The final 2027 Social Security cost-of-living adjustment, or COLA, has not been set. The Social Security Administration says it will announce the percentage in October 2026, so earlier figures are projections. Several related 2027 limits also remain unsettled, including the taxable wage maximum and retirement earnings-test thresholds. For now, retirees and workers should use confirmed 2026 figures as reference points, not assume they will continue unchanged.

When will the 2027 COLA become official?
A cola is an annual benefit adjustment intended to reflect inflation. The final calculation depends on the change in the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W. SSA will compare the relevant third-quarter inflation figures and announce the result in October 2026.
Its current COLA summary confirms that the 2027 rate has not yet been determined. SSA's fiscal year 2027 budget justification assumes a 2.4% COLA beginning in January 2027 for SSI cost estimates. That is a budgeting assumption, not the official statutory calculation. As a simple illustration, 2.4% would add $48 to a $2,000 monthly benefit before Medicare deductions.
Which benefit and earnings limits are confirmed?
The confirmed 2026 COLA is 2.8%. It increased Social Security and Supplemental Security Income payments for 2026, according to the SSA's 2026 COLA fact sheet. The Social Security taxable maximum is $184,500 in 2026.
Employees and employers each pay the 6.2% Social Security payroll tax on covered earnings up to that amount. The 2027 wage base will be indexed to average wages but has not yet been published. People who collect retirement benefits before full retirement age should also watch the earnings test. The confirmed 2026 rules are: These rules can temporarily reduce current payments, so anyone planning work income in 2027 should wait for SSA's updated limits before setting an exact earnings target.
- Under full retirement age all year: $24,480 limit, with $1 withheld for every $2 earned above it.
- Reaching full retirement age during the year: $65,160 limit for earnings before the qualifying month, with $1 withheld for every $3 above it.
- At full retirement age: the earnings test no longer applies.
How could Medicare affect the increase?
A COLA raises the gross Social Security benefit, but many retirees judge the result by the net deposit after Medicare premiums. The Medicare trustees estimate a standard Part B premium of $209.50 per month for 2027, but that amount is not final. The hold-harmless provision generally protects about 70% of Part B enrollees whose premiums are deducted from Social Security.

For those beneficiaries, the premium increase generally cannot exceed the dollar amount of their Social Security benefit increase. That protection does not guarantee a larger net payment. A modest COLA could be partly or fully absorbed by a higher Part B premium. Retirees should compare both finalized amounts before treating the gross COLA as additional spending money.
Which policy changes may affect retirees?
The Social Security Fairness Act repealed the Windfall Elimination Provision and Government Pension Offset for benefits payable after December 2023. Those formulas had reduced benefits for some people receiving pensions from jobs not covered by Social Security. The repeal can raise payments for affected teachers, firefighters, police officers, certain federal employees, and others with non-covered pensions. SSA explains the affected groups and implementation on its Social Security Fairness Act page.
A separate tax provision gives eligible people age 65 or older an additional deduction of up to $6,000 per person through 2028. Qualifying joint filers may deduct up to $12,000. The deduction phases out above modified adjusted gross income of $75,000 for individuals and $150,000 for joint filers. It reduces taxable income; it does not increase the monthly Social Security check.
What should readers do before October?
Avoid building a 2027 budget around the 2.4% planning assumption. Instead, model several outcomes and keep Medicare costs separate from the gross benefit calculation.
A practical review should include: Longer-term financing remains a separate issue. The 2026 Social Security Trustees Report projects OASI trust-fund depletion in late 2032 without legislation, after which continuing income would cover 78% of scheduled retirement and survivor benefits. That projection signals a need for congressional action; it is not an announced 2027 benefit cut.
- Record the current gross Social Security benefit and Medicare deduction.
- Estimate 2027 income from work if benefits are being collected before full retirement age.
- Check whether a non-covered government pension previously triggered WEP or GPO.
- Review eligibility for the enhanced deduction if age 65 or older.
- Replace projections with SSA's official COLA and limits after the October announcement.
