Fatti salienti
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.
Non residenti
- 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.
Thresholds & rates (2025)
The D.C. calculator in this hub mirrors the brackets used in the official D‑76 computation worksheets. As a quick guide:
| Taxable estate slice (approx.) | Marginal rate | Note |
|---|---|---|
| Above the zero‑bracket amount up to ~$5M | ~11.2% | Effective rate ramps from 0% as brackets phase in. |
| ~$5M to ~$10M | 12% – 15.2% | Multiple bands as per D‑76 worksheet. |
| $10M and above | 16% | Top marginal rate. |
For exact liability, use the DC calculator or the D‑76 worksheet.
Deadlines, extensions & penalties
| Articolo | Quando è previsto | Note |
|---|---|---|
| D‑76 / D‑76EZ | 10 months dopo la data del decesso | File and pay via MyTax.DC.gov. Attach federal Modulo 706 (if filed) and required documents. |
| Estensione del file (FR‑77) | Fino a +6 mesi to file | Request electronically by the original due date. Does not generally extend time to pay. |
| Interesse | From original due date | In generale 10% per year, compounded daily, on unpaid tax (special rule if a federal estate tax filing extension applies). |
| Sanzioni | After due date | Failure‑to‑file/‑pay: typically 5% per month or fraction thereof, up to 25% (see details in D.C. guidance). |
How to file
Electronic filing & attachments
File returns, payments, and extensions through MyTax.DC.gov. Typical attachments include: Letters of Administration, POA (if any), will/trusts, appraisals, death certificate, and a complete Modulo 706 (including Schedules A–O) if filed federally.
Marital deduction, portability & QTIP
- Portability: D.C. does non offer portability of a predeceased spouse’s unused D.C. exemption.
- QTIP: No separate state‑only QTIP election; generally follows the federal QTIP election and supporting schedules attached to the return.
