The mechanics: Schedule E to Form 1040
Rental income minus allowable deductions (including depreciation) produces a net figure on Schedule E. That net amount flows to Form 1040, Line 5, and directly increases or decreases your AGI. A profitable rental raises your AGI; a deductible loss lowers it (subject to passive-loss limits).
Rental income is not subject to self-employment tax, which is different from self-employed business income.
Why AGI matters beyond the obvious
AGI is the denominator for dozens of phase-outs and floors. A higher AGI can: (1) phase out the $25,000 rental loss allowance (begins at $100,000 MAGI); (2) reduce or eliminate the IRA deduction; (3) increase Medicare premiums for high earners (IRMAA); (4) push you closer to or past the 3.8% Net Investment Income Tax threshold ($200,000 single / $250,000 married); and (5) reduce itemized deductions in some state tax systems.
Conversely, if rental losses reduce your AGI enough, they can restore eligibility for credits and deductions you'd otherwise phase out of.
Passive loss limits and AGI
If your MAGI exceeds $150,000, passive rental losses cannot reduce AGI at all — they suspend. This creates a situation where rental losses show on Schedule E but produce no current tax benefit, leaving AGI unchanged. The losses carry forward to future years or release at sale. The $25,000 allowance is the exception for active-participation landlords with MAGI below $150,000.
Frequently asked questions
Is rental income included in AGI?
Yes. Net rental income (or deductible loss) from Schedule E flows directly into your AGI on Form 1040.
Does rental income trigger the Net Investment Income Tax?
Net rental income is generally subject to the 3.8% NIIT if your MAGI exceeds $200,000 (single) or $250,000 (married filing jointly). Self-rental income and income from real-estate-professional activities may be excluded.
Does depreciation reduce rental income for AGI purposes?
Yes. Depreciation is deducted from gross rental income on Schedule E, reducing the net amount that flows to your AGI — subject to passive loss limitations.
