Do IRA or 401(k) Withdrawals Affect Social Security?
IRA, 401(k) and pension withdrawals don’t reduce your Social Security benefit. Social Security doesn’t count them as earnings, so they don’t trigger the earnings test, even before full retirement age. They do affect what you keep: traditional IRA and 401(k) withdrawals count in the income test that decides how much of your benefit is taxable, they can raise your Medicare premiums two years later, and an IRA counts as a resource for SSI.
Why withdrawals don’t reduce your check
The earnings test that withholds benefits before full retirement age looks only at pay from work: wages and net self-employment earnings. Pensions, annuities, IRA and 401(k) withdrawals, interest, dividends and capital gains don’t count, however large. A 63-year-old who takes $80,000 out of a 401(k) and doesn’t work gets every Social Security check in full.
The same is true for SSDI. Its work limits look at earnings from work, so retirement account withdrawals don’t affect whether you’re still considered disabled.
How withdrawals make more of your benefit taxable
Social Security benefits become taxable when your combined income, half your benefits plus your other income, passes $25,000 on a single return or $32,000 on a joint return. Traditional IRA and 401(k) withdrawals are part of that other income, so each dollar withdrawn can pull more of your benefit into taxable income, up to 85% of it.
For a single retiree with $24,000 of Social Security:
| Traditional IRA withdrawal | Combined income | Taxable Social Security |
|---|---|---|
| $10,000 | $22,000 | $0 |
| $20,000 | $32,000 | $3,500 |
| $30,000 | $42,000 | $11,300 |

Going from $20,000 to $30,000 of withdrawals adds $10,000 of IRA income and $7,800 of newly taxable Social Security, so that $10,000 is taxed as if it were $17,800. Planners call that range the tax torpedo; it runs until 85% of your benefit is taxable. These figures follow the IRS worksheet, and you can work out your own taxable amount with other income included. The 2025 to 2028 senior deduction lowers the tax on your total income but doesn’t change how much of your benefit counts.
Withdrawals that don’t count
- Qualified Roth IRA and Roth 401(k) withdrawals aren’t taxable income, so they don’t count in the combined income test.
- A qualified charitable distribution, sent straight from your IRA to a charity once you’re 70½, is left out of your income. You can give up to $111,000 in 2026, and it counts toward your required minimum distribution.
- Money you move from one retirement account to another in a direct rollover isn’t a withdrawal.
Required minimum distributions
You must start taking withdrawals from traditional IRAs and most 401(k)s at 73, or at 75 for anyone born in 1960 or later. These forced withdrawals count in the combined income test like any others, which is one reason some retirees draw from their IRA in their 60s while they delay Social Security: the withdrawals come out while the benefit isn’t yet taxable, and the accounts are smaller when distributions become mandatory. Waiting also raises the check by 8% a year after full retirement age.
Medicare premiums two years later
Medicare’s income-related surcharges use your modified adjusted gross income from two years earlier, and traditional IRA and 401(k) withdrawals are part of it. In 2026, the surcharge applies when 2024 income was over $109,000 single or $218,000 joint, and it’s deducted from your Social Security check. A large one-time withdrawal, such as for a home purchase or a Roth conversion, can raise the premium for one year. If the income came from a one-time event like retiring, you can ask Social Security to use a more recent year.
SSI is different
SSI has a resource limit of $2,000 for one person, and an IRA or 401(k) you could withdraw from counts toward it, valued at what you could take out after any early withdrawal penalty. Someone applying for SSI with $10,000 in an IRA is over the SSI resource limit until the balance is spent down.
