How OBBBA Changes Estate Planning

Emily just received a devastating call: her father’s hastily drafted codicil, attempting to add a substantial gift to her sister, was deemed invalid due to a lack of proper witnessing. The result? A costly, protracted probate battle, and Emily losing out on an expected $350,000 inheritance. This is a far too common scenario, but one that strategic estate planning can prevent. Many clients believe the federal estate tax is a distant concern, but the recent permanence of the One Big Beautiful Bill Act (OBBBA) requires a renewed look at how we structure wealth transfer.

For over three decades, I’ve helped families in Escondido and beyond navigate these complexities. As both an Estate Planning Attorney and a CPA, I bring a unique perspective. The tax implications of estate planning are often the most significant, and frankly, the most misunderstood aspect. We’re not simply about who gets what; it’s about how much they get after taxes. A well-structured plan minimizes those burdens.

What Does OBBBA Mean for Your Estate?

The OBBBA permanently established the Federal Estate Tax Exemption at $15 million per person ($30 million for couples) effective Jan 1, 2026. This eliminates the “2026 Sunset” fear, meaning this substantial exemption isn’t disappearing anytime soon. However, don’t mistake permanence for permission to ignore planning. The top tax rate remains at 40% for assets exceeding this permanent threshold, and that’s a considerable bite. Moreover, the exemption is indexed annually for inflation, but current economic conditions present potential volatility.

How Does the CPA Advantage Factor In?

This is where my dual role provides invaluable benefit. As a CPA, I understand step-up in basis. A step-up in basis means the cost basis of inherited assets is reset to the fair market value at the date of death. This avoids significant capital gains taxes when beneficiaries eventually sell those assets. This is a huge advantage, especially for appreciating assets like real estate or stocks. Properly valuing assets at the time of death is critical. Furthermore, accurately forecasting future capital gains rates is essential in determining the optimal time to gift assets.

What About Proposition 19 and Real Estate?

Even with a high estate tax exemption, real estate planning needs careful consideration, particularly with Proposition 19. Under Proposition 19, heirs only keep a parent’s low property tax base if they move into the home as their primary residence within one year. Critically, for 2026, the tax-free ‘basis boost’ is capped at $1,044,586 over the original taxable value; any value exceeding this adjusted cap results in a partial reassessment even if the child moves in. This can trigger unexpected property tax increases, negating some of the inheritance benefit. We often utilize trusts to mitigate this impact.

Probate Avoidance Strategies Still Matter

The high exemption reduces the number of estates subject to federal estate tax, but probate avoidance remains crucial. For deaths occurring on or after April 1, 2025, assets exceeding $208,850 generally trigger full probate. However, per Probate Code § 13050, this calculation MUST exclude all California-registered vehicles (regardless of value), boats, and up to $20,875 in unpaid salary. Furthermore, AB 2016 now allows a simplified ‘Primary Residence’ petition for homes valued up to $750,000, significantly expanding probate shortcuts.

Don’t Overlook Digital Assets and Incapacity Planning

Beyond traditional assets, digital assets are increasingly important. Per the Revised Uniform Fiduciary Access to Digital Assets Act (RUFADAA), custodians like Apple or Google are legally prohibited from granting executors access to the content of emails or private messages without ‘explicit written direction’ in the will or trust. Metadata (the ‘catalog’) may be accessible, but the private content remains locked without this specific legal trigger. Similarly, under both federal HIPAA and the California Confidentiality of Medical Information Act (CMIA), medical providers are strictly barred from sharing details with family unless a HIPAA Release is integrated into the Advance Healthcare Directive. Without this, a spouse may be forced to obtain an emergency court-ordered conservatorship just to speak with a surgeon.

What makes a California will legally enforceable when it matters most?

In California, a last will and testament is reviewed under probate standards that focus on intent, capacity, and execution. Clear drafting reduces ambiguity, limits misinterpretation, and helps families avoid unnecessary conflict during estate administration.

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.
