The 2026 COLA will increase SSDI payments by a percentage set by Social Security in October 2025

Social Security announces the Cost of Living Adjustment (COLA) each October, and that percentage takes effect the following January. For 2026, the exact increase will not be known until October 2025, when Social Security calculates it based on inflation data from the third quarter of the year. The COLA is never may provide to be any specific amount — it depends entirely on whether prices rose or fell during that period.

When the 2026 COLA is announced, your new monthly SSDI payment will be calculated automatically. You will not need to do anything. Social Security will mail you a notice showing your old payment amount, the COLA percentage, and your new payment starting in January 2026. If you receive your payment by direct deposit, the new amount will straightforward appear in your bank account on your regular payment date in January.

The COLA affects everyone on SSDI the same way — it is a single percentage increase applied to all beneficiaries. A person receiving $1,200 per month and a person receiving $1,500 per month both receive the same percentage bump, so the dollar increase is larger for those with higher payments.

Key Takeaways

  • Social Security announces the 2026 COLA percentage in October 2025, and it takes effect on January 1, 2026.
  • The COLA amount is based on inflation data and is not set in advance — it could be zero, small, or larger depending on economic conditions.
  • Your payment increases automatically; you do not need to contact Social Security or take any action.
  • You will receive a notice in the mail before January showing your old payment, the COLA percentage, and your new amount.
  • The COLA applies to your primary SSDI payment only, not to any other benefits you may receive.

How the COLA percentage is calculated

Social Security uses the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) to measure inflation. Specifically, it compares the average CPI-W for July, August, and September of the current year to the same three months of the previous year. If prices went up, the percentage increase becomes the COLA. If prices stayed flat or fell, the COLA is zero — there is no negative COLA that would reduce your payment.

This method means the COLA reflects what actually happened to prices in the months leading up to the announcement, not a prediction or estimate. In years when inflation was high (such as 2022), the COLA was large. In years when inflation was low or prices fell, the COLA was small or zero. The calculation is done by the Department of Labor, and Social Security uses that official figure.

You cannot influence the COLA, and neither can Congress or Social Security. It is a mathematical result of the inflation measure. This is why the amount changes year to year and why no one can promise you what 2026 will bring.

When you will find out the 2026 COLA amount

Social Security announces the COLA on the second Thursday of October each year. For 2026, that announcement will happen in October 2025. The announcement is public — it appears on the Social Security website, in news reports, and in the notice Social Security mails to you.

After the announcement, you will have several months before the increase takes effect. Your notice will arrive in December 2025, showing the new payment amount that will start January 1, 2026. This gives you time to plan and adjust your budget if the increase is significant.

If you want to know the 2026 COLA as soon as it is announced, you can check the Social Security website (ssa.gov) on the announcement day, call Social Security's toll-free number at 1-800-772-1213, or wait for your notice to arrive in the mail.

How the 2026 COLA affects your benefits and taxes

The COLA increases your primary SSDI payment amount. If you have a spouse or child also receiving benefits on your record, their payments increase by the same percentage. However, there is a family maximum — the total amount Social Security will pay to all family members on one record. If your family is at the maximum, an increase to your payment may not result in an increase to other family members' payments, because the total cannot exceed the maximum.

The COLA can also affect whether you owe federal income tax on your SSDI benefits. SSDI itself is not taxable, but if you have other income (wages, interest, pensions), the COLA increase might push your combined income over the threshold where SSDI becomes partially taxable. The thresholds are $25,000 for a single filer and $32,000 for married filing jointly. If you are close to these amounts, the COLA increase could change your tax situation.

The COLA does not affect your Medicare premiums directly, but it can affect your out-of-pocket costs. If you pay a Part B or Part D premium, Social Security holds you harmless — meaning your SSDI payment cannot decrease because of a premium increase. However, if your COLA increase is larger than the premium increase, you keep the difference.

What to do if you do not receive a notice or your payment does not increase

Social Security mails COLA notices to all SSDI beneficiaries in December. If you do not receive yours by mid-January 2026, contact Social Security at 1-800-772-1213 to request a replacement. Have your Social Security number ready.

If your payment does not increase in January 2026 when the COLA takes effect, check your notice first to see if there is an explanation. Some beneficiaries do not receive a COLA increase if they are subject to the Government Pension Offset or Windfall Elimination Provision, though these rules are complex and rare. If your notice does not explain the situation, call Social Security to ask why your payment did not change.

Do not assume an error has occurred when ready. Sometimes the payment system takes a few days to process the change, and you may see the increase on your second payment of the month rather than the first. If the increase does not appear within two weeks of the normal COLA effective date, contact Social Security.

Planning your budget around the 2026 COLA

The COLA increase is real money, but it is usually modest. Recent COLAs have ranged from zero to 8.7 percent. Even a 5 percent increase on a $1,200 payment is only $60 per month — helpful, but not transformative. Plan for the increase to cover inflation rather than to create new spending room.

If you have debt, medical expenses, or other financial obligations, consider using the increase to build a small emergency fund or reduce what you owe. If your SSDI payment is your only income, the COLA is designed to keep your purchasing power steady, not to improve it.

If you receive Supplemental Security Income (SSI) in addition to SSDI, the SSI payment also receives a COLA increase, and it takes effect on the same date. However, SSI has a resource limit ($2,000 for an individual), so if the increase pushes your total resources over that limit, it could affect your SSI may be able to access. This is rare, but worth checking if you are close to the limit.

Frequently Asked Questions

Can I find out the 2026 COLA before October 2025?

No. The COLA is calculated from actual inflation data from July through September 2025, so it cannot be known until that data is complete and processed. Anyone claiming to know the 2026 COLA before October 2025 is guessing. You can look at recent COLA history to see the range of past increases, but that does not predict 2026.

What if I disagree with the COLA amount announced?

The COLA is a mathematical calculation based on the Consumer Price Index, which is set by the Department of Labor. Social Security does not have discretion to change it. If you believe the inflation measure itself is wrong, that is a policy question for Congress, not something you can dispute with Social Security. Your individual COLA amount cannot be negotiated or appealed.

Does the COLA explore if I am working and earning wages?

Yes. The COLA increases your primary SSDI payment regardless of whether you work. However, if you earn above the annual earnings limit (which changes each year), Social Security will withhold part of your payment. The COLA increase does not change how the earnings limit works.

Will the 2026 COLA be higher or lower than 2025?

That depends on inflation between July and September 2025. If prices rise faster than they did in 2024, the COLA could be higher. If inflation slows, it could be lower. No one can predict this in advance. Social Security will announce the actual figure in October 2025.

What happens to my COLA if I reach full retirement age while on SSDI?

When you reach full retirement age, your SSDI payment converts to a retirement benefit, but the amount does not change. You continue to receive COLA increases each January for the rest of your life. The COLA applies to retirement benefits the same way it applies to SSDI.
