability, not client acceptance.
