As far as I understand, those who have purchased properties and signed the SPA before the implementation of the GST are still subjected to the 6% levy as developers have already begun to include a GST clause in their agreements in order to protect their margins. Means that you might end up paying additional charges anyway. Any GST incurred will be passed on to purchasers of commercial properties and even if you sign the SPA now, it doesn’t mean you will avoid GST.
Unless the SPA you signed doesn’t have a clause that would require you to pay more than the amount you initial agreed upon. And unless the developer told you otherwise… If not, then… yeah, it’s probably true…
Which means... I'm probably not exempted from GST either. Since I signed my SPA a couple of months ago. Damn. As if the prices aren't high enough, they're making it higher. Oh joy -.-
