The Role of Step-up in Basis in Multi-Generational Wealth Planning

By Team Seneschal

Families who care about passing wealth to the next generation often focus on portfolio returns. Taxes matter just as much. One rule in the tax code plays a significant role in how much your heirs keep. It is known as step-up in basis. It resets the tax value of assets at death. This simple reset can eliminate years of taxable gains.

How Basis Works

Your basis is usually what you paid for an asset. If you bought stock for one price and it increased in value over time, your basis remains tied to the original price you paid. When you sell, you pay tax on the gain above that basis.

The long-term capital gains tax rate can reach twenty percent for high earners. That tax applies when you sell. Some families also owe the 3.8% net investment income tax.

These taxes make it expensive to sell assets with significant, unrealized gains.

How Step-Up Changes Everything

The tax code allows most inherited assets to receive a step-up in value to the fair market value at the time of death. When this happens, the old gains disappear. If your heirs sell the asset soon after they inherit it, they may owe little or no capital gains tax.

This rule can help with appreciated real estate, long-held stock, or a business that has increased in value. It also makes step-up a powerful tool in multi-generational planning.

When Gifting Still Makes Sense

Gifting can be a strategic financial decision that plays a significant role in estate planning and tax management. One of the primary advantages of gifting is its potential to reduce the taxable value of an estate, especially if you anticipate your estate will exceed the estate tax exemption threshold.

By making lifetime gifts, you effectively transfer assets to your beneficiaries while they are still alive. Doing so decreases the size of your taxable estate and allows those assets to appreciate outside of your estate.

Gifting can be particularly advantageous for younger family members who may be in lower tax brackets. By gifting assets to them, you can shift the income generated, potentially reducing the overall tax burden on the income earned.

This strategy leverages the difference in tax brackets, maximizes the benefit of the gifted assets, and allows the recipients to enjoy the financial advantages at an earlier stage in their lives.

Gifting can have emotional benefits. It allows you to witness the positive impact your generosity has on your loved ones. It can help them with significant life expenses, like education, home purchases, or starting a business.

Overall, gifting is a versatile tool that can offer financial and personal benefits. The key is comparing two taxes. One is the estate tax your estate may face if you keep the asset. The other is the potential capital gains tax your heirs may incur if they sell the asset later. However, when a stepped-up basis is applicable, that can eliminate the tax on appreciation that occurred during your lifetime.

Thoughtful planning involves comparing both scenarios.

How Community Property Affects Step-Up

Some states treat property acquired during marriage as community property. When one spouse dies, both halves of community property typically receive a full step-up in basis. This makes community property states especially powerful for couples with appreciated assets.

If you move from one state to another, the community property character may follow the assets. Many couples intentionally structure their holdings to retain the full step-up benefit.

Common Mistakes Families Make

Families often give up tax benefits without realizing it.

  • Selling A Home or Rental Property Late in Life
    This can result in a tax bill that would have been eliminated upon death.
  • Gifting Appreciated Assets Without Thinking About Basis.
    Integrating investing and estate planning is vital to avoid unnecessary tax burdens. Ignoring the connection can result in incurring avoidable taxes.
  • How Trusts Interact with Step-Up
    Revocable living trusts usually receive the same step-up as assets held in your own name. Irrevocable trusts work differently. Assets already moved into an irrevocable trust may not receive a step-up unless the trust is drafted to allow it.

Your long-term plan should align with the trust structure that supports your goals.

How High-Net-Worth Families Use Step-Up

Families with long time horizons often follow a simple rule. They keep assets with significant unrealized gains and gift assets with little appreciation.

They also use tax-efficient strategies to manage gains.

They may hold concentrated stock that would trigger too much tax if sold. They may also hold income-producing real estate. Step-up wipes out the appreciation at death, giving the next generation a clean slate.

These choices are not about avoiding taxes. They are about understanding the rules and using them wisely.

Why Step-Up Remains Central to Long-Term Planning

A step-up gives your heirs a fresh start. It reduces the tax burden across generations. You do not need complicated structures to use it. You need awareness, intention, and coordination between your investments and your estate plan.

When you combine those pieces, step-up becomes one of the most practical tools for preserving wealth for future generations.
