What is construction and trades?
Job costing, retentions and progress claims kept straight.
Construction accounting in Australia runs on the same unit as anywhere else in the trade — the job, not the month — but the calendar, the paperwork, and the legislation around it are distinctly Australian. The financial year runs to 30 June, BAS sits on a monthly or quarterly cycle depending on turnover, and every progress claim, subcontractor payment, and retention is meant to feed a job cost ledger that ties back to the general ledger, not a spreadsheet someone updates when they remember.
Retentions — typically 5–10% withheld from each progress claim until practical completion or the end of a defects liability period — sit in their own schedule for the same reason retainage does anywhere: the money is owed and collectible, it's just not due on ordinary terms. Progress claims and the payment timeframes around them are shaped by each state's security of payment legislation (the NSW Building and Construction Industry Security of Payment Act 1999 and its equivalents elsewhere), which governs how a claim is made and disputed without changing how it's booked.

Construction and trades in Australia
AASB 15 and long-term contract revenue
Revenue on long-term construction contracts is recognised under AASB 15, generally over time as performance obligations are satisfied — the practical successor to the old percentage-of-completion approach under AASB 111. We keep cost-to-date, estimated-total-cost, and completion data current in the job cost ledger; your accountant applies the AASB 15 judgement and prepares the statements from it.
Security of payment legislation and progress claims
Each state's security of payment act (for example, the NSW Building and Construction Industry Security of Payment Act 1999) sets timeframes and mechanisms for making and disputing progress claims. We track each claim against the job cost ledger and the contract's own schedule of values; interpreting rights under the act, or handling an adjudication, is a matter for your lawyer, not a bookkeeping function.
Queensland retention trust accounts
Under the Building Industry Fairness (Security of Payment) Act 2017, retentions withheld on eligible QLD commercial construction contracts above the statutory threshold must sit in a separate retention trust account rather than general operating funds. We can flag contracts that look scheme-eligible and maintain the trust ledger and reconciliation against the trust account; whether a specific contract is actually caught by the Act is a determination for your accountant or lawyer.
Taxable Payments Annual Report (TPAR)
Businesses primarily in the building and construction industry must report payments made to contractors and subcontractors to the ATO via TPAR, due by 28 August each year. We maintain a running subcontractor payment ledger through the year so the data is ready in one place; your registered tax or BAS agent compiles and lodges the actual report.
What your registered BAS or tax agent receives from us

- Retentions receivable and payable schedule tracked to each contract's release terms and the applicable state security of payment timeframes
- Progress claim backup (schedule of values) tied line-by-line to the job cost detail behind each claim
- Subcontractor ledger with ABN status recorded and payment data staged for the annual TPAR
- Retention trust account ledger and reconciliation for QLD-scheme-eligible contracts, where flagged
