SSI (Supplemental Security Income) is frequently confused with SSDI (Social Security Disability Income). SSI is welfare and is never taxable. SSDI is treated just like Social Security Retirement Income: i.e. it may become partially taxable only when added to your other income.
Most (almost all) SSDI recipients do not normally need to file a tax return nor get any benefit from doing so. If SSDI is your ONLY income then you do not need to file a tax return unless you have health insurance thru the ACA Marketplace and will not owe any income taxes.
