A return is a chain of facts and calculations
Form 1040 starts with identity and filing information, then gathers income, adjustments, deductions, tax, credits, payments, and the final refund or amount owed. Tax software performs arithmetic, but the preparer is still responsible for the facts entered and the questions that should have been asked.
Use a fictional example: Sam brings a Form W-2, a bank interest statement, and a Form 1099-NEC for a small side job. The preparer must ask about the work behind the 1099-NEC and the related expenses. Entering the form as miscellaneous income without understanding the activity can produce the wrong return.
Read in this order
First confirm names, taxpayer identification numbers, address, and filing status facts. Next reconcile the income documents and ask about income that may not have arrived on a form. Then review adjustments, the deduction choice, credits, withholding and estimated payments. Finish by comparing the final result with the client's records and expectations.
- Trace each source document to the related return line or schedule.
- Investigate missing forms, duplicates, unusual changes, and numbers that conflict with the interview.
- Read the diagnostics and review the completed return before asking the client to sign.
- For credits covered by paid-preparer due-diligence rules, follow the current interview, knowledge, calculation, record, and Form 8867 requirements.
Software is not the authority
A software interview can help organize the work. It cannot decide whether a client's statement is credible, whether more information is needed, or whether a position has adequate support. Use current form instructions, IRS guidance, the Internal Revenue Code and regulations, and qualified review when a return is outside your training.
