The safest way to avoid a tax-preparer scam is to verify the preparer’s PTIN and credentials, insist that the preparer signs the return, review every line before authorizing filing, and keep the refund directed to your own bank account. Refuse to sign a blank return, question promises of unusually large refunds, and walk away from fees based on a percentage of your refund. You remain legally responsible for the information filed in your name, even when someone else prepared it.
What are the biggest tax-preparer red flags?
The most serious warning signs are a missing PTIN or signature, a request to sign a blank or incomplete return, guaranteed or surprisingly large refund claims, fees tied to the refund amount, unsupported credits or deductions, and a demand to route your refund through the preparer’s account. Other concerns include refusing to provide a complete copy, asking for cash without a receipt, requesting little or no documentation, or becoming unreachable after filing.

These signs do not all prove fraud by themselves. They do indicate that you should pause, ask for evidence, verify the preparer’s qualifications and never authorize filing until the completed return is accurate. The IRS says a preparer who refuses to sign or provide a PTIN is a major red flag, and reminds taxpayers that they are legally responsible for what is filed.
How can I verify a paid preparer’s PTIN and signature?
A paid federal tax preparer must have a current Preparer Tax Identification Number (PTIN) and include it on returns they prepare. The preparer also must sign the return. Treat the actual completed return—not a verbal promise—as your evidence.

- Ask for the preparer’s legal name and PTIN. A legitimate preparer should provide the information without hesitation.
- Look at the signature section on the completed return. The preparer’s name, signature and PTIN should appear where required. A “ghost preparer” who leaves the paid-preparer section blank is a major warning sign.
- Confirm who actually prepared the return. A firm may have several employees; identify the person responsible for your return, not only a receptionist or salesperson.
- Do not accept a substitute. A business card, invoice or handwritten number is not a replacement for a valid PTIN and signed return.
PTIN status and professional credentials are different questions. A PTIN authorizes paid preparation of federal returns but does not, by itself, make someone a certified public accountant, attorney or enrolled agent. The IRS explanation of preparer credentials describes which professionals have unlimited representation rights before the IRS. Attorneys, CPAs and enrolled agents generally have those unlimited rights; other preparers’ ability to represent you is narrower and depends on their qualifications and the matter involved.
The IRS maintains a directory of certain credentialed professionals and Annual Filing Season Program participants. Not appearing in that directory is not proof that a person is dishonest or incompetent, so use it as one verification step rather than a pass/fail test.

Signing an incomplete return gives someone else the opportunity to add income, deductions, credits, bank details or other information after you have approved it. Never sign a return until every page and schedule is complete and you have had time to read it.
Ask the preparer to explain anything that is unclear, inconsistent with your records or unexpectedly favorable. If the explanation does not make sense, take the return away for a second opinion or choose another preparer. Electronic filing does not remove this responsibility: review the final Form 1040 and attached schedules before entering a PIN, signing electronically or authorizing transmission.
Keep a complete copy of the filed return, all schedules and the documents you supplied. The IRS and Taxpayer Advocate Service both recommend retaining your copy because you may need it to answer an IRS notice, amend an error or show what you authorized.
How should I evaluate refund promises and tax-break claims?
A refund is the result of your income, withholding, estimated payments and legitimate credits and deductions—not a prize a preparer can guarantee in advance. Be especially cautious when a preparer quotes a large refund before reviewing your records or says every client qualifies for the same credit.

- Guaranteed results: No ethical preparer can know your final refund without complete, accurate information and the applicable tax rules.
- Refunds that suddenly grow: Ask which line items changed and what documents support them.
- Unsupported credits: Credits have eligibility rules involving income, dependents, filing status, work, education or other facts. A preparer should ask questions and request records, not tell you to invent facts.
- Inflated deductions: Deductions should reflect expenses you actually incurred and can substantiate. Do not accept a deduction merely because it increases the refund.
- Pressure to omit income: Income reported on Forms W-2, 1099 and other information returns must be reconciled. Omitting a form can create an IRS notice, tax bill, penalties or interest.
The IRS’s guidance on ghost preparers and tax-credit scams urges taxpayers to be informed rather than persuaded by an attractive number. You—not the preparer—sign the return under penalties of perjury, so decline any entry you cannot support.
Are refund-based fees a warning sign?
Yes. The IRS advises taxpayers to avoid preparers who charge a percentage of the refund. That pricing model gives the preparer an incentive to inflate credits or deductions. Ask for the fee basis in writing before work begins: a flat fee, an hourly rate, or another clearly defined method is easier to evaluate than “we take a share of whatever you get back.”
Request an itemized invoice showing preparation, e-filing and any optional services separately. Be wary of unexplained charges, cash demands without a receipt or charges for work that was not performed. A low upfront quote that expands after the refund is calculated is not a transparent fee arrangement.
How do I protect my refund and bank information?
Your refund should go to an account you control. Before authorizing e-file, inspect the bank routing and account numbers on the completed return and any related bank-product paperwork. Confirm that the account is in your name or jointly held by you—not an account controlled by the preparer.
Recommended Free Tools
A preparer who insists that the refund must be deposited into their account, refuses to show the routing details or says the arrangement is “standard” is giving you a reason to stop. Do not hand over online-banking passwords, debit-card credentials or one-time security codes. If a preparer offers a refund-advance or other financial product, read its separate disclosures and costs; it should never require surrendering control of your tax refund without your informed consent.
Check the routing information again after any correction or amendment. A single transposed digit can delay a payment, while an account controlled by someone else can divert it entirely.

What records should a legitimate preparer request?
A responsible preparer asks questions and requests documents that match your situation. Typical records can include wage and income forms, retirement or investment statements, self-employment income and expense records, mortgage or education statements, charitable receipts, health-insurance information and prior-year returns. The exact list depends on your circumstances.
“Upload nothing; I can get you a bigger refund from memory” is not a professional shortcut. A preparer who never asks about dependents, filing status, income sources or major life changes cannot reasonably verify eligibility. Conversely, a request for sensitive documents should come through a secure process, and you should understand why each item is needed.
Organize the documents you provide and keep copies. Do not destroy original receipts or records merely because a preparer scanned them. If the preparer refuses to return your documents or will not tell you how they are stored, consider using someone else.
What should I check before signing or authorizing e-file?
Use this review sequence after the return is complete and before you sign Form 8879 or otherwise authorize electronic filing.
- Read every page and schedule. Do not review only the refund summary. Schedules often contain the entries that drive your tax.
- Verify identity details. Check names, Social Security numbers or ITINs, addresses, filing status and dependent information.
- Match income to your records. Compare wages, interest, dividends, retirement distributions, gig income and other forms with what appears on the return.
- Check deductions and credits. Confirm that each item is yours, accurate and supported by records. Ask for a plain-language explanation of unfamiliar lines.
- Inspect payment or refund amounts. If you owe, verify the payment date and account. If you are due a refund, verify routing and account numbers.
- Confirm the preparer’s signature and PTIN. Make sure the person who prepared the return signs it and provides the PTIN where required.
- Ask for a complete copy. Obtain the final filed version, including all schedules, forms and authorization records.
- Authorize only after corrections. If anything is wrong, require a corrected return before signing or transmitting it.
The IRS Topic 254 guidance and the Taxpayer Advocate Service’s preparer-selection advice support these checks. A preparer who discourages questions or says “just sign here” is not giving you a meaningful review opportunity.
How do I compare two tax preparers?
Compare practical safeguards, not just the advertised refund or the lowest quote. Ask each candidate the same questions and record the answers.
Also popular on Amazon
| What to compare | Questions to ask | What a safer answer looks like |
|---|---|---|
| Credential and representation rights | What credential do you hold, and can you represent me before the IRS if there is a dispute? | A specific, verifiable credential and a clear explanation of its limits. |
| Documentation | Which records will you need from me? | A request tailored to your income, deductions and life circumstances. |
| Fees | How is the fee calculated, and can I receive an itemized quote? | A transparent basis that does not depend on the refund amount. |
| Signature and PTIN | Will you sign the return and show your PTIN? | A direct yes and a completed return displaying both as required. |
| Refund control | Where will my refund be deposited? | Your own verified account, with routing details shown before filing. |
| After-filing access | How can I reach you if the IRS sends a notice? | A documented contact method and a clear scope for post-filing help. |
Professional credentials can indicate training and representation rights, but they do not replace your review of the actual return. Likewise, an independent preparer can be competent even if not listed in the IRS directory; verify claims rather than assuming either approval or misconduct.
What should I do if the preparer refuses to sign, explain or provide a copy?
Stop the filing process and do not sign a blank or inaccurate return. Ask in writing for the missing signature, PTIN, explanation or copy. If the preparer will not comply, take your records and use a different professional; do not let a deadline or a promised refund pressure you into authorizing a return you cannot verify.
If a return was already filed, preserve the complete copy, engagement messages, invoices, receipts, bank details and any texts or emails. Write down dates, names and exactly what the preparer said. These records help you correct your account and provide specific information to investigators.

For suspected misconduct, the IRS directs taxpayers to Form 14157, Tax Return Preparer Complaint. Describe the conduct with concrete facts and attach relevant documentation as the current instructions require. Reports should be specific and credible rather than based only on suspicion.

An individual taxpayer may also qualify to use Form 14157-A, Tax Return Preparer Fraud or Misconduct Affidavit when a preparer altered tax data, diverted a refund or filed a Form 1040-series return without consent. Eligibility and filing steps can change, so follow the current form instructions. Form 14157 is the complaint route; Form 14157-A is for certain taxpayers seeking correction of an affected IRS account.
If the issue involves identity theft or a compromised account, follow the IRS identity-protection directions in addition to reporting the preparer. Notify your bank promptly about a misdirected refund and secure any reused passwords. Federal guidance does not replace state requirements: state preparer licensing and complaint procedures may differ, so check your state tax agency when the conduct involves state returns or local licensing.

Can I still be liable if my preparer made the mistake?
Yes. The taxpayer remains responsible for the information on the filed return, even when another person prepared it. A preparer’s error or misconduct does not automatically erase tax, interest or penalties that result from inaccurate information. Review before filing, keep supporting records and respond promptly to any IRS notice.
If you discover an error, contact the preparer and obtain an independent assessment. Depending on the facts, you may need to file an amended return, make a payment or submit documentation to the IRS. Do not let a preparer discourage you from correcting a known mistake.
A final decision rule before you sign
Proceed only when you can answer “yes” to all of these questions:
- Do I know who prepared the return and can I verify the person’s PTIN and claimed credentials?
- Is the return complete, accurate and supported by my records?
- Will the preparer sign it and provide a complete copy?
- Are the fees clear and unrelated to the size of my refund?
- Does the refund route to an account I control?
- Do I know how to reach the preparer after filing?
If any answer is “no,” pause and get the issue resolved or choose another preparer. A smaller refund from an accurate return is safer than a larger promised refund built on unsupported entries.
Frequently Asked Questions
Can a tax preparer legally refuse to give me a copy of my return?
You should receive a complete copy of the return and schedules prepared for you. If the preparer withholds it, request it in writing, preserve your other records and consider changing preparers; the missing copy is also relevant documentation if you report misconduct.
Does having a PTIN mean a preparer is an accountant or tax expert?
No. A PTIN is the federal identifier required for paid preparation, not a professional degree or unlimited right to represent clients. Verify whether the person is an attorney, CPA, enrolled agent or another type of preparer and understand the representation limits.

Contact your bank and the IRS promptly, preserve the filed return and communications, and review the current eligibility rules for Form 14157-A. Also submit a preparer complaint with Form 14157 when the facts support misconduct.
Should I use a preparer who says they can file without my records?
Treat that claim as a serious warning sign. A legitimate preparer needs enough documentation and questions to establish your income, deductions, credits and filing status; do not authorize entries you cannot substantiate.
