How Estate Planning Strategies Evolve as Wealth Grows

For many families, estate planning begins with a will and basic documents. As wealth grows, however, planning may need to become more strategic. The focus shifts from simply transferring assets to encompass a broader and longer-term view: protecting wealth, minimizing taxes, and structuring assets so they can support multiple generations and establish a family legacy.

Analysts estimate that roughly $124 trillion will transfer between generations in the U.S. by 2048, representing the largest wealth transfer in history.

For families with complex estates, multiple residences, businesses, and philanthropic ambitions, the estate planning stakes can be high. Research shows that 90% of wealthy families lose their wealth by the third generation, often due to governance failures rather than investment mistakes.

While every family’s situation is unique, estate planning strategies tend to evolve in fairly predictable stages as the family’s wealth increases. Below, we share a framework to illustrate how planning typically progresses and outline the types of strategies families often begin considering as their balance sheet grows.

Building the Planning Foundation: $10M+ Net Worth

When families reach this degree of wealth, they often begin to transition from basic estate documents to a more coordinated structure for managing and transferring wealth.

A revocable living trust commonly becomes the central estate vehicle, allowing assets to pass efficiently and privately while avoiding probate. It becomes especially important to ensure that beneficiary designations on retirement accounts, insurance policies, and investment accounts coordinate with the overall estate plan.

Families at this stage often begin:

• Updating core estate documents (wills, powers of attorney, and healthcare directives)
• Making annual exclusion gifts to children or grandchildren
• Evaluating state estate tax exposure, which can begin at much lower wealth levels than the federal estate tax
• Structuring real estate and investment properties in LLCs for liability protection
• Establishing donor-advised funds for charitable giving
• Evaluating Qualified Small Business Stock (QSBS) planning, including transferring shares to trusts or family members before a liquidity event to potentially multiply the capital gains exclusion

These steps help create a strong planning foundation that allows more advanced strategies to be implemented as wealth grows.

Estate Tax Planning: $25M+ Net Worth

As family wealth approaches $25 million, estate taxes become a primary concern. Planning often shifts toward reducing the taxable estate and transferring future appreciation outside the estate.

Families at this stage often begin using lifetime exemption gifting, transferring assets to heirs or trusts while utilizing their federal estate and gift tax exemption. Moving appreciating assets earlier can significantly reduce future estate taxes.

Grantor Retained Annuity Trusts (GRATs) are also a commonly used tool for concentrated stock positions or business interests expected to appreciate significantly. If the assets outperform IRS assumptions, the excess growth can transfer to heirs with little or no gift tax.

Another frequently employed strategy is the use of an Irrevocable Life Insurance Trust (ILIT). Life insurance owned by an ILIT can provide tax-free liquidity to help cover estate taxes without requiring the sale of family businesses, real estate, or investment portfolios.

Families may also explore intrafamily loans, which allow individuals to lend money to children, other family members, or friends using IRS Applicable Federal Rates (AFRs). Because these rates are typically much lower than commercial borrowing rates, this can be an effective way to provide financial support, with the option to further enhance the strategy by using annual exclusion gifts to gradually reduce the loan balance over time.

At this level, families often begin introducing early governance practices as well. Annual family meetings, financial education for heirs, and participation in philanthropic activities can help prepare younger generations to understand and responsibly steward family wealth. These governance habits, introduced early, often become essential components of long-term wealth preservation.

Future Appreciation Planning: $50M+ Net Worth

As a family’s wealth approaches or exceeds $50 million, they often focus their planning strategies on moving substantial future appreciation outside the estate while maintaining flexibility for the family.

This focus requires introducing some more advanced strategies.

Generation-Skipping Transfer (GST) Trusts
These trusts are structured so that the grantor’s GST exemption is allocated to the trust when it is created, allowing assets to pass to future generations without additional estate or generation-skipping taxes.

Spousal Lifetime Access Trusts (SLATs)
With this structure, one spouse transfers assets to a trust benefiting the other spouse and future heirs. This removes assets from the taxable estate while still allowing indirect access through the beneficiary spouse.

Intentionally Defective Grantor Trusts (IDGTs)
IDGTs are commonly used in advanced estate planning to shift future asset growth outside the taxable estate while allowing the grantor to continue paying income taxes on the trust’s earnings. This strategy can further enhance the long-term transfer of wealth to future generations.

Zeroed Out and Short-Term Grantor Retained Annuity Trusts (GRATs)
GRATs may continue to play an important role even after a family has used most or all of their lifetime estate and gift tax exemptions. Many families employ a structure called the “zeroed-out GRAT,” in which the annuity payments are calibrated so that the initial taxable gift is close to zero. If the assets in the GRAT appreciate faster than the IRS assumed rate, the excess growth passes to heirs at the end of the term with little or no additional gift tax. Alternatively, some families use a series of short-term GRATs to repeatedly shift appreciation from concentrated stock positions or other appreciating assets outside the taxable estate.

Charitable remainder trusts (CRATs and CRUTs)
Philanthropy often becomes more sophisticated at this stage. Charitable Remainder Annuity Trusts and Charitable Remainder Unitrusts allow families to contribute highly appreciated assets, sell them within the trust without immediate capital gains tax, and receive an income stream for a period of time. At the end of the trust term, the remaining assets pass to charity.

At this stage, philanthropy may evolve into a more formal legacy strategy as families seek to engage younger family members in governance, decision-making, and the broader purpose behind the family’s wealth.

Multi-Generational Capital Structures: $100M+ Net Worth

At these ultra-high net worth levels of wealth, families often begin thinking about their assets less as individual investments and more as a pool of family capital that must be organized and managed across generations. Central at this stage are structures designed for multi-generational planning.

Dynasty trusts
Dynasty trusts are intended to last for multiple generations and allow assets to grow outside the taxable estate while providing long-term asset protection. When structured properly, these trusts can allow family capital to compound for children, grandchildren, and future generations without being subject to estate taxes at each generational transfer.

Family LLCs or holding companies
Families often establish centralized ownership structures that consolidate investment portfolios, real estate, and private business interests under a single family entity. These structures can simplify management, provide liability protection, and facilitate gradual ownership transfers across generations.

Private foundations
Families with significant philanthropic goals may consider establishing a private foundation to support long-term charitable initiatives. Foundations allow families to create a structured giving platform, support causes over many years, and involve multiple generations in charitable decision-making.

This stage is marked by a distinct shift in focus toward creating durable systems that coordinate investment management, governance, tax strategy, and generational leadership.

When Families Begin Considering the Next Stage of Planning

Delineations from stage to stage are not rigid thresholds; families often begin exploring the next stage of planning when the need arises rather than at a particular level of affluence. Certain events are common triggers:

• The sale of a business or liquidity event
• A concentrated stock position that has appreciated significantly
• Real estate or private investments that are expected to grow meaningfully
• The birth of grandchildren or expanding family dynamics
• Anticipated changes to estate tax law

In many cases, planning is likely to be most effective before assets experience substantial growth, allowing more appreciation to occur outside the taxable estate.

For this reason, estate planning is best viewed as an ongoing process that evolves alongside a family’s balance sheet and long-term goals.

While tax planning and legal structures are essential, one of the most important—and frequently overlooked—components of multigenerational wealth preservation is family governance. Many families devote significant effort to structuring trusts and investment portfolios but spend far less time preparing the next generation to manage the responsibilities associated with wealth.

Families that successfully preserve wealth over multiple generations often establish clear governance systems that support communication, leadership development, and shared decision-making. These may include family councils responsible for guiding long-term decisions and resolving disputes, as well as written family constitutions that articulate shared values, investment philosophy, and expectations for participation in family enterprises.

Equally important is next-generation education. Many families invest significant time in helping younger members develop financial literacy, investment knowledge, and an understanding of fiduciary responsibility. These efforts help ensure that future generations view wealth not simply as an inheritance, but as a resource requiring stewardship.

The Coldstream Perspective

Estate planning is not a single transaction. As wealth grows, strategies evolve and need to become more sophisticated.

Family objectives extend beyond just transferring assets efficiently to building a durable framework that protects wealth, aligns with family values, and supports future generations.

At Coldstream, we approach estate planning as part of a broader wealth strategy—integrating tax planning, estate structuring, philanthropic planning, and long-term financial guidance into a coordinated approach that evolves alongside a family’s wealth. When executed thoughtfully and strategically, estate planning strategy becomes more than taxes and trusts: it becomes a blueprint for multigenerational opportunity, stewardship, and impact.
