Bookkeeping for multiple rental LLCs

1. Map owners, properties, and accounts

Make an inventory before importing activity. Give each property a stable name and record its owner separately from the account used to pay a bill. An account nickname alone is easy to misread months later.

This is an organizational example, not a recommendation to use a particular ownership or banking structure. In your inventory, add the account holder, statement location, and person responsible for review. Keep full account numbers out of a shared checklist.

Use consistent property and owner labels in your ledger, document folders, and accountant handoff. If ownership changes during the year, record the effective date and supporting documents instead of silently replacing the old label.

2. Collect the evidence behind the activity

The IRS explains that a recordkeeping system should clearly show income and expenses, and that supporting documents supply information for the books. See its recordkeeping overview.

For each monthly review, gather bank and card statements, rent records, invoices, and receipts. Use a folder structure such as year → owner → month, with property labels on relevant documents. Store purchase, financing, and ownership documents where you can find them separately from routine monthly activity.

For expenses, preserve the payee, amount, date, proof of payment, and a description of what was purchased. More than one document may be needed to tell the whole story. The IRS describes this evidence in What kind of records should I keep?

Attach a short explanation when the statement description is unclear. “Hardware store” is less useful at year-end than a receipt linked to the property and the work performed.

3. Keep a review list for exceptions

Suppose the owner pays an Oak rental repair using a personal card. Save the invoice and payment evidence, identify Cedar LLC and Oak rental as the context, and note whether any reimbursement has occurred. Ask your accountant how to record the transaction for your circumstances.

Keep similar questions together: one bill covering several properties, money moving between accounts held by different owners, missing receipts, and descriptions that do not explain the purpose of a payment. Record the facts before choosing an accounting treatment.

For each unresolved item, list the date, amount, accounts involved, related properties, evidence location, question, and reviewer. After resolution, retain the decision and its supporting record so next month does not begin with the same investigation.

4. Repeat the same month-end routine

1. Check completeness. Confirm that every account in the inventory has its statement and that the review covers the same period.
2. Review transaction context. Check owner and property labels, supporting documents, and possible duplicate imports.
3. Reconcile each account. Compare the ledger with its statement and investigate differences. Do not insert an unexplained adjustment just to make balances agree.
4. Resolve exceptions. Work through the review list with your accountant and preserve the decisions.
5. Review reports and their scope. Confirm the owner, properties, date range, and accounting basis shown. Ask what a combined view includes before relying on its totals.
6. Prepare the handoff. Share the ownership inventory, reconciliations, agreed reports, supporting records, and remaining questions through your usual secure channel.

Keep a dated copy of the handoff and a record of later corrections. A repeatable process makes it easier to see which month is ready for review and which still has open questions.

5. Use the monthly checklist

The free CSV opens in Excel, Google Sheets, or another spreadsheet app. Make a copy for each month and owner, then add a reviewer and status. It is a task list, not a ledger or tax form.
