How an Irrevocable Trust Can Get a Step-up in Basis
Book a Consultation
You often hear estate planning and wealth management discussed as if they are separate. Attorneys draft documents, and financial professionals manage assets.
In practice, those disciplines rarely come together in a coordinated way. That disconnect is one of the most common reasons family wealth is not preserved or maximized over time.
When structure and strategy are not aligned, opportunities are missed and outcomes fall short of what the plan was designed to achieve.
Lets get into it.
Estate planning and wealth management must operate as a single system.
Estate planning defines structure, while wealth management governs how assets grow and are deployed. When those functions are separated, decisions are made without a shared framework.
That fragmentation leads to inefficiencies. The legal structure may be sound, but the assets are not managed in a way that supports it.
When the two are integrated, planning becomes intentional. Decisions around growth, transfer, and control are made within the same system rather than in isolation.
Tax outcomes, not nominal returns, determine long-term wealth.
Investment performance matters, but taxes ultimately determine what is retained and transferred. The timing of when assets are sold or transferred can be as important as how they perform.
That is where tax basis becomes critical. Gains are measured relative to basis, and that calculation directly affects what is owed when assets are sold.
Over long periods of time, tax treatment can outweigh differences in return. Structure determines how those outcomes are realized.
The step-up in basis is one of the most important wealth-preserving tools.
At death, many assets receive a step-up in basis to their fair market value. That adjustment can eliminate or significantly reduce built-in capital gains.
For appreciated assets such as businesses, real estate, and concentrated positions, this creates a meaningful shift in after-tax value.
Despite its impact, this feature is often underutilized. Planning decisions that ignore basis can reduce the effectiveness of an otherwise strong strategy.
Traditional trust planning often sacrifices basis to achieve control and protection.
Irrevocable trusts provide asset protection, privacy, and governance, but they are typically funded through completed gifts.
Once a gift is complete, the asset is removed from the taxable estate and retains its original basis. That means the opportunity for a step-up is lost.
This creates a perceived tradeoff. Families often believe they must choose between governance and tax efficiency, when in reality the issue is how the structure is designed.
Incomplete gift planning aligns governance with basis preservation.
A gift is only complete when certain rights are fully relinquished. By retaining limited powers, transfers can remain incomplete for tax purposes while still achieving asset protection and control.
In that structure, assets can be held in an irrevocable trust while still being included in the grantor’s estate. That inclusion preserves eligibility for a step-up in basis.
The result is a more coordinated outcome. Protection, privacy, and governance are achieved without forfeiting one of the most valuable tax advantages available.
Durable wealth planning integrates structure, tax strategy, and governance.
Incomplete gift planning is not a single tactic. It is part of a broader system that aligns how assets are held, managed, and transferred over time.
When coordinated properly, gains can be deferred, losses can be managed, and appreciation can still benefit from a step-up at the appropriate time.
At the same time, the trust structure supports family governance, allowing wealth to be treated as an enterprise rather than a series of isolated decisions.
When these elements work together, the outcome is not just preservation, but durability. Wealth compounds more effectively and remains aligned with the family’s long-term intent.
