Guides › Medicaid and Your House
Updated July 31, 2026. Quick answer: adding a child to the deed is the most common do-it-yourself Medicaid move — and usually the worst one available. It is a gift of half the house the day it records: within the 60-month look-back, that is a penalty period computed on half the home’s value. The gifted half takes the parent’s carryover basis instead of the stepped-up basis an inheritance would get — a five-figure tax cost on a typical appreciated house. And the half now belongs to the child legally: exposed to their creditors, divorce, and bankruptcy, and the house cannot be sold or refinanced without their signature.
It often does not even do the Medicaid job
If the parent keeps a half interest, that half is still theirs — still in the estate, still reachable by estate recovery in every state (and in expanded-recovery states, even the joint-tenancy survivorship transfer may be reachable). So the family takes the penalty risk, the basis loss, and the creditor exposure — and the house is only half protected, at best.
What to do instead, by situation
A child who has genuinely lived in and cared for the parent for two years: the caregiver-child exemption moves the whole house penalty-free. A state with a TOD deed or Lady Bird deed: name the child as death-beneficiary — no gift today, full step-up at death, and in probate-only states no recovery either. Five-plus years of runway: completed gifts or an irrevocable trust clear the look-back entirely. Each beats the deed addition on every axis except how easy it is to do wrong.
The cheap fix that costs the most is still the most popular.
Ten minutes with a professional beats a recorded deed you cannot take back. The matching service below introduces you to advisers who pay to meet you.
Before you start, what actually happens. The form is run by Kapitalwise, our advisor-matching partner. It asks about nine questions — age, investable assets, location — then your name, email and phone number, and verifies the phone by text.
Kapitalwise sends your details to advisers who pay for the introduction, so expect calls and texts. Clear Money Guide is paid when you submit the form, whether or not you ever hire anyone. Nothing loads and nothing reaches Kapitalwise until you press the button.

The number that surprises people who bought a long time ago
Downsizing is the one home sale where the gain is usually large and the exclusion usually still covers it. A couple who bought in 1994 for $180,000 and sell at $760,000 with $46,000 of selling costs have a realized gain of about $534,000 before improvements. That is above the $500,000 joint cap — but decades of capital improvements are exactly what brings it back under, and most sellers have never added them up.
Improvements are the lever, and the records are the constraint
A new roof, an addition, a replaced HVAC system, new windows, a finished basement: these add to basis. Repainting and repairs do not. Thirty years of improvements on a family home routinely total six figures, and every dollar of it reduces the gain dollar for dollar. The practical problem is documentary, not legal — the seller who kept receipts pays less than the identical seller who did not.
Why downsizers should check the net investment income tax separately
A retiree with modest ordinary income can still be pushed over the 3.8 percent NIIT threshold by the sale itself, because taxable gain is net investment income. The thresholds are $250,000 on a joint return and $200,000 otherwise, written into Section 1411(b) as fixed figures with no indexing. A sale that produces $120,000 of taxable gain on top of $180,000 of other income crosses the joint threshold and picks up 3.8 percent on the part above it.
The move itself may change the tax
Downsizing usually means moving, and sometimes across a state line. Some states tax the gain the federal exclusion just removed. If the sale and the move are in the same year, the order of the two matters, and it is worth checking the destination state before signing.

Methodology
- Exclusion caps, the 2-of-5 test, the nonqualified-use allocation, the reduced-exclusion fraction and the depreciation carve-out are taken from the text of 26 U.S.C. 121. The 3.8 percent rate and its thresholds are from 26 U.S.C. 1411. Both were read on 2026-07-30.
- Section 121 caps and Section 1411 thresholds are written in the statute as fixed dollar amounts with no indexing mechanism, so they are built in. Long-term capital gain brackets ARE indexed annually, so your rate is an input rather than a lookup.
- Figures were computed by two independently written engines that agree to the cent, and the calculator on this page reproduces both exactly.
- Federal only. State treatment varies and some states do not follow the federal exclusion.
Educational estimate, not tax advice, and not a filed return. Federal only. Confirm anything that changes a filing decision with a CPA or tax attorney.
