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
58 O.S. § 393 personal-property affidavit, § 241 court shortcut, and § 245 summary administration are treated as separate procedures.
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 — see the full Oklahoma transfer-on-death deed guide for the requirements, revocation, and alternatives. 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Oklahoma repealed its estate tax for deaths on or after January 1, 2010 and has no inheritance tax; only the federal estate tax applies, so the zero-tax status does not remove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.
