I'm a sole proprietor running a consulting business from a home office, and I'm trying to get a better handle on my small business tax deductions before the end of the fiscal year. I'm particularly confused about what percentage of my home utilities and internet I can legitimately claim, and whether I can deduct a portion of my vehicle lease for client meetings. For other self-employed professionals, what documentation and methods have you used to track and substantiate these mixed-use expenses, and are there any commonly overlooked deductions you've found valuable?
