Who is taxed & who must file?

Residents (domiciled in D.C.)

  • D.C. estate tax applies to the worldwide gross estate (with federal‑style deductions/credits) when above the D.C. zero‑bracket amount.
  • Personal representative files D‑76 or D‑76EZ and pays any tax due.

Nonresidents

  • D.C. taxes D.C.‑situs real property and tangible personal property. Intangibles of nonresidents (e.g., marketable securities) are generally not D.C.‑situs.
  • File D‑76 if D.C. estate tax is due.
