Tennessee Community Property Trust: The Double Step-Up Strategy

Tennessee is a common-law property state, but in 2010 the legislature did something unusual — it passed the Tennessee Community Property Trust Act. This law lets married couples voluntarily convert their separate or jointly held assets into community property inside a trust, unlocking a tax benefit that only community property states normally offer: a full double step-up in cost basis when the first spouse dies.

For couples holding appreciated assets like real estate, stocks, or business interests, the capital gains savings can be substantial. Here is how it works and who it actually benefits.

What the Double Step-Up Means

In a standard common-law state, when one spouse dies, only the deceased spouse's half of jointly owned property receives a stepped-up cost basis (adjusted to current fair market value). The surviving spouse's half retains the original purchase price as its basis.

Under Internal Revenue Code Section 1014(b)(6), community property receives a step-up on both halves — the deceased spouse's share and the surviving spouse's share. If you bought a home for $200,000 that is now worth $600,000, both halves reset to $600,000 at death. The surviving spouse can sell immediately with zero capital gains tax.

Without a Community Property Trust, the surviving spouse's half keeps the $100,000 original basis, creating $200,000 in taxable gains if they sell.

How Tennessee's Community Property Trust Works

The Tennessee Community Property Trust Act (T.C.A. Section 35-17-101 et seq.) allows married couples to create a joint revocable trust and elect community property treatment for any assets transferred into it.

Key structural requirements:

• Both spouses must consent in writing to the community property election
• At least one trustee must be a qualified Tennessee trustee — either a Tennessee resident individual or a bank or trust company authorized to do business in Tennessee
• The trust agreement must contain a prominent notice (required in ALL CAPS under the statute) that community property classification may affect property division in the event of divorce
• The trust must be revocable — either spouse can withdraw their contribution or terminate the trust at any time

The trust does not change how assets are managed day-to-day. You and your spouse retain full control. The election simply reclassifies the assets for federal income tax purposes.

Who Actually Benefits

The Community Property Trust is not for everyone. It delivers meaningful value in specific scenarios:

Couples with highly appreciated real estate. If your Tennessee home or investment property has gained $200,000 or more in value, the double step-up eliminates what could be $30,000 to $50,000 in federal capital gains taxes for the surviving spouse.

Couples with concentrated stock positions. Long-held stock portfolios with large embedded gains benefit significantly. The surviving spouse inherits with a full basis reset rather than carrying the original cost from decades ago.

Couples relocating from community property states. If you moved to Tennessee from California, Texas, or another community property state, your assets may have lost their community property classification. A Tennessee Community Property Trust can restore it.

Couples with business interests. Closely held business shares that have appreciated substantially over the course of a career get a full basis adjustment, simplifying the surviving spouse's tax position if they sell or transfer the business.

Who Should Skip It

The Community Property Trust adds complexity that is not justified if:

• Your combined assets are modest (under $500,000 in appreciated value)
• Most of your wealth is in retirement accounts (which already receive their own basis treatment)
• You are in a high-conflict marriage (the divorce notice requirement exists for a reason — community property rules can complicate asset division)
• Neither spouse plans to sell appreciated assets after the first death

Community Property Trust vs. Standard Revocable Trust

The Tax Tracking Requirement

The double step-up is not automatic in practice. You need a CPA to calculate and document the adjusted basis of all trust assets at the first spouse's death. The IRS requires that community property be properly classified and reported for the basis reset to apply.

This is not optional paperwork — if you cannot demonstrate that the assets were held as community property in a qualifying trust at the time of death, the IRS can deny the double step-up and apply ordinary basis rules instead.

Setting Up a Community Property Trust

The trust itself is a revocable trust with specific statutory language electing community property treatment. The setup requires:

1. Drafting the trust agreement with the required Tennessee statutory provisions
2. Appointing a qualified Tennessee trustee (or serving as co-trustees with a qualified Tennessee trustee)
3. Funding the trust by transferring assets — deeds, account retitling, assignment of interests
4. Coordinating with a CPA to establish baseline cost basis records for all contributed assets

For couples whose estate planning needs go beyond what a basic will and beneficiary designations cover, the Community Property Trust is one of Tennessee's most powerful tools. If capital gains exposure is a primary concern, it is worth exploring alongside your broader Tennessee estate planning strategy.
