Schedule E line 15: supplies. Report consumable materials and qualifying low-cost items used in rental operations.
Schedule E Part I is a classification form. The total matters, but so does the line because each property gets its own column and the named lines tell a preparer what kind of cost produced the result. The 2025 Instructions for Schedule E are the controlling map for this walkthrough.
What belongs on Schedule E line 15
Include cleaning materials, light bulbs, batteries, filters, small repair parts, office supplies, and other items consumed in the work or expected to last no more than a short period. A consistent de minimis policy can cover qualifying tangible items.
Use the gross amount before netting reimbursements, processor fees, or unrelated costs unless the form instructions specifically call for a net figure. Keep each property tagged from the day the transaction is entered. A portfolio total without property detail cannot rebuild the columns on Part I.
What does not belong here
Do not include inventory held for sale, a durable asset above the expensing threshold, contractor labor, or materials that are part of a capital improvement. Those materials join the project's basis.
Capital improvements do not become current expenses by choosing an operating line. IRS Publication 946, chapter 1, requires capitalization for a betterment, adaptation, or restoration. Those costs go to an asset schedule and reach Schedule E through line 18 depreciation. A repair that merely keeps existing property working can stay current, usually on line 14.
The most common mistake
The common mistake is putting every hardware-store receipt on line 15. Split consumables from a new appliance, tool, building component, or materials installed as part of a remodel.
Do not force a number onto the form because a category name sounds close. Keep the receipt description and facts, then use the line the 2025 instructions name. Line 19 is for valid other rental expenses, not a holding pen for mortgage principal, personal costs, land, or capital work.
A worked Part I example
A $220 receipt contains $80 of filters and bulbs, a $40 can of touch-up paint, and a $100 faucet used in a current repair. Line 15 can hold the consumables under a consistent policy, while repair labor and any capital project remain separate.
The example is a classification exercise, not a promise that the whole resulting loss is usable this year. IRS Publication 925 generally treats rental activity as passive. The active-participation special allowance can permit up to $25,000 of loss against nonpassive income, with the allowance phasing out as modified adjusted gross income moves from $100,000 to $150,000.
Personal use, recovery periods, and records
Qualifying taxpayers without an applicable financial statement can elect the de minimis safe harbor for items at or below $2,500 per invoice or item. Durable equipment not expensed needs its own class life.
Mixed use adds another limit. Under Publication 527, shared costs are divided between rental and personal use. If personal use exceeds the greater of 14 days or 10% of fair-rental days, the dwelling is treated as a home and rental deductions can be limited. The personal share does not move to another Schedule E line.
Keep itemized receipts, property and purpose, inventory of unused major items, written capitalization policy, annual safe-harbor election, and links from materials to any capital project.
The full Schedule E walkthrough shows how the Part I lines assemble. The expense-by-expense deduction library handles the classification behind each receipt. rents.ai keeps the same per-property line order as expenses are logged and computes residential 27.5-year mid-month depreciation for line 18, with no bank login required.
This is general information for preparing 2025 records, not tax advice. Schedule E can feed Form 8582, Form 4562, Form 4684, or other forms depending on the facts. Give your CPA the source records and let them make the filing decisions for your return.
