If you are self-employed, you need to complete and file Form 8829 – Expenses for Business Use of Your Home, and claim the deductible expenses on Schedule C – Profit or Loss from Business. If you file Schedule F, Profit or Loss from Farming, you calculate your deduction for business use of your home using the worksheet in Publication 587, and report it in Other Expenses on Schedule F. If you are an employee, you should also use the worksheet and claim the deduction for business use of your home as an itemized deduction on Schedule A.
