Beginning in tax year 2013 (returns which will be filed during 2014), the IRS is offering a simplified option for the Home Office Deduction. If the space in your house that is used exclusively for business on a regular basis is <= 300 square feet, then long gone are the days of keeping track of your cleaning, insurance, utilities and other household expenses. In previous years, the benefit of the deduction usually did not outweigh the trouble for getting together the information needed to make the calculation, especially when you have a self-employed person using a very small part of their house as an office (< 10% of the home). The calculation also confused taxpayers because some parts of the deduction, like mortgage interest and real estate taxes, were allocated between the Schedule A Itemized Deductions and the Form 8829 Expenses for Business Use of Your Home. Then there is the added headache of depreciation, which potentially was recaptured if you later sold the residence that housed the home office (meaning it had to be added back when you sold the house).
The simplified option is as its name implies: simple. Take the square footage of your home office (not to exceed 300 square feet), multiply by $5, and that's your deduction. There is no depreciation allowed and no splitting of household costs - all of your mortgage interest and real estate taxes go to the Schedule A. Some of the characteristics of the deduction will remain the same, such as the space in the home must be exclusively used for business and the deduction cannot exceed your income from the business activity, but overall this simplified method will be much easier for some taxpayers.
It is important to note that the regular (original) option is still available, and can be beneficial to taxpayers that use a significant portion of their home exclusively for business. The benefits of the deduction will be different for a consultant that has a 150 square foot office in their 3,000 square foot home than for a landscaper that has a 1,000 square foot garage used as a shop in a 2,500 square foot home. It would also be beneficial for the taxpayer to do a rough calculation to see if the $5 per square foot is consistent with what they would be getting under the regular method.
