IDGT, GRAT, SLAT, QPRT: Advanced Trust Strategies for High-Net-Worth Business Owners

By Hykes Financial Group February 2026 10 min read
Bottom line up front: If your estate is above $5M โ€” or growing toward it โ€” the standard trust toolkit isn't enough. IDGTs, GRATs, SLATs, and QPRTs are the tools that allow serious wealth transfers of $1M, $5M, even $20M+ with little to no gift or estate tax. Here's what each does and when to use it.

Why Standard Planning Isn't Enough Above $5M

A basic revocable living trust avoids probate. A simple irrevocable trust removes assets from your estate. But for business owners whose estates are growing toward โ€” or beyond โ€” the federal exemption, those tools leave enormous value on the table.

The strategies below are designed to transfer large amounts of wealth โ€” sometimes tens of millions of dollars โ€” while consuming minimal or zero gift and estate tax exemption. Each one exploits a different feature of the tax code. None of them are loopholes; they are each explicitly sanctioned by statute or IRS guidance.

The 2026 sunset makes timing critical: the current $13.99M per-person federal exemption is scheduled to drop to approximately $7M after December 31, 2025. Large transfers made before that deadline lock in today's higher exemption. Waiting costs real dollars.

IDGT โ€” Intentionally Defective Grantor Trust

IDGT: The Business Owner's Favorite

The name sounds like a flaw โ€” "defective" โ€” but the defect is intentional and advantageous. An IDGT is:

The power move โ€” installment sale to an IDGT: You sell a business interest (LLC membership units, S-Corp stock) to the IDGT in exchange for a promissory note at the applicable federal rate (AFR). Because the trust is "defective" โ€” treated as you for income tax โ€” the sale produces no capital gains. The business interest appreciates inside the trust. Your estate holds only the note (fixed value). All appreciation above the AFR passes to heirs estate- and income-tax-free.

Ideal for: Business owners planning a sale within 3โ€“7 years, pre-IPO equity, or any asset with high expected appreciation. A $3M business interest sold to an IDGT that later sells for $10M means $7M passes to heirs with zero estate or income tax on the growth.

GRAT โ€” Grantor Retained Annuity Trust

GRAT: The Appreciation Transfer

A GRAT allows you to transfer the appreciation on assets while keeping the underlying value in your estate โ€” and potentially consuming zero gift tax exemption.

Best use: Stock options, private equity interests, real estate, or any asset you expect to significantly outperform the ยง7520 rate (currently 4โ€“5%). A $2M asset that grows to $3.5M during the GRAT term transfers $1.5M in growth to your heirs with no gift tax and no exemption used.

Key risk: You must outlive the GRAT term. If you die during the term, the GRAT assets return to your estate. Shorter terms (2โ€“3 years) reduce this mortality risk. Rolling GRATs โ€” a series of short-term GRATs โ€” are a common mitigation strategy.

SLAT โ€” Spousal Lifetime Access Trust

SLAT: Remove Assets While Keeping Indirect Access

A SLAT solves a problem that stops many business owners from funding irrevocable trusts: the loss of access to those assets.

Ideal for: Married couples with combined estates above $14M who want to use the full individual exemption ($13.99M in 2026) before the sunset, without giving up all access to the assets transferred.

Key risk: Divorce or your spouse's premature death eliminates your indirect access. Reciprocal SLATs โ€” where each spouse creates a SLAT for the other โ€” are sometimes used, but must be structured carefully to avoid IRS reciprocal trust challenges.

QPRT โ€” Qualified Personal Residence Trust

QPRT: Transfer Your Home at a Steep Discount

A QPRT allows you to transfer your primary residence or vacation home to an irrevocable trust while retaining the right to live there for a fixed term โ€” and the gift value is calculated actuarially, not at full fair market value.

Key risk: You must outlive the QPRT term. If you die during the term, the full home value returns to your estate. Also, heirs inherit your original cost basis โ€” no step-up โ€” which creates a capital gains issue if they sell later.

NC-Specific Context

North Carolina does not impose a state gift tax or state estate tax. All gift and estate tax planning for NC residents is driven entirely by federal law. This simplifies the analysis: you only need to worry about one exemption amount and one tax rate.

NC's flat 4.5% income tax rate applies to trust income when the trust is a non-grantor trust with NC situs or NC beneficiaries. For grantor trusts, income flows to your personal return at the same 4.5% NC rate. This is a relatively low state income tax burden compared to states like CA or NY, which makes grantor trust structures slightly less advantageous in NC than they are in high-income-tax states.

The 2026 Sunset: Act Before Year-End

The Tax Cuts and Jobs Act doubled the federal estate and gift tax exemption. That doubling expires December 31, 2025, unless Congress acts. For 2026, the exemption is projected to drop from $13.99M per person to approximately $7M per person ($14M for married couples).

Business owners with estates approaching or above $7M have a narrow window to lock in transfers at the higher exemption. IDGTs and SLATs funded before year-end preserve today's exemption permanently โ€” even after the sunset, transfers already made are not "clawed back."

What we do: These strategies require precise coordination between estate attorney, accountant, and financial advisor. We handle the tax layer โ€” making sure every structure is filed correctly, every trust return (Form 1041 or grantor trust letter) reflects the strategy as designed, and income flows are correctly tracked year over year. Getting the income tax treatment wrong on any of these structures creates problems that take years to unwind.
