Understanding the Importance of Segregating Direct and Indirect Costs
One of the foundational principles of government contract accounting is segregating direct and indirect costs—and doing it correctly is critical for compliance with FAR Part 31 and DCAA audit standards.
Direct costs are those that can be clearly and exclusively attributed to a specific contract or task—such as direct labor, materials, and subcontractors. Indirect costs, on the other hand, are shared expenses that support multiple contracts or business operations. These include overhead, fringe benefits, and general and administrative (G&A) costs.
Failing to properly segregate these costs can lead to inaccurate indirect rate calculations, billing errors, audit findings, and even penalties. It may also make it impossible to justify your pricing or cost structure during proposals, evaluations, and incurred cost submissions.
To remain compliant, your accounting system must:
- Clearly distinguish between direct and indirect costs in your chart of accounts
- Allocate indirect costs using accepted methodologies
- Track job costs separately for each contract
- Exclude unallowable costs from indirect pools
