The ATO has published on its website a payment slip in PDF format that is to be used when taking advantage of the Commissioner’s concessional arrangements for those returns currently required to be lodged by 15 May 2007. Payment is required at the time of lodgment. The ATO says that it is not possible to supply pre-printed forms for each taxpayer. Advance payments can be made by BPAY® Direct credit, or by mail.
