We used to have the 10% discount and then resolved (by special resolution) to rescind it. The discount had been suggested by our then strata managers who were not very good and used it to promote themselves, i.e. we can get you a discount on the levies. This is misleading.
It is my understanding that you don't require a by-law, the legislation just requires a special resolution that operates until it is rescinded. If a by-law were required the legislation would say so.
There were a number of reasons why we rescinded the discount but these are/were some of the considerations:
1. the benefit is illusory. If you have a budget of $100,000 for the coming year, i.e. that is how much money you will need, then you have to then factor in the effect of the discount. If everyone pays prior to the due date, you will be $10,000 short on the budget so you will have take that into account in setting the budget and increase the budget to $110,000. Effectively then, there is no discount.
2. a discount has little or no effect in making people pay on time. People who don't pay on time are not going to change their ways because of a 10% discount.
3. conversely, a discount for those who pay prior to the due date unfairly benefits those owners, as owners who pay on or after the due date are then subsidising the former. Why should someone who pays one day before the due date receive a discount, when a person who pays on the due date or even one or two days or a couple of weeks later does not?
Bear in mind that the standard 10% interest charge does not apply to levies until one month after the due date, i.e. you have one month to pay.
More generally – I am in a small strata where overall we don't have that much of a problem with levy payments. There is one owner who habitually falls behind, sometimes for more than a year, but they always pay – eventually. Our view is that as they are paying 10% we are getting a better return on the money than we would if it were invested. Obviously circumstances differ from strata to strata, and if you are in a larger complex where half or more are behind on payments that would be a nightmare, but a discount is not going to change anything.
