Final answer:
Capital losses from sales of investment assets are typically deductible for tax purposes, unlike losses from wash sales, sales of personal-use assets, or sales to related parties which are either not deductible or subject to special rules.
Step-by-step explanation:
According to IRS rules, capital losses that are deductible for tax purposes result from sales of investment assets. The sale of investment assets, such as stocks, bonds, and mutual funds, can result in a capital loss if the sale price is lower than the purchase price. This capital loss can be used to offset capital gains and potentially reduce the individual's tax liability. Wash sales, sales of personal-use assets, and sales to related parties do not usually result in deductible capital losses for tax purposes.
The deductible capital losses for tax purposes generally come from the sales of investment assets. This is because losses from the sale of investment assets, like stocks or bonds, are typically used to offset capital gains and reduce your taxable income. Conversely, wash sales, which involve selling a security at a loss and repurchasing a similar security shortly before or after, are not deductible due to the wash sale rule aimed at preventing taxpayers from claiming artificial losses. Sales of personal-use assets usually result in non-deductible losses since they are not considered investments. Lastly, losses from sales to related parties are often subject to special rules to prevent tax avoidance and may not be deductible.
