Hello! I am repaying a 2023 signing bonus of $35,000 this month ( Feb 2024), of which around $15,000 was taxes. I have yet to do my 2023 taxes and my former employer will not issue a corrected W2 for 2023. Can I deduct the $35000 from my 2023 income since I have yet to file those taxes or do I have to wait until I file my 2024 taxes to claim a tax credit?
