How to Form a Corporation in Oklahoma

What you file in Oklahoma

This page covers the state filing and the charges that follow it. For the procedural side — name availability, registered agent, bylaws and the federal EIN — see the formation guide and how to get an EIN, both of which apply to corporations as well as LLCs.

What it costs to incorporate and stay filed

State filing charges only. Corporate income tax and franchise tax are excluded — both depend on income or net worth, so no flat figure would be true for every corporation.

Oklahoma is the 3rd cheapest of 49 states on the incorporation filing fee alone. Nationally the fee runs from $35 in Montana to $300 in Texas, averaging $113.06. It is a one-off charge, so over five years it is usually outweighed by the recurring report fee and any annual franchise or minimum tax.

States that are cheaper to incorporate in

A cheaper filing fee elsewhere rarely saves money if you actually operate in Oklahoma. Every state sets its own threshold for what counts as transacting business, and where that threshold is met an out-of-state corporation is generally required to register as a foreign corporation — which would mean fees in both states rather than one. Whether it applies to you depends on facts this page cannot see, so check foreign qualification in Oklahoma before incorporating elsewhere to save on the filing fee.

Oklahoma corporation vs Oklahoma LLC

State filing charges only. Corporate income tax and franchise tax are excluded because both depend on income or net worth, so no flat figure exists for either entity.

Worth noticing: a corporation is $50 cheaper to file here than an LLC. That is the exception nationally — corporations are the cheaper filing in only 15 of the 50 states, the two entities cost the same in 25, and the LLC is cheaper in 10.

State taxes a Oklahoma corporation pays

Franchise or gross-receipts tax

None as of tax year 2024. Oklahoma's franchise tax was eliminated by HB 1039X (2023); the Oklahoma Tax Commission states tax year 2023 was the last year franchise tax returns were required and that 'starting with tax year 2024 and beyond, there will be no Oklahoma franchise tax filing requirement.' Foreign corporations and foreign not-for-profits still remit an annual registered agent fee to the OTC (collected on behalf of the Secretary of State) on Form 200-R.

What these totals leave out: the filing-charge figures on this page are what you pay the business filing office. They exclude corporate income tax and any franchise or gross-receipts tax, because both depend on income, net worth or receipts. The section above sets out what Oklahomalevies — or that it levies neither. Where a state's franchise tax carries a flat minimum, that minimum is an unavoidable annual cost these totals do not include, and over five years it can be the larger number.
