The rules for claiming the home office deduction are the same regardless of whether you live in the US or abroad. This boils down to four basic qualifications: You must be self-employed; You must exclusively use your home office for work; You must regularly use your home office for work; and Your home office must be your principal place of business.
You can use the simplified method, which is $5 per square foot of the office or actual expenses, the largest one, which is generally a mortgage. Others are insurance, utilities, repairs, maintenance, and depreciation.
Thank you for the question @cmallow17
