Estate Tax Litigation: 4 Top Issues for Navigating Wealth Transfer Disputes

Oct 6, 2025 | Estate Tax

Estate planning is designed to bring clarity and peace of mind, making sure assets are distributed according to a person’s wishes while reducing tax burdens. When significant estates are involved, disputes with the Internal Revenue Service or state taxing authorities can arise. Estate tax litigation is resolving these conflicts — often in court — when assessments, valuations, or deductions are challenged.

For families and businesses, estate tax disputes are about more than numbers. These disputes affect financial security, family relationships, and the preservation of wealth for future generations. Whether representing an estate against government claims or defending a tax position in litigation, preparation and strategy are critical.


The Nature of Estate Tax Litigation

The federal estate tax applies to transfers of wealth at death when the estate exceeds the exemption amount. Some states also impose their own estate or inheritance taxes. Litigation often arises because calculating estate tax liability is rarely straightforward. Common points of conflict include:

  • Valuation of Assets: Real estate, closely held businesses, artwork, or investment portfolios may be difficult to value, and disagreements between the estate and the IRS can lead to litigation.
  • Applicability of Deductions: Charitable contributions, debts, and administrative expenses may be challenged.
  • Use of Discounts: Estates may apply valuation discounts for lack of marketability or control, especially for family-owned businesses. The Internal Revenue Service often scrutinizes these discounts.
  • Transfers Prior to Death: Gifts or transfers made shortly before death can be reclassified as part of the taxable estate.

Each issue can trigger audits, administrative appeals, and ultimately, courtroom battles.


Why Estate Tax Litigation Matters

The stakes in estate tax litigation are high. Litigation outcomes can determine whether heirs keep family businesses, maintain liquidity, or are forced to sell significant assets to satisfy tax obligations. For estates involving illiquid assets — such as farms, partnerships, or privately held companies — litigation can have lasting impacts on both finances and legacies.

Beyond financial exposure, estate tax litigation can also cause emotional strain. Family members may disagree on strategy, or disputes can exacerbate existing tensions. A clear legal roadmap helps reduce uncertainty and manage both financial and personal risks.


Key Issues in Estate Tax Litigation

1. Valuation Battles

Valuation is the cornerstone of most estate tax cases. The Internal Revenue Service often challenges appraisals from the estate, arguing that assets are undervalued to reduce tax liability. Experts play a central role, with appraisers and economists presenting competing evidence on fair market value.

2. Deduction Disputes

The estate may claim deductions for expenses like legal fees, debts, or charitable gifts. The Internal Revenue Service may question whether these deductions are legitimate, properly documented, or appropriately distributed.

3. Discount Controversies

Family-owned businesses often claim discounts to reflect the reduced market value of minority ownership stakes or lack of liquidity. These discounts can significantly reduce estate tax liability, but they are a frequent source of challenge by taxing authorities.

4. Procedural Defenses

Sometimes, estates may argue that the Service’s assessment was untimely or procedurally defective. Procedural defenses can provide powerful leverage, even when substantive issues remain in dispute.


Strategic Considerations

Just as in other forms of litigation, success in estate tax disputes depends on preparation and clear strategy. Some of the most effective approaches include:

  • Early Assessment: Understand the strengths and weaknesses of the estate’s position when an audit or challenge arises.
  • Preserve Documentation: Maintain thorough records of appraisals, expenses, and transactions. Proper documentation can make or break a case.
  • Engage Experts: Independent valuation experts, tax advisors, and economists provide essential evidence. Credible experts strengthen the estate’s position against government challenges.
  • Consider Settlement: Many estate tax disputes settle before trial. Exploring resolution through negotiation or mediation may save significant time and expense.
  • Align with Family Goals: Strategy should consider not only the potential tax savings but also family dynamics, business continuity, and long-term wealth preservation.

Business and Family Impacts

Estate tax litigation’s consequences extend beyond the courtroom:

  • Liquidity Strain: Estates may need to sell assets or borrow funds to pay taxes during prolonged disputes.
  • Operational Disruption: Family businesses tied up in litigation may face uncertainty that affects employees, suppliers, and customers.
  • Reputational Concerns: Public disputes can affect family privacy and standing in the community.
  • Future Planning: Litigation outcomes often influence how families approach future estate planning strategies.

These ripple effects highlight why estate tax litigation should be discussed with both legal precision and business foresight.


Conclusion

Estate tax litigation is complex, high-stakes, and personal. Valuation disputes, deduction challenges, and discount controversies can expose estates to significant tax liability. By preparing thoroughly, engaging expert advisors, and aligning strategy with family and business goals, estates can navigate these disputes more effectively.

While litigation may sometimes be unavoidable, proactive planning and experienced legal guidance can help reduce risks. For families and businesses facing estate tax disputes, a clear strategy provides financial protection and peace of mind during a difficult and often emotional process.
