How to Invest $4 Million: What Changes at the $4M Tier
Going from $3M to $4M is the tier where several planning thresholds converge simultaneously. Illinois estate tax exposure becomes real for the first time. Grantor Retained Annuity Trusts (GRATs) — an estate freeze strategy worth ignoring at lower levels — now have a favorable cost-benefit for state-estate-tax residents. The qualified purchaser threshold ($5M) is one million away, changing how you think about alternatives positioning. And with $2M+ in pre-tax accounts, the first projected RMD at age 73 or 75 can easily exceed $250,000/year — making Roth conversion planning more time-sensitive than any earlier tier.
This guide starts where the $3M guide ends. It doesn't repeat the foundation — Roth mechanics, IRMAA tiers, direct indexing basics, or estate planning fundamentals — but focuses on what is genuinely different when the fourth million lands. Follow the internal links for full mechanics and calculators on each topic.
The Wealth Tier Map: $1M Through $5M+
How the key planning dimensions evolve across the wealth tiers:
| Planning Dimension | $1M | $2M | $3M | $4M | $5M+ |
|---|---|---|---|---|---|
| State estate tax | Below threshold in most states (OR is exception) | OR, RI, MA exposed; WA/MN borderline | OR, RI, MA, WA/MN definitely exposed | All above + IL exposed when total estate (portfolio + home + life ins.) crosses $4M | Irrevocable trust structures (SLAT, GRAT, ILIT) fully justified in most affected states |
| GRAT strategy | Not worth setup cost | Marginal — borderline in OR/MA/RI | Worth considering in OR/MA/RI; legal cost ~$3K–$6K | Clear positive ROI in OR, MA, RI, WA, MN, IL for growth assets; rolling 2-year GRATs for appreciated equity holdings | Core tool alongside SLATs, ILITs; ongoing trust program |
| Annual gifting | $19K–$38K/yr; small % of portfolio | $38K–$76K/yr; meaningful in estate-tax states | $76K–$152K/yr; clear ROI vs state tax | $152,000+/yr (couple to 4 beneficiaries); removes $1.52M+ over a decade | Core estate reduction: 529 superfunding + annual exclusions + GRAT programs |
| Qualified purchaser horizon | Accredited investor only | Accredited investor; $3M away from QP | $2M away from QP threshold | $1M away — plan alternatives positioning with QP threshold in mind; avoid 5-yr lock-ups expiring after $5M | QP unlocks Section 3(c)(7) vehicles: institutional hedge funds, PE mega-funds, certain credit vehicles |
| Annual advisor fee at 1% AUM | $10,000/yr | $20,000/yr | $30,000/yr | $40,000/yr; flat-fee or 0.4–0.5% structures win decisively | $50,000+/yr; fee renegotiation is required at this level |
| LTC self-insurance | Cannot self-insure without damage | Borderline; hybrid policies worth evaluating | Can self-insure median event; tail risk still significant | Median event ($330K) = 8.25% of $4M — clear self-insure territory; insurance only for tail risk preference | Self-insure is standard; no financial argument for traditional LTC insurance |

State Estate Tax at $4M: Illinois Joins the List
The federal estate and gift tax exemption is $15M per individual under the OBBBA — permanently, with no 2026 sunset.1 So $4M creates zero federal estate tax exposure. But state estate taxes operate on completely different exemptions, and at $4M, a new state becomes relevant.
Illinois joins the list at the $4M tier. Illinois taxes estates above $4,000,000 at graduated rates of 0.8–16%.2 A $4M investable portfolio doesn't automatically trip the threshold — your total taxable estate includes the portfolio plus home equity, life insurance death benefits, and business interests. A $4M investor with a $700K home and $400K in life insurance death benefit has a gross estate of approximately $5.1M — well into Illinois territory.
| State | 2026 Exemption | Rate Range | $4M Portfolio + $700K Home = $4.7M Gross Estate |
|---|---|---|---|
| Oregon | $1,000,000 | 10–16% | $3.7M taxable → estimated $350K–$440K tax |
| Rhode Island | $1,838,056 | 0.8–16% | $2.86M taxable → estimated $230K–$290K tax |
| Massachusetts | $2,000,000 (cliff) | 0.8–16% on entire estate | Full $4.7M estate taxed → estimated $330K–$400K tax |
| Washington | $3,000,000 | 10–20% | $1.7M taxable → estimated $170K–$260K tax |
| Minnesota | $3,000,000 | 13–16% | $1.7M taxable → estimated $195K–$245K tax |
| Illinois — NEW at $4M | $4,000,000 | 0.8–16% | $700K taxable → estimated $56K–$90K tax; but add retirement accounts and life insurance → taxable estate grows significantly |
The Illinois situation requires a full estate inventory. Unlike investment accounts, traditional IRA and 401k balances are included in the gross estate for Illinois estate tax purposes — even though they're excluded from federal estate calculations during lifetime. An Illinois resident with $4M in investments, $700K in home equity, $300K in life insurance death benefit, and $800K in traditional IRA balances has a gross estate of $5.8M — $1.8M above the $4M exemption. At graduated rates, the Illinois estate tax on that $1.8M excess could be $140K–$200K depending on the taxable estate bracket structure.
The planning response at $4M in Illinois: start a systematic gifting program now (before the estate grows further), model whether a revocable trust with marital credit-shelter provisions reduces IL exposure, and have an estate attorney evaluate whether a GRAT makes sense for growth assets (see next section).
GRAT Strategy: Freeze Your Estate at $4M
A Grantor Retained Annuity Trust (GRAT) is an estate planning tool that moves future asset appreciation out of your estate — essentially estate-tax-free — while you continue to receive an annual annuity payment from the trust for the term of the GRAT. At $3M it's worth considering in high-tax states; at $4M in any of the six affected states, it's worth a real conversation with an estate attorney.
How a zeroed-out GRAT works
The mechanics:
- You transfer appreciated assets (equity portfolio, business interest, RSU blocks) to the GRAT.
- You receive an annuity payment back each year for the trust term (typically 2–10 years).
- The annuity is sized using the IRS Section 7520 rate — currently 5.00% for June 2026 per IRS Rev. Rul. 2026-93 — so the present value of your retained annuity equals the assets transferred. This is the "zeroed-out" structure: the taxable gift value at trust creation is approximately $0.
- Any appreciation in the trust assets above the 5.00% IRS hurdle rate passes to your heirs at the end of the term — completely outside your estate for state estate tax purposes.
Example: You put $500,000 in growth-oriented equities into a 2-year GRAT. The IRS assumes those assets will earn the 5.00% §7520 hurdle. If they earn 12% instead, approximately $70,000 in excess appreciation passes to your heirs estate-tax-free at the end of year two — with a $0 taxable gift at inception.
Rolling 2-year GRATs at $4M
For investors with ongoing appreciated equity positions — especially those with concentrated stock, continuing RSU vesting, or a taxable equity portfolio that's growing — a "rolling GRAT" strategy creates a systematic estate freeze. You fund a new 2-year GRAT each year with that year's appreciated block. The prior GRAT matures and returns principal as an annuity; the new GRAT captures the next year's appreciation.
At $4M in a state with an estate tax exemption below your total estate, this is a meaningful strategy. The legal cost of a GRAT is $3,000–$6,000 per trust (ongoing annual rolling GRATs cost less after the first, as attorneys reuse the basic template). Against an estimated $140K–$440K state estate tax bill depending on the state, even modest appreciation capture has a very favorable cost-benefit.
Critical caveat: the GRAT fails entirely if you die during the trust term — assets come back into your estate as if the GRAT never happened. For this reason, life insurance is sometimes paired with GRAT strategies to cover the estate tax exposure that would apply if the grantor dies mid-term. This is an attorney-CPA coordination question, not a DIY decision. See estate planning guide and revocable trust guide for the foundational trust mechanics before evaluating GRATs.
Annual Gifting at Scale: $152,000+/Year Out of Your Estate
The 2026 annual gift tax exclusion is $19,000 per recipient, per donor.4 A married couple can give $38,000 to each recipient through gift-splitting. With four beneficiaries (two adult children and their spouses), the math is:
- $19,000 × 2 donors × 4 recipients = $152,000 per year
- Over 10 years: $1,520,000 removed from your estate permanently
- Investment growth on gifted amounts accrues in the recipients' accounts, not yours
At $4M, $152,000/year is 3.8% of the portfolio — a meaningful annual transfer. For a 55-year-old investor in an estate-tax state, starting this program now creates cumulative savings that compound over 20+ years of retirement. The comparison: $1.52M removed through gifting × 7% growth over 15 years in the recipient's hands = approximately $4.2M in combined estate + investment benefit — at zero gift tax cost and no legal fees beyond a gifting log.
Gifting strategy: appreciated stock transferred directly to recipients is the most tax-efficient form. The recipient inherits your cost basis (so they'll owe capital gains on sale), but the FMV at time of gift is the amount that leaves your estate. A $100,000 block of long-held equity with $10,000 basis transfers $100,000 out of your estate while you avoid the capital gains tax entirely — the recipient pays only if and when they sell. The concentrated stock guide covers this in the context of managing large single-position exposures. Compare gifting vs. DAF donation for the same appreciated block: charitable giving guide.
Roth Conversion Urgency Intensifies at $4M
If 50–75% of your $4M is in pre-tax accounts ($2M–$3M traditional IRA and 401k), the trajectory toward large forced distributions is clear. At 7% annual growth from age 56 to age 75 (the RMD start age for anyone born 1960 or later5), $2.5M grows to approximately $8.5M. First-year RMD using the Uniform Lifetime Table divisor of 27.4: $310,000. Add Social Security income ($35,000–$55,000 per person annually in a typical $4M household scenario) and the total taxable income in year one of RMDs likely exceeds $380,000–$420,000 — firmly in the 35% bracket and triggering IRMAA tier 3 or 4 simultaneously.
The Roth conversion opportunity: at $4M, a couple in the 24% bracket (up to $403,600 in 20266) with $250K in ordinary income has $150,000 of 24% conversion room before hitting the 32% bracket. Converting at 24% to avoid future distributions at 35–37% plus $10,000–$15,000/year in IRMAA surcharges is favorable arithmetic in most scenarios.

Direct Indexing at Full Capacity
A $4M investor with a typical account mix likely holds $1.5M–$2.5M in taxable equities — the tier where direct indexing operates at full institutional capacity. The annual tax alpha at scale:
- 1.0–1.5% harvest rate on $2M in taxable equities = $20,000–$30,000/year in realized losses
- At a 15–18.8% LTCG + NIIT rate, that's $3,000–$5,640/year in deferred tax savings — compounding
- Over 20 years at 7% portfolio growth, $4,500/year in tax deferral compounds to approximately $190,000 in additional terminal portfolio value versus an ETF-equivalent portfolio
At $4M, all institutional direct indexing programs are accessible: Parametric, Aperio, Vanguard Personalized Indexing, Schwab Personalized Indexing, and several RIA-administered custom programs. The incremental fee over passive ETF management typically runs 0.15–0.35%/year on the direct-indexed allocation. On $2M, that's $3,000–$7,000/year — still below the tax alpha in active-market years. Full analysis, provider comparison, and break-even calculator: direct indexing guide →.
The Qualified Purchaser Horizon: Planning Ahead for $5M
At $5M in investable assets, an investor becomes a "qualified purchaser" under Section 2(a)(51) of the Investment Company Act of 1940. This unlocks a different category of investment vehicle — Section 3(c)(7) funds — that are closed to accredited investors under $5M. These include institutional hedge funds with broader strategies, certain private equity mega-funds, and credit vehicles with different fee structures than the retail-wrapper alternatives available at $4M.
At $4M you're not a qualified purchaser yet. But the planning implication is relevant now: avoid illiquid investments with 5-year lock-ups that will mature in or after your $5M window. A 5-year private equity fund entered at $4M locks you out of redeploying to qualified purchaser vehicles until well past $5M. Instead, favor shorter-duration or more liquid alternatives at $4M — private credit with quarterly redemptions, interval funds with monthly liquidity, or direct real estate syndications with 2–3 year hold periods — so capital is available when qualified purchaser status is reached.
The alternatives allocation at $4M (10–15% = $400K–$600K) can still access institutional minimums in the accredited-investor universe. Private credit direct lending funds, core-plus real estate, and growth equity vehicles all have $250K–$500K institutional minimums that work at $4M. Full framework and risk/liquidity table: alternative investments guide →.
The $40,000/Year Fee Question
A 1% AUM fee at $4M costs $40,000/year. The compound drag between a 1% advisor and a 0.5% fee-only RIA at $4M, over 20 years at 7% gross return, is approximately $700,000 in terminal portfolio value — from the fee differential alone.
Well-run fee-only RIAs who specialize in $3M–$5M clients typically charge 0.4–0.65% on AUM, or flat annual retainers of $15,000–$25,000 for comprehensive planning. At $4M, the flat fee almost always wins: planning complexity at $4M (state estate tax modeling, GRAT evaluation, Roth conversion program, IRMAA optimization, direct indexing, alternatives positioning toward QP status) is nearly identical to $6M complexity — but AUM-based pricing charges 50% more. Flat fees price the work, not the account balance.

LTC Self-Insurance: Decided at $4M
The median long-term care need is approximately 2.5 years in a nursing home at $10,965/month in 2026 — roughly $330,000.7 At $4M, that's 8.25% of your portfolio. You can absorb this event without material plan damage. The self-insurance case is clear for the median event at $4M.
The honest caveat is the same as at $3M: 22% of people who need care require it for 5 or more years. A 5-year nursing home stay in 2026 costs $660,000+, and with 3% annual cost inflation, a 70-year-old entering care in 2030 might pay $745,000+ for a 5-year stay. At $4M, that's 16–19% of the portfolio — painful but survivable if the rest of the plan is intact. Most $4M investors in good health without specific family LTC history reasonably self-insure at this level, but it should be a deliberate decision, not a default. Full decision framework and break-even calculator: LTC guide →.
Summary: The $4M Priority Stack
In rough priority order for most investors at $4M:
- State estate tax assessment + gifting program — If you live in Oregon, Massachusetts, Rhode Island, Washington, Minnesota, or Illinois, quantify your gross estate (not just investable assets), estimate the tax, and start the $152K+/year gifting program. In OR/MA/RI/WA, start a GRAT conversation with an estate attorney. This is the single highest-ROI new item at $4M vs. $3M for affected-state residents.
- GRAT evaluation — For residents of estate-tax states with appreciated growth assets, get one attorney consultation on whether a rolling 2-year GRAT program makes sense for your specific situation. Legal cost is $3K–$6K; potential state estate tax savings over 10 years can be $70K–$400K+.
- Roth conversion program — With $2M+ in pre-tax accounts, projected first RMD at 73/75 exceeds $200K–$310K before Social Security. The arithmetic of converting at 24% now vs. distributing at 35–37% in retirement is compelling. Model against IRMAA tier boundaries annually. Roth conversion calculator →
- Direct indexing at full capacity — In taxable accounts above $1M, the institutional direct indexing programs available at $4M generate $3K–$6K+/year in compounding tax deferral. This is likely already in place from the $3M tier but worth auditing the program structure and harvest rate. Direct indexing guide →
- Advisor fee renegotiation or switch — $40K/year at 1% AUM. At this tier, 0.5% or flat $18K–$25K flat retainer pricing is available and appropriate. The 20-year compounding gap is $700K. Fee impact calculator →
- Alternatives positioning with QP horizon in mind — Structure the current 10–15% alternatives allocation for liquidity at $5M. Avoid 5-year lockups. Favor private credit with quarterly redemption or shorter PE vehicles. Alternatives guide →
- LTC decision: finalize self-insurance stance — Make the explicit choice: self-insure (with a portfolio earmark), buy a hybrid policy, or maintain traditional LTC coverage. At $4M, continuing to defer the decision is a decision by default — and not necessarily the right one. LTC break-even calculator →
The fastest path to coordinating all of this: get matched with a fee-only advisor who specializes in the $4M–$5M transition.
