Economic entity assumption

The economic entity assumption separates the business's accounting from an owner's personal finances. An owner paying personal rent from a personal bank account has not created an expense of the business.

If the owner uses business cash for personal spending, the business must account for that use of its cash. It should not describe the payment as a business operating expense merely because it came from the business account. The owner's role and the facts determine the appropriate accounting.

This separation applies even when a sole proprietor and the business are not separate legal persons. Accounting separation and legal identity answer different questions.

The reporting entity concept addresses which activities a particular set of reports includes. For example, consolidated reports can represent more than one legal company when the accounting requirements call for their inclusion. The economic entity assumption alone does not decide that boundary.

Apply the boundary before choosing an account

Suppose Elena owns Lakeview Repair. Elena uses a personal card to buy tools that Lakeview receives and uses in customer work. The card identifies who paid; it does not make the tools personal household equipment. Lakeview's records need the tools and the value Elena provided to the business. Elena's personal records need her payment. One purchase enters two sets of records because the owner and business have different positions.

Now suppose Lakeview borrows from Community Bank. Lakeview has cash and an amount to repay. The bank has an amount to collect. The same economic event produces records from two entity perspectives. Copying the bank's entry into Lakeview's books would reverse Lakeview's position.

Reconcile the boundary to evidence

Start with the entity named in the report. Trace each disputed account to the contract, title record, invoice, bank account, or other evidence that identifies whose right or obligation it represents. A balanced ledger cannot prove that owner activity was excluded or that every required entity was included.
