Can an S Corp Invest in Stocks? Taxation & Status Rules

S corporations are a popular business structure, offering a blend of corporate liability protection and pass-through taxation. These entities can engage in various financial activities, including investing in stocks. While S corporations can hold investments, understanding the tax implications and specific rules is important for maintaining their tax status.

Understanding S Corporation Investment in Stocks

An S corporation is generally permitted to invest in stocks. The primary characteristic of an S corporation is its pass-through tax status. This means that the corporation itself does not pay federal income tax on its profits, including gains from investments.

Income, losses, deductions, and credits generated by the S corporation are passed through directly to the shareholders. Each shareholder then reports their proportionate share of these items on their personal income tax return. Shareholders are taxed on these profits in the current year, even if the S corporation retains them.

Taxation of Investment Income

Different types of investment income flowing through an S corporation are taxed to shareholders based on their character. Dividends, interest, and capital gains from stock sales retain their original character as they pass through to the shareholders’ personal tax returns. This determines how these income items are ultimately taxed.

Qualified dividends, from shares held for a specified period, are subject to preferential tax rates at the shareholder level. These rates can be 0%, 15%, or 20%, depending on the shareholder’s income bracket. Ordinary dividends, along with interest income and short-term capital gains (from assets held one year or less), are taxed at the shareholder’s ordinary income tax rates, which can be significantly higher. Long-term capital gains, derived from assets held for more than one year, also receive preferential tax rates, 0%, 15%, or 20%.

Maintaining S Corporation Status

Maintaining S corporation status requires adherence to specific rules, particularly concerning passive investment income if the corporation has accumulated earnings and profits (AE&P) from prior C corporation years. AE&P would have been accumulated when the entity operated as a C corporation, or inherited from an acquired C corporation. If an S corporation with C corporation AE&P has passive investment income exceeding 25% of its gross receipts for three consecutive taxable years, its S election can be terminated.

Passive investment income includes gross receipts from royalties, rents, dividends, interest, annuities, and gains from the sale or exchange of stock or securities. This test aims to prevent S corporations with significant C corporation AE&P from primarily operating as passive investment vehicles. If this threshold is exceeded, the S corporation may also be subject to a corporate-level tax on its excess net passive income at the highest corporate income tax rate.

Reporting Investment Activity and Shareholder Basis

An S corporation reports its financial activities, including investment income, on Form 1120-S. This form details the corporation’s income, deductions, gains, and losses. An important part of this reporting is Schedule K-1 (Form 1120-S), which is issued to each shareholder.

Schedule K-1 provides each shareholder with their proportionate share of the corporation’s income, deductions, credits, and other items, including investment income such as interest, ordinary dividends, qualified dividends, and capital gains. Shareholders use this information to prepare their individual income tax returns. Investment income and losses also affect a shareholder’s stock basis in the S corporation. Income items increase their basis, while losses and distributions decrease it. This basis calculation is important for determining the taxability of distributions and the deductibility of losses.
