What Is Generation-Skipping Transfer (GST) Tax?
A federal tax imposed on transfers of wealth to beneficiaries who are two or more generations below the transferor, designed to prevent families from avoiding estate tax at each generation.
Understanding Generation-Skipping Transfer (GST) Tax
The generation-skipping transfer (GST) tax is a federal tax that applies when wealth is transferred to a "skip person," defined as someone who is two or more generations below the transferor (such as a grandchild or great-grandchild) or an unrelated person more than 37.5 years younger than the transferor. The GST tax was enacted to prevent wealthy families from avoiding the estate tax at each generational level by passing assets directly from grandparent to grandchild, thereby skipping the potential estate tax at the children's generation.
The GST tax is imposed at a flat rate equal to the highest federal estate tax rate (currently 40%) and applies on top of any applicable estate or gift tax. However, each individual has a GST tax exemption (approximately $13 million, indexed for inflation, matching the estate tax exemption). Proper allocation of the GST exemption is critical in multi-generational planning to avoid double taxation. When the exemption is fully allocated to a trust, the trust is said to have an "inclusion ratio" of zero, meaning all distributions and terminations are GST tax-free.
Life insurance is a powerful tool in GST planning. A dynasty ILIT funded with life insurance can leverage the GST exemption by using relatively small annual premium gifts to secure a large death benefit that is both estate-tax-free and GST-tax-free. This allows the death benefit to be held in trust for grandchildren and great-grandchildren without incurring additional transfer taxes at each generation, effectively multiplying the impact of the GST exemption.
Three types of taxable events trigger the GST tax: direct skips (outright transfers to skip persons), taxable terminations (when an interest in trust property terminates and skip persons become the only remaining beneficiaries), and taxable distributions (distributions from a trust to a skip person). Proper allocation of the GST exemption to trusts at the time of funding (or via late allocation procedures) is essential to ensure that future distributions and terminations remain GST-free. Estate planning attorneys and CPAs work together to track GST exemption allocation through gift tax returns and trust accounting records, while agents in our network ensure that life insurance policies funding GST-exempt trusts are properly structured and maintained over the long term.

Seeing Generation-Skipping Transfer (GST) Tax in Practice
Illustrative example: A 60-year-old Nashville couple with a $30 million estate creates a dynasty ILIT and allocates $4 million of their combined GST exemption to fund a $10 million survivorship whole life policy within the trust. The premiums, funded through annual exclusion gifts, leverage the $4 million GST allocation into a $10 million tax-free death benefit. Because the trust is GST-exempt, the $10 million can benefit their grandchildren, great-grandchildren, and beyond without incurring estate tax or GST tax at any generation. This example is illustrative only; actual tax results depend on current law, trust design, and individual circumstances. In a second illustrative scenario, a 75-year-old Knoxville grandmother makes a direct gift of $500,000 to her granddaughter to fund a college tuition trust. Because the granddaughter is a skip person (two generations below the grandmother), the gift is potentially subject to both gift tax and GST tax. By allocating $500,000 of her remaining GST exemption to the gift on her gift tax return, the transfer becomes GST-exempt. If she had not made this allocation, a 40% GST tax could have applied on top of any gift tax, significantly reducing the value reaching her granddaughter. Actual outcomes depend on current law and individual circumstances.
Generation-Skipping Transfer (GST) Tax in Tennessee
Tennessee is one of the premier jurisdictions for dynasty trusts used in GST planning. Tennessee's rule against perpetuities allows trusts to last up to 360 years, enabling GST-exempt trusts funded with life insurance to protect wealth across many generations. Tennessee has no state income tax on trust income from capital gains or interest (when properly structured), no estate tax, and no inheritance tax. These factors, combined with Tennessee's directed trust statutes and strong asset protection laws, make Tennessee a top choice for families nationwide seeking to establish GST-exempt dynasty trusts. In practice, agents in our network work with estate planning attorneys experienced in Tennessee dynasty trust planning to coordinate life insurance funding strategies. This includes selecting permanent life insurance products from A-rated (A.M. Best) carriers with strong long-term financial stability (since dynasty trust policies may be held for many decades), structuring premium funding to maximize annual exclusion gifts coordinated with GST exemption allocation, and ensuring policy ownership and trust beneficiary structures align with the GST-exempt design. Many Tennessee dynasty ILITs combine survivorship whole life policies with paid-up additions riders to maximize long-term cash value and death benefit growth, leveraging the GST exemption for generations of family wealth transfer. Guarantees are backed by the financial strength and claims-paying ability of the issuing insurance carrier.

Read Definition →Frequently Asked Questions About Generation-Skipping Transfer (GST) Tax
A skip person is an individual who is two or more generations below the transferor. For family members, this means grandchildren, great-grandchildren, and beyond. For non-family members, it is someone more than 37.5 years younger than the transferor. Trusts can also be skip persons if all beneficiaries are skip persons.
Life insurance in a GST-exempt dynasty trust leverages relatively small premium payments into a large, tax-free death benefit. By allocating GST exemption to the trust, the entire death benefit and its growth can benefit multiple generations without incurring estate tax or GST tax. This multiplies the impact of the exemption far beyond what could be achieved with other assets.
Tennessee allows trusts to last up to 360 years, has no state income tax, no estate tax, and no inheritance tax. Tennessee also offers directed trust statutes, trust decanting provisions, and strong asset protection. These factors make Tennessee one of the most favorable jurisdictions for dynasty trusts used in GST planning.
The three GST taxable events are: (1) Direct skips, which are outright transfers to skip persons; (2) Taxable terminations, which occur when an interest in trust property terminates and only skip persons remain as beneficiaries; and (3) Taxable distributions, which are distributions from a trust to a skip person. Each type has different mechanics for tax calculation and exemption allocation.
The GST exemption is allocated to trusts either automatically (through statutory rules for certain types of transfers) or by election on the donor's gift tax return (IRS Form 709). Proper allocation gives the trust an inclusion ratio of zero, meaning all future distributions and terminations are GST-free. Estate planning attorneys and CPAs work together to track allocations and ensure trusts maintain their GST-exempt status over time.
