What Is Step-Up in Basis?
A tax provision that adjusts the cost basis of inherited assets to their fair market value at the date of the decedent's death, eliminating capital gains tax on appreciation during the decedent's lifetime.
Understanding Step-Up in Basis
Step-up in basis is a federal tax provision under IRC Section 1014 that adjusts the cost basis of inherited assets to their fair market value at the date of the decedent's death (or an alternate valuation date six months later). This means that any capital gains accumulated during the decedent's lifetime are effectively eliminated for income tax purposes. When the heir eventually sells the inherited asset, they only pay capital gains tax on the appreciation that occurred after the date of inheritance, not on the total appreciation over the original owner's holding period.
Step-up in basis applies to most types of property, including real estate, stocks, bonds, business interests, and other capital assets. However, it does not apply to assets held in certain types of accounts, such as traditional IRAs, 401(k)s, and other tax-deferred retirement accounts, because distributions from these accounts are taxed as ordinary income regardless. Life insurance death benefits are not subject to step-up in basis because they are already received income-tax-free under IRC Section 101(a).
The interplay between step-up in basis and life insurance planning is significant. For estate planning purposes, some assets are better transferred at death (to receive the step-up) while others may be better transferred during lifetime through gifts or trusts. Life insurance can provide the liquidity for heirs to hold inherited assets rather than selling them at unfavorable times, maximizing the benefit of the step-up. Understanding which assets receive a step-up and which do not is essential for comprehensive estate planning.
For jointly held property, the step-up rules vary depending on whether the property is held as community property or separate property. In separate property states like Tennessee, only the deceased spouse's share of jointly held property receives a step-up at death. In community property states, the surviving spouse may receive a full step-up on both halves of community property. Tennessee residents who own property in community property states or who have moved between separate and community property jurisdictions should work with estate attorneys experienced in multi-state issues to maximize step-up benefits. Step-up in basis has been the subject of recent legislative proposals to limit or eliminate the provision for high-value estates, making forward-looking estate planning that includes life insurance flexibility increasingly important.

Seeing Step-Up in Basis in Practice
Illustrative example: A 72-year-old Knoxville resident purchased farmland in 1985 for $200,000. At the time of her death, the land is valued at $1,500,000. Her son inherits the land with a stepped-up basis of $1,500,000. If he sells the land for $1,600,000, he pays capital gains tax only on $100,000 (the appreciation after inheritance), not on the full $1,300,000 gain from the original purchase price. Meanwhile, a $500,000 life insurance policy provides additional liquidity so the son has the option to keep the land rather than selling to cover expenses. This example is illustrative only; actual tax calculations depend on current law and individual circumstances. In a second illustrative scenario, a 68-year-old Memphis investor inherits a stock portfolio worth $2 million from her late husband, who originally purchased the stocks for $400,000. Because the stocks receive a stepped-up basis to $2 million at his death, she avoids approximately $320,000 in federal capital gains tax (assuming a 20% capital gains rate on the $1.6 million gain) when she eventually rebalances the portfolio. The same stocks held in his traditional IRA, however, would not receive a step-up; distributions from the inherited IRA would be taxed as ordinary income at her marginal rate. Actual outcomes depend on current law and individual circumstances.
Step-Up in Basis in Tennessee
Tennessee residents benefit significantly from the step-up in basis provision because Tennessee has no state capital gains tax (no state income tax). This means inherited assets receive a federal step-up in basis and face no additional state tax. For Tennessee families with significant real estate, farmland, business interests, or investment portfolios, this provision can save tens or hundreds of thousands of dollars in taxes. In practice, agents in our network help Tennessee families integrate life insurance planning with the step-up in basis strategy. Life insurance provides the liquidity for heirs to retain stepped-up assets, which is particularly important in Tennessee's agricultural and real estate markets where forced sales of farmland or commercial property can destroy generational wealth. For Tennessee business owners, life insurance funded buy-sell agreements ensure that business interests can transition smoothly while heirs retain the benefit of the stepped-up basis. Coordination among agents, estate planning attorneys, and CPAs helps Tennessee families maximize the combined benefits of step-up in basis, the absence of state income and estate taxes, and life insurance liquidity strategies. Guarantees on life insurance policies are backed by the financial strength and claims-paying ability of the issuing insurance carrier.

Life insurance death benefits do not need step-up treatment because they are already received entirely income-tax-free under IRC Section 101(a). The step-up in basis provision is relevant to other inherited assets such as real estate, stocks, and business interests. Life insurance complements the step-up by providing liquidity for heirs to retain these stepped-up assets.
No. Tennessee has no state income tax, including no state capital gains tax. Inherited assets that receive a federal step-up in basis face no additional state tax in Tennessee. This makes Tennessee one of the most favorable states for receiving inherited assets.
Step-up in basis has been the subject of legislative proposals in recent years. Some proposals have suggested eliminating or limiting the step-up for estates above certain thresholds. Because the law may change, estate planning professionals recommend strategies that provide flexibility, such as life insurance in an ILIT, which provides benefits regardless of step-up rules.
In separate property states like Tennessee, only the deceased spouse's share of jointly held property receives a step-up at death. In community property states, the surviving spouse generally receives a full step-up on both halves of community property. Tennessee residents who own property in community property states should consult with an estate attorney to understand how the rules apply.
Estate executors may elect to value estate assets six months after the date of death (instead of the date of death itself) if doing so produces a lower estate tax liability. The election applies to all estate assets uniformly. This option is most useful when asset values have declined after death. The alternate valuation date affects both estate tax calculations and the stepped-up basis received by heirs.
