If a primary beneficiary has predeceased the account owner or for some reason they don't want to claim an inherited 401(k), the money would then go to the next contingent beneficiary named. The beneficiary that inherits 401(k) assets is responsible for paying income tax on the money when they begin withdrawing it.
Other bank accounts such as savings or checking accounts may be left as assets in a person's Will, but a 401(k) account will have a beneficiary attached to it. If you are the beneficiary of a 401(k), or one of several beneficiaries, you will receive it as a taxable inheritance when the account holder dies.
If you received a gift or inheritance, do not include it in your income. However, if the gift or inheritance later produces income, you will need to pay tax on that income.
While the inheritance itself is not subject to federal income tax, beneficiaries are generally required to pay income tax on distributions from the inherited 401(k). The assets in the account would be taxed at the beneficiary's ordinary income tax rate, not the tax rate of the original account owner.
Trust beneficiaries must pay taxes on income and other distributions from a trust. Trust beneficiaries don't have to pay taxes on principal from the trust's assets. IRS forms K-1 and 1041 are required for filing tax returns that receive trust disbursements.
As a general rule, if you withdraw funds before age 59 ½, you'll trigger an IRS tax penalty of 10%. The good news is that there's a way to take your distributions a few years early without incurring this penalty. This is known as the rule of 55.
Another key difference: While there is no federal inheritance tax, there is a federal estate tax. The federal estate tax generally applies to assets over $13.61 million in 2024 and $13.99 million in 2025, and the federal estate tax rate ranges from 18% to 40%.
When you inherit property, the IRS applies what is known as a stepped-up cost basis. You do not automatically pay taxes on any property that you inherit. If you sell, you owe capital gains taxes only on any gains that the asset made since you inherited it.
You don't need to report a cash inheritance on your federal return. The IRS doesn't impose an inheritance tax. Only a handful of states (Iowa, Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania) have some kind of inheritance tax.
5-year rule: If a beneficiary is subject to the 5-year rule, They must empty account by the end of the 5th year following the year of the account holders' death. 2020 does not count when determining the 5 years. No withdrawals are required before the end of that 5th year.
Explore a Roth conversion
This will give your heirs tax-free access to your assets after your death, if you've had the Roth account or made the conversion at least 5 years ago. Otherwise, beneficiaries may owe income tax on non-Roth withdrawals from inherited 401(k)s.
Your 401(k) plan will automatically be inherited by your spouse when you die if you don't name any beneficiaries. But if you didn't have a spouse or they were no longer living, that's where it can get complicated if you didn't name any beneficiaries. Your 401(k) plan would then go through probate.
An inherited IRA may be taxable, depending on the type. If you inherit a Roth IRA, you're free of taxes. But with a traditional IRA, any amount you withdraw is subject to ordinary income taxes.
The easiest way to borrow from your 401(k) without owing any taxes is to roll over the funds into a new retirement account. You may do this when, for instance, you leave a job and are moving funds from your former employer's 401(k) plan into one sponsored by your new employer.
Tax Consequences of Inheriting a Traditional IRA
The main thing to remember about inheriting a traditional IRA is that distributions are generally taxable at the beneficiary's ordinary tax rate. If you inherit an IRA and take money out of it, you'll pay income taxes on it.
Beneficiaries can avoid taxes on a Roth 401(k) inheritance as long as the account holder began making contributions to the account at least five years before the beneficiary started taking withdrawals. For the 2024 tax year and beyond, RMDs aren't required from designated Roth accounts .
Generally, beneficiaries do not pay income tax on money or property that they inherit, but there are exceptions for retirement accounts, life insurance proceeds, and savings bond interest. Money inherited from a 401(k), 403(b), or IRA is taxable if that money was tax deductible when it was contributed.
But when gains are inherited, the loophole zeroes out the gain for tax purposes. As a result, an investment sale that would create a taxable gain for the original owner is tax-free for the inheritor. Example: an investor buys 100 shares of stock for $200. Ten years later, the stock is worth $500.
The best way to avoid the inheritance tax is to manage assets before death. To eliminate or limit the amount of inheritance tax beneficiaries might have to pay, consider: Giving away some of your assets to potential beneficiaries before death. Each year, you can gift a certain amount to each person tax-free.
Immediately after receiving an inheritance, you should notify your local Social Security office.
This means that when the beneficiary withdraws those monies from the accounts, the beneficiary will receive a 1099 from the company administering the plan and must report that income on their income tax return (and must pay income taxes on the sum).
The $1,000 per month rule is designed to help you estimate the amount of savings required to generate a steady monthly income during retirement. According to this rule, for every $240,000 you save, you can withdraw $1,000 per month if you stick to a 5% annual withdrawal rate.
Once you start withdrawing from your traditional 401(k), your withdrawals are usually taxed as ordinary taxable income. That said, you'll report the taxable part of your distribution directly on your Form 1040 for any tax year that you make a distribution.
Mistake #1: Not Starting Your RMD on Time
The rules for RMD starting ages have undergone changes in recent years, leading to confusion among many individuals. In the past, the starting age for RMDs was 70½. However, as of 2023, the starting age stands at 73 and is set to increase to 75 in the future.
