Yes, you can sell your house to your son for $1, and the deed will be valid. But the IRS does not care what price you wrote on the paperwork. It will treat the transaction as a gift equal to the home’s fair market value minus that $1, which means a $350,000 house becomes a $349,999 reportable gift. That classification sets off a chain of consequences — gift tax paperwork, a capital gains bill your son will inherit, and a five-year disqualification window for Medicaid — that most families don’t see coming until it’s too late to undo.
Why the IRS Calls It a Gift
Federal tax law is direct about transfers for less than fair market value. The difference between what you received and what the property is actually worth counts as a gift.1Office of the Law Revision Counsel. 26 USC 2512 – Valuation of Gifts The $1 price tag doesn’t change that, and it doesn’t reduce any of the reporting obligations. Every other consequence in this article flows from this one classification.
Gift Tax: Paperwork Yes, Money Probably No
Most families won’t owe actual gift tax on this kind of transfer. The reporting, however, is mandatory.
Annual Exclusion and Lifetime Exemption
For 2026, you can give any one person up to $19,000 per year without touching your lifetime exemption.2Internal Revenue Service. Gifts and Inheritances A house blows past that easily. The amount above $19,000 gets subtracted from your lifetime estate and gift tax exemption, which is $15,000,000 for 2026.3Internal Revenue Service. What’s New – Estate and Gift Tax If you’re married and your spouse joins the gift, each of you can apply your own $19,000 annual exclusion and your own $15 million exemption. Unless your combined estate exceeds $15 million, no gift tax actually comes due.
You Still Have to File Form 709
Even with no tax owed, you must file IRS Form 709 by April 15 of the year after the transfer.2Internal Revenue Service. Gifts and Inheritances This filing is how the IRS tracks how much of your lifetime exemption you’ve consumed, which it will need when calculating estate taxes after you die. For real estate, the return must include either a qualified appraisal or a detailed valuation, plus a legal description and the property’s condition.4Internal Revenue Service. Instructions for Form 709 Skipping the filing saves nothing and leaves your son with a documentation gap that becomes expensive to close later.
The Capital Gains Problem Your Son Inherits
This is where the $1 sale looks much worse than it first appears. When your son receives the house as a gift, he inherits your original tax basis — generally what you paid plus qualifying improvements.5Office of the Law Revision Counsel. 26 USC 1015 – Basis of Property Acquired by Gifts and Transfers in Trust That’s called a carryover basis, and it can produce a large capital gains bill whenever he eventually sells.
Here’s the math. Suppose you bought the house in 1995 for $120,000, and it’s now worth $350,000. If you gift it to your son and he later sells for $400,000, his taxable gain is calculated from your $120,000 basis. That’s a $280,000 gain. At the long-term capital gains rate of 15%, roughly $42,000 in federal tax. If he lives in the home as his primary residence for at least two of the five years before selling, he can exclude up to $250,000 of gain, or $500,000 if married filing jointly.6Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence For a rental, a second home, or gains above those limits, the carryover basis hits hard.
Inheritance Looks Very Different
If your son inherited the same house after your death instead of receiving it during your lifetime, he’d get a stepped-up basis equal to the home’s fair market value on the date you died.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 when you pass and he sells for $400,000, his gain is $50,000 instead of $280,000. That gap is the single strongest argument against transferring property during your lifetime. If avoiding probate is really what you’re after, a transfer-on-death deed or a revocable living trust can accomplish that while preserving the stepped-up basis.
The Medicaid Five-Year Look-Back
If there’s any chance you’ll need nursing home care or other long-term Medicaid benefits within the next five years, a $1 sale is one of the riskiest moves available. Federal law requires states to review every asset transfer made during 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 sold for a dollar is the textbook example of a transfer for less than fair market value.
The penalty is a period of Medicaid ineligibility, calculated by dividing the uncompensated value of the transferred asset by your state’s average monthly nursing home cost.8Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets A $300,000 house given away in a state with an average nursing home cost of $10,000 per month creates a 30-month penalty period during which Medicaid will not cover your care. Fractional months count. Anyone approaching retirement or already managing a serious health issue should talk with an elder law attorney before transferring property.
What Happens to the Mortgage
If there’s still a mortgage on the house, the transfer gets more complicated. Most mortgages contain a due-on-sale clause letting the lender demand full repayment whenever ownership changes. In theory, a $1 sale could trip that clause.
Federal law provides a safety net. The Garn-St. Germain Depository Institutions Act prohibits lenders from enforcing due-on-sale clauses when a borrower transfers a 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 transfer to your son is covered. The lender cannot call the loan due simply because the title changed.
The debt itself, though, doesn’t move. You remain personally liable on the loan unless your son refinances in his own name or the lender formally releases you. If he stops paying, the lender comes after you. His debt-to-income ratio also won’t reflect this mortgage when he applies for other credit, but yours still will.
Any existing liens on the property — tax liens, judgment liens, mechanic’s liens — travel with the house, not with you. Run a title search before the transfer. Skipping that step is how families discover years later that a contractor’s lien has been accruing interest in the background.
Property Tax Reassessment
In many jurisdictions, transferring property to a new owner triggers a reassessment of the home’s taxable value. If your property taxes have been based on an assessed value well below current market value — common where assessments lag appreciation — the transfer can push your son’s annual tax bill up sharply. Some states offer exemptions or reduced reassessment for parent-to-child transfers; most do not. Call your local assessor before signing. A jump from $3,000 to $7,000 a year changes the math on the whole arrangement.
Watch for Fraudulent Transfer Exposure
If you have outstanding debts, judgments, or pending lawsuits, a $1 sale to a family member can look like an attempt to put assets out of creditors’ reach. Most states have adopted some version of the Uniform Voidable Transactions Act, which lets creditors challenge transfers made without adequate consideration. A court can reverse the transfer entirely, leaving your son with nothing and you with a legal problem. Even without active creditors, a below-market transfer sitting in your financial history can complicate later borrowing and legal matters.
A Better Alternative: Gift of Equity
If the real goal is helping your son become the owner, a gift of equity usually works better than a $1 sale. You sell the house at or near fair market value and gift part of your equity to serve as his down payment. On a $350,000 home, you might gift $70,000 in equity — a 20% down payment — and your son takes out a mortgage for $280,000.
Fannie Mae allows gifts of equity to cover all or part of the down payment and closing costs on primary residences and second homes, and the donor isn’t treated as an “interested party” for underwriting purposes.10Fannie Mae. Gifts of Equity FHA loans also permit equity gifts, but only between family members, including parents and children.11U.S. Department of Housing and Urban Development. Does HUD Allow Gifts of Equity? Both require a signed gift letter identifying the donor, the relationship, the dollar amount, and the fact that no repayment is expected.
A gift of equity still requires Form 709 reporting for the gifted portion, and your son still gets a carryover basis on that portion. But he comes away with a real mortgage and a legitimate purchase history, the Medicaid look-back exposure shrinks dramatically, and the whole arrangement looks far cleaner to future lenders and buyers.
Before You Sign Anything
A few steps are worth doing in order:
- Get a qualified appraisal. The IRS requires it with Form 709, and it protects both of you if the valuation is ever questioned.
- Run a title search and clear any liens before the transfer.
- Notify your mortgage lender. Federal law protects the transfer, but telling the lender in advance avoids misunderstandings and opens the refinance conversation.
- Have an attorney prepare and record the deed. Fees generally run from $150 to $1,500 depending on complexity and location.
- File Form 709 by April 15 of the year after the transfer, including the appraisal, legal description, and property condition.
- Make sure your son has his own homeowner’s insurance policy effective on or before the transfer date; policies don’t travel with the property.
- Call the local assessor to find out whether the transfer triggers reassessment.
Selling your house to your son for $1 is legal, but it’s rarely the smartest way to move property to a child. Between the carryover basis, the Medicaid risk, and the mandatory reporting, most families come out ahead with a gift of equity, a trust, or simply letting the house pass through a will. An hour with a tax professional or estate planning attorney before any paperwork is signed is the best money you’ll spend in the entire process.
