If your Social Security payment shrank, the money almost always went somewhere specific before it reached your bank account. The most common reason a Social Security payment decreases is a Medicare Part B premium deduction, but overpayment recovery, tax withholding, IRS levies, garnishments for child support or defaulted student loans, the earnings test for people still working, and workers’ compensation offsets all pull from the same check. The 2026 cost-of-living adjustment is 2.8%, and that raise can vanish once these deductions apply.1Social Security Administration. How Much Will the COLA Amount Be for 2026
Medicare Part B Premiums Came Out First
For most retirees, this is the answer. The standard Part B premium for 2026 is $202.90 a month, withheld directly from the Social Security payment before it deposits.2Centers for Medicare and Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles When the premium rises from one year to the next, the annual raise gets partially or fully consumed by the increase.
A rule called “hold harmless” prevents most beneficiaries from seeing an actual net drop compared to the prior year: it caps the Part B premium increase at the dollar amount of your COLA. It does not protect everyone. New Medicare enrollees, people who haven’t yet started collecting Social Security, and higher-income beneficiaries subject to IRMAA all fall outside the protection.3Social Security Administration. How the Hold Harmless Provision Protects Your Benefits
IRMAA Surcharges for Higher Incomes
If your modified adjusted gross income from two years ago crosses certain thresholds, Medicare adds an Income-Related Monthly Adjustment Amount on top of the standard Part B premium. The 2026 surcharges are based on your 2024 tax return, and the total monthly premium ranges from $202.90 at the bottom bracket to $689.90 at the top.2Centers for Medicare and Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles All of it comes out of the Social Security payment.
If a life event since 2024 dropped your income — retirement, divorce, or a spouse’s death — you can file Form SSA-44 to ask SSA to base IRMAA on more recent figures instead.
An Overpayment Is Being Recovered
When SSA determines it paid you more than you were owed, it sends a Notice of Overpayment and begins recovering the money from future payments. If you don’t respond within 30 days by repaying, requesting a waiver, or appealing, SSA automatically withholds 50% of your monthly benefit (or 10% of an SSI payment) until the overpayment is recovered.4Social Security Administration. Resolve an Overpayment
Overpayments usually trace back to a change in income, living situation, or marital status that SSA wasn’t told about promptly. People assume the agency will catch up on its own, and then a notice arrives saying they owe thousands. If the standard withholding rate creates hardship, you can ask for a lower amount using Form SSA-634.5Social Security Administration. Request for Change in Overpayment Recovery Rate
Requesting a Waiver
If the overpayment wasn’t your fault and paying it back would cause hardship or be unfair for another reason, you can request a full waiver on Form SSA-632.6Social Security Administration. Request for Waiver of Overpayment Recovery For overpayments of $2,000 or less where you weren’t at fault, SSA can often approve a waiver quickly by phone without the full paperwork. Waivers are not available if you were convicted of fraud related to the overpayment.
You’re Working and Haven’t Hit Full Retirement Age
Collecting retirement benefits while still working before full retirement age triggers the earnings test. For 2026, if you’ll be under full retirement age for the entire year, SSA withholds $1 for every $2 you earn above $24,480. In the calendar year you reach full retirement age, the formula loosens to $1 withheld for every $3 above $65,160, and only earnings in the months before you hit that age count.7Social Security Administration. Receiving Benefits While Working
Those withheld dollars aren’t lost. Once you reach full retirement age, SSA recalculates your monthly benefit upward to account for the months when payments were withheld. That makes the earnings test a deferral rather than a permanent cut, but the check is smaller in the meantime.
Taxes Are Being Withheld or Levied
Social Security benefits can be taxable federal income. If your combined income (adjusted gross income plus tax-exempt interest plus half your Social Security) exceeds $25,000 filing single or $32,000 filing jointly, up to 85% of your benefits become taxable.8Social Security Administration. Must I Pay Taxes on Social Security Benefits Many people ask SSA to withhold federal tax from each payment using IRS Form W-4V. Only four rates are available: 7%, 10%, 12%, or 22%.9Internal Revenue Service. Form W-4V Voluntary Withholding Request If you recently signed one, that’s your smaller check.
If you owe back taxes and haven’t arranged a payment plan, the IRS can levy your Social Security through the Federal Payment Levy Program. Federal law caps this continuous levy at 15% of each monthly payment.10Office of the Law Revision Counsel. 26 USC 6331 – Levy and Distraint The levy continues until the tax debt, interest, and penalties are paid off. The IRS does not need a court order to start it.
A Garnishment Is Taking Part of the Check
Federal law generally protects Social Security from private creditors. A credit card company or medical provider cannot garnish your payment even with a court judgment.11Office of the Law Revision Counsel. 42 USC 407 – Assignment of Benefits Several categories of debt override that protection.
Child support, alimony, and court-ordered restitution can be taken directly from your benefit, and SSA can withhold those amounts without your consent.12Social Security Administration. Can My Social Security Benefits Be Garnished or Levied The Treasury Offset Program can also pull from Social Security for other delinquent federal debts.13Bureau of the Fiscal Service. Treasury Offset Program
Defaulted federal student loans are a common trigger. The first $750 of your monthly benefit is protected from the offset, and beyond that floor the offset is limited to 15% of your total monthly benefit. The $750 threshold hasn’t been adjusted for inflation since 1996.14Consumer Financial Protection Bureau. Social Security Offsets and Defaulted Student Loans
Workers’ Compensation Reduced Your SSDI
If you receive Social Security Disability Insurance and also collect workers’ compensation, SSA reduces your SSDI so the combined payments don’t exceed 80% of your average earnings before you became disabled. SSA uses the highest of several formulas based on your earnings history, and total earnings (including amounts above the Social Security taxable maximum) count toward the calculation.15Social Security Administration. Workers Compensation, Social Security Disability Insurance, and Federal Policy
The offset applies to disabled workers under 65 and their families. Some states have “reverse offset” laws that cut the workers’ comp payment instead. Lump-sum workers’ comp settlements are prorated to a monthly equivalent and subject to the same 80% cap.
Payments Stopped Because of Incarceration
If the check didn’t just shrink but disappeared, incarceration is one explanation. Social Security benefits are suspended when someone is convicted and confined in a correctional facility for more than 30 continuous days. Payments to eligible dependents can continue during the confinement if they were already receiving benefits.16Social Security Administration. Benefits After Incarceration Any payments made for months of incarceration become overpayments to be recovered later. Benefits can be reinstated starting the month after release.
If You Were Affected by WEP or GPO, Read This
For decades, two rules reduced Social Security for people who also earned a pension from work not covered by Social Security taxes (typically state or local government jobs). The Windfall Elimination Provision reduced retirement benefits, and the Government Pension Offset cut spousal and survivor benefits.
The Social Security Fairness Act, signed on January 5, 2025, eliminated both. SSA is recalculating affected payments, and the agency has said processing every case could take more than a year because each requires manual review. If you think your benefit is still being reduced under WEP or GPO and you haven’t received an adjustment, contact SSA directly.17Social Security Administration. Social Security Fairness Act Update
How to Dispute the Decrease
If you believe SSA made a mistake, whether in calculating an overpayment, applying a reduction, or suspending payments, you have 60 days from the date you receive the decision to request reconsideration. You can start online, submit Form SSA-561, or call SSA at 1-800-772-1213.18Social Security Administration. Request Reconsideration
Timing matters for overpayments in particular. If you request reconsideration or a waiver within 30 days of receiving the overpayment notice, SSA pauses collection while it decides your case.4Social Security Administration. Resolve an Overpayment Miss that window and the withholding starts while your appeal is pending.19Social Security Administration. Appeal a Decision We Made If reconsideration is denied, the appeal moves to a hearing with an administrative law judge, then the Appeals Council, then federal district court.
