Estate Tax vs Inheritance Tax

Emily just received a frantic call from her brother, Dax. Their mother passed away unexpectedly, and the initial probate estimate came back shockingly high – over $150,000 in potential estate taxes. Emily is convinced there’s a mistake; her mother wasn’t wealthy, and she’s devastated by the thought of losing such a significant portion of her inheritance to taxes. The problem? Her mother had a handwritten codicil attempting to update her estate plan, but it wasn’t properly witnessed, rendering it legally invalid and throwing the entire estate into a complex, costly probate battle.

Understanding the difference between estate and inheritance taxes is crucial for effective wealth transfer planning. While often used interchangeably, they are distinct taxes levied on different aspects of wealth. As an estate planning attorney and CPA with over 35 years of experience here in Temecula, I frequently guide clients through these complexities, leveraging my accounting background to minimize tax burdens and maximize what passes to their heirs. The advantage of having a CPA involved isn’t just about compliance; it’s about strategically utilizing concepts like step-up in basis and accurate valuation to significantly reduce capital gains taxes down the line.

What is Estate Tax and Who Pays It?

The estate tax is a federal tax imposed on the transfer of a deceased person’s assets before distribution to heirs. It’s levied on the estate itself, meaning the estate’s executor is responsible for paying it from the estate’s assets. This is a tax on the right to transfer wealth, not on the wealth received. Currently, the One Big Beautiful Bill Act (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, though the top tax rate remains at 40% for assets exceeding this permanent threshold, which is now indexed annually for inflation.

What is Inheritance Tax and Who Pays It?

Inheritance tax, on the other hand, is levied on the recipient of the assets – the heir. It’s a tax on the right to receive wealth. Unlike the federal estate tax, inheritance taxes are primarily levied at the state level. Currently, only a handful of states impose an inheritance tax, and the rules vary significantly. Some states exempt close family members (like spouses and children) while taxing more distant relatives or non-family beneficiaries. This can create complex planning scenarios, especially if beneficiaries reside in different states.

How Do They Differ in California?

California does not have a state inheritance tax. However, it does have an estate tax, although the threshold is quite low. 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. This means even relatively modest estates can be subject to probate fees, which are calculated as a percentage of the estate’s gross value. Proper planning, such as utilizing trusts, can help avoid these fees and associated costs.

What About Proposition 19 and Its Impact?

Proposition 19 added a layer of complexity to California property tax rules. While it allows some homeowners to transfer their low property tax base to a new home, it also impacts inheritance. 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 create unexpected tax liabilities and necessitates careful evaluation of the property’s value and the heir’s intentions.

What About Business Assets and the CTA?

If the estate includes ownership in a limited liability company (LLC) or other business entity, there are additional considerations. Under the Corporate Transparency Act (CTA), all non-exempt small businesses must maintain active BOI Reports with FinCEN. Upon the death of a member, the estate or successor has exactly 30 days from the date the estate is settled to file an updated report; failure to meet this window triggers non-waivable fines of $500 per day. Properly structuring business ownership and ensuring compliance with the CTA is vital to avoid penalties and maintain the business’s continuity.

Digital Assets: A Modern Complication

Increasingly, estates include digital assets – online accounts, cryptocurrency, and digital content. 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. Failing to address digital assets in your estate plan can lead to significant delays and lost assets.

Protecting Your Loved Ones: Incapacity Planning

Estate planning isn’t just about what happens after death; it also encompasses incapacity planning. 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. A comprehensive incapacity plan ensures your wishes are respected and your family can make informed decisions on your behalf if you become unable to do so.

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

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.
