"Financial Planning: Is Social Security Now Tax-Free?
One of the major topics surrounding the One Big Beautiful Bill (OBBB) was the taxation of Social Security. Now that the bill has been signed into law, we know that the method used to tax Social Security remains unchanged- but many seniors will still see their overall tax liability go down.
Most states, including California, do not tax Social Security. Federally, between 0% and 85% of benefits are reportable as income, meaning at least 15% is always tax-free. The taxable portion is based on a retiree's combined income, which includes adjusted gross income, tax-exempt interest, and half of their Social Security benefits. This formula was not changed by the OBBB. However, the standard deduction is increasing substantially, which reduces taxable income and in turn, lowers overall tax liability. Prior to the bill’s passage, a married couple aged 65 or older would have had a standard deduction of $33,200 in 2025 ($30,000 plus $3,200 for age). Starting in tax year 2025, that deduction can be as high as $46,700- a $13,500 increase. This results from a $1,500 increase to the base deduction for all filers, plus an additional $6,000 per person for those over age 65. Importantly, this extra $6,000 per senior (up to $12,000 per couple) is not technically part of the standard deduction- it is an above-the-line deduction that can be claimed even by those who itemize. This add-on begins to phase out when Modified Adjusted Gross Income exceeds $150,000 and is fully phased out above $250,000.
As a result, taxpayers in the 10%, 12%, and 22% brackets are most likely to benefit. So, while Social Security is still taxable, more of that income may now be shielded from taxes due to the expanded deductions. Additionally, the bill prevents the federal tax brackets from reverting to higher 2017 levels in 2026. The brackets will now remain at 10%, 12%, 22%, 24%, 32%, 35%, and 37%, instead of increasing to 10%, 15%, 25%, 28%, 33%, 35%, and 39.6%. For retirees with taxable Social Security or other ordinary income, this means lower effective tax rates moving forward. In short, Social Security is still taxable- but seniors will likely pay less, or even nothing, thanks to these changes."
