Calculate work from home tax deductions for employees and self-employed in 2026. Free WFH tax calculator. Not tax advice.
Tax rules for work from home deductions changed dramatically in 2018 and remain confusing in 2026. W-2 employees: cannot deduct home office expenses at federal level (some states allow it). Self-employed and 1099: can deduct home office plus all business expenses. Our calculator shows exactly what you can deduct based on your employment type.
W-2 employees (federal): Cannot deduct home office since 2018 Tax Cuts and Jobs Act eliminated unreimbursed employee expenses deduction. States that still allow employee home office deduction: California, New York, Minnesota, Pennsylvania. Self-employed and 1099 workers: Home office deduction fully available. Plus: business internet, phone, equipment, supplies, health insurance premiums, retirement contributions, mileage, and more. The self-employed tax treatment is dramatically more favorable.
Maximizing self-employed home deductions: Home office (exclusive use): simplified $5 per sq ft (max $1,500) or regular method (% of actual home costs). Internet: business percentage deductible (if 80% business use: $80 of $100 bill deductible). Phone: business percentage of monthly bill. Computer and equipment: 100% deductible if business use. Office furniture: 100% if exclusive use. Coworking membership: 100% deductible if for business.
Federally: no. The Tax Cuts and Jobs Act of 2017 eliminated the miscellaneous itemized deduction for unreimbursed employee expenses through 2025 — this has been extended. State exceptions: California, New York, Alabama, Arkansas, Hawaii, Minnesota, Pennsylvania allow home office deduction for employees on state return. Solution for W-2 employees: request employer reimbursement through accountable plan — reimbursements are tax-free to you and deductible for employer.
Self-employed home deductibles proportional to office percentage: Rent or mortgage interest, property taxes, homeowners or renter insurance, utilities (electricity, gas, water), repairs and maintenance of home. 100% deductible regardless: business equipment, business software, business phone portion, business internet portion, health insurance premiums, retirement account contributions (SEP-IRA, Solo 401k). Track all receipts throughout the year.
Self-employed example on $80,000 income, 200 sq ft office in 1,000 sq ft apartment with $2,000/month rent: Home office (20%): $400/month × 12 = $4,800 deduction. Internet at 80%: $80 × 12 = $960. Phone at 60%: $60 × 12 = $720. Total WFH deductions: $6,480. At 22% federal + 15.3% SE tax effective rate of 37%: $6,480 × 37% = $2,398 in tax savings.
