Home Office Deduction for Attorneys: What Solo Lawyers Need to Qualify?
Under IRS guidance, the home office deduction for attorneys generally requires that part of the home be used regularly and exclusively for the trade or business and that it be the principal place of business or otherwise meet one of the IRS tests. Solo attorneys who qualify can figure the deduction under the simplified method, at $5 per square foot up to 300 square feet, or under the regular method using actual expenses.
This article summarizes the IRS rules that matter most to a solo attorney, including who can claim the deduction, what regular and exclusive use means, how the two methods compare, how Form 8829 works, and what records to keep. It covers federal rules only and does not address California rules.

Who Can Claim the Home Office Deduction for Attorneys?
The solo attorney home office deduction is most often discussed for solo practitioners who report business income and expenses on Schedule C. The IRS pages on business use of the home address individuals who use part of their home in a trade or business, and Publication 587 states that the deduction is not available to a person who uses the part of the home as an employee.
That means an attorney who works as an employee of a firm generally does not follow the same rules as a solo attorney running her own practice. Attorneys who practice through a partnership or S corporation should review how home expenses are treated with a tax professional, because the IRS pages cited here focus on Schedule C filers. Attorney tax deductions of this kind depend on the attorney's work status.
For the IRS explanation, see Publication 587, Business Use of Your Home.
Home Office Deduction Requirements: Regular and Exclusive Use
The core home office deduction requirements in Publication 587 are regular and exclusive use. The IRS states that a taxpayer must use a specific area of the home only for the trade or business, and that incidental or occasional business use is not regular use.
For a solo lawyer, regular and exclusive use means the space cannot double as a guest room, a children's study area, or a family workspace if the deduction is claimed. The IRS page on the home office deduction adds that if the use of the home office is merely appropriate and helpful, the expenses cannot be deducted. The solo attorney home office deduction therefore depends on how the space is actually used.
Regular use: the space is used on a regular basis, not just now and then.
Exclusive use: a specific area of the home is used only for the business.
Principal place of business home office: described in the next section.
Principal Place of Business, Client Meetings, and Separate Structures
Publication 587 states that a home office can qualify as the principal place of business when it is used exclusively and regularly for administrative or management activities of the trade or business and there is no other fixed location where the taxpayer conducts substantial administrative or management activities. A principal place of business home office is therefore a facts question, especially for attorneys who also use court, client, or shared office locations. Whether a principal place of business home office exists depends on where the attorney actually does administrative work.
The publication also describes two other situations. A home office can qualify if the taxpayer physically meets with clients on the premises and that use is substantial and integral to the business, and a separate structure, such as a studio, workshop, or garage, can qualify if it is used exclusively and regularly for the business.
Home Office Deduction Simplified Method vs. Regular Method
The IRS describes two ways to figure the deduction. Under the home office deduction simplified method, the deduction is figured by multiplying $5, the prescribed rate, by the area of the home used for a qualified business use, and the area is limited to 300 square feet. The simplified method is available for taxable years starting on or after January 1, 2013, under Revenue Procedure 2013-13, according to the IRS.
Under the regular method, the taxpayer divides the expenses of operating the home between personal and business use. The table below compares the two methods using the points the IRS states.
Point | Simplified method | Regular method |
How the deduction is figured | $5 multiplied by the area used for business | Actual expenses divided between personal and business use |
Area limit | Limited to 300 square feet | Based on the business part of the home |
Form 8829 | Not used when the simplified method is elected | Used by Schedule C filers to figure the deduction |
Records | Records showing the area used and that the use qualifies | Records of the area, expenses, depreciation, and home basis |
A tax professional can compare the two methods for a specific home.

Form 8829, the Gross Income Limit, and Carryovers
Schedule C filers use Form 8829 to figure the allowable expenses for business use of the home under the regular method, and any carryover of amounts not deductible this year. A solo attorney home office deduction under the regular method is figured on that form. The Instructions for Form 8829 state that a taxpayer who elected the simplified method for the year does not use the form.
Publication 587 states that the deduction is limited when the gross income from the business use of the home is less than the total business expenses. The Form 8829 instructions state that if expenses are greater than the current year's limit, the excess can be carried over to the next year, subject to the deduction limit for that year.
For the IRS explanation, see About Form 8829.
Records for Law Firm Home Office Expenses
Publication 587 states that a taxpayer does not have to use a particular method of recordkeeping, but the records must show the part of the home used for business, that the part is used exclusively and regularly for business, and the depreciation and expenses for the business part. The IRS also states that canceled checks, receipts, and other evidence of expenses should be kept.
For the regular method, the publication states that records should also prove the home's depreciable basis, including the original purchase price and any improvements. The IRS states that records should be kept for as long as they are important for any tax law, and refers readers to Publication 583. Law firm home office expenses are easier to support when these records are kept in one folder each year. Attorney tax deductions such as this one are only as strong as the records behind them.
Why Bookkeeping Matters for Business Use of Home?
Business use of home expenses come from the books: utilities, insurance, repairs, and other costs have to be tracked separately from personal spending. When those costs are recorded as they occur, a solo attorney can show what was spent and how it was allocated. Attorney tax deductions are easier to support when the records match the return.
A home office is one of several deductions solo attorneys review. Whether a particular space and a particular method qualify depends on the facts, so attorneys should confirm the requirements with a tax professional before claiming the deduction.
