EA vs CPA for Tax Work: The Numbers That Actually Matter
Last reviewed: July 9, 2026. This article reflects current IRS rules and EA exam requirements as of this date.
People ask whether the EA or CPA is better for tax work. The answer depends on what you actually want to do. But the numbers make the EA case clearer than most people realize.
The Time Commitment
The EA requires three exams. Each part takes roughly 40-60 hours to study if you're starting from zero.
| EA Part | Content | Study Hours |
|---|---|---|
| Part 1: Individuals | Filing status, deductions, credits, retirement, property | 40-60 |
| Part 2: Businesses | Sole props, partnerships, corps, trusts, depreciation | 40-60 |
| Part 3: Representation | IRS practice, ethics, appeals, collections, penalties | 30-50 |
| Total | 110-170 hours |
A bachelor's degree: roughly 5,400 hours. The EA is about 3% of the time commitment. For someone inheriting or starting a tax practice, the EA opens more doors than a BA.
The CPA requires 150 credit hours (roughly a master's degree), plus four exam sections, plus work experience under a licensed CPA. Total time: 1-3 years of study plus degree completion.
The Cost
| Credential | Exam Fees | Prep Materials | Education Requirement | Total |
|---|---|---|---|---|
| EA | ~$200 per part | $0-639 | None | ~$200-1,000 |
| CPA | ~$1,000 total | $1,500-3,000 | 150 credit hours | $2,500-30,000+ |
The EA can be done for $200 if you use free study materials. The CPA cannot be done cheap because the education requirement is the cost driver. The 150 credit hours alone cost thousands even at a community college.
What's Actually On the Exam
This is the most important difference that nobody talks about.
The EA exam is 100% tax. All three parts. Individuals, businesses, and representation. You don't study auditing. You don't study financial reporting. You don't study business concepts. Every hour you study is an hour spent on tax.
The CPA exam is roughly 25% tax and 75% audit, financial accounting, business environment, and regulation. Most of what you study has nothing to do with preparing tax returns or representing clients before the IRS.
For someone who wants to run a tax practice, the EA tests exactly what you need to know. The CPA tests a lot of things you don't.
IRS Representation Rights
This is where most comparisons get it wrong. Both credentials give you unlimited representation rights before the IRS. An EA can represent any client for any tax matter before any IRS office. Same as a CPA. Same as a tax attorney.
The difference: the EA tests deeper on IRS representation. Part 3 covers Circular 230, audits, appeals, collections, penalties, and professional ethics. This is the content that matters when you're sitting across from an IRS revenue officer.
The Decision Framework
Get the EA if:
- You want to do tax work specifically
- You don't have 150 credit hours and don't want to get them
- You want the fastest path to IRS representation rights
- You're changing careers and don't have an accounting background
- You want to run a tax practice
Get the CPA if:
- You want to do audit work
- You already have 150 credit hours
- You want the broader credential for non-tax roles (CFO, controller)
- You're already in public accounting and your firm requires it
For a solo tax office, the EA is the sharper tool. Less time. Less money. More tax content. Same IRS access. The only reason to get the CPA for tax work is if you're already most of the way there.
