Managing Multiple Businesses in QuickBooks: One Company File per EIN
One QuickBooks Online subscription covers one EIN. See how to structure books for multiple LLCs, split the bank accounts, and add a consolidated view.

Take over the books for a household with several businesses and one checking account, and the software question lands before the accounting one. The shape is common: two LLCs with separate EINs, each holding rental property, one spouse earning 1099 commission income, and a few rentals in personal names. Everything runs through one account, the history is unrecorded, and prior returns are unfiled. Here is the structure we recommend and where QuickBooks fits in it.
Does one QuickBooks Online subscription cover two EINs?
No. Each QuickBooks Online subscription carries a single company, and a company maps to one EIN. Two LLCs with separate federal IDs need two subscriptions, because each entity files its own return. Intuit prices the product per company, not per household or per bookkeeper.
One Intuit login can hold several subscriptions, so you can switch between companies without signing out. That helps the person doing the work. It does not change the billing, and it does not create a combined view.
Classes and locations do not solve this either. They track divisions, properties, or revenue streams inside one entity. Class reports are useful for management. They are not separate books, and they cannot support two distinct tax filings.
Does QuickBooks Desktop change the math?
Somewhat. Desktop licenses have traditionally allowed multiple company files under one license, so the cost curve flattens as entities multiply. That is the real structural difference. Each file is still its own set of books.
Desktop brings tradeoffs. It runs on Windows, remote access requires hosting, and the current desktop lineup is subscription priced by tier and users. Before deciding on price, total the full package for your entity count: extra online subscriptions on one side, desktop plus hosting on the other.
Start with the bank accounts
The software choice is the smaller problem. The larger one is that entity and personal money share a single account, which makes clean per-entity books slow and expensive to reconstruct. Open a checking account for each EIN and one for the household. Move all new activity onto those accounts from a fixed cutover date.
This gives the historical cleanup a defined end point. After the cutover, the books stay separated by structure rather than by manual sorting. Modest account fees are a small price next to the hours that untangling keeps costing.
Can you see everything in one view?
Not natively in QuickBooks Online. There is no built-in report that consolidates multiple companies. The standard pattern is a reporting layer on top: export each company’s trial balance to a spreadsheet on a schedule, or connect a third-party reporting tool that reads several QuickBooks Online companies and combines them.
Treat that layer as management reporting. Tax filings, and any audit, come from each entity’s own books.
Rentals held in personal names belong outside both LLC files. A separate personal file, or even a careful spreadsheet, keeps them visible for the household picture without contaminating the entity returns.
Is there a better option than QuickBooks?
Sometimes, but rarely for the reasons people hope. Most cloud accounting products also bill per organization, so two EINs still mean two subscriptions. True multi-entity packages exist in the mid market, built for groups that consolidate formally. Their cost and complexity rarely fit a family business at this scale.
Switching tools also does nothing about mixed accounts or missing history. Those are the expensive items. Solve them first; the ledger brand is the cheap part of this project.
Rebuild the backlog one entity at a time
With prior years unrecorded and unfiled, sequence matters. Pick the oldest open year and one entity. Gather bank statements, loan documents, and closing statements for property purchases and sales. Reconstruct that year, then roll forward for the same entity before starting the second one.
Finishing one LLC first lets a CPA prepare that return while you keep working. The individuals’ returns, including the 1099 income and the personal rentals, are separate filings and need their own clean summary.
If some of the history already sits in one mixed file, splitting a single company into per-entity files is a conversion job we handle ourselves, and it is often cheaper than rebuilding by hand.
The order we would follow
Set a cutover date. Open the accounts: one per EIN, one personal. Rebuild the oldest year for one LLC, then add the second entity and the personal picture. Choose the reporting layer last, once the books underneath it are trustworthy. That order holds up whatever software you end up running.
