How long does a refund take?

On Thursday last week I got a letter of completion from SARS, on Friday Morning my Statement of account saying i'm due a refund and I check i'm not selected for audit or verification. When can I expect the refund in my account?

It should take a few days, provided you don't have prior year returns outstanding and SARS does not need to verify your bank details (but you should have received a letter if the latter was the case).

You could call the Helpdesk on 0800 007 277 to follow up if there is anything outstanding.

Why haven't I received my tax refund yet?
