What is the difference between CA and CPA?
CA stands for chartered accountant, the qualification awarded by professional bodies in the UK, Ireland, India, Australia and elsewhere. CPA stands for certified public accountant, the equivalent American qualification. Both are fully qualified accountants, but they are licensed by different bodies.
