Estate tax
Oklahoma does not levy its own estate tax. An estate here is subject only to the federal estate tax, which most estates never owe — the federal exclusion is measured in the millions. See the federal lifetime exemption for how that works.
Inheritance tax
Oklahoma has no inheritance tax — beneficiaries are not taxed on what they receive by the state. Oklahoma imposes no inheritance tax.
Probate basics
A small-estate affidavit under Okla. Stat. tit. 58 § 393 is available when the Oklahoma property, less liens, does not exceed $50,000 (personal property, debts, and securities only). Oklahoma also offers summary administration for smaller estates (tit. 58 § 241 et seq.).
Oklahoma is a common-law (separate-property) state for ownership between spouses. A transfer-on-death deed for real estate is Available Okla. Stat. tit. 58 § 1251 et seq. (Nontestamentary Transfer of Property Act) · 2008. The probate deadlines for this state — filing the will, the creditor-claim window, the inventory — are cited in the Executor & Heir’s Guide.
State-specific quirks
A 9-month acceptance deadline on TOD deeds
An Oklahoma transfer-on-death deed must be recorded before the owner's death, and the beneficiary must then record an acceptance affidavit within nine months of the death (Okla. Stat. tit. 58 § 1252); if not, the interest reverts to the estate.
The $50,000 affidavit does not transfer real estate
Section 393 covers only personal property, debts, and securities — it does not convey real property, which must pass by TOD deed, joint tenancy, a trust, or probate.
No death tax, but confirm the federal picture
Oklahoma repealed its estate tax for deaths on or after January 1, 2010 and has no inheritance tax; only the federal estate tax applies, so the zero-tax status does not remove federal exemption planning.

Sources & methodology
Methodology & sources
Every tax figure on this page links to the primary source it was verified against — a Oklahoma statute or department-of-revenue page — with that source’s own effective date. Aggregator round-ups are never used as a source. State death and probate law changes every legislative session; this page carries the date it was last re-verified, and any figure that could not be confirmed from a primary source is flagged for you to check with the state rather than guessed. See our editorial standards.
This page is educational and is not legal or tax advice. Whether a death tax applies turns on residency, where property sits, and how title is held — details a general page cannot resolve. Confirm your own situation with a professional licensed in Oklahoma.
