Government Contractor Year-End Close: ICS Prep Guide

The government contractor year-end close is not a bookkeeping exercise. It is the opening phase of your incurred cost submission. Every adjusting entry, rate pool reconciliation and cost reclassification recorded between December and February decides whether the ICS filed six months later holds up under DCAA review.

The failure mode is predictable. Books close on 31 December, the ICS goes in the following June, and an inadequacy determination comes back months later. By then the fiscal year is long shut and the entry that caused it is nine months old.

The year-end close errors that produce ICS inadequacy determinations are rarely exotic. They are ordinary adjusting entries recorded in December or January and never revisited: a bonus accrual coded to the wrong pool, a subcontractor accrual that was never reversed, or an executive compensation amount that was never tested against the FAR cap.

The problem is rarely the ICS schedules. It is a misclassification sitting in an indirect pool that traces back to a year-end adjusting entry. A bonus recorded as indirect labor that should have been split between allowable compensation and unallowable cost under FAR 31.205-6(p) does not stay contained. One entry of that kind restates Schedule B, Schedule H, and every contract-level billing reconciliation in the submission.

Six months is not a generous timeline. It is a tight one. Design the close to produce ICS-ready data from the first adjusting entry, and treat the close and the GovCon year-end close package as one workflow rather than two projects with a six-month gap between them.

Most of the work that decides the outcome happens in Q4, before the year has even ended.

What Makes the Government Contractor Year-End Close Different From a Standard Close?

Government contractor year-end close requires every step a commercial close requires (accruals, deferrals, reconciliations, trial balance validation) plus a second layer of GovCon-specific procedures that standard accounting practices do not address. The FAR cost principles [FAR Part 31], CAS requirements, and the FAR 52.216-7 allowable cost and payment clause impose obligations with no commercial equivalent. Ignoring this second layer produces financial statements that look correct to a CPA but fail a DCAA audit.

The core difference: a commercial year-end close produces financial statements. A government contractor year-end close produces financial statements and the validated cost data feeding your ICS schedules. Those ICS schedules determine your final indirect rates, which determine how much the government owes you (or how much you owe back) on every cost-reimbursable contract performed during the fiscal year.

An overhead rate variance of three points between provisional and final rates does not apply to contract value. It applies to the allocation base. On $2M of direct labor charged to a cost-plus-fixed-fee contract, three points is a $60,000 settlement adjustment. Multiply that across three or four contracts and the number gets serious. The year-end close is where you control the accuracy of that settlement.

Month-by-Month Timeline: Fiscal Year End to ICS Filing

Contractors with a December 31 government contractor fiscal year end have 181 days between closing their books and the ICS deadline on June 30, and 182 in a leap year. This timeline maps the critical activities for each phase. Contractors with a September 30 fiscal year end follow the same sequence, shifted to October through March.

Pre-Close: October Through November (Before Year End)

1. Run preliminary indirect rate calculations. Compare year-to-date actual rates against provisional billing rates. A significant variance between year-to-date actual rates and provisional billing rates, commonly considered material at 10% or more, warrants requesting a billing rate adjustment under FAR 42.704(c) (Overhaul 42.504(c), which is where this subpart now sits) before year end.
2. Reconcile subcontractor costs. Contact all subcontractors and request final invoicing for work performed through year end. Subcontractor accruals are one of the most common sources of ICS inadequacy findings.
3. Review cost classifications. Run a report of all costs charged to indirect pools and confirm each cost element is in the correct pool and classified as allowable or unallowable per FAR 31.205.
4. Validate timekeeping records. Confirm all labor distribution reports reconcile to payroll. DCAA tests timekeeping through floor checks, and labor is the area where a reconciliation gap is hardest to explain after the fact. Discrepancies found after close are expensive to correct.

Close Period: December Through January

1. Record all adjusting entries. Accruals for incurred-but-not-invoiced expenses, prepaid expense amortization, depreciation, accrued vacation, and bonus accruals. Each entry must reference the supporting documentation.
2. Segregate unallowable costs. FAR 31.201-6 requires contractors to identify and exclude unallowable costs from any billing, claim, or proposal. This is not optional. Every cost in your indirect pools must be screened against the FAR 31.205 cost principles.
3. Reconcile each indirect rate pool. Tie every dollar in fringe, overhead, and G&A pools back to the general ledger trial balance. The pool totals become Schedule B, C, and D inputs for the ICS.
4. Lock the general ledger. Once all adjusting entries are posted and reviewed, close the fiscal year in your accounting system. No entries should post to the closed year after this point without documented management approval.

ICS Preparation: February Through April

1. Build ICS schedules from the closed trial balance. Schedule A (indirect rate summary), Schedules B/C/D (indirect cost pools), Schedule H (direct costs by contract with applied rates), and Schedule I (cumulative billed versus incurred). Every number traces to the locked trial balance.
2. Reconcile total costs claimed against the trial balance. The total incurred costs across all ICS schedules must equal the total costs in your audited trial balance. A $1 discrepancy triggers an inadequacy finding.
3. Prepare the certificate of final indirect costs. The certificate is item (N) on the adequacy checklist at FAR 52.216-7(d)(2)(iii), and the certificate itself is the clause at FAR 52.242-4, Certification of Final Indirect Costs. The policy sits at FAR 42.703-2 (Overhaul 42.503-2), which implements 10 U.S.C. 3747 and 41 U.S.C. 4307: a proposal is not accepted and no final rate agreement is made unless the costs have been certified. Do not skip it on the theory that unsigned is safer than wrong. Under FAR 42.703-2(c), if you fail to certify and no waiver applies, the contracting officer establishes the rates unilaterally. False certification carries penalties under the False Claims Act.

Submission: May Through June

1. Complete the ICS package. Compile all schedules, the certification, supporting schedules for executive compensation reasonableness, and the reconciliation to audited financials.
2. Submit to your cognizant DCAA office by the deadline. For December 31 fiscal year end, the deadline is June 30. Submit electronically using DCAA’s Incurred Cost Electronically (ICE) tool or a format your cognizant auditor accepts.
3. Retain all workpapers and supporting documentation. DCAA commonly audits ICS submissions years after filing, not months. The adjusting entries, reconciliations, and pool detail from your year-end close are the primary evidence base.

GovCon-Specific Adjusting Entries That Drive ICS Accuracy

Standard year-end adjusting entries (accruals, deferrals, depreciation) apply to government contractors the same way they apply to commercial companies. The difference is a set of adjusting entries unique to the GovCon operating model. Missing any of these entries produces ICS schedules with inaccurate pool totals, misallocated costs, or unidentified unallowable charges. DCAA flags all of them.

Unallowable Cost Reclassification

FAR 31.201-6(a) requires costs “expressly unallowable or mutually agreed to be unallowable” to be identified and excluded from any billing, claim or proposal. The same paragraph carries a trap most close checklists miss: directly associated costs, meaning any cost generated solely as a result of incurring an unallowable cost, are unallowable too. The airfare to the lobbying event follows the lobbying.

During year-end close, every cost in your indirect pools must be reviewed against the FAR 31.205 catalog. Entertainment [FAR 31.205-14], alcoholic beverages [FAR 31.205-51], and fines and penalties [FAR 31.205-15] are common examples. Reclassify these from the indirect pool to a segregated unallowable account. The unallowable totals carry to Schedule L of the ICS.

Executive Compensation Caps

Compensation above the statutory benchmark is unallowable under FAR 31.205-6(p). The cap is not a DCAA number: it is the benchmark compensation amount determined by the Office of Federal Procurement Policy under 41 U.S.C. 1127, adjusted annually.

Use the figure for the fiscal year you are closing, and confirm it before you test anything. Applying last year’s cap is itself the error, and a cap figure copied from an article is exactly how that happens. We are not printing a number here for that reason.

Check which version of the rule your contract sits under. FAR 31.205-6(p) turns on the contract award date. Contracts awarded on or after 24 June 2014 are covered under (p)(4) and the cap reaches all employees. Older awards reach senior executives only, and for DoD, NASA and the Coast Guard the all-employee rule starts at 31 December 2011. “Compensation” is defined broadly at (p)(1)(i): wages, salary, bonuses, deferred compensation and employer contributions to defined contribution pension plans, whether paid, earned or accruing.

During close, compare each executive’s total compensation against the cap for that year. The excess requires a journal entry reclassifying it from the indirect pool to unallowable. Schedule J of the ICS specifically addresses executive compensation.

Provisional-to-Actual Rate Variance

Throughout the year, you billed the government using provisional indirect rates. Year-end actuals will differ. Record the cumulative variance between provisional billings and actual incurred costs as an adjusting entry. This entry feeds directly into Schedule I, which reconciles billed amounts against incurred costs by contract. An unrecorded variance here means Schedule I will not tie to your general ledger, an automatic inadequacy trigger.

Subcontractor Cost Accruals

Subcontractors who performed work before fiscal year end but have not yet invoiced create an accrual requirement. Estimate the uninvoiced amounts based on purchase orders, delivery reports, or subcontractor correspondence. Record the accrual in the appropriate cost pool or direct cost account. DCAA checks whether your direct costs by contract (Schedule H) include all incurred subcontractor costs, not only those invoiced and paid.

What Is Indirect Rate Pool Reconciliation and Why Does It Drive ICS Accuracy?

Indirect rate pool reconciliation is the single most important year-end close activity for ICS preparation. Every ICS schedule containing indirect costs depends on accurate, reconciled pool totals. A cost misclassified between overhead and G&A changes both rates. A cost left in the wrong pool inflates one rate and deflates another. Both errors cascade across every contract-level billing calculation in the submission.

The reconciliation process follows three steps for each pool (fringe, overhead, G&A):

1. Tie the pool total to the general ledger. Export every account assigned to the pool. Sum them. Compare the total against the pool total in your rate calculation. The numbers must match to the penny.
2. Verify each cost element’s pool assignment. Rent belongs in overhead, not G&A. Health insurance belongs in fringe, not overhead. Executive salaries belong in G&A, not overhead. Misassignments between pools are a recurring audit finding on ICS reviews, and they are cheap to catch at close and expensive to unwind afterwards.
3. Confirm the allocation base. Fringe and overhead typically allocate over direct labor dollars. G&A allocates over total cost input. Verify the base calculation matches your disclosed practices in your CAS Disclosure Statement (if applicable) or your established and consistently applied accounting practices.

Use the Amerifusion indirect rate calculator to model your actual year-end rates against your provisional billing rates. A variance of more than a few points on any single pool warrants a detailed review of cost assignments within that pool before building ICS schedules. That trigger is our practice, not a regulatory threshold, and so is the 10% figure above.

5 Year-End Close Mistakes That Create ICS Problems

These five mistakes appear repeatedly in DCAA inadequacy determinations traced back to the year-end close ICS preparation process. Each mistake is preventable during close. Each becomes expensive to fix after the ICS is submitted.

1. Closing the Books Before Subcontractor Costs Are Reconciled

A government contractor closes their fiscal year on December 31 and locks the general ledger on January 15. A subcontractor invoice for $74,000 in December work arrives on February 3. The cost belongs in the prior fiscal year but the ledger is locked. Recording it in the current year misallocates the cost between fiscal years, distorts both years’ indirect rates, and creates a mismatch between Schedule H (direct costs by contract) and the trial balance. Accrue subcontractor costs in the final quarter. Do not wait for invoices.

2. Failing to Reverse Prior-Year Accruals

Accruals recorded at the end of the prior fiscal year must be reversed in the opening period of the new year. Unreversed accruals double-count expenses: once in the prior year (as the accrual) and again in the current year (when the actual invoice is paid). For government contractors, double-counted costs inflate indirect pools, which inflates indirect rates, which inflates billings to the government. DCAA considers overbillings caused by unreversed accruals the same as any other overbilling: questioned costs subject to refund.

3. Leaving Unallowable Costs in Indirect Pools

Every holiday party, alcohol purchase, country club membership, and lobbying expense must be reclassified from indirect pools to the segregated unallowable account during close. FAR 31.201-6 requires that unallowable costs be identified and excluded before any billing, claim, or proposal. DCAA expects identification as close to the time of incurrence as possible, and waiting until ICS preparation creates exposure if costs were billed before segregation.

Costs discovered in pools during an ICS audit carry a penalty on top of the disallowance, and the trigger is not what most summaries say. The penalty equals the disallowed costs, plus interest on any paid portion, when the cost is expressly unallowable under a cost principle [FAR 42.709-2(a)(1); Overhaul 42.508-2]. It doubles when the cost had already been determined unallowable for that contractor before the proposal was submitted [42.709-2(a)(2)]. Certifying the proposal is not the trigger for the single penalty.

There is a size threshold worth knowing. These penalties apply to contracts in excess of $1 million, excluding fixed-price contracts without cost incentives and firm-fixed-price commercial contracts [FAR 42.709-1(b)]. Below that, the disallowance still stands; the statutory penalty does not attach.

4. Inconsistent Allocation Base Calculations

A contractor uses direct labor dollars as the overhead allocation base all year, then switches to total labor dollars (direct plus indirect) in the year-end rate calculation.

For fully CAS-covered contractors, this inconsistency violates CAS 418 (Allocation of Direct and Indirect Costs). For contractors not subject to full CAS coverage, FAR 31.203(c) requires indirect costs to be accumulated by logical cost groupings, with a base that allocates each grouping on the basis of the benefits accruing. The rule that actually bites here is elsewhere in the same section: 31.203(d) bars fragmenting a base once it has been accepted, and 31.203(e) is what permits a change of method, and only when there is a significant change in the nature of the business.

Either way, DCAA compares your current-year allocation bases against your prior-year submission. Any unexplained change triggers a full cost impact analysis. Maintain the same allocation bases year over year unless you formally revise your accounting practices with notice to the ACO (Administrative Contracting Officer).

5. Not Reconciling the ICS to the Audited Trial Balance

The total incurred costs in the ICS must reconcile to the total costs in the fiscal year trial balance. This seems obvious, and it is still one of the most common ways a submission fails adequacy review. The root cause is usually timing differences: adjusting entries posted after the trial balance was pulled for ICS preparation but before the financial statements were finalized. Lock the trial balance first. Build ICS schedules from the locked version. Do not revise the trial balance after ICS preparation begins.

Frequently Asked Questions

Key Takeaways

• Year-end close and ICS preparation are one workflow, not two. Every adjusting entry and rate pool reconciliation during close produces data the ICS schedules consume. Treating them as separate projects creates gaps, rework, and avoidable DCAA findings.
• Start the process in Q4, before the fiscal year ends. Pre-close activities (preliminary rate calculations, subcontractor reconciliation, cost classification review) reduce the post-close workload and catch problems while corrections are inexpensive.
• Segregate unallowable costs during close, not during ICS prep. FAR 31.201-6 requires identification before any billing or claim. Costs left in pools that DCAA discovers carry penalty exposure under FAR 42.709-2 (Overhaul 42.508-2) in addition to the disallowance itself, on contracts over $1 million.
• Reconcile your ICS to the locked trial balance and do not revise either independently. The total incurred costs in the ICS must equal the total costs in the trial balance. Timing differences between trial balance adjustments and ICS preparation are a top cause of inadequacy determinations.
• The 6-month ICS deadline is a ceiling, not a target. Contractors who close efficiently and begin schedule preparation in February routinely submit by April or May, leaving buffer for review cycles and corrections.

Build a Year-End Close Process That Feeds a Clean ICS

The government contractor year-end close determines the quality of every financial deliverable that follows: your ICS, your final indirect rates, and the settlement on every cost-reimbursable contract you performed during the fiscal year. A disciplined close process, starting in Q4 and running through a locked trial balance, eliminates the scramble that produces ICS deficiencies and audit findings.

Take the Compliance Readiness Check to identify gaps in your year-end close procedures. Use the indirect rate calculator to compare your provisional rates against year-to-date actuals before you finalize adjusting entries.
