You’ve undoubtedly seen the headlines about the end of the generous federal estate and gift tax exemptions coming at the end of 2025. Nevertheless, most Americans don’t have estates worth $13,610,000 or $27 million for couples. A recent article, “Is there a tax trap in your trust?” from Los Angeles Daily News, says we should be more concerned with an income tax issue for trusts, especially if they were created years ago.
Trusts created before 2010 commonly contained a trust provision to divide the trust in two upon the death of the first spouse. There were two reasons to split the trust. One was to be sure the surviving spouse didn’t change the named beneficiaries and leave the assets in the trust to someone else, like a new spouse.
The second reason was so each spouse’s estate tax exemption could be used. The use of both spouses’ exemptions mattered more way back then because the exemption was far lower than today: $1 million in 2002.
After 2010, if a married couple had a trust worth $5 million and their trust left everything to each other, the surviving spouse could inherit the trust and then change beneficiaries, disinheriting any offspring from a prior marriage. Even if they didn’t do this, when the second spouse died, there would be an estate tax on the estate's value over the second spouse’s tax exemption.
The A/B Trust solved the problem. The “B” part of the trust was an irrevocable trust and owned the deceased spouse’s share of assets and used the decedent spouse’s estate tax exemption. In 2010, the Tax Relief, Unemployment Reauthorization and Job Creation Act of 2010 became law, and the portability of the estate tax exemption for the first spouse to die was established. The surviving spouse had the option to file an election to preserve the deceased spouse’s estate tax exemption to be applied upon their own death.
The Tax Cuts and Jobs Act came along and raised the estate tax exemption from $5,490,000 to $11,180,000 in 2018. With increases for inflation, most married couples today don’t concern themselves with both spouse’s exemption amounts. However, a new issue must be considered and discussed with your estate planning attorney, especially if you live in a community property state.
When the first spouse dies, all the jointly owned assets receive a step-up in income tax basis in community property states (but only a step-up on the half attributed to the decedent spouse in separate property states). If you purchased an asset for $100, your basis is $100. If you sold it for $1,000, you’d have a profit or gain of $900. However, if the stock was worth $1,000 when the first spouse died, the new basis is $1,000 in a community property state. The beneficiary can sell the stock for $1,000 with no gain. When the second spouse dies, there’s another step-up on income tax basis. However, assets in a “B” trust—those of the first spouse to die—don’t receive another step-up in basis.
The result could be a significant capital gain when the assets are sold, especially if a lot of time has passed since the first spouse's death. If your trust hasn’t been reviewed or revised in a long time, you may want to update your trust, so the share of the first spouse to die goes instead into a marital trust.
A marital trust is drafted to protect contingent beneficiaries, typically the children from the marriage with the first spouse. It also serves to include assets in the surviving spouse’s estate, so the assets get that second step-up in basis.
This is an example of how changes in tax laws require trusts and estate plans to be reviewed by estate planning attorneys. Tax laws change, and personal situations do, too. You may have had a great plan when it was created. However, if your estate plan hasn’t been reviewed or updated in a while, it’s time to make an appointment with an experienced estate planning attorney.
