How to Deduct Home Office Expenses

Working from home can save time, reduce commuting stress, and give you more flexibility. But when tax season comes around, the home office deduction is one of those areas where people either miss a legitimate deduction or claim it too loosely.

In this guide, you’ll learn how to deduct home office expenses, who may qualify, how the simplified and actual expense methods work, and what records to keep.

TL;DR: Quick Decision Guide

• If you are an employee working from home → you generally cannot claim the federal home office deduction.
• If you are self-employed and use part of your home regularly and exclusively for business → you may qualify.
• If you want a simpler calculation → use the simplified method.
• If your home expenses are high and you keep good records → the actual expense method may be worth comparing.
• If your workspace is also used personally → it usually does not meet the exclusive-use rule.

Step 1: Know Who Can Claim the Home Office Deduction

The home office deduction is generally for self-employed people, freelancers, independent contractors, and business owners who use part of their home for business.

This may include:

• Freelancers
• Consultants
• Side hustlers
• Independent contractors
• Sole proprietors
• Single-member LLC owners
• Small business owners
• Gig workers with a qualifying workspace

The IRS explains that Publication 587 covers how to figure and claim the deduction for business use of your home, including special rules for daycare providers. A “home” can include a house, apartment, condominium, mobile home, boat, or similar property that provides basic living accommodations. It can also include structures on the property, such as a garage, studio, barn, or greenhouse.

What to do:
Before calculating anything, confirm you are claiming the deduction for business use, not simply because you work from home sometimes.

Step 2: Understand the Regular and Exclusive Use Rule

For most taxpayers, the home office space must be used regularly and exclusively for business.

Regular use means you use the space consistently for business, not just once in a while.

Exclusive use means the space is used only for business. A spare bedroom used only as an office may qualify. A dining table used for client calls during the day and family meals at night usually does not.

The space does not always need to be a full room. It can be a clearly defined part of a room, as long as that area is used only for business.

What to do:
Identify the exact area of your home used for business. If the space has mixed personal and business use, be careful before claiming it.

Smile Money Tip: The home office deduction is about business use, not convenience. A clean, clearly defined workspace is easier to explain and support.

Step 3: Make Sure the Space Is Connected to Your Business

The home office should be tied to your business activity. The IRS says a portion of your home may qualify as your principal place of business if you use it for 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 business.

This may include work such as:

• Client calls
• Bookkeeping
• Scheduling
• Marketing
• Writing proposals
• Managing invoices
• Creating products
• Meeting clients, if appropriate
• Storing inventory or samples, if rules are met

What to do:
Write down how the space is used in your business. A short note now can help you remember the business purpose later.

Step 4: Measure Your Home Office Space

To claim the deduction, you need the size of the business-use area. You may also need the total square footage of your home, depending on the method you use.

Measure:

Measurement	Why It Matters
Home office square footage	Used for both simplified and actual methods
Total home square footage	Used for the actual expense method
Business-use percentage	Home office square feet divided by total home square feet

Example:
If your home office is 150 square feet and your home is 1,500 square feet, your business-use percentage is 10%.

What to do:
Measure the space and save the calculation in your tax folder. If possible, keep a simple floor plan or photo of the workspace.

---

Step 5: Choose the Simplified Method or Actual Expense Method

There are two main ways to calculate the home office deduction: the simplified method and the actual expense method.

Method	How It Works	Best When
Simplified method	Uses a standard rate per square foot, up to a limit	You want easier recordkeeping
Actual expense method	Uses the business-use percentage of eligible home expenses	Your home expenses are high and records are strong

The IRS simplified option uses a prescribed rate of $5 per square foot, with a maximum of 300 square feet, for a maximum deduction of $1,500. The IRS notes that this simplified option reduces recordkeeping burden compared with calculating actual expenses.

What to do:
Compare both methods if your tax software allows it. The simpler method may be easier, but the actual method may produce a larger deduction in some situations.

---

Step 6: Know What Expenses May Count Under the Actual Expense Method

If you use the actual expense method, you may calculate the business-use portion of certain home expenses.

Possible expenses may include:

• Rent
• Mortgage interest
• Real estate taxes
• Homeowners or renters insurance
• Utilities
• Repairs
• Maintenance
• Depreciation
• Security system costs
• Certain HOA fees, depending on use and rules

Some expenses are direct, meaning they apply only to the home office. Others are indirect, meaning they apply to the whole home and must be divided by the business-use percentage.

Expense Type	Example	How It May Be Treated
Direct expense	Painting only the office	May be fully business-related
Indirect expense	Electric bill for whole home	Business-use percentage may apply
Unrelated expense	Landscaping personal yard	Usually not part of home office deduction

What to do:
If using actual expenses, gather bills and receipts for the whole year. Do not guess.

Step 7: Report the Deduction Correctly

If you file Schedule C and use the actual expense method, home office expenses are generally calculated using Form 8829. If you use the simplified method, the calculation may be handled through Schedule C instructions or tax software.

IRS Publication 587 explains both methods and how to figure and claim the deduction for business use of your home.

What to do:
Use tax software that supports business-use-of-home deductions or work with a tax professional if you are unsure.

---

Step 8: Keep Good Records

The home office deduction is easier to claim when your records are clean. Keep proof of both the space and the expenses.

Save:

• Square footage calculation
• Rent or mortgage records
• Utility bills
• Insurance bills
• Property tax records
• Repair receipts
• Photos or notes showing business use
• Business calendar or work records
• Home office expense worksheet
• Form 8829, if used
• Filed tax return

What to do:
Create a “Home Office” folder inside your tax folder. Keep records by year.

When the Home Office Deduction May Not Apply

The deduction may not fit if:

• You are only an employee working remotely
• Your workspace is used personally
• You work from different areas of the home without a defined space
• You only use the space occasionally
• You have another fixed location where you conduct substantial administrative work
• You cannot support the expense records
• The deduction creates more complexity than it is worth

What to do:
If the space does not clearly qualify, do not force the deduction. Focus on other legitimate business expenses instead.

Common Mistakes to Avoid

• Claiming a home office as an employee
• Using a shared family room or dining table as “exclusive” space
• Guessing square footage
• Deducting 100% of home expenses
• Forgetting to compare simplified vs. actual method
• Claiming personal repairs as office expenses
• Not saving utility or rent records
• Assuming an LLC automatically qualifies the home office
• Ignoring depreciation issues with the actual expense method

Final Thought

The home office deduction can help self-employed people and business owners reduce taxable business income, but it works best when the space is real, consistent, and documented.

Do not claim it because working from home feels expensive. Claim it because you have a qualifying business space, clear records, and a method that fits your situation.
