Long Term
Construction Contracts

The ATO has specific views on income recognition in long-term construction contracts — requiring income to be recognised on a stage-of-completion basis across multiple income years, not deferred until project completion.

TR 2018/3 — Stage of Completion

Income recognition in
long-term construction


A long-term construction contract is a contract spanning more than one income year. The ATO has published guidance — particularly Taxation Ruling TR 2018/3 — requiring that income from such contracts be recognised progressively on a stage-of-completion basis, not deferred until project completion.

This means builders and developers working on multi-year projects must assess the stage of completion at each income year end (30 June) and include the corresponding portion of the total contract price in assessable income — regardless of when cash is received.

  • Income must be recognised progressively — TR 2018/3 is the governing ATO ruling
  • The “expected outcome” method requires estimation of total contract profit at each year end
  • Where the outcome cannot be reliably estimated — recognise recoverable costs only
  • Progress claims received do not determine the amount recognised — the stage of completion drives income
  • Loss contracts — losses may need to be recognised in the year they become foreseeable
  • ATO audit programs specifically target long-term construction contracts in residential and commercial developments
  • Records of stage-of-completion at each 30 June must be maintained and be capable of ATO scrutiny

MGS Private’s Assistance

Compliance advice and audit representation

Year-End Stage Assessment
At each 30 June, the developer’s accountant must determine the stage of completion and calculate assessable income accordingly. MGS Private advises on the methodology and whether TR 2018/3 applies to each specific contract arrangement.
Method Selection
The stage-of-completion can be assessed using the cost method (costs incurred as a proportion of total expected costs), the engineer’s method, or the completed units method — each giving different results. MGS Private advises on which method is appropriate and defensible for each development.
ATO Audit Response
The ATO specifically targets long-term construction contract income recognition — claiming developers have deferred income by treating contracts as completed at settlement rather than on a stage-of-completion basis. MGS Private represents clients through these audits from first contact to resolution.
Private Ruling Applications
Where the income recognition treatment of a specific contract is uncertain, a private ruling application to the ATO can provide certainty before the year-end determination is made — protecting the developer’s position from audit.
