What Is IRS Publication 587?
IRS Publication 587 is a document published by the IRS to guide taxpayers through the process of deducting business-related expenses when using part of their home for business purposes. This guide explains the criteria for determining if you qualify for these deductions, what expenses can be deducted, and how to calculate the deductions accurately. The publication primarily applies to individuals who are self-employed or who run a business from their home, including owners, renters, and freelancers.
The publication provides instructions for calculating both the direct and indirect costs of maintaining a home office, offering tax benefits for people who qualify. Whether you’re claiming a portion of your rent, mortgage, utilities, or insurance, IRS Publication 587 helps you understand what you can deduct and how to do it properly.
Who Can Use IRS Publication 587?
You can use IRS Publication 587 if you are self-employed or use your home regularly and exclusively for business purposes. This could include individuals working from home full-time or part-time, as long as they meet the criteria set by the IRS. Here are a few examples of taxpayers who might benefit from this publication:
- Self-Employed Individuals: If you’re running a business from your home, such as an online store, freelance services, or consulting, you may qualify to deduct business expenses from your home.
- Freelancers and Independent Contractors: If you work remotely, even part-time, and use part of your home exclusively for business, IRS Publication 587 can help you understand how to claim deductions.
- Employees Who Work from Home: Under certain conditions, employees who work from home for their employers can also claim deductions related to their home office.
To qualify for the deductions, you need to meet the IRS’s two key requirements: regular use and exclusive use of part of your home for business.

Key Deductions Available in IRS Publication 587
Once you qualify for business use of your home, IRS Publication 587 outlines the types of deductions you can claim. These can include both direct and indirect expenses:
1. Direct Expenses
Direct expenses are costs that are incurred specifically for the business portion of your home. These expenses are 100% deductible. Examples include:
- Renovations or repairs done exclusively to your home office space.
- Office supplies and equipment purchased for business use.
2. Indirect Expenses
Indirect expenses are those that cover your entire home, not just the business portion. You can only deduct a portion of these expenses based on the percentage of your home that’s used for business. Examples include:
- Mortgage Interest: A portion of the interest you pay on your mortgage can be deducted.
- Rent: If you rent your home, you can deduct a portion of your rent.
- Utilities: A portion of your electricity, water, and gas bills can be deducted.
- Insurance: The part of your homeowner’s or renter’s insurance that applies to your home office is deductible.
- Depreciation: If you own your home, you may be able to depreciate the part of the home used for business, providing additional tax savings over time.
3. The Simplified Option
The IRS offers a simplified method for calculating home office deductions. Under this method, you can deduct $5 per square foot of your home office space, up to a maximum of 300 square feet. This can save time and reduce paperwork, but it may result in a smaller deduction compared to the regular method, where actual expenses are calculated.
How to Qualify for Deductions
To claim deductions under IRS Publication 587, you must meet two primary conditions:
1. Regular Use
You must use part of your home regularly for business. This doesn’t mean you have to use it all day, but the space must be used on a consistent basis for business purposes.
2. Exclusive Use
The space you are claiming must be used exclusively for business. For example, if you use a room in your home both for personal and business purposes, you won’t qualify for the deduction. The space must be used only for business activities to meet this requirement.
Common Mistakes to Avoid
Filing for home office deductions can be tricky, and there are several common mistakes that taxpayers make when using IRS Publication 587. These include:
- Not Meeting the Exclusive Use Requirement: Many taxpayers mistakenly use their home office for both personal and business purposes, which disqualifies them from the deduction.
- Failing to Keep Proper Records: You must keep accurate records of your home office expenses and the percentage of your home used for business to ensure you’re claiming the correct deductions.
- Incorrectly Allocating Expenses: When claiming indirect expenses, it’s essential to calculate the correct percentage of your home used for business. Incorrect allocations can lead to missed deductions or errors on your tax return.
