Retirees in South Carolina are poised to benefit from a sweeping federal tax reform aimed at preserving more of their income.
Under the newly passed One Big Beautiful Bill, a senior tax deduction will dramatically reduce—if not eliminate—federal taxes on Social Security income for most older Americans.
In South Carolina, 1 million retirees are expected to qualify.
Most Seniors Will Pay No Tax on Social Security
Starting in the 2026 tax year, 88% of seniors nationwide will owe nothing in federal taxes on their Social Security income, according to the White House. That’s up from just 64% today and translates to 14.2 million more retirees keeping their full benefit checks.
This change is driven by a new senior deduction of $6,000 for individuals and $12,000 for married couples, layered on top of existing standard and senior deductions.
In total, deductions could reach $23,750 for individual filers and $46,700 for joint filers over 65.
South Carolina’s Aging Population Set to Gain
South Carolina is home to 5.37 million people, with 1.05 million residents aged 65 and older—accounting for 19.3% of the state’s population, according to the most recent census data. That demographic shift puts the Palmetto State well above the national average and highlights the bill’s local impact.
An estimated 1 million South Carolina seniors will qualify for the Social Security tax exemption provided by the new law. In addition to the deduction, the state is projected to see real wage increases of $3,300 to $6,000 and take-home pay boosts up to $9,800—offering modest but meaningful relief to senior households still in the workforce.
Who Benefits—and Who Doesn’t
The senior tax deduction will help many retirees, but not all. The biggest beneficiaries will be middle-income seniors who still owe income taxes each year. These households may see their taxable income fall below the new threshold, effectively erasing any tax burden on Social Security.
But those already living on limited means may not benefit at all. Retirees with little or no taxable income—often those relying solely on Social Security—already pay no tax and won’t see a change. Similarly, the deduction phases out for individuals earning more than $75,000 and couples above $150,000, with full phase-out at $175,000 and $250,000.
And while the deduction is currently authorized through 2028, it is not permanent. Congress would need to extend or renew the policy beyond that year.
A Boost for Homeowners Facing Rising Costs
South Carolina’s affordability has attracted retirees for years, but the cost of aging in place is rising fast. Homeowners are dealing with increasing property taxes, homeowner’s insurance, and utilities—all of which can stretch retirement budgets.
The expanded SALT deduction cap—rising from $10,000 to $40,000—offers added relief for those in high-tax counties. When paired with the senior deduction, these changes could help homeowners stay in their properties longer and age in place more affordably. The timing also aligns with a potential Social Security COLA increase in 2026, giving fixed-income households a little more room to maneuver.
