I am filing 1099 misc but our business is from home. How do I calculate how much of the phone bill, mortgage, internet can I write off for business purposes?

The home office deduction lets you deduct things like rent, mortgage interest, insurance, utilities, repairs, and depreciation for the portion of your home used for business. It's available to homeowners and renters alike.

You may be able to claim the home office deduction if your office is used regularly and exclusively for your business and is your principal place of business. In addition, if you're working at home for an employer, your home office must be for the convenience of your employer – not just you.

This means if your employer lets you telecommute as an option, you can't take the deduction. However, if your employer doesn't have their own office or workplace, forcing you to work from home, you may be able to claim the deduction.

When you enter your home office information in TurboTax, we'll determine if you can claim the deduction and how much the deduction is worth.

To enter your home office expense along with other common business expenses:

• Type “Schedule C” in the Search box.
• Select the “Jump to” link.
• Select Add expenses for this work (or Edit and navigate down to Business Expenses).

Remember to enter 1099-MISC, 1099-K, cash, and personal check income from your self-employment before you associate any expenses with your business.

If you’re not self-employed, but a W-2 employee instead, follow this link for the employee home office deduction.
