Claim of Right Tax Credit (signing bonus clawback)
I received signing bonus (over $10k) in 2020. Then I left the employer and had to repay the amount.
I've read several discussions regarding the claim of right tax credit, but still haven't figured it out exactly.
Let's say I received $20k. Then I paid back the net amount I received ($20k - federal tax, social, medicare, state) last year (2021).
I received the bonus repayment letter from the previous employer and it also stated that I paid back the net amount.
I am doing tax return for the year of 2021 - I am trying to follow this instruction: "calculate the amount of tax you overpaid and take a refundable credit." Do I need deduct the total amount of the bonus ($20k) from 2020 year's total income then calculate the tax difference? Or do I need to deduct the net amount I paid back from 2020 year's total income then calculate the tax difference?
If I am wrong in both way, please let me know the right way to do this.
Thank you!
