How to find out how much a business makes depends almost entirely on what kind of business it is. Public companies disclose audited financials to the Securities and Exchange Commission, and you can read them for free. Nonprofits file annual tax returns that anyone can pull up. Private companies guard their numbers, but pieces of their finances leak out through government contracts, state filings, credit reports, and court records, and you can usually assemble a credible estimate from those pieces plus industry benchmarks.
Start by identifying the entity. The path forward branches sharply from there.
Public Companies: Read the SEC Filings
If the business trades on a stock exchange, nearly everything is available for free through EDGAR, the SEC’s Electronic Data Gathering, Analysis, and Retrieval system.1U.S. Securities and Exchange Commission. About EDGAR Search by company name or ticker symbol and pull up years of financial history.2U.S. Securities and Exchange Commission. Search Filings
The single most useful document is the annual report on Form 10-K. It gives a comprehensive picture of the business and includes audited financial statements prepared by an independent accountant.3Investor.gov U.S. Securities and Exchange Commission. Form 10-K Inside, the income statement lists total revenue, operating expenses, and net profit for the fiscal year. The balance sheet breaks down assets, liabilities, and shareholder equity at a specific date. The Management’s Discussion and Analysis section explains, in the company’s own words, why revenue moved the way it did.
Between annual reports, look for two other forms. The 10-Q covers quarterly results. The 8-K is triggered by significant events between scheduled filings, including major acquisitions or asset sales, quarterly earnings announcements, large new financial obligations, layoffs or restructuring charges, and material write-downs on assets like goodwill.4U.S. Securities and Exchange Commission. Form 8-K Current Report If you need the freshest picture of a public company’s finances, the most recent 10-Q or 8-K usually beats a 10-K that could be nearly a year old.
Nonprofits: Pull the Form 990
Nonprofits sit in an unusual place. They’re not publicly traded, but federal tax law makes most tax-exempt organizations file annual information returns that are open to the public. If the entity you’re researching is a charity, foundation, trade association, or other 501(c) group, its finances are often more accessible than those of a for-profit private company.
The key document is IRS Form 990. It reports total revenue, total expenses, net assets, and compensation paid to officers, directors, and the five highest-paid employees.5Internal Revenue Service. Instructions for Form 990 Return of Organization Exempt From Income Tax Private foundations file Form 990-PF instead, with similar financial detail plus grant information. Very small organizations with annual gross receipts normally at or below $50,000 file a simplified electronic notice called Form 990-N that contains little financial data.6Internal Revenue Service. Search for Tax Exempt Organizations
The IRS Tax Exempt Organization Search tool lets you look up an organization’s status and access its returns.6Internal Revenue Service. Search for Tax Exempt Organizations Third-party sites such as ProPublica’s Nonprofit Explorer often make the same filings easier to browse and drop summary financials at the top of each profile.
Private Companies: Piece It Together
Privately held companies don’t file financial statements with any public agency. There’s no single database to check. Instead, you build a picture from records that other laws and business relationships push into public view, then cross-check that picture against industry benchmarks.
Government Contract Awards
If a private business does work for the federal government, the contract value becomes public information the moment the award is made. The awardee’s name, address, and total contract value are available to anyone upon request without a FOIA filing.7Bureau of the Fiscal Service. Requesting Procurement Information
USAspending.gov tracks federal spending on contracts, grants, and loans. Filter by recipient, industry, location, and date range to find every federal dollar flowing to a company. SAM.gov provides additional detail on contract actions with an estimated value of $10,000 or more.8SAM.gov. Contract Award Data For a small firm that depends heavily on government work, these records can reveal a large share of total revenue.
State and local procurement portals work similarly. Most publish bid results and purchase orders showing what vendors were paid. These records won’t capture everything a company earns, but if you find $2 million in annual contracts for a 15-person firm, you’ve established a meaningful revenue floor. One caveat: agencies can redact proprietary cost breakdowns and losing bidders’ pricing under FOIA Exemption 4, which protects trade secrets and confidential commercial or financial information.9eCFR. 32 CFR 1662.21 – The FOIA Exemption 4: Trade Secrets and Confidential Commercial or Financial Information
State Business Filings, UCC Liens, and Licenses
Every corporation, LLC, and limited partnership files periodic reports with the Secretary of State in its state of formation. These filings usually list officers, directors, and the registered agent rather than dollar figures. But some states set filing fees based on authorized shares or reported total assets, and states that impose franchise taxes based on net worth or gross assets create a more direct link between the filing and the company’s size.
UCC-1 financing statements are another useful trail. When a business pledges assets as collateral for a loan, the lender files a UCC-1 with the state to establish its claim. The filing shows the debtor, the lender, a description of the collateral, and the date. Collateral descriptions range from specific equipment identified by serial number to blanket claims covering all inventory, accounts receivable, and equipment. Multiple active UCC filings suggest the company uses asset-based financing heavily and has revenue streams sufficient to service that debt.
Regulated businesses, including construction firms, healthcare providers, and financial services companies, hold licenses that often require proof of bonding or insurance. Coverage levels correlate with the size of projects the company can legally handle. A contractor bonded for $5 million is operating at a different scale than one bonded for $100,000. Licensing boards publish these records, and while they don’t show revenue directly, the bonding thresholds proxy for capacity and likely income range.
Commercial Credit Reports
Commercial credit bureaus collect payment history, legal filings, and financial data that private companies rarely disclose on their own. Dun & Bradstreet is the most established and assigns a PAYDEX score from 1 to 100 reflecting how consistently a business pays its bills, with 80 or above considered low risk.10Dun & Bradstreet. Business Credit Scores and Ratings – Understanding the D&B PAYDEX Score, SER Rating, and More A detailed D&B report often includes estimated annual sales, employee counts, and payment trend data that together outline the company’s trajectory.
Experian Business and Equifax Small Business offer similar products. A single report typically costs a fee, with pricing depending on the provider and the depth of analysis. Bloomberg Terminal and Refinitiv, aimed at professional financial analysts, carry expensive subscriptions but combine shipping records, property assessments, and industry comparisons to model private company revenue with surprising precision.
Treat the revenue estimates in these reports as educated guesses, not audited figures. The underlying data comes from vendors, public records, and the business’s own voluntary reporting.
Court Records
Lawsuits and bankruptcies can force open records that a company would never release voluntarily. If the business has been in litigation, the court file may contain the most detailed and verified financial data available anywhere outside the company’s own books.
A company filing for Chapter 11 or Chapter 7 must submit detailed schedules of assets, liabilities, current income, and expenditures.11Office of the Law Revision Counsel. 11 USC App Rule 1007 – Lists, Schedules, and Statements; Time Limits These filings often include recent tax returns and profit-and-loss statements. Bankruptcy records are available through PACER, which covers federal district, bankruptcy, and appellate courts.12PACER: Federal Court Records. What Information Is Available Through PACER Access costs $0.10 per page with a $3.00 cap per document, and PACER waives fees entirely if your charges total $30 or less in a calendar quarter.13PACER: Federal Court Records. How Much Does It Cost to Access Documents Using PACER A one-time research project may cost you nothing.
Civil litigation produces similar disclosures. Breach-of-contract suits, shareholder disputes, and business divorce cases regularly generate tax returns, internal audits, and accounting ledgers during discovery. Under Federal Rule of Civil Procedure 34, a party can request production of documents within the scope of permissible discovery.14Legal Information Institute. Federal Rule of Civil Procedure 34 – Producing Documents, Electronically Stored Information, and Tangible Things, or Entering onto Land, for Inspection and Other Purposes Unless the court seals them, documents entered into evidence become public record. Divorce cases involving business owners are particularly revealing, since professional appraisers value the company as a marital asset and their reports end up in the file. Judges tend to treat tax returns as presumptively private, so those require a showing of relevance and unavailability from other sources.
Estimating From Proxies
When direct data isn’t available, work from observable facts and industry benchmarks. This is what analysts do every day.
The most common method starts with employee headcount, drawn from job postings, professional networking profiles, or the company’s own website. The Census Bureau’s North American Industry Classification System (NAICS) categorizes businesses by industry.15U.S. Census Bureau. North American Industry Classification System – NAICS Once you have the company’s NAICS code, you can find published industry averages for revenue per employee. A 50-person company in a sector that averages $200,000 per worker generates roughly $10 million a year. Not exact, but in the right order of magnitude.
Physical footprint works as a second proxy. Retail businesses are routinely benchmarked by sales per square foot; if you can identify store size from commercial real estate listings or property records, you can multiply by the industry average. Warehousing and logistics firms can be estimated from facility size, fleet count, or shipping volume. Trade associations and the Census Bureau’s Economic Census publish median profit margins and revenue distributions by industry, which help you convert a revenue estimate into an operating income range.
Where the Line Is
Most of what’s described above is entirely legal. You’re using public records, published data, and commercially available reports. But there is a line.
A company’s internal financials, customer lists, pricing strategies, and cost structures can qualify as trade secrets if the company takes reasonable steps to keep them confidential and the information has independent economic value from not being publicly known. The federal Defend Trade Secrets Act allows the company to sue for actual damages and unjust enrichment, and willful and malicious misappropriation can result in exemplary damages up to twice the compensatory award, plus attorney’s fees.16Office of the Law Revision Counsel. 18 U.S. Code 1836 – Civil Proceedings Don’t bribe employees for internal numbers, hack systems, or trick anyone into handing over confidential data.
If your research involves a public company and you come across material nonpublic information, trading on it is illegal. Information is material if a reasonable investor would consider it important to a buy or sell decision, and nonpublic if it hasn’t been disseminated to the general investing public.17U.S. Securities and Exchange Commission. Selective Disclosure and Insider Trading The civil penalty can reach three times the profit gained or loss avoided.18Office of the Law Revision Counsel. 15 U.S. Code 78u-1 – Civil Penalties for Insider Trading The rule reaches anyone who trades while aware of material information received in breach of a duty of trust or confidence, not only corporate insiders.
Gather freely from public records, commercial databases, and observable business activity. Just don’t take confidential data, and don’t trade stocks on nonpublic information you weren’t supposed to have.
