How Does The 2026 Obbba 15 Million Exemption Impact Portable Dsue For Surviving Spouses?
Proper estate planning isn’t simply about having a will; it’s about having a comprehensive estate planning strategy tailored to your specific circumstances and the ever-changing tax landscape. An experienced wills attorney can analyze statutory validity and ensure your estate plan is structured to minimize potential tax exposure. The complexities of the federal estate tax, particularly the rules surrounding portability, require careful consideration. For example, the ability to utilize a surviving spouse’s unused exemption—known as “DSUE”—is a critical component of many estate plans, but it must be properly elected. A CPA-attorney integrating tax considerations into wills can provide a significant advantage in these situations.
The One Big Beautiful Bill Act (OBBBA), enacted in 2023, fundamentally altered the trajectory of federal estate tax law. As of January 1, 2026, the federal estate tax exemption is permanently fixed at $15 million per person ($30 million for married couples) with annual inflation adjustments. This change has significant implications for estate planning, particularly for couples with estates approaching or exceeding this threshold. The ability to utilize the portability of the deceased spouse’s exemption is crucial for maximizing tax benefits, and requires careful planning and execution.
What is the federal estate tax exemption, and how does it work?

The federal estate tax is a tax on the transfer of wealth at death. However, it only applies to estates exceeding a certain threshold—the federal estate tax exemption. Prior to 2017, the exemption was significantly lower, but the Tax Cuts and Jobs Act temporarily increased it to $12.92 million per individual (adjusted annually for inflation). The OBBBA effectively eliminates this temporary increase, reverting the exemption to $15 million (adjusted for inflation) as of January 1, 2026. This means that estates exceeding $15 million will be subject to federal estate tax, while those below that amount will not.
The exemption is “portable,” meaning that a surviving spouse can utilize any unused portion of the deceased spouse’s exemption to increase their own exemption. This is particularly beneficial for couples where one spouse has a smaller estate. To elect portability, the executor of the deceased spouse’s estate must file Form 706, the United States Estate (and Generation-Skipping Transfer) Tax Return, even if no estate tax is ultimately due. This election must be made within nine months of the deceased spouse’s death.
How does the OBBBA impact estate planning for couples?
The OBBBA’s reduction of the federal estate tax exemption necessitates a reevaluation of estate planning strategies for many couples. Couples with estates approaching $30 million will need to implement more sophisticated planning techniques to minimize potential tax liability. This may include strategies such as gifting, the creation of trusts, and the utilization of qualified personal residence trusts (QPRTs). A wills attorney in San Diego can help you navigate these complex strategies and determine the best approach for your specific circumstances.
For couples with estates below $30 million, portability remains a valuable tool for maximizing tax benefits. However, it’s important to ensure that the portability election is made timely and correctly. Failure to do so could result in the loss of valuable exemption dollars. Furthermore, it’s crucial to consider the potential impact of state estate taxes, even though California does not have a state estate tax, as these can interact with the federal estate tax in complex ways.
What is Form 706, and how do I file it?
Form 706 is the form used to report the value of an estate to the IRS. Even if no estate tax is due, it’s often necessary to file Form 706 to elect portability. The form requires detailed information about the deceased spouse’s assets, liabilities, and beneficiaries. It’s a complex form that requires careful attention to detail. An attorney-led will drafting counsel can assist you in preparing and filing Form 706, ensuring that it’s accurate and complete.
The IRS provides detailed instructions for Form 706 on its website. However, it’s generally advisable to seek professional assistance, particularly if the estate is complex. Filing Form 706 incorrectly can result in penalties and delays. Furthermore, it’s important to understand the potential implications of filing Form 706, such as the disclosure of sensitive financial information to the IRS.
What happens if I don’t elect portability?
If you don’t elect portability, the surviving spouse will only be able to utilize their own federal estate tax exemption. This could result in significant estate tax liability if their estate exceeds $15 million. The loss of the deceased spouse’s unused exemption can be a substantial financial burden. Therefore, it’s crucial to ensure that the portability election is made timely and correctly. A testamentary drafting attorney in San Diego can help you understand the implications of not electing portability and develop a plan to mitigate potential tax liability.
The election is made on Form 706, and must be filed within nine months of the deceased spouse’s death. There are limited circumstances where an extension may be granted, but it’s best to file as soon as possible to avoid any potential issues. It’s also important to note that portability is not automatic; it must be affirmatively elected by the executor of the deceased spouse’s estate.
What other estate planning tools can help minimize estate tax liability?
In addition to portability, there are a number of other estate planning tools that can help minimize estate tax liability. These include gifting, the creation of trusts, and the utilization of qualified personal residence trusts (QPRTs). Gifting allows you to transfer assets to your beneficiaries during your lifetime, reducing the size of your estate. Trusts can provide asset protection and tax benefits, while QPRTs can help reduce the value of your estate by transferring ownership of your home to a trust.
A comprehensive estate planning strategy should be tailored to your specific circumstances and goals. A CPA-attorney integrating tax considerations into wills can help you develop a plan that minimizes estate tax liability and ensures that your assets are distributed according to your wishes. For example, in San Diego, where real estate values are high, utilizing a QPRT can be particularly effective in reducing estate tax exposure.
After 35+ years of practice, I’ve seen firsthand how proper estate planning can protect families from unnecessary tax burdens and ensure a smooth transition of wealth. It’s an investment that can provide peace of mind and financial security for generations to come.
What is a qualified personal residence trust (QPRT)?
A qualified personal residence trust (QPRT) is an irrevocable trust that allows you to transfer ownership of your home to a trust while retaining the right to live in the home for a specified period of time. This can effectively remove the home from your estate, reducing its value and potential estate tax liability. However, it’s important to understand the potential risks and benefits of a QPRT before implementing this strategy.
The IRS has specific requirements for QPRTs, and failure to comply with these requirements can invalidate the trust. It’s crucial to work with an experienced attorney to ensure that the QPRT is properly structured and funded. Furthermore, it’s important to consider the potential impact of a QPRT on your personal finances, such as your ability to qualify for a mortgage or other loans.
How can gifting strategies help reduce estate tax liability?
Gifting allows you to transfer assets to your beneficiaries during your lifetime, reducing the size of your estate. The IRS allows you to gift a certain amount of assets each year without incurring gift tax. As of 2025, the annual gift tax exclusion is $18,000 per recipient. You can also make larger gifts, but these may be subject to gift tax. However, any gifts exceeding the annual exclusion will reduce your lifetime gift tax exemption.
Gifting can be a powerful tool for reducing estate tax liability, but it’s important to consider the potential implications of gifting, such as the loss of control over the gifted assets. It’s also important to understand the potential impact of gifting on your personal finances, such as your ability to qualify for government benefits. A wills attorney analyzing statutory validity can help you develop a gifting strategy that minimizes estate tax liability and meets your specific needs.
What is the role of a trustee in managing an estate?
A trustee is responsible for managing an estate according to the terms of the trust. This includes investing the estate’s assets, paying creditors, and distributing assets to beneficiaries. The trustee has a fiduciary duty to act in the best interests of the beneficiaries. This means that they must act with prudence, loyalty, and impartiality. A successor trustee transition can be complex, particularly if the original trustee becomes incapacitated or dies.
The trustee is also responsible for filing tax returns for the estate. This can be a complex process, and it’s often advisable to seek professional assistance. Furthermore, the trustee can be held personally liable for any errors or omissions in managing the estate. Therefore, it’s crucial to choose a trustee who is knowledgeable, trustworthy, and experienced.
What are healthcare directives, and how do they differ from POLST/DNR orders?
Healthcare directives are legal documents that allow you to specify your wishes regarding medical treatment in the event that you are unable to make decisions for yourself. These can include a living will, which specifies the types of treatment you want or don’t want, and a durable power of attorney for healthcare, which designates someone to make medical decisions on your behalf. Healthcare directives vs. POLST/DNR distinctions are important to understand.
POLST (Physician Orders for Life-Sustaining Treatment) and DNR (Do Not Resuscitate) orders are specific medical orders that instruct healthcare providers on whether or not to provide life-sustaining treatment. POLST orders are typically used by individuals with serious illnesses, while DNR orders are used by individuals who do not want to be resuscitated. It’s important to discuss your healthcare wishes with your doctor and family members to ensure that your directives are clear and consistent.
What is a spendthrift provision, and how can it protect assets?
A spendthrift provision is a clause in a trust that prevents beneficiaries from assigning or transferring their interest in the trust. This can protect assets from creditors and lawsuits. Spendthrift provisions and creditor protection are important considerations when creating a trust. For example, if a beneficiary is facing a lawsuit, a spendthrift provision can prevent creditors from seizing their trust assets.
However, spendthrift provisions are not absolute. There are certain exceptions, such as child support obligations and government claims. It’s important to work with an experienced attorney to ensure that the spendthrift provision is properly drafted and enforceable. A wills attorney handling execution compliance can help you understand the potential benefits and risks of a spendthrift provision.
