FedRAMP 20x is here. With it comes a new set of deadlines and requirements that cloud service providers, assessors, and agencies need to understand.
If you’re trying to figure out when you need to comply, what “CR26” actually means, and how to prepare, this guide breaks down everything you need to know about the 2026 FedRAMP deadlines.
What is CR26?
CR26 stands for “Consolidated Rules 2026.” It’s the FedRAMP PMO’s term for the comprehensive, unified set of rules that will govern both Legacy Rev 5 and FedRAMP 20x moving forward.
Instead of scattered guidance documents, RFCs, and piecemeal updates, CR26 consolidates everything into one stable baseline.
Think of it as the FedRAMP PMO finally saying: “Here are the rules. All of them. In one place. And they’re not changing for a while.”

Key CR26 Dates You Need to Know
May 2026: CR26 Rules Finalized
The PMO plans to release the finalized Consolidated Rules in May 2026. This includes updated Legacy Rev 5 requirements alongside the finalized 20x rules for both Class B and Class C baselines.
Late 2026: Adoption Window Closes
Once CR26 is finalized, organizations will have a window to adopt the new rules. This window closes late in the year, after which the new baseline becomes the standard.
2028-2029: Stability Period Ends
The PMO intends for the CR26 baseline to remain stable for two and a half years after finalization. That means you can plan your compliance roadmap without worrying about the rules shifting dramatically every few months.

Why Does CR26 Matter for Your Organization?
If you’re a cloud service provider (CSP) currently pursuing or maintaining FedRAMP authorization, CR26 affects you no matter which track you’re on:
If You’re on Legacy Rev 5
CR26 includes updated requirements for Legacy Rev 5 organizations. You’ll need to understand what’s changing and how it affects your existing System Security Plan and ongoing continuous monitoring obligations.
If You’re Pursuing 20x Class B or C
CR26 finalizes the rules for both 20x Class B and Class C baselines. If you’ve been operating under draft or pilot guidance, CR26 gives you the finalized version to build toward.

If You Haven’t Started Yet
This is actually a great time to begin. With CR26 providing a stable, predictable baseline, you can build your compliance program without the fear that the requirements will shift underneath you before you’re even authorized.
How to Prepare for CR26
1. Audit Your Current Documentation
Whether you’re on Legacy Rev 5 or pursuing 20x, take stock of your current documentation. Manual, Word-based SSPs are becoming a liability as the PMO pushes toward machine-readable formats.
→ Learn why manual SSP templates are falling behind
2. Understand Key Security Indicators (KSIs)
20x replaces traditional narrative controls with KSIs — specific, verifiable data points that prove your security posture rather than just describing it.
→ See how KSIs compare to traditional controls
3. Move Toward Machine-Readable Data
The direction is clear: FedRAMP wants OSCAL-formatted, machine-readable documentation. The Security Decision Record (SDR) is replacing the traditional SSP as the format of choice for the future.
→ Learn more about machine-readable OSCAL documentation
4. Get Ahead of the Adoption Window
Don’t wait until the CR26 adoption window is closing to start your transition. Organizations that prepare early will have a significant advantage over those scrambling at the deadline.

What Happens if You Miss the Deadlines?
While the PMO hasn’t published harsh penalties for organizations that don’t immediately adopt CR26, missing the transition window means:
- Slower authorization: You may be stuck working under outdated guidance while others move faster with the new, streamlined rules.
- Competitive disadvantage: Agencies increasingly favor CSPs who demonstrate modern, automated compliance capabilities.
- More work later: Eventually you’ll need to transition anyway, and doing it under time pressure is more expensive and error-prone than doing it proactively.
