How Tax Exposure Impacts Estate Planning for High Net Worth Individuals in Austin

A $4 million home in Westlake, three years of vested Tesla RSUs, and a stake in a local software company can push a married couple well past the federal estate tax threshold faster than most realize. To manage tax exposure estate planning high net worth Austin families implement must account for rapidly appreciating local assets. While many families feared the scheduled Tax Cuts and Jobs Act exemption sunset would cut the per-person exemption in half, the passage of the federal One Big Beautiful Bill Act permanently increased the individual lifetime exemption to $15 million ($30 million for a married couple) starting January 1, 2026, redefining the tax exposure landscape for wealthy Austin households. Texas has no state estate or inheritance tax, which helps, but the 40% federal rate on amounts above the exemption means a poorly structured plan can still cost heirs millions of dollars. In this guide, attorney Kyle Robbins at Robbins Estate Law explains how to accurately assess this financial risk and which legal tools protect wealth before it transfers to the next generation.

Key Takeaways

• The federal estate tax exemption permanently increased under the One Big Beautiful Bill Act of 2025. Effective January 1, 2026, the individual exemption sits at $15 million ($30 million for married couples), providing highly favorable planning opportunities but still requiring coordination for rapidly growing estates.
• Texas has no state estate tax. The liability is entirely federal, but the 40% rate on taxable amounts is severe enough to demand serious attention from local families.
• Austin's asset mix creates compounding risk. Real estate valued by TCAD, tech equity, and private business interests can combine to push an estate well past the threshold without the owners realizing it.
• Texas community property provides a unique step-up advantage. At the first spouse's death, both halves of community property receive a stepped-up basis, a benefit common-law states do not offer.
• Advanced trusts must be funded before a claim or taxable event arises. Timing is not flexible, and a transfer made too late can be unwound under federal fraudulent transfer rules.

Why Tax Exposure Estate Planning High Net Worth Austin Families Require Is Complex

Austin's wealth concentration looks remarkably different from Houston or Dallas. The city's technology economy means a significant share of large estates hold unvested restricted stock units (RSUs), incentive stock options, and equity stakes in pre-exit startups. These specific assets can spike dramatically in value between the time a plan is drafted and the time a family actually needs it.

Real estate compounds this financial issue. Travis County Appraisal District (TCAD) valuations in neighborhoods like Westlake, Barton Creek, Tarrytown, and Circle C have climbed sharply over the past decade. A couple who bought a home in Westlake for $900,000 many years ago may now sit on an asset appraised above $4 million. They might not have updated their legal documents since the original purchase. That appreciation, combined with growing investment portfolios and private business interests, can push a combined estate well past the federal threshold without a single intentional wealth-building decision.

Unvested RSUs create an additional layer of complexity for tech executives. While IRC Section 83 dictates the income tax consequences of restricted property during life, the estate tax treatment of unvested equity depends on employer plan rules: if unvested RSUs are forfeited upon death, they escape the gross estate, but if the plan accelerates vesting or issues a payout to heirs, their fair market value is included in the gross estate under IRC Section 2033 or 2039 and taxed as Income in Respect of a Decedent (IRD) under IRC Section 691. Families who assume their RSUs are not really theirs yet are often surprised to learn the IRS treats them as taxable assets.

What the One Big Beautiful Bill Act of 2025 Changed

Before the One Big Beautiful Bill Act (OBBBA) was enacted, the federal lifetime exemption was slated to sunset at the end of 2025 and drop to roughly $7 million per person. Instead, the OBBBA permanently raised the exemption to $15 million per individual for 2026, indexed for inflation in subsequent years. For a married couple, utilizing portability allows a surviving spouse to capture the deceased spouse's unused exclusion (DSUE), establishing a massive combined shelter of $30 million. While this provides a wide safety margin, proactive planning remains vital for ultra high net worth estate planning Austin families experiencing rapid asset appreciation.

"The passage of the new tax laws changed the math entirely. Families who thought they would face massive exposure under the old sunset rules now have a highly favorable environment, but they must restructure to lock in those benefits before the next taxable event." — Kyle Robbins, Estate Planning Attorney

How Texas Community Property Affects Your Tax Exposure

Texas operates as a community property state under Texas Family Code Sections 3.001 through 3.003. This legal classification creates a distinct planning advantage that attorneys in common-law states cannot offer their clients. It provides a full double step-up in basis.

When one spouse dies, both halves of community property receive a stepped-up basis to fair market value at the date of death. In a common-law state, only the deceased spouse's half gets the step-up. For an Austin couple holding $4 million in appreciated stock as community property, the difference between a full step-up and a partial step-up can eliminate hundreds of thousands of dollars in embedded capital gains taxes.

This specific advantage matters heavily because it dictates which assets belong in a trust and which are better left as community property.

The Impact of IRS Revenue Ruling 2023-2

Moving an asset from community property into an irrevocable trust to reduce the taxable estate forfeits the step-up benefit for the surviving spouse's half. Recent IRS guidance emphasizes this exact cost. Under IRS Revenue Ruling 2023-2, assets held in an irrevocable grantor trust do not receive a stepped-up basis at the grantor's death if those assets are successfully excluded from the grantor's gross estate.

This rule creates a difficult choice for business owners. You cannot exclude highly appreciated assets from your taxable estate while simultaneously claiming a step-up in basis to eliminate capital gains tax. A well-structured plan carefully weighs the 40% estate tax rate against the applicable capital gains rate.

Texas law presumes that all property acquired during marriage belongs equally to both spouses. The burden falls on the party claiming separate property status to overcome that presumption. They must provide clear and convincing evidence, typically through detailed tracing documentation. For Austin professionals who received pre-marital stock units that continued to vest after the wedding, the classification question often becomes highly complex. Inherited assets commingled with joint brokerage accounts face similar challenges. Misclassification affects both estate calculations and the surviving spouse's basis step-up analysis.

If you are unsure how your assets are legally classified, speaking with an Austin estate planning attorney before the next taxable event is the right move. The estate planning attorney team at Robbins Estate Law regularly works through community property tracing for local tech and business-owner clients.

Core Tools for Tax Exposure Estate Planning High Net Worth Austin Portfolios Need

For estates projected to exceed the $15 million or $30 million federal threshold, a revocable living trust alone does not reduce taxes. Assets in a revocable trust remain in the gross estate for federal estate tax purposes. Meaningful reduction requires irrevocable structures funded during your lifetime.

The most frequently used tools for central Texas families include specific trust vehicles designed for different asset classes.

Spousal Lifetime Access Trusts (SLATs)

With a SLAT, one spouse transfers assets irrevocably to a trust that benefits the other spouse during life. The transferred assets leave the grantor's taxable estate while still providing indirect family access. SLATs carry a key risk regarding reciprocal structures. If both spouses create mirror SLATs and one is unwound, the IRS doctrine of reciprocal trusts may pull both back into the taxable estate.

Irrevocable Life Insurance Trusts (ILITs)

An ILIT owns a life insurance policy, keeping the death benefit entirely outside the taxable estate. The ILIT must be established before the policy is purchased. If you transfer an existing policy, you must survive three years under IRC Section 2035 to keep the benefit outside your estate. The trust uses annual exclusion gifts to pay the premiums. Beneficiaries receive a formal notice of their right to withdraw these funds, which satisfies IRS gift tax requirements.

Grantor Retained Annuity Trusts (GRATs)

GRATs provide excellent protection for startup founders. The grantor transfers assets into the trust and retains an annuity for a fixed term. The trust passes any appreciation above the IRS hurdle rate to heirs completely free of tax. GRATs work exceptionally well with volatile assets like pre-IPO equity. If a local tech company goes public, the massive growth transfers to the next generation without triggering additional gift taxes.

Qualified Personal Residence Trusts (QPRTs)

QPRTs tackle the local real estate boom directly. The grantor transfers a primary or secondary home into the trust at a reduced gift tax value. They retain the right to live there for a specific term of years. If the grantor outlives the term, the property passes to heirs outside the estate. A highly appreciated property in Barton Creek might only use a fraction of the lifetime exemption, depending on the current interest rates and the chosen term length.

Intentionally Defective Grantor Trusts (IDGTs)

An IDGT specifically separates income taxes and estate taxes. The trust structure ensures assets sit outside the estate for estate tax purposes but remain yours for income tax purposes. The grantor pays income tax on the trust earnings out of their own pocket. This allows the trust assets to grow tax-free, effectively transferring additional wealth to heirs without using more of your lifetime gift exemption.

It is critical to note that Texas does not permit self-settled asset protection trusts. House Bill 4058, introduced in the 2025 legislative session to permit them, failed to pass. Therefore, first-party spendthrift protections remain prohibited under Texas Property Code Section 112.035. Strategies involving Nevada or South Dakota trusts require specific cross-state structuring to hold up under Texas fraudulent transfer scrutiny.

"The right legal structure depends entirely on the asset mix. A GRAT makes sense for concentrated equity. A QPRT makes sense for high-value Austin real estate. There is no single answer that works for every family above the threshold." — Kyle Robbins, Estate Planning Attorney

Generation-Skipping Transfer Tax and Dynasty Trust Considerations

For families with significant wealth across multiple generations, the Generation-Skipping Transfer (GST) tax adds another layer of complexity. The GST tax applies at the same 40% federal rate on transfers to grandchildren and more remote descendants that bypass an intermediate generation. Each individual has a GST exemption that matches the base estate tax exemption amount.

A properly structured dynasty trust can hold assets across multiple generations while using the GST exemption to shelter them from this tax. While the Texas Constitution explicitly prohibits perpetuities (Tex. Const. art. I, § 26), Texas Property Code Section 112.036 provides substantial statutory runway by allowing trusts created on or after September 1, 2021, to last for up to 300 years. This 300-year window effectively permits the creation of multi-generational dynasty trusts, although real property assets cannot be restricted from sale for a period longer than 100 years.

The catch is strict administrative coordination. The GST exemption allocation must be made correctly on a timely filed gift tax return. Missed or incorrect allocations can expose future trust distributions to the 40% GST rate, erasing the primary planning benefit entirely.

Maximizing Portability and the DSUE

Portability allows a surviving spouse to capture the unused exemption of their deceased partner. This captured amount is called the Deceased Spousal Unused Exclusion (DSUE). With the OBBBA raising the individual limit to $15 million, preserving a partner's unused portion secures a combined $30 million shield. However, the IRS requires a formal election to lock this in. You must file an estate tax return (Form 706) even if the estate owes zero tax.

Under standard statutory rules, this return is due within nine months of death, plus a six-month extension. The IRS recently provided a simplified automatic extension under Revenue Procedure 2022-32. This rule permits up to five years from the date of death to elect portability, as long as the estate falls below the mandatory filing threshold. Families navigating these rigid deadlines should consult a probate and tax professional immediately after a loved one passes.
