Most landlords miss out on major tax savings simply because rental income, depreciation rules, and safe harbor elections can be confusing. Whether you manage one property or several units, the IRS requires accurate Schedule E reporting and proper treatment of rental expenses. Understanding depreciation, safe harbor elections, passive loss rules, and real estate professional opportunities helps you legally reduce your tax burden and avoid mistakes that raise red flags. With the right strategy, more of your rental income stays in your pocket—not lost to unnecessary taxes or IRS issues.
