Aaarrrgghhh*&^%!!! Do you work for the municipality by any chance?? That's a classic, stubborn bureaucratic South African attitude.
The fact is many properties were NOT liable for municipal tax before 2009, rural properties especially. There was a valuation period that started way back when, and then a phasing in period where the first year had a 75% rebate, second year a 50% rebate and by the fourth year you are paying the full amount.
People were aware this was happening, but when you were going to start being billed and for how much was the question.
The way they handled this was atrocious. I expected some sort of communication, maybe a 'welcome / this is how we will be spending your money etc.' letter/pamphlet as you do in the UK, but first communication I received from them was simply a very cryptic overdue bill – just a figure, no calculations, no explanation. The billing was so messed up the first bills never went out.
So, if you’ve been living in your home for 30 years, suddenly you find you’re customer with an overdue account.
