You can legally sell your house to your son for $1, but the IRS will not treat it as a $1 sale. It treats it as a gift equal to the home’s fair market value minus that dollar. On a house appraised at $350,000, that’s a reportable gift of $349,999, and every tax consequence that follows flows from that reclassification: a required gift tax return, a cost basis your son inherits from you, a possible Medicaid penalty, and in some places a property tax reassessment. The transfer itself is simple. The consequences are not.
Why the IRS Ignores the $1 Price Tag
Federal law is direct on this: when you transfer property for less than its fair market value, the gap between what you received and what the property is worth counts as a gift.1Office of the Law Revision Counsel. 26 USC 2512 – Valuation of Gifts Writing “$1” on the deed changes nothing about how the transaction is taxed. The IRS looks at fair market value, and so do state Medicaid agencies, mortgage lenders, and county assessors. Treat the sale price as a legal formality, not a tax strategy.
Gift Tax: You Probably Won’t Owe, But You Must File
Most parents transferring a home this way pay no federal gift tax. The paperwork, though, is not optional.
How the Exclusion and Exemption Work
For 2026, you can give any one person up to $19,000 a year without touching your lifetime exemption.2Internal Revenue Service. Gifts and Inheritances A house obliterates that threshold. The amount over $19,000 gets subtracted from your lifetime estate and gift tax exemption, which for 2026 sits at $15,000,000.3Internal Revenue Service. What’s New – Estate and Gift Tax If you’re married and your spouse consents to split the gift, each of you applies a separate $19,000 exclusion and a separate $15 million exemption. Unless your total lifetime giving plus your estate approaches those numbers, no gift tax will come due.
Form 709 Is Required Anyway
Even when nothing is owed, you must file IRS Form 709 by April 15 of the year after the transfer.2Internal Revenue Service. Gifts and Inheritances The return records how much of your lifetime exemption you’ve spent, which the IRS uses later to compute estate tax. For a real estate gift, the return needs either a qualified appraisal or a detailed description of how you arrived at fair market value, along with a legal description and the property’s condition.4Internal Revenue Service. Instructions for Form 709 Skipping the filing saves nothing and leaves a documentation gap that gets expensive to close later.
The Carryover Basis Problem
This is where a $1 sale quietly costs families the most money. When your son receives the house as a gift, he takes your cost basis with it: what you originally paid, plus qualifying improvements.5Office of the Law Revision Counsel. 26 USC 1015 – Basis of Property Acquired by Gifts and Transfers in Trust That carryover basis follows him until he sells.
Suppose you bought the house in 1995 for $120,000, and today it’s worth $350,000. You transfer it to your son for $1. Years later he sells for $400,000. His taxable gain is measured from your $120,000 basis, not the $350,000 value at transfer. That’s a $280,000 gain. At the 15% long-term capital gains rate, roughly $42,000 goes to federal tax alone. He can exclude up to $250,000 of gain ($500,000 if married filing jointly) if he lived in the home as his primary residence for at least two of the five years before selling.6Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence Rental property, second homes, and larger gains don’t get that shelter.
Inheritance Produces a Very Different Result
If your son inherits the house after your death instead, he receives a stepped-up basis equal to the fair market value on the date you die.7Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent Using the same numbers, if the house is worth $350,000 at your death and he sells for $400,000, his taxable gain is $50,000 rather than $280,000. That single difference is the strongest argument against transferring appreciated property during your lifetime. If avoiding probate is the real goal, a transfer-on-death deed or a revocable living trust can accomplish that and still preserve the stepped-up basis.
Medicaid Look-Back: The Sharpest Risk
If there’s any chance you’ll need nursing home care or other long-term Medicaid benefits in the next few years, selling your home for $1 is one of the worst moves you can make. Federal law requires states to review every asset transfer made in the 60 months before a Medicaid application.8Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets A house transferred for $1 is the textbook uncompensated transfer.
The penalty is a period of Medicaid ineligibility. States calculate it by dividing the uncompensated value by the average monthly cost of nursing home care in that state.8Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets Give away a $300,000 house in a state where average nursing home cost is $10,000 a month, and you’re looking at a 30-month stretch during which Medicaid won’t cover your care. Fractional months count; states can’t round down. Anyone approaching retirement age should speak with an elder law attorney before signing anything.
What Happens to Your Mortgage
An existing mortgage complicates the picture. Most mortgages contain a due-on-sale clause letting the lender demand full repayment when ownership changes. On its face, a $1 sale would trigger it.
Federal law blocks that outcome for family transfers. The Garn-St. Germain Depository Institutions Act prohibits lenders from enforcing due-on-sale clauses when a borrower transfers residential property of fewer than five units to their children.9Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions A parent-to-son transfer is squarely covered.
The mortgage itself does not disappear. You remain personally liable on the loan until your son refinances in his own name or the lender formally releases you. If he stops paying, the lender comes after you. The debt also stays on your credit report and affects your borrowing capacity, not his. Any liens attached to the property (tax liens, judgment liens, mechanic’s liens) travel with the house, so a title search before the transfer is not optional.
If You Owe Money, a $1 Sale Can Be Reversed
If you have outstanding debts, judgments, or pending lawsuits, transferring a house for $1 can be attacked as a fraudulent transfer. Most states have some version of the Uniform Voidable Transactions Act, which allows creditors to unwind transfers made without adequate consideration. A court can reverse the deed entirely, leaving your son with nothing and you facing the original creditor plus legal costs. This risk applies even if defrauding creditors was the last thing on your mind; the below-market price is what triggers the analysis.
Property Tax Reassessment
Many jurisdictions reassess a property for tax purposes when ownership changes. If your assessed value has lagged well behind market value (common in long-held homes), your son could inherit a much larger annual tax bill than you’ve been paying. A few states offer exemptions or reduced reassessment for parent-to-child transfers, but most do not. Call the local assessor before you sign. A jump from $3,000 to $7,000 in annual property tax changes the arithmetic on the whole idea.
A Better Path for Most Families: Gift of Equity
If the goal is to help your son buy the home rather than hand it to him outright, a gift of equity usually beats a $1 sale. You sell at or near fair market value, and gift a portion of your equity to serve as his down payment. On a $350,000 home, gifting $70,000 in equity covers a 20% down payment and your son takes a mortgage for $280,000.
Fannie Mae allows gifts of equity to cover down payment and closing costs on primary residence and second-home purchases, and the donor is not treated as an interested party for underwriting.10Fannie Mae. Gifts of Equity FHA loans permit equity gifts between family members, which includes parents and children.11U.S. Department of Housing and Urban Development. Does HUD Allow Gifts of Equity? Both require a signed gift letter naming the donor, the relationship, the amount, and confirming no repayment is expected.
You still file Form 709 for the gifted portion, and your son still takes a carryover basis on that piece. But he ends up with a real mortgage and a legitimate purchase price, the Medicaid look-back exposure shrinks dramatically, and the transaction reads cleanly to future lenders and buyers.
If You Still Want to Go Through With It
Assume you’ve weighed the alternatives and decided the $1 sale is the right move. A few practical points shape whether the transfer goes smoothly.
The deed type matters. A quitclaim deed transfers whatever interest you hold and makes no promises about the quality of title; if an old lien surfaces, your son has no recourse against you. Quitclaims are cheap and common in family transfers. A warranty deed guarantees clear title and obligates you to defend against later claims, which offers your son more protection but creates a legal duty between you. Either deed must be recorded with the county recorder to establish public notice and claim priority. Recording fees are usually modest.
A working checklist for the transfer itself:
- Order a qualified appraisal to establish fair market value; Form 709 needs it, and it protects both of you if the transfer is questioned.
- Run a title search and clear any liens or judgments before closing.
- Notify your mortgage lender. Garn-St. Germain protects the transfer, but the conversation about refinancing should happen up front.
- Have an attorney draft the deed. Fees typically run from $150 to $1,500 depending on complexity and location.
- File Form 709 by April 15 of the year after the transfer, with the appraisal, legal description, and property condition.
- Get your son his own homeowner’s insurance policy effective on or before the transfer date. Policies do not follow the property.
- Check with the local assessor on whether the transfer triggers reassessment.
The $1 sale is legal and mechanically simple. It is also rarely the cheapest way to move a house to a child. Between the carryover basis, the Medicaid look-back, and the reporting obligations, most families end up better served by a gift of equity, a trust, or an inheritance through a will. An hour with a tax professional or estate planning attorney before anything gets signed is worth more than any tactic in this article.
