GBLT payment reference

The tax assessment number is your payment reference. You can find this number on your tax assessment notice.

GBLT’s Creditor identifier (CID)

The creditor identifier is a unique code assigned to an organization. This code allows the bank to identify which organization is initiating a direct debit. This makes it clear which company is debiting funds from your account. 
If you set up your direct debit in MijnGBLT, this number is already filled in. If you set up your direct debit in your own online banking portal, you’ll need GBLT’s CID.
 

GBLT’s CID is NL07ZZZ082053570000.
