IRS Publication 587: Definition, Application, and Tax Implications
IRS Publication 587 provides comprehensive guidance on the business use of your home, a critical aspect of tax law for self-employed individuals and business owners. This publication, issued by the Internal Revenue Service (IRS), details the specific criteria and methods taxpayers must follow to deduct expenses related to using a portion of their home for business purposes. Within the realm of tax deductions, the home office deduction can significantly reduce taxable income by allowing eligible individuals to claim a portion of their housing costs as business expenses.
The content of IRS Publication 587 is crucial for understanding the strict "exclusive and regular use" tests, determining what constitutes a "principal place of business," and navigating the complexities of calculating the allowable deduction. It serves as an essential reference for anyone operating a sole proprietorship, freelancing, or engaged in other self-employment activities from a home office.
History and Origin
The concept of deducting expenses for the business use of a home has evolved over decades, reflecting changes in economic activity and the nature of work. The legal framework for the home office deduction is primarily rooted in Internal Revenue Code Section 280A(c), which sets forth the conditions under which such deductions are permitted. Over time, the IRS has issued various forms of guidance, with IRS Publication 587 being a long-standing comprehensive document.
A significant shift occurred with the passage of the Tax Cuts and Jobs Act (TCJA) of 2017. Before 2018, employees could potentially deduct unreimbursed job expenses, including home office costs, as itemized deductions subject to a 2% of Adjusted Gross Income (AGI) floor. However, the TCJA suspended these miscellaneous itemized deductions for employees from 2018 through 202534. As a result, only self-employed individuals, including independent contractors and small business owners, are generally eligible to claim the home office deduction for federal tax purposes during this period33,32. The Tax Foundation has analyzed how the TCJA and subsequent legislation impact various tax provisions, highlighting changes that can affect individual taxpayers31.
Key Takeaways
- IRS Publication 587 outlines the rules for deducting expenses related to using a home for business.
- To qualify, the home office space must be used "exclusively and regularly" for business activities and generally be the "principal place of business"30.
- Only self-employed individuals, independent contractors, and business owners operating from home are typically eligible for the deduction, not employees29,28.
- Taxpayers can choose between a simplified method and calculating actual expenses to determine their home office deduction27.
- The deduction can apply to both homeowners and renters and may include a portion of expenses such as mortgage interest, property taxes, utilities, and insurance26.
Formula and Calculation
Taxpayers generally have two methods to calculate the home office deduction as outlined in IRS Publication 587: the simplified method or the regular (actual expense) method.
Simplified Method:
This method offers a straightforward way to calculate the deduction without extensive record-keeping.
The maximum qualified square footage is 300 square feet, leading to a maximum deduction of $1,500 per year25. If a home office is 150 square feet, the deduction would be (150 \text{ sq ft} \times $5 = $750)24. This method simplifies the calculation but may result in a smaller deduction than the regular method if actual expenses are high23.
Regular Method:
This method requires taxpayers to determine the actual percentage of their home used for business and deduct a corresponding portion of their home expenses.
This percentage is then applied to indirect expenses, which are costs that benefit the entire home, such as rent, insurance, depreciation on the home, gross income, and general repairs. Direct expenses, which apply only to the home office (e.g., office-specific repairs), are fully deductible22.
Interpreting the IRS Publication 587
Interpreting IRS Publication 587 correctly is essential to avoid common pitfalls and ensure compliance with tax regulations. The core of the publication's rules revolves around the "exclusive and regular use" requirement21. "Exclusive use" means the designated space is used solely for business. For example, if a spare bedroom is your office, it cannot also serve as a guest room or a family playroom20,19. "Regular use" implies ongoing, consistent use for business, not occasional or incidental activity18.
Furthermore, for the home office to qualify, it must generally be the taxpayer's "principal place of business." This criterion is met if the home office is where the most important business activities occur, or if it is used to meet or deal with clients, patients, or customers in the normal course of business17. Exceptions exist for certain storage uses or for daycare facilities16. Understanding these distinctions, detailed in IRS Publication 587, is critical for accurately claiming the home office deduction.
Hypothetical Example
Consider Sarah, a freelance graphic designer who works from her home. Her home is 1,800 square feet, and she uses a dedicated 150-square-foot room exclusively for her design business. She meets clients in this room and conducts all her administrative and design work there.
Sarah's annual home expenses include:
- Rent: $18,000
- Utilities (electricity, internet): $2,400
- Renter's Insurance: $600
- Office-specific supplies (direct expense): $500
Using the regular method, Sarah first calculates her business use percentage:
Next, she applies this percentage to her indirect home expenses:
- Deductible Rent: ( $18,000 \times 0.0833 = $1,499.40 )
- Deductible Utilities: ( $2,400 \times 0.0833 = $199.92 )
- Deductible Insurance: ( $600 \times 0.0833 = $49.98 )
Finally, she adds her direct business expenses:
- Total Home Office Deduction = Deductible Indirect Expenses + Direct Expenses
- Total Home Office Deduction = ( $1,499.40 + $199.92 + $49.98 + $500 = $2,249.30 )
Sarah would report these expenses on Schedule C, Profit or Loss From Business, to calculate her net business income.
Practical Applications
IRS Publication 587 is primarily used by self-employed individuals and those operating small businesses from their homes to claim the home office deduction. This includes a wide range of professions such as consultants, artists, writers, online retailers, and independent contractors. The deduction allows these taxpayers to reduce their gross income by a portion of their housing costs, leading to a lower tax liability.
For instance, a freelance writer working from home might deduct a percentage of their rent, utilities, and home insurance. An artist who uses a dedicated studio space in their home for creating and storing artwork could also qualify. The rules specified in IRS Publication 587 are crucial for ensuring that these deductions are legitimate and comply with federal tax law. The IRS provides guidance through various publications and forms, emphasizing the importance of accurate record-keeping for all claimed deductions15. The IRS itself highlights the home office deduction as a valuable tax-saving opportunity for many self-employed taxpayers, provided they meet the specific requirements14.
Limitations and Criticisms
While beneficial for eligible taxpayers, the home office deduction, as detailed in IRS Publication 587, comes with significant limitations and has faced scrutiny. One of the most common restrictions is the "exclusive use" rule, which strictly prohibits any personal use of the designated business space13. Even occasional personal use can disqualify the entire deduction for that space12. This rigidity can be challenging for individuals in smaller living spaces where dedicated, unshared areas are difficult to maintain.
Another major limitation, particularly since the Tax Cuts and Jobs Act of 2017, is the ineligibility of most employees. Prior to TCJA, employees could potentially deduct unreimbursed home office expenses, but this is no longer the case through 202511,10. This change means that many remote workers who use their homes for the convenience of their employer cannot claim this deduction, even if they incur significant costs9.
Additionally, claiming the home office deduction, particularly using the regular method, can have implications when selling the home, as any depreciation taken on the business portion of the home must be "recaptured" and taxed upon sale8. This capital gains consequence is an important consideration for homeowners, as detailed in the IRS guidelines for selling a home with business use.
IRS Publication 587 vs. Home Office Deduction
IRS Publication 587 is the comprehensive guide issued by the Internal Revenue Service that explains the rules for claiming the home office deduction. It is the instruction manual, whereas the "home office deduction" is the actual tax benefit or expense item being claimed.
The publication provides the definitions, eligibility requirements (such as "exclusive and regular use" and "principal place of business"), and calculation methods (simplified and regular) that taxpayers must follow. Without adhering to the guidance in IRS Publication 587, a taxpayer cannot legitimately claim the home office deduction on their tax return. Essentially, IRS Publication 587 dictates how one qualifies for and calculates the home office deduction, while the home office deduction itself is the outcome—the reduction in taxable income for qualifying business expenses related to the home.
