Granting an income beneficiary a general power of appointment is just one way practitioners can err in drafting a see-through trust. There are no shortage of ways to make a mistake in this highly technical area. What if we determine after the death of the decedent that we do indeed have a faulty see-through trust? Presumably, we now have no choice but to distribute all IRA amounts not later than the end of year of the 5th anniversary of the decedent’s death. But what if, now that we’ve identified the problem, we simply amend the trust. For example, what if we amend the trust to provide that daughter’s power of appointment may only be granted in favor of any individual not older than daughter (as described in Part #3). Well, not so fast says the IRS. PLR 201021038 states clearly that the reformation of a trust instrument is not effective to change the tax consequences of a completed transaction. In short, an amendment to the trust document after the death of decedent to reform a defective see-through trust is unlikely to be permitted by the IRS. The lesson here is learn and understand the complex see-through trust rules before you draft the see-through trust document. Without proper drafting, practitioners face unhappy beneficiaries with IRA amounts distributed (and taxed) within five years of the decedent’s death (instead of over the lifetime of a designated beneficiary), with likely no remedy available.
