Year end is the busiest stretch on a property manager’s calendar. Owners want clean statements. Vendors need 1099s. Your CPA wants everything yesterday.

Your software can help. AppFolio, Buildium, and other platforms now have AI tools that categorize transactions and flag issues fast. That’s useful. But speed isn’t the same as accuracy.

This property management year end checklist covers what to close out before December 31, and the mistakes automation tends to miss.

Why Year End Close Matters More Than Month End

A sloppy month end is annoying. A sloppy year end is expensive.

Errors that sat quietly all year show up now. They land on owner statements, tax forms, and audit files. Fixing them in January costs more time than catching them in November.

Start early. Most property managers who close cleanly begin in October.

Your Property Management Year End Checklist

1. Reconcile every trust account

Trust account reconciliation is the foundation. Reconcile bank balances, book balances, and owner and tenant ledgers for every account. All three should match.

If they don’t, find out why now. A shortfall on one property can hide behind a surplus on another.

2. Review security deposit balances

Security deposits are liabilities, not income. Confirm every deposit is recorded correctly and matches your tenant roster. Check that move outs from this year were refunded or applied on time.

3. Collect missing W9s

You can’t file accurate 1099s without them. Pull a list of every vendor you paid this year. Request W9s from anyone missing one before the holidays slow everyone down.

4. Prepare 1099s for vendors and owners

Property managers typically issue 1099 NEC forms to vendors and 1099 MISC forms to owners for rents collected. Most forms are due to recipients by January 31, or the next business day.

One change to watch this year: for payments made in 2026, the reporting threshold for most 1099 NEC and 1099 MISC payments rose from $600 to $2,000. Confirm the details with your CPA before filing.

5. Finalize owner statements

Owners expect a clean annual summary. Review income, expenses, management fees, and distributions for each property. Look for anything that seems off before it goes out. It’s easier to explain a correction in December than in April.

6. Clear out undeposited funds and open items

Old uncleared checks, stuck payments, and unapplied credits pile up over twelve months. Clean them out so you’re not carrying clutter into next year.

7. Review late fees and charges

Confirm late fees were applied according to your leases and local rules. Automated fee settings can drift, and one wrong setting repeats every month.

8. Back up and lock the period

Once everything is reconciled, save your reports and close the period in your software. This protects your year end numbers from accidental edits.

What AI Won’t Catch at Year End

AI tools are good at patterns. They’re weaker at context. Here’s where human review still matters most.

Deposits that match on amount but not on tenant. A $1,500 payment can land on the wrong ledger and still look correct.

Owner contributions coded as income. When an owner funds a repair, that money isn’t rent. Miscoding it inflates income and throws off their taxes.

Duplicate vendor payments. “ABC Plumbing” and “ABC Plumbing LLC” can look like two vendors. That can mean a double payment and two incorrect 1099s.

Trust shortfalls across properties. Totals can balance while individual properties don’t. Software often won’t flag this on its own.

Security deposits recorded as income. A single category error can create a compliance problem that nobody notices until an audit.

Automation handles the volume. A trained set of eyes handles the judgment. You need both.

Build a Better Year End Process

The cleanest year end closes have one thing in common. They’re not a scramble. They come from a steady monthly review rhythm that catches issues as they happen.

If this year’s close feels like a lot, that’s a sign the process needs support, not more hours.

Frequently Asked Questions

When should property managers start their year end close?
Ideally in October or early November. That leaves time to fix errors before 1099 and owner statement deadlines.

Do property managers send 1099s to property owners?
Usually, yes. Property managers who collect rent on an owner’s behalf typically issue a 1099 MISC. Your CPA can confirm what applies to you.

What is trust account reconciliation?
It’s the process of matching your bank balance, book balance, and individual ledgers so every dollar held in trust is accounted for.

Can AI handle property management bookkeeping on its own?
AI speeds up categorization and flags some errors. It still misses context based mistakes, so human review remains important.
