Roth estate tax shielding
Educational overview; not legal or tax advice. Illinois situs assumed.
Companion to roth-iras-and-trusts.md (SECURE Act payouts, see-through rules). This note focuses on what is actually includible in the estate and how to minimize transfer tax on Roth-heavy estates.
Core fact: Roth is in the estate
A Roth IRA balance is included in the gross estate at fair market value on the date of death (Form 706 / Illinois Form 700). Beneficiaries generally receive distributions income-tax-free, but estate tax applies to the account value unless an exclusion, marital deduction, or charitable deduction applies.
You cannot move a Roth out of the estate while keeping it inside an IRA. There is no "Roth to irrevocable trust" during life without a taxable distribution first.
What actually shields Roth from estate tax
| Strategy | How it works | Limits |
|---|---|---|
| Pay conversion tax from non-IRA assets | Lifetime traditional→Roth conversions shrink the trad IRA in the estate; income tax paid from brokerage/cash reduces estate dollar-for-dollar | Roth balance still includible; you trade estate for income tax |
| Spouse as primary beneficiary + rollover | At first death, surviving spouse rolls Roth into own Roth — marital deduction on Form 706/700; no tax at first death | Full balance in survivor's estate at second death unless other planning used |
| Bypass / credit-shelter at first death (non-Roth assets) | Fund bypass trust up to Illinois $4M exclusion with house, brokerage, etc.; Roth passes to spouse by beneficiary designation | Illinois exclusion not portable — must use first spouse's $4M on non-Roth assets; Roth itself does not fund bypass |
| Charitable beneficiary on Roth | Church (or other 501(c)(3)) named on custodian form — estate charitable deduction; no income tax to charity | Reduces heirs' share; partial designation possible (split beneficiaries) |
| Lifetime gifts after Roth withdrawal | Withdraw Roth (tax-free if qualified), gift cash or securities to heirs or trust | Uses annual exclusion / lifetime credit; loses tax-free growth inside Roth; step-up lost on gifted assets |
| QCD from traditional IRA | Reduces trad IRA at death; cannot use Roth for QCD | Does not shield Roth; complements Roth-heavy plan by shrinking trad IRA |
Federal estate tax: likely $0 at ~$9M gross with 2026-era exclusions. Illinois estate tax: the main driver — ~$800k if both exclusions wasted vs ~$286k if first spouse's $4M bypass is used. See illinois-estate-planner-prep.md.
The real decision: leave Illinois or pay
For a Roth-heavy ~$9M estate, federal planning is largely solved. Illinois is not portable and taxes gross estate over $4M. Most of your wealth is Roth — it must stay in IRAs until death, so it always counts in the gross estate. Bypass/QTIP, conduit trusts, and beneficiary forms reduce the bill (on the order of hundreds of thousands) but do not eliminate it while you remain Illinois residents at death.
| Path | Outcome | Catch |
|---|---|---|
| Stay in Illinois | Pay Illinois estate tax — roughly $300k–$800k depending on bypass use and growth | Trust drafting still worth it to use both $4M exclusions and avoid the high end |
| Change domicile before death | No Illinois estate tax on non-Illinois situs assets (IRAs, most brokerage) | Must actually establish new domicile; Illinois real estate and tangible property in IL still taxed (apportioned on Form 700-Addendum); audit risk if ties to IL remain |
Trust and Roth beneficiary planning is how you optimize within "stay and pay." It is not a substitute for residency choice. If you will not move, the honest plan is: Clayton QTIP + bypass, correct beneficiary forms, then budget for Illinois tax.
States with no estate/inheritance tax on your profile (e.g. Tennessee — no inheritance tax for 2016+ decedents, no trust income tax for 2021+): tn-inheritance-tax-summary, tn-hall-income-tax-repeal-summary. Domicile change requires counsel; do not rely on a vacation home or short stay.
What does not shield Roth (common mistakes)
| Mistake | Why it fails |
|---|---|
| Name bypass trust or QTIP as Roth beneficiary | Roth lands in marital/bypass structure unnecessarily; may break spousal rollover; QTIP brings Roth back into survivor's estate without benefit |
| Name unfunded revocable living trust as Roth beneficiary without see-through drafting | Trust may not qualify as see-through; compressed payout; estate still includes Roth |
| Name estate as beneficiary | Least favorable payout; probate; no stretch |
| Assume Roth is "already tax-free" so beneficiary form does not matter | Estate tax and SECURE Act 10-year compliance still apply |
| Fund bypass with Roth at first death | Wastes income-tax-free character; poor split — bypass should hold non-retirement assets |
Married couple: coordinated playbook (Roth-heavy)
At first death the estate plan should split non-Roth assets (Clayton QTIP / bypass formula per ab-abc-trust-plan.md). Roth accounts pass outside the trust funding formula via beneficiary designation:
1. Primary beneficiary: surviving spouse (spousal rollover).
2. Contingent: child outright, or see-through conduit trust if creditor/spendthrift protection needed.
3. Optional partial contingent: charity on a separate Roth account or percentage split.
4. Do not route Roth through bypass or QTIP sub-trusts.
Roth-heavy implication: most survivor liquidity may be tax-free Roth distributions while Illinois tax planning operates on house, brokerage, and any trad IRA remainder.
Trust as Roth beneficiary (when you want protection)
A trust is not a designated beneficiary, but individuals behind a qualifying see-through trust can be. Requirements (Pub. 590-B): valid trust; irrevocable at death; identifiable beneficiaries; trustee documentation to custodian.
| Trust type | Estate tax | Payout / compliance | Use when |
|---|---|---|---|
| Conduit (see-through) | Roth still in decedent's estate; no estate shield | All IRA/Roth distributions paid out to individuals immediately; 10-year rule measured through individuals | Child needs spendthrift/creditor protection; bloodline trust |
| Accumulation | Same | Harder stretch; trust-level 10-year; undistributed Roth income still tax-free but trust may file 1041 | Rare for Roth; usually worse |
| Testamentary remainder (funded at death from bypass) | Bypass assets already excluded at first death | Trust holds cash/securities from bypass, not Roth | Grandchildren / dynasty; fund with non-Roth bypass remainder |
Estate-tax shielding for heirs at second death: fund dynasty or testamentary trusts from bypass trust remainder (non-Roth), not from Roth beneficiary designation. GST allocation on Form 709 applies to those transfers.
If you stay in Illinois — minimize, not eliminate
1. Clayton QTIP + bypass on house/brokerage at first death; Roth → spouse by beneficiary designation.
2. Roth conversions; pay tax from taxable accounts (shrinks estate, not IL rate).
3. Second death: Roth → Heather (outright) or conduit trust; bypass remainder to bloodline/GST trust.
4. Charitable Roth beneficiary for church bequest (estate deduction, no income tax).
5. Lifetime 529 / annual exclusion gifts — marginal on a Roth-heavy estate.
Beneficiary designation template (discussion draft)
| Account | Primary | Contingent |
|---|---|---|
| Each Roth IRA | Surviving spouse | Heather (outright) or Heather conduit see-through trust; optional church % on separate account |
| Trad IRA (QCD pool) | Surviving spouse | Church or estate residue per QCD plan — do not block QCD mechanics |
| Brokerage / house | RLT / will formula | Bypass + QTIP funding at first death |
Annual checklist
- Beneficiary forms match trust instrument (no bypass/QTIP on Roth).
- RLT funded for house and brokerage.
- Form 700 / 706 filed at first death if bypass/QTIP funded.
- See-through trust documentation delivered to custodian within deadlines after death.
- Revisit after law changes, account openings, or grandchild births.
