Does a Pension Count as Income for Social Security? Taxes and Medicare

A pension does not count as income for Social Security retirement purposes. The Social Security Administration counts only wages and net self-employment income when it applies the retirement earnings test, so payments from a private pension, a 401(k), a 403(b), or a traditional IRA will not reduce your monthly benefit.¹ Pension income can still reach your Social Security in indirect ways: it can make more of your benefit taxable, raise your Medicare premiums, and disqualify you from Supplemental Security Income.

Why a Pension Doesn’t Reduce Your Retirement Benefit

If you claim Social Security before your full retirement age and keep working, the retirement earnings test can temporarily withhold part of your check. In 2026, Social Security withholds $1 for every $2 you earn above $24,480 if you are under full retirement age for the entire year. In the year you reach full retirement age, the limit rises to $65,160 and the withholding drops to $1 for every $3 above that amount. Once you hit full retirement age, the test stops applying entirely.²

The earnings test looks at earned income only. Pension checks, annuity payments, and withdrawals from retirement accounts fall outside that definition, so they are excluded from the calculation. You can draw a substantial pension and collect your full Social Security benefit at the same time.¹

Government Pensions: The WEP and GPO Are Gone

Until recently, two rules cut Social Security benefits for people who also drew a pension from a government job that did not withhold Social Security taxes. The Windfall Elimination Provision reduced the retiree’s own Social Security benefit, and the Government Pension Offset reduced spousal and survivor benefits by two-thirds of the government pension amount. Both hit public-sector retirees such as teachers, firefighters, police officers, and certain federal workers.

The Social Security Fairness Act, Public Law 118-273, was signed on January 5, 2025 and repealed both provisions. December 2023 was the last month either rule applied, and benefits payable from January 2024 forward are calculated without any WEP or GPO reduction. The Social Security Administration began adjusting monthly payments in February 2025 and issued one-time retroactive payments covering the increase back to January 2024.³

If you never filed for Social Security because WEP or GPO would have eliminated your benefit, you can apply now. Retroactivity on a new application is generally limited to six months before the filing month, so waiting costs you benefits.³

How a Pension Can Make Your Social Security Taxable

Pension distributions raise your adjusted gross income, and the IRS uses a figure called combined income (adjusted gross income, plus nontaxable interest, plus half of your Social Security benefits) to decide how much of your Social Security is subject to federal income tax.⁴

The thresholds have not been adjusted for inflation since 1993:

Single filers with combined income below $25,000: benefits are not taxed.
Single filers between $25,000 and $34,000: up to 50 percent of benefits may be taxable.
Single filers above $34,000: up to 85 percent of benefits may be taxable.
Joint filers with combined income below $32,000: benefits are not taxed.
Joint filers between $32,000 and $44,000: up to 50 percent of benefits may be taxable.
Joint filers above $44,000: up to 85 percent of benefits may be taxable.

Because the thresholds are frozen, even a modest pension often pushes a retiree past the first line. A single retiree with a $2,000 monthly pension and $1,500 in monthly Social Security has a combined income of at least $33,000, well past the $25,000 mark.⁴

How a Pension Can Raise Your Medicare Premiums

Medicare Part B premiums are tied to your modified adjusted gross income from two years earlier. Pension payments, 401(k) withdrawals, and traditional IRA distributions all count toward that figure, so a large pension or a lump-sum retirement account withdrawal can push you into a higher premium bracket through the Income-Related Monthly Adjustment Amount.

In 2026, single filers at or below $109,000 (joint filers at or below $218,000) pay the standard Part B premium of $202.90 per month. Above those thresholds, surcharges apply in tiers:⁵

$109,001 to $137,000 single / $218,001 to $274,000 joint: $284.10 per month
$137,001 to $171,000 single / $274,001 to $342,000 joint: $405.80 per month
$171,001 to $205,000 single / $342,001 to $410,000 joint: $527.50 per month
$205,001 to $499,999 single / $410,001 to $749,999 joint: $649.20 per month
$500,000 or more single / $750,000 or more joint: $689.90 per month

The surcharge applies per person, so both spouses on a joint return that exceeds the threshold pay it.⁵

Supplemental Security Income Is Different

Supplemental Security Income is a need-based program, not a Social Security retirement benefit, and its rules on pension income are far stricter. Nearly every kind of pension payment (private pensions, veterans’ benefits, disability payments from a former employer, and railroad retirement annuities) counts as unearned income for SSI purposes.⁶

SSI allows a $20 monthly exclusion from unearned income. After that, every dollar of pension reduces your SSI payment by a dollar.⁷ In 2026 the maximum federal SSI benefit is $994 per month for an individual and $1,491 for a couple.⁸ A $300 monthly pension would cut an individual’s SSI check to $714 after the $20 exclusion.

SSI also has a resource cap: $2,000 for an individual and $3,000 for a couple in 2026. If you can access a 401(k) or IRA, its balance may count toward that limit, and exceeding the limit at the start of a month makes you ineligible for that month’s payment.⁹

A VA non-service-connected pension gets treated as need-based unearned income, which means it does not qualify for certain SSI income exclusions available for other unearned income. The full amount, after the standard $20 exclusion, reduces SSI dollar for dollar.

A Note on Social Security Disability

If you receive Social Security Disability Insurance, a private pension will not reduce it. The disability offset that people sometimes worry about applies to workers’ compensation and certain other public disability payments, not to employer pensions. Under 42 USC 424a, combined benefits from those specific sources cannot exceed 80 percent of your pre-disability average earnings, and any excess is subtracted from your disability check until you reach full retirement age or the other payments stop. Veterans Affairs benefits and need-based assistance are excluded from that offset.¹⁰
