Many taxpayers first seek professional assistance after receiving an IRS notice, audit letter, or other correspondence from the Internal Revenue Service. One of the first questions they ask is whether they should work with a tax preparer, a Certified Public Accountant (CPA), an Enrolled Agent (EA), or a tax attorney.

The answer depends upon the nature of the tax controversy.

For many routine tax compliance matters, a qualified CPA or Enrolled Agent may provide excellent assistance. However, as an IRS examination becomes more complex and begins to involve disputed legal issues, procedural questions, significant proposed tax adjustments, or potential litigation, representation by a tax attorney may offer important additional advantages.

Understanding these differences can help taxpayers make informed decisions before an IRS dispute becomes more difficult and expensive to resolve.

Who May Represent Taxpayers Before the IRS?

The IRS authorizes several categories of professionals to represent taxpayers in administrative matters.

Tax Attorneys

Tax attorneys are licensed lawyers who concentrate on federal and state tax law. In addition to representing taxpayers before the IRS during examinations and administrative proceedings, tax attorneys may continue representing clients in court when litigation becomes necessary.

Their training includes statutory interpretation, legal research, procedural rules, evidentiary principles, negotiation, and litigation.

Certified Public Accountants (CPAs)

Certified Public Accountants possess extensive knowledge of accounting principles, financial reporting, and taxation. They routinely prepare tax returns, advise clients regarding tax planning, and represent taxpayers during IRS examinations.

Their accounting expertise often plays an essential role in explaining financial records, reconstructing transactions, and analyzing complex tax calculations.

Enrolled Agents (EAs)

Enrolled Agents are federally authorized tax professionals licensed to practice before the Internal Revenue Service. Many have significant experience preparing tax returns and representing taxpayers during IRS examinations and other administrative proceedings.

Enrolled Agents provide valuable assistance in a wide variety of federal tax matters.

Every Professional Plays an Important Role

Each of these professionals serves an important function within the tax system.

The difference is not that one credential is universally “better” than another. Rather, the nature of the controversy often determines which professional qualifications become increasingly important as the matter progresses.

When an Accounting Matter Becomes a Legal Controversy

Many IRS examinations begin with accounting questions.

The IRS may request:

• Additional documentation
• Bank records
• Business records
• Receipts
• Contracts
• Closing statements
• Accounting schedules

At this stage, accounting knowledge is often central to resolving the examination.

However, some disputes evolve beyond accounting.

The disagreement may involve questions such as:

• The proper interpretation of the Internal Revenue Code
• Treasury Regulations
• Judicial decisions interpreting federal tax law
• Procedural requirements imposed upon the IRS
• The burden of proof
• Penalty defenses
• Evidentiary issues
• Statutory deadlines

As these legal issues become more significant, legal analysis frequently becomes just as important as accounting analysis.

Additional Advantages a Tax Attorney May Provide

Legal Analysis

Federal tax law is far more than preparing tax returns.

Resolving many tax controversies requires careful analysis of statutes, Treasury Regulations, IRS administrative guidance, judicial precedent, and procedural rules.

A tax attorney is trained to analyze and apply these legal authorities when developing arguments on behalf of a client.

Strategic Case Development

Every decision made during an IRS examination can affect later stages of the controversy.

Documents produced during an audit, written explanations submitted to the IRS, factual admissions, and legal positions taken early in the process frequently become part of the administrative record.

A tax attorney evaluates not only the immediate response to the IRS but also how today’s decisions may affect tomorrow’s negotiations, appeals, or litigation.

Procedural Strategy

Federal tax controversies are governed by procedural rules as well as substantive tax law.

Understanding deadlines, preserving procedural rights, evaluating available administrative remedies, and determining the appropriate litigation strategy often become critical as a case develops.

These procedural considerations frequently influence the outcome of a dispute.

Representation Beyond the IRS Audit

One of the most significant distinctions involves continuity of representation.

Many taxpayers assume an IRS audit represents the final stage of the process.

In reality, an audit is often only one phase of a broader federal tax controversy.

Depending upon the circumstances, representation may continue through several stages, including:

• IRS correspondence
• Correspondence audits
• Office audits
• Field examinations
• Administrative conferences
• IRS Independent Office of Appeals
• Collection-related proceedings where applicable
• United States Tax Court litigation when appropriate

Developing a consistent strategy across each stage often places the taxpayer in a stronger position than treating every stage as an entirely separate matter.

The United States Tax Court

If an acceptable resolution cannot be reached administratively, some taxpayers may have the right to petition the United States Tax Court after the IRS issues a statutory Notice of Deficiency.

The United States Tax Court is an independent federal court that resolves tax disputes between taxpayers and the Internal Revenue Service.

One important feature of Tax Court litigation is that eligible taxpayers generally may challenge the proposed deficiency before paying the disputed tax, provided the petition is filed within the applicable statutory deadline.

A tax attorney may continue representing the client throughout this judicial process, providing continuity from the initial IRS examination through litigation when necessary, including representation before the United States Tax Court.

Attorney-Client Communications

As a controversy becomes more complex, taxpayers often wish to discuss sensitive legal issues, possible litigation risks, procedural concerns, and settlement strategy.

Obtaining legal advice early in the process allows taxpayers to better understand their rights, available options, and the potential consequences of various strategic decisions before responding to the IRS.

Why Continuity Matters

One challenge that sometimes arises during lengthy tax controversies is the need to transition from one professional to another as the case becomes increasingly complex.

Changing representatives may require:

• Reviewing years of tax returns
• Reconstructing factual history
• Reexamining financial records
• Developing a new legal strategy
• Becoming familiar with prior communications with the IRS

Continuity of representation allows the professional handling the matter to understand the case from the beginning and continue advocating for the taxpayer if the controversy progresses beyond the audit stage.

Situations Where a Tax Attorney May Be Particularly Beneficial

Representation by a tax attorney may be particularly valuable in matters involving:

• Large proposed tax deficiencies
• Multi-year IRS examinations
• Business tax controversies
• Partnership and corporate disputes
• International tax reporting
• Foreign financial account issues
• Significant penalties
• Payroll tax disputes
• Complex legal questions
• IRS Independent Office of Appeals
• United States Tax Court litigation

Every case is different, and the appropriate strategy depends upon the specific facts and applicable law.

Strategic Takeaway

Every IRS tax controversy begins with questions about the correct application of federal tax law. Some disputes remain primarily accounting matters and may be resolved through the administrative examination process. Others develop into more significant legal controversies requiring careful procedural planning, legal analysis, and, in some cases, litigation.

Certified Public Accountants, Enrolled Agents, and tax attorneys each provide valuable professional services. However, when an IRS dispute becomes increasingly complex or progresses beyond the examination stage, representation by a tax attorney may provide important additional advantages, particularly where legal analysis, procedural strategy, administrative appeals, or judicial proceedings become necessary.

As both a Certified Public Accountant (CPA) and Attorney (JD), I represent individuals, business owners, investors, and professionals throughout the federal tax controversy process—from tax return analysis and IRS examinations to representation before the IRS Independent Office of Appeals and, when appropriate, litigation before the United States Tax Court. My objective is to provide continuity of representation, protect my clients’ procedural rights, and develop a comprehensive strategy designed to achieve the strongest possible outcome.

Receiving an IRS audit notice is often the beginning—not the end—of a federal tax dispute.

Many taxpayers mistakenly believe that once the Internal Revenue Service completes an examination, the IRS’s conclusions are final and must simply be accepted. Others assume that their tax preparer can assist during the audit but that a separate attorney must be retained if the dispute continues beyond the examination stage.

In reality, federal tax controversies frequently involve multiple administrative and judicial stages. A taxpayer’s strategy should be developed with the entire process in mind, not merely the initial audit.

Whether the issue involves an individual income tax return, California residency audits, a closely held business, international reporting obligations, payroll taxes, or complex real estate transactions, understanding the available procedural options can significantly affect the outcome.

The IRS Audit Is Often Only the Beginning

An IRS examination is designed to determine whether a tax return has been prepared correctly.

During the audit, the IRS may request documentation, interview the taxpayer or the taxpayer’s representative, and propose adjustments to income, deductions, credits, basis, depreciation, or other tax items.

Many examinations conclude without significant disagreement.

Others, however, result in proposed assessments that the taxpayer believes are legally or factually incorrect.

When that occurs, taxpayers still have important procedural rights.

Administrative Resolution Before Litigation

One of the most important aspects of federal tax practice is recognizing that litigation is rarely the first step.

Before a case reaches court, many disputes proceed through administrative review within the IRS.

Depending upon the circumstances, representation may include:

• Responding to IRS Information Document Requests (IDRs)
• Preparing legal and factual submissions
• Organizing supporting documentation
• Negotiating with IRS revenue agents
• Identifying procedural errors
• Presenting applicable statutes, regulations, and judicial authority
• Seeking administrative resolution before formal litigation becomes necessary

Many disputes are resolved during these administrative stages.

The IRS Independent Office of Appeals

If an examination cannot be resolved with the IRS examiner, taxpayers may have the opportunity to present their case to the IRS Independent Office of Appeals.

Appeals serves a different function than the examining division.

Rather than conducting another audit, Appeals evaluates the strengths and weaknesses of each party’s legal position and considers the hazards of litigation if the dispute were eventually presented to a court.

Appeals frequently considers:

• Applicable statutes
• Treasury Regulations
• IRS administrative guidance
• Judicial precedent
• The quality of the available evidence
• Litigation risk for both parties

Many federal tax controversies are successfully resolved during the Appeals process without requiring court proceedings.

When Tax Court Becomes Necessary

Not every dispute can be resolved administratively.

When the IRS issues a statutory Notice of Deficiency and an acceptable administrative resolution cannot be reached, taxpayers may petition the United States Tax Court.

One significant advantage of the United States Tax Court is that taxpayers generally may challenge the proposed deficiency before paying the disputed tax, provided the petition is timely filed.

The Tax Court independently reviews both the facts and the applicable law.

It is not simply another division of the IRS.

Instead, it is an independent federal court established to resolve tax disputes between taxpayers and the government.

Why Early Strategy Matters

One of the most common mistakes taxpayers make is viewing each stage independently.

They respond to the audit without considering how those responses may later affect Appeals or litigation.

Statements made during an examination, documents produced early in the process, and positions taken before the IRS often become part of the administrative record that follows the taxpayer throughout the controversy.

For that reason, strategic planning should begin before the first substantive response is provided to the IRS.

The Advantage of Combined CPA and Attorney Representation

Federal tax controversies frequently involve two separate disciplines.

The first is accounting.

Questions involving income recognition, depreciation, basis calculations, business deductions, payroll records, financial statements, and accounting records require technical tax expertise.

The second is law.

Disputes may require statutory interpretation, legal research, procedural analysis, evidentiary evaluation, administrative advocacy, and, when necessary, litigation before the United States Tax Court.

Having representation that combines both disciplines can provide continuity throughout the entire controversy process.

Rather than transferring the case from one professional to another as the matter becomes more complex, taxpayers benefit from representation that understands both the accounting issues and the legal framework from the beginning.

Comprehensive Representation From Beginning to End

Federal tax controversies rarely fit neatly into a single category.

A matter that begins as a routine correspondence audit may later involve legal arguments concerning statutory interpretation, administrative procedure, or evidentiary issues.

Comprehensive representation may therefore include:

• Tax return analysis
• Audit representation
• IRS correspondence
• Administrative negotiations
• IRS Independent Office of Appeals representation
• Penalty defense
• Collection-related guidance
• United States Tax Court litigation when appropriate

Developing a consistent strategy across every stage often places taxpayers in a stronger position than addressing each stage independently.

Strategic Takeaway

An IRS audit should not be viewed as an isolated event. It is often the first phase of a broader federal tax controversy process with multiple administrative and judicial stages.

Understanding those stages before responding to the IRS allows taxpayers to make informed decisions, preserve important procedural rights, and develop a strategy that remains consistent from the initial examination through final resolution.

As both a Certified Public Accountant (CPA) and Attorney (JD), I represent individuals, business owners, investors, and professionals throughout the federal tax controversy process—from IRS examinations and administrative appeals to, when appropriate, litigation before the United States Tax Court.

Whether your matter can be resolved during the audit or requires further administrative or judicial review, experienced representation at every stage can help protect your rights and position your case for the strongest possible outcome.
