Tax Resolution Attorney in Longmont, Colorado

Receiving a letter from the IRS is stressful. Not knowing what it means or what to do next makes it worse. Nicole holds an LL.M. in Taxation from the University of Denver — which means when you call, you're talking to an attorney who actually specializes in tax law, not someone who handles it on the side.

Tax Matters We Handle

Nicole represents Colorado clients in a range of IRS and state tax situations. These are the most common:


  • IRS audit representation
  • Installment agreements
  • Offers in compromise
  • Penalty abatement requests
  • Back tax resolution
  • IRS levy and lien releases
  • Colorado Department of Revenue disputes



If you're dealing with something not on this list, call anyway. A brief conversation will clarify whether we can help and what the options look like.

Why an LL.M. in Taxation Makes a Difference Here

Most estate planning attorneys hold a standard J.D. Nicole also holds an LL.M. in Taxation — a graduate law degree focused specifically on tax law — from the University of Denver. It's the credential that separates tax law generalists from attorneys who have trained specifically in this area.


For tax resolution matters, that training means Nicole can read IRS correspondence accurately, identify the right resolution path for your situation, and represent you in negotiations with the IRS and the Colorado Department of Revenue.

Frequently Asked Questions

  • How can a tax attorney help with IRS debt in Colorado?

    A tax attorney can review your situation, identify the resolution options available to you — installment agreements, offers in compromise, penalty abatement, currently not collectible status — and represent you directly with the IRS so you don't have to manage the communication yourself. Having legal representation means the IRS deals with Nicole, not with you.

  • Do I need a tax lawyer for an IRS audit?

    You're not required to have one, but representation is strongly worth considering. An attorney who understands tax law can review the issues being examined, gather and present the right documentation, and communicate with the IRS on your behalf. Audits that start as straightforward reviews can expand in scope — having someone in your corner from the start limits that risk.

  • What's the difference between a tax attorney and a CPA for IRS issues?

    CPAs are well suited for tax preparation and financial analysis. A tax attorney brings legal training — attorney-client privilege, the ability to negotiate legally binding agreements with the IRS, and representation in tax court if needed. For straightforward tax questions, a CPA may be the right call. For IRS disputes, audits, or situations involving significant liability, an attorney with a tax law background is the stronger option.
