All About A Practical Guide Gift and Estate Tax Valuation
Comprehensive gift and estate tax valuations to ensure compliance and unlock smarter planning opportunities.
If you own a business, hold significant assets, or plan to pass wealth to the next generation, 2026 is shaping up to be one of the most important tax planning years of the decade. The federal lifetime gift and estate tax exemption, currently sitting near historic highs, is scheduled to drop sharply after December 31, 2025. For business owners and high-net-worth individuals, this creates both urgency and opportunity.
At the heart of every effective wealth transfer plan is one critical process: gift and estate tax valuation. Whether you are gifting shares to your children, establishing a trust, or preparing your estate for eventual transfer, the value assigned to your assets determines how much tax you or your heirs will owe, and how much of your legacy will stay intact.
This guide walks you through everything you need to know, from the fundamentals of valuation and the approaches used by professional appraisers, to the discounts that can meaningfully reduce your tax liability, the mistakes that trigger IRS audits, and how to stay compliant throughout the process.

What Is Gift & Estate Tax Valuation?
Gift and estate tax valuation is the process of determining the fair market value of assets transferred either during a person’s lifetime or after their death, so that the correct amount of tax can be calculated and reported to the IRS. Without an accurate valuation, you cannot file gift or estate tax returns correctly, and you expose yourself to penalties, interest, and audits.
Defining Fair Market Value (FMV)
Fair market value is the foundation of every valuation. The IRS defines it as the price at which an asset would change hands between a willing buyer and a willing seller, with neither being under compulsion to buy or sell, and both having reasonable knowledge of all relevant facts. In simpler terms, it is what your asset would realistically sell for on the open market today.
Gift Tax vs. Estate Tax vs. Inheritance Tax
Though often grouped together, these three taxes serve different purposes:

Current Federal Tax Rates and Thresholds
Federal gift and estate tax rates remain progressive, topping out at 40% for taxable amounts exceeding the lifetime exemption. While federal thresholds have increased, state-level taxes remain a significant factor. Inheritance tax, where applicable at the state level, typically starts around 10% and can reach up to 18% depending on the state and the recipient’s relationship to the deceased.
Why Business Owners Should Prioritize Valuation Now
For business owners, valuation is not just a tax formality. It is a strategic lever that shapes how much of your company’s value stays in your family and how smoothly ownership transitions occur.
Support Succession Planning
For family-owned businesses, valuation provides the clarity needed to distribute ownership fairly among children, spouses, and key employees. It also supports buy-sell agreements and generational wealth transfer plans.
Gain Strategic Business Insights
Beyond tax planning, a valuation reveals how your business is actually performing. It highlights strengths, uncovers weaknesses, and informs decisions around growth, financing, and exit planning.
Unlock Valuation Discounts
Professional valuations often apply legitimate discounts, such as those for lack of control or lack of marketability, which can reduce the taxable value of business interests by 20% to 40% or more.
Reduce IRS Audit Risk
Larger estates face significantly higher audit probability. A well-documented, professionally prepared valuation serves as your first line of defense, demonstrating your figures came from a recognized methodology.
Lock In Lower Valuations Before Appreciation
If your business is on a growth trajectory, gifting shares today at their current value means future appreciation happens outside your taxable estate. A company worth $5 million today that grows to $15 million can transfer that $10 million in growth entirely tax-free if structured correctly.
Key Factors That Influence Gift & Estate Tax Valuation
No two valuations are identical, because multiple variables shape the final number. Understanding these factors helps you anticipate how your assets will be valued and identify where discounts may apply.
Degree of Control Over the Asset
Owning 51% of a company is worth more per share than owning 10%, because control carries decision-making power. Minority interests are typically valued lower on a per-share basis.
Marketability of the Interest
Publicly traded shares can be sold in seconds. Shares in a closely-held private business cannot. This lack of liquidity reduces value, and the adjustment is reflected through marketability discounts.
Ownership Concentration and Relative Size
If ownership is spread across many shareholders, no single stake commands a control premium. Conversely, a concentrated block of ownership may be worth more because it carries influence over company direction.
Family-Held Interests and IRS Scrutiny
Transfers within families receive heightened attention from the IRS. The agency scrutinizes whether valuations reflect true arm's-length values or are artificially depressed to reduce tax.
Capital Gains Tax Implications
When assets are eventually sold by the recipient, capital gains taxes may apply based on the original cost basis or stepped-up basis. This downstream impact should factor into your valuation and gifting strategy.
Industry and Market Conditions
A business valued in a booming market will command a different figure than the same business in a recession. Appraisers account for broader economic conditions, industry trends, and comparable transactions.
Understanding Valuation Discounts
Valuation discounts are among the most powerful tools in gift and estate tax planning. Applied correctly, they can significantly reduce the taxable value of transferred interests while remaining fully compliant with IRS rules.
Discount for Lack of Control (DLOC)
When there is a lack of actual control over certain property, you need to consider this aspect while conducting the gift and estate tax valuation. When noncontrolling interests are part of the value of your property, you can take advantage of the discount for lack of control.
Discount for Lack of Marketability (DLOM)
The discount for lack of marketability refers to the fact that certain properties may not be readily available on the open market or the marketplace is small. The lack of marketability is one of the major considerations in gift and estate tax valuation.
Other Discounts May Include:
- Minority interest discounts
- Future interest discounts (for certain trusts)
Valuation discounts are powerful tools for gift and estate tax planning, offering significant potential for tax savings. However, their application requires careful consideration, professional expertise, and thorough documentation to withstand potential IRS scrutiny.

The Three Core Valuation Approaches
When determining the fair market value (FMV) of a business interest for gift or estate tax purposes, valuation professionals rely on three internationally accepted approaches as outlined in IRS Revenue Ruling 59-60: the Market Approach, the Cost Approach, and the Income Approach. Each approach views value from a different lens, and the most defensible valuation typically reconciles findings from more than one method.
1. Market Approach – Guideline Comparable Transaction Method
The Market Approach determines value by referencing prices paid in arm’s-length transactions for similar businesses. Under this approach, the Guideline Comparable Transaction Method (GCTM) examines actual merger and acquisition deals involving companies comparable to the subject entity. A valuation multiple — most commonly EV/EBITDA or EV/Revenue — is derived from these transactions and applied to the subject company’s financial metric.
This method is particularly relevant for gift and estate tax valuation because the IRS places strong emphasis on observable market evidence, which makes transaction-based valuations highly defensible during audit.

2. Cost Approach – Adjusted Net Asset Method
The Cost Approach values a business based on the fair market value of its underlying assets, net of liabilities. While book value reports assets at historical cost, the Adjusted Net Asset Method (ANAM) restates every balance sheet item to its current fair market value, revealing the true economic worth of the entity.
This approach is especially useful for holding companies, real estate entities, investment vehicles, and asset-heavy businesses — a common profile for entities being transferred in estate planning. It also serves as a “floor value” when reconciling with income and market approach results

3. Income Approach – Discounted Cash Flow (DCF) Method
The Income Approach, through the Discounted Cash Flow (DCF) method, values a business based on the present value of the future cash flows it is expected to generate. This is the most theoretically sound method for operating companies with predictable cash flows, and it is heavily relied upon in IRS-reviewed gift and estate tax valuations.
Where FCF = Free Cash Flow to Firm, WACC = Weighted Average Cost of Capital, and t = projection year.

Common Mistakes to Avoid in Gift & Estate Tax Valuation
Even well-intentioned plans can fall apart due to avoidable errors. Here are the most common pitfalls to sidestep.
Relying on Outdated or DIY Valuations
Using a rough estimate or an old valuation from years ago is one of the fastest ways to trigger an IRS challenge. Valuations should reflect current market conditions and recent financial performance.
Overlooking Applicable Valuation Discounts
Failing to apply legitimate discounts leaves significant tax savings on the table. Many business owners simply do not know which discounts apply to their situation.
Poor Documentation of Assumptions and Methodology
If your appraiser cannot clearly explain how they arrived at the final number, the IRS will not accept it. Documentation is the backbone of a defensible valuation.
Missing Filing Deadlines
Form 709 for gift tax is due by April 15 of the year following the gift. Form 706 for estate tax is generally due nine months after death. Missing these deadlines results in penalties and loss of certain elections.
Failing to Update Valuations After Business Changes
Major events such as a new funding round, an acquisition, or significant revenue growth can substantially change your business’s value. Old valuations quickly become obsolete.
Ignoring State-Level Estate and Inheritance Taxes
Federal planning is only half the picture. Several states impose their own estate or inheritance taxes, often with lower exemption thresholds than the federal government.
How to Stay IRS-Compliant During Valuation
Compliance is not optional. The IRS has specific expectations for how valuations should be prepared and reported, and meeting those standards protects you from costly disputes.
Maintain Thorough Documentation
Keep records of all assumptions, comparable transactions, financial statements, and communications with your appraiser. These materials may be needed years later if your return is audited.
File the Correct Tax Forms on Time
Form 709 reports taxable gifts, and Form 706 reports the estate of a deceased person. Filing accurately and on time is essential to avoid penalties.
Understand Adequate Disclosure Rules
Proper disclosure on your gift tax return starts the three-year statute of limitations, after which the IRS can no longer challenge the valuation. Without adequate disclosure, the IRS can revisit your valuation at any time, even decades later.
When to Get a Professional Valuation
Not every transaction requires a formal appraisal, but several situations absolutely do.
Planning a Gift of Business Interest
Any significant gift of business ownership, whether to family, employees, or trusts, should be supported by a professional valuation.
High-Net-Worth Estate Planning
If your total estate is likely to exceed the federal or state exemption, proactive valuation is essential to minimize future tax exposure.
Setting Up Trusts & Advanced Structures
Grantor Retained Annuity Trusts (GRATs), Intentionally Defective Grantor Trusts (IDGTs), and dynasty trusts all require baseline valuations to function correctly.
Common Questions
Frequently Asked Questions
Gift tax applies to transfers made during your lifetime, while estate tax applies to transfers after death. Both share the same lifetime exemption and tax rates ranging from 18% to 40%.
