Older homeowners often try to simplify their estate by adding an adult child to the deed of the family home. The logic seems sound: put the child on the title now, and the house should pass smoothly and avoid probate later. In practice, that single change can create a tax-filing obligation, hand a share of the home to the child’s creditors, and forfeit a valuable tax break that would otherwise apply at death. What looks like a shortcut is one of the more expensive moves a homeowner can make.
The gift-tax filing it can trigger
Putting a child’s name on a deed generally transfers a partial ownership interest in the property, and the tax code treats that transfer as a gift. When the value of the interest given away exceeds the annual exclusion, the parent is required to file a gift-tax return, Form 709, for the year. According to the IRS guidance on gift taxes, the annual exclusion is $19,000 per recipient for 2026, and a gift above that amount must be reported even when no tax is due. A half-interest in a home worth several hundred thousand dollars easily clears that threshold, so a deed change that felt informal becomes a reportable event. In most cases the parent owes no immediate tax, because the excess is applied against the lifetime gift and estate tax exemption, but the return still has to be filed and the exemption is reduced by the amount used.

The creditors the house is suddenly exposed to
Once a child is a legal co-owner, that child’s share of the home is an asset that the child’s problems can reach. A creditor who wins a judgment against the child, a lawsuit, a business failure, a car accident, or unpaid taxes can place a lien on the property or force a sale of the child’s interest. A divorce can drag the home into the division of marital assets. Even a bankruptcy filed by the child can put the house in play. The parent, who may still be living in the home and paying every bill, can find the property encumbered by a debt that has nothing to do with the household. Removing a co-owner once a claim has attached is difficult and sometimes impossible, so the exposure created by a well-meant deed change can outlast the reason it was made.
The step-up in basis that gets lost
The move also sacrifices a tax advantage that would otherwise pass to the child at death. When a home is inherited, its cost basis is generally stepped up to the market value on the date the owner dies, which can erase decades of appreciation for capital-gains purposes when the heir later sells. When a child is added to the deed during the parent’s life, the child usually takes over a share of the parent’s original, lower basis instead of receiving a stepped-up basis on that portion. The IRS treatment of lifetime gifts means the child can face a far larger taxable gain on a future sale than if the same interest had passed by inheritance. A gift intended to save money at transfer can quietly create a bigger tax bill down the road.
Homeowners who want a clean handoff of the family home have alternatives that avoid these traps. A transfer-on-death or beneficiary deed, available in many states, passes the property to a named heir at death without giving up control or exposing the home to a child’s creditors during life. A revocable living trust can accomplish the same goal while keeping the owner in charge and preserving the step-up in basis. Both keep the property out of probate without the gift-tax filing and liability that come with adding a co-owner. Before changing a deed, a homeowner is generally better served weighing those options with an estate attorney than reaching for the fastest fix, because the informal route is the one most likely to backfire.
A worked example of the tax the child inherits
Numbers make the lost step-up concrete. Suppose a parent bought a home decades ago for $60,000 and it is worth $560,000 when the parent adds an adult child to the deed as a half-owner. The child’s half carries over the parent’s basis on that share, roughly $30,000. If the child later sells that half for $280,000, the taxable gain on the child’s portion is about $250,000, and because the child never lived in the home as a main residence, the home-sale exclusion that shelters an owner’s own gain does not apply to it. Had the child instead inherited that same half at the parent’s death, the basis on the share would have stepped up to its date-of-death value, and a sale near that value could have produced little or no taxable gain. The gap between the two paths can be tens of thousands of dollars in capital-gains tax on a single sale.
The deed change can also collide with long-term-care planning. Giving away an interest in the home for no payment is a transfer for less than fair market value, the same kind of move Medicaid counts against an applicant during its five-year look-back at gifts. A parent who adds a child to the deed and then needs nursing care within that window can find the gift delaying Medicaid coverage on top of the gift-tax return and the creditor exposure the deed already created. Three separate problems can flow from one signature, which is why the informal fix so often costs a family far more than the probate it was meant to avoid.
