Ah, thank you, I totally missed that option.
One more question; assuming that I want to pay 100% of the liability for 2009 as preliminary tax for 2010, should I simply pay the final liability, or do I need to take into account the changes to the income levy?
That is, say, assuming a liability of 5000 for 2009, should the preliminary tax for 2010 just be 5000, or should it be (5000 / 101.67) * 102 = 5016, that is, the liability with the old income levy removed and the new one applied? Or something else entirely?
