Certified Public Accountant

A Certified Public Accountant (CPA) is an accountant who has been licensed by a state board of accountancy in the United States (or by the equivalent body in countries that use the designation, including Australia and several in Asia) after meeting requirements for education, passing the Uniform CPA Examination, completing a period of supervised experience and, in most states, an ethics examination, and who maintains the licence through continuing professional education. The designation is the American profession's mark of qualification and is the legal requirement for signing audit opinions on financial statements and for certain tax representation.

CPAs work in public practice (audit, tax, advisory), in industry (controllers, finance directors, internal audit), in government and in education. The equivalent designations elsewhere include Chartered Accountant (UK, Ireland, Canada, Australia, India, South Africa and others), Chartered Certified Accountant (ACCA, international) and Chartered Professional Accountant (Canada, which merged its designations).

What it means

Accounting is a regulated profession because the public relies on the financial information accountants prepare and audit. The CPA licence is the mechanism by which the United States regulates it: only a licensed CPA may issue an audit or review report on financial statements that will be relied on by third parties, and the licence carries obligations of independence, competence and conduct enforced by state boards and by the profession's own bodies.

The path to the licence has four parts, with detail varying by state. Education: a bachelor's degree with a specified number of accounting and business credits, and in most states 150 semester hours in total, which usually means a master's degree or additional coursework beyond the standard four-year degree.

Examination: the Uniform CPA Examination, a four-section test (auditing, financial accounting and reporting, taxation and regulation, and a chosen discipline such as business analysis, information systems or tax compliance) with a pass rate per section of roughly 45% to 60%; candidates must pass all sections within a rolling window. Experience: typically one to two years of relevant work under the supervision of a licensed CPA.

Ethics: an examination on the profession's code in most states. The licence is then maintained by continuing professional education, commonly 40 hours a year, and by compliance with the state board's rules.

CPAs in public practice provide the services the licence exists for: audits, which give independent assurance on financial statements for shareholders, lenders and regulators; reviews and compilations, which give lower levels of assurance for smaller entities; tax preparation, planning and representation before the tax authorities; and advisory work in transactions, valuations, forensic accounting, systems and controls. The large international firms, national and regional firms and sole practitioners all employ CPAs, and the profession's structure runs from associate to partner.

CPAs in industry hold most senior finance roles. The designation signals a body of knowledge in financial reporting, control, tax and audit that boards and lenders value, and many companies require it for controller and chief financial officer positions.

CPAs in government work in audit offices, regulators and tax authorities; in education they teach and research. The designation's meaning for the public is the assurance it carries.

A set of accounts audited by a CPA firm has been examined by someone whose licence, livelihood and personal liability depend on the opinion being honest and competent, under standards set by the profession and enforced by regulators. The occasional failures of that assurance are notorious precisely because the standard is high.

For a business owner, engaging a CPA means access to someone bound by professional standards, insured, and answerable to a licensing body if the work falls short.

In practice

Real-world examples.

1

Example

A CPA in public practice signs the audit opinion on a listed company's annual report, having led a team of twelve through a four-month audit.

2

Example

A CPA serving as controller of a hospital group manages the monthly close, the internal controls and the relationship with the external auditors.

3

Example

A CPA sole practitioner prepares tax returns for 300 small business clients and represents two of them in tax authority examinations.

Think of it

A CPA is a licensed accountant who passed rigorous exams-qualified to audit and sign off on financials.

Case study

Seen in the real world.

A software company with 40 staff had grown to $9,000,000 of revenue with an in-house accountant who was competent but unqualified, and had never had an audit. When it sought venture capital, the investors' due diligence found that revenue had been recognised on signature of contracts rather than over the subscription period, overstating the previous year's revenue by $1,400,000; that deferred revenue had never been recorded; that sales tax had not been collected in three states where the company had customers; and that the stock option scheme had not been valued or expensed. None of this was fraud; it was the absence of anyone who knew the rules.

The investors reduced their valuation by 25% and made the appointment of a CPA as finance director and the engagement of a CPA firm for an audit conditions of the investment. The new finance director restated two years of accounts, registered for sales tax and negotiated the arrears, and put the company's reporting onto a basis the next round of investors accepted without adjustment. The chief executive's later comment was that the company had saved about $150,000 a year on finance staff and had paid for it with $4,000,000 of valuation.

Watch out

Common mistakes.

  • Assuming any accountant can sign an audit or represent a taxpayer in an examination. Those functions are reserved to licensed professionals.
  • Engaging a CPA only when a lender or buyer demands it, rather than early enough for the work to be done well and the problems found before others find them.
  • Treating the CPA's fee as a compliance cost only, when tax planning, control improvement and assurance value usually exceed it.

Questions

People also ask.

What is the difference between a CPA and an accountant?

Anyone can call themselves an accountant. A CPA has passed the licensing examination, met education and experience requirements, and holds a licence from a state board with the obligations that carries. Only CPAs can perform audits.

Is a CPA the same as a Chartered Accountant?

They are equivalent designations in different countries: CPA in the United States (and some others), Chartered Accountant in the UK, Canada (now CPA there too), Australia, India and elsewhere. Mutual recognition agreements allow qualified holders to practise across some borders.

Does a small business need a CPA?

For an audit or review, yes, by law. For tax and accounts, not necessarily, but a CPA brings knowledge, standards and accountability that a bookkeeper or unlicensed preparer may not, and the difference tends to show when the business grows, borrows or sells.
