Construction: project costing and cross-region tax

Project-based costing is the foundation; cross-region prepayment and workforce compliance are where firms trip.

Industry characteristics

  • Work is organised by project, so costs must be aggregated by project;
  • Cross-region operations involve prepayment and registration obligations;
  • Workforce arrangements vary — crews, labour services and subcontracting coexist.

Key exposures

  • Project costs merged together, so no single project's real result is visible;
  • Cross-region formalities not completed in time, creating filing and registration risk;
  • Non-standard employment and settlement arrangements, with no link between documents and people;
  • Unclear compliance boundaries around qualification use and project contracting.

How we work

  1. Create a separate accounting unit per project, keeping cost, revenue and funds in one file;
  2. Build a checklist of cross-region tax obligations with deadlines and owners;
  3. Standardise employment settlement and documentation so transactions, people and invoices line up;
  4. Set out the compliance boundaries for qualification use and project contracting, flagging what cannot be crossed.
