Which Home Office Expenses Are Tax Deductible?

If you regularly use a dedicated workspace in your home for business, you may be eligible for tax deductions. However, the IRS has strict rules to ensure only legitimate business expenses are claimed.

Common deductible home office expenses include:

  • ✔ Rent or mortgage interest – A portion of your housing cost, based on business use
  • ✔ Utilities – Electricity, water, and internet expenses used for business purposes
  • ✔ Home office furniture – Desks, chairs, and bookshelves used in your workspace
  • ✔ Office supplies – Paper, ink, pens, and other work-related materials
  • ✔ Depreciation of home office space – If you own your home, depreciation on the workspace may be deductible
  • ✔ Repairs and maintenance – Costs for repairing or maintaining your home office
  • ✔ Homeowners or renters insurance – The portion covering the office space
  • ✔ Property taxes – A percentage related to business use of your home

Types of Home Office Expenses

When claiming home office deductions, it's essential to understand the distinction between direct and indirect expenses:

Direct Expenses

These are costs specifically associated with the business part of your home. For example, expenses like painting or repairs made exclusively to your home office are fully deductible.

Indirect Expenses

These are costs that benefit your entire home, such as utilities, mortgage interest, insurance, and general repairs. You can deduct a portion of these expenses based on the percentage of your home used for business. For instance, if your home office occupies 10% of your home's total square footage, you can deduct 10% of these indirect expenses.

Qualifying for the Home Office Deduction

To qualify for the home office deduction, the IRS considers three key factors:

  • ✔ Exclusivity – The workspace must be used solely for business purposes
  • ✔ Regularity – The space must be used on a regular basis for business activities
  • ✔ Precedence – The home office should be the principal place of business or where substantial administrative work is conducted

It's important to note that while dedicating an entire room to your business isn't necessary, your work area should have clearly defined boundaries.

Simplified Method vs. Actual Expense Method

When claiming home office deductions, you can choose between two methods—each with its own advantages and limitations.

1. Simplified Method (Quick & Easy) 🏠

The IRS simplified method allows you to claim $5 per square foot of your home office space, up to 300 square feet.

Example Calculation:

Your home office is 150 square feet.
Deduction = 150 × $5 = $750

Pros:
  • ✔ Simple calculation—no need to track detailed expenses
  • ✔ Reduces record-keeping requirements
  • ✔ Ideal for smaller home offices
Cons:
  • ❌ May result in a lower deduction if actual expenses are higher
  • ❌ Not suitable for those with large home office costs

2. Actual Expense Method (More Detailed) 📊

Example Calculation:

Your home is 1,500 square feet, and your office is 150 square feet.

Business use percentage = 150 / 1,500 = 10%

If your total eligible home expenses = $20,000, the breakdown might look like this:

  • Mortgage interest: $8,000
  • Utilities (electricity, water, internet): $4,000
  • Property taxes: $3,000
  • Homeowners insurance: $2,000
  • Repairs and maintenance: $2,000
  • Office furniture depreciation: $1,000

Applying the business use percentage (10%):
Deductible home office expenses = $20,000 × 10% = $2,000

Can You Switch Between Methods?

Unlike vehicle expense deductions, you can switch between methods each tax year based on what benefits you most.

Filing Requirements

To claim home office expenses for a sole proprietorship:

  • Calculate deductible business expenses using Form 8829 for the relevant tax year (If you choose the simplified method, it doesn't require Form 8829.)
  • Report them on Schedule C of Form 1040.

For partners in a partnership or members of an LLC that hasn't elected to be taxed as a corporation:

  • Use the worksheet in Publication 587 to calculate the home office deduction.
  • Claim it on Schedule E.

Note: S corporations, C corporations, or LLCs taxed as corporations cannot claim the home office deduction.
