Normally rental income and loss are on Line 17 of your 1040. There is however an income limitation that will not allow you to take a loss. Theses losses get carried forward on Form 8582 until you can use them.

Special $25,000 allowance.   If you or your spouse actively participated in a passive rental real estate activity, the amount of the passive activity loss that’s disallowed is decreased and you therefore can deduct up to $25,000 of loss from the activity from your nonpassive income. This special allowance is an exception to the general rule disallowing the passive activity loss. Similarly, you can offset credits from the activity against the tax on up to $25,000 of nonpassive income after taking into account any losses allowed under this exception.

  If you’re married, filing a separate return, and lived apart from your spouse for the entire tax year, your special allowance can’t be more than $12,500. If you lived with your spouse at any time during the year and are filing a separate return, you can’t use the special allowance to reduce your nonpassive income or tax on nonpassive income.

  The maximum special allowance is reduced if your modified adjusted gross income exceeds certain amounts. 

Phaseout rule.   The maximum special allowance of $25,000 ($12,500 for married individuals filing separate returns and living apart at all times during the year) is reduced by 50% of the amount of your modified adjusted gross income that’s more than $100,000 ($50,000 if you’re married filing separately). If your modified adjusted gross income is $150,000 or more ($75,000 or more if you’re married filing separately), you generally can’t use the special allowance.
