Missing 1099 documents are one of the most common and misunderstood client issues during tax season. Many clients assume that if they did not receive a form, the income does not need to be reported. From the IRS perspective, the existence of income matters far more than the existence of a form.

A CPA should begin by confirming whether the income source existed at all. Prior year returns, payer histories, Schedule C activity, brokerage summaries, and bank deposits often reveal income streams clients forget to mention. This step is critical because relying only on client memory introduces unnecessary risk.

Once income sources are identified, the next step is form reconciliation. Ask the client for a payer list and compare it against prior year 1099s and current year activity. When available, IRS wage and income transcripts help confirm what the IRS already has on file, but they should not delay filing if deadlines are tight.

If a 1099 is missing but income is clearly earned, the CPA should reconstruct income using reasonable documentation such as monthly statements, year-end summaries, or internal accounting records. Income should be reported even without the form. The form supports income reporting but does not create the reporting obligation.

During review, documentation is essential. Workpapers should clearly explain why income was reported without a form and how the amount was determined. This protects both the firm and the preparer if questions arise later.

FAQs

Should a CPA wait for IRS transcripts before filing?
No. Transcripts help with confirmation but should not delay accurate filing.
