What Is Generation Skipping Transfer Tax (GST Tax)?
The Generation Skipping Transfer Tax (GST Tax) is a federal tax levied on transfers of property, either outright or in trust, to beneficiaries who are two or more generations younger than the transferor. This includes individuals such as grandchildren, great-grandchildren, or unrelated persons who are more than 37.5 years younger than the donor131, 132, 133. The GST tax is part of the broader category of federal transfer taxes, falling under the umbrella of [Estate Planning and Taxation], and aims to prevent the avoidance of estate and gift taxes that would otherwise apply at each generational level129, 130. It applies in addition to any applicable gift tax or estate tax on the initial transfer127, 128.
The primary purpose of the generation skipping transfer tax is to ensure that wealth transferred across multiple generations does not escape taxation at each intervening generation. For instance, if a grandparent directly transfers assets to a grandchild, bypassing their child's generation, the GST tax steps in to impose a levy equivalent to what would have been paid had the assets passed through the child's estate125, 126. This tax affects significant [wealth transfer] strategies and requires careful consideration in comprehensive [estate planning].
History and Origin
The concept of taxing transfers that bypass generations emerged due to concerns that wealthy individuals could use instruments like [trusts] to transfer assets through multiple generations without incurring estate or gift taxes at each successive death124. Prior to the introduction of the generation skipping transfer tax, these types of arrangements allowed for perpetual tax avoidance, constrained only by common law rules like the rule against perpetuities123.
The first federal generation-skipping transfer tax was enacted by Congress in 1976 as part of efforts to unify the federal estate and [gift tax] system121, 122. This initial version attempted to impose a tax equal to the estate or gift tax that was avoided, effectively taxing the transfer as if it had passed through each skipped generation. However, this 1976 iteration proved administratively complex and was widely criticized120.
Consequently, in 1986, Congress repealed the original GST tax and replaced it with the current version119. The Tax Reform Act of 1986 implemented a simpler, flat-rate tax on generation-skipping transfers, generally set at the highest federal estate tax rate118. This reform solidified the GST tax as a permanent component of the U.S. transfer tax system, designed to prevent an "end run" around the traditional estate and gift taxes117.
Key Takeaways
- The Generation Skipping Transfer Tax (GST Tax) applies to transfers of property to individuals two or more generations younger than the transferor, known as "skip persons."115, 116
- It is an additional federal tax imposed to ensure that wealth transferred across multiple generations does not avoid gift or estate taxes at each intervening generational level113, 114.
- The GST tax has a flat rate, which is currently set at the highest federal estate tax rate112.
- Each individual has a lifetime GST [exemption amount] that can be allocated to transfers to reduce or eliminate the tax111.
- The tax applies to direct skips, taxable distributions from trusts, and taxable terminations of trusts involving skip persons110.
Formula and Calculation
The Generation Skipping Transfer Tax is calculated by applying a flat rate to the non-exempt portion of a generation-skipping transfer. This rate is equal to the highest federal estate and gift tax rate in effect at the time of the transfer, which has been 40% since 2014109.
The calculation involves determining the "inclusion ratio" for the transfer or trust. The inclusion ratio is the portion of the transfer or trust that will be subject to the GST tax after considering the allocated GST exemption.
The formula for the inclusion ratio is:
Once the inclusion ratio is determined, the actual tax rate applied to the generation-skipping transfer is:
For example, if the maximum federal estate tax rate is 40%, and a transfer has an inclusion ratio of 0.5 (meaning half is exempt), the effective GST tax rate on the entire transfer would be (40% \times 0.5 = 20%). If the entire transfer is subject to GST tax (inclusion ratio of 1), the rate would be 40%108. The value of the [taxable estate] or gift, after accounting for the allocated exemption, is what the tax is applied to107.
Interpreting the Generation Skipping Transfer Tax
Understanding the Generation Skipping Transfer Tax is crucial for individuals engaged in significant [wealth transfer] to younger generations. The tax effectively imposes an additional layer of taxation on transfers that bypass the transferor's immediate descendants, preventing what was historically a loophole in the federal transfer tax system105, 106.
Interpretation of the GST tax often revolves around identifying "skip persons" and the types of transfers that trigger the tax. A "skip person" is generally someone two or more generations below the transferor, such as a grandchild, or an unrelated individual who is more than 37.5 years younger104. Transfers can occur as "direct skips" (outright gifts or bequests to a skip person), "taxable distributions" (distributions from a [trust] to a skip person), or "taxable terminations" (the end of an interest in a trust where property then passes to a skip person)103.
Effective interpretation and planning involve strategically allocating the GST [exemption amount] to minimize or eliminate the tax. Given that the GST tax can be applied on top of gift or estate taxes, the cumulative effect of these taxes, along with potential state-level taxes, can significantly reduce the amount of wealth that ultimately reaches future generations102.
Hypothetical Example
Consider a scenario where an individual, Ms. Eleanor Vance, wishes to leave a substantial inheritance to her granddaughter, Sarah, while Sarah's parent (Ms. Vance's child) is still alive. Ms. Vance has already utilized her lifetime gift and estate tax exemption with other transfers.
Suppose Ms. Vance transfers $5 million directly to a trust for the sole benefit of Sarah upon her death. The current GST tax exemption is $13.99 million for 2025101. However, Ms. Vance has already used her entire unified credit and GST exemption with prior gifts and bequests. Therefore, this $5 million transfer to Sarah is fully subject to the generation skipping transfer tax.
Here's how the tax would apply:
- Identify the Transfer Type: This is a "direct skip" because the assets are transferred directly to a "skip person" (Sarah, who is two generations younger)100.
- Determine the Taxable Amount: Since Ms. Vance has no available GST exemption to allocate to this transfer, the entire $5 million is considered a taxable generation-skipping transfer.
- Apply the Tax Rate: The generation skipping transfer tax rate is currently a flat 40%.
Calculation:
GST Tax = Taxable Amount × GST Tax Rate
GST Tax = $5,000,000 × 0.40
GST Tax = $2,000,000
In this hypothetical example, the trust established for Sarah would incur a $2,000,000 generation skipping transfer tax liability. This illustrates the significant impact of the GST tax on wealth transfers designed to bypass intermediate generations, underscoring the importance of careful [estate planning] and proper allocation of the [exemption amount].
Practical Applications
The Generation Skipping Transfer Tax significantly impacts various aspects of financial planning, particularly in the realm of [wealth transfer] and [estate planning]. One key application is in structuring multi-generational [trusts], such as "dynasty trusts". 99These trusts are designed to hold assets for many generations, potentially avoiding estate taxes for extended periods. The strategic allocation of the GST [exemption amount] to these trusts can shield substantial assets from the GST tax, allowing them to grow tax-free for the benefit of future [beneficiaries].
98
Another practical application arises in direct bequests or gifts to grandchildren or other skip persons. 97Without proper planning and utilization of the GST exemption, these direct transfers can trigger the GST tax in addition to any gift or estate tax. 96For example, families engaging in significant charitable giving alongside intergenerational transfers must also consider how the GST tax interacts with their overall financial and philanthropic goals.
The IRS provides specific guidance and forms for reporting generation-skipping transfers, including Form 709 (for lifetime gifts), Form 706-GS(D-1) and 706-GS(D) for distributions, and Form 706-GS(T) for taxable terminations. 94, 95Understanding these forms and the reporting requirements is critical for compliance. For more detailed official information, the Internal Revenue Service offers comprehensive guidance through resources like Publication 559, "Survivors, Executors, and Administrators".

Limitations and Criticisms
While designed to prevent tax avoidance, the Generation Skipping Transfer Tax can be complex to navigate, leading to potential pitfalls for those unfamiliar with its intricacies. One common criticism centers on its complexity and the detailed record-keeping required for tracking the allocation of the GST [exemption amount] to various trusts and transfers. 91Missteps in allocation can result in unintended tax liabilities.
90
Another limitation is its potential for creating significant tax burdens on large multi-generational transfers, sometimes in conjunction with [estate tax] and state inheritance taxes, which can collectively diminish family wealth for successive generations. 89While the goal is to tax transfers as if they passed through each generation, the flat rate of the GST tax, often at 40%, can be substantial.
88
Historically, the GST tax has faced criticism due to its impact on philanthropic endeavors and the efficient transfer of family businesses. 87Legislative changes, such as the temporary doubling of the exemption amounts under the Tax Cuts and Jobs Act (TCJA), have altered its practical application and reduced the number of estates subject to it. 85, 86However, the sunset provisions of these acts mean that planning must anticipate potential future changes in exemption levels and tax rates. 84The effectiveness of the GST tax in achieving its policy goals continues to be a subject of discussion among tax policy experts.

Generation Skipping Transfer Tax vs. Estate Tax
The Generation Skipping Transfer Tax (GST Tax) and the [Estate Tax] are both federal transfer taxes, but they serve distinct purposes within the overall taxation framework for wealth. The estate tax is levied on the total value of an individual's assets transferred at death, after accounting for deductions and an applicable [exemption amount]. 81, 82It is a tax on the privilege of transferring property from a decedent to their heirs.
In contrast, the GST tax is an additional tax designed to catch transfers that "skip" a generation, thereby avoiding the estate or gift tax that would normally apply to that intermediate generation. 79, 80For example, if a grandparent leaves assets to a child, that transfer is typically subject to estate tax (if above the exemption). If that child then leaves the remaining assets to their own child (the grandchild), another estate tax event occurs. However, if the grandparent leaves assets directly to the grandchild, bypassing the child's generation entirely, the GST tax is triggered to ensure a tax is paid at the skipped generational level, in addition to any applicable estate tax on the grandparent's original transfer. 78While both taxes aim to tax wealth transfers, the GST tax specifically targets transfers that would otherwise avoid a layer of taxation at an intervening generation.
FAQs
1. Who pays the Generation Skipping Transfer Tax?
The responsibility for paying the Generation Skipping Transfer Tax depends on the type of transfer. For a "direct skip" (an outright gift or bequest to a skip person), the transferor (or their estate) is generally responsible for the tax. 77For "taxable distributions" from a [trust] to a skip person, the beneficiary receiving the distribution typically pays the tax. For "taxable terminations" of a trust, the trustee is usually responsible.
2. What is a "skip person"?
A "skip person" is an individual who is two or more generations younger than the person making the transfer. 75, 76Common examples include grandchildren or great-grandchildren. An unrelated person can also be a skip person if they are more than 37.5 years younger than the transferor.
74
3. Is there an exemption for the Generation Skipping Transfer Tax?
Yes, each individual has a lifetime GST [exemption amount] that can be allocated to transfers to reduce or eliminate the tax. 73This exemption is typically unified with the lifetime gift and [estate tax] exemption and is adjusted annually for inflation. 71, 72There is also an annual gift tax [annual exclusion] that can be used for transfers to skip persons without incurring GST tax or using up the lifetime exemption.
70
4. Does the GST tax apply to all gifts to younger generations?
The GST tax only applies to gifts or bequests made to "skip persons". 69Transfers to your children, for example, would not typically trigger the GST tax, although they might be subject to gift or estate tax if they exceed the applicable [exemption amount] or annual exclusions.
68
5. Can the Generation Skipping Transfer Tax be avoided?
The GST tax cannot be entirely "avoided" if the transfer is to a "skip person" and exceeds the available exemptions. However, it can be minimized or eliminated through careful [estate planning] strategies, primarily by strategically allocating the lifetime GST [exemption amount] to transfers that would otherwise be subject to the tax. Creating and funding "dynasty trusts" with allocated GST exemption is a common technique to allow assets to pass through many generations free of subsequent transfer taxes.[66, 671](https://www.law.cornell.edu/wex/generation-skipping_transfer_tax), 234[5](https:/63, 64, 65/turbotax.intuit.com/tax-tips/family/what-is-the-generation-skipping-tax/L5mfqiA5z)6, [61, 627](https://www.congress.gov/crs-product/R48183)[8](https://www.americanbar.org/groups[59](https://www.congress.gov/crs-product/IF13053), 60/real_property_trust_estate/resources/probate-property/2025-january-february/generation-skipping-transfer-tax-opportunities/)910, 1112[13](https://www.congress.gov/crs-product/IF130[57](https://taxpolicycenter.org/briefing-book/how-do-estate-gift-and-generation-skipping-transfer-taxes-work), 5853)14, 1516, 1718, 195520[21](https://www.americanbar.org/groups/real_property_trust_estate/res[53](https://taxpolicycenter.org/briefing-book/how-do-estate-gift-and-generation-skipping-transfer-taxes-work), 54ources/probate-property/2025-january-february/generation-skipping-transfer-tax-opportunities/)222324, 2526, 272829[30](https://www.americanbar.org/groups/real_property_trust_estate/resources/probate-property/2025-january-februa[47](https://www.irs.gov/pub/irs-pdf/p559.pdf), 48ry/generation-skipping-transfer-tax-opportunities/)3132[33](htt45, 46ps://www.congress.gov/crs-product/IF13053)34353637, 383940
