Tax accountants work with individuals and corporations They calculate tax liability, prepare tax returns, and provide tax advice. To become an accountant, you’ll need a bachelor’s degree in accounting or a business degree with a focus in accounting. This is the bare minimum requirement. Most tax accountants are Certified Public Accountants (CPAs). This is because most companies prefer to hire CPAs. Many state accountancy boards require certain courses that aren’t offered in undergraduate degree programs, so a graduate degree in accounting may better prepare you for the CPA exam in some states.
