Yes, you can also add your VAT ID to your account at a later date.
However, please note the following:
If you have a balance of more than €10 in your account on the last day of the month, a credit note will automatically be created for you.
This credit note (in the form of a PDF) lists all your earnings for the month in question and is created based on your details. This means it is very straightforward for you and you do not have to send an invoice to SongPush.
If a sales tax ID (VAT ID) is stored in the account at the time the credit note is created (on the last day of the month), the credit note will be issued showing the sales tax and the amount will be paid out to you including sales tax.
Important:
If no sales tax ID (VAT ID) is stored in the account at the time the credit note is created, the credit note will be issued without showing the sales tax and the only the net amount will be paid out to you.
