Let us take the case of an ordinary person like myself, like all of us. I have to complete an income tax return every year. I do that , I receive what is called a notice of assessment, which shows me that I paid everything that I was supposed to. Six months later, I get a new amended notice of assessment which states that my file has been audited and that I had neglected to pay $1,284.32. I'm giving you a hypothetical case here that is not my own; I hope you will not be calling me up tomorrow morning.
