Roth IRAs and trusts
Estate-tax shielding strategies: roth-estate-tax-shielding.md.
SECURE Act era rules apply to both traditional and Roth inherited IRAs for distribution timing; Roth distributions are generally tax-free but timing still matters for stretch elimination and trust mechanics.
Owner lifetime
Roth IRA: no RMDs for original owner (unlike traditional IRA). Conversions and contributions follow Pub. 590-A rules (not re-acquired here).
After owner death — beneficiary categories
Per Pub. 590-B (2025) in p590b-distributions-from-individual-retirement-arrangements-iras-summary:
| Beneficiary type | RMD / distribution pattern (general) |
|---|---|
| Surviving spouse (sole beneficiary) | May elect to treat as own IRA or follow beneficiary rules |
| Eligible designated beneficiary (EDB) | Surviving spouse, minor child, disabled/chronically ill, or not more than 10 years younger — may use life expectancy in some cases |
| Non-EDB individual | 10-year rule — account emptied by end of 10th year after death |
| No designated beneficiary | 5-year or owner life expectancy rules depending on date of death vs RBD |
| Estate as beneficiary | Generally least favorable (no stretch; compressed payout) |
Designated beneficiary is determined as of September 30 of the year after death (with disclaimer and death-before-that-date rules).
10-year rule (SECURE Act)
Most non-spouse beneficiaries must withdraw entire inherited account by December 31 of the year containing the 10th anniversary of death (10-year rule). No annual RMD required in years 1–9 for many beneficiaries, but account must be fully distributed by the deadline. Failure triggers excise tax under excess accumulation rules (Form 5329).
Roth beneficiaries: withdrawals are usually qualified and tax-free, but missing the 10-year deadline still risks penalties on traditional accounts; for Roth, tax cost may be low but compliance remains required.
Trust as IRA beneficiary
A trust is not a designated beneficiary, but trust beneficiaries may be treated as designated beneficiaries if four tests are met (Pub. 590-B):
- Valid trust under state law (or would be but for no corpus).
- Irrevocable or becomes irrevocable at owner's death.
- Beneficiaries with respect to the trust's interest are identifiable from the trust instrument.
- Trustee provides required documentation to IRA custodian.
This is the federal see-through analysis (practitioners often label see-through trusts as conduit or accumulation).
Conduit trust (practitioner term)
Trust instrument requires immediate distribution of all IRA distributions received by the trust to identifiable individual beneficiaries. IRA custodian can look through to individual life expectancies when rules satisfied. Risk: all trust beneficiaries may be treated as designated for RMD aggregation (shortest life expectancy if not separated).
Accumulation trust (practitioner term)
Trust may retain IRA distributions in trust. Harder to qualify for stretch; often subject to 10-year rule at trust level. Higher trust income tax compression if income accumulates in non-grantor trust.
Separate accounts / shares
IRA split into separate accounts or shares per beneficiary by end of year after death may allow separate RMD calculations. Applicable multi-beneficiary trust rules apply for disabled/chronically ill beneficiaries (Pub. 590-B).
Roth-specific planning points
| Topic | Implication |
|---|---|
| Tax-free growth | Trust as beneficiary still needs compliant payout structure |
| Estate inclusion | Roth balance included in estate for estate tax; income tax free to beneficiaries |
| QTIP / marital trust | Roth often better left to individuals or conduit trust for spouse — marital trust as Roth beneficiary is usually poor design |
| Conversion timing | Owner's lifetime conversions reduce estate; beneficiaries inherit tax-free pool |
| Grantor trust | If IRA owned by grantor trust (unusual for IRAs), income taxation follows grantor trust rules — IRAs should name individuals or see-through trusts, not revocable trust, as beneficiary in most plans |
Common pitfalls
- Naming revocable living trust without see-through provisions — may lose stretch/10-year favorable treatment or accelerate taxation.
- Multiple beneficiaries in one trust — shortest life expectancy or 10-year rule for entire account.
- Trust not irrevocable at death — fails see-through test.
- Failing to provide documentation to custodian by deadline.
- Assuming Roth eliminates all post-death compliance — 10-year rule still applies for most non-EDBs.
Coordination with estate plan
Bypass trust typically should not be primary Roth beneficiary. Spousal rollover or individual beneficiary often preferred. For children, conduit see-through trust or outright distribution depending on age, creditor protection, and spendthrift goals.
