"The IRS has announced a simplified option that many owners of home-based businesses and some home-based workers may use to figure their deductions for the business use of their homes. The new optional deduction, capped at $1,500 per year based on $5 a square foot for up to 300 square feet, is available starting with tax year 2013. Though homeowners using the new option cannot depreciate the portion of their home used in a trade or business, they can claim allowable mortgage interest, real estate taxes and casualty losses on the home as itemized deductions on Schedule A. These deductions need not be allocated between personal and business use, as is required under the regular method. Business expenses unrelated to the home, such as advertising, supplies and wages paid to employees are still fully deductible. Further details on the new option can be found in Revenue Procedure 2013-13.
