We don't know if you are owed back pay for any year.  

• That is something for you to work out with your employer.
• It certainly would be worth asking the question.

From a tax point of view.  You should not have to change the 2025 tax return that you filed in 2026.

• If you were paid back pay this year (2026) for work you did this year (2026) it will go on your tax return next year (filed in 2027)..
• The IRS taxes income in the year it is received.
• Payments paid in 2026 for work done in 2025 is also reported on your 2026 tax return (filed in 2027.
