What does a Tulsa parent need before March 15, 2027?
Collect one EVN per child from the school, the parent and student information OkTAP asks for, and your AGI from the 2025 federal return, since a 2027-28 application looks back two tax years.
What do benefit households need?
The parent filling out the application needs the case number or member ID and a Confirmation of Benefits for SNAP, TANF or SoonerCare/SoonerSelect, which lets the household skip income verification and qualify for the top tier.
Do I file once for all my children?
No. OkTAP takes one application per student, each with that student's own EVN.
What if someone other than a parent applies?
A non-parent or legal guardian applicant needs the Parental Consent Form (Form 591-F), and some applicants are asked for an IRS Form 1040.
Can I fix things after I'm approved?
School changes and tuition adjustments are accepted through December 31 of that application year, but a withdrawn application can't be reopened or resubmitted.
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 A withdrawn application can't be reopened.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. |
What is the next step?
Take the two-minute funding check. A tuition counselor will confirm your credit tier, any LNH or Catholic aid, and the dates you need to hit.
