Your Parents Left You Their IRA: 6 Rules That Can Make an Inherited IRA Surprisingly Complicated

Inheriting an IRA can feel like receiving a financial gift with one tiny catch: the gift comes with a rulebook. The account may contain a meaningful amount of money, but the IRS controls how and when many beneficiaries can take it out, and those rules depend on who inherited the account, when the original owner died, and whether the owner had already reached the age for required minimum distributions.

That makes an inherited IRA one of those financial situations where doing nothing can feel like the safest move, even though procrastination can create problems. A beneficiary who knows the basic rules can make smarter decisions about withdrawals, taxes, and deadlines instead of discovering an unpleasant surprise when tax season rolls around.

1. The 10-Year Rule Does Not Mean “Ignore It for 10 Years”

For many non-spouse beneficiaries, the SECURE Act created a 10-year deadline that requires the entire inherited IRA balance to leave the account by December 31 of the 10th year following the original owner’s death.

That sounds wonderfully simple until another rule enters the room, because some beneficiaries must take annual required minimum distributions during that 10-year period when the original owner died on or after the required beginning date. The IRS finalized regulations that apply these beneficiary RMD rules beginning in 2025, so the old assumption that every beneficiary can simply wait until year 10 no longer works in every situation.

2. Your Relationship to the Owner Changes the Rules

A surviving spouse gets options that a typical adult child does not, including the ability in many circumstances to treat an inherited IRA as their own IRA or roll it into their own IRA. That choice can significantly change when withdrawals become mandatory and how the account fits into the spouse’s broader retirement strategy.

An adult child generally falls under the 10-year rule, while certain beneficiaries receive special treatment. The IRS classifies a surviving spouse, a minor child, a disabled or chronically ill individual, and an individual who stands no more than 10 years younger than the account owner as eligible designated beneficiaries, although different rules can apply once a minor child reaches the age of majority.

3. The Original Owner’s Age Matters More Than You Might Expect

The date of death does not tell the whole story, because the IRS also looks at whether the IRA owner had reached their required beginning date for RMDs. If the owner died after that point, a beneficiary subject to the 10-year rule generally must continue taking annual RMDs during the 10-year window, then empty the remaining balance by the deadline.

If the owner died before the required beginning date, a beneficiary subject to the 10-year rule generally can wait until the 10th year to empty the account, although taking earlier withdrawals may make sense for tax or financial-planning reasons. This distinction creates a particularly sneaky trap because two people can inherit similarly sized IRAs from parents who die around the same time and face different withdrawal schedules.

4. Traditional and Roth Inherited IRAs Behave Differently at Tax Time

Money from an inherited traditional IRA generally counts as taxable income when the beneficiary withdraws it, because the original account owner typically deferred income taxes on those retirement dollars. That does not mean every dollar automatically faces tax, but it does mean a large withdrawal can push taxable income higher in the year of the distribution.

An inherited Roth IRA usually offers a much friendlier tax picture, since qualified Roth distributions generally avoid federal income tax, but beneficiaries still must follow inherited-account distribution rules. The IRS notes that earnings from a Roth IRA can face tax in certain circumstances when the original Roth account had not satisfied the five-year requirement, so “Roth means everything is automatically tax-free” goes a little too far.

5. Taking Everything at Once Can Create a Giant Tax Bill

An inherited IRA beneficiary can generally take a lump-sum distribution, but “can” does not necessarily mean “should.” A large traditional IRA withdrawal can pile taxable income onto wages, investment income, or other retirement income during the same year, potentially producing a much larger tax bill than a beneficiary expected.

Spreading taxable withdrawals across several years can sometimes make more sense, particularly when the beneficiary expects lower income in certain years. A beneficiary who inherits a sizable traditional IRA should consider the tax consequences before transferring a large chunk of the account into a checking account simply because the money has become available.

6. The Paperwork and Beneficiary Details Matter

The inherited IRA needs proper handling with the custodian, and the beneficiary should confirm the account’s registration, beneficiary designation, date of death, account type, and applicable distribution schedule. Multiple beneficiaries can create additional complications, while trusts and estates can trigger different rules from those that apply to an individual beneficiary.

The year-of-death RMD can also matter, because if the original owner had an RMD due and did not take the full amount before death, the beneficiaries generally must handle the remaining amount. Keeping statements, beneficiary paperwork, withdrawal records, and tax forms together can turn an inherited IRA from a paperwork scavenger hunt into a manageable financial task.

The Best Inheritance May Be a Plan, Not a Payout

An inherited IRA can look deceptively straightforward on a brokerage statement, but the tax treatment and withdrawal schedule can change depending on the beneficiary, the original owner’s age, the date of death, and whether the account holds traditional or Roth money. The biggest mistake often involves treating the 10-year rule as a universal “do nothing until year 10” permission slip, because some beneficiaries face annual RMD requirements along the way.

Before moving substantial money, a beneficiary should confirm the applicable rules with the IRA custodian and consider getting personalized tax advice when the account carries significant value or unusual beneficiary circumstances. The IRS itself recommends reviewing the IRA’s plan documents or checking with the custodian or trustee for specific provisions, which makes sense when one wrong assumption can turn a generous inheritance into an unnecessarily complicated tax problem.
