Schedule E line 12: mortgage interest paid to banks. Report deductible rental interest paid to banks and similar financial institutions, not the full mortgage payment.
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 12
Include the rental-use share of interest shown by Form 1098 and lender statements, plus the current amortized share of qualifying points and loan costs when reportable with bank interest.
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 principal, escrow funding, property tax, insurance, cash-out interest traced to personal use, or interest paid to a private individual. Other-lender interest belongs on line 13.
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 entering the full payment. A mortgage debit contains interest, nondeductible principal, and often escrow. Split all three every month or reconcile them from the annual lender statement.
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 $2,100 payment contains $1,420 interest, $430 principal, and $250 escrow. Line 12 receives $1,420. Principal goes nowhere, and the escrowed tax or insurance uses its own line only when paid.
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
Points and similar financing costs generally amortize over the loan term. Construction-period interest and debt proceeds used for capital or personal purposes can change treatment, so trace the money.
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 Form 1098, annual loan and escrow statements, amortization schedule, loan-cost schedule, refinance documents, and use-of-proceeds tracing.
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.
