Oregon Revised Statutes Revenue and Taxation § 315.628

(1) A health care provider who enters into a contract for the first time on or after January 1, 2007, to provide health care services permitted under a TRICARE contract to patients enrolled in the TRICARE military health care system shall be allowed a one-time credit against taxes otherwise due under ORS chapter 316 in the amount of $2,500.

(2) A health care provider who has a contract to provide health care services permitted under a TRICARE contract to patients enrolled in the TRICARE military health care system shall be allowed a credit each tax year against taxes otherwise due under ORS chapter 316 in the amount of $1,000 if the health care provider actively participates in the TRICARE military health care system and each tax year provides health care services to at least 10 patients enrolled in the TRICARE military health care system. A health care provider who serves patients in a rural community, as defined by the Office of Rural Health, may provide health care services to fewer than 10 patients in a tax year and qualify for the credit.

(3) A health care provider may not receive a credit under subsections (1) and (2) of this section in the same tax year.

(4) A nonresident shall be allowed a credit under this section in the proportion provided in ORS 316.117. If a change in the status of a taxpayer from resident to nonresident or from nonresident to resident occurs, the credit allowed by this section shall be determined in a manner consistent with ORS 316.117.
