Home-sale losses cannot be deducted because personal residences are not income-producing assets.

Evidence

Meanwhile, the tax treatment for home-sale losses has never changed, bound by Congress’s restrictive definitions on personal versus business or investment income and deductions. Income is considered income “from whatever source derived” and taxed (or not) accordingly, but losses are only deductible if they are connected to trade or business property or assets held for the production of income—like stock. Personal assets—like your personal residence—are not eligible for loss deductions, so if you sell your home at a loss, no deduction for you. — Dorothy A. Brown, The Whiteness of Wealth, 197

• DEFINE: Precisely defines the asymmetric tax treatment: gains tax-free, losses non-deductible, because only trade/business losses qualify.
• SEED: The gain-taxed-free/loss-not-deductible asymmetry is a crisp, quotable mechanism for an essay on race-neutral tax provisions that widen the wealth gap.
• DEEPTHINKING: The asymmetry — gains from housing exempt, losses from housing never deductible — is a single elegant code structure doing enormous racial work, arguably the chapter’s core mechanism.
