How to choose a tax relief company

Tax relief can be worth the cost for the right case, but the industry has a mixed reputation. Use this checklist before you sign anything.

  1. Confirm who will actually work your case

    Ask whether your representative is an attorney, CPA, or enrolled agent, and ask for their license number. Credentials you can verify are the single best predictor of a legitimate firm.

  2. Get every fee in writing

    Reputable firms quote a clear fee for a defined scope of work. Ask what is charged up front, what is charged later, and what happens to your money if the case does not move forward.

  3. Ask what outcomes are realistic

    A good representative explains your options, including payment plans, penalty abatement, and Offers in Compromise, and tells you plainly which ones you may qualify for.

  4. Check independent reviews and complaints

    Look at Better Business Bureau records, Google and Trustpilot reviews, and your state attorney general's complaint database. Pay attention to how the company responds to problems.

Red flags to walk away from

  • Guaranteeing a specific settlement amount or promising to “settle for pennies on the dollar”
  • Demanding a large payment before reviewing your IRS transcripts
  • Pressuring you to sign the same day or claiming a limited-time program
  • Refusing to name the licensed professionals who will handle your case
  • Telling you to stop communicating with the IRS without explaining why

You can also contact the IRS directly at no cost. See our Tax Help Center for the options available without a representative.

Frequently asked questions

What is the best tax relief company?

Based on our 2026 evaluation, Calculus Tax is our top-ranked tax relief company overall, followed by nomo.tax and Optima Tax Relief. The right choice depends on your balance: Optima and Community Tax suit large or complex cases, while nomo.tax and PastDu are better for smaller debts and budget-conscious taxpayers.

How much does tax relief cost?

Most reputable tax relief companies charge between roughly $1,500 and $18,000, depending on the size and complexity of the case. Simple cases such as a payment plan or penalty abatement typically fall at the low end, while Offers in Compromise, multi-year cases, and business tax problems cost more. Always get fees in writing before signing.

Are tax relief companies legitimate?

Many are, but the industry also has bad actors. A legitimate firm employs licensed professionals (attorneys, CPAs, or enrolled agents), explains your options honestly, never guarantees a specific result, and puts fees in a written agreement. Check Better Business Bureau records, state bar or CPA licenses, and Treasury Circular 230 standing before you pay anything.

Can I resolve IRS debt without paying a tax relief company?

Yes. You can apply for an installment agreement, Offer in Compromise, penalty abatement, or Currently Not Collectible status directly with the IRS at no cost. A tax relief company is most valuable when your case is complex, you are facing enforced collection, or you cannot afford to spend the time managing it yourself.

How long does tax relief take?

Simple payment plans can be approved in a few weeks. An Offer in Compromise commonly takes six to twelve months, and complex multi-year or business cases can take longer. A good representative can usually stop active collection, such as levies and garnishments, much sooner than the final resolution.

How does Top Ten Tax rank companies?

We score every company out of 100 across four weighted categories: resolution outcomes (35%), customer feedback (25%), credentials (20%), and pricing and transparency (20%). Rankings are reviewed regularly and are not influenced by payment for placement.
