A registered investment company is a pooled investment vehicle that collects money from many investors, invests it in a portfolio of securities managed by a professional adviser, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940. Mutual funds, closed-end funds, exchange-traded funds, and unit investment trusts all fall into this category. The reason the label matters is tax: a registered investment company that meets the requirements of Subchapter M of the Internal Revenue Code can pass its income through to shareholders without paying corporate tax on it first.
When a Company Has to Register
The Investment Company Act treats a company as an investment company if it is primarily in the business of investing in securities, or if more than 40 percent of its total assets (excluding government securities and cash) consist of investment securities.1Office of the Law Revision Counsel. 15 USC 80a-3 – Definition of Investment Company Cross that line while operating in interstate commerce and the company must register with the SEC. Investment securities for this purpose leave out government securities, securities of employee securities companies, and securities of majority-owned subsidiaries that are not themselves investment companies.
Registration brings a package of duties: public disclosure documents, governance requirements, and limits on borrowing, share pricing, and manager compensation. The goal is to give retail investors the same visibility and protections that large institutions can negotiate on their own.
Who Is Excluded
Several kinds of businesses that look like investment companies are already regulated elsewhere and stay outside the definition. Banks, insurance companies, and broker-dealers are excluded, along with small loan companies, industrial banks, and companies whose primary business involves receivables or real estate mortgages.1Office of the Law Revision Counsel. 15 USC 80a-3 – Definition of Investment Company Holding companies whose subsidiaries operate in those regulated fields are excluded too.
Private funds also sit outside the framework. A fund with no more than 100 beneficial owners (or 250 for a qualifying venture capital fund) that does not make a public offering does not have to register.1Office of the Law Revision Counsel. 15 USC 80a-3 – Definition of Investment Company That is how hedge funds and private equity funds avoid the Act. What is left, the registered universe, is the set of investment vehicles ordinary investors actually buy.
The Types of Registered Investment Companies
The statute groups registered investment companies into three legal classes: face-amount certificate companies, unit investment trusts, and management companies.2Office of the Law Revision Counsel. 15 USC 80a-4 – Classification of Investment Companies Face-amount certificate companies, which sold contracts promising a fixed sum at maturity, are effectively extinct. The SEC groups the surviving universe into mutual funds, closed-end funds, and UITs.3U.S. Securities and Exchange Commission. Investment Companies Management companies further split into open-end companies (mutual funds) and closed-end companies. ETFs are registered as either open-end companies or UITs.
Mutual Funds (Open-End Companies)
When you buy shares of a mutual fund, the fund issues new shares. When you sell, the fund redeems them. Every purchase and redemption happens at the fund’s net asset value per share, calculated once each business day after the major U.S. exchanges close.4eCFR. 17 CFR 270.22c-1 – Pricing of Redeemable Securities Because shares are continuously issued and redeemed, the number outstanding changes daily. You can always sell back to the fund at NAV.
Closed-End Funds
A closed-end fund raises a fixed amount of capital in an IPO and then lists its shares on a stock exchange. After the IPO it does not issue new shares or redeem existing ones. Buyers and sellers trade with each other on the exchange, so the market price can drift above NAV (a premium) or below (a discount). Persistent discounts are common with closed-end funds, and experienced investors typically look at that price gap before buying in.
Unit Investment Trusts
A UIT holds a fixed portfolio of securities for a set period, with no active management after launch. Units can be redeemed at NAV, but the portfolio itself does not change. When the trust reaches its termination date, the remaining assets are sold and the proceeds distributed to unitholders.
Exchange-Traded Funds
ETFs are registered under one of the existing categories but trade on exchanges throughout the day, like closed-end funds. Most use an authorized participant mechanism: large institutions create or redeem big blocks of ETF shares in exchange for the underlying securities, keeping the market price close to NAV. That in-kind process also generates fewer taxable events than a traditional mutual fund, which is a large part of why the format has grown so quickly.
How RIC Taxation Works Under Subchapter M
An ordinary C corporation pays 21 percent federal tax on its income, and shareholders pay again on the dividends. Subchapter M erases that second layer for a fund that qualifies as a regulated investment company by letting the fund deduct the dividends it pays out. Only the shareholders pay tax on the income. To keep that treatment, a fund has to pass three continuous tests.
The Income Test
At least 90 percent of the fund’s gross income each year must come from dividends, interest, payments from securities lending, and gains on the sale of stocks, securities, or foreign currencies.5Office of the Law Revision Counsel. 26 USC 851 – Definition of Regulated Investment Company Income from options, futures, and forward contracts on those assets counts as well, and a limited amount can come from qualifying publicly traded partnerships. Commodities, cryptocurrencies, and physical metals do not qualify, which is why traditional mutual funds rarely hold those assets directly. A fund that drifts above the 10 percent ceiling for non-qualifying income faces a punitive tax and risks losing RIC status.
The Diversification Test
At the close of each quarter, at least 50 percent of the fund’s total assets must sit in cash, government securities, securities of other RICs, or other securities where no single issuer represents more than 5 percent of total assets or more than 10 percent of that issuer’s voting securities.6Internal Revenue Service. Revenue Procedure 2004-28 Separately, no more than 25 percent of total assets may be invested in the securities of any single issuer (other than government securities or other RICs), or in two or more controlled issuers in the same or a related business. Together, these rules keep a fund from concentrating too heavily in a handful of names.
The Distribution Requirement
A RIC must distribute at least 90 percent of its investment company taxable income (ordinary income plus net short-term capital gains) to shareholders each year.7Office of the Law Revision Counsel. 26 USC 852 – Taxation of Regulated Investment Companies If it meets that threshold, corporate tax applies only to any income the fund retains. The income that flows through keeps its character: ordinary dividends stay ordinary, tax-exempt interest stays tax-exempt, and capital gains are reported as capital gains on Form 1099-DIV.8Internal Revenue Service. Instructions for Form 1099-DIV
Undistributed net capital gains are taxed at the fund level under the regular corporate rate.9Office of the Law Revision Counsel. 26 USC 852(b) – Method of Taxation of Companies and Shareholders Most funds prefer to pass those gains through rather than absorb the tax. If a fund misses a year-end distribution, it can still count certain dividends paid in the following year toward the prior year’s requirement, provided it declares the dividend by the extended due date of its tax return and pays it within twelve months of the close of the taxable year.10Office of the Law Revision Counsel. 26 USC 855 – Dividends Paid by Regulated Investment Company After Close of Taxable Year
The 4 Percent Excise Tax
A separate excise tax runs on a calendar-year basis. If a fund does not distribute enough of its income and capital gains by December 31, it owes 4 percent on the shortfall.11Internal Revenue Service. Instructions for Form 8613 The required distribution for this purpose is higher than the 90 percent income tax test. Fund managers track the deadline carefully because the tax is avoidable and simply erodes returns.
What Happens If a Fund Loses RIC Status
Failing the income test, the diversification test, or the distribution requirement can strip a fund of pass-through treatment. The fund would then pay 21 percent federal tax on its net income, and shareholders would still owe tax on their dividends. That is the double taxation Subchapter M was written to prevent. In practice, losing RIC status usually triggers heavy redemptions and often ends in liquidation. The IRS can waive certain failures for reasonable cause, but it is not a problem a fund manager wants to have to explain to investors.
Investor Protections Built Into the Structure
Several requirements under the Investment Company Act shape what registration actually means for the people buying shares.
Board independence. No more than 60 percent of a fund’s board may consist of “interested persons,” so at least 40 percent must be independent of the adviser and other affiliates.12Office of the Law Revision Counsel. 15 USC 80a-10 – Affiliations or Interest of Directors, Officers, and Employees SEC rules push the practical bar higher: independent directors must make up a majority of the board for any fund relying on certain common exemptive rules, which covers almost every fund an ordinary investor can buy.13Securities and Exchange Commission. Role of Independent Directors of Investment Companies Independent directors approve the advisory contract, review fees, and act as the internal check on conflicts between the manager and the shareholders.
Custody. Portfolio securities and cash must be held by a qualified custodian separate from the adviser or distributor. If the adviser fails, the fund’s assets sit in a separate account at a bank or trust company. The custodian provides regular statements to the board, giving auditors an independent paper trail.
Compliance officer. Every registered investment company must designate a chief compliance officer, and the board (including a majority of independent directors) must approve the appointment and compensation.14eCFR. 17 CFR 270.38a-1 – Compliance Procedures and Practices of Certain Investment Companies Removal requires board approval, insulating the role from adviser pressure.
Borrowing limits. A closed-end fund issuing debt must keep asset coverage of at least 300 percent, meaning total assets of at least three times outstanding borrowings. If it issues preferred stock instead, coverage drops to 200 percent.15Office of the Law Revision Counsel. 15 USC 80a-18 – Capital Structure of Investment Companies Open-end funds cannot issue any class of senior security. Their only leverage option is a bank loan, and the fund must have 300 percent asset coverage; if coverage falls below that, it has three business days to bring borrowings back in line.
Forward pricing. Open-end funds and UITs must price every purchase and redemption at the next-computed NAV.4eCFR. 17 CFR 270.22c-1 – Pricing of Redeemable Securities NAV must be calculated at least once each business day at a time the board sets, most commonly after the U.S. exchanges close at 4 p.m. Eastern. When market prices are not readily available, the board (or a valuation designee it oversees) determines fair value.16eCFR. 17 CFR 270.2a-5 – Fair Value Determination Portfolio managers cannot determine or substantially influence the fair values assigned to the securities they manage.
Where to Find a Fund’s Disclosures
Registered investment companies must send shareholders prospectuses, annual reports, and semi-annual reports.17Securities and Exchange Commission. Shareholder Reports and Quarterly Portfolio Disclosure of Registered Management Investment Companies The prospectus lays out investment objectives, strategies, risks, and fees. Annual reports include management’s discussion of performance and audited financial statements. Semi-annual reports are due within 60 days of the end of the reporting period. Funds also file their proxy voting records on SEC Form N-PX, showing how they voted on every shareholder proposal for portfolio securities. All of these filings are public through the SEC’s EDGAR system, so you can read them before committing money.
