Setting up payment allocation for G account and BASt

Continia Banking includes several predefined payment allocation types that cover common allocation scenarios. These include types for partial payments, G account allocations, and VAT allocations, allowing you to configure payment allocation behavior without creating custom allocation types.

A G account is a specialized bank account used in the Netherlands to hold funds for tax and social security payments, keeping them separate from general vendor transactions. Setting up a G account allocation in Continia Banking ensures that a fixed percentage of each vendor payment is transferred to the designated G account.

German regulations require the handling of construction withholding tax (Bauabzugsteuer, or BASt) at a fixed rate of 15 percent. Continia Banking provides a predefined BASt payment allocation type with a fixed percentage of 15 percent.

The predefined G account and BASt types are imported from the Setup Server and you can find them on the Payment Allocation Types page.
