Oklahoma Oil & Gas — SCOOP, STACK, and Severance Tax. Oklahoma is one of the most prolific oil and gas states, anchored by the SCOOP (South Central Oklahoma Oil Province) and STACK (Sooner Trend Anadarko Canadian Kingfisher) plays of the Anadarko Basin. Major operators include Continental Resources, Devon Energy, Chesapeake Energy, and dozens of mid-tier and royalty operations. Oklahoma's Gross Production Tax (severance tax) — 5% standard with a 2% incentive rate for new wells in their first 36 months — is a meaningful piece of Oklahoma operator economics, alongside federal IDC deductions, depletion (cost vs. percentage), and royalty/working-interest accounting. We support Oklahoma operators, royalty owners, and oilfield services companies with these specialized issues.
McGirt v. Oklahoma & Tribal Taxation. The 2020 U.S. Supreme Court decision in McGirt v.

Oklahoma CPA — Frequently Asked Questions
Do I need an Oklahoma-licensed CPA?

For oil and gas industry professionals (royalty owners, operators, services companies), aerospace and military professionals, real estate investors, agricultural operations, tribal members navigating McGirt-related issues, we confirm whether the work is tax, advisory, attest, employee-benefit-plan, or state-sensitive before accepting the engagement.

Oklahoma has a graduated personal income tax with a top rate of 4.75% on income above approximately $7,200 single / $12,200 joint. The OK corporate income tax is 4%. Form 511 (residents) or 511-NR (nonresidents/PY) is due April 15.
Does Oklahoma have a SALT-cap workaround?
Yes. Oklahoma was actually one of the earliest states to enact a Pass-Through Entity Tax (PTE) — effective for tax years beginning on or after January 1, 2019. Eligible S-corps and partnerships pay an entity-level tax tracking the top personal income tax rate, and members receive a corresponding credit on Form 511.
What special tax issues apply to Oklahoma oil and gas operations?
Oklahoma's oil and gas industry — anchored in the SCOOP/STACK plays of the Anadarko Basin and the historic oilfields of central Oklahoma — faces specialized issues: Oklahoma Gross Production Tax (severance tax — 5% standard, 2% incentive rate for newly drilled wells in the first 36 months), royalty interest and working interest accounting, intangible drilling cost (IDC) federal deductions, depletion (cost vs. percentage), and Oklahoma's specific tax treatment of severance income. We support Oklahoma operators, royalty owners, and oilfield services companies (Continental Resources, Devon Energy, Chesapeake Energy area) with these specialized issues.
How does the McGirt v. Oklahoma decision affect tribal taxation in Oklahoma?
The 2020 U.S. Supreme Court decision in McGirt v. Oklahoma — and its subsequent expansions — held that much of eastern Oklahoma remains "Indian Country" for federal jurisdictional purposes. The decision has implications for state taxation of tribal members residing on reservation land and for businesses operating on tribal lands across the Five Civilized Tribes territories (Cherokee, Chickasaw, Choctaw, Creek, Seminole). Tribal members may be exempt from Oklahoma state income tax on income earned on their tribe's reservation. The legal landscape continues to evolve. We work with Oklahoma tribal members and businesses on McGirt-related taxation issues.
When does my Oklahoma nonprofit need an audit?
Under Oklahoma's Solicitation of Charitable Contributions Act, charities registered with the Oklahoma Secretary of State are generally required to submit audited financial statements when annual contributions exceed $1,000,000, and reviewed financial statements when contributions are between $500,000 and $1,000,000.
