Preliminary Work with Taxpayer Data

Start an individual return by confirming identity, household changes and income records. Reconcile the current documents to the prior return before choosing filing status or carrying forward a deduction.

How to work through the decision

  1. 1Collect current facts
  2. 2Reconcile gaps and carryovers
  3. 3Document the return position

Build the file around facts that changed

Start with the taxpayer, the tax year and the people potentially reported on the return. Confirm names and identification numbers against records, then ask about marriage, separation, birth, death, moves and time abroad. A household change can affect more than the dependent entry: it can change filing status, credit eligibility and who has a filing obligation. Collect the facts before accepting the client’s conclusion that someone is a dependent.

Use the prior return as a comparison checklist. Mark recurring wages, interest, retirement distributions, business activities and carryovers. For each item missing this year, establish whether the activity ended, the document is late or a new payer replaced the old one. A prior capital-loss carryover requires the prior computation, not a guess based on last year’s refund. Document the reason for each material change so another preparer can follow the file.

Reconcile receipts without counting them twice

Information returns are evidence, not an exclusive list of taxable income. A payment can be taxable even if no information return arrives. Conversely, a bank deposit can be a transfer, loan or return of principal. Reconcile the underlying transaction to the document instead of adding every dollar from every statement together. If two forms report the same sale or receipt, identify that duplication in the workpaper.

When records conflict, identify exactly what cannot yet be determined. A broker statement with proceeds but no basis calls for purchase records and adjustment history. A business payment total that differs from the books calls for reconciliation of fees, refunds and timing. Do not solve an evidence problem by selecting the number that produces the lowest tax. The next useful action is a targeted request for the missing record or explanation.

Separate a missing fact from a tax judgment

A useful intake note states the fact requested, its source and the decision it affects. “Need more information” is weak. “Need the child’s overnight residence calendar to determine the custodial parent” gives the client a concrete task. Once the evidence arrives, move to the relevant rule lesson. Intake does not itself settle qualifying-child tests or the amount of a basis adjustment.

Before treating the file as ready, reconcile income completeness, carryover continuity and unresolved household questions. Confirm whether an extension or additional payment needs consideration while records are outstanding. An extension generally changes the filing deadline, not the time to pay. The exam often tests this order of operations: investigate an inconsistent fact before applying an otherwise familiar rule.

Original worked example

A prior-year dependent is a question, not an answer

A returning client lists a child from the prior return. The intake sheet says the child moved to the other parent in March.

  1. 1

    Flag the residence change instead of copying the prior dependent entry.

  2. 2

    Ask for the child’s age, residence calendar, support facts and any custody-related release.

  3. 3

    Apply the relevant dependent and filing-status rules only after those facts are complete.

Result

The intake file needs follow-up before the dependent position can be finalized.

A prior return is useful evidence of history; it is not proof of current eligibility.

Apply the method to different facts

Original worked case 2

One receipt appears in two records

A sole proprietor’s ledger includes $24,000 of customer payments. A payment processor reports $9,000, all of which is already included in that ledger. Another $2,000 of cash receipts was omitted. Assume all receipts are taxable business revenue.

  1. Match the processor transactions to the ledger and mark the $9,000 as corroborating evidence, not additional revenue.
  2. Add the omitted $2,000 cash receipts to $24,000. Reconcile any fees separately from gross revenue.
  3. Retain the reconciliation showing why adding all three totals would overstate income.

$26,000 gross revenue before expenses. The missing cash receipt matters even without a form; the processor form does not justify double counting.

Mistakes to catch

  • Importing carryovers without checking that they remain available.
  • Treating a client’s label, such as “dependent,” as the result of the legal tests.

Check your understanding

Does a missing Form 1099 mean the income can be omitted?

No. Determine taxability from the transaction and records. Information returns help reconcile income; they do not define every taxable receipt.

2. A client says a stock sale had no gain because the proceeds were reinvested. What must you establish?

Answer: Obtain sale proceeds, selling costs, adjusted basis and the transaction details.

Ordinary reinvestment does not by itself exclude a gain. The intake task is to assemble the facts needed to test recognition and calculate the result, not accept the client’s description.

3. Last year’s return shows a dependent and a capital-loss carryover. Can both entries simply be imported?

Answer: No. Recheck current dependent eligibility and substantiate the carryover from the prior computation.

These are different evidence problems. Household status can change, while a carryover requires continuity and adjustment for intervening use.
