cessation date of an overpayment is the day prior to the date the income support pension began being paid at the correct rate. This does not automatically mean the date of the last assessment – i.e. an overpayment may have been detected, but there is no change to the current rate of pension. An example of this is when a pensioner did not advise the Department of earnings and the Department did not discover the earnings until after the pensioner had ceased work. In this case there is no reassessment of pension necessary and the overpayment is calculated for a closed period being the period of employment.
