You inherited an IRA from a beneficiary, not the original owner. That distinction matters because you generally assume the existing distribution schedule and don’t start a new timeline. As a result, your options may be more limited than what is available for direct beneficiaries. Overlooking these requirements could accelerate withdrawals, and, if you ignore the rules, cost you more in taxes and penalties.
Why a Second-Generation IRA Is Different
The SECURE Act of 2019 generally requires most nonspouse beneficiaries to fully distribute an inherited IRA within 10 years. 1 Successor beneficiaries may have less time, depending on the schedule already in effect.
For example, if you inherit $300,000 in a traditional IRA with three years remaining, dividing the balance evenly would mean withdrawing $100,000 annually. Equal distributions are not necessarily required, but the account must be emptied by the applicable deadline.
A shorter window can increase taxes because traditional IRA withdrawals generally count as taxable income. Larger distributions could push some earnings into higher marginal brackets, while spreading them across the remaining years might help you manage the impact.
How Much It May Cost to Wait Until the Tax Deadline
Using the example of $300,000 in an inherited IRA, let’s compare spreading distributions evenly over the remaining three years with taking the entire balance at the deadline.
Assuming you are a single filer with $100,000 in taxable income each year before any inherited IRA withdrawals, here’s how the federal tax math works using 2026 marginal rates: 2
| Tax Bracket | Income Range | Amount in Bracket | Tax Rate | Tax Owed |
|---|---|---|---|---|
| 10% | $0–$12,400 | $12,400 | 10% | $1,240 |
| 12% | $12,400–$50,400 | $38,000 | 12% | $4,560 |
| 22% | $50,400–$105,700 | $55,300 | 22% | $12,166 |
| 24% | $105,700–$200,000 | $94,300 | 24% | $22,632 |
| Annual total | — | — | — | $40,598 |
| Three-year total | — | — | — | $121,794 |
Over three years, you’d pay $121,794 in federal income tax total. Of that amount, the inherited IRA distributions account for $71,658 in additional tax, or $23,886 annually. Your baseline $100,000 of taxable income would generate $16,712 each year.
Now, let’s consider waiting until the final year to withdraw the entire $300,000. Your taxable income would reach $400,000 that year, pushing portions of the distribution into the 32% and 35% brackets:
| Tax Bracket | Income Range | Amount in Bracket | Tax Rate | Tax Owed |
|---|---|---|---|---|
| 10% | $0–$12,400 | $12,400 | 10% | $1,240 |
| 12% | $12,400–$50,400 | $38,000 | 12% | $4,560 |
| 22% | $50,400–$105,700 | $55,300 | 22% | $12,166 |
| 24% | $105,700–$201,775 | $96,075 | 24% | $23,058 |
| 32% | $201,775–$256,225 | $54,450 | 32% | $17,424 |
| 35% | $256,225–$400,000 | $143,775 | 35% | $50,321 |
| Total tax at $400,000 | — | — | — | $108,769 |
In the final year, your federal income tax would rise to approximately $108,769. Adding the $16,712 owed on your baseline income in each of the first two years brings the three-year total to $142,193. That’s about $20,399 more than the $121,794 calculated when the inheritance is spread evenly across the same period.
The difference comes from marginal tax rates. Taking $100,000 annually keeps the highest portion of your taxable income in the 24% bracket, while a $300,000 lump sum pushes some into the 32% and 35% ranges. This simplified example assumes taxable income of $100,000 before inherited IRA withdrawals in all three years and does not account for credits, state taxes or other circumstances that could change your actual liability.

What You Do Year-One May Reduce Your Tax Bill
Your first year as a successor beneficiary will determine your options going forward. Start by confirming the IRA’s remaining deadline, current balance and any distributions required for that year. Then compare the timeframe with your taxable income. Taking part of the balance during a lower-income year could help you avoid getting taxed at higher rates. Waiting until the final year will concentrate income and increase your tax bill comparatively.
If the original owner and previous beneficiary were subject to required minimum distributions (RMDs), you may need to continue these withdrawals. Missing a payment triggers a 25% penalty on the shortfall. These mandatory amounts can factor into your overall strategy, allowing you to distribute the balance more strategically throughout the remaining deadline. Even if you plan to empty the account in a lump sum at the end, you must still take RMDs on a regular basis. That means the deadline forces out a set amount no matter what your preference.
