Which type of income is most likely to affect the taxability of Social Security benefits?

Investment income is most likely to affect the taxability of Social Security benefits due to the income thresholds established by the Internal Revenue Service (IRS). Social Security benefits are subject to taxation based on the taxpayer’s combined income, which includes adjusted gross income (AGI) along with any nontaxable interest and half of the Social Security benefits received. When a taxpayer's combined income exceeds certain limits, a portion of their Social Security benefits becomes taxable. Investment income, such as dividends, interest, and capital gains, contributes to this combined income calculation. If a taxpayer has a substantial amount of investment income, it could increase their total income to the point where more of their Social Security benefits are taxable. In contrast, other forms of income like unemployment benefits and self-employment income also affect overall income, but they do not have the same specific impact on the taxation of Social Security benefits as investment income does, given the calculation of combined income. Tax-exempt interest income is excluded from the taxable calculation, which means it won't increase the portion of Social Security benefits that are taxable. Thus, it is the investment income that holds the most influence regarding the taxability of Social Security benefits.
