Senior Deduction — While there had been discussion of eliminating tax on Social Security, a compromise was to provide seniors over age 65 with a $6,000 addition to the standard deduction and the existing senior deduction ($2,000 single/$1,600 per qualifying married spouse). This added deduction is available for 2025 through 2028. The $6,000 deduction phases out at a rate of 6% of the excess amount for single persons with incomes over $75,000 and married couples with incomes over $150,000. The deduction is fully phased out for single persons with incomes over $175,000 and married couples with incomes over $250,000. A single senior with $60,000 of income would have a standard deduction of $15,750, the existing $2,000 senior deduction and an added $6,000, for a total deduction of $23,750. With the $6,000 added deduction, the majority of seniors will not pay tax on their Social Security. High-income seniors will continue to pay tax on 85% of their Social Security.
Susan Single. Assume Susan is age 78, has Social Security of $28,000 and other income for a total of $45,000. A single senior has a 2025 standard deduction of $15,750, existing senior deduction of $2,000 plus $6,000, for a total of $23,750. Because her income is over $25,000, part of her Social Security is tax-free and part is taxable. With her standard deduction, existing senior deduction, tax-free portion of Social Security and the added $6,000 Senior Deduction, Susan will pay zero federal income tax.
Helen Single. Assume Helen is age 82 and has Social Security of $36,000, a large IRA payout and other income for a total of $100,000. A single senior has a 2025 standard deduction of $15,750, an existing senior deduction of $2,000 plus the new Senior Deduction. However, Helen’s Senior Deduction is reduced because she has over $75,000 of income. Her Senior Deduction is reduced to $4,500, for a total of $22,250. Because her income is over $34,000, a larger portion of her Social Security is taxable. While her $4,500 Senior Deduction saves some tax, Helen is likely to pay over $5,000 in income tax.
Jim and Kate Married. Assume Jim is age 80 and Kate is age 78. They receive Social Security of $44,000 and other income for a total of $75,000. A married couple filing a joint return benefits from a 2025 standard deduction of $31,500, the existing $3,200 deduction for two seniors plus the new Senior Deduction of $12,000, for a total of $46,700. Because their income is over $32,000, part of the Social Security is tax-free and part is taxable. With their standard deduction, tax-free portion of Social Security and the added $12,000 Senior Deduction, Jim and Kate will pay zero federal income tax.
Joe and Alice Married. Assume Joe is age 84 and Alice is age 79. They receive Social Security of $64,000, a pension, two large IRA payouts and investment income for a total of $200,000. A married couple filing a joint return will benefit from a 2025 standard deduction of $31,500, an existing $3,200 senior deduction plus the new Senior Deduction. Because their income is over $150,000, each $6,000 Senior Deduction is reduced to $3,000. The standard and existing senior deduction plus the reduced Senior Deductions equal $40,700. Because their income is over $32,000, part of the Social Security is tax-free and part is taxable. With their standard deduction, tax-free portion of Social Security and the added $6,000 Senior Deduction, Joe and Alice are likely to pay over $11,000 in income tax.
