What Is the Section 121 Principal Residence Gain Exclusion?
When a taxpayer sells a principal residence, the Internal Revenue Code allows eligible homeowners to exclude a portion of the gain from taxable income under Section 121. Individuals may exclude up to $250,000 of gain, while married couples filing jointly may exclude up to $500,000 if they meet certain ownership and residency requirements.
If the IRS questions whether the taxpayer qualifies for this exclusion, the result can be a significant proposed tax assessment along with potential penalties. Disputes over eligibility often arise when the IRS believes the property may not meet the principal residence requirements or when documentation is insufficient to confirm residency.
Without proper documentation or clarification, taxpayers may face substantial additional tax liability and penalties.

- Accuracy-related penalty proposed: $43,370

Proving Eligibility for the Section 121 Home Sale Exclusion
Attorney Julia Salzman conducted a detailed review of the client’s records to evaluate whether the taxpayer qualified for the Section 121 exclusion.

The IRS withdrew the proposed assessment, eliminating the taxpayer’s additional liability.
Why Proper Residency Documentation Matters in IRS Home Sale Audits
Disputes involving the principal residence exclusion can lead to significant proposed tax liabilities if eligibility is questioned. Proper documentation and timely advocacy can be critical in demonstrating compliance with Section 121 requirements.
Each situation depends on the taxpayer’s specific facts and records, but early evaluation and clear documentation can help resolve these issues efficiently and avoid unnecessary penalties or assessments.
