Sarbanes–Oxley Actvt
Certified Public Accountant (CPA) is the title of qualified accountants in numerous countries in the English-speaking world. In the United States, the CPA is a license to provide accounting services to the public. It is awarded by each of the 50 states for practice in that state. Additionally, almost every state (49 out of 50) has passed mobility laws to allow CPAs from other states to practice in their state. State licensing requirements vary, but the minimum standard requirements include passing the Uniform Certified Public Accountant Examination, 150 semester units of college education, and one year of accounting related experience.
Continuing professional education (CPE) is also required to maintain licensure. Individuals who have been awarded the CPA but have lapsed in the fulfillment of the required CPE or who have requested conversion to inactive status are in many states permitted to use the designation "CPA Inactive" or an equivalent phrase. In most U.S. states, only CPAs are legally able to provide attestation (including auditing) opinions on financial statements. Many CPAs are members of the American Institute of Certified Public Accountants and their state CPA society.
State laws vary widely regarding whether a non-CPA is even allowed to use the title "accountant." For example, Texas prohibits the use of the designations "accountant" and "auditor" by a person not certified as a Texas CPA, unless that person is a CPA in another state, is a non-resident of Texas, and otherwise meets the requirements for practice in Texas by out-of-state CPA firms and practitioners.[1]
Many other countries also use the title CPA to designate local public accountants.
Services provided
One important function performed by CPAs relates to assurance services. The most commonly performed assurance services are financial audit services where CPAs attest to the reasonableness of disclosures, the freedom from material misstatement, and the adherence to the applicable generally accepted accounting principles (GAAP) in financial statements. CPAs can also be employed within corporations (termed "the private sector" or "industry") in finance or operations positions such as financial analyst, finance manager, controller, chief financial officer (CFO), or chief executive officer (CEO). These CPAs do not provide services directly to the public.
Although some CPA firms serve as business consultants, the consulting role has been under scrutiny following the Enron scandal where Arthur Andersen simultaneously provided audit and consulting services which affected its ability to maintain independence in its audit duties. This incident resulted in many accounting firms divesting their consulting divisions, but this trend has since reversed. In audit engagements, CPAs are (and have always been) required by professional standards and Federal and State laws to maintain independence (both in fact and in appearance) from the entity for which they are conducting an attestation (audit and review) engagement. Although most individual CPAs who work as consultants do not also work as auditors, if the CPA firm is auditing the same company that the firm also does consulting work for, then there is a conflict of interest. This conflict voids the CPA firm's independence for multiple reasons, including: (1) the CPA firm would be auditing its own work or the work the firm suggested, and (2) the CPA firm may be pressured into unduly giving a positive (unmodified) audit opinion so as not to jeopardize the consulting revenue the firm receives from the client.
CPAs also have a niche within the income tax return preparation industry. Many small to mid-sized firms have both a tax and an auditing department. Along with attorneys and Enrolled Agents, CPAs may represent taxpayers in matters before the Internal Revenue Service (IRS). Although the IRS regulates the practice of tax representation, it has no authority to regulate tax return preparers.[2]
Many states also allow unlicensed accountants to work as public accountants. For example, California allows unlicensed accountants to work as public accountants if they work under the control and supervision of a CPA.[3] However, the California Board of Accountancy itself has determined that the terms "accountant" and "accounting" are misleading to members of the public, many of whom believe that a person who uses these terms must be licensed. As part of the California Poll, survey research showed that 55 percent of Californians believe that a person who advertises as an "accountant" must be licensed, 26 percent did not believe a license was required, and 19 percent did not know.[4]
Whether providing services directly to the public or employed by corporations or associations, CPAs can operate in virtually any area of finance including:
Assurance and attestation services
Corporate finance (merger and acquisition, initial public offerings, share and debt issuings)
Corporate governance
Estate planning
Financial accounting
Governmental accounting
Financial analysis
Financial planning
Forensic accounting (preventing, detecting, and investigating financial frauds)
Income tax
Information technology, especially as applied to accounting and auditing
Management consulting and performance management
Tax preparation and planning
Venture capital
Financial reporting
Regulatory compliance
CPA exam

To become a CPA in the United States, the candidate must sit for and pass the Uniform Certified Public Accountant Examination (Uniform CPA Exam), which is set by the American Institute of Certified Public Accountants (AICPA) and administered by the National Association of State Boards of Accountancy (NASBA). The CPA designation was first established in law in New York State on April 17, 1896.[5]
Eligibility to sit for the Uniform CPA Exam is determined by individual state boards of accountancy. Many states have adopted what is known as the "150 hour rule" (150 college semester units or the equivalent), which usually requires an additional year of education past a regular 4 year college degree, or a master's degree.  Some universities offer a 5-year combined bachelor's/master's degree program, allowing a student to earn both degrees while receiving the 150 hours needed for exam eligibility.
The Uniform CPA Exam tests general principles of state law such as the laws of contracts and agency (questions not tailored to the variances of any particular state) and some federal laws as well.[6]
Other licensing and certification requirements
Although the CPA exam is uniform, licensing and certification requirements are imposed separately by each state's laws and therefore vary from state to state.
State requirements for the CPA qualification can be summed up as the Three Es—Education, Examination and Experience. The education requirement normally must be fulfilled as part of the eligibility criteria to sit for the Uniform CPA Exam. The examination component is the Uniform CPA Exam itself. Some states have a two-tier system whereby an individual would first become certified—usually by passing the Uniform CPA Exam. That individual would then later be eligible to be licensed once a certain amount of work experience is accomplished. Other states have a one-tier system whereby an individual would be certified and licensed at the same time when both the CPA exam is passed and the work experience requirement has been met.
Two-tier states include Alabama, Florida, Illinois, Montana, and Nebraska. The trend is for two-tier states to gradually move towards a one-tier system. Since 2002, the state boards of accountancy in Washington and South Dakota have ceased issuing CPA "certificates" and instead issue CPA "licenses." Illinois planned to follow suit in 2012.[7]
A number of states are two-tiered, but require work experience for the CPA certificate, such as Ohio and .
Work experience requirement
The experience component varies from state to state:
The two-tier states generally do not require that the individual have work experience to receive a CPA certificate. (Work experience is required, however, to receive a license to practice.)
Some states, such as Massachusetts, waive the work experience requirement for those with a higher academic qualification compared to the state's requirement to appear for the Uniform CPA.
The majority of states still require work experience to be of a public accounting nature, namely two years audit or tax experience, or a combination of both. An increasing number of states, however, including Oregon, Virginia, Georgia and Kentucky, accept experience of a more general nature in the accounting area. In Texas, only one year of experience in accounting under the supervision of a CPA is required; such experience does not have to be in public accounting. This allows persons to obtain the CPA designation while working for a corporation's finance function.
The majority of states require an applicant's work experience to be verified by someone who is already licensed as a CPA. This requirement can cause difficulties for applicants based outside the United States. However, some states such as Colorado and Oregon also accept work experience certified by a Chartered Accountant.
Ethics
Over 40 of the state boards now require applicants for CPA status to complete a special examination on ethics, which is effectively a fifth exam in terms of requirements to become a CPA.  The majority of these accept the AICPA self-study Professional Ethics for CPAs CPE course or another course in general professional ethics. Many states, however, require that the ethics course include a review of that state's specific rules for professional practice.
Continuing professional education
Like other professionals, CPAs are required to take continuing education courses toward continuing professional development (continuing professional education [CPE]) to renew their license. Requirements vary by state (Wisconsin does not require any CPE for CPAs[8][9]) but the vast majority require an average of 40 hours of CPE every year with a minimum of 20 hours per calendar year. The requirement can be fulfilled through attending live seminars, webcast seminars, or through self-study (textbooks, videos, online courses, all of which require a test to receive credit).[10] In general, state boards accept group live and group internet-based credits for all credit requirements, while some states cap the number of credits obtained through the self-study format. All CPAs are encouraged to periodically review their state requirements.[11] As part of the CPE requirement, most states require their CPAs to take an ethics course at some frequency (such as every or every other renewal period). Ethics requirements vary by state and the courses range from 2–8 hours. AICPA guidelines (which are adopted by many state boards) grant licensees 1 hour of CPE credit for every 50 minutes of instruction.[12][13]
Loss of licensure
A CPA license may be suspended or revoked for various reasons.  Common reasons include these:
Allowing the license to lapse without renewing in a timely manner.
Performing attestation services under an unlicensed/unregistered CPA firm or under a CPA firm permit which has expired.
Continuing to hold out as an active CPA on an expired license, which includes continued use of the CPA title on business cards, letterhead, office signage, correspondence, etc. after the license has expired.
Using fraud or deceit in obtaining or renewing the CPA license, the most common occurrence being misrepresenting or falsifying compliance with or completion of the continuing education requirements as a condition for renewal.
"Discreditable acts", which can include 1) failure to follow applicable standards (such as auditing standards when examining financial statements, or tax code when preparing tax returns) or 2) violation of felony or serious misdemeanor criminal laws (which may or not be related to the practice of accountancy; a notable example of a CPA whose license was revoked for non-financial related criminal activity is John Battaglia, convicted of the capital murders of his children)[14]
Other accounting designations sometimes confused with CPA
Many states had (although a few still do) a second tier of accountant qualification in addition to that of CPA, usually entitled "Public Accountant" or "Licensed Public Accountant" (with designatory letters "PA" or "LPA"), although other titles have included "Registered Public Accountant" (RPA), "Accounting Practitioner" (AP), and "Registered Accounting Practitioner" (RAP). Such designations served to help regulate the practice of public accounting in that state by grandfathering through licensure non-CPA accountants who were already practicing public accounting before a regulatory state accountancy law was enacted. The majority of states have closed the designation "Public Accountant" (PA) to new entrants, with only five states continuing to offer the designation. Many PAs belong to the National Society of Accountants.
Many states prohibit the use of the designations "Public Accountant" or "Licensed Public Accountant" (or the abbreviations "PA" or "LPA") by a person who is not certified as a PA in that state.
In Australia the designation "Public Accountant" is used by members of the Institute of Public Accountants of Australia.
Practice mobility
An accountant is required to meet the legal requirements of any state in which the accountant wishes to practice.
In recent years, practice mobility for CPAs has become a major business concern for CPAs and their clients. Practice mobility for CPAs is the general ability of a licensee in good standing from a substantially equivalent state to gain practice privilege outside of their home state without getting an additional license in the state where the CPA will serve a client or an employer. In today's digital age, many organizations requiring the professional services of CPAs conduct business on an interstate and international basis and have compliance responsibilities in multiple jurisdictions. As a result, the practice of CPAs often extends across state lines and international boundaries.[15]
Differing requirements for CPA certification, reciprocity, temporary practice and other aspects of state accountancy legislation in the 55 U.S. licensing jurisdictions (the 50 states, Puerto Rico, the District of Columbia, the U.S. Virgin Islands, Guam and the Commonwealth of the Northern Mariana Islands) make the interstate practice and mobility of CPAs more complicated. By removing boundaries to practice in the U.S., CPAs are able to more readily serve individuals and businesses in need of their expertise. At the same time, the state board of accountancy's ability to discipline is enhanced by being based on a CPA and the CPA firm's performance of services (either physically, electronically or otherwise within a state), rather than being based on whether a state license is held.[15]
The American Institute of Certified Public Accountants (AICPA) and the National Association of State Boards of Accountancy (NASBA) have analyzed the current system for gaining practice privileges across state lines and have endorsed a uniform mobility system. This model approach is detailed through the substantial equivalency provision (Section 23) of the Uniform Accountancy Act (UAA). The UAA is an "evergreen" model licensing law co-developed, maintained, reviewed and updated by the AICPA and NASBA.  The model provides a uniform approach to regulation of the accounting profession.[15]
Under Section 23 of the UAA, a CPA with a license in good standing from a jurisdiction with CPA licensing requirements essentially equivalent to those outlined in the UAA is deemed to be “substantially equivalent,” or a licensee who individually meets the requirements of:
Obtaining 150 credit hours (150 college semester units or the equivalent) with a baccalaureate degree
Minimum one year of CPA experience
Passing the Uniform CPA Examination
Uniform adoption of the UAA's substantial equivalency provision creates a system similar to the nation's driver's license program by providing CPAs with mobility while retaining and strengthening state boards’ ability to protect the public interest. The system enables consumers to receive timely services from the CPA best suited to the job, regardless of location, and without the hindrances of unnecessary filings, forms and increased costs that do not protect the public interest.[15]
As of October 2012, a total of 49 out of the 50 states and the District of Columbia have passed mobility laws and are now in the implementation and navigation phases.[16]  Only the Commonwealth of the Northern Mariana Islands, the Virgin Islands, Hawaii, Puerto Rico and Guam have not passed mobility laws. On September 20, California Governor Jerry Brown signed legislation that permits cross-border mobility for CPAs.  The law went into effect July 1, 2013.[17]  The District of Columbia passed mobility laws that went into effect on October 1, 2012.[18]
AICPA membership
The CPA designation is granted by individual state boards, not the American Institute of Certified Public Accountants (AICPA). Membership in the AICPA is not obligatory for CPAs, although some CPAs do join. To become a full member of AICPA, the applicant must hold a valid CPA certificate or license from at least one of the fifty-five U.S. state/territory boards of accountancy; some additional requirements apply.
AICPA members approved a proposed bylaw amendment to make eligible for voting membership individuals who previously held a CPA[19] certificate/license or have met all the requirements for CPA certification in accordance with the Uniform Accountancy Act (UAA).  The AICPA announced its plan to accept applications from individuals meeting these criteria, beginning no later than January 1, 2011.
State CPA association membership
CPAs may also choose to become members of their local state association or society (also optional). Benefits of membership in a state CPA association range from deep discounts on seminars that qualify for continuing education credits to protecting the public and profession's interests by tracking and lobbying legislative issues that affect local state tax and financial planning issues.
CPAs who maintain state CPA society memberships are required to follow a society professional code of conduct (in addition to any code enforced by the state regulatory authority), further reassuring clients that the CPA is an ethical business professional conducting a legitimate business who can be trusted to handle confidential personal and business financial matters. State CPA associations also serve the community by providing information and resources about the CPA profession and welcome inquiries from students, business professionals and the public-at-large.
CPAs are not normally restricted to membership in the state CPA society in which they reside or hold a license or certificate. Many CPAs who live near state borders or who hold CPA status in more than one state may join more than one state CPA society.
