Marginal Tax Rates

Marginal tax rates refer to the tax rate applied to the last dollar of income earned. As income increases, it may fall into higher tax brackets, meaning the additional income is taxed at a higher percentage.

For traders, understanding marginal tax rates is critical when deciding between different tax treatments, such as capital gains versus ordinary income. If a trader is in a high tax bracket, they may prefer long-term capital gains rates, which are typically lower.

Conversely, if they have significant losses, they may prefer the ability to offset ordinary income through a Section 475 election. Knowing one's marginal rate helps in making informed decisions about tax-efficient trading and financial planning.
