Social Security recipients are set to receive higher monthly payments in 2027, but the increase may not translate into an equivalent gain in after-tax income. While the annual cost-of-living adjustment (COLA) is designed to help beneficiaries keep pace with inflation, the federal income thresholds used to determine whether Social Security benefits are taxable have remained unchanged for decades.
The Social Security Administration (SSA) has announced a 3.6% cost-of-living adjustment for 2027. The increase is expected to raise the average retired worker’s monthly benefit from $2,095 to approximately $2,170, providing an additional $75 per month. Over a full year, that amounts to roughly $900 in additional benefits.
Nearly 72 million Social Security beneficiaries are expected to receive higher payments beginning in January 2027. Supplemental Security Income (SSI) recipients will see increased payments starting December 31, 2026.
However, the adjustment comes with an important consideration for retirees who receive income from pensions, investments, retirement accounts, or other sources. Higher Social Security payments could increase the amount of benefits subject to federal income tax.
Benefits
The 2027 COLA is intended to help Social Security recipients maintain their purchasing power as the cost of everyday expenses changes.
Alongside the benefit increase, several other Social Security adjustments are expected to take effect in 2027.
The maximum amount of annual earnings subject to Social Security payroll taxes will increase from $184,500 to $192,300. The maximum monthly benefit for someone retiring at full retirement age will rise from $4,152 to $4,188.
SSI recipients will also receive higher federal payments. The monthly payment standard is expected to increase to $1,029 for an eligible individual and $1,544 for an eligible couple.
These adjustments affect different groups of beneficiaries and are calculated under separate rules. The COLA applies to Social Security benefits, while the taxable earnings limit determines how much employment income is subject to Social Security payroll taxes.
The SSA provides information about annual benefit adjustments and eligibility through its official COLA information page.
Thresholds
The federal government uses a calculation known as combined income, or provisional income, to determine whether Social Security benefits are subject to federal income tax.
The calculation generally includes adjusted gross income, tax-exempt interest, and half of a person’s annual Social Security benefits.
The applicable thresholds depend on filing status.
| Filing Status | First Threshold | Second Threshold |
|---|---|---|
| Single | $25,000 | $34,000 |
| Married Filing Jointly | $32,000 | $44,000 |
For single taxpayers, benefits generally are not taxable when combined income is $25,000 or less. Above that amount, up to 50% of benefits may become taxable. Once combined income exceeds $34,000, as much as 85% of benefits may be included in taxable income.
For married couples filing jointly, the corresponding thresholds are $32,000 and $44,000.
These limits were established through legislation passed in 1983 and 1993. The higher taxation tier took effect in 1994.
Unlike many other tax provisions, the thresholds have not been adjusted for inflation or wage growth. As a result, retirees may gradually cross the limits as their benefits and other income increase.
The IRS explains how Social Security benefits are taxed and provides guidance on determining whether benefits must be included in taxable income.
Taxes
The 2027 COLA could affect retirees whose combined income is already close to one of the existing tax thresholds.
Consider a retired worker receiving an additional $900 in annual Social Security benefits. Because half of those benefits are included in the combined income calculation, the increase could add approximately $450 to provisional income.
That change may be enough to push some retirees above a threshold, particularly if they also receive interest income, pension payments, or withdrawals from retirement accounts.
For example, a single retiree with combined income near $34,000 could move into the higher Social Security taxation range after accounting for the benefit adjustment and other income changes.
However, an 85% taxable-benefit threshold does not mean an individual pays an 85% tax rate.
Instead, it means that up to 85% of Social Security benefits may be included in taxable income. The actual federal income tax owed depends on the taxpayer’s applicable tax bracket and overall financial circumstances.
The distinction is important because the amount of benefits subject to tax and the tax rate applied to that income are two separate calculations.
Impact
The frozen thresholds have gradually increased the number of Social Security recipients who may owe federal income taxes on their benefits.
As benefit payments rise with inflation, more retirees can cross the existing income limits, even when their overall financial circumstances have not improved substantially.
The Congressional Budget Office estimates that slightly more than half of Social Security beneficiaries will owe federal income taxes on their benefits in 2026.
This trend creates an additional consideration for retirement planning. A COLA can increase monthly payments while also increasing the portion of benefits that may be subject to taxation.
Retirees with multiple income sources may be particularly affected. Pension payments, investment earnings, and withdrawals from traditional retirement accounts can all influence combined income.
Deduction
Some older taxpayers may qualify for additional federal tax relief.
Eligible taxpayers aged 65 and older can claim an additional $6,000 deduction for tax years 2025 through 2028. The deduction may reduce taxable income and, depending on individual circumstances, lower the amount of federal income tax owed.
However, it does not change the underlying Social Security taxation thresholds.
Eligibility requirements and income limitations may also affect the amount of the deduction available to an individual taxpayer.
Retirees should review their income sources and deductions when preparing their tax returns. The IRS provides information on tax benefits for older adults, including deductions and other provisions that may apply to retirement income.
Planning
The 2027 Social Security COLA is expected to provide additional income to millions of beneficiaries. However, the unchanged federal tax thresholds mean that the increase may not result in an equivalent improvement in after-tax income for everyone.
Retirees can evaluate the potential impact by reviewing their combined income, retirement account withdrawals, investment earnings, and tax withholding.
The SSA is expected to make individual COLA notices available through personal my Social Security accounts in late November, with notices also arriving by mail in December.
Know how the adjustment interacts with existing tax rules can help retirees prepare for the coming year. The benefit increase remains an important source of financial support, but its effect on household income will depend on each recipient’s broader financial circumstances.
