Quick Answer: The federal alternate valuation election generally uses values six months after death, or an earlier disposition date for assets sold or distributed during that period. It must reduce both the gross estate and applicable estate and generation-skipping transfer taxes after credits. Executors need date-of-death and alternate-date values, with eligibility and consequences reviewed by their tax professional.

Most executors never hear about the alternate valuation date, and in many estates it does not apply or does not help. Where it does apply, it is one of the more consequential elections available, and it has a structural feature that surprises people: to decide whether it benefits the estate, you generally have to know both values, which means the valuation work can double. Here is the shape of it. The eligibility and tax analysis belong with the estate's attorney or tax professional.
What Does the Alternate Valuation Election Do?
Estate assets are normally valued as of the date of death. The election itself is explained in date of death and choosing an alternate valuation date. The federal election generally uses values six months after death, with an earlier disposition date for property sold or distributed during that period. The purpose is relief: if asset values declined after the death, valuing at the later date can reduce the taxable estate. It is not a menu option to be chosen freely; the election must lower both the gross estate and the relevant federal estate and generation-skipping transfer taxes after credits, and it applies to the estate as a whole rather than selected assets. The timing rules are covered in the six-month window and alternate valuation timing rules executors discover too late.
Why It Is Not Always Beneficial
A qualifying election reduces the relevant federal estate taxes and generally changes inherited-property basis to the applicable elected value. A lower reported value can mean a larger capital gain when the property is eventually sold. That tradeoff runs through the stepped-up basis and the tax benefit most heirs do not know they have until it is too late. Whether the election helps depends on whether the estate is taxable at all, the size of the decline, the heirs' intentions for the property, and their own tax positions. This is precisely the kind of tradeoff that requires professional tax analysis rather than intuition.
The Practical Consequence for Valuation Work
To evaluate the election, the executor typically needs a defensible value as of the date of death and a defensible value as of the alternate date. Both are retrospective, both require reconstructing the market as it stood on a past date, and both require the appraiser to understand the property's condition at each point. Ordering the analyses together can avoid duplicated work; the fee depends on the assignment.
Why Condition Documentation Becomes Critical
With two dates in play, the question of how the property changed between them becomes live. If heirs cleaned, repaired, or emptied the home during that interval, the appraiser has to distinguish market movement from physical change. Dated photographs taken before changes, together with records of repairs and other condition evidence, help support that distinction. Executors who document the property early preserve the ability to make this election properly.
If an estate you are administering held property through a period when values may have moved, ask the estate's attorney whether the alternate valuation date is worth evaluating. We prepare retrospective estate valuations across Eastern Massachusetts, including Brookline and the surrounding communities. If it is, plan for two retrospective valuations and make sure the property's condition at both dates is documented. This is an area where Adam and the estate's tax professional should both weigh in before anything is filed.
What is the alternate valuation date?
It is a federal estate-tax election generally using values six months after death, with earlier disposition dates where required. It applies estate-wide and requires reductions in both the gross estate and applicable federal estate and generation-skipping transfer taxes after credits.
Does using the alternate valuation date always save money?
No. Although a qualifying election reduces the relevant federal estate taxes, a lower inherited basis can increase a later capital gain. Whether it benefits a particular estate depends on facts a tax professional needs to evaluate.
Do I need two appraisals to use the alternate valuation date?
The analysis needs support for both date-of-death and applicable alternate values. An appraiser may report multiple effective-date opinions in one engagement, rather than necessarily issuing two separate reports. Confirm the required scope and fee with the appraiser and estate's tax professional.
