What This Calculator Screens For in California

Most estates in California will never owe federal estate tax. The main use of this tool is triage: it helps you decide whether the estate is clearly below the federal threshold, clearly above it, or close enough that deductions and deeper planning may matter.

Probate questions and estate-tax questions are not the same thing. A family can have a probate problem with no tax issue, or a tax-sensitive estate that still transfers efficiently through trust planning.

No Separate State Estate Tax

This page focuses on federal screening because a separate state estate tax is not the main issue on this supported California page.

Federal Threshold

The current screen uses a federal basic exclusion amount of $15 million per person for 2026.

Return Context

Even when no tax is likely due, larger estates may still need more careful return and planning review than a rough calculator can provide.

What to Compare Alongside Estate Tax

Tax exposure is only one part of the estate plan. You still need to know the gross estate value, which assets pass outside probate, and whether the administration path is efficient for the family and the fiduciary.

After this estimate, compare the asset picture with the estate value calculator, review transfer planning with the revocable living trust guide, and use the California executor compensation page if the estate will also need administration cost modeling.

Frequently Asked Questions

Does California have a state estate tax?
California does not currently impose a separate state estate tax on these supported pages. Federal estate-tax analysis may still matter if the estate is large enough.
What federal threshold does this California calculator use?
For deaths in 2026, this calculator uses a federal basic exclusion amount of $15 million per person as the starting screen for whether deeper tax review may be needed.
Does every large estate owe federal estate tax?
No. Deductions, valuation issues, marital planning, charitable transfers, and the composition of the estate can all change the taxable amount. The calculator is a screening tool, not a filed return.
Is this the same as preparing Form 706?
No. Form 706 is the federal estate tax return. This estimator is only intended to help decide whether federal estate-tax review may be relevant before a more detailed analysis begins.
