Confirm that the form belongs to the correct taxpayer
Check the recipient name, masked identifying information, account reference and reporting year. A group with several entities may receive statements at the same address, and a bank may issue more than one form. Match each to its legal owner before adding amounts to a tax-preparation workpaper.
The IRS instructions for Form 1099-INT include exceptions for certain recipients, including corporations in specified circumstances. Do not assume every business must receive the form or that receiving none means there is no interest to review. Use the bank records and the entity's tax facts with the preparer to establish what needs reporting.

Read the reported categories separately
Retain the complete statement, including supporting pages and any corrected version. Identify the boxes that contain amounts and ask the preparer to interpret unfamiliar categories. The IRS instructions distinguish ordinary interest, Treasury-related interest, withholding and other items. Combining every populated box into one income total can double count or misclassify information.
Match the form to detailed bank or investment statements. Confirm whether it covers one account or several related holdings. If the issuer supplies a year-end summary, reconcile its components to the individual forms rather than adding the summary and forms together.
Keep original and corrected forms in a clear version history. Mark which document is current, but preserve the earlier one and the reason for correction. A preparer receiving both without context may treat them as separate income records. Record the issuer and account suffix alongside each version to prevent that confusion.

Explain differences from the financial books
Compare the relevant income accounts with the statement amounts and the supporting interest schedules. Differences can require review of timing, accrued income, product classification, fees or entries posted to the wrong entity. Investigate the cause rather than entering a year-end adjustment solely to match the form.
Ask the accountant to separate financial-reporting treatment from tax reporting. An amount already accrued in an earlier book period may later appear in a cash credit or information statement. The workpaper should explain the history so the preparer can apply the appropriate tax rules without counting the same income twice.
For an account with both principal movements and income, use the transaction detail. A large maturity payment is not entirely interest. Keep withholding and penalties, if present, separately identified for professional review rather than subtracting them from bank deposits and assuming the net figure is the reportable amount.
Resolve issuer errors and deliver a complete workpaper
If the form appears wrong, contact the bank or issuer through its established service channel. Provide the account reference and the evidence for the discrepancy, and request its correction process. Do not edit the issuer's PDF and present it as a corrected official statement. Track the request and expected response.
Give the tax preparer the form, relevant account statements, book-to-form reconciliation and any unresolved correspondence. If a correction remains pending near filing, the preparer should determine the appropriate next step based on the entity's circumstances. Avoid treating a requested correction as an accepted one.
After the issue is settled, update the ledger or tax workpaper as supported and retain the final explanation. Check whether the cause, such as an outdated recipient name or incorrect account mapping, also affects other bank records. Fix that underlying record before the next reporting cycle.
