SSDI recipients receive their COLA in December, but the exact timing depends on your birth date and payment schedule

If you receive Social Security Disability Insurance (SSDI), your cost of living adjustment (COLA) payment arrives in December of the year it is announced. The Social Security Administration calculates the COLA each October based on inflation data, then distributes the increase starting in December. However, not everyone receives it on the same day — your payment date depends on which of three payment schedules you fall into, determined by your birth date.

The three SSDI payment schedules are: beneficiaries born on the 1st through the 10th of any month receive payments on the second Wednesday of each month; those born on the 11th through the 20th receive payments on the third Wednesday; and those born on the 21st through the 31st receive payments on the fourth Wednesday. Your December COLA payment follows this same schedule. If you were born on the 15th, for example, you would receive your COLA-adjusted payment on the third Wednesday of December, not on a fixed date.

Key Takeaways

  • Your December COLA payment arrives on your regular payment date, which is determined by your birth date and falls on the second, third, or fourth Wednesday of the month.
  • The COLA percentage is announced in October each year, and the increase takes effect with your December payment.
  • If you receive both SSDI and Supplemental Security Income (SSI), you may have different payment dates for each program.
  • You do not need to do anything to receive your COLA — it is applied automatically to your account once it is announced.

How to find your specific SSDI payment date

Your payment date is fixed and does not change from month to month. To confirm which Wednesday in December you will receive your COLA payment, log into your my Social Security account at ssa.gov. Under "Benefit Verification," you will see your payment date listed. You can also call the Social Security Administration at 1-800-772-1213 (TTY 1-800-325-0778) and ask a representative to confirm your payment schedule.

If you receive direct deposit, the payment will land in your bank account on your scheduled date. If you receive a paper check, it will arrive a few days after your payment date. If you use a Social Security payment card (a debit card issued by the SSA), the funds will be loaded on your scheduled date.

What happens if December 25th or 26th falls on your payment date

When a holiday falls on a scheduled payment date, the Social Security Administration pays you one business day early. If your payment date is the fourth Wednesday of December and that falls on December 25th (Christmas), you will receive your payment on December 24th instead. The same rule applies if your payment date lands on December 26th (the day after Christmas) — you receive it on December 24th.

This early payment includes your regular SSDI benefit plus your COLA increase. You do not receive a separate COLA payment; the increase is straightforward added to your normal monthly benefit amount starting in December.

How much your COLA payment will increase

The COLA percentage varies each year based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). In recent years, COLA increases have ranged from 0% to over 8%, depending on inflation. The Social Security Administration announces the exact percentage in October, so you will know the increase amount before your December payment arrives.

To calculate your new monthly benefit, multiply your current monthly SSDI payment by the COLA percentage announced that year. For example, if you receive $1,200 per month and the COLA is 3%, your new monthly benefit will be $1,236. This new amount will appear in your December payment and continue for all future months unless the COLA changes again the following year.

COLA payments if you also receive SSI

If you receive both SSDI and Supplemental Security Income (SSI), you have two separate payment schedules. Your SSDI payment follows the birth-date schedule described above, while your SSI payment is typically made on the first, second, or third of each month. Both payments will include their respective COLA increases in December, but they may arrive on different dates.

Check your my Social Security account to see both payment dates listed separately. If you have questions about which payment is which, call 1-800-772-1213 and ask the representative to clarify your two schedules.

What to do if your December payment does not arrive on time

If your payment does not arrive by the day after your scheduled payment date, contact the Social Security Administration when ready. Call 1-800-772-1213 or visit your local Social Security office. Have your Social Security number and bank account information ready. The representative can check whether the payment was processed and, if there was a delay, help you file a claim for the missing funds.

If you receive a paper check and it does not arrive within five business days of your payment date, report it as lost or stolen. The SSA can issue a replacement check or arrange for a direct deposit instead. If you use a payment card and the funds do not appear, contact the card issuer's customer service line (the number is on the back of your card) before calling Social Security, as the delay may be on the card company's end.

Frequently Asked Questions

Do I have to do anything to get my COLA payment in December?

No. The COLA is applied automatically to your SSDI account once it is announced in October. You do not need to contact Social Security, fill out any forms, or take any action. The increase will straightforward appear in your December payment.

What if I was not receiving SSDI in October when the COLA was announced?

If you began receiving SSDI after October but before December, you will still receive the COLA increase in your first payment. The increase is applied to all SSDI beneficiaries regardless of when they started receiving benefits that year.

Can I receive my COLA payment early or on a different date?

No. Your payment date is determined by your birth date and cannot be changed. The only exception is when a holiday falls on your scheduled payment date, in which case you receive it one business day early.

Will my COLA increase affect my other benefits or taxes?

The COLA increase may affect your taxes if your total income crosses certain thresholds, and it may affect means-tested programs like Medicaid or food information. Consult a tax professional or your state benefits office to understand how the increase affects your specific situation.
