10-K vs. 10-Q: Key Differences Every Public Company Should Know

Introduction

A 10-K is an annual report filed once per year covering a company's full financial performance, audited statements, and risk disclosures. A 10-Q is a quarterly report filed three times per year with unaudited financials and abbreviated disclosures. Both are required by the SEC for public companies. The 10-K carries more depth and stricter deadlines; the 10-Q keeps investors updated between annual filings. Understanding both is foundational to SEC compliance.

Category	Form 10-K	Form 10-Q
Filing frequency	Filed annually after the fiscal year ends	Filed after the first three fiscal quarters (Q1–Q3)
Purpose	Comprehensive annual disclosure of financial performance, operations, and risk	Quarterly update on financial performance and material changes
Audit requirement	Audited financial statements	Reviewed, but not audited, financial statements
Filing deadline	60 days (large accelerated), 75 days (accelerated), or 90 days (non-accelerated) after fiscal year-end	40 days (large accelerated and accelerated) or 45 days (non-accelerated) after quarter-end
Scope of disclosures	Full MD&A, business overview, risk factors, legal proceedings, and audited financial statements	Abbreviated MD&A and updates to material changes since the previous filing
SOX certifications	Sections 302 and 906 certifications, plus annual internal control assessment where applicable	Section 302 certification only
Inline XBRL (iXBRL)	Required	Required
When required	Once each fiscal year	After Q1, Q2, and Q3 (Q4 is included in the Form 10-K)

Preparing SEC filings requires understanding when a Form 10-K and Form 10-Q are required, what each filing must include, and how they support ongoing SEC compliance. For compliance teams, general counsel, investor relations professionals, and capital markets attorneys, understanding the 10-K vs 10-Q distinction is essential for planning reporting workflows, coordinating reviews, and meeting regulatory filing deadlines.

Organizations responsible for preparing these filings also need reliable processes that improve consistency and support efficient review. As SEC filing software continues to evolve, precedent-based workflows can help streamline drafting and review while maintaining traceability to source filings and supporting auditable reporting processes.

What Is a 10-K?

A Form 10-K is an annual report filing that most U.S. public companies must submit to the U.S. Securities and Exchange Commission after the end of each fiscal year. It is the company's most comprehensive periodic filing, providing audited financial statements and required disclosures that support regulatory reporting, corporate transparency, and ongoing SEC compliance.

At a high level, a Form 10-K includes:

• Audited financial statements
• Management's Discussion and Analysis (MD&A)
• Business and property descriptions
• Risk factors
• Legal proceedings
• Corporate governance and other required SEC disclosures

Together, these disclosures provide a comprehensive record of a company's financial performance, operating results, and material risks for the fiscal year.

A Form 10-K should not be confused with an annual report to shareholders. Although both documents may contain similar financial information, a Form 10-K is a formal SEC filing that follows prescribed disclosure requirements, while an annual report to shareholders is a broader shareholder communication that may include executive letters, branding, and other investor-focused content. Some public companies combine both documents, but the Form 10-K must still satisfy all applicable SEC reporting requirements.

What Is a 10-Q?

A Form 10-Q is a quarterly report that most U.S. public companies must file with the U.S. Securities and Exchange Commission after the first three fiscal quarters (Q1–Q3). Unlike a Form 10-K, it provides an interim update on a company's financial performance and material developments since the most recent annual report filing, supporting ongoing SEC compliance between annual reporting cycles.

At a high level, a Form 10-Q includes:

• Reviewed, but unaudited, financial statements
• Updated Management's Discussion and Analysis (MD&A)
• Material changes to previously disclosed risk factors
• Updates on legal proceedings and other reportable events
• Other required interim disclosures

Because a Form 10-Q builds on information already reported in the Form 10-K, many disclosures are abbreviated rather than presented in full. For example, it does not include audited financial statements, a complete business description, or a full discussion of risk factors unless material changes have occurred.

Companies file a Form 10-Q after the first, second, and third fiscal quarters only. There is no separate fourth-quarter Form 10-Q because fourth-quarter financial results and year-end disclosures are incorporated into the annual Form 10-K.

10-K vs. 10-Q: Key Differences at a Glance

A Form 10-K and a Form 10-Q are both required periodic filings submitted to the U.S. Securities and Exchange Commission, but they serve different reporting purposes. The table below summarizes the operational differences that public company reporting teams should understand.

Category	Form 10-K	Form 10-Q
Filing frequency	Filed annually after the fiscal year ends	Filed after the first three fiscal quarters (Q1–Q3)
Purpose	Comprehensive annual disclosure	Interim update on financial performance and material developments
Financial statements	Audited	Reviewed, but not audited
Filing deadline	60 days (large accelerated), 75 days (accelerated), or 90 days (non-accelerated) after fiscal year-end	40 days (large accelerated and accelerated) or 45 days (non-accelerated) after quarter-end
MD&A scope	Full discussion of annual financial results, trends, and known uncertainties	Updates focused on material changes since the previous annual filing
Risk factors	Complete disclosure of material risk factors	Material changes to previously disclosed risk factors
SOX certifications	Sections 302 and 906 certifications, plus annual internal control assessment where applicable	Section 302 certification only
Inline XBRL (iXBRL)	Required	Required
Overall scope	Comprehensive annual filing covering the full fiscal year	Abbreviated quarterly filing that supplements the Form 10-K

The primary differences between 10-K and 10-Q are the scope of disclosures, audit requirements, and filing frequency. A Form 10-K establishes the company's annual disclosure record with audited financial statements and comprehensive disclosures, while a Form 10-Q provides abbreviated quarterly updates using reviewed interim financial statements.

From an operational perspective, the Form 10-K generally requires broader coordination across finance, legal, investor relations, and compliance teams because it includes annual financial reporting, business disclosures, and internal control reporting. The Form 10-Q follows a more focused reporting process but still requires timely disclosure of material changes to support ongoing SEC compliance.

Filing Deadlines — What Every Public Company Needs to Know

Form 10-K and Form 10-Q filing deadlines are based on a company's filer status under U.S. Securities and Exchange Commission rules. Compliance, legal, and finance teams should incorporate these regulatory timelines into their capital markets filing workflows to support timely drafting, review, executive certifications, and Inline XBRL (iXBRL) preparation.

Filer Type	Form 10-K Deadline	Form 10-Q Deadline
Large Accelerated Filer	60 days after fiscal year-end	40 days after quarter-end
Accelerated Filer	75 days after fiscal year-end	40 days after quarter-end
Non-Accelerated Filer	90 days after fiscal year-end	45 days after quarter-end

These deadlines are measured from the end of the applicable reporting period. Form 10-Q is filed after the first three fiscal quarters only because fourth-quarter financial results and year-end disclosures are incorporated into the annual Form 10-K.

Companies that change their fiscal year may need to file transition reports using Form 10-KT or Form 10-QT. These filings bridge non-standard reporting periods and help maintain continuous SEC reporting during a fiscal-year transition.

Missing a filing deadline may result in delinquent filer status and can affect eligibility to use certain short-form registration statements, including Form S-3. Compliance teams should verify filing deadlines against current SEC guidance and allocate sufficient time for legal review, auditor coordination, executive certifications, Inline XBRL tagging, and final submission.

What the 10-K Includes That the 10-Q Doesn't

Although both filings are required for ongoing SEC compliance, a Form 10-K contains broader disclosure requirements than a Form 10-Q. The Form 10-K serves as a company's comprehensive annual report filing, while the Form 10-Q provides abbreviated quarterly updates focused on material changes since the most recent annual filing. Understanding these scope differences helps legal, finance, and compliance teams prepare accurate periodic reports.

Compared with a Form 10-Q, a Form 10-K includes:

• Audited financial statements. A Form 10-K includes annual financial statements audited by an independent registered public accounting firm. A Form 10-Q includes interim financial statements that are reviewed, but not audited.
• Complete risk factor disclosures. A Form 10-K requires a comprehensive discussion of material risk factors. A Form 10-Q requires disclosure only of material changes to previously reported risk factors.
• Comprehensive business disclosures. A Form 10-K includes detailed information about the company's business, properties, and legal proceedings. A Form 10-Q updates these disclosures only when material changes occur.
• Full Management's Discussion and Analysis (MD&A). The Form 10-K discusses annual operating results, liquidity, capital resources, and known trends or uncertainties. A Form 10-Q provides an abbreviated MD&A focused on significant quarterly changes.
• Annual internal control reporting. A Form 10-K includes Sarbanes-Oxley (SOX) Sections 302 and 906 certifications and, where applicable, management's annual assessment of internal control over financial reporting. A Form 10-Q requires Section 302 certification only.

These disclosure differences establish the Form 10-K as the company's primary annual SEC filing, while the Form 10-Q supplements that record through abbreviated quarterly reporting.

Do All Public Companies Have to File Both?

In most cases, yes. U.S. public companies subject to the U.S. Securities and Exchange Commission reporting requirements under the Securities Exchange Act of 1934 generally must file both Form 10-K and Form 10-Q. The Form 10-K is filed annually after the fiscal year-end, while the Form 10-Q is filed after each of the first three fiscal quarters to support ongoing SEC compliance.

The primary exception is foreign private issuers, which generally file Form 20-F as their annual report and furnish Form 6-K for material information during the year instead of filing Forms 10-K and 10-Q. Other reporting accommodations may apply in limited circumstances under SEC rules, but unless an exemption applies, domestic public companies should expect to prepare both filings as part of their annual reporting obligations.

How AI-Assisted Review Changes the Workflow for Both Forms?

Preparing a Form 10-K typically requires the most time because it combines comprehensive annual disclosures, audited financial statements, prior-year carryforwards, and multiple review cycles across legal, finance, compliance, investor relations, and external auditors. These workflows rely heavily on precedent, making them well suited to precedent-based AI-assisted drafting and review that benchmarks current disclosures against prior SEC filings, improves consistency, and maintains traceability throughout the review process.

Form 10-Q workflows are more streamlined but still require careful comparison with the most recent Form 10-K. Because quarterly reports update only material changes rather than restating annual disclosures, reporting teams spend much of their review time validating consistency, identifying new disclosures, and confirming that existing information remains accurate. Precedent-based review helps reduce manual comparison while preserving accurate, auditable reporting built on previously filed disclosures.

Organizations evaluating AI-assisted drafting and review can streamline both annual and quarterly SEC reporting workflows through structured, precedent-based processes that support efficient drafting, consistent review, and traceable, auditable outputs.

Frequently Asked Questions

What is the difference between a 10-K and a 10-Q?

A Form 10-K is an annual filing that includes audited financial statements and comprehensive disclosures about a company's business, operations, risk factors, and financial performance. A Form 10-Q is filed after the first three fiscal quarters and includes reviewed, unaudited financial statements with abbreviated disclosures focused on material changes since the most recent Form 10-K.

---

Is a 10-K the same as an annual report?

No. A Form 10-K is the official filing submitted to the U.S. Securities and Exchange Commission (SEC) and follows specific disclosure requirements. An annual report to shareholders is a separate investor communication that may include executive letters, branding, and other shareholder-focused information. Some public companies combine both into a single publication, but they remain distinct documents.

---

When is the 10-K due?

The filing deadline depends on the company's filer status. Large accelerated filers must file within 60 days, accelerated filers within 75 days, and non-accelerated filers within 90 days after the fiscal year-end. Missing these deadlines may result in delinquent filer status, increased SEC scrutiny, and loss of eligibility to use certain short-form registration statements.

---

When is the 10-Q due?

A Form 10-Q is due after each of the first three fiscal quarters. Large accelerated and accelerated filers must file within 40 days after quarter-end, while non-accelerated filers have 45 days. There is no separate fourth-quarter Form 10-Q because year-end financial results are reported in the annual Form 10-K.

---

Do small public companies have to file both?

Generally, yes. Most domestic public companies subject to SEC reporting requirements must file both Forms 10-K and 10-Q. The primary exception is foreign private issuers, which generally file Form 20-F as their annual report and furnish Form 6-K to report material information during the year instead of filing Forms 10-K and 10-Q.

---

What happens if a 10-K or 10-Q is filed late?

Late filings may result in delinquent filer status, increased SEC scrutiny, and loss of eligibility to use certain short-form registration statements, such as Form S-3. Delayed filings can also affect capital-raising activities, investor communications, and other regulatory reporting obligations until compliance is restored.

---

Does the 10-Q require an independent audit?

No. The financial statements included in a Form 10-Q are reviewed by an independent registered public accounting firm but are not audited. A Form 10-K includes audited annual financial statements, providing a higher level of assurance and more comprehensive annual disclosures.
