U.S. corporate and business tax
C corporations generally pay federal corporate income tax on taxable profits. Pass-through entities (partnerships, S corporations, many LLCs) often push income to owners’ personal returns instead.
Entity choice shapes the tax path
A C corporation is a separate taxpayer. Pass-through businesses typically report profits on Schedule K-1 style statements that owners include on individual returns. Entity elections, ownership limits, and state franchise or entity-level taxes can matter as much as the headline federal corporate rate.
Profits, distributions, and double-tax intuition
Corporate education often contrasts tax at the company level with tax again when dividends reach shareholders. Pass-through models aim to tax once at owner rates - but self-employment tax, basis tracking, and state rules still apply. Public company investors usually experience corporate tax only indirectly through after-tax earnings.
What stock investors should notice
Listed equities are usually shares of corporations. Company-level tax changes can affect earnings and valuations, but your personal tax on dividends and capital gains is a separate layer covered in the investment topics.
Common mistakes
- Assuming every “LLC” is taxed the same way without checking the election.
- Confusing corporate tax rate headlines with the tax you owe on personal brokerage dividends.

- Tax Loss Harvesting Explained for Stock InvestorsTax loss harvesting means selling investments at a loss in a taxable account to offset capital gains (and sometimes a slice of ordinary income), then staying invested without triggering wash-sale or anti-avoidance rules. It helps most when you already have gains to offset - not as a reason to wreck a long-term plan.
- Capital Gains Tax on Stocks: Investor OverviewCapital gains tax (CGT) generally applies when you sell shares or ETFs for more than your cost basis. Rates, allowances, and holding-period rules vary by country - start here for the shared math, then open a StockWatch country CGT desk or country guide before you file.
- Crypto Tax Basics for InvestorsMost tax systems treat crypto like property for investors: selling, swapping, or spending can realize a gain or loss, and staking or airdrop rewards may look like income. Rules differ sharply by country - use this guide to frame the events, then open a capital-gains desk for your residency.
- Tax-Advantaged Accounts for Investors (IRA, 401k, ISA & More)Tax-advantaged accounts change when and how investment income is taxed: deferral inside pensions, tax-free growth in some wrappers, or employer plans with contribution limits. Names differ (401(k), IRA, ISA, TFSA, SIPP) - the design pattern is similar, and taxable brokerages still matter for overflow capital.
- Tax Loss Harvesting in the United StatesIn the U.S., tax loss harvesting usually means selling losers in a taxable account to offset capital gains - and sometimes up to $3,000 of ordinary income - while watching the wash-sale rule. This guide frames the pattern; confirm current IRS rules and your broker reports before filing.
- Capital Gains Tax on Stocks in the United StatesIn a U.S. taxable account, selling shares above your basis typically creates a capital gain taxed as short-term or long-term depending on holding period. Rates, netting, and forms change - use this as a map, then open the U.S. desk and IRS materials for the year you file.
- Wash-Sale Rule Explained for Stock InvestorsA wash sale generally means you sold at a loss and bought the same or a substantially identical security too close to that sale - so the loss may be disallowed or deferred. The textbook story is U.S.-centric; other markets use different rules. Use this guide before year-end harvesting.
- Roth vs Traditional IRA Basics for InvestorsTraditional IRA contributions may be deductible now with taxable withdrawals later; Roth contributions are after-tax with qualified withdrawals potentially tax-free. Eligibility, limits, and conversions are year-specific. Use this vocabulary guide, then the U.S. accounts desk.
