Correct me if I'm wrong, but if you do not financially emigrate you're still a taxable citizen of the country? So that will require you file a tax return etc every year?
No.
ZA tax laws - while convoluted (some of the rules have back-dating type effects) - are quite clear on who gets taxed.
This "official emigration" stuff discussed here features only tangentially there. It's one of triggers that can break your tax residency but only
one of many. And those others get triggered by simply leaving. Like 1 of the 50 people I know that left actually did that.
That's why I'm saying you only really need it if you need to crack open an RA or go above the fx exchange limit of 10/11m.
Basically if you do a "proper" emigration with the whole kiss grandma goodbye I'm going to Perth then you're home free in terms of taxation. If you're working on an oil rig for a couple months...that's where it gets tricky.
The grandma scenario has a bit of a twilight effect going though where you end up in scenarios where technically you need to declare cash, pay tax and then get it back. See backdating above. A lot of people just say fk it...don't declare in those scenarios. It's a bit shady in that's it's breaking the law, but amounts to giving SARS R100 and then 3 months later asking SARS for a R100 refund...so to each their own. See vamp's post
Also...no idea wtf people are on about with "financial emigration" in this thread. There is no such thing. There is the whole blocked account thing - which goes hand in hand with an impending actual physical emigration and then there is moving assets offshore. That's it.
Just as an aside to this, I would imagine in the future years the ANC will get desperate and change the laws to state your overseas income is also taxable in SA or some other type of nonsense.
Not happening. Firstly zero chance of enforcement so it's futile, second bad PR, third the crowd they'd p.iss of is connected. Remember all those FDI inflows that literally keep the SA finances alive...that foreign money comes with an implicit understanding that senior staff is globally mobile. You tell those guys they'll be personally taxed suddenly & unexpectedly and there will be a riot. (Source - been there done that).
