FAQs About Trusts

Does Portability Make Bypass Trusts Obsolete?

by Rania Combs

Before this year, bypass trusts were necessary to preserve a deceased spouse’s federal estate tax exemption. This is no longer the case. Under the new estate tax rules, a deceased spouse’s estate tax exemption is portable.

But does this new law make bypass trusts obsolete? An excellent article by attorney and journalist, Deborah Jacobs, points out many instances when bypass trusts are beneficial despite portability.

Why Were Bypass Trusts Necessary?

When a person dies, he or she can pass all property to a surviving spouse without incurring any estate tax liability. This is called the “unlimited marital deduction.” So if Husband and Wife have a community estate worth $10 million, Husband can pass his half of the community estate to Wife tax free.

However, if those assets are transferred outright to the Wife, the community assets would now be under the her complete control. So when she dies, her estate would be worth $10 million. Without portability, Wife could pass up to the exemption amount tax free. But, her estate would be required to pay taxes on the excess.

How Do Bypass Trusts Work?

Bypass trusts work in the following way: Instead of passing all the estate to the surviving spouse, a portion of the estate up to the exemption amount is placed into a trust.

The trust assets can be used to provide the surviving spouse with income for the rest of his or her life. However, the assets placed in the trust would not be treated as being owned by the surviving spouse for tax purposes, and would therefore not be included in his or her estate for purposes of federal estate tax liability. Upon the surviving spouse’s death, the assets could be passed to the trust’s beneficiaries without estate tax.

The New Estate Tax Law

The new federal estate tax rules signed into law by President Obama on December 17, 2010 allows the executor of a deceased spouse’s estate to transfer a deceased spouse’s unused tax exemption to his or her surviving spouse for use in addition to the surviving spouse’s estate tax exemption. This makes it possible for a deceased spouse’s unused estate tax exemption to be stacked on top of the surviving spouse’s exemption without the use of a bypass trust.

Situations When Bypass Trusts Should Continue to be Used

Despite the fact that a deceased spouse’s exemption is now portable, Deborah Jacobs article, Planning for A Disappearing Estate Tax Break, suggests reasons why you may want to include a bypass trust in your planning. These include:

  1. Protecting the assets you leave from creditors. Assets that are left to your heirs in a trust rather than outright can be sheltered from disgruntled spouses, creditors and others who may sue your heirs.
  2. Remarriage of the surviving spouse. A surviving spouse who remarries may forfeit the deceased spouse’s unused exemption amount if the new spouse dies first. Additionally, the bypass trust allows you to control who gets the remaining assets upon the surviving spouse’s death. If you leave your assets outright to your surviving spouse, and he or she remarries and commingles those assets those of the new spouse, your children may not get the inheritance you would have intended.
  3. Your assets may appreciate. If your assets are left in trust, any appreciation on those assets will not be included in your surviving spouse’s estate. This reduces the possibility that your spouse’s estate will be worth more than the exemption amount when he or she dies.
  4. You have grandchildren (or might someday). Portability does not apply to the $5 million exemption from the generation skipping transfer tax. If you intend to include grandchildren as beneficiaries, you can make lifetime gifts to your grandchildren or apply part of your exemption to the bypass trust and include them as beneficiaries.
  5. Your plan already includes a bypass trust. There are many benefits of having a bypass trust, and you shouldn’t automatically change your will if it includes one. However, it is important that you review your will to ensure the amount of assets headed for the trust still reflects your intentions.
  6. Avoiding administrative pitfalls. An executor of a deceased spouse’s estate must transfer the unused estate tax exemption to the surviving spouse by filing an estate tax return within 9 months of death, even if no estate tax is due. If the executor fails to do so, the unused exemption is lost.
  7. The new estate tax law expires on December 31, 2012. If Congress does not pass new legislation before then, the exemption amount will be $1 million, the tax rate will increase to 55 percent, and portability may be a thing of the past.

Portability allows married couples to transfer up to $10 million to their heirs without the use of a bypass trust. But the use bypass trusts can still be beneficial in many situations, so it’s best to talk with your attorney about what is best for your individual circumstances.
