Oklahoma salary history ban: no state law, 40 O.S. 198.1 and the Tenth Circuit's rule on prior pay

Oklahoma has no state law that bars private employers from asking job candidates about their salary history, as of October 2026. The Legislature's compiled Title 40 (Labor), which includes laws through the 2025 session, has no wage history provision, and the Oklahoma City, Tulsa and Norman codes have none either. What Oklahoma does have is a 1965 equal pay statute, 40 O.S. 198.1, and a federal appeals court whose rule on prior pay is unusually clear: in Riser v. QEP Energy (2015), the Tenth Circuit said the Equal Pay Act "precludes an employer from relying solely upon a prior salary to justify pay disparity." Asking is lawful; pricing an offer off the answer is risky.

Is it illegal to ask about salary history in Oklahoma?

No. The Legislature publishes Title 40 as a single compiled document, Oklahoma Statutes Title 40 (Labor); it contains no section on salary history, wage history or pay history questions. An employer may ask, a candidate may decline, and nothing in state law protects a candidate who declines. Oklahoma's broader hiring rules are in hiring employees in Oklahoma.

What does Oklahoma's own equal pay law say?

Section 198.1 of Title 40, unchanged since Laws 1965, c. 494, reads:

"It shall be unlawful for any employer within the State of Oklahoma to willfully pay wages to women employees at a rate less than the rate at which he pays any employee of the opposite sex for comparable work on jobs which have comparable requirements relating to skill, effort and responsibility, except where such payment is made pursuant to a seniority system; a merit system; a system which measures earnings by quantity or quality of production; or a differential based on any factor other than sex."

Three points for recruiters:

• "Comparable work." The state test is "comparable" work, where the federal Equal Pay Act says "equal work."
• "Willfully." The state offense requires a willful underpayment.
• Small penalties, real enforcement. Section 198.2 makes the Commissioner of Labor responsible for enforcement and makes a violation a misdemeanor with a fine "not less than Twenty-five Dollars ($25.00) nor more than One Hundred Dollars ($100.00)." Section 199 makes it a misdemeanor to discharge or penalize an employee for filing a complaint or testifying to enforce these sections.

The state penalty is small. The federal exposure for the same pay gap is not, which is why the Tenth Circuit's rule matters more.

How do federal courts in Oklahoma treat prior pay?

The federal Equal Pay Act, 29 U.S.C. 206(d)(1), allows a pay difference for equal work only under a seniority, merit or production system or "a differential based on any other factor other than sex," and the employer must prove the defense. Whether prior pay counts is where the federal appeals courts differ, and Oklahoma sits in the Tenth Circuit.

In Riser v. QEP Energy, No. 14-4025, decided January 27, 2015, the Tenth Circuit reversed summary judgment for an employer that pointed to a male comparator's prior salary. The court wrote that "an individual's former salary can be considered in determining whether pay disparity is based on a factor other than sex," but that the Equal Pay Act "precludes an employer from relying solely upon a prior salary to justify pay disparity," and that a 31% gap "cannot be justified simply by" the comparator's prior salary. The case arose in Utah, but the rule binds federal courts in Oklahoma too.

The EEOC takes the same view. Its Compliance Manual section on compensation discrimination, issued in 2000 and still on eeoc.gov as of October 2026, says "Prior salary cannot, by itself, justify a compensation disparity." Title VII, at 42 U.S.C. 2000e-2(a), separately bars compensation discrimination by employers with 15 or more employees.

The practical reading: in Oklahoma you may ask, and you may weigh the answer, but if a woman ends up paid less than a man for equal work, "he earned more at his last job" will not carry the defense alone. Offers need other, documented, job-related reasons.

What should a hiring manager write down when setting an offer?

Riser turned on the employer's inability to explain a gap with anything but the comparator's old salary. A short note made when the offer is set closes that gap. For each Oklahoma offer, record:

• the posted or budgeted range for the role and where in it the offer sits;
• the job-related reasons for that position, such as a licence, certification, years in the specific work, or a skill the role description lists;
• a check against current employees doing equal or comparable work, and why any difference is justified; and
• if prior pay was considered at all, the other factors that were weighed alongside it.

None of this needs the candidate's current salary. It needs the reasons, written at the time, which is also what recruiters answering salary questions lean on when a candidate pushes for more.

Can Oklahoma cities pass salary history bans?

We found none that has. Oklahoma's preemption statute, 40 O.S. 160, added by Laws 2014, c. 40, says the Legislature "occupies and preempts the entire field of legislation in this state touching in any way mandated minimum wage and employee benefits regarding mandatory minimum number of vacation or sick leave days," and bars any municipality from setting a minimum wage or a mandatory number of vacation or sick days. It does not mention hiring questions. We searched the Oklahoma City, Tulsa and Norman codes on Municode for "salary history" and "wage history" in October 2026 and found no provision.

Do other states' bans reach Oklahoma recruiters?

They can, when the work happens there. Colorado's ban covers every employer with someone working in Colorado, so a remote hire who will work from Denver is under it; see the Colorado salary history ban. Kansas City, Missouri, has its own ordinance for employers with six or more employees, listed with other cities in salary history ban states. Colorado also requires pay ranges in postings, which affects remote ads; see pay transparency for remote jobs.

Should an Oklahoma recruiter ask about current pay?

Staffing firms recruiting across state lines are better served by one no-history process than by tracking which candidate lives where. Agency licensing and screening rules are covered in Oklahoma staffing agency licensing, Oklahoma background check laws and E-Verify requirements in Oklahoma.

An Oklahoma script

Opening the pay topic

"This role pays $52,000 to $60,000 plus benefits (example figures). What are you targeting?" More wording is in salary expectation questions.

When the hiring manager wants to match the candidate's old salary

"We can consider it, but it can't be the only reason for where the offer lands. Let's base it on the range and her certifications, and write that down."

When the candidate volunteers current pay

"Thanks. We set pay from the role, so what matters is what you need to make the move." Record the expectation only.

Oklahoma summary

Oklahoma checklist

1. Decide as a policy not to ask about current or past pay.
2. Share the range and ask for expectations.
3. Never let prior pay be the only reason an offer differs from a colleague's; write down the job-related reasons.
4. Keep volunteered figures out of the ATS and submittals; see what not to write in interview notes.
5. Check the law where a remote hire will work, starting with Colorado.
