Multi-Unit Forms

IRS rules do not allow the most popular forms to have multiple units from the same Payer to the same Recipient (e.g., forms 1099-NEC and 1099-MISC). There are exceptions for several types of forms, and these exceptions are to avoid erroneous duplicate filings.

Form types that do allow multiple units require each unit to have a unique value in particular fields.

While you may create multiple units from the same Payer to the same recipient for any of the following forms, you must enter a unique value for each in the boxes specified, below.
