Trump Officials Float Cut To Capital Gains Tax On Home Sales
Illustration generated for Bill & Budget.
This debate has resurfaced following comments from National Economic Council Director Kevin Hassett and Larry Kudlow regarding potential tax breaks for home sales. With legislative proposals like the More Homes on the Market Act floating in Congress, some homeowners are now questioning whether to hold their properties in hopes of a more favourable tax regime.
For the "empty nester" who bought a home decades ago, the idea of indexing capital gains to inflation sounds like a necessary correction. It suggests that the government is stealing the purchasing power of your hard-earned equity. But this is a psychological trap.
By labelling the current structure a "Biden inflation tax," proponents use a loss-aversion frame. This triggers a visceral reaction: the feeling that something is being taken away from you. Imagine a married couple who bought a home for $100,000 and now see it valued at $500,000. They have a $400,000 gain. Under current law, their Section 121 exclusion shields $500,000 of profit. They owe zero in capital gains tax. Yet, when they hear that inflation is "eating" their gains, they feel a sense of loss. They begin to crave a tax break for a tax they aren't even paying. This is framing in action; it moves the homeowner to support a policy based on a perceived loss rather than their actual financial reality.
The reality is that the current thresholds are remarkably generous. Under existing IRS rules, single filers can exclude $250,000 of profit, and married couples filing jointly can exclude $500,000. According to data from The Budget Lab at Yale cited by CNBC, only about 10% of homeowners in 2022 had gains exceeding these exemptions. Those individuals had an average net worth of roughly $5.7 million.
For the other 90%, the proposed changes are a solution in search of a problem. Whether the government indexes the basis to inflation or doubles the exemption, the net result for the average seller is exactly the same: a tax bill of zero.
The danger here is not the tax itself, but the decision-making process of the homeowner. If you delay the sale of a primary residence to wait for a legislative change that provides you no actual benefit, you are committing a strategic error. You are holding an asset—perhaps a house too large for your current needs—based on a political promise that serves a different demographic. Waiting for a "tax break" that doesn't change your bottom line is like waiting for a second free sample at a supermarket when you already have the full product in your basket.
To avoid this trap, you must stop looking at the political rhetoric and start looking at your own ledger. The capital gains tax on a home is not a mystery; it is a simple calculation of adjusted basis versus sale price.
If you are considering a move, use this framework to determine if these proposed changes actually matter to your wallet:
1. Calculate your home's adjusted basis. Do not just look at the original purchase price. Add the cost of all capital improvements—such as a new roof, a kitchen remodel, or an addition—made over the years. This increases your basis and lowers your taxable gain. 2. Estimate your current home equity. Subtract your adjusted basis from your projected sale price. If that profit is under $250,000 for a single person or $500,000 for a married couple, you are already shielded by the Section 121 exclusion. 3. Compare your projected taxable gain against the long-term capital gains brackets. If you do exceed the threshold, your tax rate will be 0%, 15%, or 20% depending on your taxable income. Determine if the potential savings from a new law outweigh the costs of maintaining the property for another two to four years.
We must also be clear about the legislative hurdles. Financial planners told CNBC that passing such changes through Congress is a slow and difficult process. A proposal is not a law, and a "interest" from the White House is not a guarantee of a check in your pocket.
For the vast majority of Americans, the current tax code already provides the "break" they are being told they need. The goal of a savvy homeowner should be to optimise their portfolio based on current law and personal lifestyle needs, not to gamble their timing on a policy that primarily benefits the ultra-wealthy.
When you strip away the labels and the political framing, the math remains the same. If you are under the threshold, you are already winning. Do not let a political narrative convince you to hold onto an inefficient asset for a benefit you will never receive.
