What the publication covers
The introduction says “This publication provides basic federal tax information for people who are starting a business.” It adds “It also provides information on keeping records and illustrates a recordkeeping system.” The publication page for this edition reads “Revised: December 2024”.
On scope, the publication says “Only tax considerations are discussed in this Pub.” It also points readers who need business planning help to the Small Business Administration.
Parts of the publication in plain words
- What New Business Owners Need To Know: Table 1, a list of questions that sends you to the matching section.
- Determining Which Type of Business to Use: sole proprietorships, partnerships, businesses owned by spouses, C corporations, S corporations and limited liability companies.
- Getting a Taxpayer Identification Number: the SSN and the EIN, how to apply for an EIN and what to do about a payee’s number.
- Designating a Tax Year and Choosing an Accounting Method: calendar and fiscal years, the cash method and the accrual method.
- Business Taxes: income tax, self-employment tax, employment taxes and excise taxes, plus depositing taxes.
- Hiring Employees and Information Returns: Forms I-9, W-4 and W-2, and the 1099 forms a business may file.
- Penalties for late returns, late payment, missed deposits and information return failures.
- Deducting Business Expenses: start-up costs, depreciation, business use of your home, and car and truck expenses.
- Recordkeeping: why to keep records, what kinds, supporting documents, bookkeeping systems and how long to keep them, ending with a sample recordkeeping system.
Tables, worksheets and forms inside it
- Table 1, What New Business Owners Need To Know About Federal Taxes.
- Table 2, Which Forms Must I File?, which lists the forms for sole proprietors, partnerships, corporations and shareholders.
- Table 3, Period of Limitations, used to decide how long to keep income tax records.
- The sample recordkeeping system: Daily Summary of Cash Receipts, Monthly Summary of Cash Receipts, Check Disbursements Journal, Employee Compensation Record, Annual Summary, Depreciation Worksheet and Bank Reconciliation.
- Pointers to the Simplified Method Worksheet and the Worksheet To Figure the Deduction for Business Use of Your Home, which live in other IRS documents.
On this site, Schedule C and Schedule SE are the sole proprietor forms from Table 2, Form 8829 covers the home office, and the depreciation worksheet page covers the asset side of the books.
The figures that matter
On estimated tax, the publication says “You generally have to make estimated tax payments if you expect to owe tax of $1,000 or more when you file your return.” For a corporation it says “You generally have to make estimated tax payments for your corporation if you expect it to owe tax of $500 or more when you file its return.”
On self-employment tax, it says “Your net earnings from self-employment were $400 or more.” That line is one of two conditions listed for paying SE tax and filing Schedule SE.
On start-up costs, the Business Start-Up Costs section says “You can elect to deduct up to $5,000 of business start-up costs and up to $5,000 of organizational costs.”
On the home office, the simplified method section says “The area you use to figure your deduction is limited to 300 square feet.” It also describes the rate: “you will generally figure your deduction by multiplying $5, the prescribed rate, by the area of your home (measured in square feet) used for a qualified business.”
On records, the publication says “If you have employees, you must keep all employment tax records for at least 4 years after the date the tax becomes due or is paid, whichever is later.”
On identification numbers, it says “you may be subject to a penalty of $50 for each failure.”
Where it points elsewhere
The publication sends readers to other IRS publications for detail, for example “For more information on sole proprietorships, see Pub. 334.” and “For more information on partnerships, see Pub. 541.” For the home office it says “For more information about business use of your home, see Pub. 587.” On this site, Form SS-4 is the EIN application, Form 1040-ES is the estimated tax form, and bookkeeping for a tiny business covers the records side.
Where this comes from
The IRS page About Publication 583 opens with “Publication 583 provides basic federal tax information for people who are starting a business.” It links the PDF and eBook editions and the earlier revisions of the publication.
This page describes the web edition of Publication 583 (12/2024), Starting a Business and Keeping Records, as served on irs.gov on October 30, 2026. The IRS can revise a publication after we read it, and the IRS page controls. General information, not tax or legal advice.
Common mistakes
- Treating a husband and wife business as a Schedule C by default. The publication says “you are partners in a partnership, whether or not you have a formal partnership agreement.” It then describes two exceptions for community property states and for a qualified joint venture.
- Using a social security number where an EIN belongs. The publication says “Do not use your social security number as a substitute for an EIN on your tax returns.”
- Believing the IRS requires one format for the books. The publication says “Except in a few cases, the law does not require any specific kind of records.”
- Switching to the standard mileage rate in a later year. For a car you own, the publication says “you must choose to use it in the first year the car is available for use in your business.”
- Reading the sample books as the required method. The publication says “These sample records should not be viewed as a recommendation of how to keep your records.”
