If you searched for "social security price increase" because your check went up less than the announced 2.8% cost-of-living adjustment, you already found the problem: the Medicare Part B premium comes out of your check automatically, and it rose $17.90 a month for 2026, from $185.00 to $202.90, according to the Centers for Medicare and Medicaid Services. For anyone whose Social Security raise was small in dollar terms, that Part B increase can eat up a third, a half, or in rare cases nearly all of the announced raise before it ever reaches your bank account. This article walks through exactly why that happens, does the math on a real example, and covers the other deductions (IRMAA, tax withholding, overpayment recovery) that can shrink a Social Security check even in a year when benefits officially "went up."
For the raw 2026 COLA numbers by benefit type, see SSDI COLA 2026. This page focuses on the deduction side: what happens after the COLA is applied and before the money lands in your account.
The 2.8% raise is a gross number, not a net one
The Social Security Administration announced a 2.8% cost-of-living adjustment for 2026, effective for payments starting in January 2026, raising the average retirement benefit by about $56 a month, per the SSA's official announcement. That 2.8% is applied to your gross benefit amount, the number before any deductions.
But almost nobody actually receives their gross benefit. Most people enrolled in Medicare Part B have the premium deducted directly from their Social Security check before it's deposited. So the number that changes on your bank statement is:
New net check = (Old gross benefit x 1.028) - New Part B premium - any IRMAA surcharge - other withholdings
That last line is where the "price increase" search intent comes from. People see the news that benefits rose 2.8%, then look at their direct deposit and see a much smaller bump, sometimes as little as $20 or $30 more per month. Nothing was miscalculated. The COLA raised the gross amount correctly; Medicare simply took a larger bite out of it than the year before.
Medicare Part B premium for 2026: the main culprit
| Item | 2025 | 2026 | Change |
|---|
| Standard Part B monthly premium | $185.00 | $202.90 | +$17.90 |
| Part B annual deductible | $257 | $283 | +$26 |

A $17.90 monthly increase sounds small next to a $56 average COLA raise, but the COLA is a percentage applied to YOUR benefit, not the average. If your gross benefit is lower than average, your dollar increase from the COLA is also lower, and the Part B increase eats a bigger share of it.
Worked example
Say your gross SSDI benefit in 2025 was $1,600 a month.
- 2026 COLA raise: $1,600 x 2.8% = $44.80
- New gross benefit: $1,644.80
- Part B premium increase: -$17.90
- Net increase you actually see: about $26.90 a month, not $44.80
If your gross benefit was lower, say $1,100 a month, the math looks worse:
- 2026 COLA raise: $1,100 x 2.8% = $30.80
- Part B premium increase: -$17.90
- Net increase: about $12.90 a month
This is why the hold harmless rule exists, and why it matters whether it applies to you.
The hold harmless rule: who it protects, and why it won't help most people in 2026
Federal law includes a "hold harmless" provision that prevents the Medicare Part B premium increase from making your Social Security check go DOWN in dollar terms. It applies only if all of these are true:
- Your Part B premium is deducted directly from your Social Security check
- You do NOT pay an IRMAA surcharge (see below)
- You are not newly enrolling in Part B this year
- You are not dual-eligible for Medicaid (which pays your Part B premium for you)
For beneficiaries who qualify, the rule caps your Part B increase so that your net check cannot drop below last year's net check, even if the full premium increase would otherwise wipe out your COLA raise entirely.
For 2026, most people won't need this protection. The average dollar COLA increase (about $56) is larger than the Part B premium increase ($17.90), so most checks still rise in net terms. But the Nolo legal guide to the hold harmless rule notes that an estimated 4 million lower-income beneficiaries, people whose individual dollar COLA increase is smaller than $17.90, will have their premium increase capped under this rule so their check doesn't shrink.
If your gross benefit is low enough that 2.8% of it comes to less than $17.90 (that's any gross benefit under roughly $639 a month), hold harmless should prevent your net check from falling below its 2025 level. It does not guarantee your check will rise by the full 2.8%, only that it won't drop.
IRMAA: the other deduction, and it only applies to higher earners
If your modified adjusted gross income (MAGI) from your 2024 tax return was above certain thresholds, you pay an Income-Related Monthly Adjustment Amount (IRMAA) on top of the standard Part B premium. IRMAA is recalculated every year based on a two-year-old tax return, so a jump in income in 2024 (a Roth conversion, a big capital gain, a pension lump sum) can trigger a higher Part B and Part D premium in 2026 even if your income has since dropped.
| 2024 MAGI, single | 2024 MAGI, married filing jointly | Total monthly Part B premium 2026 |
|---|
| $109,000 or less | $218,000 or less | $202.90 (standard) |
| $109,000.01 to $137,000 | $218,000.01 to $274,000 | $284.10 |
| $137,000.01 to $171,000 | $274,000.01 to $342,000 | $405.90 |
| $171,000.01 to $205,000 | $342,000.01 to $410,000 | $527.70 |
| $205,000.01 to $499,999.99 | $410,000.01 to $749,999.99 | $649.50 |
| $500,000 or more | $750,000 or more | $689.90 |

If you're subject to IRMAA, the hold harmless rule does not apply to you at all, meaning there's no floor protecting your net check from a premium increase. If your income crossed into a new IRMAA bracket for 2026, your Part B premium could have jumped by $80 to $300 a month or more, which would explain a "price increase" that looks like a shrinking check rather than a growing one. If your income has since dropped (retirement, a one-time gain that didn't recur), you can request a reduction using Form SSA-44, which lets you use more recent income if you've had a qualifying life event like retirement, divorce, or loss of a pension.
Other reasons your Social Security check didn't rise as expected
Medicare Part B and IRMAA explain most "why didn't my check go up" cases, but a few other things can eat into a COLA raise:
- Overpayment recovery. If SSA determined you were previously overpaid, they may be withholding a portion of each check (up to 100% in some cases, though a 2024 policy change caps default withholding at 10% for most new overpayments) to recover the balance. A COLA raise doesn't pause an active recoupment.
- Federal tax withholding. If you elected voluntary tax withholding on your benefit (form W-4V), a percentage of your gross benefit, not just the increase, is withheld before deposit.
- Garnishment for child support, alimony, or federal debts. Certain debts can be garnished directly from Social Security, including SSDI. SSI is generally protected from garnishment.
- Medicare Part D IRMAA. If you have a Medicare Part D prescription drug plan and your income exceeds the same thresholds as Part B IRMAA, you pay an added Part D surcharge, separately billed or deducted, ranging from about $14.50 to $91 a month for 2026.
- A Medicare Advantage or Part D plan premium change. If you're in a Medicare Advantage plan, your plan's premium (separate from Part B) may have changed for 2026 during open enrollment, independent of anything SSA or CMS did to the standard premium.
How to check your own 2026 numbers
- Find your COLA notice. SSA mails a COLA notice each December, and it's also available in your online my Social Security account under "Message Center" or "Benefits & Payments."
- Confirm your new gross monthly benefit (before deductions) on that notice.
- Subtract the new Part B premium ($202.90 standard, or your specific IRMAA tier from the table above).
- Subtract any other known withholding (tax withholding percentage, garnishment amount, overpayment recovery amount).
- Compare that net number to your actual December 2025 net deposit. The difference is your real 2026 raise.
If the math doesn't match what actually hit your account, that's a sign something else is happening, most commonly an overpayment notice you may have missed, and it's worth calling SSA at 1-800-772-1213 or checking your online statement rather than assuming a system error.
What about 2027?
The 2027 COLA has not been announced as of this writing. SSA typically announces the following year's COLA in mid-October, based on third-quarter CPI-W inflation data. Any number you see online for 2027 before that announcement is a projection, not a final figure. For current projections and how they're calculated, see Social Security COLA 2027 and SSDI COLA 2027 projection.
Frequently Asked Questions
Why did my Social Security check only go up a little when the COLA was 2.8%?
Because the 2.8% COLA is applied to your gross benefit, but your net deposit also reflects the 2026 Medicare Part B premium increase of $17.90 a month (from $185.00 to $202.90), and if applicable, any IRMAA surcharge. The COLA raised your gross benefit correctly; Medicare simply took a larger deduction than it did in 2025.
Is it true that Medicare "eats" the Social Security raise every year?
Not entirely, and not for everyone. In 2026, the average dollar COLA increase (about $56) is larger than the Part B premium increase ($17.90), so most people still see a net increase. The concern is real mainly for people whose individual gross benefit is low enough that 2.8% of it comes to less than the Part B increase, and for people who moved into a higher IRMAA bracket.
What is the hold harmless rule and does it apply to me?
It's a federal rule preventing your net Social Security check from dropping below the prior year's amount due to a Part B premium increase, if your premium is deducted from your check, you don't pay IRMAA, you're not new to Part B, and you're not on Medicaid. It caps your effective premium increase so your check doesn't fall, but it doesn't guarantee the full COLA reaches your deposit.
Why did my Medicare premium go up more than the standard amount?
If your 2024 tax return showed income above $109,000 (single) or $218,000 (married filing jointly), you're paying an IRMAA surcharge on top of the standard $202.90 Part B premium for 2026. If your income has dropped since 2024 due to retirement or another qualifying event, you can file Form SSA-44 to request a recalculation using more current income.
Can I get help paying my increased Medicare Part B premium?
Depending on your income and assets, you may qualify for a Medicare Savings Program, which can pay your Part B premium for you, or for Extra Help with Part D drug costs. Eligibility varies by state and household size, and a benefits screening tool can check this alongside SSDI and other programs you may qualify for.
When will the 2027 COLA be announced?
SSA typically announces the following year's COLA in mid-October, based on third-quarter Consumer Price Index data. There is no confirmed 2027 figure yet; any number circulating before the official announcement is a projection.
