You will get a remittance report when payment is complete.

All invoices under $1 million will be paid within 20 days of receiving the invoice, unless there is a dispute over the account.

All invoices over $1 million will be paid within 30 days of receiving the invoice, unless there is a dispute over the account.

You can seek penalty interest payments from government if these payment terms aren't met.

Late payments

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 2019 to 2020, the rate has been set at 1.39%.

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.

Example

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.

Invoice received

15 April

30 day payment due

14 May

Payment made

31 May

Penalty period begins

15 May

Penalty period ends

31 May

How to claim penalty interest payment

You will need to submit a tax invoice to claim the penalty interest within 90 days of the late payment being made.

You must submit your invoice to the government organisation that received the original invoice.

Invoice details must include the following details:

  • date the NT Government organisation received the original invoice
  • date of payment
  • copy of the original invoice
  • period for which the supplier considers interest is due
  • amount of penalty interest sought.
