If you own rental real estate and you're not running it through a corporation, your rental income and expenses land on Schedule E (Form 1040), Part I. It's one of the simpler IRS forms once you understand what each line wants — and one of the easiest to get wrong if you wait until April to think about it. This guide walks the form line by line, then covers the two mistakes I see most often as a CPA: misclassifying improvements as repairs, and skipping depreciation entirely.
Before the numbers: the top of Part I
Line 1a and 1b ask for each property's address and type (single family, multi-family, vacation/short-term, commercial, land, royalties, or other). Each property gets its own column — A, B, and C — and if you have more than three properties, you attach additional Schedule E pages and total everything on one of them.
Line 2 asks for fair rental days and personal use days. For a standard long-term rental you never stay in, this is straightforward. If you personally used the property (think vacation homes), the answer can limit your deductions, and it's worth a conversation with your tax professional.
Line 3: Rents received
Total rent collected during the year, per property — on a cash basis for most landlords, meaning rent counts when you receive it, not when it was due. Watch for three things:
- December rent paid in January belongs to the year you received it.
- Security deposits are not income when received — they become income only if you keep some or all of the deposit (for damage or unpaid rent).
- Transfers between your own accounts are not rent. If you move money from your rental checking to savings and your bookkeeping double-counts it as income, your line 3 is overstated and you'll pay tax on money that never existed.
Lines 5–19: the expense lines
Here's what actually goes where:
- Line 5 — Advertising. Listing fees, signage, photos for the listing.
- Line 6 — Auto and travel. Mileage to and from the property for management tasks (use the IRS standard mileage rate or actual expenses, and keep a log).
- Line 7 — Cleaning and maintenance. Turnover cleans, landscaping, gutter clearing, routine upkeep.
- Line 8 — Commissions. Leasing commissions paid to agents.
- Line 9 — Insurance. Landlord/dwelling policies, umbrella coverage allocated to the rental.
- Line 10 — Legal and other professional fees. Attorney fees for leases or evictions, tax prep fees for the rental portion of your return.
- Line 11 — Management fees. Property manager fees — and yes, software subscriptions for managing the property are deductible too (often on line 19).
- Line 12 — Mortgage interest paid to banks. Interest only — not principal. Pull this from Form 1098, not from your payment total. If your payment includes escrow, the taxes and insurance inside it belong on lines 16 and 9, not here.
- Line 13 — Other interest. Interest on a private note or a credit card used for the rental.
- Line 14 — Repairs. Fixes that keep the property in operating condition — more on the repairs-vs-improvements line below, because this is the most audited judgment call on the form.
- Line 15 — Supplies. Filters, batteries, small hardware, cleaning supplies.
- Line 16 — Taxes. Property taxes (often paid through escrow — check your 1098 or county statement).
- Line 17 — Utilities. Water, trash, gas, electric you paid as the landlord.
- Line 18 — Depreciation. The big one landlords skip. See below.
- Line 19 — Other. HOA dues, bank fees, software, anything legitimate that doesn't fit above — itemized, not lumped into one mystery number.
Line 20 totals your expenses, line 21 nets them against rents for income or loss, and line 22 applies the passive loss rules (via Form 8582) to determine how much of a loss is deductible this year. Many active landlords can use up to $25,000 of rental losses against other income, but that allowance phases out at higher incomes — another one for your tax professional.
Mistake #1: Calling an improvement a repair
A repair keeps the property in its ordinary operating condition: patching a roof leak, fixing a faucet, replacing a broken window pane. It's deducted in full this year on line 14. An improvement betters the property, restores it, or adapts it to a new use: a new roof, a kitchen remodel, a room addition, replacing all the windows. Improvements are capitalized and depreciated over their recovery period — not deducted at once.
Why it matters: writing off a $14,000 roof as a "repair" is the kind of line item that draws attention, and the correction is painful. When in doubt, ask whether you fixed a part of something (likely a repair) or replaced/upgraded a whole system (likely an improvement). There are safe harbors — like the de minimis election for items under $2,500 — that your CPA can apply if your records are clean enough to support them.
Mistake #2: Skipping depreciation
Residential rental buildings are depreciated over 27.5 years (straight line). Land is never depreciated, so you allocate your purchase price between building and land first. On a property where the building portion is $275,000, that's a $10,000 deduction on line 18 every year — without spending a dollar.
Some landlords skip it because it feels optional. It isn't. When you sell, the IRS applies depreciation recapture based on the depreciation you were allowed to take — whether or not you took it. Skipping depreciation means paying tax later on a deduction you never used. If you've skipped years, a CPA can usually fix it (Form 3115) and catch up the missed deductions.
The record-keeping that makes this easy
Every line above is trivial if your transactions were categorized when they happened, and miserable if you're reconstructing a year from bank statements in March. The practical fix is per-property books where each expense lands in a Schedule E-aligned category as it clears the bank. That's exactly how Keystead is built — bank transactions auto-categorize into Schedule E-mapped categories via rules, rent auto-matches to tenants, and the year-end export reads like the form itself.

Keystead categorizes your rental transactions into Schedule E lines all year, so tax time is an export — not an archaeology project. Built by a CPA who self-manages rentals.
