If you “actively participate” in the residential rental activity, you may be able to deduct a loss of up to $25,000 ($12,500 if you’re married, file separately, and live apart from your spouse for the entire year—but if you’re married, file separately and don’t live apart from your spouse for the entire year, you’re not eligible for this break at all) against ordinary (nonpassive) income such as your wages or investment income. You actively participate in the rental activity if you make key management decisions such as whom to rent to, the rental terms, approving capital expenditures, etc. You also can show active participation if you arrange for others to provide services. Active participation does not require regular, continuous and substantial involvement with the property. But in order to satisfy the active participation test, you (together with your spouse) must own at least 10% of the rental property. Ownership as a limited partner does not count. If your adjusted gross income (AGI) is above $100,000, the $25,000 allowance amount is reduced by one-half the excess over $100,000. (If you’re married, file separately and are eligible for the break, the $12,500 allowance amount is reduced by one-half the excess over $50,000.) Under this rule, if the AGI is $150,000 or more ($75,000 or more for eligible married taxpayers who file separately), the allowance is reduced to zero. For these purposes, AGI is modified to some extent, e.g., you ignore taxable Social Security income and the Individual Retirement Account (IRA) deduction.
