Frequently Asked Questions
Federal: No, W-2 employees cannot deduct home office expenses on federal returns since the Tax Cuts and Jobs Act of 2018 eliminated miscellaneous itemized deductions. State: It depends on your state. Texas allows it, California does not, Florida follows federal rules. Check your state's specific regulations.
Simplified Method: $6 per square foot (max 300 sq ft = $1,800). No receipts needed, easy to calculate, but limited. Actual Expense Method: Based on percentage of home used for business. Can include mortgage interest, utilities, insurance, repairs, and depreciation. Requires detailed records but often yields higher deductions.
1) Photos showing only business equipment in the space, 2) Floor plan marking the dedicated area, 3) Documentation showing no personal use (like family room furniture), 4) Client/customer visits to the space, 5) Business mail delivered to that address, 6) Calendar showing consistent business use. The space must be used regularly and exclusively for business.
You can still qualify if your home office is your principal place of business. This means you: 1) Use it regularly and exclusively for administrative/management activities, 2) Have no other fixed location for those activities, 3) Meet clients/customers there. If you have another office, deductions may be limited to the administrative work done at home.
Only the business percentage. If you use internet 60% for business and 40% personally, you can deduct 60% of the cost. For a $100/month bill: $60/month × 12 = $720 deduction. Consider getting a separate business line if usage is high—then you can deduct 100% of that line.
The IRS will disallow unsubstantiated deductions, charge back taxes plus interest (currently ~7%), and may impose penalties (20-40% of underpayment). In severe cases, they can audit previous years. Proper documentation is essential—keep records for 7 years. If you lack proof, the auditor may allow a reduced deduction based on available evidence.
