Undercroft Montessori School, Tulsa OK: Tax Credit & LNH Status

About this record. We combined the federal Private School Survey (2023-24, or 2021-22 where a school skipped the newer survey), the Oklahoma Tax Commission's participating-school file dated September 3, 2026 and OSDE's LNH approved list dated October 28, 2026, as downloaded on October 30, 2026. Neither agency collects tuition, so check prices with the school directly.

Yes. Undercroft Montessori School shows up in the OkTAP registration file the Tax Commission posted on September 3, 2026, which means it can email families the Enrollment Verification Number that the OkTAP application needs. For 2027-28 you would file between 9 a.m. on March 15 and 11:59 p.m. on June 15, 2027, and the credit would be $5,000 to $7,500 per child depending on household income, never more than this school's tuition and fees.

OSDE's Lindsey Nicole Henry list dated October 28, 2026 also includes Undercroft Montessori School, for grades PK-8. Families of a child on an IEP, or of a service member's child who moved here on PCS orders, can apply online in PCG Scholar; OSDE's posted cutoff for the current school year is December 1.
