M&A Advisory in Oklahoma

A 100% deduction on qualifying capital gains from: (a) Oklahoma real/tangible personal property held 5+ uninterrupted years; (b) stock or LLC/partnership interest in an Oklahoma-headquartered company held 2+ years (individuals) or 3+ years (entities/pass-throughs); or (c) sale of substantially all assets of an Oklahoma operating business. The target entity must have maintained its primary Oklahoma headquarters for at least 3 uninterrupted years before sale. Qualifying gains reported on Form 561; recapture income (§ 1245/IDC) does not qualify. On a $20M equity gain, this provision saves roughly $950,000 in 2025 state tax.

Oklahoma's top individual rate drops from 4.75% (2025) to 4.5% in 2026 under HB 2764, which also consolidates six brackets into three with revenue-triggered cuts toward eventual elimination. The corporate rate holds at a flat 4.0%. Under the Pass-Through Entity Tax Equity Act (HB 2665), S-corps and partnerships elect entity-level taxation via Form 586 at 4.75% (individual members) or 4.0% (corporate members), converting SALT into a federal above-the-line deduction. The PTE election and § 2358 deduction can be stacked for maximum after-tax efficiency.

Oklahoma repealed its corporate franchise tax ($1.25/$1,000 of capital, capped at $20,000) effective Tax Year 2024 under HB 1039 — though pre-2024 tail liabilities remain a routine diligence item. Oklahoma also adopted permanent 100% bonus expensing for qualified investments under Oklahoma statute, one of only two states (alongside Mississippi) to do so. This materially improves post-close depreciation economics for buyers acquiring Oklahoma operating assets, supporting higher bid multiples on asset-intensive targets in energy services and manufacturing.

Unlike most states where sellers face a structural disincentive to asset deals, Oklahoma's § 2358 deduction applies to both (i) stock/equity interest sales AND (ii) sales of all or substantially all assets of an Oklahoma entity, largely eliminating the state-level tax differential between deal structures. Buyers' § 338(h)(10) or § 336(e) step-up elections are therefore negotiable without the typical seller price concession driven by state tax divergence. Key exception: ordinary-income recapture on oil & gas equipment and intangible drilling costs (IDCs) does not qualify for § 2358 — a critical diligence item for E&P sellers.

Oil & gas operator transfers (OCC Form 1073), injection-well operator changes (Form 1073I), and force-pooling/spacing order assignments add 30–90 days to energy deal timelines. The new operator must file within 30 days of transfer; OCC has 30 days to approve; the prior operator remains legally responsible until certification is issued. Any open OCC compliance order blocks approval. Pre-sale OCC docket audits — resolving spacing-unit title defects and inactive-well plugging liabilities under OAC 165:10 — are table stakes for achieving premium multiples on E&P and oilfield services targets.

Oklahoma repealed its state estate tax effective January 1, 2010, and imposes no inheritance tax and no gift tax. Only the federal estate tax ($13.99M individual exemption in 2025, rising to $15M in 2026 under OBBBA) applies. This clean post-sale environment makes Oklahoma an effective domicile for Family Limited Partnerships (FLPs), Intentionally Defective Grantor Trusts (IDGTs), GRATs, and dynasty trusts funded at or before closing. Heirs who sell inherited Oklahoma business interests can often stack the §1014 stepped-up basis with a § 2358 deduction on any post-death appreciation.
