The IRS allows self-employed workers to deduct home office expenses under two methods — Simplified ($5 per square foot, max 300 sqft) or Regular (actual expenses × business-use %). Our calculator runs both side-by-side, applies 2026 federal brackets, self-employment tax, and your state rate, then tells you which method wins and how much cash you keep.
A Home & Office Basics
We'll use these to calculate your business-use percentage and marginal tax rate.
B Simplified Method
$5 per square foot, capped at 300 sqft ($1,500 max). No receipts required — this is your baseline.
C Regular Method (Actual Expenses)
Enter your annual home expenses. We'll apply your business-use % to indirect expenses automatically (Form 8829 logic).
Side-by-Side Comparison
Estimated Tax Savings

Based on IRS Publication 587 (Business Use of Your Home) and Form 8829, the home office deduction is available to freelancers, independent contractors, and small business owners who use part of their home exclusively and regularly for business.
- Enter your home and office square footage. The tool instantly computes your business-use percentage.
- Pick your filing status, income, and state. We look up your 2026 marginal federal rate and apply your state’s income tax rate (or zero for AK, FL, NV, NH, SD, TN, TX, WA, WY).
- Toggle Renter or Homeowner and fill in your annual home expenses. Homeowners can include mortgage interest, property tax, and 39-year straight-line depreciation.
- Hit Calculate. You’ll see the Simplified and Regular deductions side-by-side, a line-item breakdown, and your total estimated federal + SE + state tax savings.
Simplified vs Regular method — which should you pick?
The Simplified Method is $5 per square foot, capped at 300 square feet (max $1,500 deduction). No receipts, no Form 8829, and no depreciation recapture if you sell your home.
The Regular Method uses actual expenses — rent or mortgage interest, utilities, insurance, repairs, depreciation — multiplied by the percentage of your home used for business. It usually produces a larger deduction for renters in high-cost cities and homeowners with significant mortgage interest, but requires Form 8829 and careful recordkeeping.
Rule of thumb: if your office is larger than 300 sqft, or your share of annual home expenses exceeds $5/sqft, the Regular method wins. The calculator above picks the winner automatically and shows you the dollar difference.

Frequently Asked Questions
Who qualifies for the home office deduction in 2026?
Only self-employed taxpayers filing Schedule C, partners, and certain statutory employees. W-2 employees cannot deduct home office expenses under the Tax Cuts and Jobs Act rules that remain in effect through 2025 tax filings and continue into 2026. The space must be used regularly and exclusively for business — a kitchen table or guest bedroom used for occasional work usually does not qualify.
What is the maximum home office deduction for 2026?
Under the Simplified Method, the cap is $1,500 (300 sqft × $5). The Regular Method has no dollar cap but is limited to your gross income from the business use of your home; unused deductions can be carried forward to future years.
Can I switch between Simplified and Regular methods year to year?
Yes. You may choose a different method each year. However, once you use Regular Method depreciation, you must continue calculating depreciation for recapture purposes if you sell the home, regardless of which method you elect in later years.
Does the home office deduction trigger an IRS audit?
The deduction itself is not an automatic audit flag. Problems arise when the business-use percentage is implausibly high, when the space clearly fails the exclusive-use test, or when claimed expenses are undocumented. Keep a simple diagram with office measurements, 12 months of utility bills, and photos proving exclusive use.
What expenses are 100% deductible vs business-use percentage?
Direct expenses (painting the office, a dedicated business phone line, repairs made only to the office) are 100% deductible. Indirect expenses (rent, utilities, insurance, general repairs) are deductible at your business-use percentage. Software subscriptions, a business VPN, a password manager, and office furniture are separate Schedule C deductions — not part of the home office deduction — and are typically 100% deductible.
Do I have to itemize to claim the home office deduction?
No. The home office deduction is claimed on Schedule C (or Form 8829 for the Regular Method), which reduces your business’s net profit. You can take the standard deduction on Form 1040 and still claim the home office deduction.
What about state income tax on the home office deduction?
Most states that have income tax also accept the federal home office deduction. The calculator applies your state’s top marginal rate to the deduction; nine states (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming) have no state income tax, so your savings come from federal and self-employment tax only.
