How do I evaluate whether a tax prep service is credible and unbiased?

To judge whether a tax prep service is credible and unbiased, look for a mix of credentials, transparency, incentives, and track record.

1) Check qualifications and registration

• CPA, EA, or tax attorney: These are the strongest professional credentials.
• Ask whether the preparer has a PTIN (Preparer Tax Identification Number) and whether they’re authorized to e-file.
• If applicable, verify licensure through your state board or the IRS directory.

2) Look for independence and conflicts of interest

A service may not be unbiased if it:

• Earns commissions from products they recommend
• Pushes refund anticipation loans, audit defense plans, or financial products
• Has incentives to steer you to a specific filing method or refund product

Ask:

• “How are you paid?”
• “Do you receive commissions or referral fees?”
• “Do you have any financial relationship with the products you recommend?”

3) Evaluate how they handle your situation

A credible tax prep service should:

• Ask detailed questions about income, deductions, dependents, and prior filings
• Explain why they’re taking each position
• Flag uncertain items and ask for documentation
• Be willing to say, “I don’t know, but I’ll research it”

Red flags:

• They promise the “biggest refund”
• They rush through the return
• They don’t review supporting documents
• They discourage questions or won’t explain entries

4) Assess accuracy and review process

Ask if they:

• Use a documented review checklist
• Have a second preparer review the return
• Provide you with a copy of the completed return before filing
• Are available after filing for notices or questions

A good service should be willing to show you the final numbers and where they came from.

5) Check reputation, but interpret carefully

Look at:

• Better Business Bureau complaints
• State licensing board actions
• Online reviews for patterns, not one-off comments
• IRS or state disciplinary history if available

Be cautious with flashy testimonials or “guaranteed refund” marketing.

6) Understand their advice style

Credible preparers distinguish between:

• Tax law facts
• Interpretation
• Aggressive positions

They should explain risk levels, not just optimize for the largest refund.

7) Ask about audit support

A trustworthy service should tell you:

• What support they provide if the IRS contacts you
• Whether that support is included or extra
• Whether they stand behind the return preparation

8) Use a simple screening question set

You can ask:

1. What are your credentials?
2. How are you compensated?
3. Do you have any commissions or referral fees?
4. How do you review returns for accuracy?
5. What happens if the IRS questions my return?
6. Will you explain any deduction or credit you claim?

If they answer clearly and directly, that’s a good sign.
