capitalize, rather than deduct, some costs. These costs are a part of your investment in your business and are called capital expenses. Capital expenses are considered assets in your business. There are, in general, three types of costs you capitalize.
- Business start-up cost (See the note below)
- Business assets
Note: You can elect to deduct or amortize certain business start-up costs. Refer to chapters 7 and 8
Personal versus Business Expenses
Generally, you cannot deduct personal, living, or family expenses. However, if you have an expense for something that is used partly for business and partly for personal purposes, divide the total cost between the business and personal parts. You can deduct the business part.
For example, if you borrow money and use 70% of it for business and the other 30% for a family vacation, you can deduct 70% of the interest as a business expense. The remaining 30% is personal interest and is not deductible. Refer to chapter 4 of IRS Publication 535, Business Expenses, for information on deducting interest and the allocation rules.
Business Use of Your Home
If you use part of your home for business, you may be able to deduct expenses for the business use of your home. These expenses may include mortgage interest, insurance, utilities, repairs, and depreciation. Refer to Home Office Deduction and IRS Publication 587, Business Use of Your Home, for more information.
Business Use of Your Car
If you use your car in your business, you can deduct car expenses. If you use your car for both business and personal purposes, you must divide your expenses based on actual mileage. Refer to IRS Publication 463, Travel, Entertainment, Gift, and Car Expenses. Fo r a list of current and prior year mileage rates see the IRSStandard Mileage Rates.
