Hi Di64
See from ATO website here:
If your business provides these services and pays contractors to deliver them, you may need to lodge a TPAR.
and:
Include payments received when employees, contractors or sub-contractors performed services on your behalf.
Are they doing the work for you, or on your behalf? TPAR applies where a business users Contractors to fulfill its obligations to its customers, not to provide services to you.
If your building needs a roof replaced and you engage Jim's Roofing to supply and install a new roof, you do not have to report payments to Jim's Roofing. If Jim's Roofing engages subcontractors to complete the task, Jim's Roofing must report these payments under TPAR.
If in doubt, consult with your tax adviser, not acquaintances at the pub. (or on a forum:)
Regards
Gavin
