A DCAA-derived term — not found in the FAR itself, but used extensively in the DCAA Contract Audit Manual (Chapter 6), the standard Incurred Cost Audit Program, and the ICE model. The FAR’s own term is “final indirect cost rate proposal.”
The label DCAA uses for the package itself — the Incurred Cost Submission Adequacy Checklist is named after it. Inside that checklist and the Contract Audit Manual, DCAA uses “incurred cost proposal” interchangeably to refer to the same deliverable.
Emphasizes the electronic filing format — usually the completed DCAA ICE Model workbook transmitted by email or agency portal.
The exact term used in FAR 52.216-7(d)(2)(i), which requires the contractor to submit an adequate final indirect cost rate proposal to the Contracting Officer (or cognizant Federal agency official) and auditor within the six-month period following the expiration of each of its fiscal years. This is the regulatory anchor every other label points back to — ICP, ICS, ICE, FIRP, and ICRP all describe the same FICRP package.
Do not let the terminology trip you up. If a Contracting Officer, DCAA auditor, or consultant references any of the terms above — they mean the same annual package: schedules, reconciliations, and supporting data that true up your indirect rates for a single fiscal year.
Costs invoiced during the year using estimated (provisional) rates approved at contract start per FAR 42.704.
Costs computed from the closed-book general ledger after fiscal year-end. These are the final indirect rates for that FY. (FAR 42.705)
Overbillings (you invoiced too much) are credited back to the government. Underbillings (you invoiced too little) may be invoiced up to the contract funding limit. That reconciliation — at the contract level — is the purpose of the ICS.
Provisional rates are a guess you live on during the year. Actual rates are the truth you compute after the year closes. The ICS exists so the government gets paid on truth, not on guesses.
Books close. Trial balance reconciled. General ledger locked for the year.
GL extracted, payroll reconciled, contract data compiled, unallowables screened.
Schedules A–O prepared; executive comp analyzed; adequacy walkthrough completed.
Package submitted to DCAA cognizant office. Calendar-year contractor? Due June 30.
Failing to submit on time can trigger the DCAA adequacy process on an unfavorable footing, delay contract closeout, block release of retentions, and create exposure under FAR 42.709 for unallowable costs discovered in any later-submitted package. The ACO may also impose unilateral final rates if the contractor remains non-compliant.
