Please elaborate on what needs to be corrected. Does the Form CSA-1099-R (or perhaps several Forms CSA-1099-R if multiple years are involved) issued by OPM not reflect the total of the distributions that you received? If the total reported by OPM on Forms CSA-1099-R does not reflect the correct total, you would need to contact OPM to obtain a corrected form.
When your OPM annuity starts, OPM will have you on interim status and pay an estimated benefit until they get everything processed to determine your actual monthly benefit. Once they have everything worked out they adjust your monthly benefit temporarily to make up for any difference in the payments made while you were on interim status. In the end the Forms CSA-1099-R report the total that was actually paid and that's what you report on your tax return.
This is opm disability pension. After start of SSDI my OPM added overpayment amount to be repaid. I paid taxes on the overpayment amount for year it was received. Now the amount deducted is included in my OPM Gross and I pay tax on that amount again. Hope I am explaining this correctly
Are you saying that in 2022 the amount of your OPM pension benefit for 2022 was reduced by the amount of the overpayment? If so, I would expect that your 2022 CSA-1099-R would show only the reduced amount you actually received and you would not be paying taxes twice on the same money. Do you already have your 2022 CSA-1099-R that shows a higher taxable amount than you actually received?
I think this falls under a "CLAIM OF RIGHT REPAYMENT" Anyone heard of this?
