IRS Form 706-GS(T) Guide: GST Tax Return for Terminations

1. Introduction – What is Form 706-GS(T)?

IRS Form 706-GS(T), officially titled Generation-Skipping Transfer Tax Return for Terminations, is a specialized federal estate and trust tax return governed by the Internal Revenue Service (IRS). It is used to calculate, report, and pay Generation-Skipping Transfer (GST) tax when a taxable termination occurs within a trust.

Under Chapter 13 of the Internal Revenue Code, the GST tax applies to multi-generational transfers of wealth made to recipients who are two or more generations younger than the trust creator (grantor), known as skip persons (such as grandchildren or great-grandchildren).

A taxable termination occurs when an interest in trust property terminates (due to death, passage of time, or trust dissolution), leaving only skip persons as the remaining trust beneficiaries. Form 706-GS(T) is the official return used by trustees to settle GST tax liabilities arising from these termination events.

2. Purpose of the Form

The primary purpose of Form 706-GS(T) is to assess and collect federal GST tax at the trust level when a intermediate beneficiary’s interest ends. It ensures that family wealth transferred through long-term trusts is subjected to federal transfer taxes at each generational level.

Form 706-GS(T) solves the tax avoidance problem associated with generation-skipping trusts. For example, if a grandfather establishes a trust paying income to his child for life with the remaining assets passing to his grandchildren, no estate tax is assessed when the child dies. Form 706-GS(T) captures the transfer tax at the child’s death by treating it as a taxable termination.

Additionally, Form 706-GS(T) establishes trustee liability. Unlike trust distributions (where the beneficiary pays GST tax on Form 706-GS(D)), federal tax law holds the trustee personally liable for reporting and paying GST tax on taxable terminations out of trust property.

3. Who Needs to File This Form

Form 706-GS(T) must be filed by the trustee (or co-trustees) of any domestic or foreign trust that experiences a taxable termination during the calendar year.

A trustee must file Form 706-GS(T) if the following legal conditions are met:

• Taxable Termination Event: An interest in property held in trust terminates (e.g., upon the death of a primary life-income beneficiary).
• Only Skip Persons Remain: Immediately after the termination, no non-skip person holds an interest in the trust, or no future trust distributions can be made to a non-skip person.
• Non-Zero Inclusion Ratio: The trust has an inclusion ratio greater than zero (meaning the trust is not 100% exempt from GST tax).

4. Who Is Exempt / Not Required to File

Many trust terminations do not trigger GST tax, exempting trustees from filing Form 706-GS(T).

A trustee is NOT required to file Form 706-GS(T) in the following circumstances:

• Fully Exempt Trusts (Zero Inclusion Ratio): Trusts where the original grantor allocated sufficient lifetime GST exemption to achieve an inclusion ratio of zero (making all trust transactions completely tax-exempt).
• Non-Skip Person Retains Interest: Terminations where a non-skip person (such as another child of the grantor or a surviving spouse) retains or acquires an immediate interest in the trust property.
• Taxable Distributions: Interim payouts made to individual beneficiaries during ongoing trust operations (reported on Form 706-GS(D-1) and Form 706-GS(D) instead).
• Direct Skips: Outright transfers made directly to skip persons during life or at death (reported on Form 709 or Form 706).

5. When to File

Form 706-GS(T) is an annual tax return filed for any calendar year in which a taxable termination takes place.

Review the mandatory filing timeline rules:

• Standard Annual Due Date: Form 706-GS(T) must be filed on or after January 1, but no later than April 15 of the calendar year following the year in which the taxable termination occurred.
• Six-Month Extension: Trustees needing additional time to prepare the return can request an automatic 6-month extension by submitting Form 7004 on or before April 15.

6. Where and How to File

Form 706-GS(T) is a paper-based federal return submitted directly to the IRS. Electronic online e-filing is not available for this specialized return.

Mail the completed, signed Form 706-GS(T) along with payment for any GST tax owed to the designated IRS submission processing center address listed in the current official instructions for Form 706-GS(T) (typically the IRS Center in Kansas City, MO).

Make check or money order payments payable to the “United States Treasury”. Write the trust’s Employer Identification Number (EIN), tax year, and “Form 706-GS(T)” on the memo line of the check.

7. Step-by-Step Instructions to Fill the Form

Form 706-GS(T) contains a header identification block, Schedule A for property disclosures, and Part II for tax computation. Review the summary guide below.

Form Section	Section Title	Key Information to Disclose
Header & Part I	Trust & Transferor Identification	Trust legal name, EIN, trustee contact details, and original grantor/transferor legal name and SSN.
Schedule A (Cols a–d)	Terminated Property Values	Description of terminated trust property, termination date, valuation date, and gross Fair Market Value (FMV).
Schedule A (Line 5)	Allowable Deductions	Itemize trust administration expenses, trustee fees, and legal costs attributable to the termination.
Part II (Lines 1–6)	GST Tax Computation	Multiply net taxable termination amount by the trust’s applicable rate (inclusion ratio × top estate tax rate).
Signatures	Trustee Execution	Trustee signature and date affirming accuracy under penalties of perjury.

Header and Part I – Identification Information

Enter the trust’s legal name, EIN, physical mailing address, and the trustee’s phone number. In Part I, disclose the full legal name, Social Security Number (SSN), and date of establishment for the original grantor (transferor) who created and funded the trust.

Schedule A – Terminated Property and Allowable Deductions

On Schedule A, list all trust property items subject to the termination. State the exact termination date, valuation date, and gross Fair Market Value (FMV) as of the termination date. Crucially, subtract allowable deductions under Section 2622, such as trustee fees, legal accounting expenses, valuation appraisal costs, and unpaid trust debts directly connected to the terminated property.

Part II – GST Tax Computation

In Part II, combine the net taxable termination values from Schedule A and apply the trust’s inclusion ratio:

• Inclusion Ratio: Enter the trust’s inclusion ratio (calculated from prior Form 709 or Form 706 GST exemption allocation records).
• Applicable Rate: Multiply the highest federal estate tax rate in effect for the year (40%) by the inclusion ratio.
• Gross GST Tax: Multiply the net taxable termination value by the applicable rate.
• Net Tax Due: Subtract any allowable state GST tax credits to arrive at the net GST tax payable by the trust.

Signatures

The trustee (or authorized officer of an institutional trust company) must sign and date the return under penalties of perjury.

8. Required Documents/Information Needed Before Filling

Trustees must gather financial, appraisal, and historical tax records before completing Form 706-GS(T).

Ensure you have the following records ready:

• Trust Instrument & EIN: Certified copy of the trust agreement and assigned Employer Identification Number (EIN).
• Grantor GST Exemption History: Historical copies of Form 709 (Gift Tax Returns) or Form 706 (Estate Tax Returns) documenting GST exemption allocations made by the grantor.
• Professional Appraisals: Independent appraisal reports establishing date-of-termination Fair Market Values for real estate, business entities, or non-liquid assets.
• Termination Expense Records: Invoices and receipts for trustee fees, legal expenses, and accounting costs claimed as Schedule A deductions.

9. Common Mistakes to Avoid

Errors on Form 706-GS(T) can lead to severe fiduciary liability and audit adjustments. Avoid these common mistakes:

• Confusing Terminations with Distributions: Filing Form 706-GS(T) for interim distributions made to individual beneficiaries during ongoing trust administration (which require Form 706-GS(D-1) and Form 706-GS(D)).
• Failing to Claim Allowable Deductions: Forgetting to deduct trustee fees, legal administration costs, and appraisal expenses on Schedule A, resulting in overpaid GST taxes.
• Assuming Beneficiaries Pay the Tax: Believing the beneficiaries pay GST tax on a termination. The *trustee* is personally responsible for paying tax on Form 706-GS(T) from trust assets before distributing remaining funds.
• Miscalculating Inclusion Ratios: Miscalculating the trust’s inclusion ratio due to unverified historical GST exemption allocation records.
• Distributing Assets Before Paying Tax: Distributing all trust property to skip person beneficiaries before filing Form 706-GS(T) and paying the GST tax.

10. Penalties for Non-Filing or Errors

Failing to file Form 706-GS(T) or paying late carries severe administrative penalties and personal legal exposure for trustees.

Key risks and penalties include:

• Late Filing Penalty: Charged at 5% of unpaid GST tax per month, up to a maximum of 25%.
• Late Payment Penalty: Charged at 0.5% of unpaid GST tax per month, up to a maximum of 25%, plus mandatory compounding interest.
• Personal Trustee Liability (IRC Section 2603(a)(2)): The trustee is personally liable for paying the GST tax. If a trustee distributes trust assets to beneficiaries without paying Form 706-GS(T) tax, the IRS can collect unpaid taxes directly from the trustee’s personal assets.
