US FederalCan I defer estate tax payments if my estate includes a family business?
Yes, you may defer estate tax payments for up to 15 years if your estate includes a qualifying family business, under IRC § 6166 — but this provision is not in the cited § 2001 statute.
What the Law Says
While 26 U.S.C. § 2001 imposes the federal estate tax and sets its rates, it does not address deferral. Deferral for family businesses is authorized under a separate provision: Internal Revenue Code § 6166. This section allows qualified estates to pay estate tax in installments over up to 15 years if the decedent owned a closely held business that comprises at least 35% of the adjusted gross estate.
To qualify, the business must be an interest in a trade or business carried on as a sole proprietorship or through a partnership, corporation, or other entity — and the decedent must have owned at least 20% of the business (by value or voting power) and materially participated in it for at least 5 of the 8 years before death.
The estate must file Form 706 and elect § 6166 within 2 years after the due date of the return (including extensions). Once approved, the first 5 years require only interest payments; principal payments begin in year 6 and continue annually through year 15.
Importantly, § 2001 itself only establishes the tax: 'A tax is hereby imposed on the transfer of the taxable estate of every decedent who is a citizen or resident of the United States.' It does not provide relief mechanisms like deferral.

What to Do
Confirm the family business meets the 35% value threshold of the adjusted gross estate.
Verify the decedent owned ≥20% and materially participated in the business for ≥5 of the prior 8 years.
File Form 706 (U.S. Estate Tax Return) and attach a written election for IRC § 6166 within 2 years of the return’s due date.
Pay interest-only installments for the first 5 years; begin principal + interest payments in year 6.
Maintain business continuity — dissolution or sale may trigger immediate payment of remaining tax.
