Hi Romani.

I appreciate you for reaching out to us here on the Community page. It's my pleasure to share with you some information about how QuickBooks Online (QBO) works with company files and accounts.

Usually, each business entity must have one company file or account in QuickBooks Online for tax reporting purposes. It's not ideal to put them into one since each company or LLC will have its own tax ID. Combining them may cause mixed transactions or taxes when reporting to the IRS.

Moreover, an LLC must send its own 1099NEC and a single file can only have 1 EIN.

If your reporting taxes to one entity for these four LLCs, you can use one account for them and set up classes for each LLC. Please know that this feature is only available for QuickBooks Online Plus and Advanced users. You may connect with a professional accountant to help manage your account accordingly.
