According to data compiled in tax year 2009, more than 4 million Americans claimed the home-office deduction on their tax returns. That’s about 3 percent of the total 140 million returns filed in 2010. The number is likely to increase this year, with business startup rates having increased substantially in 2011.
Kathy Pickering, executive director of the Tax Institute, research and analysis division of tax-services provider H&R Block (HRB), says the average home-office deduction is valued at more than $2,600. Yet many taxpayers are unclear about how to claim the deduction, or they worry that if they do, they’ll face an IRS audit. Pickering says that although the home-office deduction is scrutinized closely, it should be used by those who are eligible.
