Wealth often passes across several generations, but not every transfer is taxed the same way. Federal rules for generation-skipping transfers can affect gifts, inheritances, and trusts in ways that are easy to overlook. Knowing how these rules fit into broader transfer tax laws can help families evaluate their options before making significant wealth transfers.
Understanding the Generation-Skipping Transfer Tax
The generation-skipping transfer tax (GST tax) is a federal tax that may apply when assets are transferred to someone at least two generations younger than the transferor. It is separate from, but works alongside, the federal estate tax and gift tax.
Because of the lifetime exemption, the GST tax primarily affects larger estates. Even so, anyone considering multigenerational wealth transfers should understand when the rules apply.
Why the GST Tax Exists
Congress created the GST tax to prevent families from avoiding transfer taxes by skipping a generation. Without the GST tax, a grandparent could leave property directly to grandchildren instead of children, allowing assets to bypass one round of estate taxation.
How It Differs From Estate Tax and Gift Tax
Although they often work together, these taxes serve different purposes.
| Tax | Primary Purpose | During Life | At Death |
|---|---|---|---|
| Gift tax | Taxes certain lifetime transfers | ✓ | — |
| Federal estate tax | Taxes assets transferred at death | — | ✓ |
| Generation-skipping transfer tax | Taxes qualifying transfers to skip persons | ✓ | ✓ |
A single transfer may involve more than one federal transfer tax.1 For example, property transferred directly to a grandchild during life could be subject to gift tax rules while also qualifying as a generation-skipping transfer.
The GST tax does not replace estate or gift taxes. Instead, it operates alongside them when statutory requirements are met.
Types of Generation-Skipping Transfers
Federal law classifies generation-skipping transfers as direct skips, taxable distributions, and taxable terminations.2 Identifying the correct category determines who reports the transfer and when tax liability may arise.
Direct Skips
A direct skip occurs when property passes directly to a skip person. Common examples include:
- Lifetime gifts to grandchildren
- Property left directly to grandchildren through a will
- Certain transfers to qualifying trusts treated as skip persons
Direct skips are generally the simplest GST transactions because they involve an immediate transfer to a skip person.
Indirect Skips
Some generation-skipping transfers involve trusts rather than direct transfers to an individual. In these situations, GST tax consequences often depend on the trust's structure and when distributions are made to beneficiaries.
Taxable Distributions and Taxable Terminations
Not every GST event occurs when assets are first transferred to a trust.
- Taxable distribution: occurs when a trust distributes property to a skip person under circumstances defined by federal law.
- Taxable termination: occurs when all remaining non-skip interests in a trust end, leaving only skip persons with interests in the trust.
These distinctions matter because they determine who is responsible for reporting the transfer and whether GST tax may be due.
Who Pays the Generation-Skipping Transfer Tax?
The person responsible for paying the GST tax depends on how the transfer occurs. In some situations, the transferor pays the tax. In others, the recipient or trustee may be responsible for reporting and payment.
Responsibility varies because the Internal Revenue Code classifies generation-skipping transfers into several categories.
Who Qualifies as a Skip Person?
A skip person is an individual or, in some cases, a trust that meets the IRS definition for generation-skipping transfers. A skip person generally includes:
- A grandchild or later descendant.
- An unrelated individual more than 37½ years younger than the transferor.
- Certain trusts whose beneficiaries primarily consist of skip persons.2
A child whose parent dies before the transfer may be treated differently under the tax rules. In some situations, that grandchild moves into the parent's generation for GST tax purposes, reducing or eliminating GST tax exposure.
When the GST Tax Applies
The GST tax may apply when:
- Assets pass directly to grandchildren.
- Property is transferred to qualifying trusts benefiting future generations.
- Lifetime gifts are made to skip persons.
- Transfers occur at death through wills or trusts.
- Certain trust distributions skip an intervening generation.
Not every transfer to a grandchild results in GST tax. The availability of the lifetime exemption, annual gift tax exclusion rules, and other provisions may reduce or eliminate the tax.
How the Generation-Skipping Transfer Tax Works
The GST tax is one of the more technical federal transfer taxes because it often overlaps with gift and estate tax rules. Whether tax is due depends on the type of transfer, the value of the assets, and whether the transferor has remaining GST exemption available.
The GST Tax Rate
When the GST tax applies and no exemption is available, it is generally imposed at the highest federal estate tax rate in effect for the year of the transfer.
Because the rate can be significant, allocating the GST exemption appropriately may substantially reduce or eliminate tax on qualifying transfers. Federal tax laws can change over time, so current rates and exemption amounts should always be verified before making major transfers.
The Lifetime Exemption
Each individual has a lifetime GST exemption that can be applied to qualifying transfers during life or at death.2 The exemption is separate from the annual gift tax exclusion and tied to the federal estate and gift tax exemption.
For a married couple, each spouse has a separate GST exemption. The exemption amount is adjusted annually for inflation.
Relationship to Estate and Gift Taxes
The GST tax works alongside the federal estate tax and gift tax rather than replacing them. Depending on the transfer, more than one federal transfer tax may apply.
For example, a large lifetime gift to a grandchild may require gift tax reporting while also using part of the transferor's GST exemption. Likewise, assets transferred to a grandchild at death may be subject to both the federal estate tax and the GST tax if the applicable exemption has been exceeded.
For a direct skip, the transfer may be subject to both gift tax and the GST tax, depending on whether the transfer occurs during life and whether available exemptions apply.
Common Examples of Generation-Skipping Transfers
Generation-skipping transfers can occur in several ways, depending on how and when assets are transferred. Common examples include:
- A grandparent makes a lifetime gift directly to a grandchild.
- Assets are left to grandchildren through a will or revocable trust.
- Property is transferred to a dynasty trust for future generations.
- A trust distributes assets to a skip person under the terms of the trust.
Whether GST tax applies depends on the type of transfer, the value of the assets, and any available GST exemption.
Generation-Skipping Transfer Tax and Trusts
Trusts are frequently used in multigenerational wealth transfers by individuals and married couples because they can provide long-term management of assets while allowing distributions according to the grantor's wishes. Their tax treatment depends on the trust's structure and how GST exemption is allocated.
Dynasty Trusts
A dynasty trust is designed to hold assets for multiple generations while limiting repeated estate taxation. When properly structured and funded with available GST exemption, it may allow trust assets to appreciate outside future taxable estates, subject to federal and state law.
Because state laws vary on how long trusts can remain in effect, the design of a dynasty trust often depends on applicable state statutes.
Trust Income and GST Tax Considerations
Trust income does not automatically create GST tax liability. Instead, tax treatment depends on the type of trust, the beneficiaries receiving distributions, and whether those distributions qualify as taxable distributions under GST rules.
Reporting Generation-Skipping Transfers to the IRS
Several IRS forms may be required depending on the type of generation-skipping transfer and when it occurs. Whether the transfer is made during life, at death, or through a trust determines which form is generally used and who is responsible for filing.
- IRS Form 709: Used to report taxable lifetime gifts and certain GST transfers. It is also used to allocate GST exemption to qualifying transfers. Filing IRS Form 709 does not necessarily mean tax is owed, as many returns simply report transfers or document exemption allocations.
- IRS Form 706: Generally filed after death when a federal estate tax return is required. IRS Form 706 may also be used to allocate any remaining GST exemption to qualifying transfers occurring at death. Not every estate is required to file this return.
- Form 706-GS: Used to report certain GST tax events involving trusts, including taxable distributions and taxable terminations. Different versions of Form 706-GS apply depending on the type of transfer, making it important to identify the correct form before filing.
Estate Planning Strategies for Generation-Skipping Transfers
Families with significant estates often evaluate wealth transfer strategies when transferring assets across generations. The appropriate approach depends on family goals, asset types, anticipated future growth, and applicable tax law.
Using the Lifetime Exemption
Allocating the GST exemption strategically can reduce future transfer tax exposure. Because exemption allocations are often irrevocable, they should be made carefully and documented through the appropriate IRS filings.
Making Tax-Efficient Gifts
Lifetime gifting may reduce the size of a future taxable estate while transferring appreciating assets to younger generations. Common approaches include annual exclusion gifts, direct payment of qualified tuition or medical expenses, gifts of appreciating assets, and funding qualifying trusts. Each has different tax and reporting implications.
Working With Estate Planning Professionals
Generation-skipping transfers often involve multiple areas of estate planning, federal tax law, trust administration, and state law. Professional guidance may be appropriate when establishing trusts, allocating GST exemption, preparing IRS filings, or navigating complex multigenerational transfers.
Coordinating With Your Estate Plan
Generation-skipping transfers should be considered alongside the rest of an estate plan. Wills, revocable trusts and irrevocable trusts, and beneficiary designations can all affect how assets are transferred and whether GST tax rules apply.
Reviewing these documents together can help ensure available exemptions are used appropriately and that your wealth transfer goals remain aligned as circumstances or tax laws change.
Final Thoughts
The generation-skipping transfer tax may apply when assets are transferred to grandchildren, certain younger individuals, or qualifying trusts. Although relatively few families owe GST tax because of the available lifetime exemption, understanding the rules can help families structure gifts, trusts, and inheritances more effectively.
