SSI is supplemental security income. I have the computer-generated annuity estimate print out from the my work. It is shown me the amount of what I get after retire But the problem is I do not know the deductions(taxes, health, etc.) and that two (annuity and FERS Retirement supplement). FERS (Retirement supplement) is the SSI ? I think so but I'm also get the TSP. I'm 57 and been working for USPS for 34 years. So, the SSI is nothing to worry about taxes? TSP ,did you know what stand for? Thrift Saving Plan. That I get benefit payment too. So I when I retire, I get those three and little bit supplement from Union. So those two that I don't know what amount of and don't know what deductions amount is.
