Title 26 › Subtitle Subtitle B— - Estate and Gift Taxes › Chapter CHAPTER 13— - TAX ON GENERATION-SKIPPING TRANSFERS › Subchapter Subchapter D— - GST Exemption › § 2632
You can use your generation-skipping transfer (GST) exemption any time up to the deadline for filing your estate tax return (including extensions). The Secretary must provide the forms or rules for how to make the allocation. If you make a direct skip during your life, any of your unused GST exemption is automatically applied to that gift as much as needed so the gift won’t be subject to GST tax. If the gift is bigger than your unused exemption, all of the unused exemption is applied. You can choose in writing not to have this automatic rule apply. The same automatic rule applies to indirect skips (gifts to certain trusts called “GST trusts”), except that an indirect skip under section 2642(f) is treated as happening at the end of the estate tax inclusion period and its value is measured then. A “GST trust” is a trust that could produce a generation‑skipping transfer unless the trust document meets certain exceptions (for example, if more than 25 percent of the trust can go to non-skip persons before age 46, or if beneficiaries are more than 10 years younger, or certain charitable or estate‑inclusion trusts). You may elect not to have these rules apply to a transfer or to treat a trust as a GST trust. Those elections are generally made on a timely filed gift tax return for the year of the transfer (or by other dates the Secretary allows). If a non-skip person who is a lineal descendant of a grandparent of the transferor, assigned to a younger generation, and who had an interest in a trust dies before the transferor, an allocation filed on a gift tax return by the deadline in section 6075(b) for gifts in that year will be treated as if it had been made on time for each year the transfers occurred, will be effective just before that death, and will fix the transferor’s unused GST exemption immediately before that death. Any GST exemption not allocated by the filing deadline is treated as automatically allocated first to direct skips at death and then to trusts from which a taxable distribution or taxable termination might occur at or after death, with the allocation split among items in proportion to their nonexempt portions (value times inclusion ratio).
