What this guide covers
A quick view of the questions and evidence developed below.
Updated August 21, 2026. Quick answer: selling before you have owned and lived in the home for two years usually means no full exclusion — but often a partial one, and the partial exclusion is far more generous than people expect. If your move is for a qualifying reason — a job relocation, health, or an unforeseen circumstance — you get a fraction of the $250,000 or $500,000, prorated by how much of the twenty-four months you actually completed. Sell at eighteen months for a qualifying reason and roughly three-quarters of the exclusion is still yours.
The proration, in plain arithmetic
The fraction is the shorter of your ownership or use period, measured in months, over twenty-four. At 18 of 24 months that is 75%: a married couple’s $500,000 becomes $375,000, and a single seller’s $250,000 becomes $187,500. That is usually more than enough to cover a gain accumulated over eighteen months.
This is the part that surprises people: the partial exclusion is not a small consolation. For most short-hold sales it eliminates the tax entirely, because a gain built in under two years rarely approaches even the prorated cap.
What counts as a qualifying reason
- Work. A change in employment location, with a distance test that mirrors the old moving- expense rule. This is the most commonly used category.
- Health. A move to obtain or provide care — including for a parent or child, not only yourself. A doctor’s recommendation is the usual evidence.
- Unforeseen circumstances. A defined list including death, divorce or legal separation, multiple births from one pregnancy, job loss qualifying for unemployment, and a change in employment leaving you unable to pay basic living expenses — plus a facts-and-circumstances route for events genuinely outside your control.
What does not qualify: selling because you found a house you liked better, because the market moved, or because you changed your mind. A voluntary lifestyle move is exactly the case the rule excludes. The relocation route in detail.
A sale inside two years is usually part of a bigger move.
Sell at eighteen of the twenty four months for a qualifying reason and a married couple’s $500,000 exclusion is still $375,000, a single seller’s $250,000 still $187,500. Relocation, a job change or a health event all reshape the tax year around them, not just the house. 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. 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. This is free to you and there is no obligation to hire anyone.
The Kapitalwise form opens here — you stay on this page.
What happens when you press the button
It asks about nine questions — age, investable assets, location — then your name, email and phone number, and verifies the phone by text. Nothing loads and nothing reaches Kapitalwise until you press the button.
If no reason qualifies
Then the whole gain is taxable, and how it is taxed depends on one date: whether you owned it for more than a year. Under a year and the gain is short-term, taxed at ordinary income rates. Over a year and it is long-term, at the lower capital-gains rates. If you are close to the twelve-month line and the sale is discretionary, waiting can be worth a great deal more than the price movement in between.
And if you are close to twenty-four months, the arithmetic is even starker — the difference between month 23 and month 24 can be the difference between a prorated exclusion and the full one. Run both dates: the Section 121 calculator applies the test in months.
Two things people forget in a fast sale
Selling costs come off the gain. Agent commission, legal fees and transfer taxes reduce the amount realised, which on a short hold is often enough to erase a modest gain by itself. Improvements count too — anything capital you did in those eighteen months adds to basis, and on a quick renovate-and-sell that is frequently the largest single adjustment.

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. There is no calculator on this page; the Section 121 calculator linked above is a separate page.
- Federal only. State treatment varies and some states do not follow the federal exclusion — what each state does with a long-term gain.
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.
