When to Choose the CPA
The CPA is essential for public accounting and any role involving attestation, audit opinions, or tax return signing. It offers broader career flexibility and is required by law for certain functions.
- Planning a career in public accounting (audit or tax)
- Want maximum career flexibility across industries
- Interested in forensic accounting, SEC reporting, or litigation support
- May start your own accounting practice
When to Choose the CIA
The CIA is ideal for internal audit, risk management, and governance careers. The CIA is the only globally recognized internal audit certification, and The IIA positions it as the profession's benchmark credential.
- Career focused on internal audit or compliance
- Interested in enterprise risk management
- Want a globally recognized credential (IIA operates worldwide)
- Working in government, nonprofit, or IT audit
- Already in an internal audit role and want to formalize your expertise
Why Get Both
Many professionals choose to earn both the CPA and CIA. CPAs can take the CIA Challenge Exam (a condensed single exam: $995 for IIA members, $1,625 for non-members) instead of the standard 3-part format.
- Maximum career flexibility across external and internal audit
- CIA Challenge Exam provides an accelerated path for CPAs
- Demonstrates expertise in both financial reporting and governance
- Positions you for C-suite roles (CFO, CAE) that bridge both functions
Salary Comparison
Starting salaries are comparable between CPAs and CIAs. The IIA has not published a compensation study since 2013, so current certification-specific salary premiums for the CIA cannot be sourced; treat circulating premium figures as dated. BLS puts the May 2025 median for accountants and auditors at $83,680. At senior levels, CPAs generally have higher earning potential due to broader career paths including partner tracks.
- BLS median for all accountants and auditors: $83,680 (May 2025)
- CPAs keep the higher long-run ceiling via partner and CFO tracks
- The IIA last published CIA compensation data in 2013, so current CIA-specific salary bands cannot be sourced
- Employers value both certifications; premiums vary by role and market
