Estate Tax vs Inheritance Tax

Keith just received a notice from the IRS demanding over $1.2 million in estate taxes, despite believing his wife’s estate was well under the exemption threshold. He’d relied on outdated information and failed to account for the complexities of valuation and the subtle but crucial differences between estate tax and inheritance tax—a mistake costing his family dearly.

As an estate planning attorney and CPA with over 35 years of experience here in Corona, California, I frequently encounter this confusion. While often used interchangeably, “estate tax” and “inheritance tax” are distinct concepts with vastly different implications. Understanding this difference is critical for effective tax planning, especially as the legal landscape evolves.

What Exactly Is Estate Tax?

Estate tax is levied on the transfer of assets from a deceased person’s estate before distribution to heirs. It’s an excise tax on the right to transfer property, meaning the estate itself, not the beneficiaries, pays the tax. The federal estate tax is the most significant, but several states also impose their own estate taxes.

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. This generous exemption means very few estates will actually be subject to federal estate tax. However, failing to plan for the possibility – or miscalculating the estate’s value – can still lead to significant penalties.

And What About Inheritance Tax?

Inheritance tax, on the other hand, is imposed on the beneficiaries who receive assets from a deceased person’s estate. The tax is based on the amount and relationship of the beneficiary to the deceased. Spouses, children, and other close relatives are often exempt or taxed at a lower rate, while more distant relatives or non-relatives may face higher rates. California does not currently have a state-level inheritance tax.

How Do They Differ in Practice?

The key distinction lies in who pays the tax. Estate tax is paid from estate assets before distribution. Inheritance tax is paid by the individual receiving the inheritance. This affects cash flow and the overall net value received by beneficiaries. Consider a scenario where an estate is subject to both: the estate’s liquid assets will be reduced by the estate tax, and then the beneficiaries will be responsible for paying their share of the inheritance tax on what remains.

The CPA Advantage: Beyond Just Tax Filing

As a CPA as well as an attorney, I bring a unique perspective to estate planning. It’s not just about minimizing estate tax; it’s about maximizing the ‘step-up in basis’ for inherited assets. This means that inherited assets are revalued to their fair market value at the date of death, potentially eliminating significant capital gains taxes when those assets are later sold. Accurate valuation is critical, and a CPA’s expertise is invaluable in ensuring you’re not leaving money on the table. Furthermore, proper planning can minimize exposure to ongoing property tax increases, particularly relevant given Proposition 19.

Proposition 19 and Its Impact on 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.

Probate and Avoiding Estate Tax Triggers

Understanding probate is also 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.

Careful planning can minimize both estate tax and inheritance tax liabilities. A well-structured estate plan, combined with astute tax advice, will ensure your wishes are carried out efficiently and that your family receives the maximum benefit from your hard work.

How do California courts decide whether a will reflects true intent or creates ambiguity?

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.

For California residents, understanding how intent, authority, and compliance interact is one of the most effective ways to protect family harmony and estate integrity. A will that anticipates probate scrutiny is far more likely to be honored as written and far less likely to become the source of unnecessary conflict.
