What Is a Step-Up in Basis—and Why Does It Matter in Estate Planning?
When families discuss estate planning, they often focus on who will inherit a home, investment account, or business interest. An equally important question is what the beneficiary’s tax basis in that asset will be.
The answer can have a significant effect on the capital gains tax due when the beneficiary later sells the property.
Under federal tax law, many assets acquired from a deceased owner receive a new basis equal to their fair market value as of the owner’s date of death. This adjustment is commonly called a “step-up in basis.” If the asset has increased substantially in value during the owner’s lifetime, the adjustment may eliminate much of the taxable gain that accumulated before death.
However, not every asset receives a basis adjustment, and transferring an asset during life may produce a very different tax result than allowing it to pass at death.
What Is Tax Basis?
Tax basis is generally the amount used to calculate gain or loss when an asset is sold.
For property that is purchased, the initial basis is usually the purchase price, plus certain acquisition costs and capital improvements. The basis may later be reduced by items such as depreciation.
When the property is sold, the taxable gain is generally calculated by subtracting the owner’s adjusted basis and eligible selling expenses from the sale price.
For example, assume a parent purchased a Florida home for $200,000 and later made $50,000 in qualifying improvements. The parent’s adjusted basis may be approximately $250,000. If the home is later sold for $800,000, the difference between the sale price and adjusted basis could create a substantial capital gain, subject to any available exclusions or other adjustments.
How Does a Step-Up in Basis Work?
Property inherited from a deceased owner generally receives a basis equal to its fair market value on the owner’s date of death. In some taxable estates, the personal representative may elect an alternate valuation date, but the date-of-death value is the usual rule.
Using the same example, assume the parent still owned the home at death and the property was worth $800,000 at that time. If the child inherits the home, the child’s new basis may be $800,000—not the parent’s $250,000 adjusted basis.
If the child sells the property shortly afterward for $810,000, the taxable gain may be approximately $10,000, subject to selling expenses and other adjustments. The appreciation that occurred during the parent’s lifetime is generally not included in the child’s gain.
Although the rule is commonly called a step-up, basis can also be adjusted downward. If an asset is worth less on the date of death than the deceased owner’s adjusted basis, the beneficiary’s basis may be reduced to that lower fair market value.
Does the Property Have to Go Through Probate?
Not necessarily.
Probate and tax basis are separate issues. An asset does not generally have to pass through a probate administration to qualify for a date-of-death basis adjustment.
Depending on the circumstances, property may receive an adjusted basis even if it passes through:
A revocable living trust
Joint ownership with a right of survivorship
A beneficiary designation
A life-estate or enhanced life-estate deed
A will or intestate succession through probate
The method used to avoid probate does not, by itself, determine the income-tax treatment. The ownership arrangement, the rights retained by the deceased owner, and whether the property is treated as acquired from the decedent under federal tax law all matter.
Does Property in a Revocable Trust Receive a Step-Up in Basis?
Generally, assets properly titled in a revocable living trust remain part of the settlor’s estate for federal estate-tax purposes and may receive a basis adjustment at the settlor’s death.
This means a person does not usually have to choose between probate avoidance and preserving a potential step-up in basis. A properly funded revocable trust can allow assets to be administered outside probate while still receiving the applicable date-of-death basis adjustment.
The analysis may be different for an irrevocable trust. If the person creating the trust gives up sufficient ownership and control so that the asset is not included in that person’s gross estate, the asset may not receive a basis adjustment at that person’s death. The trust terms, retained powers, funding history, and applicable tax rules must be reviewed before reaching a conclusion.
Is Inheriting Property Different From Receiving It as a Gift?
Yes. This is one of the most important distinctions in basis planning.
When appreciated property is given away during the owner’s lifetime, the recipient generally receives the donor’s existing adjusted basis. This is known as carryover basis.
Assume a parent gives a child the home described above while the parent is living. The home is worth $800,000, but the parent’s adjusted basis is $250,000. The child will generally take the parent’s $250,000 basis. If the child later sells the home for $810,000, the child may have approximately $560,000 of gain before considering selling expenses, exclusions, or other adjustments.
If the child instead inherits the home at the parent’s death when it is worth $800,000, the child may receive an $800,000 basis. The difference can be substantial.
For that reason, adding a child to a deed during life is not merely a probate-avoidance decision. It may create gift-tax reporting issues, expose the property to the child’s creditors or divorce, reduce the parent’s control, and cause the child to receive carryover basis on the gifted portion.
What Happens When Spouses Own Florida Property Together?
When Florida spouses own property jointly—often as tenants by the entirety—the death of one spouse does not necessarily produce a new basis for the entire property.
As a general rule, the deceased spouse’s share receives a date-of-death basis adjustment, while the surviving spouse’s existing share keeps its prior adjusted basis. The surviving spouse’s new total basis is therefore a combination of the adjusted basis in the surviving spouse’s portion and the date-of-death value of the deceased spouse’s portion.
For example, assume spouses purchased a home for $400,000 and it is worth $1 million when one spouse dies. In a simplified fifty-percent example, the deceased spouse’s half may receive a new basis of $500,000, while the surviving spouse’s half may retain a $200,000 basis. The surviving spouse’s combined basis would then be approximately $700,000, subject to improvements, depreciation, ownership history, and other adjustments.
Florida is not a community-property state. Accordingly, married Florida property owners should not assume that both halves of a jointly owned asset will automatically receive a full basis adjustment at the first spouse’s death.
What Types of Assets May Receive a Basis Adjustment?
The rule may apply to many capital assets acquired from a deceased owner, including:
Real estate
Stocks, bonds, and non-retirement investment accounts
Interests in closely held businesses
LLC membership interests and partnership interests
Collectibles and other valuable personal property
Certain assets require different treatment. Cash does not appreciate and therefore does not benefit from a basis adjustment. Traditional retirement accounts, accrued income, installment-sale payments, and other items classified as income in respect of a decedent may remain subject to income tax when received.
Life-insurance proceeds are also governed by separate rules and are not analyzed in the same manner as the sale of an appreciated capital asset.
What Happens to an Inherited LLC Interest?
An inherited LLC membership interest may receive a basis adjustment at the owner’s death. However, the adjustment to the beneficiary’s basis in the membership interest does not necessarily adjust the LLC’s basis in the assets it owns.
This is sometimes described as the difference between “outside basis”—the owner’s basis in the LLC or partnership interest—and “inside basis”—the entity’s basis in its property.
Depending on how the LLC is taxed, additional elections or tax planning may be needed to align those amounts. The operating agreement, entity tax classification, ownership structure, and intended sale should be reviewed with legal and tax advisors.
This issue is especially important when an LLC owns highly appreciated real estate or a closely held business.
How Is the Date-of-Death Value Established?
Beneficiaries should not rely on an informal estimate or the county property appraiser’s assessed value.
For real estate, a retrospective appraisal as of the date of death is often the best evidence of fair market value. Publicly traded securities can generally be valued using the applicable market prices. Closely held businesses, LLC interests, artwork, and other non-public assets may require a qualified valuation professional.
The personal representative, trustee, surviving owner, and beneficiaries should preserve:
The date-of-death appraisal or valuation
Closing statements and acquisition records
Receipts for capital improvements
Depreciation schedules
Estate-tax returns and related valuation schedules, if any
Documents showing how title was held
This documentation may be needed years later when the beneficiary sells the asset. A formal federal estate-tax return is not required merely to obtain a basis adjustment, although special reporting and consistency rules may apply when an estate is required to file one.
Why Basis Planning Should Be Part of Estate Planning
The plan that appears simplest during life may not produce the best overall result for the family.
An outright lifetime transfer may avoid probate, but it can also transfer a low basis to the recipient. A revocable trust or properly structured deed may avoid probate while preserving a potential date-of-death basis adjustment. An irrevocable trust may accomplish important asset-protection, gift, or estate-tax objectives, but the income-tax consequences must be considered as part of the design.
There is no single strategy that is right for every asset or every family. The potential capital-gains savings must be weighed against estate-tax exposure, creditor protection, Medicaid planning, control, probate avoidance, and the owner’s personal goals.
The Bottom Line
A step-up in basis can significantly reduce the capital-gains tax associated with inherited property, but it is not automatic for every transfer or every asset.
Before gifting appreciated property, adding a family member to a deed, funding an irrevocable trust, or changing the ownership of a business interest, consider how the transfer may affect both probate and tax basis. Estate-planning documents, ownership records, and tax planning should work together so that an effort to solve one problem does not unintentionally create another.
