What an investigation fee actually buys

EXPLAINER

Most tax relief firms bill in two stages. First an investigation fee — commonly $295 to $495 — then a separate, larger resolution fee quoted afterwards. Almost nobody explains what the first payment actually buys.

It buys something real. It is also the single biggest obstacle to comparing firms on price, and understanding it changes how you shop.

What actually happens during the investigation

For your money, a firm should do four things:

  • File a Form 2848 power of attorney so it can deal with the IRS on your behalf.
  • Pull your account and wage transcripts for every relevant year.
  • Establish what you actually owe, for which periods, and where each sits in the collection process.
  • Assess which resolution programmes you plausibly qualify for, based on your finances.

That is genuinely useful work. A surprising proportion of people are wrong about their own tax situation — wrong about the amount, wrong about which years, wrong about whether the IRS has filed substitute returns on their behalf, and wrong about how close the collection statute is to expiring.

The output should be a clear picture and a recommendation. If it is not written down, ask for it in writing.

Why firms structure it this way

The charitable explanation is true: a firm genuinely cannot price the resolution work before it knows what the case involves. An offer in compromise for a self-employed filer with three unfiled years is not the same job as a straightforward instalment agreement, and quoting one price for both would be either overcharging or losing money.

The less charitable explanation is also true: two-stage billing converts a hesitant enquiry into a paying client at a low price point, after which the larger fee is being discussed with someone already invested. That is ordinary sales structure, not fraud, but it is worth naming.

Both things can be true at once, and mostly are.

The comparison problem

Here is what this does to shopping around. To get three comparable quotes for the actual work, you would have to pay three investigation fees — potentially over a thousand dollars — before you could compare anything.

Almost nobody does that. So people compare on the investigation fee, which is the small number, and then accept whatever resolution fee follows because they have already committed.

Two responses are worth considering:

  • Look for firms that quote the whole engagement flat at the consultation. They exist, and it makes genuine comparison possible.
  • Where a firm does bill in two stages, ask for a written resolution-fee estimate before paying the investigation fee, along with what would move it.

A firm that will not estimate the second number is asking you to sign a blank cheque for the larger of the two.

What you can do yourself, for nothing

Much of the investigation is available to you directly at no cost.

  • Create an IRS online account and view your balance by year.
  • Download account transcripts, which show assessments, payments and collection activity, and wage transcripts, which show what was reported about your income.
  • Ask the IRS directly for the collection statute expiration date on each period.
  • Run the IRS offer in compromise pre-qualifier, which applies a rough version of the settlement calculation for free.

Doing this before any consultation puts you in a different position entirely. You arrive knowing your balances, your assessment dates and roughly where you stand on an offer — which makes it obvious very quickly whether the person on the phone is telling you something you did not know.

What you are buying from a firm is interpretation and execution, not access. The data is yours already.

When paying for it is clearly worth it

  • Multiple years, especially with unfiled returns, where reconstructing the picture is genuinely complex.
  • A revenue officer assigned to your case, where the dynamic is active rather than automated.
  • Business or payroll tax, where trust fund recovery penalty exposure needs assessing before anyone says anything to the IRS.
  • Substitute returns filed on your behalf, where the assessed amount may be substantially overstated.
  • Any live collection action, where speed matters more than saving a few hundred dollars.

And when it probably is not

One or two years, returns filed, a balance you can pay over 72 months, and no collection action beyond notices. That is an online instalment agreement, and setting it up yourself takes about fifteen minutes.

Questions that expose a weak investigation offer

  • What specifically will I receive at the end — a document, a call, a written recommendation?
  • What is your estimate of the resolution fee, and what would change it?
  • Is the investigation fee credited against the resolution fee, or additional to it?
  • If you conclude I do not need representation, will you tell me — and does the fee cover that answer?
  • What are my collection statute expiration dates?

The fourth question is the revealing one. A firm willing to take your investigation fee and then tell you to handle it yourself is behaving well. A firm that has never once reached that conclusion is not investigating anything.

What a good investigation should tell you

By the end you should know your balance by year, your assessment dates and CSEDs, whether any returns are unfiled or were filed by the IRS on your behalf, where each period sits in the collection sequence, which programmes you plausibly qualify for, and what the realistic range of outcomes is — including the downside.

If what you receive instead is a phone call saying you qualify for a programme and a request for several thousand dollars, you have paid for a sales qualification rather than an investigation.

Common questions

Is the investigation fee refundable?

Sometimes, within a short window. Terms vary and some guarantees cover only this phase and not the resolution work. Read what the refund actually applies to.

Does it get credited toward the resolution fee?

At some firms yes, at others no. Ask explicitly, because it changes the real cost comparison.

Can I hire a different firm after the investigation?

Yes. You would revoke the power of attorney and engage someone else. You would likely pay a second investigation fee, which is precisely why the estimate question matters beforehand.

How long does it take?

Days to a few weeks, depending on how quickly transcripts come back and how complete your information is.
