🆕 Update — October 14, 2026: The SSA has officially announced the 2027 Social Security COLA is 3.6%. Read our Social Security COLA 2027 Official Guide →
The Social Security COLA 2026 is 2.8%. The SSA announced this rate on October 24, 2025. Benefits increased with January 2026 payments (December 31, 2025 for SSI). The increase is applied automatically — you do not need to apply. Your actual net deposit may be smaller than the gross percentage because Medicare Part B premiums also rose in 2026.
We looked into the official SSA announcement, BLS CPI-W data, and CMS Medicare premium records to give you a complete, accurate breakdown of how the Social Security COLA 2026 works, what it means in dollar terms, and how it interacts with Medicare costs and federal taxes.

What Is the Social Security COLA for 2026?
The Social Security COLA 2026 is 2.8%. The Social Security Administration announced this figure on October 24, 2025, following the Bureau of Labor Statistics' release of the September 2025 Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) data, the final data point in the annual COLA calculation formula.
The 2026 COLA is higher than the 2025 rate of 2.5%, reflecting somewhat stronger inflation in the third quarter of 2025 compared to the prior year. The 2024 rate was 3.2%.
| Year | COLA Rate | Standard Part B Premium | Part B Increase |
|---|---|---|---|
| 2024 | 3.2% | $174.70 | +$9.80 |
| 2025 | 2.5% | $185.00 | +$10.30 |
| 2026 | 2.8% — Official | $202.90 | +$17.90 |

The Plain English Version
- The 2026 Social Security COLA is 2.8% — confirmed, official, and already in effect.
- It was announced October 24, 2025 and took effect with January 2026 benefit payments.
- The raise is applied automatically — you do not need to contact SSA or submit any form.
- The Medicare Part B standard premium also rose in 2026, which reduces the net deposit for most beneficiaries.
- Benefits are never reduced due to low inflation — the minimum COLA is always 0%.
How Much Will Social Security Benefits Increase in 2026?
The dollar amount of your 2026 COLA increase depends entirely on your current gross monthly benefit. The formula is straightforward: multiply your benefit by 2.8%.
| Current Monthly Benefit | 2026 COLA Increase (+2.8%) | New Monthly Benefit | Annual Increase |
|---|---|---|---|
| $800 | +$22.40 | $822.40 | +$268.80/yr |
| $1,200 | +$33.60 | $1,233.60 | +$403.20/yr |
| $1,500 | +$42.00 | $1,542.00 | +$504.00/yr |
| $1,900 | +$53.20 | $1,953.20 | +$638.40/yr |
| $2,500 | +$70.00 | $2,570.00 | +$840.00/yr |
| $3,000 | +$84.00 | $3,084.00 | +$1,008.00/yr |

When Does the 2026 COLA Take Effect?
The 2026 Social Security COLA took effect as follows:
- Social Security retirement, disability (SSDI), and survivor benefits: The increase applied starting with the December 2025 benefit, which was deposited in January 2026.
- Supplemental Security Income (SSI): Increased SSI payments began on December 31, 2025 — the last business day of the month — to reflect the January 2026 effective date.
You do not need to apply for the COLA increase. SSA applies it automatically. In December 2025, SSA mailed personalized COLA notices to all beneficiaries showing the new gross benefit amount, Medicare Part B deduction, and net monthly payment.

How Is the Social Security COLA Calculated?
The annual COLA is not a political decision or a congressional vote. It is an automatic calculation established under the Social Security Amendments of 1972, tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), published monthly by the Bureau of Labor Statistics.
The SSA compares the average CPI-W index value for July, August, and September of the current year to the average CPI-W for the same three months of the prior year (or the last year a positive COLA was approved). The percentage change between those two averages becomes the next year's COLA rate.
For the 2026 COLA: the third-quarter 2025 CPI-W average was compared to the third-quarter 2024 average. The result was a 2.8% increase, which SSA announced on October 24, 2025 after the September 2025 CPI-W data was released by BLS.
If the CPI-W shows zero or negative change, the COLA is set at 0%. Social Security benefits are never cut due to deflation.
How the 2026 COLA Affects Your Monthly Benefit
📖 Illustrative Example
This is a hypothetical example, not a real person.
Why the January Check Is Smaller Than the Announced COLA Percentage Suggests
Raymond received $2,800/month gross in 2025. His Medicare Part B premium of $185.00 was deducted directly, leaving a net deposit of $2,615/month. When the 2026 COLA of 2.8% was applied in January, his gross benefit increased by $78.40 to $2,878.40. But Medicare Part B also rose to $202.90, a $17.90/month increase. His net monthly deposit increased by $60.50 ($78.40 minus $17.90), not the full $78.40. Raymond's check still went up, but by less than the headline 2.8% figure implied.
- 2025 gross benefit: $2,800 | Part B: $185.00 | Net deposit: $2,615.00
- 2026 COLA gross increase (+2.8%): +$78.40/month
- 2026 Part B premium increase: +$17.90/month
- Net deposit increase: +$60.50/month
- New 2026 net monthly deposit: $2,675.50
Does the 2026 COLA Affect Medicare Costs?
The Social Security COLA does not determine Medicare Part B premiums — CMS sets them independently each year. In 2026, the standard monthly Part B premium rose to $202.90 (up $17.90 from $185.00 in 2025). The annual Part B deductible increased to $283 in 2026.
Because most Medicare-enrolled Social Security recipients have their Part B premium automatically deducted from their check, this $17.90 monthly increase directly reduces the net impact of the 2026 COLA increase on what you actually deposit.
The Hold Harmless Rule: What It Means for You
Federal law — specifically Section 1839(f) of the Social Security Act — includes the Hold Harmless rule. It ensures that if the Medicare Part B premium increase would reduce your net Social Security check below the prior year's level, the premium is capped so your check does not shrink.
In 2026, the Part B increase of $17.90 did not exceed the dollar value of the 2.8% COLA for most beneficiaries, so the Hold Harmless rule was not widely triggered. However, for beneficiaries with very low monthly benefits, the $17.90 Part B increase could exceed their COLA dollar increase — in those cases, Hold Harmless protects the net check.
Hold Harmless does not apply if you: are newly enrolled in Medicare Part B, pay Part B by quarterly bill rather than Social Security deduction, or are subject to IRMAA income-related premium surcharges.
Does the 2026 COLA Affect Taxes?
A higher Social Security benefit from the 2026 COLA can affect how much of your benefits are subject to federal income tax — depending on your total income.
The IRS uses a measure called Provisional Income (also called Combined Income): your adjusted gross income + non-taxable interest + 50% of your total Social Security benefit. The federal thresholds are fixed by law and do not adjust for inflation:
- Single filers: If Provisional Income exceeds $25,000, up to 50% of your Social Security may be taxable. Above $34,000, up to 85% may be taxable.
- Married filing jointly: Thresholds are $32,000 and $44,000.
Because these thresholds never adjust for inflation, a COLA increase can push some beneficiaries across a threshold for the first time. We recommend using our Retirement Tax Estimator ↗ after any COLA increase to recalculate your tax exposure.
To adjust federal withholding from your Social Security check, file Form W-4V (Voluntary Withholding Request) with the SSA. You can choose 7%, 10%, 12%, or 22% withholding.
What About SSI, SSDI, and Other Benefits?
The 2026 COLA of 2.8% applied to all Social Security programs, including:
- Supplemental Security Income (SSI): The federal SSI benefit increased by 2.8% in 2026. The maximum federal SSI payment for an individual rose to $994/month; for couples, to $1,491/month. SSI payments increased on December 31, 2025 (reflecting the January 2026 effective date).
- Social Security Disability Insurance (SSDI): SSDI benefits received the same 2.8% COLA increase as retirement and survivor benefits, effective January 2026.
- Veterans' benefits (VA): VA disability compensation and pension programs are adjusted by the same COLA rate as Social Security, under a separate federal provision. The 2.8% rate also applied to VA benefits beginning December 1, 2025 (paid January 1, 2026).
The maximum taxable earnings base for workers also adjusted in 2026: wages up to $184,500 are subject to Social Security payroll taxes, up from $176,100 in 2025.
Calculate Your Own Social Security COLA Increase
The 2026 COLA is a confirmed 2.8% — but your actual dollar increase depends on your own current monthly benefit. A $1,000 benefit gains $28/month. A $2,500 benefit gains $70/month. Those are very different numbers for your household budget.

Common Questions: Frequently Asked Questions
State-Level Tax Treatment of the 2026 COLA
Does Your State Tax the COLA Increase?
As of 2026, 42 states and the District of Columbia do not tax Social Security benefits — meaning your 2026 COLA increase is fully exempt at the state level. However, 8 states still tax some Social Security benefits in 2026: Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, and Vermont. Most of these 8 states exempt benefits below an income threshold. Check your state revenue department.
