The state
Oklahoma puts no income or franchise tax on an S corporation with a resident owner. The franchise tax on corporations ended after tax year 2023, so the election adds no franchise filing and no Oklahoma fee.
You report the business income on your Oklahoma individual return either way. The top rate is 4.5% for tax year 2026.
Oklahoma follows the federal S election. The S corporation files its annual return on Form 512-S.
Unemployment tax on your salary
Unemployment insurance: 1.5% for a new employer on the first $25,000 of wages in 2026. The business pays it and cannot take it out of your pay.
Corporate officers are covered, including officers of S corporations. An LLC member’s wages are taxed the same way federal unemployment tax treats them, so the salary an electing LLC pays you is covered.
The optional pass-through entity tax
An S corporation, including one with a single owner, can elect to pay Oklahoma tax itself at 4.5% for 2026 on Form 586. You then leave that income off your own Oklahoma return. The calculator leaves it out.
Worked examples
A single-member LLC owner, single filer, 22% federal bracket, default payroll and return costs. The figure is total tax and added costs as an S corporation compared with staying as you are.
