Well, Simon, I stand corrected! There IS a 'carga inactiva' - it apparently was introduced in 2003 (blame Hippo!) i.e. before you got here. The rest of us should have known about it & obviously didn't.
The info I was given is a bit different to yours, so I'll post it for what it is worth. The 'carga inactiva' applies to savings accounts, both dollar & peso, I was told, but not checking or any other type of account. It applies after 3 months of inactivity (as opposed to the 6 you were told, I believe). The charge was 42.50 pesos per month until April of 2004 when it became 50 pesos (or dollar equivalent). I didn't enquire as to whether the money went to Banco Central as I was more interested in learning about 'circumventing strategies'.
It would appear 'inactive' means no personal appearance to engender a 'book' entry. It doesn't have to be your personal appearance, as long as its a 'body' that is ok. 'Activity' is classed as a withdrawal, a deposit or (get this!) the appearance of the 'body' with your book to get the entries of interest etc. updated.
I gave them my 'indisputable logic' as per earlier post. No that is a 'bank' transaction not a 'body' transaction, I was told. So........those are the facts(!). The application of the 'facts' seems less than consistent. As you know from the dates I posted yesterday, both of my accounts were well out of time for a 6 month 'carga inactiva' let alone a 3 month one. I promise you, Simon, I walked out of that bank with the carga inactiva applied to one account & NOT to the other! (You have my permission to check my books to verify).
So perhaps my earlier invitation to either fall about laughing or applaud should be changed to one to join me in scratching my head.................
BTW there do appear to be circumventional strategies, I obviously found one for one of my accounts, but I don't actually know WHAT it is! I gather shutting down the account & reopening it is a possible, but I didn't have the time (not after all of the above!) but if you try this one, Simon, let us know how you get on.
A bemused Lambada, still pondering the mysteries of life & Dominican banking!
