Applying for combination certificates for petroleum projects  

Combining licences avoids the need to assign costs and revenues to individual production licences.

Taxpayers can apply for a combination certificate to allow 2 or more petroleum production licences to be recognised as a single project.

This is done under the Petroleum Resource Rent Tax Assessment Act 1987.
