CPA vs Tax Preparer Cost Calculator (PTIN, EA, CPA)
Deciding between a CPA and a tax preparer? Enter the fee each one quoted you for the same return and say whether you want someone who can represent you before the IRS. The calculator picks the lowest quote that meets your need and shows what the extra credential costs. Preparer fees vary by return and by town, and no official price list exists, so this page uses only the quotes you enter.
A CPA and tax preparer comparison is really a comparison of credentials. Anyone paid to prepare federal returns must hold a Preparer Tax Identification Number (PTIN), but a PTIN alone is a registration, not a qualification. Enrolled agents and certified public accountants hold credentials that also let them represent you before the IRS. This calculator compares the quotes you collected and shows what that extra right costs.
CPA and tax preparer credentials compared
| Preparer | What the credential is | Right to represent you before the IRS |
|---|---|---|
| PTIN-only preparer | Registered with the IRS; no credential | None. No authority to represent clients, apart from returns filed before 2016 |
| Annual Filing Season Program participant | Voluntary IRS continuing-education record | Limited: only for returns they prepared and signed, and only before revenue agents, customer service representatives and similar IRS employees |
| Enrolled agent (EA) | Federal credential issued by the IRS | Unlimited: audits, payment and collection issues, appeals |
| Certified public accountant (CPA) | State licence | Unlimited: audits, payment and collection issues, appeals |
| Attorney | State bar licence | Unlimited: audits, payment and collection issues, appeals |
The IRS charges preparers $18.75 to obtain or renew a PTIN, so the registration itself says nothing about skill. All enrolled agents must also hold a valid PTIN.
Worked example: comparing three quotes
Suppose a PTIN-only preparer quotes $220, an enrolled agent $350 and a CPA $500 for the same return. If you want representation rights, the lowest qualifying quote is the enrolled agent at $350. The credential costs $130 more than the PTIN-only quote, and the CPA is $150, or 42.86%, more than the enrolled agent. If you only need the return prepared, the PTIN-only preparer at $220 is the lowest. These three figures are an illustration, not typical prices.
How to get comparable quotes
Ask each preparer to price the same work: the same federal forms and schedules, the same number of state returns and any bookkeeping clean-up. Ask whether audit help is included or billed by the hour, and whether the fee is fixed. Check credentials in the IRS Directory of Federal Tax Return Preparers with Credentials and Select Qualifications. A CPA may be worth more if you also need financial statements or business advice; an enrolled agent specialises in tax.
What this tool does not do
It does not estimate what a preparer should charge, and it does not rate quality. It ranks the quotes you enter against the representation rights the IRS describes for each credential.
