Investing Tax Topics

Direct Answer

This cluster covers U.S. investment tax mechanics including capital gains holding periods, short-term vs long-term tax rate differences, and how account type affects tax treatment. Each guide covers a specific tax rule, verified against current IRS guidance, without providing personalized tax advice.

What is the difference between short-term and long-term capital gains?

Short-term capital gains apply to assets held for one year or less and are taxed at ordinary income tax rates, which range from 10% to 37% depending on total taxable income. Long-term capital gains apply to assets held for more than one year and are taxed at preferential rates of 0%, 15%, or 20% for most assets, depending on income.

The holding period begins the day after the purchase date and ends on the sale date. The rate difference between short-term and long-term treatment can be substantial: a top-bracket investor pays 37% on short-term gains but 20% on long-term gains, a 17-percentage-point difference before considering the net investment income tax. Holding period awareness is a basic component of tax-efficient investing.

How does the wash sale rule affect investment losses?

The wash sale rule (IRC Section 1091) disallows a capital loss deduction when you sell a security at a loss and purchase the same or a substantially identical security within 30 days before or after the sale. The disallowed loss is added to the cost basis of the replacement security, deferring rather than permanently eliminating the tax benefit.

The rule applies to stocks, bonds, ETFs, and mutual funds. Substantially identical generally means the same security, though switching between two different S&P 500 index funds from different issuers may avoid the rule depending on facts and circumstances. Cryptocurrencies are not currently subject to wash sale rules under existing IRS guidance, though legislative proposals have periodically sought to extend coverage.
