Full federal worksheet with credits, GST and payments · What each input means
Estimate federal estate tax after preparing the estate's valuations, deductions, gifts and valid additional exclusion. Historical liabilities, property in another jurisdiction and estate income require separate review.
The primary-source rule for New Mexico
New Mexico's published return calculates estate tax from the federal state death-tax credit, which no longer applies. That produces no current state estate tax. The old return and general agency page still discuss filing; confirm any estate-specific documentation request with TRD rather than treating a zero tax as blanket filing clearance.
Zero calculated tax does not settle old filing language
New Mexico's published RPD-41058 is a historical form tied to the federal state death-tax credit. Its formula has no positive credit to use for a current death, but the instructions still contain broad filing language. This page does not convert that old wording into blanket current filing clearance. Ask TRD to confirm any documentation request that applies to the particular estate.
The form's resident and nonresident allocation also shows why a generic estate total is not always enough for a state analysis. Location and legal classification of assets can matter, especially when an estate has real property or mineral interests in different jurisdictions. Keep the prepared property breakdown even though the current New Mexico transfer-tax calculation does not produce a positive amount.
For federal work, use the current IRS instructions rather than RPD-41058's historical federal references. A state return line labeled federal credit cannot be populated with the modern federal state-death-tax deduction. The worksheet below accepts an eligible deduction separately and requires prepared gift, valuation and exclusion information. It estimates federal tax without certifying New Mexico paperwork or final beneficiary distributions.
