US rental deductions: expenses, improvements, and basis

A rental payment can reduce cash today without being a current tax deduction. Separate recurring rental costs, improvements, acquisition costs and debt principal before calculating taxable income. That separation makes the eventual tax return—and a future sale—much easier to explain.

This article uses a hypothetical cash-basis US individual with an ordinary, profit-seeking rental in 2025. The property is entirely rented for the year, with no personal use or substantial guest services. Different ownership and hosting facts need separate analysis.

Start with records that describe the payment

For ordinary residential rent, Schedule E is generally the individual reporting starting point. Eligible costs can include rental interest, property tax, insurance, utilities and maintenance. Keep evidence of the rental purpose and payment period; a category label alone does not establish deductibility. See IRS Topic 415.

Record gross rent separately from amounts withheld by a manager or platform. Retain their settlement statements so collected income, fees and cash received reconcile. For each outgoing payment, keep the invoice, what work was done, payment date and any rental/personal allocation.

An operating ledger helps you see how the property runs. A tax record asks additional questions about timing and capitalization. Repairs, CapEx, and capitalized items: where does this expense belong? explains why operating profit and spendable cash also differ.

A repair is a fact question

An improvement generally has to be capitalized when it betters, restores or adapts the relevant property to a different use. The test can apply to the building structure or a building system. Conditional safe harbours and elections may affect treatment; invoice size alone is not the rule. The IRS tangible-property regulations guidance explains the framework.

Replacing a broken latch to maintain an otherwise functioning door is a different fact pattern from building an additional room. A contractor's description of either as “repairs” does not settle the tax answer. Keep before/after details and ask which property or system the work affects.

Capitalizing means keeping the cost in an asset record for recovery under the applicable rules rather than subtracting it all as this year's ordinary expense. It is still a real cash outflow. For the next step, read US rental depreciation: the deduction, the basis adjustment, and the eventual sale.

Interest, principal and closing costs need separate lines

Use the lender's records to split a loan payment between interest and principal. Paying back principal reduces debt; it is not a rental-interest deduction. Eligibility for interest also depends on the use of the borrowing, not merely the property securing it. IRS Publication 527 discusses rental borrowing and interest.

At purchase, distinguish acquisition costs from costs of obtaining a loan and from future tax/insurance escrows. Certain acquisition legal, title and recording costs enter property basis; loan fees have separate treatment. Do not add every closing-statement entry to the building or deduct the entire statement. IRS Publication 551 explains these categories.

Basis is the tax amount assigned to an asset, subject to later adjustments. It is not the down payment, market value or remaining mortgage. An allocation between land and depreciable assets belongs in the acquisition record.

One property, two reconciliations

Use these hypothetical annual USD inputs for 2025. Assume the operating costs and interest are currently eligible and the room addition must be capitalized. Leave depreciation, tax, opening reserves, loan proceeds and other transactions out.

Income before depreciation is 36,000 − 12,000 − 6,000 = USD 18,000. It excludes the stipulated capitalized addition and principal repayment from current deductions.

Cash remaining from these transactions is 36,000 − 12,000 − 6,000 − 6,000 − 12,000 = USD 0 before tax. That does not mean taxable income is zero. It means the operating cash has been used for debt reduction and an asset addition as well as current costs.

Reconcile the two results: income before depreciation of USD 18,000, less USD 6,000 principal and USD 12,000 addition, leaves USD 0 cash. Depreciation will change the tax calculation without creating another cash payment in this reconciliation.

A calculated loss is not automatically usable

Rental losses can be restricted by at-risk and passive-activity rules. The amount deductible against other income depends on the owner's circumstances; a negative property result alone does not decide it. IRS Publication 925 provides the rules and exceptions.

Personal use requires allocation and can introduce further limits. If you use the property as a home or host guests, do not reuse the full-rental assumptions above. Keep a use calendar and review the applicable tests.

At each bookkeeping review, investigate unexplained manager deductions, loan amounts without an interest/principal split, and large work invoices without asset treatment. Those are prompts to get better records, not automatic tax conclusions.

For Canadian property, Canadian rental deductions: what records and costs belong in your return? covers Canadian rental-income records. Keep that country's capital-cost rules separate from the US basis and depreciation system. A useful annual package contains an income ledger, ordinary-cost ledger, loan split, asset schedule and the original evidence connecting them.
