First of all I am from Pittsburgh,Pa, USA,  retired & need some info on Spanish banking laws.

I have children who live in Madrid and are official residents NOT Spanish nationals, and they have local bank accounts.

I would like to send via my bank money transfers to their accounts I have been told that I need a SWIFT ID and the number of each bank account.  That is OK and I have all that info.

My question is, ” How much can I send before it is reported to Hacienda as additional income. “

Thanks in advance for all responses.

I think you need to speak to an accountant. Can’t really recommend one sadly. I’m sure you will find one on google though.
