The Landlord's Year-End Close and January Reset

Landlord Ledger · Guides for landlords with 2–10 units · Published August 21, 2026 · Updated August 21, 2026

Landlording has a natural year-end, and treating it as one converts April from an excavation into a printout. The work divides cleanly: things that must happen before the year closes, and things that happen once it has.

December — before the year closes

1. Reconcile rent, month by month. Compare rent scheduled under each lease against rent actually received. Every difference should have an explanation you'd be comfortable giving out loud: a partial payment, a concession, a vacancy, an arrear. Explanations are cheap in December and expensive in April.
2. Chase the missing receipts. Scan the bank and card statements for rental spending with no matching receipt. This one pass usually recovers more deductions than any amount of clever tax planning.
3. Do the mileage catch-up. Travel is held to a strict substantiation standard, so a log kept at or near the time of each trip is what actually counts — but if yours has gaps, close them now from calendars and messages while the trips are still verifiable, and fix the habit for next year.
4. Check every contractor has a W-9 on file. Chasing a tax ID in January, after the work is done and paid for, is materially harder than asking before the first payment.
5. Timing decisions, carefully. Spending you were going to do anyway can sometimes sensibly land before or after December 31. Manufacturing expenses purely for a deduction is a different thing, and a worse idea — ask your tax professional rather than the internet.
6. Review rents and renewals for the coming year. Which leases end when, and what the market says. See every date a landlord needs to track.
7. Confirm insurance and registrations are current, and that any local rental registration renews on schedule.

January — the reset

1. Close last year's files. Save a final copy, mark it read-only, back it up somewhere that isn't the machine you use daily.
2. Open fresh files for the new year. For a rent tracker, that means a new file with the new year set; for an expense log, it matters more than people expect — if a year-end summary totals every row in the file without filtering by date, a file spanning two tax years will silently double-count.
3. Issue information returns. Contractors you paid for services in the course of a rental trade or business may need a Form 1099-NEC, Form 1099-NEC is due to both the recipient and the IRS on January 31, with no automatic extension; 1099-MISC recipient copies are also due January 31, but the IRS copy is due at the end of February on paper or the end of March if you e-file. See do I have to send my handyman a 1099? — including the credit-card exception that removes many payments from the obligation entirely.
4. Reconcile deposits held. Security deposits are not income while you're holding them. The year-end balance in your records should match the money actually held, tenant by tenant — including any interest your state requires you to credit.
5. Produce one summary per property. Income, expenses by Schedule E category, and a separate list of capital improvements. That last list is the one your accountant most wants and least often receives.
6. Update the permanent file. Add the depreciation schedule from the return once it's filed, along with any closing statements or improvement invoices from the year. Our retention guide explains why that folder outlives everything else.

What your accountant actually wants

Not the shoebox, and not the bank statements. A per-property summary of income and expenses by category, a list of capital improvements kept separate from repairs, the mileage total with the log available, mortgage interest from Form 1098, and details of anything unusual: a property bought or sold, a refinance, a period of personal use, an insurance claim.

Hand that over and the questions get short. Hand over a folder of PDFs and you'll pay by the hour for someone to do the categorizing you could have done in ten minutes a week.

The five-minute version

If you do nothing else: reconcile rent, chase missing receipts, separate improvements from repairs, get the W-9s, and start a clean file in January. Those five cover most of what goes wrong.
