Identify the payable that may require a tax adjustment
An expense can be validly accrued in the books and still require a different federal deduction date. At tax preparation, isolate unpaid rent, interest, compensation and other expenses owed to owners, family members or affiliated businesses. The purpose is to flag relationships for review, not to decide that every affiliated transaction follows the same rule.
IRS Publication 538 explains that business expenses and interest owed to a related person using the cash method are not deductible until payment is made and the amount is includible in that person's gross income. It directs taxpayers to section 267 for the definition of a related person and identifies the relevant year-end relationship test.
Ask the adviser to determine whether that rule or another provision applies to each item. Partnership, corporate, foreign-payee and compensation facts can change the analysis. Do not use a simple 'same owner' flag as a substitute for the applicable ownership, attribution and entity rules.

Provide facts for both sides of the transaction
Collect the payer's tax year and accounting method, the payee's identity and method, relevant ownership information and the agreement creating the expense. Obtain the payee information through an authorized contact. A vendor's invoice date does not tell the company when that vendor includes the amount in income.
Document changes in ownership or entity classification that occurred during the year and give them to the adviser. Record facts as of the relevant dates rather than overwriting the file with the current ownership chart. The preparer needs the relationship applicable to the year under review.
For interest, retain the note, accrual calculation, payment terms and outstanding principal. For services or rent, retain the contract and evidence supporting the amount owed. Resolving the timing rule does not establish that an otherwise unsupported expense is deductible or that its price is appropriate.

Establish what was actually paid and when
Reconcile the opening payable, current accrual, payments, credits and closing balance. Link payments to bank evidence and the specific obligation settled. A journal entry that moves an amount from one related-party account to another does not, without further analysis, establish the payment and income inclusion needed for the deduction.
For a hypothetical $18,000 accrued expense with $5,000 paid and $13,000 remaining at year-end, preserve both amounts for the preparer's timing review. The arithmetic identifies the unpaid portion; it does not determine the deduction by itself. Ask the adviser how the actual payment facts and applicable rule affect each portion.
Flag net settlements, offsets, debt conversions and payments made shortly after year-end. Provide their legal documents and dates rather than describing them all as cash payments. If compensation is involved, coordinate the wage-reporting facts with payroll while leaving the deduction analysis with the tax adviser.

Carry the deferred amount into the next return
Have the preparer document any current-year tax adjustment and the remaining amount awaiting deduction. Maintain a tax schedule by payee, expense and originating year. The ledger payable alone may not preserve the original tax treatment after payments are applied against several years of accrued balances.
When payment occurs, link it back to the originating expense and give the preparer the evidence of the payee's relevant treatment. Avoid claiming the amount once as a later cash payment and again through a general book-to-tax adjustment. A clear release column should show what was previously deferred and what remains.
Retain the relationship review, method confirmation, agreement and payment chronology with the tax workpaper. If the adviser concludes that no timing adjustment applies, preserve that conclusion and its factual basis too. The completed schedule should explain the deduction year without altering the historical accounting entry merely to resemble the tax result.
