Do I Still Need a Bypass Trust in 2026

The short answer is: it depends, but for most Californians, the traditional bypass trust is becoming obsolete. For decades, estate planning attorneys routinely included bypass (or “A-B”) trusts within revocable living trusts to utilize the federal estate tax exemption. The goal was to shield assets from estate taxes by funding a separate trust for one spouse, effectively doubling the exemption amount. However, the federal estate tax exemption has increased dramatically, and in 2026, it’s scheduled to revert to a much lower level.

Currently, in 2024, the federal estate tax exemption is $13.61 million per individual. This means a married couple can collectively transfer over $27 million without triggering federal estate taxes. While the exemption is scheduled to sunset on January 1, 2026, reverting to approximately $7 million (adjusted for inflation), the planning implications aren’t as drastic as many believe. California also has a state estate tax, but it’s largely “stacked” on top of the federal exemption, meaning most Californians won’t be subject to either.

When is a Bypass Trust Still Useful?

If your estate, even with the reduced 2026 exemption, is projected to exceed the applicable exclusion amount, a bypass trust – or a more modern variation – can still be a valuable tool. However, the traditional A-B trust structure is often cumbersome and unnecessary. We now typically employ more flexible credit shelter trusts, or strategies incorporating portability of the unused exemption amount.

Portability allows a surviving spouse to “port” the deceased spouse’s unused exemption amount to their own estate, effectively combining the exemptions. This simplifies estate planning significantly, often eliminating the need for a separate bypass trust altogether. But portability requires timely filing of an estate tax return (Form 706) even if no tax is due, a step many people overlook.

What About California’s Unique Estate Tax Landscape?

California’s estate tax rules add another layer of complexity. While the state exemption mirrors the federal exemption, the way it interacts with the federal credit can create unexpected tax liabilities. Furthermore, if a Will is invalidated, assets fall under intestacy; however, for deaths on or after April 1, 2025, estates with personal property under $208,850 (per CPC § 13100) may still bypass full probate via affidavit.

The Risks of a Defective Will or Trust

Harvey’s situation highlights the critical importance of proper execution. A seemingly minor error – like an improperly completed jurat on a Will or a missing signature on a trust amendment – can invalidate the entire document. Unless there are two other disinterested witnesses, a beneficiary witness (as defined in California Probate Code § 6112) triggers a legal presumption of duress or fraud. Furthermore, the court may validate a signature-defective Will if there is “clear and convincing evidence” of the testator’s intent, as per Probate Code § 6110(c)(2), but this requires a costly court petition and is not a guaranteed safety net. That’s why we always emphasize meticulous attention to detail during the signing process.

I’ve practiced as an Estate Planning Attorney & CPA for over 35 years, and I’ve seen firsthand how a seemingly minor oversight can have devastating consequences. My CPA background is particularly valuable here. Proper planning allows me to maximize the step-up in basis for inherited assets, minimizing capital gains taxes. It also ensures accurate asset valuation, crucial for both estate and gift tax purposes.

What About Digital Assets and RUFADAA?

Don’t forget about digital assets. As of 2025, California law (CPC § 871) was expanded to grant fiduciaries power over digital accounts, thanks to RUFADAA 2.0 (SB 1458). However, you must still grant explicit RUFADAA powers in your Will or Trust to bypass federal privacy blocks.

Self-Proving Affidavits and Streamlined Probate

To further streamline the probate process, we always include a self-proving affidavit. As outlined in Probate Code § 8220, this affidavit allows the Will to be admitted to probate without the testimony of the subscribing witnesses, saving time and expense.

In conclusion, while the traditional bypass trust may not be necessary for many Californians, proper estate planning remains essential. The key is to work with an experienced attorney who can assess your individual circumstances, anticipate future changes in the law, and ensure your wishes are carried out efficiently and effectively. Don’t let a technicality derail years of careful planning, as happened to Harvey’s family.

What does a California probate court look for when interpreting testamentary intent?

In California, a last will and testament operates within a probate system that emphasizes intent, clarity, and procedural compliance. When properly drafted, a will does more than distribute property—it creates legally enforceable instructions that guide courts, fiduciaries, and beneficiaries through administration with fewer disputes and less uncertainty.

When a will is drafted with California probate review in mind, it becomes a stabilizing roadmap rather than a source of conflict. Clear intent, proper authority, and compliant execution protect both families and estates.
