60-day creditor period — how New Mexico compares: New Mexico's 60-day UPC creditor period (from first publication) is significantly shorter than non-UPC states. California and Oregon have 4-month creditor periods; Florida's summary administration has a 3-month period. New Mexico's 60-day framework can dramatically shorten the overall estate timeline when all other tasks are managed promptly.

No New Mexico estate tax: New Mexico has no state estate tax or inheritance tax. The federal estate tax only applies if the gross estate exceeds approximately $13.99 million (2025). Most Personal Representatives in New Mexico have no estate tax returns to file — only the income tax returns (PIT-1 and possibly FID-1) apply.

Community property and the Inventory deadline: New Mexico's community property rules affect the Inventory. Only the decedent's interest in each asset is inventoried: separate property in full, community property at the decedent's half-interest. The surviving spouse's half of community property is NOT part of the estate and should not appear in the Inventory. This distinction matters for the stepped-up basis calculation on inherited assets under IRC § 1014.

Factors That Can Extend the Timeline

Community property disputes: If the characterization of property (community vs. separate) is disputed, formal probate and court resolution may be required
Real estate sales: Listing, marketing, and closing on estate real estate typically adds 2–4 months
Disputed creditor claims: Disallowed claims that are appealed require court intervention
Estate income tax: If the estate earns income across multiple calendar years, a FID-1 return is needed for each year before closing
Missing heirs: Locating all heirs to provide required notice can delay distributions
Out-of-state assets: New Mexico real estate is handled in New Mexico; real estate in other states requires ancillary probate in those states
