Retirement accounts pass by designation
Retirement accounts (IRA, 401(k)), along with 403(b)s, pensions, and annuities, pass to whoever is named on the plan's beneficiary designation form. The will and the trust do not control them. An outdated form naming a former spouse, a deceased parent, or no one at all is one of the most common and expensive mistakes in estate planning.
How beneficiaries are taxed
Traditional retirement accounts were funded with pre-tax dollars, so every withdrawal is ordinary income to whoever takes it. Since the SECURE Act, most non-spouse beneficiaries must empty an inherited account within ten years of the owner's death (the "10-year rule"), and, if the owner had already started required distributions, must also take annual withdrawals during that period. Compressing a large balance into ten years can push heirs into much higher tax brackets.
- Surviving spouse
- Can roll the account into their own IRA and continue tax deferral, or treat it as an inherited account if younger than 59½ and likely to need withdrawals.
- Eligible designated beneficiaries
- Minor children of the owner (until age 21), disabled or chronically ill individuals, and beneficiaries not more than ten years younger than the owner may still stretch withdrawals over their life expectancy.
- Everyone else
- Adult children, grandchildren, and most trusts fall under the 10-year rule.
Naming a trust as beneficiary
Parents sometimes prefer not to hand a young or financially inexperienced child an unrestricted account. A properly drafted "see-through" trust can be named as beneficiary, allowing a trustee to control distributions while preserving the available payout period. The drafting is technical; a trust that fails the IRS requirements can trigger immediate taxation of the whole balance. This is an area where the trust and the beneficiary form must be prepared together.
Planning ideas
- Review every designation after a marriage, divorce, birth, or death, and name contingent beneficiaries.
- Consider Roth conversions in lower-income years so that heirs inherit tax-free Roth assets rather than a taxable balance under the 10-year rule.
- Use retirement assets for charitable gifts. A charity pays no income tax on the account, so leaving the IRA to charity and other assets to family can save the family substantial tax. Qualified charitable distributions after age 70½ also count toward required minimum distributions.
- Coordinate with estate tax planning. Retirement accounts are included in the taxable estate at full value; large balances can be a major driver of Minnesota estate tax.
Common questions
Should I name my estate or trust as beneficiary of my IRA?
Naming your estate generally forces the fastest payout and adds the account to probate; it is rarely advisable. A trust can work well when drafted specifically for that purpose. For many people, naming individuals directly with contingents is the simplest approach.
What happens if no beneficiary is named?
The plan's default rules apply. Many plans pay to the estate, which means probate and the least favorable tax treatment. Always name primary and contingent beneficiaries.
Can minor children be named as beneficiaries?
Yes, but a minor cannot legally take control of the account, so a court-supervised conservatorship may be needed. Naming a trust or a custodian under the Minnesota Uniform Transfers to Minors Act avoids this.
Do inherited Roth IRAs follow the 10-year rule?
Yes for most non-spouse beneficiaries, but withdrawals are tax-free, and no annual distributions are required during the ten years, so the account can grow untaxed until the deadline.
