5 Reasons Government Contractors Need DCAA-Aware Accounting A clean set of books that would make any small-business CPA proud can still fail a federal audit cold. That is the trap of government contractor accounting. DCAA — the Defense Contract Audit Agency — does not grade your books on whether they balance. It grades them on whether your costs are sorted, tracked, and documented the exact way the Federal Acquisition Regulation requires. A generalist firm can do everything "right" by GAAP standards and still leave you exposed to a finding, a payback, or a contract you suddenly can't keep. Here are five reasons why a contractor with cost-reimbursable or time-and-materials work needs DCAA-aware accounting from day one — and why the firm doing your taxes probably isn't built for it. 1. DCAA wants your costs segregated three ways, and QuickBooks-out-of-the-box won't do it The foundation of DCAA-compliant accounting is a job-cost system that segregates costs into three buckets: direct, indirect, and unallowable. Direct costs are charged to a specific contract. Indirect costs — rent, admin salaries, the office coffee — get pooled and allocated across contracts. Unallowable costs (more on those in a minute) get walled off entirely so they never touch a government invoice. A standard accounting setup lumps these together because, for a commercial business, it doesn't matter. For a GovCon, it is the whole game. If your chart of accounts can't show direct, indirect, and unallowable as distinct, auditable streams, you don't have a non-compliant system — you have no system, as far as DCAA is concerned. The fix is structural, not cosmetic. It means a chart of accounts and a cost-accumulation structure built around the contract from the start. 2. Your indirect cost rates have to be calculated, not guessed — or you'll be writing the government a check This is where government contractor accounting DCAA rules turn into real money. When you bid a cost-reimbursable contract, you bill the government at provisional indirect rates — your vetted estimate of overhead and G&A as a percentage of direct cost. At year end, you calculate your actual rates. If you billed at a higher rate than you actually incurred, you owe the difference back. Here's the math. Say you bill $1.2M of direct labor in a year at a provisional overhead rate of 60%. That's $720,000 of overhead billed. If your actual overhead rate comes in at 48%, your true recoverable overhead was $576,000 — and you just over-billed the government by $144,000 that you have to return. A firm that doesn't track indirect...
