Yes to both questions - the IRS can garnish Social Security and you need to file if you have income, including Social Security.
Hope that helps.

No, not your SSI. They can levy on other social security payments or other assets, but not SSI (prohibited by 42 USC 407). You do not have to file a tax return if SSI is your only income because SSI is not taxable.

IRS publication 915 talks about the taxation of social security benefits, and points out that SSI is not taxable.

No to both. The IRS cannot garnish SSI checks, and the income is not taxable. Supplemental Security Income (SSI) is different from Social Security Disability Benefits (SSD). SSI is a need-based program designed for people who cannot afford to make ends meet, can't work due to a disability, and haven't earned enough Social Security Credits to qualify for regular Social Security Disability Benefits.
However, if what you are receiving is SSD income, which is not need-based, and only requires that you are disabled and have earned enough social security credits to qualify, then you would probably have to file tax returns, and the income is subject to garnishments.
