What is IRS Publication 15?
IRS Publication 15, also known as Circular E, is the official Employer's Tax Guide outlining your federal tax responsibilities for withholding, depositing, reporting, and paying employment taxes. It provides essential guidance on calculating payroll taxes including Social Security and Medicare contributions, helping you comply with federal tax laws.
This publication does not cover state or local tax obligations, so employers should consult additional resources for those requirements. Understanding ability to pay taxation principles can also clarify your tax duties.

- Tax withholding and depositing: Step-by-step instructions on calculating and submitting federal tax withholdings for employees.
- Reporting and payment: Guidelines for timely federal employment tax filings and deposits.
- Social Security and Medicare: Details on contribution rates, including the 6.2% rate for both employer and employee in 2026.
- Record-keeping: Requirements for maintaining payroll and tax records for at least four years.
- Error correction: Procedures to amend employment tax filings and deposits if mistakes occur.
How It Works
Employers use IRS Publication 15 to accurately calculate payroll tax withholdings based on employee wages and federal tax tables. Following the guide helps ensure proper withholding of federal income, Social Security, and Medicare taxes, which you then deposit according to IRS schedules.
By adhering to these procedures, you maintain compliance and avoid penalties for late or incorrect payments. The publication also assists in distinguishing between employees and independent contractors, complementing labor regulations like the Fair Labor Standards Act (FLSA).
Examples and Use Cases
IRS Publication 15 is widely used by businesses across industries to manage payroll tax responsibilities effectively:
- Airlines: Companies like Delta rely on this guide to ensure accurate withholding on employee wages across multiple states.
- Financial firms: Investment companies often refer to best bank stocks data when managing tax liabilities related to employee compensation.

Important Considerations
Keep in mind that IRS Publication 15 focuses strictly on federal employment taxes; you must separately address any state-specific withholding rules. Staying current with updates, such as changes for 2026 on paid family and medical leave programs, is essential.
Accurate payroll tax handling reduces audit risks and promotes smoother operations. Employers should also be aware of backup withholding rules as outlined in backup withholding regulations to manage specific tax scenarios effectively.
