Scheme guidance - Interest rate for late compensation payments for permanent impairment
To provide decision makers with scheme guidance on the interest rate to be applied to permanent impairment entitlements which are not paid within the specified period under section 26 of the Safety, Rehabilitation and Compensation Act 1988 (SRC Act).
Sections 24 and 25 of the SRC Act provide for lump sum payments to employees for injuries which result in permanent impairment. Provision exists under section 26 of the SRC Act for payment of interest to an employee if a permanent impairment lump sum payment is not made to the employee within 30 days after the date of assessment letter.
Up until 24 June 2003, the rate of interest was:
the weighted average yield derived from the Treasury note tender for 90 day notes settled immediately prior to the last day of the thirty day settlement period.
However, the Reserve Bank of Australia (RBA) ceased to provide regular 90 day Treasury note tenders and, on the 25 June 2003, the rate was revised in a Ministerial Notice of Declaration to:
the weighted average yield of 90 day bank-accepted bills, as published by the Reserve Bank of Australia, settled immediately prior to the last day of the thirty day settlement period.
This specified rate has been retained in the two revised legislative instruments that have subsequently been issued.
With effect from 25 June 2003, calculation of interest payable under subsection 26(3) should be made using the weighted average yield derived from 90 day bank-accepted bills settled immediately prior to the last day of the thirty day settlement period for payment of permanent impairment amounts.
The reference to ‘settled immediately prior to the last day of the thirty-day settlement period’ refers to the weighted average yield settled on the 29th day after the date of assessment, which is published by the RBA on the following day. Where an interest rate has not been settled by the RBA on the 29th day, the applicable interest rate is the last previous interest rate settled before the 29th day.
Interest is payable for the period from the 31st day to the day on which the amount is paid.
The rate is available from the RBA website. On the RBA home page select Market Operations, then select the Statistics tab and click on Interest Rates. Select Interest Rates and Yields – Money Market – Daily.
There are limited circumstances where the interest payable to an employee under section 26(2) of the SRC Act does not apply. These include:
- where there has been a request for reconsideration on the determination (section 26(4)(a))
- where there is a proceeding in respect of the determination before the AAT (section 26(4)(b))
- where the payment has been delayed due to compliance with the Health and Other Services (Compensation) Act 1995 (HOSC Act).
A decision not to pay interest under section 26 is not a determination under the Act and is not subject to the reconsideration process.
The following calculations should be used by claims managers when assessing the amount of interest payable:
- applicable RBA interest rate ÷ 100 = interest rate percentage
- interest rate percentage x section 24 award amount = yearly amount
- yearly amount ÷ 365 = daily amount
- daily amount x number of days late = amount payable.
An employee has an accepted claim for an injury resulting in permanent impairment. The section 24 permanent impairment amount was assessed as $12,706 on 11 December 2018, however was not paid until 27 June 2019, 168 days after the 30 day timeframe expired. The applicable interest rate 29 days after the date of assessment is 2.05%, that being the rate set by the RBA for the 9 January 2019, but not published by the RBA until 10 January 2019.
In this scenario, the interest payable under section 26 of the SRC Act would be calculated as follows:
- 2.05 ÷ 100 = 0.0205 (interest rate percentage)
- 0.0205 x $12,706 = $260.473 (yearly amount)
- $260.473 ÷ 365 = 0.713624657 (daily amount)
- $0.713624657 x 168 = $119.89 (amount payable).
