If you inherited an IRA from a parent, spouse, or relative in the last few years, you may be sitting on a tax deadline you didn't know existed. The inherited IRA 10 year rule requires many beneficiaries to take annual distributions, and missing the December 31 deadline can trigger a steep IRS penalty. We've seen this catch too many South Florida families off guard, especially those who assumed they could simply wait until year ten to empty the account.
This confusion is understandable. When the SECURE Act eliminated the "stretch IRA" for most non-spouse beneficiaries, it replaced it with a 10 year rule that sounded simple: empty the account within 10 years, take distributions whenever you want. Then the IRS issued final regulations in 2024 clarifying that if the original account owner had already started required minimum distributions (RMDs), the beneficiary must continue taking annual RMDs during the 10 year window, not just a lump sum at the end. For 2026, this rule is in full effect, and the IRS is no longer waiving penalties for missed annual distributions the way it did during the transition years of 2021 through 2024.
What the Inherited IRA 10 Year Rule Actually Requires
The 10 year rule applies to most non-spouse beneficiaries who inherited an IRA from someone who died on or after January 1, 2020. Under this rule, the entire inherited IRA balance must be withdrawn by December 31 of the tenth year following the year of death.

The twist that trips people up involves whether the original IRA owner was already taking RMDs at the time of death. There are two distinct tracks:
- Track 1, the owner died before their required beginning date: The beneficiary has full flexibility. No annual RMDs are required, but the entire account must be emptied by the end of year 10.
- Track 2, the owner died on or after their required beginning date: The beneficiary must take annual RMDs in years 1 through 9, calculated using the IRS Single Life Expectancy Table, and the remaining balance must be withdrawn in year 10.
This second track is where the annual distribution requirement lives, and it's the piece that caught thousands of beneficiaries by surprise when final IRS regulations confirmed it in mid-2024.
Why This Matters More in 2026
The IRS officially began enforcing the 50% excess accumulation penalty (reduced to 25%, or 10% if corrected promptly, under current rules) starting with the 2025 tax year. That means 2026 is the second year beneficiaries face real financial consequences for skipping their annual distribution. Miami-area entrepreneurs managing inherited retirement accounts alongside business cash flow need to treat this December 31 deadline with the same seriousness as quarterly estimated tax payments.
Calculating Your Required Annual Distribution
Your annual RMD under the 10 year rule is calculated using the account balance as of December 31 of the prior year, divided by a life expectancy factor from the IRS Single Life Expectancy Table, based on the beneficiary's age in the year following the owner's death and reduced by one each subsequent year.
Example 1: The Single Beneficiary
Maria, a 52 year old small business owner in Coral Gables, inherited her father's traditional IRA in 2022. Her father was 78 and already taking RMDs. Her initial life expectancy factor at age 53 (the year after death) was 33.4. Using the $500,000 account balance as of December 31, 2025, her 2026 RMD calculation looks like this:
- Account balance (12/31/2025): $500,000
- Life expectancy factor (adjusted for 2026, year 4 of the schedule): 30.4
- Required 2026 distribution: $500,000 to 30.4 = $16,447.37
If Maria skips this distribution, the penalty is 25% of the shortfall, or $4,111.84, reducible to 10% ($1,644.74) if corrected within the IRS correction window.
Example 2: The Higher Balance Account
Carlos inherited a $1.2 million IRA from his mother in 2021 when she was 81 and taking RMDs. By 2026, his adjusted life expectancy factor is 24.9. His required distribution:
- Account balance (12/31/2025): $1,200,000
- Life expectancy factor: 24.9
- Required 2026 distribution: $1,200,000 to 24.9 = $48,192.77
For Carlos, a business owner working with our team on business tax strategy, this distribution adds meaningfully to his ordinary taxable income for 2026 and needs to be factored into his overall withholding and estimated payment planning well before Q4 estimates are due in January 2027.
Example 3: The Missed Deadline
Jennifer, a Miami-Dade County physician, inherited a $300,000 IRA in 2023 and forgot to take her required 2026 distribution of $9,900. She discovered the error in February 2027 while gathering documents for her return. Because she corrected it within the IRS's two year correction window, her penalty dropped from the full 25% ($2,475) to 10% ($990), but she still owed that amount plus the original distribution's ordinary income tax.
Annual RMD Table by Beneficiary Age
| Beneficiary Age in Year After Death | Initial Life Expectancy Factor | Approximate Distribution Period Remaining by 2026 |
|---|---|---|
| 40 | 43.6 | Year 4 to 7, factor around 39 to 40 |
| 50 | 34.2 | Year 4 to 7, factor around 30 to 31 |
| 60 | 25.2 | Year 4 to 7, factor around 21 to 22 |
| 70 | 17.0 | Year 4 to 7, factor around 13 to 14 |
Note: These figures illustrate the declining factor method under the IRS Single Life Expectancy Table and should be verified against the current year's published table for your exact inheritance year.
Track 1 vs Track 2: A Side-by-Side Comparison
| Factor | Track 1 (Owner Died Before RMD Age) | Track 2 (Owner Died After RMD Age) |
|---|---|---|
| Annual RMDs required in years 1 to 9 | No | Yes |
| Full balance due by | December 31 of year 10 | December 31 of year 10 |
| Penalty for missed annual RMD | Not applicable | Up to 25%, reducible to 10% |
| Flexibility on timing within 10 years | High | Limited by annual RMD requirement |
| Common beneficiary mistake | Waiting until year 10 to withdraw everything, creating a large tax bill | Forgetting the annual RMD entirely |
Steps to Stay Compliant Before December 31
- Confirm which track applies to your inherited IRA. Pull the original account owner's age and RMD status at death. If you're unsure, our team can review the account history as part of a virtual CPA engagement.
- Request the December 31, 2025 balance from your custodian. This figure anchors your 2026 RMD calculation.
- Identify your correct life expectancy factor. Use the IRS Single Life Expectancy Table and subtract one year for each year since your initial calculation.
- Calculate and schedule the distribution before December 31, 2026. Many custodians allow automatic annual distributions, which removes the risk of forgetting.
- Set aside funds for the tax liability. Distributions are taxed as ordinary income and may push you into a higher bracket, especially when combined with business income.
- Document everything. Keep records of your calculation method in case of an IRS inquiry.
How This Affects South Florida Business Owners and High Income Individuals
South Florida business owners often inherit IRAs while simultaneously managing pass-through business income, rental properties, and investment portfolios. Stacking an inherited IRA RMD on top of this income can unexpectedly push you into a higher marginal bracket or trigger the Net Investment Income Tax threshold.
We regularly see this scenario with Miami-area entrepreneurs who assume their accountant is tracking the inherited IRA alongside their business returns. In reality, inherited IRA custodians rarely coordinate with your business tax preparer, which is why bundling this into comprehensive managed accounting makes practical sense. Coordinating your inherited IRA distribution schedule with your business's quarterly estimates prevents the kind of April surprise that catches so many filers.
If you're also running day to day bookkeeping for a small business, integrating your inherited IRA distribution planning into your small business bookkeeping process ensures nothing falls through the cracks between personal and business tax obligations.
Common Planning Opportunities Within the 10 Year Window
Beneficiaries aren't locked into taking only the minimum. Strategic beneficiaries sometimes choose to withdraw more than the required annual amount in lower income years to smooth out their tax liability across the 10 year window, rather than facing one enormous distribution in year 10.
For example, a beneficiary expecting a large capital gain from a business sale in year 8 might accelerate inherited IRA withdrawals in years 4 through 6 instead, when their income is comparatively lower. This kind of multi-year planning requires coordination with both your CPA and your estate attorney, and it's a conversation worth having well before December 31 rather than in the final weeks of the year.
Frequently Asked Questions
Q: Do I have to take an annual RMD from my inherited IRA under the 10 year rule? A: It depends on whether the original account owner had already reached their required beginning date for RMDs before passing away. If they had, you must take annual distributions in years 1 through 9 and empty the account by year 10. If they had not yet reached that age, you have flexibility to withdraw on any schedule as long as the account is empty by December 31 of year 10.
Q: What happens if I miss the December 31 deadline for my inherited IRA distribution? A: The IRS imposes an excise tax penalty on the amount you should have withdrawn but didn't, currently set at 25%, which can drop to 10% if you correct the mistake within the IRS's designated correction window. You'll also owe ordinary income tax on the distribution once you take it.
Q: Does the 10 year rule apply to spouses who inherit an IRA? A: No. Spousal beneficiaries have special options, including treating the IRA as their own or using a different distribution schedule based on their own life expectancy. The 10 year rule primarily affects non-spouse beneficiaries such as adult children, siblings, and other heirs.
Q: How is my inherited IRA distribution taxed if I live in Florida? A: Florida has no state income tax, so your inherited IRA distribution is only subject to federal ordinary income tax. However, South Florida residents with significant business income should still plan carefully, since a large distribution can push total taxable income into a higher federal bracket or trigger additional Medicare surtaxes.
Q: Can I roll my inherited IRA into my own retirement account to avoid the 10 year rule? A: Only spousal beneficiaries can roll an inherited IRA into their own account. Non-spouse beneficiaries, including adult children, must maintain the account as an inherited IRA and follow the 10 year distribution rules regardless of their relationship to the deceased.
Q: What's the biggest mistake Miami-area beneficiaries make with inherited IRAs? A: The most common mistake is assuming the 10 year rule means no distributions are required until the final year. Beneficiaries subject to annual RMDs who skip years 1 through 9 face compounding penalties and a much larger, more painful tax bill when they're forced to withdraw a decade's worth of growth all at once in year 10.
