1. Tax 1.1 Tax Regimes

spouses who are US citizens are exempt without limit under the marital deduction. The annual exclusion for gifts to a non-citizen spouse is USD194,000 for 2026. Transfers to qualifying charities are deductible without limit for both gift and estate tax purposes. 1.3 Income Tax Planning A state level opportunity is the Oklahoma capital gain deduction under 68 O.S. (Oklahoma Statutes) Section 2358. An individual may deduct the full gain from the sale of Oklahoma real property or tangible personal property owned for at least five uninterrupted years, and the full gain from the sale of stock or an owner - ship interest in an Oklahoma-headquartered company owned for at least two uninterrupted years. The ele - ments are technical. For example, the company must have kept its primary headquarters in Oklahoma for at least three uninterrupted years before the transac - tion, non-individual taxpayers face a three-year rather than two-year holding requirement, and gain flowing through a partnership or S corporation qualifies only if both the owner’s holding period in the entity and the entity’s holding period in the asset satisfy the statute. For a founder selling a closely held Oklahoma com - pany, the deduction can eliminate state income tax on the transaction, and the expanded federal qualified small business stock exclusion can work alongside it, so the holding clocks should be confirmed well before a sale. 1.4 Pre-Immigration and Exit Planning For an individual moving into Oklahoma, planning is mostly about timing and proof. Oklahoma taxes resi - dents on all income and nonresidents only on Okla - homa-source income, so a person expecting a large recognition event from intangible assets may prefer to close the transaction before establishing Oklaho - ma domicile, while a client planning to qualify for the capital gain deduction may want to start the holding period clocks early. Part-year resident returns allocate income around the move date. For a departing individual, Oklahoma imposes no exit tax. The work is establishing that domicile has actually changed, because intent is tested against objective conduct such as homestead filings, voter registration, driver’s licenses, and where family and business life actually occur.

Oklahoma has no estate tax, no inheritance tax, no gift tax, and no generation-skipping transfer tax. Wealth transfer taxation for Oklahoma clients is a federal matter. Oklahoma imposes a personal income tax on individuals and on estates and trusts. Beginning with tax year 2026, the legislature consolidated six brack - ets into three and reduced the top marginal rate from 4.75% to 4.5%, with the top rate reached at modest income levels. The same legislation created a trigger that cuts rates a quarter point at a time when rev - enue collections exceed the prior high-water mark by enough to fund the cut, subject to annual certification and nullified if a revenue failure occurs, with the stated goal of eliminating the personal income tax altogether. The corporate income tax rate is a flat 4%, and the state franchise tax was repealed beginning with tax year 2024. Local governments fund themselves primarily through ad valorem property taxes, which are modest by national standards and subject to constitutional caps on annual valuation increases, with a valuation freeze available to income-qualified seniors. State and local sales and use taxes apply to most purchases, although the state portion of the sales tax on grocer - ies was eliminated in 2024. No Oklahoma municipality levies a local income tax. 1.2 Exemptions As Oklahoma imposes no transfer taxes of its own, exemption planning is federal. Each donor may give USD19,000 per recipient in 2026 without using any lifetime exemption, and spouses may combine their annual exclusions. Direct payments of tuition to an educational institution or of medical expenses to a provider are excluded from gift tax without limit under Section 2503 (e) of the Internal Revenue Code and are also excluded from generation-skipping transfer tax. The federal lifetime exemption of USD15 million per person covers gifts during life and transfers at death, and a deceased spouse’s unused exemption may be ported to the survivor by a timely election, with a sim - plified late election available for up to five years for estates below the filing threshold.
