The Internal Revenue Code requires landlords to report rental income and expenses, and Schedule E is where most small California landlords report them. The practical takeaway: year-end is not when you reconstruct the year — it is when you reconcile a file you kept all year. This checklist is about records, not tax advice, and it deliberately does not repeat the tax-deductions guide: that guide covers what is deductible; this one covers how to prove it.
Reconcile the Rent Roll First
Your rent roll must tie to your bank deposits, month by month. For each property and each month, list the rent due, the rent received, any partial payments, any payment-plan installments, any concessions or credits, and any amounts still outstanding at year-end. If the rent roll says $42,000 and the bank shows $40,500, find the $1,500 difference before you file — it is usually a partial payment, a deposit applied to rent, or a payment recorded in the wrong month, and each of those has a different tax treatment.
Separate rent from everything that is not rent. Security deposits held for a tenant are generally not income when received; a deposit applied to unpaid rent or damage becomes income or an offset only when it is applied, and the timing matters. Fees, reimbursements, and laundry or parking income, where applicable, belong in their own lines. A rent roll that lumps deposits, rent, and reimbursements together is a rent roll that will not reconcile.
Gather and Categorize Expenses
Categorize expenses the way Schedule E categorizes them. Advertising, auto and travel, cleaning and maintenance, commissions, insurance, legal and professional fees, management fees, mortgage interest, repairs, supplies, taxes, utilities, and depreciation each have their own line, and an expense filed in the wrong category is an expense that is harder to defend. Keep the receipt, the invoice, and the payment record together for each expense — a bank statement alone, without the invoice, is a weak record.
Repairs versus improvements is the distinction that matters most. A repair that restores a property to its prior condition is generally expensed in the year paid; an improvement that adds value, prolongs life, or adapts the property to a new use is generally capitalized and depreciated. A new roof, a room addition, and a full HVAC replacement are not in the same category as a faucet repair, and treating them the same way is a common audit issue. When in doubt, keep the contractor's scope of work with the receipt — the scope is what proves which category applies.
1099 Vendors: Who Gets One and When
Generally, landlords who pay $600 or more in a year to an unincorporated vendor for services must issue a Form 1099-NEC. That includes many independent plumbers, electricians, handymen, cleaners, and property managers who are not incorporated — but the rules turn on the vendor's entity type, the nature of the payment, and whether the payment was for services versus materials, so do not apply a blanket rule to every vendor.
Collect W-9s before you pay, not in January. A vendor who has already been paid has little incentive to return a W-9 promptly, and a missing taxpayer identification number in January becomes a backup-withholding and penalty problem. Request a W-9 from every new vendor at onboarding, keep it in the vendor file, and confirm the entity type — a vendor who incorporates mid-year changes the analysis.
Mind the January deadlines. 1099-NEC forms are generally due to recipients and to the IRS by January 31, and the deadline does not move because your records are incomplete. Build a January calendar: finalize the vendor list, confirm totals against payments, issue the forms, and file them — then keep copies with the year's tax file.
Close the Property File
Reconcile each property separately. A landlord with multiple properties should be able to produce, for each property, a rent roll, an expense list by category, a mortgage-interest statement, a property-tax record, an insurance record, and a depreciation schedule. Multi-property totals that cannot be broken down by property are a red flag in an audit and a practical problem when one property is sold.
Record vacancies, turnovers, and capital work. Note each vacancy period, each turnover's cleaning and repair costs, and each capital project with its placed-in-service date. Depreciation starts when an improvement is placed in service, not when it is paid for, and a missing placed-in-service date is a missing depreciation start.
Keep the file for the retention period. Tax records should generally be kept for at least three years from the filing date, and longer for property and depreciation records — in practice, keep property records for as long as you own the property plus the retention period after sale. A year-end checklist that ends with "shred everything" is a checklist that creates next year's problem.
Keep year-end records organized
LeaseConnectPro keeps rent rolls, receipts, vendor records, and property files together by property and year, so year-end reconciliation is a review of a complete file instead of a reconstruction from bank statements.
This article is for general informational purposes only and is not legal advice or tax advice. Tax reporting, 1099 requirements, and depreciation rules vary by entity type, property, and the specific facts, and they change — so verify the current IRS rules and consult a California tax professional before filing.
Frequently Asked Questions
Q: Is a security deposit rental income?
A: Generally no, when it is held as a deposit. It becomes income or an offset only when it is applied to unpaid rent or damage, and the timing of that application matters. Keep deposits separate from rent on the rent roll.
Q: Which vendors need a 1099-NEC?
A: Generally, unincorporated vendors paid $600 or more in a year for services. The answer turns on entity type, the nature of the payment, and current IRS rules, so confirm each vendor's status with a W-9 rather than applying a blanket rule.
Q: What is the difference between a repair and an improvement?
A: A repair restores a property to its prior condition and is generally expensed; an improvement adds value, prolongs life, or adapts the property to a new use and is generally capitalized and depreciated. Keep the contractor's scope of work to prove which category applies.
Q: How long should I keep landlord tax records?
A: Generally at least three years from the filing date, and longer for property and depreciation records — in practice, keep property records for as long as you own the property plus the retention period after sale.
