You can seek penalty interest payments from government if these payment terms aren't met.
The invoice payment period applies from the date of receipt of the invoice where:
- the invoice is correct and not disputed
- works, goods or services have been received.
Penalty interest rates
The penalty interest rate is set on an annual basis and paid at the 90 day bank bill rate as at 1 June each year.
For 2020 to 2021, the rate has been set at 0.093%.
Penalty interest rates do not apply if interest penalty payments are received late.
Penalty interest claims are not subject to GST.
How to calculate penalty interest payment
Interest is calculated from the 21st or 31st day, depending on the invoice amount, to the date the late payment was made by the government.
If an invoice of more than $1 million is received on 15 April and payment is made on 31 May, interest is payable is for the period 15 May to 31 May (both days inclusive) or 17 days.
