Every LLC needs its own bank account and its own credit card. This is the non-negotiable starting point. If you are paying a roofing repair on Property B’s building with Property A’s bank account, you are commingling funds. Commingling is exactly what courts look for when deciding whether to “pierce the corporate veil” and remove the liability protection your LLCs were designed to provide. The whole reason you set up separate entities was to keep them separate, and that separation has to show up in the finances.

In your accounting software, each LLC should have its own company file or its own set of books. In QuickBooks Online, that means a separate QBO subscription for each entity. Some investors try to track everything in one file using classes or tags, but this creates risk. If you ever need to show a lender, auditor, or court that an LLC’s finances are truly independent, a shared file makes that harder to prove. Separate files are cleaner and worth the additional subscription cost.

For each LLC, track rental income, property expenses, mortgage payments, insurance, repairs, and property management fees within that entity’s books. Record owner contributions when you put money into the LLC and owner distributions when you take money out. These equity transactions need to be documented properly, not just lumped in with income or expenses.

The tricky part for most real estate investors is handling shared expenses. Maybe you pay one insurance policy that covers multiple properties, or you hire one contractor to do work across buildings in different LLCs. When that happens, you need to allocate the cost to each LLC based on a reasonable method and document the split. Pay from one LLC’s account, then record reimbursements from the other LLCs. Or better yet, pay directly from each LLC’s account for its share.

If one LLC pays an expense that belongs to another, record it as a due-to/due-from between the entities and settle it quickly. Letting intercompany balances pile up month after month looks like the entities aren’t truly operating independently.

Keep a consistent schedule for reconciling every LLC’s accounts. When you have three or four entities, it is easy to let one fall behind because the property is “low activity.” But a missed month turns into a missed quarter, and by year end your accountant is guessing at transactions. Even if a property only has a handful of transactions per month, reconcile it monthly.

The effort to maintain separate books for each LLC pays off at tax time and protects you legally. If this feels like a lot to manage on your own, working with bilingual bookkeeping services that understand multi-entity real estate accounting can save you time and keep every LLC’s records where they need to be.
