What Is the AICPA? Definition, Role, and Standards

What Is AICPA?

The AICPA, which stands for the American Institute of Certified Public Accountants, is the national professional organization for CPAs in the United States. It’s a nonprofit, and its primary role is setting the ethical, auditing, and professional standards that CPAs are expected to follow.

The organization was founded in 1887, originally as the American Association of Public Accountants. It’s gone through several name changes since then, but the core mission has stayed consistent: define what it means to be a CPA and protect the integrity of the profession.

Today, the AICPA represents roughly 597,000 members across the US and globally. In 2017, the AICPA formed a strategic alliance with CIMA (the Chartered Institute of Management Accountants), creating the Association of International Certified Professional Accountants. That alliance expanded its global reach significantly, particularly in management accounting.

So what is the AICPA in accounting? It’s the professional body that sets the rules, develops the credentials, and advocates for the profession at the national level. Even if you don’t interact with it directly, the standards it produces affect how accounting and audit work gets done across the country.

What Does the AICPA Do?

The AICPA wears a lot of hats. Here are the most important ones.

• Sets ethical standards for CPAs. The AICPA Code of Professional Conduct is the ethical framework every CPA is expected to follow. It covers independence, integrity, objectivity, and due care. In practice, this set of principles that governs how CPAs make decisions, handle conflicts of interest, and maintain public trust. Violations can lead to disciplinary action and loss of membership.
• Develops and administers the Uniform CPA Exam. The AICPA is responsible for creating and maintaining the CPA Exam, which is the primary licensing requirement for CPAs across all US states and territories. The exam has evolved over the years to reflect changes in the profession, including a growing focus on data analytics and technology.
• Sets auditing standards for non-public entities. Through the Auditing Standards Board (ASB), the AICPA issues auditing standards that apply to audits of private companies, nonprofits, and government organizations. These include the Statements on Auditing Standards (SAS), as well as the Statements on Standards for Accounting and Review Services (SSARS) and Statements on Standards for Attestation Engagements (SSAE).
• Publishes guidance and practice resources. Beyond formal standards, the AICPA produces technical practice aids, industry-specific guides, and interpretive guidance that help practitioners navigate complex areas of accounting.

One important distinction worth noting: the AICPA doesn’t set GAAP. That responsibility shifted to the Financial Accounting Standards Board (FASB) in the 1970s. Before that, the AICPA’s Accounting Principles Board was the primary standard-setter. Today, FASB handles financial reporting standards for public companies, while the AICPA continues to shape auditing standards, ethics, and professional practice more broadly.

AICPA Membership: Who It’s For and What It Offers

AICPA membership is open to CPAs, CPA exam candidates, and accounting professionals who hold associate membership. You don’t have to be a licensed CPA to join, though full membership benefits are tied to the CPA credential.

Here’s what members get access to:

• Continuing professional education (CPE). The AICPA offers a wide library of CPE courses, conferences, and webcasts to help members stay current with evolving standards and regulations.
• Specialized credentials. Beyond the CPA license itself, the AICPA offers several additional designations. These include the CGMA (Chartered Global Management Accountant), CFF (Certified in Financial Forensics), CITP (Certified Information Technology Professional), ABV (Accredited in Business Valuation), and PFS (Personal Financial Specialist). Each credential targets a specific area of expertise within accounting.
• Advocacy. The AICPA represents the profession before Congress, regulatory agencies, and state boards. It actively lobbies on issues like tax policy, audit reform, and licensing requirements.
• Peer community and resources. Members gain access to technical hotlines, peer discussion groups, and industry-specific sections that connect them with other professionals facing similar challenges.

It’s also worth highlighting the CPA Evolution initiative. This is an ongoing effort by the AICPA and NASBA (National Association of State Boards of Accountancy) to transform the CPA licensure model. The goal is to better reflect the skills modern CPAs actually need, including deeper competency in data analytics, technology, and strategic thinking. The updated CPA Exam launched in 2024, and it represents one of the most significant changes to the credential in decades.

Why the AICPA Matters for Accounting Teams (Not Just CPAs)

You don’t need to be a CPA to feel the AICPA’s influence. If your team prepares financial statements, manages compliance, or works with external auditors, you’re operating within a framework the AICPA helped build.

Here are a few practical examples.

• Auditors follow AICPA standards. If your company is audited by a firm that isn’t one of the PCAOB-regulated firms handling public company audits, those auditors are likely following standards issued by the AICPA’s Auditing Standards Board. Understanding what those standards require can help your team prepare more effectively for audit season.
• AICPA guidance shapes how accounting software works. The standards and best practices the AICPA publishes influence how vendors design their products. Everything from how lease accounting calculations are handled under ASC 842 to how revenue recognition workflows are built under ASC 606 ties back to the frameworks the AICPA helps maintain.
• AICPA resources help teams navigate complex standards. Even if your team members aren’t AICPA members, the organization’s technical guidance, practice aids, and interpretive resources are widely referenced across the profession. When a new standard rolls out or an existing one gets updated, AICPA publications are often the first place practitioners turn for clarity.
• The AICPA’s stance on AI matters. The AICPA is actively publishing guidance on how AI, machine learning, and data analytics should be used in accounting and audit. As these technologies become more common, the AICPA’s position will shape what’s considered acceptable practice and what falls outside professional norms.

The AICPA and the Future of Accounting

The accounting profession is in the middle of a real shift. Manual processes are giving way to automation. Data analytics is becoming a core competency. And AI is moving from an abstract concept to something teams are actually using in their workflows.

The AICPA is playing a role in shaping how this transition happens. The CPA Evolution initiative reflects the profession’s recognition that the skills CPAs need are changing. The updated exam places more emphasis on analytical thinking, technology, and the ability to work alongside digital tools. That’s a meaningful signal about where the profession is headed.

At the same time, the AICPA is publishing guidance to help firms and teams adopt emerging technology responsibly. This includes resources on AI governance, data quality, and the ethical implications of automation in professional practice.

For accounting teams, the takeaway is straightforward: the standards and expectations you work under are evolving, and the tools you use need to keep pace. 

This is exactly the environment Trullion is built for. By helping teams manage complex standards like ASC 842 and ASC 606 with less manual work and more transparency, Trullion gives accounting and audit teams the confidence to operate within these shifting requirements without adding overhead.
