How do these options line up side by side?
| When | Step | Details |
|---|---|---|
| February to early March | Get an Enrollment Verification Number | Ask each school for an EVN per child. The school's registration on OkTAP lets it email the EVN to you. |
| Mar 15, 9:00 a.m. | OkTAP opens | File one application per student with the EVN, student and parent details and the 2025 federal AGI (for 2027-28). |
| First 60 calendar days | Priority review | Households at or below $150,000 come first, then students who held the credit the prior year, if they filed in the 60 days. |
| After the priority period | Remaining applications | Higher-income and later filers are reviewed in the order received while the annual cap has room. |
| Jun 15, 11:59 p.m. | Window closes | No late filings. A withdrawn application can't be reopened. |
| July 1 to Dec 31 | Changes | Approved families can redirect the credit to another participating school or adjust tuition on OkTAP; the new school submits fresh enrollment verification. |
| By Aug 30 | Payment | The Tax Commission sends the school one check for the whole credit, written to the taxpayer, no later than August 30. |
| Within 30 days of a move | Tell the Tax Commission | If the student leaves for a public school or a nonaccredited school, the taxpayer reports it electronically within 30 days; the credit for that period is recaptured. |
