Important: A category appearing here does not make an expense deductible. The expense still needs to be ordinary and necessary for your business, properly documented, and any personal portion must be excluded.

How to use this finder

Use the list as a record-review checklist. If a category applies, gather receipts and separate business use from personal use. Then enter only amounts you reasonably expect to qualify in the dedicated deductions calculator.

IRS rule behind the checklist

Schedule C business expenses generally must be ordinary and necessary. Personal, living and family expenses are generally not deductible, and mixed-use costs such as vehicles must be divided between business and personal use.
