The Hidden Costs of Withdrawing From Your 401(k) or IRA

Retirement savings can help cover a major home repair, a medical bill, or a new car. But before taking a large withdrawal, it is important to understand how that decision could affect your taxes, Medicare premiums, and future financial security.

The amount you withdraw may be greater than the amount you actually have available to spend.

Plan for Taxes Before You Withdraw

Withdrawals from traditional 401(k) accounts and traditional IRAs are generally taxed as ordinary income. Previously taxed contributions may receive different treatment, and qualified Roth withdrawals are generally free of federal income tax.

Reaching age 59½ generally removes the additional early withdrawal tax. It does not make traditional retirement account withdrawals free of ordinary income tax.

For example, if you need $30,000 and assume a combined tax rate of 25% on the entire distribution, you would need to withdraw $40,000 to keep $30,000 after taxes. Your actual tax bill will depend on your individual circumstances.

Consider the Impact on Medicare

A large taxable withdrawal can increase the income used to determine your Medicare premiums. If that income exceeds the applicable thresholds, you could pay an additional amount for Medicare Part B and Part D through the Income Related Monthly Adjustment Amount, commonly called IRMAA.

Medicare generally uses tax information from two years earlier. A withdrawal made this year could therefore increase your premiums two years later, even if your income returns to a lower level.

Understand How Social Security May Be Affected

Additional taxable income can also cause more of your Social Security benefits to become subject to federal income tax.

Depending on your combined income and filing status, up to 85% of your benefits may be included in taxable income. This does not mean you pay an 85% tax rate on those benefits.

Look Beyond the Immediate Expense

A withdrawal reduces the amount remaining in your retirement account and the money available for potential future growth. That does not mean using your savings is a mistake. It means the decision should fit within a plan that also accounts for ongoing living expenses and future needs.

Before requesting a distribution, review the amount you need after taxes, the potential effect on Medicare premiums, and the savings that will remain.

Comparing available funding sources or spreading an expense across calendar years may help in some situations. Neither option is automatically better, and the timing must also account for tax payment requirements.

Make an Informed Decision

Your retirement savings are there to support your life. Understanding the full cost of a withdrawal can help you use them with greater confidence.

A qualified tax professional or financial advisor can help evaluate your options before you take the money, giving you a clearer picture of both the immediate expense and its future impact.
