deductible rental loss on rental

look at form 8582 for the calculation of the allowable deduction - line 11

The reduction in your deductible loss may be due to your income.  A taxpayer with a rental property that incurs a loss can deduct up to $25,000 in losses per year if their modified adjusted gross income (MAGI) before the loss is less than $100,000. But for every $2 of MAGI over $100,000, the allowable rental loss is reduced by $1. In other words, the loss is reduced by 50% of the amount that the income goes over the lower income threshold.  Once your MAGI before the rental loss reaches $150,000, the special loss allowance will be reduced to $0.  Losses you aren't allowed to deduct are carried forward for future use.
