Common Mistakes to Avoid
❌ W-2 employees cannot claim this
The home office deduction is only available to self-employed individuals and business owners. W-2 employees cannot deduct home office since 2018.

The space must be used ONLY for business. A desk in the bedroom doesn't qualify. A dedicated room or partitioned space does.
