NEW YORK (MainStreet) As part its efforts to reduce paperwork burden, the Internal Revenue Service has created a new simple "safe harbor" option for calculating the home office tax deduction, which is effective with tax year 2013.
This new safe harbor option allows taxpayers with a qualified home office to deduct $5.00 per square foot, up to a maximum of $1,500 (so the maximum allowable area of the home office is 300 square feet), instead of claiming actual expenses.
Normally one would determine the square footage of the home office and divide it by the total square footage of the entire home to come up with a business use percentage. The total costs of the home real estate taxes; mortgage interest on money borrowed to build, buy or substantially improve the home; homeowners and flood insurance; gas and electric; heating oil; water; garbage collection; alarm system, etc. are added up and multiplied by this business use percentage. Depreciation is also allowed on the home office area.
This new option does not simplify the calculation of the home office deduction. It actually makes it more complicated by adding another step to the process. As I pointed out in an earlier tax tip, when you are faced with options you should review each option and do separate tax calculations to see which one will result in the lowest overall tax. You must calculate the home office deduction under the "normal" method, using actual expenses and compare this to what you are allowed under the "safe harbor" method.
