Interest we charge

We apply interest charges to ensure that taxpayers who underpay their tax don't receive an advantage over those who pay on time. These interest charges also compensate the community for the impact of late payments.

The law provides us with the discretionary power to remit (partially or in full) interest charges in certain circumstances.
