Understanding FAR & DFARS: A Complete Guide for Government Contractors
Unlock the essentials of FAR and DFARS to stay compliant and competitive in government contracting. Read the full guide now to strengthen your strategy.

Navigating government contracts can be challenging, especially when it comes to understanding the regulations that govern them. For government contractors, two essential regulatory frameworks to understand are FAR and DFAR.
Whether you're a seasoned contractor or new to the industry, understanding FAR and DFAR is vital for maintaining compliance and managing contracts effectively. Staying current with these regulations keeps your organization audit-ready and positioned for success in the federal marketplace.
What are FAR and DFARS?
The Federal Acquisition Regulation (FAR) is the primary set of rules governing federal procurement processes. It applies across all federal agencies and outlines the regulations contractors must follow when providing goods or services to the government. For more on the role of FAR in compliance, check out Unanet's DCAA Compliance Guide.
DFARS, or the Defense Federal Acquisition Regulation Supplement, builds on FAR and applies specifically to the Department of Defense (DoD). It introduces additional requirements and clauses for defense contractors, particularly in areas such as cybersecurity, safeguarding sensitive information, and supporting national security.
Together, FAR and DFARS form the backbone of regulatory standards that contractors must meet to maintain government contract compliance.
Key differences between FAR and DFARS
While both FAR and DFARS frameworks regulate federal procurement processes, they serve different scopes and purposes:
Scope:
Far is broader and it applies to all federal agencies while DFARS is specific to defense contracts
Clauses
DFARS includes clauses that address national defense priorities, such as safeguarding Controlled Unclassified Information (CUI) and requirements for domestic manufacturing.
Unique requirements
DFARS mandates higher cybersecurity standards for defense contractors, such as compliance with DFARS 252.204-7012, which focuses on protecting sensitive defense-related information.
These differences are crucial for any contractor working in the defense sector. Failing to comply with DFAR requirements can lead to serious consequences, including contract loss or penalties.

Compliance requirements for FAR and DFARS
To maintain government contract compliance, understanding the obligations under FAR and DFAR is critical. While FAR applies to all federal government contractors, DFARS compliance is mandatory for any contractor working with the Department of Defense.
Here’s a quick breakdown of what contractors need to know:
FAR compliance
FAR spans over 2,300 pages and outlines the rules for virtually every aspect of federal contracting. To remain compliant, contractors must:
- Maintain accurate and auditable records
- Follow proper procurement and cost allocation procedures
- Submit timesheets promptly (often within 24 hours)
- Segregate allowable vs. unallowable costs
- Adhere to mandatory clauses that promote transparency and fairness

DFARS compliance
DFARS adds an extra layer of complexity, especially in areas like cybersecurity. Defense contractors must:
- Protect Covered Defense Information (CDI)
- Comply with cybersecurity requirements outlined in DFARS 252.204-7012
- Meet DoD standards for safeguarding controlled unclassified data
Compliance with DFAR requirements is not optional. Violations can lead to audits, penalties, or even exclusion from future DoD contracts.
Maintaining full FAR and DFAR compliance is vital to staying competitive in the federal and defense contracting space. Make sure you have the right tools to navigate the complexities of government contract compliance.
How FAR and DFARS impact small businesses
Understanding how FAR and DFAR affect small businesses is essential for achieving and maintaining government contract compliance. While these regulations can present significant challenges, they also offer valuable opportunities for growth within the federal and defense contracting space.
Opportunities for small businesses
Both FAR and DFARS contain provisions specifically designed to promote small business participation. This includes:
- Set-aside contracts reserved exclusively for small businesses
- Subcontracting incentives for prime contractors who partner with small businesses
- Access to mentorship programs and targeted procurement initiatives
Compliance challenges
Despite these advantages, many small businesses struggle with:
- Interpreting complex FAR and DFAR clauses
- Managing audits and maintaining thorough documentation
- Meeting cybersecurity requirements under DFARS, especially for protecting Covered Defense Information (CDI)
Fortunately, organizations like the Small Business Administration (SBA) offer guidance, training, and support to help small businesses meet government contract compliance requirements.
