Federal estate taxes represent one of the most significant financial threats to generational wealth transfer. For high-net-worth individuals and business owners in Houston, the stakes are particularly substantial. Without proactive planning, a taxable estate can face a federal tax rate of up to 40 percent on the value exceeding the applicable exemption threshold. That exposure can force the sale of business interests, real estate holdings, or investment assets at the worst possible time, simply to satisfy a tax bill. The good news is that with the right legal strategy in place well in advance, much of that liability can be reduced, deferred, or eliminated entirely.
At Quadros, Migl & Kilmer, our attorneys work with business owners, investors, and high-net-worth families to build tax-efficient estate plans that protect what they have accumulated and preserve it for the next generation. As a boutique Texas law firm with offices in Houston, The Woodlands, Dallas, and Austin, our team brings over 60 years of combined legal experience across estate planning, business law, and commercial transactions. Clients who need a sophisticated Houston estate planning lawyer capable of addressing the full complexity of their tax exposure will find a focused and capable partner in our firm.
Understanding the Federal Estate Tax
The federal estate tax applies to the transfer of a taxable estate from a decedent to their heirs. According to the IRS, an estate tax return is required when the gross estate exceeds the applicable filing threshold for the year of the decedent’s death, which can include the value of business interests, real estate, retirement accounts, and other assets. Any value above the exemption threshold is taxed at a top marginal rate of 40 percent.
The federal exemption amount has changed significantly in recent years. The One Big Beautiful Bill Act, signed into law in July 2025, made the expanded exemption permanent and increased it to $15 million per person beginning in 2026, indexed for inflation going forward. For married couples taking advantage of portability, that means up to $30 million can transfer estate-tax-free. Despite this generous threshold, high-net-worth families with business ownership stakes, real estate portfolios, and appreciating assets should not assume they are out of reach. Estate values can grow considerably between now and the date of death, and the gap between current assets and the exemption threshold narrows faster than most people expect.
Key Estate Tax Planning Strategies
Effective estate tax planning involves more than simply drafting documents. It requires a coordinated strategy that anticipates how your assets will grow, how ownership interests will transfer, and which legal tools will produce the best outcomes for your specific situation.
Some of the most commonly used estate tax planning instruments include:
- Irrevocable Life Insurance Trusts (ILITs): Removes life insurance proceeds from the taxable estate while providing liquidity to pay estate taxes or equalize distributions among heirs
- Grantor Retained Annuity Trusts (GRATs): Transfers appreciating assets to heirs at a reduced gift tax cost by retaining an annuity interest for a fixed term
- Qualified Personal Residence Trusts (QPRTs): Removes the value of a primary or secondary residence from the taxable estate while allowing the owner to continue living there during the trust term
- Charitable Remainder Trusts (CRTs): Provides an income stream to the grantor, a charitable deduction, and ultimately transfers remaining assets to charity outside the taxable estate
- Annual Exclusion Gifting: Transfers up to $19,000 per recipient per year free of gift tax, gradually reducing the taxable estate over time
Our attorneys evaluate each client’s full financial and ownership picture before recommending any combination of these tools, ensuring the plan reflects both the tax objectives and the broader goals of the family.
Estate Tax Planning for Business Owners
Business owners face a distinctive estate tax challenge. The value of a closely held company, an ownership interest in a partnership, or a stake in a real estate holding entity may represent the majority of the taxable estate, yet those interests are illiquid. Paying a 40 percent estate tax bill on an asset that cannot easily be converted to cash forces difficult decisions that can undermine the business itself.
Our attorneys have extensive experience working with clients involved in mergers and acquisitions and ownership transitions, which gives us a practical understanding of how business value is created, structured, and transferred. For clients whose estates include commercial real estate holdings, we bring additional depth in real property law that allows us to address those assets as part of an integrated plan. We also advise on the use of business organizations such as family limited partnerships and LLCs as estate planning vehicles, which can provide valuation discounts and facilitate the controlled transfer of ownership interests to the next generation.
Coordinating Gift and Estate Tax Planning
The federal gift tax and estate tax operate under a unified framework, which means gifts made during your lifetime reduce the exemption available at death. This interconnected structure requires careful coordination between lifetime giving strategies and estate plan documents to avoid unintended tax consequences.
Our attorneys work with clients to structure gifting programs that reduce the taxable estate over time while preserving sufficient liquidity for the client’s needs. For families with significant wealth across multiple generations, we also advise on generation-skipping transfer tax planning, which governs transfers to grandchildren and more remote descendants and carries its own set of rules and exemptions.
