Okla. Stat. tit. 68, § 68-2357.501: Credit for firefighters' medical bills related to

cancer.

A. As used in this section:

1. “Cancer” means, but is not limited to, lung cancer, prostate

cancer, testicular cancer, skin cancer, colon cancer, breast cancer,

or any other form of cancer which is generally recognized as having

a higher risk of occurrence in a person who performs firefighting

services;

2. “Firefighter” means a person trained or certified as skilled

in the prevention and control of fires in residential and commercial

structures and naturally occurring fires commonly known as

wildfires; and

3. “Unreimbursed cost” means a portion of an expense which is

not covered or not fully covered under a health insurance policy and

for which a taxpayer expends money and is not able to recover the

expenditure.

B. For tax year 2026 and subsequent tax years, there shall be

allowed as a credit against the tax imposed pursuant to Section 2355

of Title 68 of the Oklahoma Statutes an amount equal to the

unreimbursed cost, not to exceed Two Hundred Fifty Dollars ($250.00)

per taxable year, incurred by a firefighter for the cost of medical

procedures to detect any form of cancer.

C. The credit authorized by this section shall not be used to

reduce the income tax liability of the taxpayer to less than zero

(0).

D. The credit authorized by this section, to the extent not

used, may be carried over, in order, to each of the five (5)

subsequent tax years.

E. For tax year 2028 and subsequent tax years, the total amount

of credits authorized by this section used to offset tax shall be

adjusted annually to limit the annual amount of credits to One

Million Five Hundred Thousand Dollars ($1,500,000.00). The Oklahoma

Tax Commission shall annually calculate and publish by the first day

of the affected year a percentage by which the credits authorized by

this section shall be reduced so the total amount of credits used to

offset tax does not exceed One Million Five Hundred Thousand Dollars

($1,500,000.00) per year. The formula to be used for the percentage

adjustment shall be One Million Five Hundred Thousand Dollars

($1,500,000.00) divided by the credits claimed in the second

preceding year.

F. In the event the total tax credits authorized by this

section exceed One Million Five Hundred Thousand Dollars

($1,500,000.00) in any calendar year, the Tax Commission shall

permit any excess over One Million Five Hundred Thousand Dollars

($1,500,000.00) but shall factor such excess into the percentage

adjustment formula for subsequent years.
