Capital Gains Tax Guide for Home Sellers in US: Rules,

Section 121 and Other Exclusions

The main exclusion for capital gains tax on a home sale is Section 121 of the Internal Revenue Code, which allows home sellers to exclude up to $250,000 of gain for single filers and $500,000 for joint filers. However, there are specific tests and ownership and occupancy requirements that must be met to qualify.

	Single Filer	Married Filing Jointly
Exclusion Amount	$250,000	$500,000
Ownership Test	Owned the home 2 of the last 5 years	At least one spouse must meet this
Occupancy Test	Lived in the home 2 of the last 5 years	Both spouses must meet this
Frequency	Once every 2 years	Once every 2 years

Example Scenarios

Understanding how the rules apply in different scenarios is crucial. Here we provide examples for single sellers, married joint filers, over-limit gain situations, early sales, and home office use.

Illustrative examples, not real customer stories:

• Single seller: A single filer with $200,000 in gain on their primary residence, meeting the 2-of-5-year test, owes no capital gains tax -- the gain is fully within the $250,000 exclusion.
• Married joint filers: A married couple filing jointly with $400,000 in gain, meeting the test, also owes nothing -- it's within their $500,000 exclusion.
• Over-limit gain: A single filer with $300,000 in gain owes capital gains tax on the $50,000 above their $250,000 exclusion.
• Early sale: A seller who lived in the home for only 18 months (short of the 2-of-5-year test) may still qualify for a partial exclusion if the sale was due to a qualifying reason like a job change, health issue, or unforeseeable circumstance.
• Home office use: A seller who claimed a home office deduction may owe tax on the portion of gain attributable to that business-use space, even if the rest of the gain is excluded.

State-Level Variation

This guide covers federal capital gains tax rules. Separately, most states also tax capital gains -- some (like Texas and Florida) have no state income tax and therefore no state-level capital gains tax on a home sale, while others tax it as ordinary income. Check your specific state's rules in addition to the federal Section 121 exclusion covered here.
