Yes, Social Security spousal benefits do increase with the COLA, and the adjustment happens automatically without any application or paperwork on your part. For 2026, the cost-of-living adjustment is 2.8 percent, and it applies to spousal payments the same way it applies to retirement and disability checks.1Social Security Administration. Cost-Of-Living Adjustment (COLA) The dollar amount you actually gain depends on the size of your current benefit, which is set by when you claimed and by any deductions coming out of your payment.
Why Spousal Benefits Rise Automatically
Federal law requires Social Security to raise the primary insurance amount (PIA) whenever inflation triggers an adjustment.2Office of the Law Revision Counsel. 42 USC 415 – Computation of Primary Insurance Amount The PIA is the base figure used to calculate the worker’s retirement benefit, and your spousal benefit is a percentage of that same figure. When the PIA goes up, the calculation that produces your check runs again on the new, higher number.
This applies whether you are a current spouse, a divorced spouse still eligible on a former partner’s record, or a surviving spouse. You do not need to file anything, call the agency, or confirm the increase. It appears in your payment on its own.
A Note for Former Government Employees
Until recently, the Government Pension Offset reduced or wiped out spousal benefits for people who also collected a pension from work not covered by Social Security. The Social Security Fairness Act, signed on January 5, 2025, eliminated the GPO for benefits payable after December 2023.3Social Security Administration. Social Security Fairness Act: Windfall Elimination Provision (WEP) and Government Pension Offset (GPO) If your spousal benefit was previously reduced by GPO, it should now be calculated without the offset and adjusted for COLA on the full amount.
How the Increase Reaches Your Check
The COLA is applied to the worker’s PIA first. Social Security then recalculates the spousal payment based on the new PIA. Because the spousal benefit can be as much as 50 percent of the worker’s PIA, the dollar gain for the spouse is roughly proportional to the worker’s gain.4Social Security Administration. Benefits for Spouses
A quick example with the 2026 COLA of 2.8 percent. Suppose the worker’s PIA is $2,000. After the adjustment, it becomes $2,056. A spouse collecting the full 50 percent would move from $1,000 to $1,028 a month.
Do not expect the math to line up perfectly with the announced percentage. Social Security rounds down to the next lower multiple of $0.10 at each step of the calculation.5Social Security Administration. Application of COLA to a Retirement Benefit Combined with any Medicare premium deducted from your payment, the deposit that shows up in your bank account can differ slightly from a straight 2.8 percent bump.
When You Will See the Higher Payment
The COLA announcement comes in mid-October, once the September inflation data is available. Social Security announced the 2.8 percent figure for 2026 on October 24, 2025, covering roughly 75 million people. In December, the agency sends notices through the My Social Security online message center or by mail showing the new dollar figure.1Social Security Administration. Cost-Of-Living Adjustment (COLA)
The higher benefit is technically payable for December, but because Social Security pays a month behind, the first check that reflects the COLA arrives in January.6Social Security Administration. Cost-of-Living Adjustment (COLA) Information For the 2026 adjustment, that meant January 2026 was the first month with the new amount.
How Much You Gain Depends on Your Claiming Age
The percentage is the same for every beneficiary, but the dollar increase depends on the size of the benefit it is applied to. Because your claiming age permanently sets that benefit, it also sets the value of every future COLA you will ever receive.
If You Claimed at 62
Claiming spousal benefits at 62 permanently reduces your payment. For someone born in 1960 or later, whose full retirement age is 67, the reduction runs about 35 percent of the spousal amount.7Social Security Administration. Benefit Reduction for Early Retirement A benefit that would have been $1,000 at full retirement age is roughly $650 at 62. A 2.8 percent COLA adds about $18 to the $650 check, versus about $28 to the $1,000 check. The gap compounds every year.
Waiting Past Full Retirement Age Does Not Help
Delayed retirement credits do not apply to spousal benefits. The maximum spousal payment is 50 percent of the worker’s PIA, and you reach that maximum at your full retirement age. Waiting until 68, 69, or 70 will not raise it. If you are also entitled to your own retirement benefit, deemed filing rules generally require you to apply for both at the same time, so you cannot draw the spousal amount while letting your own benefit grow.8Social Security Administration. Filing Rules for Retirement and Spouses Benefits
What Can Shrink the Net Gain
Medicare Part B Premiums
Most beneficiaries have their Medicare Part B premium deducted directly from their Social Security check. The standard Part B premium for 2026 is $202.90 a month, up $17.90 from the year before.9Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles When premiums and the COLA rise in the same year, the premium hike eats into the raise, so the net deposit grows by less than 2.8 percent.
A federal rule known as “hold harmless” keeps a Part B premium increase from actually cutting your net Social Security payment below the prior month’s amount.10Office of the Law Revision Counsel. 42 USC 1395r – Amount of Premiums for Individuals Enrolled Under This Part Your check can stay flat, but it cannot shrink because of a Part B increase. This shield only works if your Part B premium comes out of your Social Security payment. It does not apply in your first year of Medicare enrollment, when a state Medicaid program pays your premium, or when you owe higher income-related premiums (IRMAA).
Federal Income Taxes
A COLA raises your gross Social Security income, and that can push more of your benefit into the taxable range. The federal tax thresholds are based on “combined income,” which is your adjusted gross income plus any nontaxable interest plus half of your Social Security benefits. These thresholds have not been indexed to inflation since they were written into law in 1993.
For a married couple filing jointly:
- Below $32,000 in combined income, benefits are not taxed.
- Between $32,000 and $44,000, up to 50 percent of benefits may be taxable.
- Above $44,000, up to 85 percent may be taxable.
For single filers, the two thresholds are $25,000 and $34,000.11Office of the Law Revision Counsel. 26 USC 86 – Social Security and Tier 1 Railroad Retirement Benefits Because the dollar amounts are fixed, each year’s COLA can nudge someone across a line and increase the taxable portion of their benefit. If your combined income sits near one of these thresholds, review your withholding or estimated tax payments after the October COLA announcement.
