Social Security was first subject to federal income tax in 1984. The combined income thresholds have never been adjusted for inflation, but benefit payments tend to increase each year due to wage growth and cost-of-living adjustments (COLAs). Consequently, a far greater percentage of beneficiaries owe tax on Social Security today versus when the law took effect 40 years ago.
Importantly, retirees that owe tax on Social Security income must make quarterly estimated payments to the Internal Revenue Service (IRS). Alternatively, retirees can request that a portion of their benefits be withheld by submitting a Form W-4V to their local Social Security office by mail or fax.
