Who files this form
Use Form 564 to claim the 2025 Oklahoma Credit for Employees in the Aerospace Sector or an unused credit carried over from an earlier year.
To qualify, you must:
- Be employed in Oklahoma by, or contracting in Oklahoma with, a qualified employer on or after January 1, 2009, regardless of your hire date. The employer’s principal business activity must involve the aerospace sector.
- Have an undergraduate or graduate degree from a qualified engineering program, or hold a Professional Engineer license from the Oklahoma State Board of Licensure for Professional Engineers and Land Surveyors.
The definition also includes qualifying degree holders employed by professional staffing companies and assigned to Oklahoma’s aerospace sector, and people who worked in the sector, but not as full-time engineers, before earning their qualifying degree.
The credit is $5,000 per year for up to five years.

- Carrying credits too long or out of order: Unused credits may be carried over, in order, for no more than five years from when each credit was originally established.
- Leaving out carryover years: Enter the tax years when the unused credits were originally established, and complete Form 564 for each carryover year.
- Not transferring the total: Enter Part 3, line 3, on Form 511-CR.
Questions people ask
How much is the credit?
A qualified employee may claim $5,000 per year for up to five years.
Can I qualify with a Professional Engineer license instead of a degree?
Yes. The qualified employee definition allows either a degree from a qualified program or a Professional Engineer license from the Oklahoma State Board of Licensure for Professional Engineers and Land Surveyors.
What happens if the credit is more than my tax liability?
You may carry over unused credit for up to five years from when it was originally established. Use carryovers in order and complete Form 564 for each carryover year.
Can I still qualify if I change employers?
Beginning January 1, 2024, the qualified employee definition includes people who previously qualified and change employers, as well as first-time claimants who later change employers, provided they have not already claimed the lifetime maximum of five years. You must still meet the qualified employee requirements.
