Ah sorry! I read too fast.
I will be transferring the money to my wife's overseas account. It's relocating money for us as we are moving abroad.
Will that then just be the normal charges or is there something I should know?
You need to do it through your bank.
You need a tax clearance cert to show you don't owe any taxes.
You then need to sign an intent to emigrate. This allows you the max allowance in cash. It was R1 million per adult when I left in 2008.
In the week before you leave, you get a fat cheque which you take with you. Usually in the currency of country you are going to.
You then "hand" your account over to a bank official. This means that once you leave, you can only process transactions on your account through that official if there are remaining funds. They cut of your direct access.
After a time period you can then request that any balance be transferred into your account in the country you have moved to and the account closed completely. I can't recall what that time period was. It wasn't weeks though. Longer. Maybe a year.
Well that's how we did it. If it has changed then its probably less buearocratic than this.
Check with your bank.
Remember that you probably need to declare large amounts of cash when enter the other country. Don't try and be a smart ass and smuggle stuff in.
