@ncumimi , what is your US immigration status? If you are a US person ( citizen/GreenCard/ Resident for tax purposes ) and have income in South Africa ( where your bank is :(
(a) if you tax home is in South Africa,. then you should be able to use that account to transfer taxes due using that bank account. When I was a tax resident of Germany I used my local bank account . However, it is best to use a US bank or a local branch of US bank.
(b) Your refunds from the IRS can be a check ( if you choose that ) and cleared by your local bank ( they will use corresponding banks to do the needful for a price ).
(c) Generally IRS deals only with US banks and in US $.
Having said all of the above, I still wonder what you are trying to achieve? Why do you have to file a US return. If you want a little privacy you can always PM me ( just no PII -- Personally Identifiable Information, please ).
I look forward to hearing from you.
