“Why not just add your child to the deed?”
It sounds like a simple solution. By making an adult child a joint owner of the family home, a parent may hope to avoid probate and make the eventual transfer easier.
But adding someone to a deed is more than just an administrative change. It can be a gift of real ownership—and it may also transfer a portion of the home’s existing tax basis. In some cases, the shortcut intended to save time and money can instead create a substantial capital-gains tax bill.
Consider a parent who purchased a home many years ago for $200,000. Today, the home is worth $800,000. To simplify the transfer at death, the parent adds an adult daughter to the deed as a 50% joint owner.
Although the parent still lives in the home and may continue paying all its expenses, the daughter has received an ownership interest worth approximately $400,000. The IRS generally considers a transfer of property for less than full value to be a gift. Because the value exceeds the 2026 annual gift-tax exclusion of $19,000, the parent may also need to file a federal gift-tax return—even if no gift tax is immediately payable.
The bigger potential cost may surface later.
Property received as a gift generally retains the donor’s existing basis. Property inherited at death, by contrast, generally receives a new basis related to its fair market value at the owner’s death.
In this simplified example, the daughter’s gifted half of the home carries approximately $100,000 of the parent’s original basis. When the parent dies, the parent’s retained half may receive a basis adjustment to its then-current value of $400,000.
The daughter’s total basis could therefore be approximately:
- $100,000 for the half received as a gift
- $400,000 for the half inherited at death
- $500,000 total basis
If she then sells the home for $800,000, she could have a taxable gain of approximately $300,000.
At an illustrative combined federal and state capital-gains tax rate of 25%, that could produce a tax bill of approximately $75,000. With a more highly appreciated home, a complete lifetime transfer, or higher applicable taxes, the cost could readily reach six figures.
The home-sale exclusion may not solve the problem. Although qualifying homeowners may exclude up to $250,000 of gain—or $500,000 for certain married couples—the taxpayer generally must satisfy ownership and residence requirements. A child who hasn’t lived in the home may not qualify simply because the parent did.
Taxes are not the only concern. Once the child becomes an owner, the home may be affected by the child’s creditors, divorce, death, or financial decisions. The parent may also lose the ability to sell or refinance the property without the child’s cooperation.
Depending on state law and the family’s circumstances, a trust, beneficiary deed, or another properly structured arrangement may simplify the eventual transfer without giving away part of the home today.
Avoiding probate can be a worthwhile goal. But before adding a child to a deed, families should consider what else they may be transferring, including control, legal exposure, and a potentially significant tax liability.
