A year-end compliance checklist for federal contractors covers two lists this year: the standing items that renew every year, led by SAM registration and certification maintenance, and the items that changed for 2027, including a new performance-record model on DoD contracts, documentation obligations that now follow a contract through its whole lifecycle, and a CMMC certification requirement currently on hold pending a DoD review. Working both lists in December protects eligibility before January pursuits begin.
The core of year-end compliance looks the same heading into 2027 as it did a year ago, and its items still decide eligibility before any proposal gets read.
Each item is administrative until it lapses, and then it is the reason a strong proposal never got evaluated.
The second list is what makes this year's checklist different from last year's, and three developments lead it.
The new performance-record era. Past performance information now informs decisions across the entire contract lifecycle at every agency, and the negative-event model is phasing into DoD contracts. The year-end move is gathering this year's delivery records, acceptance confirmations, and closed corrective actions while they are fresh.
Cost accounting deadlines. Contractors on cost-reimbursement or time-and-materials work whose fiscal year matches the calendar face the incurred cost submission clock, which runs six months from year-end. December is the month to confirm the books can produce what the submission requires.
CMMC is on hold, not settled. DoD had planned to make third-party Level 2 certification an award condition on most defense contracts involving controlled unclassified information starting November 10, 2026. It suspended that rollout on July 13, 2026, pending a program review, so Phase 1 self-assessment requirements stand, but the certification deadline itself isn't fixed right now. Defense-facing contractors should confirm Phase 1 status is current and stay ready to move once DoD sets a new date.
Our full breakdown of what's changing in 2027 covers the context behind each shift; this checklist is the compliance slice of it.
Sequence matters more than speed. Eligibility items come first, since a lapsed registration or expired certification stops everything else regardless of what the pipeline holds. Documentation items come second, valuable and movable, best finished while the year's details are fresh. Readiness items like CMMC status come third for defense-facing businesses, since DoD could set a new certification deadline with limited notice once its review concludes. The November check-in covers the strategic side of this review; the compliance list here is the part with hard dates attached.
USFCR has guided over 500,000 businesses since 2010, and the compliance pattern at year-end is steady: the problems that cost contractors eligibility in February were visible on a December checklist, and the businesses that worked the list on schedule entered the new year competing instead of correcting. USFCR helps contractors keep registrations, certifications, and compliance calendars current, so the standing list stays handled while attention goes to what changed.
What compliance items should federal contractors check at year-end?
Two lists: standing items that renew every year, including SAM registration status, certification expirations, accurate representations, insurance dates, and points of contact; and changed items for 2027, including the shift to lifecycle-wide use of past performance data, incurred cost submission readiness for cost-type contractors, and CMMC Phase 2's paused certification rollout for defense work involving controlled unclassified information.
What is different about compliance for 2027 compared to 2026?
Three things changed. Performance records now inform decisions across the whole contract lifecycle, with a negative-event model phasing onto DoD contracts. Documentation discipline moved from good practice to the basis of scores and rebuttals. And CMMC Phase 2, which would have made third-party Level 2 certification an award condition starting November 10, 2026, is currently paused while DoD reviews the program.
When is the incurred cost submission due?
Six months after the contractor's fiscal year-end, for businesses performing on cost-reimbursement or time-and-materials contracts. A contractor whose fiscal year matches the calendar faces a June 30 deadline, which makes December the right time to confirm the accounting system can produce the required schedules.
Does a lapsed SAM registration really stop a pursuit?
Yes. An active registration is a condition of eligibility for award and connects to payment, so a lapse takes a business out of consideration no matter how strong its proposal or past performance. Renewal dates deserve the same treatment as proposal deadlines, which is why they lead the standing list.
Print both lists and work them in order: eligibility first, documentation second, readiness third, with every item dated and owned before the holidays arrive. Pair this checklist with the November check-in for the strategic review and the 2027 changes breakdown for context. For contractors who want the standing list managed year-round, USFCR helps businesses keep registrations, certifications, and compliance calendars current, so eligibility never becomes the reason a good year stalls.
