What Is IRS Publication 5557 and Why Do You Need It?
IRS Publication 5557, titled “A Guide to Starting a Small Business,” is a user-friendly document from the Internal Revenue Service (IRS) aimed at individuals and entities with assets under $10 million. It focuses on federal tax considerations for opening and operating a small business, including self-employed individuals filing Schedules C, E, F, or Form 2106 with their Form 1040 or 1040-SR.
Why is this guide essential in 2026? With ongoing changes in tax laws, such as those from the Tax Cuts and Jobs Act (TCJA), staying informed helps you claim credits, deduct expenses, and comply with reporting requirements. It’s particularly valuable for beginners, as it covers the stages of business ownership—from starting up to potentially closing down—while linking to additional IRS resources like the Self-Employed Individuals Tax Center and the Small Business Tax Workshop.

Choosing the Right Business Structure: Tax Implications Explained
One of the first decisions in starting a small business is selecting your entity type, as it directly impacts your income taxes, employment taxes, and information returns. Publication 5557 outlines the most common structures:
- Sole Proprietorship: Ideal for single owners; it’s simple but offers no personal liability protection. Income is reported on your personal tax return.
- Partnership: For two or more owners sharing profits and losses. Requires filing Form 1065, with income passing through to partners’ individual returns.
- Corporation: A separate legal entity; subject to corporate income tax (Form 1120). Offers liability protection but involves more paperwork.
- S Corporation: Similar to a corporation but with pass-through taxation (Form 1120-S) to avoid double taxation.
- Limited Liability Company (LLC): Flexible structure with liability protection; can be taxed as a sole proprietorship, partnership, or corporation.
The guide advises consulting legal and tax professionals to choose based on your specific needs, emphasizing how structure affects self-employment taxes and deductions.
Key Stages of Owning and Running a Small Business
Publication 5557 breaks down the business lifecycle into manageable stages, providing tax-focused advice for each:
- Starting a Business: Determine if your activity is a business or hobby (based on profit motive), obtain an Employer Identification Number (EIN) via Form SS-4, and set up recordkeeping systems.
- Operating a Business: Track income sources, deductible expenses (e.g., home office, vehicle use), and basis in property. Use tools like the IRS Tax Calendar to stay on top of deadlines.
- Closing a Business: File final returns, notify the IRS of address or name changes, and handle any outstanding taxes.
It also addresses special topics like the gig economy, Affordable Care Act (ACA) requirements, and foreign bank account reporting (FBAR).
Recordkeeping, Deductions, and Tax Credits: Maximizing Your Benefits
Good recordkeeping is the backbone of tax compliance, according to Publication 5557. It helps monitor progress, prepare financial statements, and support claims on your returns. Key recommendations include:
- Keeping receipts for all expenses.
- Separating business and personal finances.
- Using software or apps for tracking.
The guide highlights deductible business expenses (Publication 334 provides more details) and credits like the Work Opportunity Tax Credit. For self-employed individuals, it covers self-employment taxes and estimated tax payments to avoid underpayment penalties.
Employment Taxes and Hiring Employees
If your small business grows to include employees, Publication 5557 dives into employment taxes. This includes:
- Withholding income taxes (Form W-4).
- Federal Unemployment Tax (FUTA) via Form 940.
- Quarterly federal tax returns (Form 941).
- Distinguishing between employees and independent contractors (using Publication 1779).
It stresses using the Electronic Federal Tax Payment System (EFTPS) for payments and e-filing forms like 940, 941, and 1099-NEC for nonemployee compensation.
Resources and Online Tools for Small Business Owners
Publication 5557 isn’t just a standalone document—it’s a gateway to broader IRS support. Recommended resources include:
