Date of Death Valuations for Tax Purposes

Step-Up Appraisals for Inherited Property Tax Basis

A step-up appraisal determines residential property value as of the date of death, establishing the tax basis heirs use when calculating capital gains if the property is later sold. Heirs, trustees, estate attorneys, and tax professionals use these appraisals to document the property's fair market value at the time of inheritance, which can significantly affect tax liability when the home is eventually transferred or liquidated. Desert Point Valuations prepares step-up appraisals that provide accurate historical market analysis supported by reliable data and thorough documentation.


The appraisal process involves a property observation appointment, analysis of recent comparable sales in your neighborhood, adjustment for property differences, and evaluation of current property. Because the effective date is in the past, the appraiser cannot rely solely on current listings or recent sales—historical records and archived data are reviewed to identify properties that sold near the valuation date. This analysis produces a defensible opinion of value that can be referenced in tax filings and withstand scrutiny by tax authorities.

Why Tax Basis Documentation Matters

The appraisal report includes property details, comparable sales from the date of death time period, and a final opinion of value that establishes the stepped-up tax basis. When heirs sell the property years later, capital gains tax is calculated based on the difference between the sale price and the stepped-up basis, not the original purchase price paid by the decedent. Without a professional appraisal documenting the date-of-death value, heirs may face higher tax liability or disputes with tax authorities who question the claimed basis.


Once the step-up appraisal is completed, the report can be shared with tax professionals, estate attorneys, and other advisors involved in estate settlement and tax planning. The documentation supports accurate tax return preparation and provides evidence if the valuation is ever challenged during an audit or estate tax proceeding. Desert Point Valuations delivers step-up appraisals with attention to the detailed historical analysis required for these assignments, ensuring that heirs and their advisors receive reliable documentation for tax purposes.


The firm schedules appraisals promptly and works with clients throughout Maricopa and Pinal counties to accommodate the timing needs of estate administration and tax filing deadlines.

Questions About Step-Up Appraisals

Step-up appraisals serve a specific tax purpose and understanding how the historical valuation process works helps heirs and advisors coordinate the assignment effectively.

  • What is a stepped-up tax basis?

    When property is inherited, the tax basis is adjusted to the fair market value on the date of death rather than the original purchase price. This adjustment, known as a step-up, reduces capital gains tax if the property is sold after inheritance.

  • How does the appraiser determine value from a past date?

    The appraiser researches sales of comparable properties that closed near the date of death in Mesa and surrounding areas. Market trend data and historical records help reconstruct what the property was worth on that specific date, even if the appraisal is ordered months or years later.

  • What documentation does the appraiser need?

    The appraiser needs the property address, the date of death, and access to the property for inspection or photographs from the relevant time period. Estate documents, prior appraisals, or photographs taken near the date of death can also support the analysis if the property's condition has changed significantly.

  • When should a step-up appraisal be ordered?

    The appraisal can be ordered anytime after the date of death, but earlier is better. Ordering the appraisal soon after inheritance ensures that comparable sales data from the relevant time period is still readily available and that the appraiser can document the property's condition more accurately.

  • How is the step-up appraisal used for tax purposes?

    The appraisal report establishes the stepped-up basis that heirs report on their tax returns when they sell the property. Tax professionals reference the report when preparing estate tax returns, gift tax returns, or capital gains calculations for the eventual sale.
