Schedule E (Form 1040) is where rental income and expenses live. For a 2-4 unit owner, it is also a map of every deduction you are entitled to — and most landlords leave real money on the table by not tracking deductible expenses all year. Here is the line-by-line guide.
How Schedule E Works for Multi-Unit Properties
Each property gets its own section (line items A, B, C...). A duplex is one property with two rental units — report it once, with combined income and expenses. Expenses are entered by category; the net result flows to your 1040.
The Deduction Lines, Explained
| Schedule E Line | What Goes There | Don't Forget |
|---|---|---|
| Advertising | Listings, photos, signage | Vacancy marketing counts |
| Auto & travel | Mileage to the property, supply runs | Track miles contemporaneously (67¢/mile class) |
| Cleaning & maintenance | Turnover cleaning, lawn, snow, handyman | Small frequent costs add up fast |
| Commissions | Leasing agent fees | Not broker sale commissions (those are basis) |
| Insurance | Landlord policy premiums, liability umbrella (rental share) | Not your personal home policy |
| Legal & professional | Attorney, CPA, bookkeeper, eviction filings | Lease drafting is deductible |
| Management fees | Property manager or software fees | Even self-managers can deduct software |
| Mortgage interest | From Form 1098 per property | Split correctly across properties |
| Other interest | HELOC interest used on the rental | Document use of proceeds |
| Repairs | Deductible repairs (not improvements) | See our repair vs. improvement guide |
| Supplies | Filters, bulbs, smoke batteries | Keep receipts |
| Taxes | Property taxes, rental licensing fees | Reassessments count when paid |
| Utilities | Owner-paid water, trash, common electric | The RUBS-recoverable portion shows here |
| Depreciation | Building + improvements + 5-yr assets | The biggest line — see our depreciation guide |
| Other | HOA dues, bank fees, RUBS admin, pest control | Catch-all with documentation |
The Deductions Landlords Most Often Miss
- Mileage: 12 trips a year at 30 miles round trip is ~$240 of deductions most people never log.
- Home office: a dedicated space used regularly for the rental business qualifies for the simplified $5/sq ft method (capped at 300 sq ft).
- Phone/internet (business-use %): the portion used for managing properties.
- Education: landlord association dues, real estate investing books and courses tied to your activity.
- Bank and software fees: ACH processing fees, late-payment platform charges, accounting software.
- Pre-rental expenses: costs incurred while getting a newly purchased property ready for its first tenant are deductible once the property is available for rent.
- Points and loan costs: amortized over the loan term — most owners forget them after year one.
Documentation: The 3-Year Rule
Keep leases, receipts, invoices, mileage logs, and bank statements for at least 3 years after filing (6 years if income is substantially understated). The cleanest system:
- A dedicated bank account and credit card for each property (or at minimum per-portfolio)
- Monthly categorization in software like Stessa or Buildium (see our software comparison)
- A year-end fixed-asset schedule for depreciation
The Passive Loss Rules (Know Your Limits)
Rental losses (common with depreciation) are passive by default:
- They offset passive income (other rentals) without limit
- Active participation + MAGI under $100,000 lets you deduct up to $25,000 of rental loss against ordinary income, phasing out between $100K-$150K MAGI
- Above that, losses suspend and carry forward — they are not lost
- Real estate professionals (750+ hours, material participation) have no limitation
A Worked Snapshot
Duplex: income $38,400; expenses $18,900; depreciation $10,478.
- Schedule E net: $38,400 − $18,900 − $10,478 = $9,022 loss
- With active participation and MAGI of $85,000: the full $9,022 offsets W-2 income
- Effective result: positive cash flow, negative taxable income
That asymmetry is the core tax advantage of small multifamily ownership.
