Home Office Receipts: What to Keep and How to Organize Them for Taxes

Why Receipt Organization Matters for Home Office Deductions

The home office deduction using the regular method requires you to track all home expenses and apply a business-use percentage. This is one of the more document-intensive deductions on Schedule C — but it's also one of the largest. Getting organized from January 1 means a clean, defensible deduction at tax time instead of a scramble through 12 months of bank statements in March.

The Receipts You Need to Track

Rent or Mortgage Interest

If renting: monthly rent payments — keep bank records or landlord receipts showing the annual total.
If you own: Form 1098 from your mortgage lender shows mortgage interest paid. Property tax statements show property taxes. Both apply the business-use percentage.

Utilities

Electricity, gas, water — keep monthly statements. Annual totals × business-use percentage = deductible amount. For internet: if you use a single connection for both personal and business, the home office percentage applies. If you have a dedicated business internet line, it's 100% deductible on Line 25 (utilities) rather than through home office.

Homeowner's or Renter's Insurance

Keep the annual policy declaration page showing premium amount. Business-use percentage applies.

Home Repairs and Maintenance

General repairs (roof, HVAC, plumbing) that benefit the whole home: apply business-use percentage.
Repairs specific to the home office space (painting that room, replacing the office floor): 100% deductible — keep those receipts separately.

Home Depreciation (Owners Only)

Requires your home's purchase price, closing costs, and the date you started using the home for business. Depreciation is calculated on Form 8829, not from receipts per se — but keep your original closing documents permanently.

Receipts You Don't Need for Simplified Method

If you use the simplified method ($5/SF, max $1,500), you don't need any of these home expense receipts. The deduction is fixed based solely on your office square footage. Simpler — but potentially leaves money on the table if your actual expenses are high.

The Square Footage Calculation

You need: the square footage of your dedicated office space AND the total square footage of your home. Keep documentation:

A measured floor plan or lease agreement showing total home SF
Your own measurement of the office space (tape measure + notes)
Photos of the dedicated space showing exclusive business use

Business-use percentage = office SF ÷ total home SF. This percentage applies to all general home expenses.

Organizing the Receipts

Simple system that survives an audit:

Create a folder labeled "Home Office [Year]"
Sub-folders: Rent/Mortgage, Utilities, Insurance, Repairs, Internet
Scan and upload monthly — photograph receipts at payment time
Keep a running total spreadsheet: expense type, date, amount
At year-end: sum each category, apply business percentage, enter on Form 8829
