Regarding GST, yes, under the present version of the Bill (which hopefully can and will be changed) GST will apply to the buyer of the following types of property sale:
Any newly built condo, house, villa, ie. you're a developer, buy a piece of land, build homes on it, sell them. Your buyers will pay the 15% Transfer Tax AND 10% GST. Except they won't want to pay 25% tax which means they'll buy in Panama or Costa Rica instead.
Any newly remodelled house that was purchased for the purpose of remodel followed by immediate resale.
Any commercial property such as a hotel.
It's a very alarming tax which will make it almost impossible for those wanting to own their own home in Belize to justify buying a newly built home. They would be better off buying an already-lived-in home which is not taxed under this new system.
Theoretically even homes newly built by DFC will "attract" this most heinous new tax.
