THE KEY TAKEAWAYS
- Reconcile rental income before reviewing deductions.
- Separate operating expenses, loan principal, and capital purchases.
- Keep documentation for each property and each allocation.
Start with all rental income
Rental income can include advance rent, lease cancellation payments, and expenses a tenant pays on your behalf. A genuinely refundable security deposit is generally excluded when received; a deposit designated as the final month’s rent is advance rent. Most individual landlords use the cash method, which generally recognizes rent when actually or constructively received.
Create a rent reconciliation for each property. Compare your lease ledger with the manager’s annual statement, bank deposits, and any information returns. Put unexplained differences on a short exception list. A transfer from your personal savings account, for example, should have a clear description so it is not mistaken for rent.
Identify ordinary rental operating expenses
Common expenses include rental advertising, management fees, insurance, utilities, property taxes, qualifying interest, maintenance, and professional fees related to the rental. The expense must have a rental purpose, and its timing and treatment depend on the applicable tax rules. An invoice alone does not establish that a payment is currently deductible.
Use consistent categories throughout the year. Attach the vendor invoice to the payment record and identify the property, service dates, and reason for the work. For a portfolio, a separate property column is often more useful than creating dozens of nearly identical expense categories. Flag unusual items instead of forcing them into the closest category.

Separate cash spending from tax deductions
Mortgage principal is not a rental expense deduction. Improvements generally become part of the property’s capital cost, recovered under depreciation rules, rather than an immediate repair deduction. Your own unpaid labor is not a deductible expense. Cash method landlords also cannot deduct rent they never collected and never included in income.
Build a bridge between your cash report and your tax records. Give mortgage principal, purchases, owner contributions, and owner withdrawals their own places in the ledger. When a single payment includes several components, retain the supporting breakdown. That makes it easier to explain why cash flow can be positive while taxable income is low, or why cash flow can be tight even in a profitable tax year.
Review personal use and shared costs
A property used for both rental and personal purposes requires an allocation, and additional limits can apply when it is treated as a residence under the vacation home rules. Renting a room in your home also requires attention to which expenses benefit only the rental space and which benefit the entire property.
Keep an occupancy calendar alongside expense records. Identify the person using the property, dates, rent charged, and any personal use. For shared expenses, preserve the calculation and the facts behind it, such as the floor plan or usage records. Discuss the appropriate allocation method before applying one percentage to every expense.

Make your annual review actionable
Prepare one folder for income, one for operating costs, and one for property purchases and improvements. Include your prior depreciation schedule and a list of changes: new rental units, refinances, changes in ownership, personal use, or a property sale. A one-page summary of unresolved items helps your preparer focus on the decisions that need judgment.
For your next review, choose one property and trace a month from the lease ledger through the bank statement to the expense documents. Correct duplicate entries and missing descriptions while the transactions are still familiar. Repeat that process across the year before treating the annual totals as final.

MAKE IT PRACTICAL
Example: a tenant pays for a repair
Assume monthly rent is $1,800. With your approval, the tenant pays a $150 plumbing bill that is your responsibility and sends you $1,650. Your reconciliation starts with $1,800 of rental income and separately reviews the $150 plumbing cost for deductibility. Recording only the bank deposit hides both the full rent and the repair. This example assumes an ordinary repair with no capitalization requirement.
