Managing Multiple US LLCs as a Non-Resident

A simple system for keeping multiple entities organized, compliant, and separate. More LLCs means more filings — here is how to manage them without losing your mind.

Key Takeaways

  • Each LLC needs its own EIN, bank account, and bookkeeping
  • Each LLC requires a separate Form 5472 + Form 1120 filing
  • You can share a registered agent across multiple LLCs to save costs
  • Inter-company transactions between your LLCs are reportable on Form 5472

Why Have Multiple LLCs?

Non-resident business owners commonly form multiple US LLCs for several reasons:

Liability separation

Different business lines carry different risks. A SaaS product and an e-commerce store should not share the same legal entity — if one faces a lawsuit, the other is protected.

Different business models

A consulting business and an Amazon FBA store have very different operational needs. Separate LLCs keep finances and compliance clean.

Partnership structures

One business may have partners while another is solely owned. Each ownership structure requires its own entity.

Client requirements

Some clients or platforms require a dedicated entity for contractual or invoicing reasons.

Asset protection

Holding real estate or intellectual property in a separate LLC isolates those assets from operational business risk.

The Golden Rule: Separate Everything

The most common mistake with multiple LLCs is commingling — mixing the finances, operations, or records of different entities. Commingling destroys the liability protection that separate LLCs provide and creates a nightmare at tax time.

Critical:If the IRS or a court determines that your LLCs are not truly separate entities (same bank account, same books, interchangeable use of funds), they can "pierce the corporate veil" and treat them as a single entity. This eliminates the liability protection.

The rule is simple: each LLC should operate as if it does not know the others exist. Separate bank account, separate bookkeeping, separate tax filings, and documented arm's-length terms for any inter-company transactions.

Separate EINs

Each LLC must have its own unique EIN (Employer Identification Number). You cannot share an EIN between entities. When applying for multiple EINs:

  • Each LLC needs a separate SS-4 application
  • Foreign owners must apply by mail or fax (one application per entity)
  • The IRS limits online EIN applications to one per responsible party per day, but this does not apply to fax/mail applications
  • Keep each EIN confirmation letter (CP 575) in the corresponding LLC's file

Our SS-4 filer can generate separate SS-4 applications for each of your LLCs. Start an EIN application here.

Separate Bookkeeping

Each LLC needs its own set of books. This means:

Separate bank accounts

Each LLC should have its own business bank account. Never pay LLC A's expenses from LLC B's bank account. If money needs to move between entities, document it as a formal inter-company transaction.

Separate ledgers

Maintain a separate bookkeeping spreadsheet or accounting file for each LLC. If using a spreadsheet, use separate tabs or separate files. If using accounting software, set up each LLC as a distinct company.

Separate receipt folders

Create a folder structure for each LLC: LLC-A/2025/, LLC-B/2025/, etc. Never store receipts in a shared folder — confusion at tax time is guaranteed.

Separate Tax Filings

Each foreign-owned single-member LLC requires its own Form 5472 + pro-forma Form 1120 filing. If you have three LLCs, you must file three separate returns. There is no consolidated filing option for disregarded entities.

Number of LLCsForms RequiredFiling Cost (with our filer)
1 LLC1x Form 5472 + 1x Form 1120$49
2 LLCs2x Form 5472 + 2x Form 1120$98
3 LLCs3x Form 5472 + 3x Form 1120$147
5 LLCs5x Form 5472 + 5x Form 1120$245

Inter-company transactions:If LLC A pays LLC B for services, both LLCs must report this transaction. LLC A reports the payment on its Form 5472, and LLC B reports the receipt on its Form 5472. These must be arm's-length transactions.

What Can Be Shared

While finances and filings must be separate, some resources can be shared to reduce costs:

Registered agent

Most agents offer multi-entity discounts

Formation state

All LLCs can be in the same state

Cloud storage account

Use separate folders per entity

Accounting software license

Set up separate companies within the software

Bank account

Each LLC must have its own account

EIN

Each LLC requires a unique EIN

Tax filings

Each LLC files separately

Operating agreement

Each LLC needs its own

State-by-State Considerations

You do not need to form all your LLCs in the same state. Here are some considerations:

  • Same state: Simpler to manage. One registered agent, one set of state compliance rules. Wyoming is a solid choice for all entities.
  • Different states: May make sense if different LLCs have different needs (e.g., one needs Delaware's court system for investor relations).
  • Annual fee multiplication: Remember that annual state fees multiply. Three Wyoming LLCs cost $180/year in annual reports alone ($60 each). Three Delaware LLCs cost $900/year in franchise taxes ($300 each).

Recommendation: Unless you have a specific reason to use different states, form all your LLCs in Wyoming. It keeps state compliance simple and costs low.

Your Organizational System

Create a master compliance calendar that tracks deadlines for all entities in one view. Include:

  • Federal filing deadline (April 15) for each LLC
  • State annual report due date for each LLC
  • Registered agent renewal date
  • Bank account review dates
  • Monthly bookkeeping dates for each entity
