# Generation-Skipping Transfer Tax: Planning Around the Exemption

## Quick answer

The 2026 GST exemption is $15 million per individual, providing a tool to shield multi-generational transfers from a 40% federal tax. Success requires proactive allocation on Form 709 to establish a zero inclusion ratio. Because future appreciation stays inside the exempt portion, early allocation to high-growth assets is often a priority for high-net-worth Oklahoma families.

## Key takeaways

- For the 2026 tax year, each individual has a $15 million federal generation-skipping transfer (GST) tax exemption.
- The GST tax is assessed at the maximum federal estate-tax rate, which is currently 40%, multiplied by the trust's inclusion ratio.
- Unlike the gift and estate tax exclusion, the GST tax exemption is not portable and cannot be transferred to a surviving spouse via portability elections.
- The 2026 annual gift-tax exclusion of $19,000 per recipient only applies to GST tax if the transfer is a direct skip or meets narrow trust-specific requirements.
- Automatic allocation rules act as a safety net but may inadvertently consume exemption on trusts intended primarily for children rather than grandchildren.

The generation-skipping transfer tax is easy to misunderstand because it usually does not announce itself when the plan is created. A family can fund a trust today, file a gift tax return, and see no immediate GST tax. The problem may surface decades later—when a child dies, a grandchild receives a distribution, or the trust terminates—and by then the original allocation decision may be difficult or expensive to repair.

For 2026, each individual has a $15 million federal GST exemption. The annual gift-tax exclusion is $19,000 per recipient. 1 Those are generous amounts, but they do not make the GST system automatic or forgiving. The exemption protects a transfer only when it is properly allocated. The planning decision is therefore not simply how much to give. It is which transfers should receive GST exemption, how the allocation will be reported, and whether the family's legal documents and long-term objectives support that choice.

## What The Tax Is Trying To Do

The federal estate and gift tax system generally imposes transfer tax as wealth moves from one generation to the next. Without a separate rule, a family could try to bypass the children's generation and move assets directly to grandchildren or hold them in trust until the children's interests end. The GST tax is the backstop. It applies to three categories of events: a direct skip, a taxable distribution, and a taxable termination. 2

A direct skip is generally a transfer subject to gift or estate tax that goes directly to a skip person. A grandchild is the familiar example, although generation assignment rules and the predeceased-parent exception can change the result. A taxable distribution generally occurs when a trust distributes to a skip person and the event is not already a direct skip or taxable termination. A taxable termination generally occurs when the interests of non-skip beneficiaries end and only skip beneficiaries remain. 2

The person responsible for the tax depends on the event. The transferor generally bears the tax on a direct skip, the recipient generally bears it on a taxable distribution, and the trustee generally bears it on a taxable termination. 2 That difference matters when documents assign tax burdens, trustees plan liquidity, and families evaluate who ultimately receives the economic benefit.

## The Exemption Works Through Allocation

The 2026 GST exemption is $15 million per person. A married couple may therefore have as much as $30 million of combined planning capacity if each spouse owns or transfers the relevant property and each spouse's exemption is allocated correctly. It is not a shared marital bucket. Unlike the estate and gift tax basic exclusion, a deceased spouse's unused GST exemption is not portable to the survivor. 1,6 An unused exemption can disappear at death if the estate plan and return do not direct an effective allocation.

The exemption is allocated to a transfer or to a trust. That allocation determines an inclusion ratio between zero and one. At a high level, an inclusion ratio of zero means the transferred property is fully GST exempt; an inclusion ratio of one means it is fully exposed; and a ratio between zero and one means it is partially exposed. The applicable GST rate equals the maximum federal estate-tax rate multiplied by the inclusion ratio. With a 40% maximum rate, an inclusion ratio of 0.50 produces a 20% applicable rate. 4

Figure 1 shows the mechanics using a $10 million hypothetical GST taxable event. With no exemption allocated, the inclusion ratio is 1.0 and the illustrative tax is $4 million. Allocating $5 million at the time of a $10 million transfer produces a simplified 0.50 inclusion ratio and $2 million of illustrative tax. Allocating $10 million produces a zero inclusion ratio and no GST tax on that event. The calculation ignores valuation adjustments, deductions, later additions, and special rules; it is designed to make the allocation relationship visible, not to estimate a particular family's return.

The economic advantage of an early, correct allocation is that future appreciation can remain inside the exempt portion. A late allocation may still be available, but it is generally measured using the trust's value when the late allocation becomes effective. If the assets have appreciated, more exemption may be required to reach a zero inclusion ratio. 5 This is why high-growth assets often deserve priority when exemption is limited—but asset selection must also account for liquidity, concentration, income tax, and basis.

## Automatic Allocation Helps, But It Does Not Plan For You

Federal law automatically allocates unused GST exemption to many lifetime direct skips and to certain indirect skips made to a “GST trust,” generally to the extent needed to produce a zero inclusion ratio. A donor can elect out, and in some circumstances can elect to treat a trust as a GST trust or make a different allocation. 3,5

This safety net prevents some accidental failures, but it can also consume exemption where the donor did not intend. A trust may technically satisfy the statutory GST-trust definition even if the family expects children—not grandchildren—to receive most of its value. Conversely, a trust the family informally calls a “generation-skipping trust” may fall within an exception to the automatic-allocation definition. The trust agreement, beneficiary ages, withdrawal rights, distribution standards, powers of appointment, and expected use of the assets all matter.

Our preference is to make the decision explicit. For each transfer, the attorney and CPA should identify the transferor, the trust, the value, the intended inclusion ratio, the amount of exemption allocated, and any election in or out of the automatic rules. Form 709 should document that decision even when no gift tax is due. A future trustee should be able to trace the trust's inclusion ratio without reconstructing decades of assumptions.

There is another timing trap when an estate tax inclusion period, or ETIP, applies. Certain retained interests can delay the effective allocation until the ETIP closes. 5 A transferor should not assume that exemption assigned on the date of funding immediately shelters the trust if the transferor retained an interest or power that triggers those rules.

## The Annual Exclusion Is Narrower Than It Looks

The 2026 annual gift-tax exclusion is $19,000 per recipient, and spouses may each use an exclusion when the ownership and gift-splitting requirements are satisfied. 1,5 But an annual-exclusion gift is not automatically exempt from GST tax merely because it is below $19,000.

A direct gift of a present interest to a grandchild can qualify for the gift and GST annual exclusions. A transfer to a trust has a narrower GST rule. In general, the trust must have only one beneficiary who is a skip person during that beneficiary's life, and the trust property must be includible in that beneficiary's estate if the beneficiary dies before the trust ends. 5 Many long-term family trusts do not meet that test. Withdrawal rights may create a present-interest gift for gift-tax purposes while the transfer still requires a separate GST allocation.

Direct payments of qualifying tuition to an educational institution or qualifying medical expenses to the provider are different. Properly structured payments excluded under Section 2503(e) are also excluded from the definition of a generation-skipping transfer. 2,5 The payment must go directly to the school or provider; reimbursing a family member is not the same result.

## Where The Exemption Usually Adds The Most Value

GST exemption is most valuable when a family intends capital to remain in trust for grandchildren and later descendants, the assets have a long time horizon, and the estate is large enough that repeated transfer taxes are a realistic concern. A properly designed trust can combine transfer-tax planning with creditor protection, professional investment management, and distribution governance.

When exemption is scarce, I would normally compare assets by expected appreciation, cash-flow needs, valuation certainty, basis, and the likelihood that the family will retain the asset. A private business interest with substantial upside may be a stronger candidate than a low-growth asset. Yet the plan should remain tax-aware, not tax-driven. Moving a volatile or illiquid asset to a trust can create funding, appraisal, and trustee problems that outweigh the theoretical GST benefit.

The distinction between gift and GST exemption also matters. The amounts happen to be equal in 2026, but they are separate systems. A donor can use gift-tax exemption without making the transfer GST exempt. A donor can also allocate GST exemption to an existing trust in some circumstances without making a new gift. The returns and allocation schedules—not the similarity of the headline amounts—determine the result. 1,3,5

## When It May Be The Wrong Tool

A multi-generational exempt trust is not automatically appropriate for every family with grandchildren. It may be a poor fit when the donor needs the assets for lifetime spending, the estate is unlikely to face federal transfer tax, the family wants children to own and control the property outright, or the expected benefit is too small to justify legal, tax, appraisal, and trustee costs.

Income-tax basis deserves particular attention. Property transferred by gift generally carries the donor's basis, while property included in a decedent's estate generally receives a basis tied to fair market value at death, subject to exceptions. 7 Removing a low-basis asset and its appreciation from an estate may reduce transfer-tax exposure but sacrifice a potential basis adjustment. The right answer depends on expected estate tax, expected capital gain, holding period, state law, and whether the asset is likely to be sold.

Partial exemption can also create complexity. A trust with an inclusion ratio between zero and one requires careful tracking, and later additions may change the calculation. In some cases, counsel may recommend separate exempt and nonexempt shares or a qualified severance. 4 That is a legal and tax design decision, not an investment-account labeling exercise.

## A Practical Review Process

The first step is to inventory every trust that could benefit a skip person. For each trust, locate the governing document, all Forms 709 and 706, notices of allocation, prior elections, appraisal reports, and trustee records. If the inclusion ratio cannot be supported, that is a planning issue now—not merely a recordkeeping issue for the future.

Next, project how the trust is likely to be used. Who may receive distributions? When could a child's interest terminate? Are additional gifts planned? Which assets are expected to appreciate? Does the donor need access or cash flow? A trust designed for children with only a remote possibility of passing to grandchildren may deserve a different allocation decision from a trust intended to hold family capital for several generations.

Then coordinate the reporting before the return is filed. The estate attorney should confirm the trust's tax design and state-law terms. The CPA should prepare the Form 709 allocation, election statement, and valuation disclosures. Our team can model how different assets and funding amounts affect liquidity, concentration, and the family's long-term balance sheet. The trustee should retain the final documents as part of the permanent tax record.

Finally, review the plan after major events: a new contribution, marriage or divorce, beneficiary death, trust modification, business sale, change of trustee, large distribution, or change in federal or state law. GST planning has a long horizon. The documentation needs to last just as long.

## Closing

The GST exemption is valuable because it can protect more than the amount originally transferred. A correct allocation can shelter decades of future appreciation. A missed, late, or unintended allocation can waste exemption or leave a trust exposed when the family believed it was protected.

The takeaway is straightforward: decide which transfers are truly meant for multiple generations, allocate exemption intentionally, and preserve the evidence. The legal document, tax return, investment plan, and family purpose should all tell the same story.

## Frequently asked questions

### Is the GST exemption portable to a surviving spouse?

No, unlike the basic exclusion for estate and gift taxes, a deceased spouse's unused GST tax exemption is not portable and will disappear if not effectively allocated by the estate.

### How does the GST inclusion ratio affect tax liability?

The inclusion ratio determines the portion of a trust exposed to tax; a ratio of zero signifies a fully exempt trust, while a ratio of one means the transfer is fully taxable at the maximum federal rate.

### What is the 2026 annual gift-tax exclusion for GST purposes?

For 2026, the annual exclusion is $19,000 per recipient, though transfers to trusts must meet specific criteria, such as having a single skip-person beneficiary, to qualify for the GST annual exclusion.
