Tax Strategy

What tax strategy actually is

For ordinary households, tax is an annual event. Gather documents, file, settle. For a household with meaningful capital (private businesses, concentrated equity, real estate, or a liquid portfolio above roughly $10M), tax is an architecture instead of an event. The architecture is a set of decisions about where income is earned, which entities hold it, how gains are characterized, and when they are realized. These decisions interact across decades, and getting them approximately right matters more than any individual tactical choice.

The common mistake at this level is treating tax as the advisor’s problem. Competent counsel can execute any vehicle precisely. They cannot replace the principal’s understanding of how the pieces fit together. In most plans that hold up over decades, the principal knows the tax structure better than the accountant knows the overall picture of the household.

The order in which levers matter

The higher-impact levers below sit structurally upstream of the lower-impact ones. Tactical moves without architecture produce fractional gains.

Residency and domicile. State, province, or country of residency is usually the largest single lever. The difference between California and Florida adds up over a decade. The difference between a high-tax home country and a zero-tax jurisdiction is several times larger. Residency is also the easiest lever to lose through sloppy execution, because audits chase facts rather than paperwork.

Entity structure. How a business is owned (S-corp, C-corp, LLC, partnership, holding company) determines the character of income, distributions, and eventual sale proceeds for years. The right structure at founding is often wrong later, and restructuring before a sale is routine but rarely cheap.

Character of income. Long-term capital gains, qualified dividends, tax-exempt interest, passive losses, and ordinary income are taxed differently. Portfolios that never address character pay a premium for the same pre-tax return.

Timing. Match realization events to low-income or high-charitable years, or to planned liquidity windows. Bunch deductions. Defer gains until a lower-rate period. The calendar matters more than most advisors plan for.

Basis management. For concentrated positions, the difference between a cost basis of $0 and a stepped-up basis at fair market value is, at the margin, the entire capital gains bill. Step-up at death is one of the largest single-event tax breaks in most jurisdictions.

Trust and ownership structure. Non-grantor trusts, IDGTs, GRATs, and family partnerships shift future appreciation out of the taxable estate while preserving access and some level of control. None of these does useful work on its own. They are only effective inside a coherent plan.

Specific vehicles and elections. Exchange funds, QSBS elections, 1031 exchanges, 1202 qualifications, 83(b) elections, Opportunity Zones, charitable vehicles. Specific tools matter, but they come last in the sequence, not first.

The vehicles that actually do the work

Grantor retained annuity trusts (GRATs). A low-cost transfer vehicle for appreciating assets. The grantor retains an annuity stream roughly equal to the asset’s value plus a statutory rate. Everything that grows above the rate passes to beneficiaries tax-free. Short-term rolling GRATs are the workhorse pattern for pre-IPO and pre-liquidity founders.

Intentionally defective grantor trusts (IDGTs). A trust the grantor is treated as owning for income tax purposes but not for estate tax. Sales to an IDGT move appreciating assets out of the estate while the grantor continues to pay the income tax, which is itself an additional tax-free gift to the trust. The IRS has challenged specific variations, but the core structure has held.

Dynasty trusts. Long-duration trusts, perpetual or multi-century in jurisdictions that permit, designed to keep wealth outside the taxable estate across successive generations. Situs matters. South Dakota, Delaware, Nevada, and New Hampshire dominate US dynasty planning; Jersey and Guernsey structures dominate European and international ones.

Spousal lifetime access trusts (SLATs). An irrevocable trust for the benefit of a spouse that removes the settled assets from the combined estate while preserving some access. Paired SLATs require careful drafting to avoid reciprocal-trust doctrine issues.

Exchange funds. Swap concentrated single-stock positions into a diversified pool without triggering immediate capital gains. The cost is a seven-year holding period and a qualifying real estate sleeve. The product has widened significantly in the last 24 months as minimums dropped.

Charitable remainder trusts (CRTs) and charitable lead trusts (CLTs). Split-interest vehicles that combine philanthropic intent with tax efficiency. CRTs move appreciated assets into a tax-exempt vehicle in exchange for an income stream; CLTs do the inverse. Both are specialized tools that reward careful structuring.

Donor-advised funds (DAFs). The simplest charitable vehicle. Immediate deduction on funding, no annual distribution requirement, low ongoing administrative cost. The right default for households with episodic giving and appreciated securities to donate.

1031 exchanges (US) and equivalents. Like-kind exchanges in real estate defer capital gains indefinitely. The toolkit has narrowed post-TCJA in the US, but it still does real work for serious real estate holders.

Where most households leak

Sentimental holds. A founder or executive holds concentrated stock in the company they built long past the point where doing so is rational. The opportunity cost in foregone diversification routinely runs into seven, eight, or nine figures. The emotional reason is usually easy to name. The financial cost is not visible until it has already compounded.

Legacy entity structures. A household built a complex set of entities (trusts, LLCs, holding companies) for a specific state, business, or life circumstance that no longer applies. The ongoing compliance cost, plus the tax leakage from structure that no longer fits, often runs into the hundreds of thousands per year without anyone naming it.

Advisor fragmentation. A CPA, an estate attorney, a wealth manager, and a business lawyer who have never been in the same room. Each is individually competent. No one is responsible for the whole picture. This is the most common source of material leakage in households above $25M.

Uncaptured losses. Portfolios that never harvest losses, or that harvest inefficiently by selling losing positions and immediately replacing them in ways that violate wash-sale rules. Direct indexing has made harvesting far cheaper to execute with precision. Most households still haven’t moved to it.

Philanthropic intent separated from the vehicle. Families that give from ordinary income rather than appreciated securities pay their full marginal rate on a gift that could have been made at zero cost of basis. The math is almost always visible in their own tax returns. The behavior changes less often than you would expect.

Location of assets. Tax-inefficient assets (high-turnover funds, REITs, taxable bonds) held in taxable accounts while tax-efficient assets sit in tax-deferred wrappers. Asset location is a one-time setup that pays out every year it isn’t fixed.

Advanced moves, and when they fit

None of these is a starter move. Each fits a narrow range of UHNW circumstances, and each requires a specialist who has executed the same structure cleanly before.

Qualified Small Business Stock (QSBS / Section 1202). Under US federal tax law, founders of qualifying C-corporations can exclude up to $10M (or 10x basis, whichever is greater) of capital gains on sale, subject to a five-year holding period and specific entity criteria. Multi-generational QSBS stacking, through gifts to family members and to non-grantor trusts, can multiply the exclusion by a factor of three, four, or more depending on family size.

Opportunity Zone investments. A US vehicle for deferring and partially eliminating capital gains by investing in designated low-income census tracts through a Qualified Opportunity Fund. Program specifics are jurisdiction-specific and time-sensitive; the window for meaningful basis step-up has narrowed.

Captive insurance companies. For families with genuine insurable risks (typically operating-business principals), micro-captives and larger captives can convert insurable exposures into tax-efficient structures. The IRS has been aggressive on abusive small captives. The structures that still hold up on audit are narrower than they were a decade ago.

Private placement life insurance (PPLI). A tax-efficient wrapper for investment assets, particularly useful for households with significant illiquid or hedge fund exposures that would otherwise accumulate tax drag. Expensive to set up. Substantive ongoing attention required. Typically appropriate at $25M+.

Basis-shifting through family entities. Partnerships and family limited partnerships permit specific elections (704(c), 754) that reallocate basis inside the entity in tax-favored ways. Aggressive applications are closely watched. Conservative applications still work.

Intentionally defective beneficiary trusts (IDBTs) and dynasty-plus-SLAT combinations. For households building multigenerational structures, the interaction between vehicles matters more than the choice of any individual one. A plan that reads like a catalog of instruments is usually weaker than one that reads like an architecture.

How to tell if your tax plan is working

The 10-year test. Can you sketch, on a napkin, what your effective tax rate will be in ten years under current policy, and which structural decisions drive it? If the answer is no, you have an accountant. You don’t yet have a tax plan.

The single-advisor test. Does at least one person see every piece of the plan (trust, entity, portfolio, charitable, residency), and have authority to surface conflicts between them? If no one owns the full picture, fragmentation cost is almost always larger than the benefit of any one vehicle.

The calendar test. Are meaningful decisions calendar-driven (year-end harvesting, pre-liquidity structuring, residency timing) rather than event-driven (reacting after the change has already happened)? The households that keep more of what they earn do the work ahead of the trigger, not after it.

Where to go deeper

The technical work belongs with specialists. The judgment calls (when to restructure, which advisor to trust, whether a specific vehicle is worth the complexity) are usually better in peer groups than in one-to-one advisor conversations. TIGER 21, Long Angle, and a handful of founder-specific communities surface case studies from members who have worked through the same decisions.
