Here’s what HIVE AI had to say about “Can I deduct home office expenses if I’m self-employed?”:

Yes, as a self-employed individual, you can deduct home office expenses on your tax return, but there are specific requirements you must meet to qualify for this deduction.

Requirements for Home Office Deduction

To qualify for the home office deduction, you must use part of your home in one of the following ways:

  • Exclusively on a regular basis as your principal place of business for your trade or business; IRS.gov Tax Topics
  • Exclusively on a regular basis as a place where you meet or deal with your patients, clients, or customers in the normal course of your trade or business; IRS.gov Tax Topics
  • A separate structure that’s not attached to your home, used exclusively on a regular basis in connection with your trade or business; IRS.gov Tax Topics
  • On a regular basis for storage of inventory or product samples used in your trade or business of selling products at retail or wholesale, so long as your home is the sole fixed location of such trade or business;
  • For rental use; or
  • As a daycare facility. IRS.gov Tax Topics

The Exclusive Use Requirement

If the exclusive use requirement applies, you can’t deduct business expenses for any part of your home that you use both for personal and business purposes. IRS.gov Tax Topics This is a strict requirement that the IRS enforces rigorously.

For example, if you’re an attorney and use the den of your home to write legal briefs and for personal purposes, you may not deduct any business expenses for your home office. IRS.gov Tax Topics

No deduction is allowed with respect to a home office unless, as relevant here, “allocable to a portion of the dwelling unit which is exclusively used on a regular basis” as the taxpayer’s principal place of business. If a room used as a home office is also used for other purposes (such as a spare bedroom and exercise room), the taxpayer is not entitled to any home office deduction. Dawson U.S. Tax Court Opinions: Rick Colbert & Traci Marie Kruse-Colbert Dawson U.S. Tax Court Opinions: Rick Colbert & Traci Marie Kruse-Colbert

The costs of a home office that a taxpayer uses exclusively on a regular basis as the “principal place of business for any trade or business” are deductible. But the “exclusive use” requirement makes section 280A an all-or-nothing statute–if the taxpayer uses the home office mostly for business but also uses it for any other reason, there’s no deduction. Dawson U.S. Tax Court Opinions: Denise Celeste McMillan Dawson U.S. Tax Court Opinions: Denise Celeste McMillan

Principal Place of Business Test

Under the principal place of business test, you must determine that your home is the principal place of your trade or business after considering where you perform your most important business activities and where you spend most of your business activity time, in order to deduct expenses for the business use of your home. IRS.gov Tax Topics

A portion of your home may qualify as your principal place of business if you use it for the administrative or management activities of your trade or business and have no other fixed location where you conduct substantial administrative or management activities for that trade or business. IRS.gov Tax Topics

For example, a self-employed plumber’s home office qualifies as a principal place of business for deducting expenses if the plumber uses the home office for the administrative or managerial activities of the plumbing business, even if they have billing done by another company. This does not disqualify the home office from being their principal place of business. If all qualifications are met, including principal place of business, the expenses (subject to certain limitations) can be deducted for the business use of the home. IRS – Publication 587: Business Use of Your Home (Including Use by Daycare Providers)

Deductible Home Office Expenses

Deductible expenses for business use of your home include the business portion of real estate taxes, mortgage interest, rent, casualty losses, utilities, insurance, depreciation, maintenance, and repairs. IRS.gov Tax Topics

Section 280A(c)(1)(A) allows a taxpayer to deduct expenses for the business use of his or her residence. The expenses allocable to a home office may be deducted only if a portion of the residence is regularly and exclusively used as the principal place of business for any of the taxpayer’s trades or businesses. Dawson U.S. Tax Court Opinions: Steven E. Mendelson

For example, a self-employed lawyer who operated his business exclusively out of his home and used a designated home office space that took up approximately 7.83% of the total living space in his 2,400-square-foot home was entitled to a deduction for mortgage interest in proportion to the business use of his home (7.83% × $3,479 = $272). Dawson U.S. Tax Court Opinions: Steven E. Mendelson

Methods for Calculating the Deduction

There are two methods for calculating your home office deduction:

1. Regular Method

With the regular method, you calculate the actual expenses of your home office. This includes:

  • Determining the percentage of your home used for business
  • Applying that percentage to your total home expenses
  • Keeping detailed records of all expenses

Under the regular method for computing the deduction, you may not deduct business expenses in excess of the gross income limitation. However, you may be able to carry forward some of these business expenses to the next year, subject to the gross income limitation for that year. IRS.gov Tax Topics

2. Simplified Method

The simplified method is an alternative to the calculation, allocation, and substantiation of actual expenses normally required to determine your home office expense deduction. With this method, 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. The area you use to figure your deduction is limited to 300 square feet. IRS – Publication 583: Starting a Business and Keeping Records

For example, if you elect the safe harbor method and have 300 square feet of qualified business space, you can determine the amount of your deduction for the qualified business use of your home as $1,500 (300 sq. ft. × $5.00). Rev. Proc. 2013-13

There’s no carryover provision under the safe harbor method, but you may elect into and out of the safe harbor method in any given year. IRS.gov Tax Topics

When using the simplified method, you would still deduct mortgage interest and real property taxes as itemized deductions on Schedule A of Form 1040. You would also deduct ordinary and necessary business expenses that are unrelated to the qualified business use of your home (such as advertising, supplies, and professional fees) as trade or business expenses on Schedule C of Form 1040. However, you may not deduct any portion of the actual expenses related to the qualified business use of your home (such as homeowners’ insurance, utilities, and repairs), and you may not deduct any depreciation for the room on your federal income tax return for that year. Rev. Proc. 2013-13

Limitations on Home Office Deductions

The deduction for business use of your home is limited to the gross income from the business or rental use of the unit, reduced by the sum of the percentage of the otherwise deductible mortgage interest, real estate taxes, losses from casualty and theft, and deductions allocable to the business or rental activity but not allocable to the use of the unit itself. Expenditures required for the activity but not allocable to the use of the unit itself, such as expenditures for supplies and compensations paid to other persons, are not subject to the gross income limitation. IRS IRM 4.10.10 Standard Paragraphs and Explanation of Adjustments

Taxpayers are generally permitted to deduct all ordinary and necessary expenses paid or incurred during the taxable year in carrying on a trade or business. However, taxpayers may not deduct personal, living, or family expenses. Section 280A strictly limits a taxpayer’s deduction for business expenses arising from the use of a home office. A taxpayer may deduct home office expenses only when the taxpayer uses the home office exclusively as his or her regular principal place of business. Taxpayers with qualifying home office expenses may take a deduction only to the extent the taxpayer’s gross income derived from use of the home office exceeds that qualifying expense. Dawson U.S. Tax Court Opinions: Xing F. Wang & Kathleen P. Lee

How to Claim the Home Office Deduction

If you file Schedule C (Form 1040), use Form 8829, Expenses for Business Use of Your Home, to claim the home office deduction using the regular method. IRS – Publication 583: Starting a Business and Keeping Records If you use the simplified method, you’ll calculate the deduction directly on Schedule C.

Warning About Home Office Schemes

Whether an individual is carrying on a bona fide trade or business depends on the facts and circumstances. The actions taxpayers take as part of a home-based business scheme, such as the placing of a filing cabinet in a bedroom, invariably are taken for the purpose of claiming personal, living or family expenses as deductible business expenses, and not for the purpose of carrying on a bona fide trade or business. Home-based business schemes typically are used by taxpayers who perform all of their work at their employers’ place of business. Section 262 disallows deductions for personal, living or family expenses, except as otherwise expressly provided by the Internal Revenue Code. Rev. Rul. 2004-32

With respect to business expenses, only expenses paid or incurred during the taxable year in carrying on a trade or business may be deducted under section 162(a). A trade or business expense deduction under section 162, however, is not permitted with respect to a taxpayer’s residence unless specifically permitted in limited circumstances by section 280A. For example, with respect to the business use of a taxpayer’s residence, section 280A provides that in order for allocable expenses to be deductible under that section, the portion of the taxpayer’s residence must be used exclusively by the taxpayer on a regular basis as a principal place of business for the taxpayer’s trade or business, or to meet or deal with patients, clients or customers in the normal course of the taxpayer’s trade or business. Rev. Rul. 2004-32

Conclusion

Yes, as a self-employed individual, you can deduct home office expenses if you meet the IRS requirements. The most critical requirements are that you use a portion of your home exclusively and regularly for business, and that the space serves as your principal place of business or meets one of the other qualifying uses.

You have two options for calculating the deduction: the regular method (based on actual expenses) or the simplified method (based on square footage). Each has its advantages and limitations, so you should choose the one that provides the greatest tax benefit for your situation.

Remember that the home office deduction is subject to strict IRS scrutiny, so maintain thorough documentation of your business use of the space and ensure you meet all requirements before claiming the deduction.
