Unit
- Tax controversy: A formal dispute between a taxpayer and the IRS regarding the correct amount of tax owed. It typically begins with an audit or a notice of deficiency. The practitioner must understand the procedural rules and strategic options available at each stage.
- Stages of a dispute: Controversies progress through audit, administrative appeal, and then litigation if unresolved. Each stage has distinct procedural rules, burdens of proof, and opportunities for resolution. The taxpayer's goals and risk tolerance influence the chosen path.
- Role of tax counsel: Attorneys and enrolled agents represent taxpayers before the IRS and in court. They must be skilled in factual analysis, legal research, and negotiation. Ethical duties include confidentiality, competence, and zealous representation within the bounds of the law.
- Comparison to civil litigation: Tax litigation follows specialized rules, such as the Tax Court Rules of Practice and Procedure. Unlike general civil courts, tax courts often hear cases without a jury, and the burden of proof may shift depending on the issue and the taxpayer's cooperation.
- Key statutory framework: The Internal Revenue Code and Treasury Regulations provide the substantive law. Procedural rules are found in Title 26 of the U.S. Code and the Federal Rules of Evidence. Understanding the interplay between these authorities is foundational for any tax practitioner.
- IRS structure: The IRS is organized into divisions including Large Business and International, Small Business/Self-Employed, and Tax Exempt and Government Entities. Each division has its own examination practices and appeal procedures that affect litigation strategy.
- Taxpayer Bill of Rights: Taxpayers have rights including the right to be informed, to challenge the IRS's position, and to a fair and just tax system. These rights guide the conduct of IRS personnel and provide a framework for advocacy during disputes.
- Importance of documentation: Thorough contemporaneous documentation of all communications with the IRS is critical. Written correspondence, notices, and notes from phone calls form the evidentiary record that may be used in litigation. Proper records reduce the risk of misunderstandings and substantiate the taxpayer's position.
Financial Formula
Statutory Interest on Underpayment
Interest = Tax Underpayment × (Federal Short-Term Rate + 3%) × (Days Late / 365)
Interest = Tax Underpayment × (Federal Short-Term Rate + 3%) × (Days Late / 365)
Where:
- Tax Underpayment: The amount of tax owed after applying payments and credits
- Federal Short-Term Rate: Determined quarterly by the IRS based on the average one-year constant maturity Treasury yield
- Days Late: Calendar days from the original due date of the return to the payment date
- Result: Interest compounded daily, added to the underpayment until paid in full
Regulatory Requirement
Regulation: IRC Section 6601
Section 6601 imposes interest on any underpayment of tax from the original due date of the return until the date paid. The rate is the federal short-term rate plus 3 percentage points, adjusted quarterly. This rule applies to all taxes assessed and collected under the Internal Revenue Code.
