Inherited IRA rules have changed dramatically over the past several years, and many clients—and even some advisors—are unclear on how they work.
With final IRS regulations now fully in effect beginning in 2025 and continuing into 2026, this is the first full planning cycle where beneficiaries must comply with updated RMD rules under the SECURE Act framework.
This means two things for financial professionals: urgency and opportunity.
With proper planning, beneficiaries can reduce tax exposure, avoid penalties, and make wiser long-term decisions with inherited retirement assets, but these strategies need to be explored sooner rather than later.
Let’s unpack the inherited IRA rules in 2026, including the 10-year rule, RMD requirements, spousal options, and tax strategies, so that you can deliver the guidance your clients need in 2026.
Key RMD Updates and Retirement Rule Changes
RMDs must generally be taken by December 31 each year. If the full amount isn’t withdrawn on time, the IRS may assess a penalty of up to 25% of the missed distribution, which can potentially be reduced to 10% if the error is corrected quickly.
Here’s what else you need to know:
- For most pre-tax retirement accounts, RMDs now begin at age 73 for individuals born between 1951 and 1959
- Changes introduced through the SECURE 2.0 Act removed lifetime RMD requirements from Roth 401(k) and Roth 403(b) accounts, allowing original owners to keep funds invested longer
- Despite this update, beneficiaries who inherit Roth employer-sponsored accounts are still generally subject to distribution requirements based on inherited account rules
What Is the 10-Year Rule for Inherited IRAs?
The 10-year rule, established in 2019 by the SECURE Act, requires most non-spouse beneficiaries to fully distribute inherited IRA assets by December 31 of the tenth year following the original owner’s death. Previously, beneficiaries could “stretch” withdrawals over their lifetime, but not anymore.
This rule applies to:
- Traditional inherited IRAs
- Roth inherited IRAs
- Most non-spouse beneficiaries
There’s no early withdrawal penalty on inherited IRA distributions, regardless of the beneficiary’s age. However, withdrawals from traditional IRAs remain taxable as ordinary income.
The key planning challenge isn’t whether funds must be withdrawn, but when and how.
RMD Requirements During the 10-Year Window
One of the biggest sources of confusion has been whether annual RMDs are required during the 10-year window. Final IRS regulations clarified this beginning in 2025 and continuing into 2026.
If the original owner died before RMD age (and had not yet begun RMDs):
- No annual RMDs are required for the beneficiary
- The beneficiary has flexibility on timing
- The account must still be fully distributed by year ten
This allows advisors to model withdrawals strategically over the decade.
If the original owner died after RMD age (and had already begun RMDs):
- Beneficiaries must take annual RMDs in years 1–9
- The account must still be fully distributed by year ten
- RMDs are based on the beneficiary’s life expectancy
And yes: missing these annual RMDs can trigger penalties. That’s why proactive planning with your clients is essential this year and beyond.
Smart Tax-Advantaged Distribution Strategies Advisors Should Consider
Strategic distribution planning can significantly reduce tax exposure and help beneficiaries make more informed, long-term decisions about inherited retirement assets. Some strategies you can explore with clients include:
Evenly spreading withdrawals across ten years:
- Rather than waiting until year ten, level distributions may reduce total tax liability
Coordinating with income timing, since withdrawals can be timed around:
- Retirement
- Career breaks
- Business losses
- Lower-income years
Incorporating Roth conversion planning for spousal beneficiaries or certain situations, for example:
- Partial Roth conversions may reduce long-term tax exposure
- Creates future tax-free income
Using charitable strategies for philanthropically inclined clients:
- Qualified charitable distributions (where eligible)
- Donor-advised fund strategies
- Offset high-income years
Advisors who model multi-year tax projections deliver significantly more value than those treating inherited IRAs as simple distribution accounts.

Spousal Inherited IRA Options in 2026
Spouses retain the most flexibility when inheriting retirement assets. Here are three strategies a surviving spouse can consider:
1. Roll the IRA into their own
- They can treat it as their own retirement account
- This delays RMDs until their own required age
- It allows continued tax-deferred growth
- This is often ideal when the surviving spouse is younger or doesn’t need immediate income
2. Keep it as an inherited IRA
- This may allow earlier access without penalties
- It’s useful if the spouse is under the age of 59½
- RMD rules are based on the inherited structure
3. Use life expectancy withdrawals
- Spouses can stretch distributions based on life expectancy, creating long-term tax efficiency
- The decision affects RMD timing and Roth conversion opportunities
- It also impacts tax bracket management and estate planning outcomes
Before recommending a specific path to a surviving spouse, it’s essential to model multiple scenarios to determine which makes the most sense for the clients’ overall plans.
Using Trusts as IRA Beneficiaries
Trusts are frequently named as IRA beneficiaries for control and protection, but require careful review under current rules. Trust planning could make sense in cases involving blended families, spendthrift heirs, minor beneficiaries, or asset protection concerns.
However,many conduit trusts were created before the SECURE Act assumed lifetime stretch distributions.
Under current rules in 2026:
- Some trusts now force accelerated distributions
- Trust tax brackets are highly compressed
- Coordination with 10-year rule is important
As a financial professional, you can encourage your clients to review their beneficiary designations and trust language to ensure they remain in compliance with current regulations.

Common Advisor Mistakes with Inherited IRAs
Despite more explicit guidance heading into 2026, inherited IRA planning mistakes remain common—and costly. Even minor oversights can trigger avoidable penalties or create unnecessary tax burdens for beneficiaries.
Here’s a quick checklist of the frequent errors advisors should watch for based on what we’ve explored so far:
- Assuming no annual RMDs are required: Some advisors mistakenly focus only on the 10-year deadline and overlook that annual RMDs may still apply when the original owner has already begun distributions.
- Missing inherited IRA RMD deadlines: As previously mentioned, failing to complete required distributions by December 31 can trigger penalties of up to 25% of the amount not withdrawn.
- Failing to review beneficiary designations: Outdated or improperly structured beneficiary designations can significantly impact distribution timing, tax treatment, and planning flexibility.
- Ignoring multi-year tax modeling: Inherited IRAs are often handled as transactional accounts rather than strategic planning opportunities. But without multi-year tax modeling, beneficiaries may withdraw too much in high-income years or spike into higher tax brackets.
- Overlooking trust implications: Trusts named as IRA beneficiaries require careful coordination with current SECURE Act rules. Failing to review trust language may result in accelerated distributions, compressed trust tax rates, or misalignment with the client’s estate goals.
Being aware of these common mistakes and making it clear that you’re avoiding them sets you apart as a proactive advisor rather than a reactive one. Most importantly,it allowsyou to deliver greater value and better outcomes for your clients.
Making Inherited IRA Planning a Strategic Advantage
Inherited IRA rules in 2026 are loud and clear, but they’re also more complex.
