Matt is an auto mechanic who runs his own small shop. When tax season comes, he hires an accountant from one of "the Big Four" accounting firms to help him file his business's tax return. In this scenario, Matt has most likely hired a accountant.

The correct answer is certified public.

Explanation:

Certified Public Accountants have studied this profession, possess their diplomas and must pass a public accountant exam. To use the CPA designation, these accounting professionals are required to educate themselves at a university about government law and pass a rigorous exam.

A CPA accountant can work within a company or create his own company to offer his professional services. Depending on the requirements of each state, the certification must be renewed every two (2) years. So CPAs have a higher level of responsibility than accountants or accountants.

A Certified Public Accountant (CPA) in addition to keeping the balance books of companies, performs tax and financial audit services for individuals, companies and non-profit organizations.

For this reason, accountants perform functions that are not at the professional level of accountants or Certified Public Accountants (CPAs). As companies grow, so do financial responsibilities when filing taxes. And CPAs are certified to handle or control any type of tax or accounting situation.

A Certified Public Accountant (CPA) must be current and qualified by the American Institute of Certified Public Accountants. The exam that a CPA accountant must pass is four parts and must be completed in a period of two years.
