In France,
The bank wrote to me saying: that in accordance with article 120 3 of the Code of Civil Procedure, this distribution constitutes income declared in the IFOP which is subject to social security contributions and obligatory as a deposit by immediate debit from your cash account.
Once said, once done, it's up to me to sort it out.
If the form bothers me, I think they are right in substance (distribution of dividends in the form of shares).
