These inherited IRA mistakes could reduce your windfall, advisors say. How to avoid them

New IRS regulations for inherited IRAs, notably the '10-year rule' and mandatory RMDs for non-spouse beneficiaries commencing in 2025, introduce significant tax complexities and potential penalties, impacting the projected $100 trillion 'great wealth transfer.' Advisors emphasize the critical need for beneficiaries to understand these rules, conduct multi-year tax planning to optimize withdrawal strategies and mitigate substantial tax liabilities, and strategically re-evaluate inherited investment portfolios to align with personal risk tolerance and financial goals.

Analysis

The IRS has introduced complex regulations for inherited IRAs, notably the "10-year rule" requiring beneficiaries to empty accounts within a decade of the original owner's death. Starting in 2025, non-spouse beneficiaries, such as adult children, must also commence required minimum distributions (RMDs) over this 10-year period. These changes are particularly relevant given the projected "great wealth transfer" of over $100 trillion by 2048, as reported by Cerulli Associates.

Failure to comply with the new RMD requirements for inherited IRAs can result in a substantial 25% IRS penalty on the under-withdrawn amount, though this can be reduced to 10% if corrected within two years. Inheriting a pretax IRA means withdrawals are subject to regular income taxes, necessitating careful multi-year tax planning. Advisors warn against taking a large lump sum in the final year, as this can lead to "significant taxes."

Beyond tax considerations, beneficiaries often err by not re-evaluating the inherited IRA's investment allocation. Financial advisors emphasize aligning investments with the heir's personal risk tolerance, financial goals, and timeline, while also factoring in tax liabilities and RMD schedules. The overall sentiment surrounding these changes is moderately negative and cautious, reflecting the increased complexity and potential for costly mistakes for beneficiaries.

Key Decisions for Investors

• Beneficiaries of inherited IRAs must thoroughly understand the "10-year rule" and the new RMD requirements for non-spouse beneficiaries starting in 2025 to avoid significant IRS penalties.
• Engage in multi-year tax projections with a financial advisor to optimize withdrawal strategies from inherited pretax IRAs, mitigating substantial tax liabilities in later years.
• Proactively review and adjust the inherited IRA's investment portfolio to align with personal risk tolerance, financial goals, and the new RMD schedule, considering potential tax implications.
