IRC §2056: Bequests to Surviving Spouse (Marital Deduction)

By Paul D. Diaz, EA, MBA · Updated

IRC §2056 is the unlimited marital deduction — property passing to a U.S.-citizen spouse passes estate-tax-free. It defers the tax to the second death; it doesn’t erase it.

Questions this section answers

Does everything left to my spouse escape estate tax?
Yes, if your spouse is a U.S. citizen and the interest isn’t terminable — §2056 is unlimited. The tax waits until the survivor’s death.
What is a QTIP trust?
Qualified terminable interest property: the spouse gets all income for life, no one can appoint away the remainder, and the executor elects §2056(b)(7) treatment — terminable, yet deductible.
My spouse isn’t a citizen — marital deduction?
Only up to the special annual exclusion (indexed, ~$190,000 range). Larger transfers need a qualified domestic trust (QDOT) to defer the tax.
