Bookkeeping for one LLC is a chore. Bookkeeping for multiple LLCs is a different job, and most owners find that out the week they open the second one. The bank feed that used to mean one thing now means two. A transfer between your own accounts becomes a question with legal and tax consequences. Your accounting software wants a second subscription, a second login, and a second set of books that never talk to the first one.
This guide covers what actually changes when you run two, three, or eight LLCs, the five rules that keep the books clean and the liability shield intact, how to record the money that moves between your own companies, and what to look for in software so that you are not reconciling four files by hand every quarter.
An LLC is a legal wall between the business and you. The wall only holds if the books show that the company is a real, separate thing: its own money, its own records, its own decisions. With one LLC that separation is easy to keep. With several, four new problems show up at once.
The five rules below are the minimum that solves all four. They are the same whether you keep the books yourself, use a bookkeeper, or use software that was built for this.
This is the rule with no exceptions, because it is the one that protects the liability shield. Every LLC gets its own checking account. Any LLC with more than a handful of card transactions a month gets its own credit card. Recurring subscriptions get moved to the card of the LLC that uses them, even if that means calling the vendor.
The bookkeeping payoff is immediate: when every transaction on a given account belongs to a single company by definition, half of the classification work disappears. Account equals company. You only have to decide the category, not the owner.
Use the same category names, in the same order, in every company. If the rental LLC calls it "Repairs and maintenance", the consulting LLC does not get to call it "Maintenance". The reason is consolidation: you can only add up columns that mean the same thing. It also makes the tax prep predictable, because your CPA maps each category to a return line once and reuses the map for every entity.
A good multi-LLC chart of accounts has three sections most single-business charts do not: intercompany accounts (loans to and from each sibling company), owner equity accounts split by member, and a "due to owner" account for the times you pay something personally and the company owes you.
This is where most multi-LLC books go wrong, and it is the part every accounting app gets wrong by default. When $25,000 leaves Pine Holdings LLC and lands in Maple Rentals LLC, the bank feed on both sides says "transfer". It is not a transfer. It is one of four things, and you have to decide which before you categorize anything.
| What it is | Paperwork | Accounting entry | Tax effect |
|---|---|---|---|
| Loan | Promissory note: amount, rate, term, payment schedule | Sender: note receivable. Receiver: note payable. Both sides carry the same balance. | Interest is income to Pine and an expense to Maple. Charge at least the IRS applicable federal rate or the IRS can impute it. |
| Capital contribution | Written consent or amendment to the operating agreement | Sender: investment in the receiver (asset). Receiver: member's equity. | No income or deduction. Raises the sender's basis in the receiver. |
| Management fee | Management services agreement with a fee that reflects real services | Payer: management fee expense. Receiver: management fee income. | Deductible for the payer, taxable for the receiver. Must be for actual services at a reasonable rate. |
| Reimbursement | Receipt or invoice showing which company the cost belonged to | Payer: reduces the expense it fronted. Owner of the cost: records the expense. | Moves the deduction to the company that should have it. Not income to anyone. |
The loan is the one that causes the most damage when it is handled as a transfer, because it does not end when the money moves. Take the example above. Pine lends Maple $25,000 in March under a note at 6% with monthly payments of $1,250. Every month from April on, $1,250 leaves Maple and arrives at Pine. In every consumer budgeting app and in most small-business accounting tools, those twelve payments are twelve "transfers" and the note balance lives in a spreadsheet that someone updates by hand, if at all. The correct entry each month splits the payment into principal, which reduces the note on both sides, and interest, which is income to Pine and an expense to Maple. After the first payment the balance is $23,875, not $23,750, and by year end the two numbers are hundreds of dollars apart.
The other money that moves is the money that comes to you. Which entry it gets depends on how the LLC is taxed, and getting it wrong is the fastest way to a painful return.
Keep a separate owner draw or distribution account per LLC and per member. At year end, your CPA needs those balances by entity, not one number across all of them.
A monthly close means every account is reconciled to the bank statement, every transaction has a category, and every intercompany balance matches on both sides. That last check is the one single-business owners never have to do and multi-LLC owners skip most often: if Pine shows a $23,875 note receivable, Maple has to show a $23,875 note payable. If they differ, one side missed a payment entry.
Only after every entity is closed do you consolidate. A consolidated view for the owner is simple in principle: add up income, expenses, assets and liabilities across all companies, then eliminate the intercompany lines so a loan between your own companies does not inflate both your assets and your debts. In practice it is a spreadsheet that someone rebuilds every month unless the software does it.
An LLC is a state-law entity. Federal tax law does not have a form called "LLC"; it assigns each one a tax treatment, and the books for each company have to produce the numbers that treatment needs.
| LLC type | Federal return | What the books must produce | What to watch |
|---|---|---|---|
| Single-member, no election | Schedule C (or E for rentals) on your Form 1040 | Net income by activity, depreciation by asset | Self-employment tax on the full net profit |
| Multi-member, no election | Form 1065, Schedule K-1 to each member | Capital account per member, guaranteed payments, distributions | Capital accounts must reconcile every year |
| Any LLC with S-Corp election | Form 1120-S, Schedule K-1 to each shareholder | Payroll for owners, distributions, shareholder basis | Reasonable compensation; distributions above basis are taxable |
| Holding LLC that owns other LLCs | Depends on its own election; subsidiaries may be disregarded into it | Investment in each subsidiary, intercompany balances | Which layer files what; do not double count income |
Two owners with the same four LLCs can have completely different filings depending on elections. This is also why the S-Corp decision belongs to each LLC on its own: the math in our S-Corp vs LLC guide applies entity by entity, and it rarely makes sense to elect for every company at once.
Most accounting software was built around the idea of one company file. QuickBooks Online is the clearest example: each company is a separate subscription with a separate login, and there is no consolidated report across them without an add-on or an export to Excel. Classes and locations track a dimension inside one file; they do not give each LLC its own balance sheet, and they do not handle a loan between two of your own companies. Consumer apps such as Monarch, Copilot and YNAB go the other way: they can see your business bank accounts, but they treat them as more personal accounts, with no entity, no equity, and no intercompany anything.
Whatever you choose, these are the five capabilities that separate "works for one business" from "works for several":
HaraPro was built for the third item first. Every business you own sits inside one login, each with its own books, and a bank payment can be linked to the specific loan, note or SAFE it belongs to, so the balance and the principal-and-interest split update on both sides by themselves. Before publishing that claim we checked Mint, Monarch, YNAB, Copilot, Empower, Kubera, QuickBooks and Intuit Lacerte; none of them link an individual transaction to the instrument behind it. One business is free forever, which is enough to run the first LLC properly; adding the second is where most people move to a paid plan.
If any item on that list requires opening a spreadsheet, the system has a gap. That is fine at two LLCs and expensive at five. If you want to see how the books look when the software does the intercompany work, the multiple LLCs page walks through a three-entity setup, and our earlier guide to multi-business bookkeeping covers the operating side.
No. Sharing an account commingles funds, which is the main evidence used to pierce the liability shield of an LLC, and it makes it impossible to prove which company a transaction belongs to. Each LLC should have its own account under its own name and EIN.
You need separate books for each LLC, not necessarily separate software. Tools built around one company file, such as QuickBooks Online, require one subscription per company. Multi-entity tools keep every company's books inside one login and add a consolidated view.
Sign a promissory note with an amount, interest rate and repayment schedule. The lending LLC records a note receivable and the borrowing LLC records a note payable. Each payment is split into principal, which reduces the note on both sides, and interest, which is income to the lender and an expense to the borrower.
It can, but it should be booked as a reimbursement or an intercompany loan, never left as an expense of the company that paid it. Move the deduction to the LLC the cost belongs to and settle the balance between the two companies.
A holding LLC can simplify ownership, consolidate distributions and add a layer of protection, but it adds a filing, an account and more intercompany entries. It makes sense once you have three or more operating companies or outside partners in some of them; ask your CPA and attorney before restructuring.
