IRS Form 706-GS(T)

Trusts are often used to transfer wealth to children, grandchildren, and future generations. While these arrangements can help families manage inheritances and preserve assets, certain trust events can trigger a specialized federal tax called the generation-skipping transfer tax, or GST tax.

IRS Form 706-GS(T), Generation-Skipping Transfer Tax Return for Terminations, is used by trustees to calculate and report GST tax due when a qualifying trust interest terminates. Understanding when this form applies can help trustees meet their federal filing obligations and avoid preventable tax complications. <Cite refs={[“turn163175search1″,”turn163175search0”]}/>

AIM Financial helps individuals and families understand tax preparation requirements and organize information for complex tax situations. This guide explains Form 706-GS(T) in plain English.

What Is IRS Form 706-GS(T)?

Form 706-GS(T) is a federal transfer-tax return used to report certain taxable terminations of interests in trusts.

A taxable termination generally occurs when someone’s interest in trust property ends and, as a result, the property can pass to a person or trust classified as a “skip person” for GST tax purposes.

A common example involves a grandparent who establishes a trust for a child, with the remaining assets passing to grandchildren after the child’s death. When the child’s interest ends, the trust may experience a taxable termination, depending on the trust’s terms and the applicable tax rules.

The form is different from an individual income tax return. It addresses transfer-tax consequences rather than simply reporting wages, interest, or other annual income.

Who Must File Form 706-GS(T)?

Generally, the trustee of a trust that has a taxable termination must file Form 706-GS(T) for the calendar year in which the termination occurs. The trustee is responsible for reviewing the trust arrangement, determining whether the event is taxable, calculating any applicable GST tax, and filing the return. <Cite refs={[“turn163175search0”]}/>

Situations that may require review include:

• A child’s interest in a family trust ends at death, allowing property to pass to grandchildren.
• A trust interest ends after a specified period, and the remaining property may be distributed to skip persons.
• A beneficiary’s interest ends because of the release of a power or another event described in the trust agreement.
• A trust holds assets for multiple generations and a termination changes who can receive the property.

Not every trust termination is taxable. For example, a termination generally does not qualify as taxable if a non-skip person has an interest in the property immediately afterward, or if no distribution can ever be made to a skip person after the termination. Special exceptions can also apply to certain older trusts and qualifying medical or educational payments.

The trust document and its tax history must be examined before deciding whether a return is required.

What Is a Skip Person?

A skip person is generally an individual who is two or more generations below the person who transferred the property. Grandchildren and more remote descendants are common examples.

Certain trusts can also be classified as skip persons under the GST tax rules.

The generation assignment is not always as simple as counting family relationships. Federal rules address adoption, spouses, unrelated individuals, and certain entities. In some circumstances, a person’s age relative to the transferor determines their generation for tax purposes.

This matters because the GST tax is intended to address certain transfers that bypass an intermediate generation. A trustee should not assume that a distribution to a grandchild is automatically taxable or that a transfer to another beneficiary is automatically exempt.

How Does the Generation-Skipping Transfer Tax Work?

The GST tax is a separate federal transfer tax that may apply in addition to estate or gift tax rules.

The amount of tax depends on several factors, including the value of the property involved in the termination, applicable deductions, the trust’s GST tax inclusion ratio, and any available exemption or credit.

The inclusion ratio is particularly important. In simplified terms, it helps determine the portion of a trust that is subject to GST tax. A trust with an inclusion ratio of zero is generally not subject to GST tax on the relevant transfer, while a positive ratio may mean that some or all of the termination is taxable.

Trustees may need records from the original gift tax or estate tax returns, including documentation of GST exemption allocations, to determine the correct treatment.

Because these calculations can be technical, trustees should avoid estimating the tax solely from the amount distributed.

When Is Form 706-GS(T) Due?

Form 706-GS(T) is generally due April 15 of the year following the calendar year in which the taxable termination occurs. If the due date falls on a Saturday, Sunday, or legal holiday, the deadline generally moves to the next business day. <Cite refs={[“turn163175search0”]}/>

For example, if a taxable termination occurs during 2026, the return would generally be due April 15, 2027.

If additional time is needed, the trustee may request an automatic extension by filing IRS Form 7004 on or before the original due date. Trustees should review the current instructions to understand payment requirements and avoid assuming an extension to file also extends the time to pay.

How Do You Complete Form 706-GS(T)?

The trustee should gather the trust agreement, distribution records, valuation information, and relevant tax documents before preparing the return.

The general process includes:

1. Identify the trust and trustee. Provide the requested identifying information, including the trust’s taxpayer identification number.
2. Describe the termination. Determine which interest ended and why the event occurred.
3. Review the trust’s tax history. Identify prior transfers, GST exemption allocations, and the applicable inclusion ratio.
4. Value the affected property. Use the valuation rules and dates required by the IRS instructions.
5. Calculate the taxable amount. Account for allowable deductions and expenses related to the trust or termination.
6. Calculate any GST tax due. Complete the applicable schedules and tax computation.
7. Sign and file the return. Follow the current IRS instructions and retain copies of supporting records.

Some trusts require separate schedules for different portions or beneficiaries. Additional care may be necessary when the trust received property from multiple transferors or has had additions over time.

Common Mistakes Trustees Should Avoid

Common errors include:

• Assuming every trust termination is taxable.
• Overlooking a termination because no cash was distributed immediately.
• Failing to review the trust’s GST tax inclusion ratio.
• Using incomplete or outdated trust records.
• Missing the April 15 filing deadline.
• Confusing GST tax with income tax reported by beneficiaries.
• Assuming an extension to file automatically extends payment time.

Keeping copies of the trust agreement, prior estate and gift tax returns, asset valuations, and trustee records can make compliance easier.
