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.
