Home Office Deduction Calculator
Estimate your home office deduction, apply business-use percentage, and document your numbers the right way.
Work from home? This calculator helps you estimate your potential home office deduction using both IRS methods—Simplified and Actual Expense—so you can document your numbers and be more tax-ready.
What You’ll Calculate
✅ Simplified Method estimate (square-foot based)
✅ Actual Expense Method estimate (expense + business-use %)
✅ A side-by-side comparison so you can choose the method that’s best for you
✅ A clean “save to records” summary you can screenshot/print
What You’ll Get
📌 Calculator Toolkit Includes
🧮 Home Office Deduction Calculator PDF
📏 Square Footage Worksheet
🧾 Expense Tracker (home office categories)
📊 Method Comparison Summary
✅ Audit-Ready Documentation Checklist
Who This Is For
🚗 Gig workers who do admin work at home (dispatching, planning, bookkeeping)
🧑💻 Freelancers & consultants with a dedicated workspace
🏢 LLCs & S-Corps building clean records for write-offs
📦 Online sellers managing inventory, listings, customer service from home
🧠 Why This Matters
Home office deductions are often missed because people:
don’t track square footage
don’t separate personal vs. business use
don’t keep basic documentation to support the claim
This tool helps you capture the right numbers before tax season stress hits.
How It Works
Step-by-step
📐 Measure your office space (sq ft)
🏠 Enter total home size (sq ft)
💡 Add home expenses (rent/interest, utilities, insurance, repairs, etc.)
📊 Apply business-use % automatically (Actual Method)
🧮 Compare against Simplified Method and save the better result
Best practice: Update quarterly so you’re not guessing in April.

Real-World Example
Derrick runs a small delivery business and does his admin work from a dedicated 10’ x 12’ room. He tracks his utilities and internet monthly and uses this calculator quarterly.
His Simplified Method estimate was fast and clean.
His Actual Method estimate was higher because his rent + utilities were significant.
Result: he chose the higher method and saved a one-page summary for his records.

FAQs
🏠 Can I claim a home office if I use the space sometimes?
Usually no. You generally need consistent business use. Use this calculator to track, but confirm eligibility.
📏 What if I don’t know my home’s exact square footage?
Use your lease, property appraiser record, or a best estimate—then update later when you confirm the official number.
🧾 Which method is better: Simplified or Actual?
It depends. This tool calculates both so you can compare quickly.
📦 What if I run my business from multiple locations?
Use this tool for the home portion and track other business expenses separately.
🧑💼 Is this only for LLCs?
No—this can help sole proprietors, single-member LLCs, and other small business owners (eligibility depends on how you file).
