How does shareholder funding for business expenses work?
Illustrated tax movement lesson for business and real estate owners.
The direct answer
An owner can contribute capital or make a bona fide direct loan, and the company can use the cash for actual operations. Funding is not itself an expense; the business must classify what it buys. The owner's basis effect is separate from the company's expense treatment.

What the drawing does and does not show
The boxes identify the parties, records or decisions involved in this specific question. A connector showing tax reporting does not mean cash was paid. A cash transfer does not establish a deduction. The transaction must be classified before the return is prepared, and the recipient side must be included in the analysis. Review the actual tax year, legal ownership and any related-party or loss limitation rules before implementing the arrangement.
Put the answer into your own tax file
Start by identifying the taxpayer, the tax year and the actual transaction. Then connect the transaction to the original documents before choosing a return line or moving money between accounts. A payment description can be useful evidence, but it cannot replace the underlying facts.
The records to review for this topic are: Entity classifications, ownership records, transaction documents, payment evidence, books and the relevant filed returns.
For the example above, write down the decision that needs to be made, the missing information and the person responsible for supplying it. Keep the business, payroll, property and personal return teams aligned when more than one set of records is affected.
