The stakes are real. An S Corp deals with Form 1120-S, Schedule K-1 reporting, shareholder-employee payroll, reasonable compensation, distributions and state filings. Miss a deadline and the IRS charges $255 per month, per shareholder, for tax-year 2025 returns with no tax due, according to the 2025 Form 1120-S instructions.
A note for Australian readers: an S Corp is a U.S. tax classification. If you own a U.S. entity, assess U.S. federal and state obligations separately from your Australian tax and residency position, and get advice on each.
Key Takeaways
- CPAs and EAs can both prepare S Corp returns and represent you before the IRS.
- An EA suits tax-focused needs: compliance, planning and IRS correspondence.
- A CPA suits broader accounting, financial reporting, attest work and complex planning.
- Choose based on S Corp and cross-border experience, scope, communication and pricing, not the title.
CPA vs. EA for an S Corp: Quick Comparison
| Area | CPA | EA |
|---|---|---|
| Form 1120-S and individual returns | Can prepare; verify direct S Corp experience | Can prepare; often focused on federal compliance and planning |
| IRS representation | Unlimited representation rights | Unlimited rights, including audits, collections and appeals |
| Audit, review, compilation | May perform when licensed and qualified under state rules | Does not perform CPA-level attest work |
| Bookkeeping, payroll, advisory | Offered or coordinated by some firms; not automatic | Offered or coordinated by some; scope varies widely |
Unlimited representation rights belong to both credentials, per the IRS credential guidance. Whether your engagement actually includes audit, collection or appeals support is a separate question. Get it in writing.
Cost and engagement structure
Credential is a poor predictor of price. Compare quotes line by line:
- Form 1120-S and shareholder K-1s
- Bookkeeping and catch-up work
- Shareholder-employee payroll and reasonable-compensation review
- State returns
- Tax planning meetings
- IRS notice representation
Complexity, record quality, number of states and cross-border work all move the quote. Ask for a written flat fee or package rather than relying on rules of thumb.
What CPAs and EAs Do for an S Corp
Certified Public Accountant (CPA)
State boards of accountancy licence CPAs. Requirements for education, experience and ethics vary by jurisdiction, so verify a licence through the relevant state board or NASBA's CPAverify.
An S Corp-focused CPA typically:
- Prepares Form 1120-S and reviews shareholder basis and K-1 data
- Coordinates payroll and reasonable compensation
- Advises on distributions
- Prepares or coordinates your individual return
As you grow, a CPA's wider toolkit matters: financial statements, lender or investor reporting, multi-state planning, restructuring, forecasting and, where eligible, attest services.
Not every CPA audits, handles IRS disputes or plans proactively. Ask what share of the firm's work is S Corps, and whether the person you meet will handle your account.
Enrolled Agent (EA)
An EA is a federally authorised tax practitioner. EAs qualify by passing the three-part Special Enrollment Examination or through qualifying IRS employment, and renew with 72 hours of continuing education per three-year cycle, per the IRS enrolled agent information.
An S Corp-focused EA typically:
- Prepares Form 1120-S and coordinates K-1 reporting
- Estimates tax payments and reviews deductions
- Supports payroll tax compliance
- Responds to federal notices
An EA fits a closely held S Corp with clean books, tax-driven needs and no requirement for audited or reviewed statements.
The limits: EAs don't perform CPA-level attest services. Confirm rather than assume they cover bookkeeping, payroll, state filings, international tax and business advisory.
CPA vs. EA: Which Is Better for Your S Corp?
Neither credential wins for every S Corp. The IRS and professional bodies describe what each can do, but they do not rank one above the other. Match the professional to the work you need:
- Federal and state filings
- Shareholder payroll and basis tracking
- Bookkeeping quality and financial statements
- IRS exposure
- Foreign ownership and growth plans
Choose an EA when
- Your needs are federal and state compliance, Form 1120-S, K-1s and planning
- You want strong IRS notice support
- No one requires attest services or extensive financial reporting
Choose a CPA when
- A lender or investor wants audited or reviewed statements
- You need multi-state accounting, transaction support or forecasting
- You want advisory work alongside tax
Use experience as the deciding filter
Ask for examples involving similar S Corps, shareholder-employee payroll, reasonable compensation, multi-state filings and Australian or other foreign ownership. Check the IRS Directory of Federal Tax Return Preparers, and ask who prepares the return and who is reachable year-round.
Consider a hybrid arrangement
An EA can handle tax preparation and IRS representation while a CPA or accounting team covers reporting, audit or complex cross-border work. Decide up front who owns the compliance calendar and client communication.
One caution for foreign owners: S Corp eligibility rules exclude nonresident-alien shareholders, per the IRS S corporation guidance. If you're an Australian resident, confirm your eligibility with a U.S. tax professional before relying on S Corp status.
Real-World Examples and Decision Scenarios
The scenarios below are illustrative examples, not documented client results. Use them to match your situation when choosing between a CPA and an EA.
Scenario 1: A straightforward S Corp, an EA fits. A single-owner consulting company has clean books and one state filing. The trigger is a CP162A late-filing notice. The owner hires an EA for Form 1120-S, K-1 preparation, estimated payments and notice response. The likely outcome is cleaner filing coordination and a faster reply to the IRS.
Scenario 2: A growing, cross-border S Corp, a CPA fits. A multi-state business needs reviewed financial statements for a bank loan and is adding staff. The trigger is the lender's requirement. A CPA firm prepares the statements, handles multi-state planning and coordinates payroll and tax. The likely outcome is clearer financial reporting and one team accountable for the calendar.
The takeaway: pick the professional whose verified scope matches the work.
Australian businesses with U.S. S Corp obligations can talk to VJM Global about cross-border accounting, tax compliance and advisory. Its team includes CPAs, Chartered Accountants and U.S.-compliant professionals, and its U.S. support covers federal and state filings, payroll and IRS-notice documentation. VJM Global doesn't replace a state-licensed CPA or EA where a specific U.S. licence is required.
Conclusion
An EA isn't a lesser choice, and a CPA isn't automatically the better one. The right fit depends on whether your S Corp needs tax-focused compliance or broader accounting, reporting and advisory support.
Before you hire, lock in the basics:
- List the services you need
- Request a written scope and fee structure
- Verify credentials, plus S Corp and cross-border experience
- Clarify who handles payroll, state filings, IRS notices and year-round questions
You remain responsible for your return, whoever prepares it.
Frequently Asked Questions
Should I hire a CPA or an EA for my S Corp?
Either can handle S Corp tax preparation and planning. Pick an EA for tax-focused needs, and a CPA for broader accounting, financial reporting, attest work or strategic advisory.

Not necessarily. A paid preparer with a valid PTIN can prepare federal returns. Professional support still lowers risk on Form 1120-S, K-1s, payroll and reasonable compensation.
What can a CPA do that an EA can't for an S Corp?
A CPA may provide eligible attest services such as audits or reviews, plus broader accounting. EAs specialise in tax and IRS representation. Actual services vary by practitioner.

Yes. EAs can prepare S Corp returns and represent clients in audits, collections and appeals. Confirm your engagement covers each, plus state matters.
How much does it cost to hire a CPA or EA for an S Corp?
Fees depend on bookkeeping quality, transaction volume, state filings, payroll, shareholder complexity and cross-border issues. Compare written flat-fee or package proposals from several providers.
