You will get a remittance report when payment is complete.

For information about contract management or payment, contact the relevant agency:

Department of Infrastructure, Planning and Logistics - use the email address provided in the tender documents.

If you submit your invoice by mail, you must make sure you use the correct agency billing details. Get the list of NT agency billing information (46.6 kb).

30-day payment policy

The NT Government has a 30-day payment policy for works, goods and services.

All accounts must be paid within 30 days of receiving the invoice, unless there is a dispute over the account.

Late payments

If your payment is not received within 30 days, you can apply for penalty interest payment from government if:

  • 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 2018 to 2019, the rate has been set at 1.87%.

Interest penalty rates do not apply if interest penalty payments are received late.

How to calculate penalty interest payment

Interest is calculated from the 31st day to the date the late payment was made by the government.

Example

If an invoice 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.

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.
