The letters "CPA" appear on business cards, office doors, and professional websites throughout the country, but many people have only a vague understanding of what Certified Public Accountants actually do. While most recognize that CPAs work with numbers and taxes, the full scope of their capabilities, authority, and value often remains unclear.
Understanding what CPAs do matters because it helps you know when to hire one, what to expect from their services, and how they differ from other financial professionals. CPAs offer far more than tax preparation—they provide strategic guidance, ensure regulatory compliance, protect financial integrity, and serve as trusted advisors on complex business and personal financial matters. This comprehensive look at the CPA profession reveals why this credential commands respect and how CPAs create value for their clients.
The CPA Credential: More Than Just Letters
CPA stands for Certified Public Accountant, a professional license granted by state boards of accountancy. Unlike simple certifications that require passing an exam, the CPA license demands rigorous education, examination, experience, and ongoing professional development. Each state sets its own requirements, but common elements create consistency nationwide.
Prospective CPAs must complete at least 150 semester hours of college education, typically requiring a master's degree or equivalent beyond a bachelor's degree. This education must include substantial accounting and business coursework covering financial accounting, auditing, taxation, business law, and ethics.
After meeting education requirements, candidates face the Uniform CPA Examination, a comprehensive four-part test covering Auditing and Attestation, Business Environment and Concepts, Financial Accounting and Reporting, and Regulation (including taxation). The exam is notoriously difficult, with section pass rates typically around 50 percent. Candidates have 18 months to pass all four sections, and many require multiple attempts on one or more sections.
Passing the exam isn't the final step. Most states require one to two years of professional experience under the supervision of a licensed CPA. This ensures new CPAs develop practical skills and professional judgment before practicing independently. Only after completing all requirements does an individual receive CPA licensure from their state board.
The licensing process doesn't end there. CPAs must maintain their license through continuing professional education, typically 40 hours annually, covering accounting, auditing, tax, ethics, and other relevant topics. This requirement ensures CPAs stay current as standards, laws, and best practices evolve. State boards also enforce ethical standards and can discipline or revoke licenses for professional misconduct.
Core Services CPAs Provide
Tax Services
Tax preparation and planning represent the most visible CPA service, especially for individuals and small businesses. CPAs prepare federal, state, and local tax returns for individuals, businesses, estates, trusts, and non-profit organizations. Their deep knowledge of tax law helps identify deductions, credits, and strategies that minimize tax liability while ensuring compliance.
Beyond annual tax preparation, CPAs provide year-round tax planning. They advise on the tax implications of business decisions, real estate transactions, investment strategies, and major life events. This proactive approach identifies opportunities and prevents costly mistakes that arise when tax considerations are ignored until filing season.
CPAs with appropriate credentials have unlimited representation rights before the IRS. They can represent clients in audits, appeals, collection matters, and other proceedings. Their expertise in tax law and IRS procedures makes them effective advocates who can negotiate favorable outcomes and protect client interests during tax controversies.
Audit and Assurance Services
One of the CPA's most distinctive capabilities is providing audit and assurance services. Only CPAs can perform independent audits of financial statements, expressing an opinion on whether those statements fairly represent an organization's financial position and results of operations. Banks, investors, regulatory agencies, and other stakeholders often require audited financial statements, making this CPA service essential for many businesses.
CPAs conduct various levels of financial statement engagements. Audits provide the highest level of assurance through extensive testing and verification. Reviews offer limited assurance through inquiry and analytical procedures. Compilations present financial information in proper form without providing assurance but still add credibility through CPA involvement.
Attestation extends beyond financial statements. CPAs can provide assurance on internal controls, compliance with regulations, prospective financial information, and other matters where independent verification adds value. This capability makes CPAs valuable in due diligence, regulatory compliance, and risk management.
Business Advisory Services
Many CPAs serve as strategic business advisors, helping clients make informed decisions about operations, growth, and financial management. They analyze financial performance, identifying trends, opportunities, and areas of concern. Their objective perspective helps business owners see patterns and issues that might not be apparent from daily operations.
CPAs assist with business planning, including budgeting, forecasting, and cash flow management. They help businesses prepare for financing by developing financial projections and business plans that satisfy lender requirements. When businesses consider expansion, acquisition, or sale, CPAs provide valuation services, due diligence, and transaction structuring advice.
Internal control assessment is another important advisory service. CPAs evaluate whether businesses have adequate systems to prevent errors and fraud, ensure accurate financial reporting, and comply with regulations. They recommend improvements that protect assets and enhance operational efficiency.

Specialized CPA Practice Areas
While all CPAs share the same basic qualifications, many specialize in specific practice areas where they develop deep expertise. Understanding these specializations helps clients find CPAs whose experience aligns with their specific needs.
Public Accounting
Public accounting firms provide services to external clients, ranging from sole practitioners to massive international firms. CPAs in public accounting typically offer multiple services including tax, audit, and consulting. Large firms often specialize further, with CPAs focusing on specific industries like healthcare, real estate, technology, or manufacturing. This industry specialization allows CPAs to understand unique challenges and opportunities facing clients in those sectors.
Corporate and Private Accounting
Many CPAs work within corporations, serving as controllers, chief financial officers, or in other financial management roles. These CPAs handle internal financial reporting, budgeting, analysis, and strategic planning. They ensure accurate financial records, manage relationships with external auditors and tax professionals, and provide financial information that supports business decisions.
Forensic Accounting
Forensic CPAs investigate financial crimes, fraud, and disputes. They analyze financial records to detect irregularities, trace assets, calculate damages in litigation, and provide expert testimony in legal proceedings. Their work supports criminal investigations, civil litigation, and internal fraud examinations. This specialized area requires both accounting expertise and investigative skills.
Government and Non-Profit
CPAs working in government and non-profit sectors understand the unique accounting standards and regulations governing these entities. They ensure compliance with government accounting standards, manage grant accounting and reporting, and handle tax-exempt organization requirements. Their work supports transparency and accountability in public service organizations.
Personal Financial Planning
Some CPAs specialize in personal financial planning, earning additional credentials like the Personal Financial Specialist (PFS) designation. These CPAs provide comprehensive financial planning services, including retirement planning, estate planning, investment advice, and risk management. Their accounting background gives them unique perspective on tax-efficient wealth accumulation and preservation.
Why the CPA Credential Matters
The value of working with a CPA extends beyond their technical knowledge. The credential represents accountability and trustworthiness that comes from state licensing and regulatory oversight. State boards investigate complaints, enforce ethical standards, and can discipline CPAs who violate professional rules. This accountability protects clients in ways that working with unlicensed practitioners does not.
CPAs must maintain professional liability insurance, providing additional protection if errors occur. They follow professional standards established by organizations like the American Institute of CPAs and the Public Company Accounting Oversight Board. These standards govern everything from audit procedures to ethical conduct, ensuring quality and consistency across the profession.
The CPA's duty of confidentiality protects client information. Communications with CPAs enjoy certain legal protections, particularly in tax matters, giving clients confidence that sensitive financial information remains private. This trust forms the foundation of effective CPA-client relationships.
CPAs bring objectivity and independence to financial matters. They're trained to approach situations analytically without emotional bias, providing honest assessments even when the truth is uncomfortable. This objectivity helps clients make better decisions based on facts rather than wishful thinking or fear.

When You Need a CPA vs Other Professionals
Understanding what CPAs do helps clarify when their services are necessary versus when other professionals might suffice. You need a CPA when your business requires audited financial statements for lending, bonding, or regulatory purposes. Only CPAs can provide this essential service, making them indispensable for many businesses.
Complex tax situations benefit from CPA involvement. While basic individual returns might be handled by tax preparers, business returns, multi-state taxation, significant investment income, or complex deductions warrant CPA expertise. The tax savings and audit protection CPAs provide typically exceed their cost.
Business owners facing major decisions—buying or selling a business, changing entity structure, seeking financing, or planning succession—should consult CPAs. Their comprehensive business knowledge and objective analysis help avoid costly mistakes and identify optimal strategies.
However, not every financial task requires a CPA. Routine bookkeeping can be handled by bookkeepers or accounting software. Basic investment advice might come from financial advisors. Simple tax returns could be prepared by qualified tax preparers. The key is matching the complexity of your needs to the appropriate level of expertise.
The Value of CPA Services
CPAs typically charge higher fees than unlicensed accounting professionals, reflecting their education, expertise, and the value they provide. However, viewing these fees as costs rather than investments misses the picture. Good CPAs save clients more money than they charge through tax strategies, better business decisions, and avoiding costly errors.
The peace of mind that comes from knowing a highly qualified, licensed professional handles your financial matters has real value. CPAs catch issues before they become problems, identify opportunities you might miss, and provide confidence that financial information is accurate and compliant.
For businesses, CPAs enhance credibility with external stakeholders. Financial statements prepared or audited by CPAs carry more weight with banks, investors, and partners than internally-prepared documents. This credibility can improve financing terms, attract investors, and facilitate business relationships.
CPAs also provide continuity and institutional knowledge. As they work with clients over years, they develop deep understanding of the business, industry, and financial patterns. This relationship enables proactive advice and early identification of concerns, adding value beyond any single service they provide.
Finding the Right CPA
Not all CPAs are equally suited to every client's needs. When selecting a CPA, consider their specialization and experience with situations similar to yours. A CPA specializing in large corporate audits might not be the best fit for personal tax preparation, while a CPA focused on individual taxation might lack expertise in complex business structures.
Ask about their communication style and availability. You want a CPA who explains things clearly, responds promptly to questions, and makes you feel confident in their advice. References from clients with similar needs provide valuable insight into how the CPA works.
Verify credentials through your state board of accountancy. Confirm the CPA license is active and check for any disciplinary actions. Most states provide online verification tools making this quick and easy.
Consider the scope of services you need now and might need in the future. A CPA who can grow with you as your financial situation becomes more complex provides continuity and avoids the need to change professionals repeatedly.
