What You Can Legally Write Off
Business Deductions Cheat Sheet
Every deduction below is 100% legal — but only if a signed resolution authorizing it is on file in your LLC binder. No resolution, no deduction. Here are the write-offs business owners most often miss, and the document that unlocks each one.
Health Insurance01
Medical, dental, and vision premiums paid through the business — often one of the largest write-offs owners leave on the table.
Unlocked by: Health Insurance Plan resolution
Home Office02
The business-use share of your rent or mortgage, utilities, and internet — based on documented square footage.
Unlocked by: Home Office Policy resolution
Vehicle & Auto03
Business mileage or actual costs — gas, insurance, repairs, and depreciation on a vehicle used for the business.
Unlocked by: Vehicle Use Policy resolution
Travel & Meals04
Business travel, lodging, and qualifying meals and entertainment tied to running and growing the business.
Unlocked by: Travel & Meals Policy resolution
Retirement Contributions05
SEP-IRA, SIMPLE IRA, or Solo 401(k) contributions — often the single biggest lever to lower taxable income.
Unlocked by: Retirement Plan resolution
Continuing Education06
Courses, certifications, conferences, books, and professional training that maintain or grow your expertise.
Unlocked by: Continuing Education resolution
"The documentation is the deduction."
If the IRS asks and there's no resolution on file, the deduction is disallowed — even when the expense was completely legitimate. The write-off isn't lost because you cheated; it's lost because you couldn't prove it.
