Exclusion of capital gains on primary residence sales
Up to $250,000 of gain on selling a home ($500,000 married) is untaxed.
JCT line: "Exclusion of capital gains on sales of principal residences".
Broad among homeowners, but the benefit is proportional to accrued appreciation, which concentrates in high-cost markets and among long-tenured owners. Renters receive nothing.
Structural reading
A useful mid-scale case because the concentration runs on an axis other than income. Two households with identical earnings receive wildly different benefits depending on when they bought and in which market, the transfer tracks asset position and timing rather than need. The unindexed thresholds cut the other way: because they have not moved since 1997, ordinary price inflation is slowly converting an upper-middle-class benefit into one that binds on ordinary sales, which is why indexation draws support from both parties.
Who gets it
The channels the benefit actually flows through, described by asset position, entity form and form of return. Never by named individuals.
Cost split by the concentration score. That score is a judgement rather than a published figure, so treat this as the scale of the split, not an audited allocation.
- Long-tenured owners in high-appreciation markets
The exclusion's value tracks accrued gain, so identical households receive very different benefits depending on when and where they bought.
- Repeat claimants
The exclusion may be claimed every two years without limit, unlike the one-time rollover it replaced.
- Structural exclusion of renters
The benefit attaches to a form of asset ownership rather than to housing need, so it is unavailable to the roughly third of households that rent.
Who pays
Taxpayers generally, including renters, who fund the exclusion without access to it.

This transfer follows a general pattern, asymmetric organisation, sustained expert attention, and scheduled expiry dates.

Reform proposal
- Proposals to index the exclusion thresholds to inflationlive
The $250,000/$500,000 thresholds have been unchanged since 1997, so ordinary house price inflation has gradually pulled more sales above them. Indexation proposals have been introduced with support from both parties.
Lobbying around this provision
This is not campaign money, and it is not attributable to the votes above. Lobbying disclosures record what organisations spent engaging policymakers across an entire issue area over a quarter. They are not broken out by party, by member, or by bill, and no part of this figure can be traced to any vote on this page. It is shown as an indicator of how organised the interest around this provision is, nothing more.
Demonstrating an actual relationship between money and votes would require campaign contribution records matched to each member of the roll call. That is a different dataset and is not yet built here.
