Is it true that no taxpayer has all of their Social Security benefits taxed regardless of income?

The statement that no taxpayer has all of their Social Security benefits taxed regardless of income is true. Taxation of Social Security benefits depends on the taxpayer's income level, specifically their combined income.

When a taxpayer's combined income exceeds certain thresholds, a portion of their benefits may become taxable. However, it's important to note that a certain portion of individuals may not have to pay federal taxes on their Social Security benefits at all, particularly those whose combined income is below a specified limit. This means that there are taxpayers who may qualify for having some or all of their benefits remain untaxed based on their overall income situation, age, and filing status.

Thus, while some individuals who earn above the thresholds may have a portion of their benefits taxed, there are others who may not be subject to any taxation on their Social Security benefits, fitting the statement's description.
