Define the business purpose
Separate entities may support distinct ownership, financing, liability management, operations, or future transactions. Those objectives should be evaluated with legal counsel and the tax advisor. Creating another company does not itself create a deductible expense or move income to a lower tax rate. The relationship between entities needs economic substance and accurate records.
Draw an ownership chart showing who owns each entity and its tax classification. A separate state-law entity may be disregarded for federal income tax purposes, while still having other legal or tax obligations. Conversely, an entity with its own return can create additional reporting and intercompany complexity.
Hypothetical services company
An operating business proposes a separate administrative company that will provide bookkeeping and scheduling. Identify actual staff, services, contracts, costs, and pricing. If the same owner controls both companies, a payment between them should not be assumed to reduce the owner’s combined tax bill. The tax treatment depends on the classifications and applicable rules.
Suppose the new entity adds $7,000 of annual accounting, registration, insurance, and banking costs. Compare those costs with the operational and legal benefits identified. A circular flow of management fees unsupported by services is not an adequate business case.
Build the record system first
Use appropriate bank accounts, agreements, invoices, approvals, and consistent accounting. Document shared costs and the method for allocating them. Make clear which entity employs workers, contracts with customers, owns equipment, and carries insurance. Misalignment can create operational disputes as well as tax reporting problems.
Have advisors review related-party rules, state filing obligations, sales tax where applicable, payroll, and retirement-plan aggregation. Separating businesses on paper does not necessarily separate them under every tax rule. Do not assume additional entities allow the owner to duplicate benefits or limits.
Use an intercompany transaction register
List every recurring intercompany payment with the paying entity, receiving entity, service or asset involved, pricing method, invoice schedule, and approval responsibility. Identify the tax classification of both parties. This register gives the advisors a concrete way to evaluate transactions and prevents vague labels such as management fee from substituting for a description of what was actually provided. Update it when staffing or business activities change.
For shared costs, explain the allocation basis. Headcount may be sensible for one expense while actual usage, square footage, or direct identification may be better for another. The method should be consistent with the underlying facts and reviewed for the applicable tax rules. Do not allocate personal costs to whichever entity has income available. Keep the original invoice and the allocation calculation so another person can reproduce the entry.
Reconcile balances between entities at regular intervals. If one company records a receivable and the other records an expense without a corresponding payable, the records disagree. Resolve the cause rather than netting the difference into owner equity. Long-unpaid balances also deserve review: are they trade payables, loans, capital, or incorrectly recorded charges? The answer depends on facts and agreements, not simply how long the item has remained on the books.
At the annual structure review, ask whether each entity still serves its intended purpose. Compare actual benefits with accounting, legal, banking, insurance, and registration costs. If a company is dormant, determine its remaining obligations before closing accounts or stopping filings. Multiple entities can be useful, but the value should come from real operations, ownership, risk management, or transaction needs. The record system should make those reasons visible rather than require an elaborate verbal explanation.
Review the structure annually
Compare actual services and payments with the original plan. Reconcile intercompany balances and investigate aged amounts. If an entity no longer has an operating purpose, evaluate whether maintaining it still makes sense and what closing it would require.
Keep the ownership chart, governing documents, intercompany agreements, allocation workpapers, invoices, and annual cost analysis. A useful structure should be understandable to a new advisor without relying on verbal explanations of what each transfer was supposed to represent.
If staff serve several companies, document how their time and costs are assigned and which entity is the employer. Tell the insurance and benefits providers about the actual operating arrangement. Shared ownership does not make contracts, coverage, or employment obligations interchangeable, and the structure should be reviewed by the professionals responsible for those systems.
