For government contractors, maintaining a rigorous audit trail is not merely a best practice; it is a regulatory requirement. Among the most critical financial documents in your accounting system is the Labor Distribution Report (LDR). Whether you are a small business navigating your first DCAA (Defense Contract Audit Agency) audit or an established firm managing multiple task orders, the LDR serves as the bridge between your payroll system and your project accounting.
Definition of an LDR
A Labor Distribution Report is a financial document that reconciles an organization’s total payroll expenses with the specific projects, contracts, or indirect cost pools where those hours were performed. It acts as a granular ledger, documenting exactly how much of an employee’s gross pay—including fringe benefits and overhead allocations—is charged to specific government contract line items (CLINs) versus internal overhead or G&A (General and Administrative) accounts.
Under FAR Part 31 (Contract Cost Principles and Procedures), contractors must maintain adequate records to substantiate that costs charged to a contract are allowable, allocable, and reasonable. The LDR is the primary evidence used to prove that labor costs were distributed in accordance with the employee’s timecard and the company’s established accounting policies.
Why the LDR Matters for Compliance
The LDR is essential for three primary reasons:
- DCAA Compliance: During an accounting system audit, auditors will trace costs from the general ledger to the LDR, and finally to the individual timecards. Discrepancies here are a major red flag that can lead to an "inadequate" accounting system determination.
- Invoicing Accuracy: When submitting a Public Voucher (SF 1034) for cost-reimbursement contracts, your billed amounts must match the LDR. Using SamSearch to track your contract performance and billing cycles helps ensure your internal reporting aligns with agency expectations.
- Indirect Rate Management: The LDR helps contractors calculate their actual indirect rates by identifying the ratio of direct labor hours to indirect labor hours, which is vital for year-end rate adjustments.
Examples of LDR Usage
- Project Cost Tracking: A software engineering firm working on a Cost-Plus-Fixed-Fee (CPFF) contract uses the LDR to ensure that a developer’s 160 hours for the month are split 80% to Project A and 20% to Project B, matching the approved timecards.
- Audit Defense: If a contracting officer questions a spike in labor costs on a specific task order, the contractor produces the LDR to show the specific employees, their hourly rates, and the exact pay periods where the surge occurred.
Frequently Asked Questions
What is the difference between a timecard and an LDR?
A timecard is the source document created by the employee to record hours. The LDR is the accounting report generated by the finance department that converts those hours into dollar amounts based on the employee's compensation rate and the company's cost accounting structure.
How often should I generate an LDR?
Best practice dictates that LDRs should be generated at the end of every payroll period. This allows for timely reconciliation and ensures that your monthly billing to the government is accurate and defensible.
Can I use spreadsheets to manage my LDR?
While small businesses often start with Excel, manual spreadsheets are prone to human error. DCAA auditors prefer integrated accounting systems (like Deltek Costpoint or Unanet) that automatically generate LDRs directly from timekeeping data to prevent manual manipulation.
What happens if my LDR does not match my payroll register?
This is a critical failure. Your payroll register (total cash paid) must equal your total labor distribution (total costs allocated to projects + indirect pools). If they do not match, you have an unrecorded cost or a misallocation, which must be corrected via a journal entry before submitting your next invoice.
Conclusion
The Labor Distribution Report is the backbone of your contract accounting. By ensuring your LDR is accurate, consistent, and reconciled against your payroll, you protect your company from audit findings and maintain the financial integrity required to win and retain federal contracts.
