If I have a home office, and write off a percentage of the home for a home office deduction, is it better to pay all utilities and expenses through the personal account or the business? At one time, I had a mix of both, and now I have mostly started paying through my personal account and keeping an excel spreadsheet that I fill out each year calculating the annual costs. Is there an easier way to track these home office deductions so it’s not so much research each year to gather all of the numbers?
