For 2026, Social Security's cost-of-living adjustment (COLA) is 2.8%. Retirement planning should focus on the net benefit after Medicare, work-related withholding, savings limits, and possible federal taxes. The Social Security Administration based the adjustment on CPI-W growth from the third quarter of 2024 through the third quarter of 2025. It affects about 75 million Americans, with Social Security increases beginning in January 2026 and SSI increases paid December 31, 2025.

How much will the COLA add?
The social Security Administration estimates that the average retired-worker benefit rises from $2,015 to $2,071 per month. That is a $56 monthly increase, although each person's result depends on their earnings record, according to the agency's 2026 COLA fact sheet. The gross increase is not necessarily the increase deposited into a bank account. Medicare premiums and other deductions can reduce the amount received.
The standard Medicare Part B premium rises by $17.90 to $202.90 per month in 2026. That increase absorbs about 32% of the estimated $56 average COLA before other costs. The Part B deductible also rises to $283, according to the Centers for Medicare & Medicaid Services. Compare four figures when the January payment arrives: the old gross benefit, new gross benefit, Medicare deduction, and net deposit. This separates the COLA from changes elsewhere in the payment.
Will working reduce Social Security benefits?
Social Security's earnings test can reduce current benefits for workers below full retirement age. The 2026 earnings limit is $24,480, with $1 withheld for every $2 earned above the limit. For example, earnings of $30,480 are $6,000 over the limit.
Applying the stated formula would result in $3,000 of benefits being withheld. People who are at full retirement age for all of 2026 may keep their benefits regardless of earnings. Before changing work hours, ask whether the earnings test applies to you and calculate the possible withholding separately from income taxes.
How much can you save in workplace plans?
The 2026 employee contribution limit is $24,500 for most 401(k), 403(b), governmental 457, and Thrift savings plans. The general catch-up contribution for participants age 50 or older is $8,000, according to the IRS retirement-plan limit announcement. Where a plan permits it, participants ages 60 through 63 have an $11,250 catch-up limit.

That produces potential employee deferrals of $32,500 with the general catch-up or $35,750 with the higher catch-up. Ask the plan administrator which catch-up applies and whether payroll deductions are on pace to reach the intended amount. A higher legal limit does not automatically increase contributions.
What are the 2026 IRA limits?
The combined limit for traditional and Roth IRA contributions is $7,500 in 2026. It is $8,600 for people age 50 or older, but contributions cannot exceed the person's taxable compensation for the year. "Combined" matters: someone contributing $5,000 to a traditional IRA would have no more than $2,500 remaining for a Roth IRA under the general limit. The limits do not provide a separate $7,500 allowance for each IRA type.
Income can also affect the tax result. For a single taxpayer covered by a workplace plan, the traditional IRA deduction phases out between $81,000 and $91,000 of modified adjusted gross income. Roth IRA eligibility for single and head-of-household filers phases out between $153,000 and $168,000. These examples do not cover every filing status, so verify the rule that matches your return.
Could the COLA increase federal taxes?
The COLA increases gross Social Security income, which can affect how much of the benefit is taxable. Under current IRS guidance, up to 85% of benefits may be taxable when half of Social Security benefits plus other income exceeds $34,000 for a single filer or $44,000 for joint filers, as explained in IRS Publication 915. This does not mean the government applies an 85% tax rate. It means up to 85% of the benefits may be included in taxable income and then taxed under the applicable rules.
For 2026 tax planning, the standard deduction is $16,100 for single or married-separate filers, $24,150 for heads of household, and $32,200 for joint filers. These amounts generally affect returns filed in 2027. Before taking an IRA withdrawal or realizing other income, estimate half of annual Social Security benefits plus other expected income. Then compare the result with the relevant Social Security taxation threshold.
